  1. Neuropsychological deficits in patients with Lyme borreliosis

    Directory of Open Access Journals (Sweden)

    Katja Pruša


    Full Text Available Slovenia is an endemic area for Lyme borreliosis, a disease that affects many organic systems. Decline in cognitive abilities and emotional changes can appear in acute and chronic stage of the disease beside somatic difficulties. Early antibiotic therapy is of great importance in recovery. Attention and concentration deficits, memory deficits, impaired executive functioning, depression and other symptoms reduce work efficiency and life quality of people with Lyme borreliosis. Neuropsychological deficits can be explained with central nervous system impairment and partly also with reactive psychological factors. On account of symptomatic complexity, broad differential diagnostic and unreliable diagnostic technology neuropsychological evaluation can help to correctly diagnose and accurately treat this disease, and thus to enable appropriate cognitive rehabilitation and psychotherapeutic assistance.

  2. [The results of the pharmacological treatment of attention deficit hyperactivity disorder: evaluation with neuropsychological methods]. (United States)

    Zavadenko, N N; Suvorinova, N Iu


    To investigate the dynamics of behavioral indicators, attention and memory in children with attention deficit hyperactivity disorder (ADHD) treated with noofen (capsules 250 mg). In an open study, 50 patients were randomized to 2 equal groups: patients of group 1 were treated with noofen (15-20 mg/kg (500-700 mg) per day perorally in 2-3 doses); the control group received low doses of multivitamins. Duration of treatment was one month. The results of neuropsychological testing revealed the improvement of cognitive functions, including the indicators of self-control, sustained, directed and divided attention, acoustic-verbal memory, to the end of treatment. The initial positive changes may be the basis for obtaining better clinical results during long-term treatment.

  5. [A pediatric neuropsychological evaluation]. (United States)

    Stolarska, Urszula; Kaciński, Marek


    Pediatric neuropsychology is currently one of the most expansive fields of psychology, developing between clinical neurology and other neurosciences. This work presents the main possibilities of a pediatric neuropsychological evaluation in known clinical situations and the status of the neuropsychological profession. The necessity of evaluating the level of cognitive functioning in children from high risk groups, children with somatic, behavioural, emotional or developmental disorders was reminded. Clinical examples are described, when a neuropsychological evaluation of the child reveals important information, becoming a valuable part of the medical diagnosing process. Diagnostic methods most commonly used for assessing the level of cognitive functioning are presented, baring in mind its division into specific cognitive domains: executive functions, learning and memory, attention, visuo-motor and verbal skills. Most popular of the international and domestic IQ tests are described, including suggestions about testing children with various degrees of intellectual disability. Among the methods are tests for assessing children in age groups from 0-18. The authors described a neuropsychological interpretation of the evaluation results, including tests, behavioural observation, interviews and other diagnostic methods. Some limitations of the neuropsychological assessment methods are also mentioned, such as questionable ecological validity. the knowledge of possibilities and the necessity of the neuropsychological evaluation in children should become much more common, especially in the medical environment. The status of the neuropsychologist in Poland need a precise legal regulation.

    Full Text Available Myocardial Infarction (MI, commonly known as a Heart Attack, remains a leading cause of death throughout the world. Studies have shown that patients, who had MI, have cognitive impairment affecting attention, problem solving, memory, visuospatial, executive function and even dementia. Since cognition and emotion are integral part of the disease, there are no focused studies addressing this issue in the Indian context. Hence the present study. The objective of the study was to determine the neuropsychological deficits in patients with MI and with MI after cardiac bypass surgery. The sample consisted of 30 patients, 15 MI and 15 MI after CABG. All patients were assessed on. a battery of Neuropsychological tests and Hamilton Rating Scale for depression, The findings revealed impairment in mental speed, sustained attention, Animal Fluency Test, Phonemic Fluency Test, verbal and visual working memory, planning, response inhibition, verbal and visual learning and memory. On comparison with MI patients CABG patients showed significant deficits in Planning.

  7. Neuropsychologic deficits in children with Langerhans cell histiocytosis. (United States)

    Whitsett, S F; Kneppers, K; Coppes, M J; Egeler, R M


    Manifestations of Langerhans cell histiocytosis (LCH) in children range from only a rash, to bony lesions accompanied by pain, to major organ disease. When the central nervous system (CNS) is affected, the LCH patient may exhibit signs and symptoms of hypothalamic and pituitary dysfunction (most often resulting in diabetes insipidus or other endocrinopathies) or more global neurologic and neuropsychologic sequelae. Surprisingly, researchers have only recently begun to examine the neuropsychologic manifestations of the disease, but early findings suggest that they may, in fact, be significant in a small percentage of children with LCH. We evaluated two CNS-positive patients with LCH and long-term intermittent treatments, using extensive neuropsychologic assessments, including intellectual functioning, memory, visual-motor functioning, attention and concentration, sensory and motor performance, and gross academic achievement. Objective measures of behavior were obtained through parental report. Neuroradiologic imaging was obtained concurrently with the neuropsychologic evaluations. The neuropsychologic assessments indicated significant deficits in a number of the measured areas of functioning. Global cognitive deficiencies in full-scale IQ were identified, as were deficits in memory, attention/concentration, and perceptual-organizational capabilities. Similarities were noted in the patterns of deficits obtained with both patients, despite differences in the pathophysiology of their disease. Behavioral functioning in both children had suffered, presumably in relation to the neuropsychologic deficits. There were radiologic findings of gross cerebellar white matter damage in one patient, in addition to focal (e.g., hypothalamic) lesions in the other. LCH has an adverse impact on cognitive functions in some children with evidence of CNS involvement, and further study into the etiology, incidence, and means of remedial intervention is needed.

  8. Oculomotor deficits affect neuropsychological performance in oculomotor apraxia type 2. (United States)

    Clausi, Silvia; De Luca, Maria; Chiricozzi, Francesca R; Tedesco, Anna M; Casali, Carlo; Molinari, Marco; Leggio, Maria G


    Ataxia with oculomotor apraxia type 2 is a rare and early-disabling neurodegenerative disease, part of a subgroup of autosomal recessive cerebellar ataxia, in which oculomotor symptoms (e.g., increased saccade latency and hypometria) and executive function deficits have been described. The aim of this study was to evaluate the impact of oculomotor symptoms on cognitive performance and, in particular, over reading in 2 Italian siblings affected by ataxia with oculomotor apraxia type 2. The neuropsychological profiles and the oculomotor patterns during nonverbal and verbal tasks were recorded and analyzed. Saccadic intrusions and/or nystagmus were observed in all eye movement tasks. The neuropsychological profiles were substantially preserved, with only subtle deficits that affected visuomotor integration and attention. Reading ability decreased and became impaired. The reading scan was disturbed by saccadic intrusions and/or nystagmus. However, an ad hoc reading task demonstrated that deficits appeared only when the items that were displayed enhanced oculomotor requests. The preservation of lexical-semantic processes confirmed that the reading disability was caused by oculomotor deficits, not cognitive problems. Present findings indicate that in patients who are affected by ataxia with oculomotor apraxia type 2, performance on neuropsychological tests, especially those that require rapid performance and eye or hand-eye control, must be analyzed with respect to oculomotor components.

  14. Neuropsychological deficits in chronic schizophrenics. Relationship with symptoms and behavior. (United States)

    Dickerson, F B; Ringel, N B; Boronow, J J


    Thirty-nine hospitalized chronic schizophrenics were administered the Luria-Nebraska Neuropsychological Battery (LNNB) and the Weschler Adult Intelligence Scale-Revised when they were clinically stable. Test variables were related to Brief Psychiatric Rating Scale ratings and two behavioral measures of ward functioning, points and activities. Spearman correlations of test variables with the symptom and behavioral measures were entered into a series of median polish analyses. There was an overall significant relationship between the two sets of variables. Neuropsychological test variables that were most highly correlated with symptom/behavioral measures were LNNB Left Frontal, Memory, and Intellectual Processes scales. The positive symptoms of thought disorder and hallucinations were most consistently related to neuropsychological variables. In contrast with other findings in the literature, negative symptoms were not significantly correlated with neuropsychological performance.

  15. Qualitative syndrome analysis by neuropsychological assessment in preschoolers with attention deficit disorder with hyperactivity.

    Directory of Open Access Journals (Sweden)

    Quintanar L.


    Full Text Available The basis of this article is A. R. Luria’s conception of the qualitative approach in neuropsychology. Attention deficit disorder with hyperactivity is one of the most frequent clinical diagnoses given during preschool age. However, precise qualitative neuropsychological criteria for analysis of this clinical diagnosis do not exist and change from one approach to another. Our objective here is to propose such qualitative criteria for neuropsychological analysis of children with diagnoses of attention deficit disorder with hyperactivity at preschool age. We follow clinical methodology that is traditional for historical and cultural neuropsychology and is an alternative for the psychometrical and cognitive approach. The methodology of the study was qualitative neuropsychological assessment of the syndrome followed by detailed consideration of the types of difficulties in each case. The study analyzes mistakes and typical examples of execution of the tasks of neuropsychological qualitative assessment by regular children and by children with attention deficit disorder with hyperactivity. The results showed differences between these groups of children. The children with attention deficit disorder with hyperactivity made a lot of mistakes during assessments. Their difficulties are related to unfavorable conditions in the three functional brain blocks according to Luria’s conception. We conclude that “attention” cannot be considered the only or the main problem in children who receive this diagnosis by psychiatrists and neurologists.

  16. Academic Achievement Deficits and Their Neuropsychological Correlates in Children Born Extremely Preterm. (United States)

    Akshoomoff, Natacha; Joseph, Robert M; Taylor, H Gerry; Allred, Elizabeth N; Heeren, Timothy; OʼShea, Thomas M; Kuban, Karl C K


    The purpose of this study was to examine the risks associated with learning disabilities (LDs) in a large sample of children born extremely preterm. We predicted higher than expected rates of LD, particularly in math, and children with LD in math, reading, or both would have lower intelligence quotients (IQs) and specific patterns of neuropsychological deficits. We evaluated academic achievement, rates of LD, and their neuropsychological correlates in the Extremely Low Gestational Age Newborns (ELGANs) Study cohort of 10-year-old children born at 23 to 27 weeks gestational age. Primary analyses focused on children without intellectual disability (verbal IQ > 70 and nonverbal IQ > 70; N = 668). Low achievement was defined as a standard score ≤85 on the reading or math measures. The risk of low math achievement scores (27%) was 1.5 times higher than the risk of low reading achievement scores (17%). Children were classified as having LD based on low achievement criteria in reading only (RD, 6.4% of sample), math only (MD, 16.2%), both reading and math (RD/MD, 8.3%), or no reading or math disabilities (No LD, 69.1%). Although all 3 LD groups had multiple neuropsychological weaknesses compared with the No LD group, the RD and MD groups had different patterns of neuropsychological impairment. These children from the ELGAN cohort had higher than expected rates of LD, particularly in mathematics, even after taking socioeconomic status into consideration. These results indicate specific cognitive weaknesses that differ between extremely preterm children with RD and MD.

  17. Detailed neuropsychological evaluation in a patient with Floating Harbor syndrome. (United States)

    Pouliquen, D; Goldenberg, A; Hannequin, D; Lecointre, C; Lechevallier, J; Cormier-Daire, V; Martinaud, O


    The Floating Harbor syndrome is a rare genetic disease characterized by a triad of clinical signs: specific dysmorphic facial features, short stature with delayed bone age, and language and speech disorders. These signs are, in most cases, associated with borderline normal intelligence to moderate delay concerning intellectual functioning. We report an extensive neuropsychological evaluation for an adult female patient and show, in particular, a severe visuospatial impairment. We discuss this deficit in the light of the previous reported cases and suggest that visuospatial abilities should be explored more systematically.

  18. The Combined Effect of Neuropsychological and Neuropathological Deficits on Instrumental Activities of Daily Living in Older Adults: a Systematic Review. (United States)

    Overdorp, Eduard J; Kessels, Roy P C; Claassen, Jurgen A; Oosterman, Joukje M


    To date, studies have consistently demonstrated associations between either neuropsychological deficits or neuroanatomical changes and instrumental activities of daily living (IADL) in aging. Only a limited number of studies have evaluated morphological brain changes and neuropsychological test performance concurrently in relation to IADL in this population. As a result, it remains largely unknown whether these factors independently predict functional outcome. The current systematic review intended to address this lack of information by reviewing the literature on older adults, incorporating studies that examined e.g., normal aging, but also stroke or dementia patients. A comprehensive search of databases (Pubmed, Embase, Medline, Web of Science, PsycINFO) and reference lists was performed, focusing on papers in the English language that examined the combined effect of neuropsychological and neuroanatomical factors on IADL in samples of adults with an average age above 50. In total, 58 potential articles were identified; 20 were included in the review. The results show that especially neuropsychological variables (primarily memory and executive functions) independently predict IADL. Although some unique predictive value of brain morphological changes, such as hippocampal atrophy, was found, support for the importance of white matter changes was limited. However, the results of the studies reviewed are diverse, and appear to be at least partially determined by the variables included. For example, studies were less likely to find an independent effect of cognition if they solely employed a cognitive screening instrument. This indicates that a structured examination of neuroanatomical and neuropsychological correlates of IADL in different patient populations is warranted.

  19. Childhood obstructive sleep apnea associates with neuropsychological deficits and neuronal brain injury.

    Directory of Open Access Journals (Sweden)

    Ann C Halbower


    Full Text Available Childhood obstructive sleep apnea (OSA is associated with neuropsychological deficits of memory, learning, and executive function. There is no evidence of neuronal brain injury in children with OSA. We hypothesized that childhood OSA is associated with neuropsychological performance dysfunction, and with neuronal metabolite alterations in the brain, indicative of neuronal injury in areas corresponding to neuropsychological function.We conducted a cross-sectional study of 31 children (19 with OSA and 12 healthy controls, aged 6-16 y group-matched by age, ethnicity, gender, and socioeconomic status. Participants underwent polysomnography and neuropsychological assessments. Proton magnetic resonance spectroscopic imaging was performed on a subset of children with OSA and on matched controls. Neuropsychological test scores and mean neuronal metabolite ratios of target brain areas were compared. Relative to controls, children with severe OSA had significant deficits in IQ and executive functions (verbal working memory and verbal fluency. Children with OSA demonstrated decreases of the mean neuronal metabolite ratio N-acetyl aspartate/choline in the left hippocampus (controls: 1.29, standard deviation [SD] 0.21; OSA: 0.91, SD 0.05; p = 0.001 and right frontal cortex (controls: 2.2, SD 0.4; OSA: 1.6, SD 0.4; p = 0.03.Childhood OSA is associated with deficits of IQ and executive function and also with possible neuronal injury in the hippocampus and frontal cortex. We speculate that untreated childhood OSA could permanently alter a developing child's cognitive potential.

  20. Learning disabilities: the need for neuropsychological evaluation. (United States)

    Silver, Cheryl H; Ruff, Ronald M; Iverson, Grant L; Barth, Jeffrey T; Broshek, Donna K; Bush, Shane S; Koffler, Sandra P; Reynolds, Cecil R


    A learning disability (LD) is a neurobiological disorder that presents as a serious difficulty with reading, arithmetic, and/or written expression that is unexpected, given the individual's intellectual ability. A learning disability is not an emotional disorder nor is it caused by an emotional disorder. If inadequately or improperly evaluated, a learning disability has the potential to impact an individual's functioning adversely and produce functional impairment in multiple life domains. When a learning disability is suspected, an evaluation of neuropsychological abilities is necessary to determine the source of the difficulty as well as the areas of neurocognitive strength that can serve as a foundation for compensatory strategies and treatment options.

    Brodsky, Kimberly; Willcutt, Erik G.; Davalos, Deana B.; Ross, Randal G.


    Background: Attention-deficit/hyperactivity disorder (ADHD) and childhood-onset psychosis (COP) are chronic, heterogeneous disorders with symptoms that frequently co-occur, but the etiology of their comorbidity is unknown. Studies of each disorder indicate that both ADHD and COP are associated with a range of neuropsychological weaknesses, but few…

  2. Is Insomnia Associated with Deficits in Neuropsychological Functioning? Evidence from a Population-Based Study (United States)

    Goldman-Mellor, Sidra; Caspi, Avshalom; Gregory, Alice M.; Harrington, HonaLee; Poulton, Richie; Moffitt, Terrie E.


    Study Objectives: People with insomnia complain of cognitive deficits in daily life. Results from empirical studies examining associations between insomnia and cognitive impairment, however, are mixed. Research is needed that compares treatment-seeking and community-based insomnia study samples, measures subjective as well as objective cognitive functioning, and considers participants' pre-insomnia cognitive function. Design and Participants: We used data from the Dunedin Study, a representative birth cohort of 1,037 individuals, to examine whether insomnia in early midlife was associated with subjective and objective cognitive functioning. We also tested whether individuals with insomnia who reported seeking treatment for their sleep problems (treatment-seekers) showed greater impairment than other individuals with insomnia (non-treatment-seekers). The role of key confounders, including childhood cognitive ability and comorbid health conditions, was evaluated. Measurements: Insomnia was diagnosed at age 38 according to DSM-IV criteria. Objective neuropsychological assessments at age 38 included the WAIS-IV IQ test, the Wechsler Memory Scale, and the Trail-Making Test. Childhood cognitive functioning was assessed using the Wechsler Intelligence Scale for Children-Revised (WISC-R). Results: A total of 949 cohort members were assessed for insomnia symptoms and other study measures at age 38. Although cohort members with insomnia (n = 186, 19.6%) had greater subjective cognitive impairment than their peers at age 38, they did not exhibit greater objective impairment on formal testing. Treatment-seekers, however, exhibited significant objective impairment compared to non-treatment-seekers. Controlling for comorbidity, daytime impairment, and medications slightly decreased this association. Childhood cognitive deficits antedated the adult cognitive deficits of treatment-seekers. Conclusions: Links between insomnia and cognitive impairment may be strongest among

  3. Pre- and Perinatal Risk for Attention-Deficit Hyperactivity Disorder: Does Neuropsychological Weakness Explain the Link? (United States)

    Wiggs, Kelsey; Elmore, Alexis L; Nigg, Joel T; Nikolas, Molly A


    Etiological investigations of attention-deficit hyperactivity disorder (ADHD) and disruptive behavior problems support multiple causal pathways, including involvement of pre- and perinatal risk factors. Because these risks occur early in life, well before observable ADHD and externalizing symptoms emerge, the relation between risk and symptoms may be mediated by neurodevelopmental effects that manifest later in neuropsychological functioning. However, potential dissociable effects of pre/perinatal risk elements on ADHD and familial confounds must also be considered to test alternative hypotheses. 498 youth aged 6-17 years (55.0 % male) completed a multi-stage, multi-informant assessment including parent and teacher symptom reports of symptoms and parent ratings of pre/perinatal health risk indicators. Youth completed a neuropsychological testing battery. Multiple mediation models examined direct effects of pre- and perinatal health risk on ADHD and other disruptive behavior disorder symptoms and indirect effects via neuropsychological functioning. Parental ADHD symptoms and externalizing status was covaried to control for potential familial effects. Effects of prenatal substance exposure on inattention were mediated by memory span and temporal processing deficits. Further, effects of perinatal health risk on inattention, hyperactivity-impulsivity, and ODD were mediated by deficits in response variability and temporal processing. Further, maternal health risks during pregnancy appeared to exert direct rather than indirect effects on outcomes. Results suggest that after controlling for familial relatedness of ADHD between parent and child, early developmental health risks may influence ADHD via effects on neuropsychological processes underpinning the disorder.

    Alternating hemiplegic of childhood is a predominantly sporadic neurodevelopmental syndrome of uncertain etiology, characterized by alternating transient attacks of hemiplegia. Additional features include tonic fits, dystonic posturing, ocular motor abnormalities and deficits in cognitive functioning. A girl of 7 years-old with alternating hemiplegic of childhood. The first symptoms debut at 17 months of age in the form of lower limb weakness, migraine, nystagmus and hemiplegic crisis alternating both hemibodies. We administrate the Wechsler Intelligence Scale for Children IV (WISC-IV), the Conners Continuous Performance Test II (CPT-II), the Conners scales for parents (CPRS-48) and teachers (CTRS-28) and the Behavior Rating Inventory Executive Function (BRIEF). In our study we found deficits in sustained attention, reduced speed of information processing, and difficulties in understanding, speaking and working memory. In addition, parents and teachers reported behavioral disturbances, difficulties inhibition capability, in self-control and in regulating emotions.

  6. Neuropsychological deficits associated with cannabis use in young adults. (United States)

    Grant, Jon E; Chamberlain, Samuel R; Schreiber, Liana; Odlaug, Brian L


    Cannabis is the most widely used illicit substance and has been associated with cognitive impairment. It is unclear whether such impairment can occur in the absence of potential confounding influences of co-morbid axis-I disorders and use of other illicit substances. Young adult volunteers (18-29 years) were recruited from the general community on the basis of having no axis-I disorders or history of illicit substance use other than cannabis use. Subjects were then grouped according to presence or absence of cannabis use (>1 time/week over past 12 months). Cognition was compared between groups using selected paradigms from the CANTAB. Cannabis users (N=16) and controls (N=214) did not differ significantly on salient demographic characteristics. Compared to controls, cannabis users showed significant impairments on quality of decision-making (Cambridge Gamble task), and executive planning (One Touch Stockings of Cambridge task). Response inhibition, spatial working memory, and sustained attention were intact. This study identified cognitive deficits in cannabis users even in the absence of axis-I disorders and a history of using other illicit drugs. Future work should use longitudinal designs to track whether these deficits predate cannabis use or are due to its consumption. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

  7. Ecological neuropsychology: an alternative to the deficit model for conceptualizing and serving students with learning disabilities. (United States)

    D'Amato, Rik Carl; Crepeau-Hobson, Franci; Huang, Leesa V; Geil, Molly


    The present paper contends that children with learning disabilities are better served when assessment and intervention are conceptualized within an ecological neuropsychology perspective than within the traditional deficit model perspective, which is the predominant approach to intervention in medical and educational settings. The deficit method conceptualizes problems as within the child, and the major consequence of this approach is that little time is spent analyzing the learning environment or other systems that might impact the child's ability to be successful in an academic setting. Therefore, rehabilitation efforts have had limited success. In contrast, ecological neuropsychology is a strength-based approach that considers the child, as well as the systems within which he/she interacts, when assessing, diagnosing, and intervening with students who are experiencing learning difficulties.

  8. Neuropsychological and neurophysiological approaches to study of variants of Attention Deficit Hyperactivity Disorder

    Directory of Open Access Journals (Sweden)

    Matveyeva E. Yu.


    Full Text Available The present review carries out analysis of empirical studies concerning neuropsychological and neurophysiological mechanisms of Attention Deficit Hyperactivity Disorder (ADHD. The current data, regarding malfunctions of brain systems at various levels of aetiopathogenesis (genetic, neurotrasmitting, functioning of separate brain structure, are discussed. The article regards the character of deficit in various components of psychic activity in people with ADHD, namely, executive functions and temporary storage (working memory, activating and neurodynamic components of activity, separate operational characteristics, and motivational impairments of patients with ADHD. The possibility of disclosing some clinical variants of the ADHD syndrome, differing in mechanisms, is also discussed in the article.

  9. Neuropsychological basic deficits in preschoolers at risk for ADHD: a meta-analysis. (United States)

    Pauli-Pott, Ursula; Becker, Katja


    Widely accepted neuropsychological theories on attention deficit hyperactivity disorder (ADHD) assume that the complex symptoms of the disease arise from developmentally preceding neuropsychological basic deficits. These deficits in executive functions and delay aversion are presumed to emerge in the preschool period. The corresponding normative developmental processes include phases of relative stability and rapid change. These non-linear developmental processes might have implications for concurrent and predictive associations between basic deficits and ADHD symptoms. To derive a description of the nature and strength of these associations, a meta-analysis was conducted. It is assumed that weighted mean effect sizes differ between basic deficits and depend on age. The meta-analysis included 25 articles (n=3005 children) in which associations between assessments of basic deficits (i.e. response inhibition, interference control, delay aversion, working memory, flexibility, and vigilance/arousal) in the preschool period and concurrent or subsequent ADHD symptoms or diagnosis of ADHD had been analyzed. For response inhibition and delay aversion, mean effect sizes were of medium to large magnitude while the mean effect size for working memory was small. Meta-regression analyses revealed that effect sizes of delay aversion tasks significantly decreased with increasing age while effect sizes of interference control tasks and Continuous Performance Tests (CPTs) significantly increased. Depending on the normative maturational course of each skill, time windows might exist that allow for a more or less valid assessment of a specific deficit. In future research these time windows might help to describe early developing forms of ADHD and to identify children at risk. Copyright © 2011 Elsevier Ltd. All rights reserved.

  10. Social Cognition Deficits: Current Position and Future Directions for Neuropsychological Interventions in Cerebrovascular Disease. (United States)

    Njomboro, Progress


    Neuropsychological assessments of cognitive dysfunction in cerebrovascular illness commonly target basic cognitive functions involving aspects of memory, attention, language, praxis, and number processing. Here, I highlight the clinical importance of often-neglected social cognition functions. These functions recruit a widely distributed neural network, making them vulnerable in most cerebrovascular diseases. Sociocognitive deficits underlie most of the problematic social conduct observed in patients and are associated with more negative clinical outcomes (compared to nonsocial cognitive deficits). In clinical settings, social cognition deficits are normally gleaned from collateral information from caregivers or from indirect inferences made from patients' performance on standard nonsocial cognitive tests. Information from these sources is however inadequate. I discuss key social cognition functions, focusing initially on deficits in emotion perception and theory of mind, two areas that have gained sizeable attention in neuroscientific research, and then extend the discussion into relatively new, less covered but crucial functions involving empathic behaviour, social awareness, social judgements, and social decision making. These functions are frequently impaired following neurological change. At present, a wide range of psychometrically robust social cognition tests is available, and this review also makes the case for their inclusion in neuropsychological assessments.

  11. Neuropsychology of Early-Treated Phenylketonuria: Specific Executive Function Deficits. (United States)

  15. [Neuropsychological evaluation and psychopathology of multiple sclerosis]. (United States)

    Defer, G


    Cognitive and psychiatric disorders have long been described in MS. However, these symptoms were only well evaluated starting about fifteen years ago. More recently, there has been renewed interest in cognitive and psychiatric assessment in MS, especially due to the emergence of new therapies for the disease. Psychiatric symptoms mainly include depression and anxiety. Depression is generally moderate, but there is a risk of suicide that is clearly higher than in the general population. Depression is not correlated with the duration of symptoms, type of disease or level of disability. Mild elation and pathological laughing and crying can be associated and are more frequent in case of severe disease. Bipolar affective disorders and alexithymia are more rare. The question of premorbid personality has been questioned for depression but not confirmed. It has been suspected for bipolar affective disorders. Cognitive disorders are observed in 40 to 65% of the cases at any period of the disease. They mainly include an impairment of working and long-term memory, executive functions and attention whereas global intellectual efficiency is impaired later. While cognitive disorders can be observed early in the course of the disease, there is no correlation with the level of disability or duration of the disease. Progressive MS and especially secondary progressive then primary progressive forms are more subject to cognitive deficits than relapsing remitting MS. For a similar cognitive impairment, progression could be a negative factor for the disease course. Cognitive and psychiatric assessment of patients can be discussed on the basis of why, how and when. Psychiatric assessment is not particularly difficult when there are psychiatric complaints, but cognitive assessment should be explained to the patients and justified when there is no complaint. However, detection of cognitive deficits would lead to better patient management. Psychiatric assessment will mainly use controlled

    The authors performed meta-analyses of randomized controlled trials to examine the effects of cognitive training on attention-deficit/hyperactivity disorder (ADHD) symptoms, neuropsychological deficits, and academic skills in children/adolescents with ADHD. The authors searched Pubmed, Ovid, Web of Science, ERIC, and CINAHAL databases through May 18, 2014. Data were aggregated using random-effects models. Studies were evaluated with the Cochrane risk of bias tool. Sixteen of 695 nonduplicate records were analyzed (759 children with ADHD). When all types of training were considered together, there were significant effects on total ADHD (standardized mean difference [SMD] = 0.37, 95% CI = 0.09-0.66) and inattentive symptoms (SMD = 0.47, 95% CI = 0.14-0.80) for reports by raters most proximal to the treatment setting (i.e., typically unblinded). These figures decreased substantially when the outcomes were provided by probably blinded raters (ADHD total: SMD = 0.20, 95% CI = 0.01-0.40; inattention: SMD = 0.32, 95% CI = -0.01 to 0.66). Effects on hyperactivity/impulsivity symptoms were not significant. There were significant effects on laboratory tests of working memory (verbal: SMD = 0.52, 95% CI = 0.24-0.80; visual: SMD = 0.47, 95% CI = 0.23-0.70) and parent ratings of executive function (SMD = 0.35, 95% CI = 0.08-0.61). Effects on academic performance were not statistically significant. There were no effects of working memory training, specifically on ADHD symptoms. Interventions targeting multiple neuropsychological deficits had large effects on ADHD symptoms rated by most proximal assessors (SMD = 0.79, 95% CI = 0.46-1.12). Despite improving working memory performance, cognitive training had limited effects on ADHD symptoms according to assessments based on blinded measures. Approaches targeting multiple neuropsychological processes may optimize the transfer of effects from cognitive deficits to clinical symptoms. Copyright © 2015 American Academy

  17. Neuropsychological deficits associated with heavy prenatal alcohol exposure are not exacerbated by ADHD. (United States)

    Neuropsychological functioning of individuals with attention-deficit/hyperactivity disorder (ADHD) or heavy prenatal alcohol exposure has been well documented independently. This study examined the interaction between both factors on cognitive performance in children. As part of a multisite study, 344 children (8-16 y, M = 12.28, SD = 2.52) completed a comprehensive neuropsychological battery. Four subject groups were tested: children with histories of heavy prenatal alcohol exposure (AE) and ADHD (AE+, n = 90), alcohol-exposed without ADHD, (AE-, n = 38), nonexposed with ADHD (ADHD, n = 80), and nonexposed without ADHD (CON, n = 136). Separate 2(AE) × 2(ADHD) MANCOVAs revealed significant main and interactive effects of ADHD and AE on overall WISC-IV, D-KEFS, and CANTAB performance. Individual ANOVAs revealed significant interactions on 2 WISC-IV indices [Verbal Comprehension (VCI), Perceptual Reasoning (PRI)], and four D-KEFS and CANTAB subtests [Design Fluency, Verbal Fluency, Trail Making, Spatial Working Memory]. Follow-up analyses demonstrated no difference between AE+ and AE- groups on these measures. The combined AE+/- group demonstrated more severe impairment than the ADHD group on VCI and PRI, but there were no other differences between clinical groups. These results support a combined AE+/- group for neuropsychological research and indicate that, in some cases, the neuropsychological effects seen in ADHD are altered by prenatal alcohol exposure. The effects of alcohol exposure on verbal comprehension and perceptual reasoning were greater than those related to having ADHD without alcohol exposure, although both conditions independently resulted in cognitive impairment compared to controls. Clinically, these findings demonstrate task-dependent patterns of impairment across clinical disorders. PsycINFO Database Record (c) 2013 APA, all rights reserved.

  19. The Reality Monitoring Deficit as a Common Neuropsychological Correlate of Schizophrenic and Affective Psychosis

    Directory of Open Access Journals (Sweden)

    Enrico Smeraldi


    Full Text Available For many decades, Neuropsychological functioning has been a key point in the study of psychotic disorders. The main aim of these studies is to give a description of the neurocognitive “profile” of schizophrenia, with only little attention being paid to the common and discriminating features of different psychotic disorders. Recent studies support the hypothesis that patients affected by psychiatric disorders with psychotic symptoms have specific abnormalities of reality testing of ongoing perception, which become evident with source monitoring task. Ninety-eight patients and 50 controls were studied. Patients were divided by diagnosis and previous history of psychotic features and were administered Source Monitoring Task to test reality testing of ongoing perception. Frequencies of correct and false attributions were recorded. To obtain measures of observer sensitivity and response biases, a signal detection analysis was performed. Aims: Studying neuropsychological correlate of psychosis in euthymic mood disordered patients and patients with schizophrenia with or without delusions. Results: Patients with psychotic features use more lax criteria in evaluating self-generated, but not perceived stimuli compared to patients without psychotic features. Conclusions: Our findings support the hypothesis of selective biases in reality monitoring as neuropsychological correlates of psychosis.

  20. Reconsidering "inattention" in attention-deficit hyperactivity disorder: implications for neuropsychological assessment and intervention. (United States)

    Carmichael, Jessica A; Kubas, Hanna A; Carlson, Helen L; Fitzer, Kim R; Wilcox, Gabrielle; Lemay, Jean-François; Bray, Signe; MacMaster, Frank P; Hale, James B


    Attention-deficit hyperactivity disorder (ADHD) does not exist. This explicit statement needs elucidation of course given ADHD is a common neurodevelopmental disorder, but it provides the reader with the impetus to reconsider long-held beliefs about this condition and its treatment. Surely, there is a disorder called ADHD from which this thesis is framed, but primary attention and hyperactivity-impulsivity problems are mediated by different albeit interrelated brain systems. Like many neurodevelopmental disorders (e.g., learning disabilities, autism spectrum disorder), the medical and psychological professions have used a single, large inclusive ADHD diagnostic category to represent children with different etiologies for their overt symptoms. Despite neurobiological differences among children diagnosed with ADHD, the clinical position that attention-deficit or primary attention problems are sufficient for ADHD identification undermines clinical practice. This commonly accepted dubious position not only undermines the diagnostic utility of our neuropsychological measures, but it attenuates treatment effects as well. Supported with evidence from our ongoing ADHD research program, this data-based review will support these contentions and provide implications for diagnosis and treatment of children with attention problems.

  1. Neuropsychological deficits in the prodromal phase and course of an early-onset schizophrenia. A case report. (United States)

    Puetz, Vanessa; Günther, Thomas; Kahraman-Lanzerath, Berrak; Herpertz-Dahlmann, Beate; Konrad, Kerstin


    Although clear advances have been achieved in the study of early-onset schizophrenia (EOS), little is known to date about premorbid and prodromal neuropsychological functioning in EOS. Here, we report on a case of an adolescent male with EOS who underwent neuropsychological testing before and after illness onset. Marked cognitive deficits in the domains of attention, set-shifting, and verbal memory were present both pre-onset and during the course of schizophrenia, though only deficits in verbal memory persisted after illness-onset and antipsychotic treatment. The findings of this case study suggest that impairments in the verbal memory domain are particularly prominent symptoms of cognitive impairment in prodromal EOS and persist in the course of the disorder, which further demonstrates the difficult clinical situation of adequate schooling opportunities for adolescent patients with EOS.

  2. Auditory and cognitive deficits associated with acquired amusia after stroke: a magnetoencephalography and neuropsychological follow-up study.

    Teppo Särkämö


    Full Text Available Acquired amusia is a common disorder after damage to the middle cerebral artery (MCA territory. However, its neurocognitive mechanisms, especially the relative contribution of perceptual and cognitive factors, are still unclear. We studied cognitive and auditory processing in the amusic brain by performing neuropsychological testing as well as magnetoencephalography (MEG measurements of frequency and duration discrimination using magnetic mismatch negativity (MMNm recordings. Fifty-three patients with a left (n = 24 or right (n = 29 hemisphere MCA stroke (MRI verified were investigated 1 week, 3 months, and 6 months after the stroke. Amusia was evaluated using the Montreal Battery of Evaluation of Amusia (MBEA. We found that amusia caused by right hemisphere damage (RHD, especially to temporal and frontal areas, was more severe than amusia caused by left hemisphere damage (LHD. Furthermore, the severity of amusia was found to correlate with weaker frequency MMNm responses only in amusic RHD patients. Additionally, within the RHD subgroup, the amusic patients who had damage to the auditory cortex (AC showed worse recovery on the MBEA as well as weaker MMNm responses throughout the 6-month follow-up than the non-amusic patients or the amusic patients without AC damage. Furthermore, the amusic patients both with and without AC damage performed worse than the non-amusic patients on tests of working memory, attention, and cognitive flexibility. These findings suggest domain-general cognitive deficits to be the primary mechanism underlying amusia without AC damage whereas amusia with AC damage is associated with both auditory and cognitive deficits.

    We performed meta-analyses of randomized controlled trials to examine the effects of neurofeedback on attention-deficit/hyperactivity disorder (ADHD) symptoms and neuropsychological deficits in children and adolescents with ADHD. We searched PubMed, Ovid, Web of Science, ERIC, and CINAHAL through August 30, 2015. Random-effects models were employed. Studies were evaluated with the Cochrane Risk of Bias tool. We included 13 trials (520 participants with ADHD). Significant effects were found on ADHD symptoms rated by assessors most proximal to the treatment setting, that is, the least blinded outcome measure (standardized mean difference [SMD]: ADHD total symptoms = 0.35, 95% CI = 0.11-0.59; inattention = 0.36, 95% CI = 0.09-0.63; hyperactivity/impulsivity = 0.26, 95% CI = 0.08-0.43). Effects were not significant when probably blinded ratings were the outcome or in trials with active/sham controls. Results were similar when only frequency band training trials, the most common neurofeedback approach, were analyzed separately. Effects on laboratory measures of inhibition (SMD = 0.30, 95% CI = -0.10 to 0.70) and attention (SMD = 0.13, 95% CI = -0.09 to 0.36) were not significant. Only 4 studies directly assessed whether learning occurred after neurofeedback training. The risk of bias was unclear for many Cochrane Risk of Bias domains in most studies. Evidence from well-controlled trials with probably blinded outcomes currently fails to support neurofeedback as an effective treatment for ADHD. Future efforts should focus on implementing standard neurofeedback protocols, ensuring learning, and optimizing clinically relevant transfer.

  6. Self-reported symptoms of attention-deficit/hyperactivity disorder: rate of endorsement and association with neuropsychological performance in an adult psychiatric sample. (United States)

    Schneider, Brooke C; Thoering, Teresa; Cludius, Barbara; Moritz, Steffen


    The lack of specificity of attention-deficit/hyperactivity disorder (ADHD) symptoms represents a diagnostic challenge, especially when assessing psychiatric patients reporting a wide range of complaints. Rate of endorsement of ADHD symptoms, and their association with neuropsychological performance, was examined in a psychiatric sample of 71 adults, who had been referred for a neuropsychological evaluation. Patients completed two self-report measures of ADHD symptoms, the ADHD Self-Report Scale (ADHD-SR) and the Wender Utah Rating Scale-Short Form, as well as measures of attention, executive functioning, visuoconstructional ability, and verbal learning and memory. On the ADHD-SR, 74.6% of the sample met the cutoff for inattention or hyperactivity, while 81.7% met the cutoff for impulsivity. Neuropsychological performance was weakly associated with self-reported symptoms. Our results suggest that psychiatric patients commonly report symptoms of inattention, hyperactivity, and impulsivity. Assessment utilizing multiple sources is necessary to confirm whether self-reported symptoms are indicative of ADHD or reflect other causes. © The Author 2015. Published by Oxford University Press.

  7. Cognitive Deficits in Chronic Stroke Patients: Neuropsychological Assessment, Depression, and Self-Reports

    Directory of Open Access Journals (Sweden)

    Arne E. Nakling


    Full Text Available Background: Following stroke, clinicians are challenged to detect and untangle symptoms of cognitive dysfunction and mood disorders. Additionally, they need to evaluate the informative value of self-reports to identify patients in need of further attendance. Aims: To examine the association between neuropsychological measures, symptoms of depression, and self-reported cognitive function. Methods: One-hundred and five chronic stroke patients underwent assessment covering 6 cognitive domains and answered the Hospital Anxiety and Depression Scale and the Memory and Thinking Scale from the Stroke Impact Scale 1 year after stroke. Age and gender difference in cognitive impairment were examined; linear regression was used to predict depression scores. Sensitivity and specificity analyses were used to validate self-reported functioning against performance on cognitive tests. Results: Cognitive impairment was observed in 60% of the patients in at least 1 cognitive domain. Cognitive performance was associated with symptoms of depression as well as with self-reported cognitive function. The final analyses revealed low sensitivity and specificity for the Memory and Thinking subscale from the Stroke Impact Scale. Conclusion: Cognitive impairment occurs frequently even in patients in a chronic phase after stroke and predicts symptoms of depression. Using the Stroke Impact Scale, clinicians should be aware of low sensitivity of self-reported cognitive function.

  8. Cognitive functioning and adjudicative competence: defendants referred for neuropsychological evaluation in a psychiatric inpatient setting. (United States)

    Arredondo, Beth C; Marcopulos, Bernice A; Brand, Jesse G; Campbell, Kristen T; Kent, Julie-Ann


    A paucity of peer-reviewed research exists regarding the relation between cognitive functioning and adjudicative competence, despite increasing awareness of cognitive deficits associated with serious mental illness. This retrospective study sought to add to and expand upon existing research by considering performance validity and court determinations of competence, when available. We compared demographic and cognitive variables of a group of defendants with presumed valid testing admitted to an inpatient psychiatric facility for evaluation of adjudicative competence and referred for neuropsychological evaluation (n = 45) and compared individuals determined by the evaluator and/or the court to be competent (n = 30) and incompetent (n = 15). Defendants who were incompetent were more likely to be diagnosed with a cognitive disorder, with a medium effect size. There was a difference in tests of immediate and delayed memory as measured by the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), with medium to large effects, and high delayed memory scores were helpful in ruling out incompetence (Negative predictive power = 85.71%). These results provide support for the relationship between cognitive functioning and trial competence, particularly at high and low levels of performance.

  9. Attention Deficit Hyperactivity Disorder in Children With Sickle Cell Disease Referred for an Evaluation. (United States)

    Acquazzino, Melissa A; Miller, Meghan; Myrvik, Matthew; Newby, Robert; Scott, John Paul


    Neuropsychological deficits, including difficulties with attention, are well described in children with sickle cell disease (SCD). Very little is known about attention deficit hyperactivity disorder (ADHD) in children with SCD. The objective of this study was to determine the proportion of ADHD in children with SCD referred for neuropsychological evaluation. This prospective, cross-sectional study included patients (age, 4 to 18 y) with SCD and completion of a neuropsychological evaluation between December 2013 and March 2016. Patients were referred for neuropsychological evaluation because of concern regarding school performance, development, and/or behavior. The diagnosis of ADHD was made by a neuropsychologist on the basis of the diagnostic criteria in the Diagnostic Statistical Manual-Fourth or Fifth Editions. ADHD medication usage rate was obtained by medical record review. Of the 89 patients with SCD referred for neuropsychological evaluation, 25% (95% confidence interval, 16%-35%) met diagnostic criteria for ADHD. Only 21% of the patients with SCD and ADHD were prescribed an ADHD medication. Our study supports routine ADHD screening in children with SCD who have poor school performance or behavioral concerns. Despite the benefits of pharmacologic treatment, the majority of patients with SCD and ADHD did not receive a medication for management of their ADHD.

    Reduced IQ, learning difficulties and poor school performance have been reported in small-for-gestational-age (SGA) subjects. However, few studies include a comprehensive neuropsychological assessment. Our aim was to study neuropsychological functioning in young adults born SGA at term. A comprehensive neuropsychological test battery was administered to 58 SGA subjects (birth weight SGA controls (birth weight ≥10th centile). The SGA group obtained significantly (p SGA controls and showed higher risk of obtaining scores below -1.5 SD on the memory domain (odds ratio = 13.3, 95% confidence interval: 1.57, 112.47). At a subtest level, the SGA group obtained lower scores on most neuropsychological tests, with significant differences on 6 of 46 measures: the Trail Making Test 3 (letter sequencing), the Wechsler Memory Scale mental control and the auditory immediate memory scale, the Design Fluency, the Stroop 3 (inhibition) and the Visual Motor Integration (VMI) motor coordination subtest. Young adults born SGA score more poorly on neuropsychological tests compared with non-SGA controls. Differences were modest, with more significant differences in the memory domain.

    To investigate neuropsychological and neurobehavioral outcome in children with arterial ischemic stroke (AIS). Childhood stroke can have consequences on motor, cognitive, and behavioral development. We present a cross-sectional study of neuropsychological and neurobehavioral outcome at least one year poststroke in a uniquely homogeneous sample of children who had experienced AIS. Forty-nine children with AIS aged 6 to 18 years were recruited from a specialist clinic. Neuropsychological measures of intelligence, reading comprehension, attention, and executive function were administered. A triangulation of data collection included questionnaires completed by the children, their parents, and teachers, rating behavior, executive functions, and emotions. Focal neuropsychological vulnerabilities in attention (response inhibition and dual attention) and executive function were found, beyond general intellectual functioning, irrespective of hemispheric side of stroke. Difficulties with emotional and behavioral regulation were also found. Consistent with an "early plasticity" hypothesis, earlier age of stroke was associated with better performance on measures of executive function. A significant proportion of children poststroke are at long-term risk of difficulties with emotional regulation, executive function, and attention. Data also suggest that executive functions are represented in widespread networks in the developing brain and are vulnerable to unilateral injury.

  16. Gender Differences in the Behavioral Symptoms and Neuropsychological Performance of Patients with Attention-Deficit/Hyperactivity Disorder Treated with Methylphenidate: A Two-Year Follow-up Study. (United States)

    Wang, Liang-Jen; Chen, Chih-Ken; Huang, Yu-Shu


    This study investigated the gender differences in behavioral symptoms, as rated by various informants, and in neuropsychological performance, among patients with attention-deficit/hyperactivity disorder (ADHD) treated with methylphenidate during 24 months in a clinical setting. Study participants comprised 128 boys (mean age: 13.2±2.4 years) and 26 girls (mean age: 12.8±1.0 years) with ADHD. All patients were prescribed short-acting oral methylphenidate, taken two or three times daily; each dose ranged between 0.3 and 1.0 mg/kg. At the baseline and 6, 12, 18, and 24 months later, behavioral symptoms were evaluated using the parent and teacher forms of the Swanson, Nolan, and Pelham Version IV (SNAP-IV) scale for ADHD and the ADHD Rating Scale (completed by a child psychiatrist). In addition, neuropsychological function was assessed using the Test of Variables of Attention (TOVA) at each interval. Although both the boys and girls exhibited a significant decrease in the ADHD symptoms observed by parents and clinicians, the girls improved more than the boys did. Based on the teacher reports, neither the boys nor the girls exhibited significant decreases in ADHD symptoms. The symptoms rated by teachers were more severe in the boys than in the girls throughout the first 12 months; however, the gender difference lessened after 12 months. Based on the TOVA assessment, a composite score (containing response time, response time variability, and ADHD score obtained using the TOVA) did not indicate differences between genders. However, another composite score (containing omission errors, commission errors, and response sensitivity) suggested significant improvement only in the boys. The results suggested that according to a longitudinal follow-up, behavioral and neuropsychological changes among patients with ADHD might differ between genders. Gathering multidimensional information from patients with ADHD is essential in determining how gender modifies the functional

  18. Comparison of neuropsychological performances and behavioral patterns of children with attention deficit hyperactivity disorder and severe mood dysregulation. (United States)

    Uran, Pınar; Kılıç, Birim Günay


    We aimed to investigate the similarities and differences in neuropsychological test performance, demographic features and behavioral patterns of children and adolescents with the attention deficit hyperactivity disorder combined type (ADHD-C), and the severe mood dysregulation (SMD). Study includes 112 children: 67 with ADHD-C, 24 with SMD and 21 healthy controls. These groups were identified by using the schedule for affective disorders, and schizophrenia for the school-age children-present and lifetime version (KSADS-PL) and the K-SADS-PL-SMD Module. Conners' Parent and Teacher Rating Scale-revised long form (CPRS-R:L and CTRS-R:L) and neuropsychological tests were administered to the research groups. ADHD-C group's performances in Wisconsin Card Sorting Test, Trail Making Test, Stroop Test TBAG form and Controlled Oral Word Association Test were significantly poorer than the control group's performances (p Performance of the SMD group was only descriptively intermediate between performances of the ADHD-C and control group. In the "Oppositional", "Hyperactivity", "Social Problems", "Impulsive", "Emotional Lability" and "Conners' Global Index" subscales of CPRS-R:L, the average scores of the SMD group were significantly higher than the ADHD-C and control group's average scores (p < 0.05). ADHD-C group (but not SMD) could be significantly differentiated from healthy controls with the neuropsychological tests used. SMD group could be differentiated from the ADHD-C and healthy control groups with CPRS-R:L; i.e., ADHD-C versus SMD could be differentiated at the behavioral level only.

  19. Time windows matter in ADHD-related developing neuropsychological basic deficits: A comprehensive review and meta-regression analysis. (United States)

    Pauli-Pott, Ursula; Becker, Katja


    Normative development of neuropsychological functions that are assumed to underlie attention deficit/hyperactivity disorder (ADHD) may show transition periods, i.e., periods of heightened developmental discontinuity and reduced differential continuity. During such periods differences between ADHD cases and controls in these functions might be obscured because assessments probably not only reflect individual differences in the ADHD-related deviation but also individual differences in speed/onset of the transition. Our review focuses on executive inhibitory control (IC) and delay aversion/discounting (DA) because normative developmental processes of these characteristics are relatively well described. For complex IC performance a transition period can be assumed in preschool years, for DA around puberty. Published meta-analyses on neuropsychological IC tasks and a meta-regression analysis of 23 case-control comparisons in DA tasks comprising 1395 individuals with ADHD and 1195 controls confirmed our assumption. Effect sizes of case-control comparisons were significantly larger outside transition periods, i.e., in age-periods of relative developmental continuity. An increasingly precise identification of such time windows could contribute to the understanding of the etiological pathways of ADHD. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Mahan, Steven; Rous, Rebecca; Adlam, Anna


    Prospective memory (PM) impairments are common following acquired brain injury (ABI). PM is the ability to keep a goal in mind for future action and interventions have the potential to increase independence. This review aimed to evaluate studies examining PM rehabilitation approaches in adults and children with ABI. Relevant literature was identified using PsycARTICLES (1894 to present), PsycINFO (1880 to present), the Cochrane Library (1972 to present), MEDLINE PubMed, reference lists from relevant journal articles, and searches of key journals. Literature searches were conducted using variants of the terms brain injury, stroke, encephalitis, meningitis, and tumor, combined with variants of the terms rehabilitation and prospective memory. Of the 435 papers identified, 11 were included in the review. Findings demonstrated a variety of interventions to alleviate PM deficits, including compensatory strategies (e.g., external memory aids) that provide either content-specific or content-free cueing, and remediation strategies (e.g., meta-cognitive training programs) aimed at improving the self-monitoring of personal goals. Risk of bias for individual studies was considered and the strengths and limitations of each of the included studies and the review itself were discussed. Interventions used with adults can be effective; PM abilities can be improved by using simple reminder systems and performance can be generalized to facilitate everyday PM functioning. There is, however, a lack of research of PM interventions conducted with children with ABI, and pediatric interventions need to consider on-going cognitive maturation. (JINS, 2017, 22, 1-12).

  1. Neuropsychological deficits in mice depleted of the schizophrenia susceptibility gene CSMD1.

    Full Text Available Recent meta-analyses of schizophrenia genome-wide association studies (GWASs have identified the CUB and SUSHI multiple domains 1 (CSMD1 gene as a statistically strong risk factor. CSMD1 is a complement control-related protein suggested to inhibit the classical complement pathway, being expressed in developing neurons. However, expression of CSMD1 is largely uncharacterized and relevance for behavioral phenotypes is not previously demonstrated. Here, we assess neuropsychological behaviors of a Csmd1 knockout (KO mouse in a selection of standard behavioral tests. Deregulation of neuropsychological responses were observed in both the open field and the elevated plus maze tests, in which KO mice spent 55% and 33% less time than WT littermate mice in open areas, respectively. Altered behaviors were also observed in tail suspension and to higher acoustic stimuli, for which Csmd1 KO mice showed helplessness and moderate increase in startle amplitude, respectively. Furthermore, Csmd1 KO mice also displayed increased weight-gain and glucose tolerance, similar to a major phenotype of the metabolic syndrome that also has been associated to the human CSMD1 locus. Consistent with a role in the control of behaviors, Csmd1 was found highly expressed in the central nervous system (CNS, and with some expression in visceral fat and ovary, under tissue-specific control by a novel promoter-associated lncRNA. In summary, disruption of Csmd1 induces behaviors reminiscent of blunted emotional responses, anxiety and depression. These observations suggest an influence of the CSMD1 schizophrenia susceptibility gene on psychopathology and endophenotypes of the negative symptom spectra.

  2. Etiology And Neuropsychology Of Comorbidity Between RD And ADHD: The Case For Multiple-Deficit Models (United States)

    Willcutt, Erik G.; Betjemann, Rebecca S.; McGrath, Lauren M.; Chhabildas, Nomita A.; Olson, Richard K.; DeFries, John C.; Pennington, Bruce F.


    Introduction Attention-deficit/hyperactivity disorder (ADHD) and reading disability (RD) are complex childhood disorders that frequently co-occur, but the etiology of this comorbidity remains unknown. Method Participants were 457 twin pairs from the Colorado Learning Disabilities Research Center (CLDRC) twin study, an ongoing study of the etiology of RD, ADHD, and related disorders. Phenotypic analyses compared groups with and without RD and ADHD on composite measures of six cognitive domains. Twin analyses were then used to test the etiology of the relations between the disorders and any cognitive weaknesses. Results Phenotypic analyses supported the hypothesis that both RD and ADHD arise from multiple cognitive deficits rather than a single primary cognitive deficit. RD was associated independently with weaknesses on measures of phoneme awareness, verbal reasoning, and working memory, whereas ADHD was independently associated with a heritable weakness in inhibitory control. RD and ADHD share a common cognitive deficit in processing speed, and twin analyses indicated that this shared weakness is primarily due to common genetic influences that increase susceptibility to both disorders. Conclusions Individual differences in processing speed are influenced by genes that also increase risk for RD, ADHD, and their comorbidity. These results suggest that processing speed measures may be useful for future molecular genetic studies of the etiology of comorbidity between RD and ADHD. PMID:20828676

    Pierobon, Antonia; Giardini, Anna; Callegari, Simona; Farina, Cristiano; Torlaschi, Valeria; Bernini, Sara; Frazzitta, Giuseppe; Majani, Giuseppina


    Parkinson's Disease (PD) is characterized by a wide range of motor and non-motor symptoms. In the last years the evaluation of cognitive functioning, emotional aspects and health status of PD patients has became ever-growing important. In this article a neuropsychological and psychological assessment model, by means of tests and interviews, and a clinical approach to the narrative themes are described. Areas of clinical investigation: cognitive processing, emotional acceptance and behavioural adaptation to the disease, motivation to rehabilitation treatment, expectations regarding functional recovery, adherence, social and family perceived support, mood, awareness of possible cognitive deficits. Tests assessment (based on specific cognitive deficits related to PD): MMSE, FAB, TMTA-B, Phonological verbal fluency test, Stroop test, Geriatric Depression Scale (GDS) or Beck Depression Inventory- BDI-II and Parkinson's Disease Questionnaire-8 (PDQ-8). The psychological approach, which is part of an interdisciplinary rehabilitative intervention, is based on Cognitive Behavioural Therapy and it is focused on disease management even in the absence, sometimes, of a significant general emotional status modification and it is aimed at improving patient's adaptability, self-management and empowerment. In order to describe the model, the clinical and test data of two PD patients are illustrated. The added value of this psychological approach lies in the clinical data integration of the test evaluation, the narrative aspects and the information mediated by the inter-professional team. This model allows a deeper and more personalized identification of the patient's subjective adjustment process according to his/her personal needs and resources.

  4. Sensory Gating Deficits in First-Episode Psychosis: Evidence From Neurophysiology, Psychophysiology, and Neuropsychology. (United States)

    Morales-Muñoz, Isabel; Jurado-Barba, Rosa; Fernández-Guinea, Sara; Rodríguez-Jiménez, Roberto; Jiménez-Arriero, Miguel Ángel; Criado, José R; Rubio, Gabriel


    Sensory gating deficits are commonly found in patients with schizophrenia. However, there is still scarce research on this issue. Thirty-eight patients with first-episode psychosis (FEP) were compared to thirty-eight controls. A condition-test paradigm of event-related potentials (ERP), prepulse inhibition (PPI), and some specific tasks of the MATRICS Consensus Cognitive Battery (MCCB) were used (i.e., TMT, BACS-SC, and Fluency for processing speed and CPT-IP for attention and vigilance). The ERP components measured were P50, N1, and P2. The PPI intervals examined were 30, 60, and 120 msec. Regarding the MCCB, processing speed and attention/vigilance cognitive domains were selected. FEP patients showed significant deficits in N1 and P2 components, at 30 and 60 PPI levels and in all the MCCB subtests selected. We obtained significant relationships in N1 with PPI-60, and with one MCCB subtest for processing speed. In addition, this same subtest showed significant association with P2. Therefore, sensory gating functioning is widely impaired since the very early stages of schizophrenia.

    Levent, Neslihan; Tümkaya, Selim; Ateşçi, Figen; Tüysüzoğlu, Halide; Varma, Gülfizar; Oğuzhanoğlu, Nalan


    The present study aimed to compare cognitive signs of bipolar disorder patients with that of adult attention-deficit/hyperactivity disorder (ADHD) patients. The study comprised 66 bipolar disorder patients, 63 ADHD patients, and 58 healthy controls.Structured Clinical Interview for DSM-IV Axis-I Disorders (SCID-I), Wender Utah Rating Scale, and Adult Attention-Deficit/Hyperactivity Rating Scale were performed in all subjects, whereas bipolar disorder patients underwent additional Hamilton Depression Rating Scale and Young Mania Rating Scale. Subsequently, all participants underwent cognitive assessment including Digit Ordering Test, Verbal Memory Process Test, Wisconsin Card Sorting Test and Stroop Test. Bipolar disorder, ADHD and control groups did not differ significantly from each other with regard to age, sex and duration of education. Bipolar patients displayed poorer performance in Digit Span Test, Verbal Memory Process Test, Wisconsin Card Sorting Test and Stroop Test as compared to the control group. ADHD patients were worse than the control subjects in Stroop Test (subtest of difference in times). Bipolar disorder patients were poorer than ADHD patients in cognitive tests except for Stroop Test. In general, bipolar disorder patients have much more severe cognitive impairment than ADHD patients in terms of verbal memory and executive functions. The results supports the idea of bipolar disorder and ADHD are different, at least in terms of cognitive performance.

  6. Trends on the application of serious games to neuropsychological evaluation: A scoping review. (United States)

    Valladares-Rodríguez, Sonia; Pérez-Rodríguez, Roberto; Anido-Rifón, Luis; Fernández-Iglesias, Manuel


    The dramatic technological advances witnessed in recent years have resulted in a great opportunity for changing the way neuropsychological evaluations may be performed in clinical practice. Particularly, serious games have been posed as the cornerstone of this still incipient paradigm-shift, as they have characteristics that make them especially advantageous in trying to overcome limitations associated with traditional pen-and-paper based neuropsychological tests: they can be easily administered and they can feature complex environments for the evaluation of neuropsychological constructs that are difficult to evaluate through traditional tests. The objective of this study was to conduct a scoping literature review in order to map rapidly the key concepts underpinning this research area during the last 25years on the use of serious games for neuropsychological evaluation. MEDLINE, PsycINFO, Scopus and IEEE Xplore databases were systematically searched. The main eligibility criteria were to select studies published in a peer-reviewed journal; written in English; published in the last 25years; focused on the human population, and classified in the neuropsychological field. Moreover, to avoid risk of bias, studies were selected by consensus of experts, focusing primarily in psychometric properties. Therefore, selected studies were analyzed in accordance with a set of dimensions of analysis commonly used for evaluating neuropsychological tests. After applying the selected search strategy, 57 studies -including 54 serious games- met our selection criteria. The selected studies deal with visuospatial capabilities, memory, attention, executive functions, and complex neuropsychological constructs such as Mild Cognitive Impairment (MCI). Results show that the implementation of serious games for neuropsychological evaluation is tackled in several different ways in the selected studies, and that studies have so far been mainly exploratory, just aiming at testing the

  7. Transcallosal approach to tumors of the third ventricle. Surgical results and neuropsychological evaluation. (United States)

    Villani, R; Papagno, C; Tomei, G; Grimoldi, N; Spagnoli, D; Bello, L


    A series of 34 patients with tumours of the third ventricle were operated on by a transcallosal route. Basal extrinsic lesions compressing or invading the ventricle as well as tumours located in the pineal area were excluded from this review. Tumours were approached by a transforaminal entry in 16 cases (47%), by an interforniceal route in 11 (32%), by a subchoroidal entry in 4 (14%) and by a combined transforaminal and subchoroidal entry in 3 (9%). Four out of 34 patients were submitted to a second operation, through the same approach corridor: 2 for an incomplete removal of an intrinsic tumour and 2 for a late regrowth. Postoperative mortality rate accounted for 5.8% (2 patients). Major post operative complications were hemiparesis (4 patients) and diabetes insipidus (4 patients), that were transient in 3. Akinetic mutism like status was observed in only 1 patient. Postoperative psychic disturbances were noticed in 5 cases. Nine out of 21 patients (62%) with preoperative hydrocephalus required a permanent CSF shunt. Histology revealed that 21 tumours (62%) were intraaxial (4 pilocitic astrocytoma, 10 low grade glioma, 1 giant cell astrocytoma, 1 subependymoma, 4 ependymoma/ependymoblastoma, 1 neurocitoma) and 13 (38%) were extraaxial (8 colloid cyst, 2 craniopharingioma, 1 ectopic pituitary adenoma, 1 lymphocytic hypophysitis and 1 metastasis). Total excision of third ventricle tumours was achieved in all patients with extraaxial tumours and in 62% and 71% of intraaxial tumours with the first and second surgical procedure respectively. Ten out of 34 patients of this series were submitted to a complete neuropsychological evaluation at an interval of 2-9 years after surgery. Memory tests were pathological in 2. Disconnection signs were constantly absent. Control function were preserved. Transcallosal approach remains the best microsurgical method of third ventricle tumours treatment. This route provides the capability for a superior visualization of the entire

  8. Cognitive impairment in depressive disorders. Neuropsychological evaluation of memory and behavioural disturbances. (United States)

    Emilien, G; Penasse, C; Waltregny, A


    The purpose of this article is to discuss the contribution that clinical neuropsychology and neuropsychological assessment can conter to neuropsychiatry, particularly in the evaluation of cognitive disturbances and pharmacological treatment of depression. Six patients (4 females, 2 males; age: 16-54 years old) suffering from depressive disorders underwent a clinical neuropsychological examination. Depending on the memory scores obtained on the Rey-Osterrieth complex figure test, the patients were classified as having mild or no memory impairment (memory impairment (20-40% decrease) or severe memory alteration (> 60% deterioration). Evaluation of memory scores of two other memory tests (Wechsler memory scale and Rey visual design learning test) were also considered. Patients who were classified as having severe memory impairment were consistently reported as seriously impaired on all memory tests. The severity of cognitive dysfunction is in accordance with the serious ness of the neuropsychiatric disturbances of the patients as revealed by personality testing (MMPI, IDS and Eysenck questionnaires) or by personal details as assessed during the interview. This paper discusses the importance of the utility of a comprehensive neuropsychological evaluation of depressed patients and seriously considers the possibility of the use of this approach for pharmacological treatment evaluation.

  9. Effects of handcuffs on neuropsychological testing: Implications for criminal forensic evaluations. (United States)

    Biddle, Christine M; Fazio, Rachel L; Dyshniku, Fiona; Denney, Robert L


    Neuropsychological evaluations are increasingly performed in forensic contexts, including in criminal settings where security sometimes cannot be compromised to facilitate evaluation according to standardized procedures. Interpretation of nonstandardized assessment results poses significant challenges for the neuropsychologist. Research is limited in regard to the validation of neuropsychological test accommodation and modification practices that deviate from standard test administration; there is no published research regarding the effects of hand restraints upon neuropsychological evaluation results. This study provides preliminary results regarding the impact of restraints on motor functioning and common neuropsychological tests with a motor component. When restrained, performance on nearly all tests utilized was significantly impacted, including Trail Making Test A/B, a coding test, and several tests of motor functioning. Significant performance decline was observed in both raw scores and normative scores. Regression models are also provided in order to help forensic neuropsychologists adjust for the effect of hand restraints on raw scores of these tests, as the hand restraints also resulted in significant differences in normative scores; in the most striking case there was nearly a full standard deviation of discrepancy.

    Full Text Available Objective: To investigate cognitive deficits in patients with primary Sjögren’s syndrome (PSS. Method: Eighteen patients with PSS, aged between 25 and 61 years, were subjected to a short neuropsychological battery and compared with 18 patients with multiple sclerosis and 18 healthy controls. Results: The analysis of variance (ANOVA revealed that the clinical groups had significantly worse performance than the control group on the Rey Auditory Verbal Learning Test 3; (F 2,53 =3.500, p=0.038 and 7 (F 2,53 =5.068, p=0.010. The clinical groups had elevated levels of depression on the Beck Depression Inventory (BDI; (p=0.003. The analysis of the data from the Trail Making Test B-A revealed a significant difference between the clinical and control groups (p=0.023. The analysis of covariance with BDI score as a covariate, did not change the outcome. Conclusion: Our study revealed cognitive deficits in patients with PSS detectable by a short neuropsychological battery.

  11. The foundations of next generation attention-deficit/hyperactivity disorder neuropsychology: building on progress during the last 30 years. (United States)

    Sonuga-Barke, Edmund J S; Coghill, David


    In this short overview we have illustrated 30 years of progress in the field of ADHD neuropsychology through a selective presentation of studies published in the JCPP. Clearly this is not an exhaustive list of papers (we had to leave many excellent studies out) and obviously many studies published in other journals have had an equally significant impact on the field. Nevertheless, it is clear that the JCPP has contributed in important ways to providing the empirical and intellectual foundations of the next generation of ADHD neuropsychological models in terms of insight regarding context dependence, complexity and heterogeneity, and diagnostic specificity and sensitivity. Furthermore, articles have highlighted the importance of a developmental perspective on neuropsychological deficits in ADHD as well as the possibility that they could be targeted with new and novel treatments. Our hope is that we will continue to witness similar growth in understanding over the next 30 years, and that the JCPP will continue to be at the forefront of this progress. © 2014 Association for Child and Adolescent Mental Health.

  12. Neuropsychological dysfunction in patients with end-stage pulmonary disease: lung transplant evaluation (United States)

    Crews, W. David; Jefferson, Angela L.; Broshek, Donna K.; Rhodes, Robert D.; Williamson, John; Brazil, Amy M.; Barth, Jeffrey T.; Robbins, Mark K.


    There has been a relative absence of studies that have examined the neuropsychological profiles of potential lung transplant candidates. Neuropsychological data are presented for 134 patients with end-stage pulmonary disease who were being evaluated as potential candidates for lung transplantation. Neuropsychological test results indicated that a significantly greater proportion of the patients exhibited impaired performances on a number of Selective Reminding Test (SRT) tasks as compared to the expected population frequency distributions for these measures. The highest frequencies of impairment were observed on the SRT’s Immediate Free Recall (46.43%), Long-term Retrieval (41.67%), and Consistent Long-term Retrieval (51.19%) variables. On the Minnesota Multiphasic Personality Inventory-2 (MMPI-2)/Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A), patients’ mean clinical profile revealed elevations on Scales 1 (Hypochondriasis) and 3 (Conversion Hysteria). This profile indicated that they were experiencing an array of symptomatology ranging from somatic complaints to lethargy and fatigue, and that they may have been functioning at a reduced level of efficiency. Findings are discussed in light of patients’ end-stage pulmonary disease and factors possibly contributing to their neuropsychological test performances. Implications for clinical practice and future research are also provided. PMID:14591451

  13. CE Neuropsychological and neurobehavioral outcome following childhood arterial ischemic stroke: Attention deficits, emotional dysregulation, and executive dysfunction (United States)

    Liégeois, Frédérique; Eve, Megan; Ganesan, Vijeya; King, John; Murphy, Tara


    Objectives To investigate neuropsychological and neurobehavioral outcome in children with arterial ischemic stroke (AIS). Background Childhood stroke can have consequences on motor, cognitive, and behavioral development. We present a cross-sectional study of neuropsychological and neurobehavioral outcome at least one year poststroke in a uniquely homogeneous sample of children who had experienced AIS. Method Forty-nine children with AIS aged 6 to 18 years were recruited from a specialist clinic. Neuropsychological measures of intelligence, reading comprehension, attention, and executive function were administered. A triangulation of data collection included questionnaires completed by the children, their parents, and teachers, rating behavior, executive functions, and emotions. Key Findings Focal neuropsychological vulnerabilities in attention (response inhibition and dual attention) and executive function were found, beyond general intellectual functioning, irrespective of hemispheric side of stroke. Difficulties with emotional and behavioral regulation were also found. Consistent with an “early plasticity” hypothesis, earlier age of stroke was associated with better performance on measures of executive function. Conclusions A significant proportion of children poststroke are at long-term risk of difficulties with emotional regulation, executive function, and attention. Data also suggest that executive functions are represented in widespread networks in the developing brain and are vulnerable to unilateral injury. PMID:24028185

    R. Ávila


    Full Text Available Patients with Alzheimer's disease (AD gradually lose their cognitive competence, particularly memory, and the ability to perform daily life tasks. Neuropsychological rehabilitation is used to improve cognitive functions by facilitating memory performance through the use of external aids and internal strategies. The effect of neuropsychological rehabilitation through memory training - motor movements, verbal association, and categorization - and activities of daily living (ADL training was tested in a sample of 5 elderly out-patients (mean age: 77.4 ± 2.88 years, with mild AD (Mini-Mental State Examination score: 22.20 ± 2.17 and their caregivers. All patients had been taking rivastigmine (6-12 mg/day for at least 3 months before being assigned to the rehabilitation sessions, and they continued to take the medication during the whole program. Just before and after the 14-week neuropsychological rehabilitation program all patients were assessed by interviewers that did not participate in the cognitive training, using the Mini-Mental State Examination, Montgomery-Alsberg Depression Rating Scale, Hamilton Anxiety Scale, Interview to Determine Deterioration in Functioning in Dementia, Functional Test, Memory Questionnaire of Daily Living for patient and caregiver, Quality of Life Questionnaire for patient and caregiver, and a neuropsychological battery. The results showed a statistically significant improvement in ADL measured by Functional Test (P = 0.04, and only a small improvement in memory and psychiatric symptoms. Our results support the view that weekly stimulation of memory and training of ADL is believed to be of great value in AD treatment, not only delaying the progress of the disease, but also improving some cognitive functions and ADL, even though AD is a progressively degenerative disease.

  17. Neuropsychological profiles correlated with clinical and behavioral impairments in a sample of Brazilian children with Attention Deficit Hyperactivity Disorder (ADHD

    Directory of Open Access Journals (Sweden)

    Sueli eRizzutti


    Full Text Available ADHD is a complex neurodevelopmental disorder that implies several-step process and there is no single test to diagnose both ADHD and associated comorbidities such as oppositional defiant disorder, anxiety disorder, depression and certain types of learning disabilities. The purpose of the present study was to examine correlations between behavioral and clinical symptoms by administering an extensive neuropsychological battery to a sample of children and adolescents from a developing country. The sample was divided into three groups: non-ADHD; ADHD-non-comorbid; and ADHD+comorbidity. A full neuropsychological battery and clinical assessment found that 105 children met DSM-5 criteria, of whom 46.6% had the predominantly inattentive presentation, 37.3% had combined presentation and 16% were predominantly hyperactive/impulsive presentation. The internal correlation between neuropsychological tests did not reach statistical significance in the comparison between ADHD and non-ADHD cases (p<0.17. Clinical ADHD cases, including both +comorbidity and non-comorbid groups, performed substantially worse on CPT, working memory. Comparing ADHD-non-comorbid and ADHD+comorbidity groups, the latter did significantly worse on inhibitory control, time processing and the level of perseveration response on CPT indexes, as well as on working memory performance and CBCL tests particularly the CBCL-DESR (deficient emotional self-regulation test in the ADHD+comorbidity group. Children diagnosed as oppositional-defiant (ODD or with conduct disorder (CD showed close correlations between clinical CBCL profiles and externalized symptoms. Our findings suggest that ADHD+comorbidity and ADHD non-comorbid cases may be differentiated by a number of neuropsychological measures, such as processing speed, inhibitory control and working memory, that may reflect different levels of involvement of the hot and cool executive domains, which are more impaired in cases of severe

  18. An Intervention to Decrease the Occurrence of Invalid Data on Neuropsychological Evaluation. (United States)

    Horner, Michael David; Turner, Travis H; VanKirk, Kathryn K; Denning, John H


    This study tested whether patients who were given a handout based on deterrence theory, immediately prior to evaluation, would provide invalid data less frequently than patients who were simply given an informational handout. All outpatients seen for clinical evaluation in a VA Neuropsychology Clinic were randomly given one of the two handouts immediately prior to evaluation. The "Intervention" handout emphasized the importance of trying one's hardest, explicitly listed consequences of valid and invalid responding and asked patients to sign and initial it. The "Control" handout provided general information about neuropsychological evaluation. Examiners were blinded to condition. Patients were excluded from analyses if they were diagnosed with major neurocognitive disorder or could not read the handout. Medical Symptom Validity Test (MSVT) was used to determine performance validity. Groups did not differ on age, education, or litigation status. For the entire sample (N = 251), there was no effect of handout on passing versus failing MSVT. However, among patients who were seeking disability benefits at the time of evaluation (n = 70), the Intervention handout was associated with lower frequency of failing MSVT than the Control handout. This brief, theory-based, cost-free intervention was associated with lower frequency of invalid data among patients seeking disability benefits at the time of clinical evaluation. We suggest methodological modifications that might produce a more potent intervention that could be effective with additional subsets of patients.

  20. A signal detection-item response theory model for evaluating neuropsychological measures. (United States)

    Thomas, Michael L; Brown, Gregory G; Gur, Ruben C; Moore, Tyler M; Patt, Virginie M; Risbrough, Victoria B; Baker, Dewleen G


    Models from signal detection theory are commonly used to score neuropsychological test data, especially tests of recognition memory. Here we show that certain item response theory models can be formulated as signal detection theory models, thus linking two complementary but distinct methodologies. We then use the approach to evaluate the validity (construct representation) of commonly used research measures, demonstrate the impact of conditional error on neuropsychological outcomes, and evaluate measurement bias. Signal detection-item response theory (SD-IRT) models were fitted to recognition memory data for words, faces, and objects. The sample consisted of U.S. Infantry Marines and Navy Corpsmen participating in the Marine Resiliency Study. Data comprised item responses to the Penn Face Memory Test (PFMT; N = 1,338), Penn Word Memory Test (PWMT; N = 1,331), and Visual Object Learning Test (VOLT; N = 1,249), and self-report of past head injury with loss of consciousness. SD-IRT models adequately fitted recognition memory item data across all modalities. Error varied systematically with ability estimates, and distributions of residuals from the regression of memory discrimination onto self-report of past head injury were positively skewed towards regions of larger measurement error. Analyses of differential item functioning revealed little evidence of systematic bias by level of education. SD-IRT models benefit from the measurement rigor of item response theory-which permits the modeling of item difficulty and examinee ability-and from signal detection theory-which provides an interpretive framework encompassing the experimentally validated constructs of memory discrimination and response bias. We used this approach to validate the construct representation of commonly used research measures and to demonstrate how nonoptimized item parameters can lead to erroneous conclusions when interpreting neuropsychological test data. Future work might include the

  2. Evaluating the subject-performed task effect in healthy older adults: relationship with neuropsychological tests

    Directory of Open Access Journals (Sweden)

    Ana Rita Silva


    Full Text Available Background: An enhancement in recall of simple instructions is found when actions are performed in comparison to when they are verbally presented – the subject-performed task (SPT effect. This enhancement has also been found with older adults. However, the reason why older adults, known to present a deficit in episodic memory, have a better performance for this type of information remains unclear. In this article, we explored this effect by comparing the performance on the SPT task with the performance on other tasks, in order to understand the underlying mechanisms that may explain this effect. Objective: We hypothesized that both young and older adult groups should show higher recall in SPT compared with the verbal learning condition, and that the differences between age groups should be lower in the SPT condition. We aimed to explore the correlations between these tasks and known neuropsychological tests, and we also measured source memory for the encoding condition. Design: A mixed design was used with 30 healthy older adults, comparing their performance with 30 healthy younger adults. Each participant was asked to perform 16 simple instructions (SPT condition and to only read the other 16 instructions (Verbal condition – VT. The test phase included a free recall task. Participants were also tested with a set of neuropsychological measures (speed of processing, working memory and verbal episodic memory. Results: The SPT effect was found for both age groups; but even for SPT materials, group differences in recall persisted. Source memory was found to be preserved for the two groups. Simple correlations suggested differences in correlates of SPT performance between the two groups. However, when controlling for age, the SPT and VT tasks correlate with each other, and a measure of episodic memory correlated moderately with both SPT and VT performance. Conclusions: A strong effect of SPT was observed for all but one, which still displayed the

  3. A critical evaluation of the validity of episodic future thinking: A clinical neuropsychology perspective. (United States)

    Ward, Amanda M


    Episodic future thinking is defined as the ability to mentally simulate a future event. Although episodic future thinking has been studied extensively in neuroscience, this construct has not been explored in depth from the perspective of clinical neuropsychology. The aim of this critical narrative review is to assess the validity and clinical implications of episodic future thinking. A systematic review of episodic future thinking literature was conducted. PubMed and PsycInfo were searched through July 2015 for review and empirical articles with the following search terms: "episodic future thinking," "future mental simulation," "imagining the future," "imagining new experiences," "future mental time travel," "future autobiographical experience," and "prospection." The review discusses evidence that episodic future thinking is important for adaptive functioning, which has implications for neurological populations. To determine the validity of episodic future thinking, the construct is evaluated with respect to related constructs, such as imagination, episodic memory, autobiographical memory, prospective memory, narrative construction, and working memory. Although it has been minimally investigated, there is evidence of convergent and discriminant validity for episodic future thinking. Research has not addressed the incremental validity of episodic future thinking. Practical considerations of episodic future thinking tasks and related constructs in a clinical neuropsychological setting are considered. The utility of episodic future thinking is currently unknown due to the lack of research investigating the validity of episodic future thinking. Future work is discussed, which could determine whether episodic future thinking is an important missing piece in standard clinical neuropsychological assessment.

    Full Text Available Abstract Background: Individuals with sickle cell anemia may suffer symptomatic or silent cerebral infarcts leading to neurocognitive complications. This study investigated the cognitive and intellectual performance of children and adolescents with sickle cell anemia. Methods: The socioeconomic status, clinical aspects and behavioral profile of 15 young individuals with sickle cell anemia were evaluated. The Wechsler Intelligence Scale for Children, the Developmental Neuropsychological Assessment Test, and the Child Behavior Checklist were applied. Results: Participants with a history of stroke had lower intelligence quotient (IQ scores. Alterations were found in attention and executive functioning, language, verbal and visual memory, visuospatial processing and sensorimotor skills. These alterations were found both in the children and adolescents who had had a cerebral infarction and in those who apparently had not. In the majority of cases, there were learning difficulties, a history of repeating school years and a need for specialist educational support. The most common additional diagnoses in accordance with the Diagnostic and Statistical Manual of Mental Disorders IV were depressive disorder, anxiety disorder and somatic disorder, as well as conditions associated with physical and psychosocial repercussions of sickle cell anemia. Conclusion: As sickle cell anemia is considered a progressive cerebral vasculopathy, it is a potential risk factor for neurocognitive and psychosocial development. Therefore, periodic neuropsychological and behavioral evaluations of children and adolescents with sickle cell anemia may represent a useful measure to reduce long-term biopsychosocial repercussions.

  6. Schizophrenia, culture and neuropsychology: sensory deficits, language impairments and social functioning in Chinese-speaking schizophrenia patients. (United States)

    Yang, L; Chen, S; Chen, C-M; Khan, F; Forchelli, G; Javitt, D C


    While 20% of schizophrenia patients worldwide speak tonal languages (e.g. Mandarin), studies are limited to Western-language patients. Western-language patients show tonal deficits that are related to impaired emotional processing of speech. However, language processing is minimally affected. In contrast, in Mandarin, syllables are voiced in one of four tones, with word meaning varying accordingly. We hypothesized that Mandarin-speaking schizophrenia patients would show impairments in underlying basic auditory processing that, unlike in Western groups, would relate to deficits in word recognition and social outcomes. Altogether, 22 Mandarin-speaking schizophrenia patients and 44 matched healthy participants were recruited from New York City. The auditory tasks were: (1) tone matching; (2) distorted tunes; (3) Chinese word discrimination; (4) Chinese word identification. Social outcomes were measured by marital status, employment and most recent employment status. Patients showed deficits in tone-matching, distorted tunes, word discrimination and word identification versus controls (all psocial outcomes, tonally impaired patients had 'lower-status' jobs overall when compared with tonally intact patients (pculturally, their consequences may be language- and culture-dependent.

Dept. of Medical Physics (United Kingdom)); Crawford, J.R. (Aberdeen University Medical School (United Kingdom). Department of Psychology (United Kingdom)); Besson, J.A.O. (Aberdeen University Medical School (United Kingdom). Department of Mental Health (United Kingdom))


    By means of psychometric testing, we have determined the frequency of latent hepatic encephalopathy in a group of 19 cirrhotics with no clinical evidence of encephalopathy. Magnetic resonance imaging (MRI) of the brain was performed in order to determine whether morphological cerebral abnormalities were associated with latent encephalopathy. Nineteen age and educationally matched patient with normal liver function acted as controls. Significant differences (P < 0.05) between cirrhotics and controls were found in tests of short-term visual memory and speed of reaction to light (cirrhotics 326 ( 132 ms vs. controls 225 ) 36 ms), sound (cirrhotics 361 ( 152 ms vs. controls 236 ) 52 ms) and choice (cirrhotics 651 ( 190 ms vs. controls 406 ) 101 ms) stimuli (all values mean S.D.). Reitan trail test performance, however, was similar in both groups. ( Trail A: cirrhotics 43 ( 19 s vs. controls 35 ) 13 s; Trail B: cirrhotics 105 ( 66 s vs. controls 93 ) 36 s.) In patients with cirrhosis, MRI revealed statistically significant increases in the maximum fissure width of right frontal sulci, light and left parietal sulci, inter-hemispheric fissure width and in bicaudafe index. These changes, indicating cerebral atrophy, were largely confined to alcoholics. There was poor correlation between measurements of cerebral morphology and neuropsychological performance, only 10% of associations achieving statistical significance.

  8. Neuropsychological function in Tourette syndrome. (United States)

    Como, P G


    The accumulated body of scientific evidence regarding intellectual function, presence of learning disorders, and specific neuropsychological deficits in TS suggests that difficulties in these areas are present in a significant percentage of patients with TS. Despite the numerous methodological shortcomings of past neuropsychological studies of TS, relatively robust and consistent findings have emerged. The literature to date has suggested that intellectual ability is normally distributed in TS. Whether or not individuals with TS have significant discrepancies between their verbal and nonverbal abilities remains unclear. The prevalence of learning disabilities in TS has been reported to be similar to the base rates reported for the general population, although there is evidence to suggest that the prevalence of LDs in children with TS may actually be lower and specific for difficulties in math and written language. Specific cognitive deficits in TS consist of visuomotor integration problems, impaired fine motor skill, and executive dysfunction. The presence of comorbid conditions, notably ADHD and OCD, appears to significantly increase the likelihood that an individual with TS will also have learning problems or some demonstrable cognitive impairment. The presence of a learning disability, specific academic deficiency, or cognitive deficit may pose a greater obstacle for persons with TS than the tic disorder itself. This is particularly salient for children with TS, who may be at a higher risk for poor school performance and academic failure. The psychosocial impact of these problems is also far-reaching. Given the recent emphasis on the early detection of academic and learning problems, it would seem prudent that children with TS who are suspected of having neuropsychological difficulties be evaluated as soon as possible. There are numerous educational interventions and accommodations available to children with LDs and/or specific academic weaknesses that can work

  9. Neuropsychology in India. (United States)

    Kumar, J Keshav; Sadasivan, Akila


    This is an invited paper for a special issue with the objective to provide information on neuropsychology in India. Information was gathered from a literature search and personal communication with professionals working in the field of neuropsychology. Neuropsychology as a specialization started in India approximately 40 years ago. The early years witnessed the use of Western tools for assessing patients with organic brain damage. Subsequent years saw the development of indigenous tools for use with the vast majority of the Indian population and also a few Western tests adapted to suit the needs of the unique Indian clientele. The starting of the Neuropsychology unit at the National Institute of Mental Health and Neurosciences (NIMHANS) in Bangalore in 1975 resulted in changing of the course of training and practice of Neuropsychology. The field of assessments has witnessed indigenous tests being developed, while rehabilitation programs have brought about a decline in cognitive deficits in several clinical conditions. Currently, work within the field of neuropsychology has focused on child, geriatric, acquired brain injury, and forensic populations with a development of unique rehabilitations to suit needs of several clinical conditions. However, there are very few neuropsychologists in the country, and only one nodal training center, which limits the availability of training to the large population of the country. Despite the shortcomings, the field of neuropsychology has received much attention in the recent years with the number of referrals and professionals increasing.

  10. Genotype and neuropsychological response inhibition as resilience promoters for attention-deficit/hyperactivity disorder, oppositional defiant disorder, and conduct disorder under conditions of psychosocial adversity. (United States)

    Nigg, Joel; Nikolas, Molly; Friderici, Karen; Park, Leeyoung; Zucker, Robert A


    Whereas child personality, IQ, and family factors have been identified as enabling a resilient response to psychosocial adversity, more direct biological resilience factors have been less well delineated. This is particularly so for child attention-deficit/hyperactivity disorder (ADHD), which has received less attention from a resilience perspective than have associated externalizing disorders. Children from two independent samples were classified as resilient if they avoided developing ADHD, oppositional defiant disorder (ODD), or conduct disorder (CD) in the face of family adversity. Two protective factors were examined for their potential relevance to prefrontal brain development: neuropsychological response inhibition, as assessed by the Stop task, and a composite catecholamine genotype risk score. Resilient children were characterized in both samples by more effective response inhibition, although the effect in the second sample was very small. Genotype was measured in Sample 1, and a composite high risk genotype index was developed by summing presence of risk across markers on three genes expressed in prefrontal cortex: dopamine transporter, dopamine D4 receptor, and noradrenergic alpha-2 receptor. Genotype was a reliable resilience indicator against development of ADHD and CD, but not ODD, in the face of psychosocial adversity. Results illustrate potential neurobiological protective factors related to development of prefrontal cortex that may enable children to avoid developing ADHD and CD in the presence of psychosocial adversity.

  11. The parametric, psychological, neuropsychological, and neuroanatomical properties of self and world evaluation.

    Directory of Open Access Journals (Sweden)

    Alan N Simmons

    Full Text Available As an individual moves from adolescence to adulthood, they need to form a new sense of self as their environment changes from a limited to a more expansive structure. During this critical stage in development the last dramatic steps of neural development occur and numerous psychiatric conditions begin to manifest. Currently, there is no measure that aids in the quantification of how the individual is adapting to, and conceptualizing their role in, these new structures. To fill this gap we created the Self and World Evaluation Expressions Test(SWEET.Sixty-five young adults (20.6 years-old, 36 with a history of drug use, completed the SWEET. A factor analysis was performed on the SWEET and the resultant factors were correlated with psychological, neuropsychological, and neuroanatomical battery that included both T1-wieghted and diffusion tensor magnetic resonance imaging scans.WE DERIVED FOUR FACTORS: Self, Social-Emotional, Financial-Intellectual, and Spirituality. While showing limited relationships to psychological and neuropsychological measures, both white matter integrity and gray matter density showed significant relationships with SWEET factors.These findings suggest that while individual responses may not be indicative of psychological or cognitive processes they may relate to changes in brain structure. Several of these structures, such as the negative correlation of the affective impact of world with the dorsal anterior corpus callosum white matter integrity have been observed in psychiatric conditions (e.g., obsessive-compulsive disorder. Further longitudinal research using the SWEET may help understand the impact of dramatic shifts in self/world conceptualization and potentially link these shifts to underlying changes in brain structure.

    UCL's former provost, Sir Derek Roberts, has been drafted in for a year to run the college. UCL is expected to have a 6 million pounds deficit this year and up to a 10 million pounds deficit next year. Sir Christopher Llewellyn-Smith took over at UCL nearly 4 years ago and decided then that the finanical situation was serious enough to warrant a reduction in the vast expansion policy undertaken by his predecessor (1 page).

  14. Neuropsychology of acute stroke. (United States)

    Sinanović, Osman


    Neuropsychology includes both the psychiatric manifestations of neurological illness (primary brain-based disorders) and neurobiology of "idiopathic" psychiatric disorders. Neurological primary brain disorders provoke broad spectrum of brain pathophysiology that cause deficit sin human behaviour, and the magnitude of neurobehavioral-related problems is a world wide health concern. Speech disorders of aphasic type, unilateral neglect, anosognosia (deficit disorders), delirium and mood disorders (productive disorders) in urgent neurology, first of all in acute phase of stroke are more frequent disorders then it verified in routine exam, not only in the developed and large neurological departments. Aphasia is common consequence of left hemispheric lesion and most common neuropsychological consequence of stroke, with prevalence of one third of all stroke patients in acute phase although exist reports on greater frequency. Unilateral neglect is a disorder that mostly effects the patient after the lesion of the right hemisphere, mostly caused by a cerebrovascular insult (infarct or haemorrhage affecting a large area - up to two thirds of the right hemisphere), and in general the left-side neglect is the most widespread neuropsychological deficit after the lesion of the right cerebral hemisphere. Reports on the incidence of visual neglect vary and they range from 13 to 85%. Anosognosia is on the second place as neuropsychological syndrome of stroke in right hemisphere, characterized by the denial of the motor, visual or cognitive deficit. This syndrome, defined as denial of hemiparesis or hemianopsia, is a common disorder verified in 17-28% of all patents with acute brain stoke. There are different reports on frequency of delirium in acute stroke, from 24 to 48%, and it is more frequent in hemorrhagic then ischemic stoke. Post stroke depression (PSD) is one of the more frequent consequences on the stroke, and the prevalence of PSD has ranged from 5 to 63% of patients in

  15. Comparison of Montreal Cognitive Assessment and Mini-Mental State Examination in Evaluating Cognitive Domain Deficit Following Aneurysmal Subarachnoid Haemorrhage (United States)

    Wong, George Kwok Chu; Lam, Sandy Wai; Wong, Adrian; Ngai, Karine; Poon, Wai Sang; Mok, Vincent


    Objective Cognitive deficits are common after aneurysmal subarachnoid haemorrhage (aSAH), and clinical evaluation is important for their management. Our hypothesis was that the Montreal Cognitive Assessment (MoCa) is superior to the Mini-Mental State Examination (MMSE) in screening for cognitive domain deficit in aSAH patients. Methods We carried out a prospective observational and diagnostic accuracy study on Hong Kong aSAH patients aged 21 to 75 years who had been admitted within 96 hours of ictus. The domain-specific neuropsychological assessment battery, the MoCA and MMSE were administered 2–4 weeks and 1 year after ictus. A cognitive domain deficit was defined as a cognitive domain z score ictus, the MoCA produced higher area under the curve scores for cognitive impairment than the MMSE (MoCA, 0.92; 95% CI, 0.83 to 0.97 versus MMSE, 0.77; 95% CI, 0.66 to 0.83, p = 0.009). Interpretation Cognitive domain deficits and cognitive impairment in patients with aSAH can be screened with the MoCA in both the subacute and chronic phases. PMID:23573223

  18. [Neuropsychological performance in neurofibromatosis type 1]. (United States)

    Hernández Del Castillo, Lilia; Martínez Bermejo, Antonio; Portellano Pérez, José Antonio; Tirado Requero, Pilar; Garriz Luis, Alexandra; Velázquez Fragua, Ramón


    Neurofibromatosis type 1 (NF1) is a genetic disorder with various clinical manifestations that affect the peripheral and central nervous system, as well as the skin, bones and endocrine and vascular system. There is still insufficient knowledge of neuropsychological effects of NF1 on children, and there is some controversy about the cognitive deficits that defines the cognitive profile of patients affected by this disorder. In this study an analysis is made of the neuropsychological performance of a group of patients affected by NF1, compared with a control group of healthy children. A comparison was made between the neuropsychological performance of a group of 23 boys and girls with a mean age of 8.7 years (+/-1.39) and diagnosed with NF1, and a control group consisting of 21 healthy children, with mean age of 8.9 years (+/- 1.41) and with similar socio-demographic characteristics. The Wechsler Intelligence Scale for Children (WISC) was applied to evaluate the subjects of both groups. The group of patients affected with NF1 showed a lower performance in every primary index of WISC IV: Verbal Comprehension Index, Fluid Reasoning Index, Working Memory Index, Processing Speed Index, and full Scale IQ. Only in two subscales were no statistically significant differences observed: similarities and coding. The results show subtle and generalised neuropsychological alterations in the sample of children affected with NF1, which affect most of cognitive domains that have been evaluated. Proper specific and early neuropsychological treatment should be provided in order to prevent the high risk for these children of presenting learning difficulties and school failure.

  20. Controlled evaluation of a neurofeedback training of slow cortical potentials in children with Attention Deficit/Hyperactivity Disorder (ADHD

    Directory of Open Access Journals (Sweden)

    Heinrich Hartmut


    Full Text Available Abstract Background Although several promising studies on neurofeedback training in Attention Deficit/Hyperactivity Disorder (ADHD have been performed in recent years, the specificity of positive treatment effects continues to be challenged. Methods To evaluate the specificity of a neurofeedback training of slow cortical potentials, a twofold strategy was pursued: First, the efficacy of neurofeedback training was compared to a group training program for children with ADHD. Secondly, the extent of improvements observed in the neurofeedback group in relation to successful regulation of cortical activation was examined. Parents and teachers rated children's behaviour and executive functions before and after treatment. In addition, children underwent neuropsychological testing before and after training. Results According to parents' and teachers' ratings, children of the neurofeedback training group improved more than children who had participated in a group therapy program, particularly in attention and cognition related domains. On neuropsychological measures children of both groups showed similar improvements. However, only about half of the neurofeedback group learned to regulate cortical activation during a transfer condition without direct feedback. Behavioural improvements of this subgroup were moderately related to neurofeedback training performance, whereas effective parental support accounted better for some advantages of neurofeedback training compared to group therapy according to parents' and teachers' ratings. Conclusion There is a specific training effect of neurofeedback of slow cortical potentials due to enhanced cortical control. However, non-specific factors, such as parental support, may also contribute to the positive behavioural effects induced by the neurofeedback training.

  2. Compliance on neuropsychological performance validity testing in patients with borderline personality disorder. (United States)

    Ruocco, Anthony C


    Complaints of cognitive dysfunction are common in patients with borderline personality disorder (BPD), and they are often accompanied by deficits on neuropsychological testing. Prior studies of BPD, however, did not evaluate compliance on neuropsychological performance validity testing, which could partially account for cognitive deficits observed in patients. The aims of the current study were to evaluate the frequency at which patients with BPD show less than adequate compliance on performance validity testing, and whether patients showing less compliance perform lower on standardized neuropsychological measures. Fifty outpatients with BPD completed the Victoria Symptom Validity Test, a 2-alternative, forced-choice recognition test as part of a larger neuropsychological test battery for research on cognitive functioning in BPD. As a group, patients with BPD made more errors and had longer response latencies on seemingly difficult items as compared to healthy individuals. Based on established guidelines for interpretation of performances on the Victoria Symptom Validity Test, 2% of the sample was classified as probably not compliant, 10% questionably compliant, and 88% compliant. Patients with questionably or probably not compliant performances had lower estimated premorbid intellectual functioning and displayed poorer response control on neuropsychological testing than compliant patients. These findings highlight the value of incorporating performance validity testing in neuropsychological studies of patients with BPD and suggest that prior research on the disorder should be interpreted with caution because the results may not be based on valid performances.

  4. Telemedicine and the evaluation of cognitive impairment: the additive value of neuropsychological assessment. (United States)

    Harrell, Kathryn M; Wilkins, Stacy S; Connor, Megan K; Chodosh, Joshua


    The number of people in the United States living with dementia is projected to rise to over 7.1 million in the next 12 years, representing a 40% increase from current levels. This anticipated "dementia tsunami" has led to a recent state and national policy emphasis on early detection, improved care quality, reduced caregiver burden, and increased access to care. The ability to achieve these objectives is limited by few dementia specialists in rural and small communities and the challenges of travel to and within congested urban regions for dementia patients and their caregivers. Telemedicine is one such means for responding to this lack of access to subspecialty assessment and care. We describe our early experiences with this technology applied to neuropsychological assessments, with data from 31 patients. As part of an interdisciplinary dementia care demonstration project, clinical video teleconferencing provides real-time high resolution video interactions between dementia subspecialists in a major metropolitan medical center and patients in 3 outlying clinics located 180, 150, and 100 miles away. Comprehensive neuropsychological assessments, designed to address referral questions related to neurocognitive disorders via clinical video teleconferencing, are conducted as one component of interdisciplinary care. Eighty-seven percent of patients referred for neuropsychological assessment had an inaccurate neurocognitive diagnosis at the time of referral. Unmet and unrecognized mental health treatment needs were identified in over 77% of patients. In addition, acceptance was good for patients, caregivers, and clinicians. Teleneuropsychology is proving to be an excellent resource for clarifying cognitive and psychiatric diagnoses, and integrating individual strengths, weaknesses, and preferences into treatment and care plans used by other health care providers, patients, and caregivers.

  5. Lying in neuropsychology. (United States)

    Seron, X


    The issue of lying occurs in neuropsychology especially when examinations are conducted in a forensic context. When a subject intentionally either presents non-existent deficits or exaggerates their severity to obtain financial or material compensation, this behaviour is termed malingering. Malingering is discussed in the general framework of lying in psychology, and the different procedures used by neuropsychologists to evidence a lack of collaboration at examination are briefly presented and discussed. When a lack of collaboration is observed, specific emphasis is placed on the difficulty in unambiguously establishing that this results from the patient's voluntary decision. Copyright © 2014.

  6. Patients with epilepsy and patients with psychogenic non-epileptic seizures: video-EEG, clinical and neuropsychological evaluation. (United States)

    Turner, Katherine; Piazzini, Ada; Chiesa, Valentina; Barbieri, Valentina; Vignoli, Aglaia; Gardella, Elena; Tisi, Giuseppe; Scarone, Silvio; Canevini, Maria Paola; Gambini, Orsola


    The incidence of psychogenic non-epileptic seizures (PNES) is 4.9/100,000/year and it is estimated that about 20-30% of patients referred to tertiary care epilepsy centers for refractory seizures have both epilepsy and PNES. The purpose of our study is to evaluate psychiatric disorders and neuropsychological functions among patients with PNES, patients with epilepsy associated with PNES and patients with epilepsy. We evaluated 66 consecutive in-patients with video-EEG recordings: 21 patients with epilepsy, 22 patients with PNES and 10 patients with epilepsy associated with PNES; 13 patients were excluded (8 because of mental retardation and 5 because they did not present seizures or PNES during the recording period). All patients with PNES had a psychiatric diagnosis (100%) vs. 52% of patients with epilepsy. Cluster B personality disorders were more common in patients with PNES. We observed fewer mood and anxiety disorders in patients with PNES compared with those with epilepsy. We did not find statistically significant differences in neuropsychological profiles among the 3 patient groups. This study can help to contribute to a better understanding of the impact of PNES manifestations, in addition to the occurrence of seizures, in order to provide patients with more appropriate clinical, psychological and social care.

    Working memory impairment is well established in psychotic disorders. However, the relative magnitude, diagnostic specificity, familiality pattern, and degree of independence from generalized cognitive deficits across psychotic disorders remain unclear. Participants from the Bipolar and Schizophrenia Network on Intermediate Phenotypes (B-SNIP) study included probands with schizophrenia (N=289), psychotic bipolar disorder (N=227), schizoaffective disorder (N=165), their first-degree relatives (N=315, N=259, N=193, respectively), and healthy controls (N=289). All were administered the WMS-III Spatial Span working memory test and the Brief Assessment of Cognition in Schizophrenia (BACS) battery. All proband groups displayed significant deficits for both forward and backward span compared to controls. However, after covarying for generalized cognitive impairments (BACS composite), all proband groups showed a 74% or greater effect size reduction with only schizoaffective probands showing residual backward span deficits compared to controls. Significant familiality was seen in schizophrenia and bipolar pedigrees. In relatives, both forward and backward span deficits were again attenuated after covarying BACS scores and residual backward span deficits were seen in relatives of schizophrenia patients. Overall, both probands and relatives showed a similar pattern of robust working memory deficits that were largely attenuated when controlling for generalized cognitive deficits.

  8. Evaluating reading and metacognitive deficits in children and adolescents with attention deficit hyperactivity disorder. (United States)

    Alvarado, Jesús Ma; Puente, Aníbal; Jiménez, Virginia; Arrebillaga, Lorena


    The reading achievement of children and adolescents with Attention Deficit Hyperactivity Disorder (ADHD) has scarcely been explored in research conducted in the Spanish language and when it has, the results have been contradictory. The focus of the present research is to analyze participants' reading competency and metacognitive strategies as they carry out reading comprehension tasks. The sample was comprised of 187 Argentine schoolchildren aged 9 to 13 years old. 94 constituted the control group and the clinical group consisted of 93 schoolchildren diagnosed with ADHD. The metacognitive assessment was made up of two metacognitive tests, the Reading Awareness Scale (ESCOLA; acronym in Spanish) and a Spanish adaptation of Metacognitive Awareness of Reading Strategies Inventory (MARSI), and one test of reading comprehension, the Evaluation of Reading Processes for Secondary Education Students (PROLEC-SE; acronym in Spanish). Students with ADHD had lower achievement on tests o reading comprehension compared to the control group. Nevertheless, our results suggest their difficulties did not stem from readin comprehension problems, but rather from alterations in their Executive Functions, because when subjects' reading comprehensio was equalized, students with ADHD still exhibited a lower level of Metacognition, particularly when it came to planning.

    Fotiou, Dimitrios; Kaltsatou, Antonia; Tsiptsios, Dimitrios; Nakou, Maria


    This study aimed at evaluating the cholinergic hypothesis in Alzheimer's disease (AD) patients utilizing the pupillometry method, cognitive tests and Hamilton Depression Rating Scale (HAM-D), as well as to examine whether a correlation between cognitive tests and pupillometry exists. Forty-two patients with mean age 69.2 ± 7.0 years and documented AD volunteered to participate in this study, while 33 healthy matched subjects served as controls. All subjects underwent a pupillometric measurement and performed the Wechsler Memory Scale (WMS) and Mini Mental State Examination (MMSE). Also, HAM-D was used to assess the severity of depressive symptoms. The pupillometric parameters studied were (1) latency for the onset of constriction (T1), (2) maximum constriction velocity (VCmax), and (3) maximum constriction acceleration (ACmax). In AD patients MMSE and WMS score were correlated with ACmax (r = -0.409, p mean scores of VCmax and ACmax were significantly decreased in AD patients by 46 % (p < 0.05) and by 47 % (p < 0.05), respectively, as compared to healthy subjects. There was no significant difference between the two groups for HAM-D. Additionally, AD patients showed decreased score in WMS by 40 % (p < 0.05) and in MMSE by 28.5 % (p < 0.05) compared to healthy subjects. Of the indices that were studied VCmax and ACmax are governed mainly by the action of the Parasympathetic Nervous System. The results of this study demonstrated that there is a correlation between cognitive tests and pupillometry in AD patients. Thus, pupillometry could be considered as a sensitive technique for the investigation of cholinergic deficits, which indirectly lead to memory and cognitive disorders in AD patients.

  10. Paranoid schizophrenia versus schizoaffective disorder: Neuropsychological aspects

    Directory of Open Access Journals (Sweden)

    Leposavić Ljubica


    Full Text Available Introduction. Neuropsychological aspects of paranoid schizophrenia have still not been examined enough. These disorders are usually not studied separately, but are included in the studies about schizophrenic patients with positive symptoms. Despite the fact that schizophrenia represents a heterogeneous group of mental disorders, usually it is not separated from schizoaffective disorder in neuropsychological researches. Objective. The essence of this research is to evaluate cognitive functioning of patients with paranoid schizophrenia and schizoaffective disorder by applying neuropsychological tests. Methods. The research included 91 subjects, right handed, from 30 to 53 years old, who were classified into three groups: inpatients with paranoid schizophrenia in remission (n=31, inpatients with schizoaffective disorder in remission (n=30 and healthy subjects (n=30. Results. Both groups of patients showed poorer achievements than healthy subjects in most of the applied tests. Patients with schizoaffective disorder showed global loss of intellectual efficiency, executive dysfunction and compromised visual-construction organization. Patients with paranoid schizophrenia expressed partial loss of intellectual efficiency with verbal IQ and executive functions preserved. Conclusion. In the remission phase, patients with paranoid schizophrenia expressed cognitive disorders in moderate degree, but when it comes to patients with schizoaffective disorder, more massive cognitive deficits were registered.

    studies that compare ADHD to normal control comparison individuals, instead of comparing to control clinical individuals. OBJECTIVE: To compare neuropsychological performance of DSM-IV ADHD adults and clinical control individuals with attention complaints referred for neuropsychological evaluation. METHODS: We conducted a retrospective analysis through the database of a private clinic specialized in neuropsychological evaluation along a two year period. ADHD adults (n = 56; 64.28% male were compared to control individuals from the same sample referred due to inattention (n = 29; 58.62% male, with an age range from 18 to 59 years old. Measures of attention, executive functions and memory were used. RESULTS: Groups were paired by age, schooling level, gender distribution and IQ (p > 0.05. We found no differences regarding performances in attention tasks; however, ADHD individuals showed worse performances in tasks that demand verbal working memory. DISCUSSION: When comparing ADHD adults and control individuals with complaints of attention deficits, the first group presented worse performance only in verbal working memory tasks.

  13. Neuropsychologic outcomes in children with neonatal herpes encephalitis. (United States)

    Engman, Mona-Lisa; Adolfsson, Ingrid; Lewensohn-Fuchs, Ilona; Forsgren, Marianne; Mosskin, Mikael; Malm, Gunilla


    Neonatal herpes simplex virus infection with involvement of the central nervous system is a serious disease with high morbidity, even with acyclovir therapy. The disability includes cerebral palsy and different aspects of cognitive dysfunction which are of utmost importance for the child's future habilitation. We conducted a descriptive cohort study to define neuropsychologic outcomes and determine the relationship between neonatal neuroimaging and neuropsychologic outcomes. Among 267,690 children born in the Stockholm area over 12 years (1989-2000), 14 were diagnosed with neonatal herpes including central nervous system involvement. Nine children were neuropsychologically evaluated. Neonatal herpes virus infection had an even greater impact on cognitive function, speech ability, and attention deficit than anticipated. Relapse leading to deterioration was demonstrated in one child. Social skills were influenced to a lesser degree. Neurodevelopmental outcomes of the children were not well-correlated with extent of cerebral damage as visualized by computed tomography at 7-28 days after onset of signs. Neuropsychologic assessment is essential in the habilitation of the child, and a prerequisite for the evaluation of new treatments and for the assessment of deterioration of cerebral function related to relapses.

    Full Text Available Background. Attention-deficit hyperactivity disorder (ADHD is one of the most common psychiatric disorders among children. The aim of this study was to evaluate risk factors for ADHD in children. Method. In this case-control study, 404 children between 4 and 11 years old were selected by cluster sampling method from preschool children (208 patients as cases and 196 controls. All the participants were interviewed by a child and adolescent psychiatrist to survey risk factors of ADHD. Results. Among cases, 59.3% of children were boys and 38.4% were girls, which is different to that in control group with 40.7% boys and 61.6% girls. The chi-square showed statistically significance (P value < 0.0001. The other significant factors by chi-square were fathers' somatic or psychiatric disease (P value < 0.0001, history of trauma and accident during pregnancy (P value = 0.039, abortion proceeds (P value < 0.0001, unintended pregnancy (P value < 0.0001, and history of head trauma (P value < 0.0001. Conclusions. Findings of our study suggest that maternal and paternal adverse events were associated with ADHD symptoms, but breast feeding is a protective factor.

  15. [The rapid development of child neuropsychology]. (United States)

    Billard, C; Jambaqué, I


    The past few years have seen important progress and new developments in the field of child neuropsychology. Children can exhibit acquired or learning disorders, but in all cases such deficits take place in a developmental trajectory that requires taking into account cerebral maturation and plasticity processes. Child neuropsychology finds its specificity in the perspective of developmental neuropsychology and has close connections with health and education. This article focuses on two pathologies - childhood epilepsies and developmental dyslexia - that highlight the recent progress in this specialty and its perspectives.

  16. A longitudinal study of neuropsychological functioning and academic achievement in children with and without signs of attention-deficit/hyperactivity disorder. (United States)

    Rennie, Brandon; Beebe-Frankenberger, Margaret; Swanson, H Lee


    Attention-deficit/hyperactivity disorder (ADHD) in childhood is associated with poor academic functioning. Deficits in academic functioning have proven to be less responsive to intervention than behavioral deficits in this population, yet the causes of this academic underperformance are not well understood. The purpose of this study is to examine the relationship between ADHD and academic performance in elementary-aged children in a developmental context. To do this, we study important cognitive variables and academic achievement over a three-year timeframe. Based on teacher ratings of ADHD, children were divided into a high symptom group (n = 17) and a low symptom group (n = 34). A thorough battery of cognitive and academic tests was administered at Time 1 and again 2 years later. Cognitive measures focused specifically on working memory and response inhibition. RESULTS indicate that children who have high levels of ADHD signs differ from their low-sign peers in academic achievement and in several cognitive domains. Differences in cognitive functioning show a developmental trend consistent with earlier developmental delays in response inhibition and later delays in working memory. Working memory appears to be particularly important in several academic domains. Importantly, in a longitudinal model, working memory was more predictive of math achievement for students demonstrating signs of ADHD than for those who did not. The relationship between these cognitive variables and academic functioning are explicated in the domains of reading, math, and problem solving.

  17. Neuropsychological Performance and Family History in Children at Age 7 who Develop Adult Schizophrenia or Bipolar Psychosis in the New England Family Studies (United States)

    Seidman, Larry J.; Cherkerzian, Sara; Goldstein, Jill M.; Agnew-Blais, Jessica; Tsuang, Ming T.; Buka, Stephen L.


    Objective Persons developing schizophrenia (SCZ) manifest various premorbid neuropsychological deficits, studied most often by measures of IQ. Far less is known about premorbid neuropsychological functioning in individuals who later develop bipolar psychoses (BP). We evaluated the specificity and impact of family history (FH) of psychosis on premorbid neuropsychological functioning. Methods We conducted a nested case-control study investigating the associations of neuropsychological data systematically collected at age 7 years for 99 adults with psychotic diagnoses (including 45 SCZ and 35 BP) and 101 controls, drawn from the New England cohort of the Collaborative Perinatal Project. A mixed model approach evaluated Full Scale IQ, four neuropsychological factors derived from principal components analysis, and the profile of 10 intelligence and achievement tests, controlling for maternal education, race, and intrafamilial correlation. We used a deviant responder approach (neuropsychologically impaired. Presence of psychosis in first-degree relatives (FH+) significantly increased the severity of childhood impairment for SCZ but not for BP. Conclusions Premorbid neuropsychological deficits are found in a substantial proportion of children who later develop SCZ, especially in the SCZ FH+ subgroup, but less so in BP, suggesting especially impaired neurodevelopment underlying cognition in pre-SCZ children. Future work should assess genetic and environmental factors that explain this FH effect. PMID:22575089

  18. Neuropsychological evaluation of high-risk children from birth to seven years of age. (United States)

    Nogueira Cruz, Judith; Laynez Rubio, Carolina; Cruz Quintana, Francisco; Perez Garcia, Miguel


    High Risk Children (HRC) are those with an increased risk of abnormal development due to any factor affecting neurological growth. Those factors have been the focus of most studies in this area. However, little is known about their long-term consequences over the course of child development. The goal was to study the cognitive, emotional and academic outcomes of 7-year-old children diagnosed as HRC at birth. We compared 14 HRC and 20 healthy children using the WISC-IV, BASC and Brunet-Lezine tests. HRC showed cognitive, emotional and academic deficits compared with healthy children. However, Brunet-Lezine scores obtained over the course of development (6, 12, 18 and 24 months) were not predictive of the children's' current psychological status. Long-term follow-up with HRC should be maintained until 7 years of age, at which point an appropriate treatment should be implemented.

  19. [Neuropsychology and epilepsy]. (United States)

    Campos-Castelló, J; Campos-Soler, S

    The epileptic child has three times more risk of presenting cognitive disorders than other children with no neurological pathology, in accordance with three essential facts: 1. The effect exerted by the actual epilepsy. 2. Any associated previously-existing neuropsychosocial deficits. 3. The side effects of the antiepileptic drug (AED). A certain amount of deterioration is universally accepted, without defining the factors involved in its production, but which are multifactorial according to computer studies. From this point of view, we analyse the relation between neuropsychology and epilepsy in Paediatrics. The relation between epilepsy and behaviour must be seen as an exception and not the rule, unless there are coexisting personality disorders and/or mental deficiency. The cognitive effects of AED depend on the drug, the doses used and on the polypharmacy, and these effects may be both adverse and beneficial. The differences from one drug to another are questionable due to the methodology used in the different studies and it should be remembered that with suitable doses the side effects are generally moderate, and AED monitoring is useful in this case. We recommend the use of MEDDRA assessment to obtain a more reliable definition of side effects, which in turn will allow them to be better evaluated. Scaling time in the introduction of the drug is important, especially with some of the new AED. The mechanisms governing the production of the side effects vary, but both the classical and the new ones, which are well used owing to the greater knowledge we have of their mechanism of action, improve cognitive functioning by controlling the seizures. In infancy, idiopathic cognitive reactions are produced. In childhood, the main disorders are a diminished reaction and information processing time with alterations affecting memory, attention and language. Epilepsy is associated to a number of different, generally mild, cognitive problems. The age of onset of epilepsy

  20. White matter integrity assessed by diffusion tensor tractography in a patient with a large tumor mass but minimal clinical and neuropsychological deficits. (United States)

    Bozzali, Marco; MacPherson, Sarah E; Cercignani, Mara; Crum, William R; Shallice, Tim; Rees, Jeremy H


    Diffusion tensor imaging (DTI) tractography and image registration were used to investigate a patient with a massive left-sided brain tumor, whose size was largely disproportionate to his subtle neurological deficits. MRI was obtained from the patient and his healthy identical twin, who acted as anatomical reference for DTI and as a control for quantitative measures. To compensate for the patient's altered anatomy, seed and way points for probabilistic tractography were drawn on the color-coded direction maps of the healthy twin. Registration, based on the combination of b0-images, T2-weighted and T1-weighted images, was used to identify the corresponding regions in the patient. The corticospinal tract (CST), the superior longitudinal fasciculus (SLF), and the cingulum bundle (CB) showed displaced anatomy. A significant difference was found between fractional anisotropy distribution along the left SLF and CB, but not along the CST. These findings fit well with the patient's substantial preservation of his motor abilities, while abnormalities of the SLF and CB could explain the subtle but detectable cognitive deficits.

  1. Neuropsychological alterations in mercury intoxication persist several years after exposure (United States)

    Zachi, Elaine Cristina; Taub, Anita; Faria, Marcília de Araújo Medrado; Ventura, Dora Fix


    Elemental mercury is a liquid toxic metal widely used in industry. Occupational exposure occurs mainly via inhalation. Previously, neuropsychological assessment detected deficits in former workers of a fluorescent lamp plant who had been exposed to elemental mercury vapor and were away from exposure for several years at the time of examination. Objectives The purpose of this work was to reexamine these functions after 18 months in order to evaluate their progression. Methods Thirteen participants completed tests of attention, inhibitory control, verbal/visual memory, psychomotor speed, verbal fluency, visuomotor ability, executive function, semantic knowledge, and depression and anxiety inventories on 2 separate occasions. Results At baseline, the former workers indicated slower psychomotor and information processing speed, verbal spontaneous recall memory impairment, and increased depression and anxiety symptoms compared to controls (Precovery of functions, the neuropsychological effects related to mercury exposure are found to persist for many years.

  2. Neuropsychological functioning following cardiac transplant in Danon disease. (United States)

    Salisbury, David; Meredith, Katherine


    To present a unique case involving a 31-year-old male with Danon disease (diagnosed at 14) who received cardiac transplant and subsequent cardiac re-transplant. Brief report/case study. Serial neuropsychological assessment across a 23-year span along with a review of school records and prior psychoeducational assessment. A consistent pattern of higher level cognitive impairment from childhood through adulthood was found. This pattern is interpreted in light of the sparse literature regarding cognitive and adaptive functioning related to Danon disease. The noteworthy aspects of this case include the preservation of some academic abilities and an unexpected level of functional independence given cognitive concerns. This case study further explores the nature of the deficits related to Danon disease and highlights the benefits of neuropsychological evaluation to guide functional interventions and maximize level of independence across the life span.

  3. Trait or state? A longitudinal neuropsychological evaluation and fMRI study in schizoaffective disorder. (United States)

    Madre, Merce; Radua, Joaquim; Landin-Romero, Ramon; Alonso-Lana, Silvia; Salvador, Raimond; Panicali, Francesco; Pomarol-Clotet, Edith; Amann, Benedikt L


    Schizoaffective patients can have neurocognitive deficits and default mode network dysfunction while being acutely ill. It remains unclear to what extent these abnormalities persist when they go into clinical remission. Memory and executive function were tested in 22 acutely ill schizoaffective patients; they also underwent fMRI scanning during performance of the n-back working memory test. The same measures were obtained after they had been in remission for ≥ 2 months. Twenty-two matched healthy individuals were also examined. In clinical remission, schizomanic patients showed an improvement of memory but not of executive function, while schizodepressive patients did not change in either domain. All schizoaffective patients in clinical remission showed memory and executive impairment compared to the controls. On fMRI, acutely ill schizomanic patients had reversible frontal hypo-activation when compared to clinical remission, while activation patterns in ill and remitted schizodepressive patients were similar. The whole group of schizoaffective patients in clinical remission showed a failure of de-activation in the medial frontal gyrus compared to the healthy controls. There was evidence for memory improvement and state dependent changes in activation in schizomanic patients across relapse and remission. Medial frontal failure of de-activation in remitted schizoaffective patients, which probably reflects default mode network dysfunction, appears to be a state independent feature of the illness.

    F Hoseini


    Full Text Available To investigate the relationship oxygen deficit stress on germination indicators and seedling growth of five wheat cultivars in laboratory condition, an experiment with Randomized Complete Block design in factorial arrangement with three replications was conducted in 2008. The treatments consisted of five wheat cultivars (Chamran, Flat, Roshan, Stare and Shole as A factor, and two oxygen level (normal seed and seed under oxygen deficit stress conditions as B factor in each of these figures was done. Results showed that oxygen deficit stress caused to decrease for various cultivars germination percentage, germination rate, allometric coefficient, seed vigor index and other germination indicators. Therefore, this test as a suitable method for determining the quality of various seed lot can be used in the water logging condition. In addition, among different cultivars characterized that Roshan cultivar was more resistant to oxygen deficit stress than Chamran, Flat and Star cultivars. Although Chamran cultivar is common cultivar in Khouzestan, but of look most germination indicators arranged as weak seed class. The highest correlation coefficients among the tested cultivars have been related to seed vigor with seedling length and dry weight of radicle with seedling with 0.92 and 0.90, respectively.



    Byrd, Dani; Harris, Katherine S.


    An understanding of the relationship of speech and language symptoms to lesions in the frontal region of the dominant hemisphere depends on a fuller description of the speech phenomena than can be provided by transcriptional or acoustic investigation alone. This paper provides examples of how articulatory movement tracking can aid in describing apraxic speech deficits.

  6. Neuropsychological performance in patients with subcortical stroke

    Directory of Open Access Journals (Sweden)

    Silviane Pinheiro Campos de Andrade


    Full Text Available Vascular cognitive impairment (VCI is characterized by cognitive compromise predominantly of executive dysfunction. OBJECTIVES: To assess cognitive functions in VCI, focusing on executive functions, to observe functional losses in relation to activities of daily living (ADLs and to detect early symptoms prior to the onset of dementia. METHODS: We evaluated healthy subjects matched for gender, education and age to patients with diagnosis of subcortical vascular disease who had a stroke classified into three groups: 1 vascular lesions and no impairment; 2 vascular cognitive impairment with no dementia (VCIND; 3 vascular dementia (VaD. RESULTS AND DISCUSSION: The performance on neuropsychological tests differed among groups, worsening with increased impairment level. The probable VaD group demonstrated impaired performance in memory, processing speed and verbal production, while the VCIND group showed attention deficits. CONCLUSION: Impairment in executive functions and difficulties in ADLs allow us to differentiate levels of impairment in groups of subcortical vascular disease.

  7. History of Neuropsychology Through Epilepsy Eyes


    Loring, David W.


    In the 19th century, Hughlings Jackson relied on clinical history, seizure semiology, and the neurologic examination as methods for seizure localization to inform the first epilepsy surgeries. In the 20th century, psychological and neuropsychological tests were first employed as both diagnostic and prognostic measures. The contemporary practice of epilepsy evaluation and management includes neuropsychology as a critical component of epilepsy care and research, and epilepsy and neuropsychology...

  8. Digitally translated Self-Administered Gerocognitive Examination (eSAGE): relationship with its validated paper version, neuropsychological evaluations, and clinical assessments. (United States)

    Scharre, Douglas W; Chang, Shu Ing; Nagaraja, Haikady N; Vrettos, Nicole E; Bornstein, Robert A


    The original paper Self-Administered Gerocognitive Examination (SAGE) is a valid and reliable cognitive assessment tool used to identify individuals with mild cognitive impairment (MCI) or early dementia. We evaluated identical test questions in a digital format (eSAGE) made for tablet use with the goals of calibrating it against SAGE and establishing its association with other neuropsychological tests and clinical assessments of cognitive impairment. Subjects aged 50 and over who had taken SAGE were recruited from community and clinic settings. Subjects were randomly selected to participate in a clinical evaluation including neuropsychological evaluations. SAGE and eSAGE were administered using a crossover design. Subjects were identified as dementia, MCI, or normal based on standard clinical criteria. Associations were investigated using Spearman correlations, linear regression, and sensitivity and specificity measures. Of the 426 subjects screened, 66 completed the evaluation. eSAGE score correlation to a battery of neuropsychological tests was 0.73 (p digital format. Spearman correlation of SAGE versus eSAGE was 0.88 (p digital proficiency), eSAGE scores are lower by an average of 0.83 points (p = 0.029). With a score 16 and higher being classified as normal, eSAGE had 90% specificity and 71% sensitivity in detecting those with cognitive impairment from normal subjects. Tablet-based eSAGE shows a strong association with the validated paper SAGE and a neuropsychological battery. It shows no scale bias compared to SAGE. Both have the advantage of self-administration, brevity, four interchangeable forms, and high sensitivity and specificity in detecting cognitive impairment from normal subjects. Their potential widespread availability will be a major factor in overcoming the many obstacles in identifying early cognitive changes., NCT02544074 . Registered on 18 March 2015.

  9. Cerebellar agenesis: clinical, neuropsychological and MR findings. (United States)

    Timmann, D; Dimitrova, A; Hein-Kropp, C; Wilhelm, H; Dörfler, A


    Cases of cerebellar agenesis are rare. The degree of motor impairment is a matter of discussion. It has been claimed that normal motor function can be observed. Detailed descriptions of neurological findings, however, are lacking. Neuropsychological testing in cerebellar agenesis is of additional interest based on recent findings of impaired non-motor functions in cerebellar disease. The case of an elderly woman with cerebellar agenesis is presented. 3D-MR imaging was used to confirm the diagnosis. Neurological and neuropsychological examination was performed including video documentation (see the authors' own website). To assess deficits of motor learning eyeblink conditioning was investigated. Neurological examination revealed mild to moderate signs of cerebellar dysarthria, upper and lower limb ataxia and ataxia of stance and gait. Motor learning was affected as shown by inability to acquire conditioned eyeblink responses. In addition, neuropsychological testing disclosed mild to moderate deficits in IQ, planning behavior, visuospatial abilities, memory and attention. Cerebellar ataxia, although clearly present, was less than one would expect in almost complete absence of the cerebellum. Neuropsychological deficits, on the other hand, appeared to be more marked than one would expect in cerebellar disease. No conclusion, however, could be drawn whether impaired cognitive development and neuropsychological test performance were directly related to lack of cerebellar function, or caused by impaired motor development and performance.

  10. Ayahuasca in adolescence: a neuropsychological assessment. (United States)

    Doering-Silveira, Evelyn; Lopez, Enrique; Grob, Charles S; de Rios, Marlene Dobkin; Alonso, Luisa K; Tacla, Cristiane; Shirakawa, Itiro; Bertolucci, Paulo H; Da Silveira, Dartiu X


    The purpose of the study was to evaluate neuropsychologically adolescents who use ayahuasca in a religious context. A battery of neuropsychological tests was administered to adolescents who use ayahuasca. These subjects were compared to a matched control group of adolescents who did not use ayahuasca. The controls were matched with regards to sex, age, and education. The neuropsychological battery included tests of speeded attention, visual search, sequencing, psychomotor speed, verbal and visual abilities, memory, and mental flexibility. The statistical results for subjects from matched controls on neuropsychological measures were computed using independent t-tests. Overall, statistical findings suggested that there was no significant difference between the two groups on neuropsychological measures. Even though, the data overall supports that there was not a difference between ayahuasca users and matched controls on neuropsychological measures, further studies are necessary to support these findings.

  11. Private pediatric neuropsychology practice multimodal treatment of ADHD: an applied approach. (United States)

    Beljan, Paul; Bree, Kathleen D; Reuter, Alison E F; Reuter, Scott D; Wingers, Laura


    As neuropsychologists and psychologists specializing in the assessment and treatment of pediatric mental health concerns, one of the most prominent diagnoses we encounter is attention-deficit hyperactivity disorder (ADHD). Following a pediatric neuropsychological evaluation, parents often request recommendations for treatment. This article addresses our approach to the treatment of ADHD from the private practice perspective. We will review our primary treatment methodology as well as integrative and alternative treatment approaches.

  12. Nocturnal hypoxia and neuropsychological variables. (United States)

    Berry, D T; Webb, W B; Block, A J; Bauer, R M; Switzer, D A


    Hypoxia is a well known cause of brain dysfunction. Neuropsychological impairments have been observed in normal subjects experiencing hypoxia iatrogenically as well as in patients with chronic lung disease. Recent investigations have demonstrated significant nocturnal hypoxia in subjects with sleep-disordered breathing. In the present study, heavy-snoring males, a group known to experience frequent episodes of sleep-disordered breathing received neuropsychological testing and a night of continuous monitoring of respiratory parameters. Partial correlations, controlling for age, weight, and education, indicated reliable relationships between nocturnal hypoxia and measures of general intelligence, verbal and nonverbal memory, and expressive verbal fluency. It is proposed that heavy-snoring males may potentially serve as a population in which to model the neurobehavioral effects of hypoxia. Further research in subjects with sleep-disordered breathing may help clarify the extent of the possible cognitive deficits as well as point out possible ameliorative treatments.

  13. The relationship between initial physical examination findings and failure on objective validity testing during neuropsychological evaluation after pediatric mild traumatic brain injury. (United States)

    Provance, Aaron J; Terhune, E Bailey; Cooley, Christine; Carry, Patrick M; Connery, Amy K; Engelman, Glenn H; Kirkwood, Michael W


    The symptomatology after mild traumatic brain injury (mTBI) is complex as symptoms are subjective and nonspecific. It is important to differentiate symptoms as neurologically based or caused by noninjury factors. Symptom exaggeration has been found to influence postinjury presentation, and objective validity tests are used to help differentiate these cases. This study examines how concussed patients seen for initial medical workup may present with noncredible effort during follow-up neuropsychological examination and identifies physical findings during evaluation that best predict noncredible performance. A portion of pediatric patients will demonstrate noncredible effort during neuropsychological testing after mTBI, predicted by failure of certain vestibular and cognitive tests during initial examination. Retrospective cohort. Level 4. Participants (n = 80) underwent evaluation by a sports medicine physician ≤3 months from injury, were subsequently seen for a neuropsychological examination, and completed the Medical Symptom Validity Test (MSVT). Variables included results of a mental status examination (orientation), serial 7s examination, Romberg test, and heel-to-toe walking test. The primary outcome variable of interest was pass/fail of the MSVT. Of the participants, 51% were male and 49% were female. Eighteen of 80 (23%) failed the MSVT. Based on univariable logistic regression analysis, the outcomes of the Romberg test (P = 0.0037) and heel-to-toe walking test(P = 0.0066) were identified as significant independent predictors of MSVT failure. In a multivariable model, outcome of Romberg test was the only significant predictor of MSVT failure. The probability of MSVT failure was 66.7% (95% CI, 33.3% to 88.9%) when a subject failed the Romberg test. A meaningful percentage of pediatric subjects present evidence of noncredible performance during neuropsychological examination after mTBI. Initial examination findings in some cases may represent symptom

  14. Neuropsychology in Japan: history, current challenges, and future prospects. (United States)

    Sakamoto, Maiko


    The purpose of this special issue was to describe the cross-cultural differences in neuropsychology throughout the world. The current state of neuropsychology in Japan is discussed in this manuscript. Information on six topics, including (1) the history of Japanese neuropsychology, (2) licensure system, (3) job opportunities, (4) neuropsychological clinical services, (5) neuropsychological tests, and (6) neuropsychological research, was gathered via literature searches, official organization websites, and personal communication with clinical psychologists and other professionals in Japan. Neuropsychology reached Japan from the west in the late 1800s, a period of rapid political and social modernization. Professional associations were founded in the 1960s and 1970s and continued to grow. The need for neuropsychological assessment in Japan is growing; however, credential requirements for neuropsychologists have not yet been established. To practice clinical psychology in Japan, one must obtain a Master's degree and pass a licensure examination that is administered by a private professional foundation. Clinical psychologists often conduct neuropsychological tests; however, they have little training in neuropsychological assessment. While many western neuropsychological tests have been translated into Japanese and are used in clinical settings, the majority of translated tests have not been standardized and their psychometric properties remain poorly understood. Standardization and development of normative data in Japan is warranted. Given that needs for neuropsychological services are increasing, it is essential for clinical psychologists in Japan to improve their skills in neuropsychological evaluations. Japanese graduate schools must work to establish neuropsychology programs to educate and train clinical neuropsychologists.

  15. Neuropsychological assessment in kidney and liver transplantation candidates. (United States)

    Lacerda, S S; Guimaro, M S; Prade, C V; Ferraz-Neto, B H; Karam, C H; Andreoli, P B A


    Chronic renal and liver diseases are associated with cognitive and intellectual impairment, which can be irreversible even after kidney or liver transplantation. We sought to investigate the presence of cognitive deficits in organ transplantation candidates. From May 2005 to March 2006, 35 organ transplantation candidates, of mean age 46.71 (+/- 13.01) years, 54.3% including females and 7.29 (+/- 4.22) years mean formal schooling. Of those, 27 (77%) were renal and 8 (23%), liver transplantation candidates. All subjects underwent a neuropsychological assessment battery designed to evaluate attention performance, executive functions, memory, language, visuaospatial, and intellectual skills. We found impairments in attention performance (attention span [34.3%], sustained attention [76.5%], and divided attention [77.8%]), executive functions (category formation [58.3%], errors [61.5%], and perseverative errors [30.4%]), memory (working memory [57.1%], verbal [37.1%] and visual short-term memory [31.4%], verbal [25.7%] and visual long-term memory [51.4], verbal learning [42.9%], interference susceptibility [42.9%], and verbal recognition memory [20.6%]), language (comprehension [38.1%], and vocabulary [30.8%]), visuaospatial (45.8%), and intellectual skills (50.0%). Neuropsychological (cognitive) deficits in transplant candidates are frequent, regardless of the kind of transplantation. The deficits involve several cognitive skills, such as attentional processes, executive functions, memory, language, visuaospatial, and intellectual skills. Therefore, we concluded that a pretransplant neuropsychological assessment is an important measure to detect impairments and to help understand how these difficulties can interfere with patient self-care before and after transplantation.

  20. Cognitive and neuropsychological evolution in children with anti-NMDAR encephalitis. (United States)

    Matricardi, Sara; Patrini, Mara; Freri, Elena; Ragona, Francesca; Zibordi, Federica; Andreetta, Francesca; Nardocci, Nardo; Granata, Tiziana


    We describe neurological and cognitive/neuropsychological changes from symptom onset in 13 consecutive children (8 females and 5 males; median age 11 years, range 3-17) with anti-NMDAR-encephalitis. We assessed neurological status using the modified Rankin Scale for children and cognitive/neuropsychological status using a standardized battery that was administered serially in 10 prospective patients, and at latest follow-up in three retrospective patients diagnosed before study initiation. Symptom onset was marked by neurological or psychiatric/behavioural manifestations, which became severe but regressed at variable rates after starting immunotherapy. The 10 prospective patients were able to undergo first standardized cognitive/neuropsychological assessment a median of 3 months (range 1-12) after symptom onset: they had extensive deficits, although severity varied. Subsequent assessment showed marked improvements although the timescale varied. At latest evaluation (median 31 months, range 3-112, after symptom onset), seven patients had no neurological disability, five had improved substantially, and one had persistent behavioural problems. Latest cognitive/neuropsychological assessment in 11 patients with at least a year of follow-up showed normal general intellectual abilities, but over half had residual deficits indicating frontal lobe dysfunction. All patients had resumed normal activities. Our findings suggest that early installation of immunotherapy results in good long-term recovery in most paediatric patients with anti-NMDAR-encephalitis, however, recovery is incomplete and the disease leaves subtle lasting defects that impact quality of life, social relationships, and academic achievement.

  2. Neuropsychological Profiles of Written Expression Learning Disabilities Determined by Concordance-Discordance Model Criteria. (United States)

    Fenwick, Melanie E; Kubas, Hanna A; Witzke, Justin W; Fitzer, Kim R; Miller, Daniel C; Maricle, Denise E; Harrison, Gina L; Macoun, Sarah J; Hale, James B


    Children with specific learning disabilities (SLD) have disparate neuropsychological processing deficits that interfere with academic achievement in spelling, writing fluency, and/or written expression (WE). Although there are multiple potential causes of WE SLD, there is a paucity of research exploring this critical academic skill from a neuropsychological perspective. This study examined the neuropsychological profiles of WE SLD subtypes defined using the concordance-discordance model (C-DM) of SLD identification. Participants were drawn from a sample of 283 children (194 boys, 89 girls) aged 6 years to 16 years old (M(age) = 9.58 years, SD = 2.29 years) referred for comprehensive neuropsychological evaluations in school settings and subsequently selected based on C-DM determined spelling, writing fluency, and WE SLD. WE SLD subtypes differed on several psychomotor, memory, and executive function measures (F range = 2.48-5.07, p range = .049 to <.001), suggesting that these children exhibit distinct patterns of neuropsychological processing strengths and weaknesses. Findings have relevance for differential diagnosis of WE subtypes, discriminating WE SLD subtypes from low WE achievement, and developing differentiated evidence-based instruction and intervention for children with WE SLD. Limitations and future research will be addressed.

  3. Neuropsychological performance in patients with schizophrenia and controls as a function of cigarette smoking status (United States)

    Wing, Victoria C.; Bacher, Ingrid; Sacco, Kristi A.; George, Tony P.


    Schizophrenia is associated with many neurocognitive deficits, some of which are improved by nicotine and cigarette smoking. To better understand the relationship between smoking and cognitive function in schizophrenia, cross-sectional assessment of neuropsychological performance as a function of smoking status (smoker or non-smoker) and smoking history (current, former or never-smoker) in clinically-stable outpatients with schizophrenia and controls was evaluated. Subjects (N=140) were divided into subgroups on the basis of self-report and biochemical verification of smoking history. Current smokers with schizophrenia (n=38), former smokers with schizophrenia (n=17), never-smokers with schizophrenia (n=12), control smokers (n=31), control former smokers (n=16), and control never-smokers (n=26) were administered a comprehensive neuropsychological battery. Smokers were studied under non-deprivation conditions. Comparison of neuropsychological performance in schizophrenia and control subjects revealed significant main effects of diagnosis. Analysis of the data as a function of smoking history demonstrated that never-smokers with schizophrenia performed the poorest on measures of sustained attention, processing speed and response inhibition, when compared to the other schizophrenia subgroups. Cigarette smoking did not alter neuropsychological performance in controls. Our findings suggest that smoking status and history differentially alters neuropsychological outcomes in schizophrenia compared to non-psychiatric controls, and that never-smokers may present with more severe neurocognitive impairments.

  4. Neuropsychological alterations in mercury intoxication persist several years after exposure

    Directory of Open Access Journals (Sweden)

    Elaine Cristina Zachi

    Full Text Available Abstract Elemental mercury is a liquid toxic metal widely used in industry. Occupational exposure occurs mainly via inhalation. Previously, neuropsychological assessment detected deficits in former workers of a fluorescent lamp plant who had been exposed to elemental mercury vapor and were away from exposure for several years at the time of examination. Objectives: The purpose of this work was to reexamine these functions after 18 months in order to evaluate their progression. Methods: Thirteen participants completed tests of attention, inhibitory control, verbal/visual memory, psychomotor speed, verbal fluency, visuomotor ability, executive function, semantic knowledge, and depression and anxiety inventories on 2 separate occasions. Results: At baseline, the former workers indicated slower psychomotor and information processing speed, verbal spontaneous recall memory impairment, and increased depression and anxiety symptoms compared to controls (P<0.05. Paired comparisons of neuropsychological functioning within the exposed group at baseline and 1.5 years later showed poorer immediate memory performance (P<0.05. There were no differences on other measures. Conclusions: Although the literature show signs of recovery of functions, the neuropsychological effects related to mercury exposure are found to persist for many years.

  5. Auditory based neuropsychology in neurosurgery. (United States)

    Wester, Knut


    In this article, an account is given on the author's experience with auditory based neuropsychology in a clinical, neurosurgical setting. The patients that were included in the studies are patients with traumatic or vascular brain lesions, patients undergoing brain surgery to alleviate symptoms of Parkinson's disease, or patients harbouring an intracranial arachnoid cyst affecting the temporal or the frontal lobe. The aims of these investigations were to collect information about the location of cognitive processes in the human brain, or to disclose dyscognition in patients with an arachnoid cyst. All the patients were tested with the DL technique. In addition, the cyst patients were subjected to a number of non-auditory, standard neuropsychological tests, such as Benton Visual Retention Test, Street Gestalt Test, Stroop Test and Trails Test A and B. The neuropsychological tests revealed that arachnoid cysts in general cause dyscognition that also includes auditory processes, and more importantly, that these cognition deficits normalise after surgical removal of the cyst. These observations constitute strong evidence in favour of surgical decompression.

  6. Neuropsychological assessment in HTLV-1 infection: a comparative study among TSP/HAM, asymptomatic carriers, and healthy controls. (United States)

    Silva, M T T; Mattos, P; Alfano, A; Araújo, A Q-C


    Human T cell lymphotropic virus type 1 (HTLV-I) can cause tropical spastic paraparesis/HTLV-1 associated myelopathy (TSP/HAM) and adult T cell leukaemia/lymphoma. More recently other diseases such as isolated peripheral polyneuropathy, myopathy, artropathy, and uveitis have been associated with this retrovirus. Only a few uncontrolled studies, without necessary exclusion criteria, have described mild cognitive deficits among TSP/HAM patients. To further clarify this the authors evaluated, through neuropsychological testing patients with TSP/HAM and asymptomatic infected carriers, comparing both groups with healthy controls. To verify the presence of cognitive deficits among TSP/HAM patients and asymptomatic HTLV-1 infected carriers. In addition, the authors aimed to investigate if these deficits correlated with the degree of motor impairment in TSP/HAM patients. From a cohort of 501 HTLV-1 infected people the authors selected, according to predefined inclusion and exclusion criteria, 40 asymptomatic HTLV-1 carriers and 37 TSP/HAM patients. Neuropsychological testing was blindly performed in both groups and their scores were compared with those obtained from controls. Both the HTLV-1 carrier group and the group of patients with TSP/HAM exhibited a lower performance in neuropsychological tests when compared with controls. Asymptomatic infected carriers and TSP/HAM patients did not differ in their cognitive results. Also, there was no relation between the degree of motor disability and cognitive deficits in the TSP/HAM group. Psychomotor slowing and deficits in the some domains characterised the neuropsychological impairment in HTLV-1 infection: verbal and visual memory, attention and visuomotor abilities. TSP/HAM as well as asymptomatic infection can be associated with mild cognitive deficits. This finding, if confirmed by further studies, will permit the inclusion of cognitive impairment among the neurological manifestations of HTLV-1.

  7. History of Neuropsychology Through Epilepsy Eyes (United States)

    Loring, David W.


    In the 19th century, Hughlings Jackson relied on clinical history, seizure semiology, and the neurologic examination as methods for seizure localization to inform the first epilepsy surgeries. In the 20th century, psychological and neuropsychological tests were first employed as both diagnostic and prognostic measures. The contemporary practice of epilepsy evaluation and management includes neuropsychology as a critical component of epilepsy care and research, and epilepsy and neuropsychology have enjoyed a very special and synergistic relationship. This paper reviews how epilepsy has shaped the practice of neuropsychology as a clinical service by asking critical questions that only neuropsychologists were in a position to answer, and how clinical care of epilepsy patients has been significantly improved based on neuropsychology's unique contributions.

  11. An evaluation of the pharmacokinetics of methylphenidate for the treatment of attention-deficit/ hyperactivity disorder. (United States)

    Frölich, Jan; Banaschewski, Tobias; Döpfner, Manfred; Görtz-Dorten, Anja


    Methylphenidate (MPH) plays a principal role in the multimodal treatment of attention-deficit/hyperactivity disorder (ADHD). Controlled studies have demonstrated an effective reduction in the core symptoms of the disorder following MPH therapy, although long-term studies also demonstrate that the therapeutic benefits dissipate in the absence of combined psychosocial interventions. This review article focuses on the pharmacological characteristics of MPH, examining its effects on brain metabolism and the neurotransmitter system. Neuropsychological and clinical effects of different immediate and extended release MPH formulations are discussed to aid clinicians in choosing the appropriate formulation. The drug's addictive potency and abuse potential is also discussed. Data came from a literature search of relevant studies performed using the PubMed database up to June 2013. MPH is effective in the treatment of the core symptoms of ADHD. Considerable clinical expertise is required to identify an individually well-adapted dosage which will produce the optimal clinical effects with potential side effects minimized. Due to low adherence to medication, especially in adolescents, motivation to treatment and attentive clinical monitoring is mandatory, as is the consideration of risks of abuse or the presence of a comorbid addictive disorder.

  12. Preoperative neuropsychological presentation of patients with refractory frontal lobe epilepsy. (United States)

    Patrikelis, Panayiotis; Gatzonis, Stylianos; Siatouni, Anna; Angelopoulos, Elias; Konstantakopoulos, George; Takousi, Maria; Sakas, Damianos E; Zalonis, Ioannis


    This study investigated whether certain cognitive deficits are associated with frontal lobe epilepsy (FLE) aiming to contribute with localization data to the preoperative assessment of epilepsy surgery candidates. We evaluated 34 patients with refractory FLE, 37 patients with refractory medial temporal lobe epilepsy (MTLE), and 22 healthy individuals in attention, psychomotor speed, motor function, verbal memory span, verbal fluency, response inhibition/interference, concept formation and set shifting, anticipation and planning, global memory. Neuropsychological performances of FLE and MTLE were similar, with the only exception the WCST-number of categories index, measuring mental flexibility, in which MTLE patients performed significantly worse than FLE patients. Left-FLE patients presented more perseverative responding compared to both other patient groups and healthy controls (HCs), while left-MTLE patients showed worse sorting abilities than the other epilepsy groups. Our findings suggest a weak cognitive differentiation between FLE and MTLE, probably attributed to the intricate nature of fronto-temporal connectivity frequently resulting in overlapping deficits as well as the confounding effects of seizure-related variables. In clinical practice, a highly individualized (idiographic) neuropsychological approach along with the inclusion of concurrent EEG recordings (e.g., interictal coupling) may be of help for neuropsychologists in identifying FLE patients from those with medial temporal pathology presenting frontal dysfunction as a secondary cognitive symptom.

  13. Driving-Related Neuropsychological Performance in Stable COPD Patients

    Directory of Open Access Journals (Sweden)

    Foteini Karakontaki


    Full Text Available Background. Cognitive deterioration may impair COPD patient’s ability to perform tasks like driving vehicles. We investigated: (a whether subclinical neuropsychological deficits occur in stable COPD patients with mild hypoxemia (PaO2 > 55 mmHg, and (b whether these deficits affect their driving performance. Methods. We recruited 35 stable COPD patients and 10 normal subjects matched for age, IQ, and level of education. All subjects underwent an attention/alertness battery of tests for assessing driving performance based on the Vienna Test System. Pulmonary function tests, arterial blood gases, and dyspnea severity were also recorded. Results. COPD patients performed significantly worse than normal subjects on tests suitable for evaluating driving ability. Therefore, many (22/35 COPD patients were classified as having inadequate driving ability (failure at least in one of the tests, whereas most (8/10 healthy individuals were classified as safe drivers (P=0.029. PaO2 and FEV1 were correlated with almost all neuropsychological tests. Conclusions. COPD patients should be warned of the potential danger and risk they face when they drive any kind of vehicle, even when they do not exhibit overt symptoms related to driving inability. This is due to the fact that stable COPD patients may manifest impaired information processing operations.

  14. A neuropsychological assessment, using computerized battery tests (CANTAB), in children with benign rolandic epilepsy before AED therapy. (United States)

    Vinţan, M A; Palade, S; Cristea, A; Benga, I; Muresanu, D F


    Benign rolandic epilepsy (BRE) is a form of partial idiopathic epilepsy according to the International League Against Epilepsy (ILAE) syndromes classification (1989). Recent studies have identified cases of BRE that do not meet the initial definition of 'benign'; these included reports of cases with specific cognitive deficits. It is still a matter of debate, whether these deficits are due to epilepsy per se, to treatment or other associated factors. The aim of this study was to evaluate if BRE children have cognitive deficits at the onset of their seizures, prior to their participation in any anti-epileptic drug therapy (AED). We performed a neuropsychological assessment of 18 BRE children compared with a corresponding age-matched control group. We used the Cambridge Neuropsychological Test Automated Battery (CANTAB). Subjects were at their first neurological evaluation, before any AED therapy. We assessed: visual memory, induction and executive functions. In our group, the BRE children performed comparably with the control children for the induction and executive functions. Substantial differences were identified for the visual memory subtests: PRM percent correct (t = -2.58, p = 0.01) and SRM percent correct (t = -2.73, p = 0.01). Age of seizure onset had a negative impact on the visual memory subtest performances (PRM mean correct latency). We found significant correlations between the different CANTAB subtests results and characteristics of the centrotemporal spikes (CTS). Our results are consistent with the findings of other similar studies. This form of epilepsy is associated with subtle neuropsychological deficits, present at seizure onset. Neuropsychological deficits identified, suggest a more diffuse brain involvement in the epileptiform process.

  15. International growth of neuropsychology. (United States)

    Ponsford, Jennie


    Twenty-five years ago, the field of neuropsychology was well established in North America, Europe, and Australia, with less presence elsewhere. This article discusses the development of neuropsychology over the last 25 years in other regions. The growth of neuropsychology in Asia, Africa, the Middle East, Central and South America, and New Zealand is reviewed. Sources drawn on include a 2016 edition of The Clinical Neuropsychologist describing the practice of neuropsychology in 18 countries; papers on the profession of neuropsychology in Latin America (Arango-Lasprilla, Stevens, Paredes, Ardila, & Rivera, 2016), the history of neuropsychology in Asia (Lee, Wang, & Collinson, 2016), and neuropsychology in Central America (Judd, 2017); INSNET; and personal communications. There has been tremendous variability in the development of neuropsychology across these regions over the last 25 years. Obstacles to the growth of neuropsychology have included economic constraints on health care provision, limited availability of appropriate assessment and treatment methods, linguistic diversity and illiteracy, stigma toward and/or lack of awareness of neuropsychological disorders, lack of graduate training and clinical supervision, absence of accreditation of neuropsychologists as a clinical profession, poor pay, and diminished visibility of the field within the regional culture. Despite these obstacles, neuropsychological research and practice is establishing itself in these regions and has grown significantly over the last quarter century. Major challenges remain in establishing awareness of the significance of and developing culturally appropriate methods of assessing and rehabilitating cognitive aspects of brain disorders, training programs, recognition as a profession, and dedicated funding for neuropsychology positions.

  16. A critical evaluation of the lateralizing significance of material-specific memory deficits in patients with mesial temporal lobe epilepsy with hippocampal sclerosis. (United States)

    Jeyaraj, Malcolm K; Menon, Ramshekhar N; Justus, Sunitha; Alexander, Aley; Sarma, P Sankara; Radhakrishnan, Kurupath


    To critically assess the value of material-specific memory deficits in lateralizing temporal lobe dysfunction preoperatively, we compared the neuropsychological data of 50 consecutive patients with unilateral mesial temporal lobe epilepsy with hippocampal sclerosis (MTLE-HS; right: 31, left: 19) with those of 50 age- and education-matched healthy control subjects. On case-control comparison, both the subcohorts with left and right MTLE-HS performed poorly on intelligence tests, in addition to individual memory tests. However, comparison of the verbal and visual memory functions between subcohorts with right and left MTLE-HS revealed that learning trials and delayed word list recall were the only tests that hypothesized left temporal lobe dysfunction. We conclude that material-specific memory deficits are largely test driven, but there is a lateralizing role for task-specific deficits in left MTLE-HS. Although neuropsychological data help to define baseline neuropsychological impairment, caution should be exercised in interpreting the lateralizing value of material-specific memory deficits prior to surgery. © 2013.

  17. Neuropsychology in Multiple Sclerosis: A literature review.

    Directory of Open Access Journals (Sweden)

    Rodneys Mauricio Jiménez Morales


    Full Text Available Multiple sclerosis is an inflammatory disease of the central nervous system that is characterized by demyelination and degeneration. The objective of this article is to offer a review of the latest scientific discoveries in the field of neuropsychology in ME. A description is presented of the most frequent neuropsychological manifestations and their probable association with other factors such as: school level, fatigue, disability, cerebral dysfunction, time and clinical form of evolution, as well as depression and other states of mind starting from recent evidences in the scientific community. Also addressed is the development of tests and valid sensitive neuropsychological sets to evaluate cognitive functions. The use of sensitive and specific test facilitates the evaluation of neuropsychological alterations associated to ME, besides other socio-demographic and clinical-evaluative factors to contemplate in the exploration.

  18. The impact of oculomotor functioning on neuropsychological performance in Huntington disease. (United States)

    Carvalho, Janessa O; Long, Jeffrey D; Westervelt, Holly J; Smith, Megan M; Bruce, Jared M; Kim, Ji-In; Mills, James A; Paulsen, Jane S


    Huntington disease (HD) is a neurodegenerative condition with prominent motor (including oculomotor), cognitive, and psychiatric effects. While neuropsychological deficits are present in HD, motor impairments may impact performance on neuropsychological measures, especially those requiring a speeded response, as has been demonstrated in multiple sclerosis and schizophrenia. The current study is the first to explore associations between oculomotor functions and neuropsychological performance in HD. Participants with impaired oculomotor functioning performed worse than those with normal oculomotor functioning on cognitive tasks requiring oculomotor involvement, particularly on psychomotor speed tasks, controlling for covariates. Consideration of oculomotor dysfunction on neuropsychological performance is critical, particularly for populations with motor deficits.

  19. Subtyping Obsessive-Compulsive Disorder: Neuropsychological Correlates

    Directory of Open Access Journals (Sweden)

    Catherine L. Harris


    Full Text Available We administered neuropsychological measures considered sensitive to prefrontal dysfunction (both orbitofrontal and dorsolateral prefrontal neocortex to obsessive-compulsive disorder (OCD patients and control subjects. OCD subjects exhibited performance deficits, in comparison to community controls, on three measures sensitive to orbitofrontal neocortex dysfunction. Contrary to expectation, OCD patients also exhibited performance deficits on measures sensitive to dorsolateral prefrontal neocortex dysfunction. However, distinct neurocognitive profiles emerged when we examined the impact of comorbid schizotypal personality features on neuropsychological test performance. Primary OCD patients displayed impaired performance on measures sensitive to orbitofrontal dysfunction; however, they did not differ from control subjects on tests of dorsolateral function. OCD subjects presenting with schizotypal personality features performed poorly not only on tests sensitive to orbitofrontal dysfunction, but also on tests sensitive to dorsolateral dysfunction. Findings suggest that OCD can be subdivided into clinical subtypes, and distinct prefrontal subsystems may be differentially involved in these subtypes.

    Hydrocephalus in cryptococcal meningoencephalitis is most commonly managed with a ventriculoperitoneal shunt. This study applied cine magnetic resonance imaging (MRI) to evaluate initial disease severity on long-term cerebrospinal fluid (CSF) flow dynamics and associated neuropsychological sequelae in cryptococcal meningoencephalitis patients with and without ventriculoperitoneal shunts. Eighteen human immunodeficiency virus-seronegative cryptococcal meningoencephalitis patients (10 with shunts versus 8 without shunts) were compared with 32 age- and sex-matched healthy volunteers. All subjects underwent complete neurologic examination and neuropsychological testing. Cine MRI was conducted to evaluate CSF flow parameters. Initial CSF laboratory analysis and imaging findings were correlated with present CSF flow parameters and neuropsychological scores. Patients without shunts had higher average flow than controls, suggesting chronic hydrocephalus. Initial Evans ratios and CSF glucose levels were associated with CSF peak velocity and flow. Worsening CSF flow parameters correlated with decreased neuropsychological performance. CSF flow parameter differences between the cryptococcal meningoencephalitis patients both with and without ventriculoperitoneal shunts could be detected by cine MRI and correlated with acute stage disease severity and chronic stage neuropsychological results. Cine MRI is useful for assessing the chronic hydrocephalus that may lead to neuropsychological deficits in cryptococcal meningoencephalitis patients.

  3. Evaluation of neuropsychological symptoms and exposure to benzene, toluene and xylene among two different furniture worker groups in Izmir. (United States)

    Mandiracioglu, Aliye; Akgur, Serap; Kocabiyik, Nesrin; Sener, Ufuk


    This study was conducted to determine whether there was any exposure to toluene, xylene and benzene and to assess the health impact of these solvents on workers in furniture enterprises in Karabaglar, Izmir. This cross-sectional study covered furniture enterprises in Karabaglar, Izmir. This study was comprised of an exposed group consisting of workers engaged in painting and varnishing and therefore exposed either directly or indirectly toluene, xylene and benzene in the workplace and the non-exposed group engaged in other aspects of production. While a total of 261 individuals completed questionnaires, 210 workers agreed to provide blood samples. Blood solvents levels were determined using gas chromatograph at Ege University, Intoxication Research and Application Centre. The modified EUROQUEST questionnaire was used to assess neuropsychological symptoms and neurological and general examination were performed. Occupational and exposure history, demographic and work-related information was collected. In this study of workers, blood toluene and benzene levels were found to be significantly higher among those engaged in painting and varnishing compared to those who perform other tasks. The average blood toluene and benzene concentrations among exposed workers were 6.95 times and 1.64 times respectively higher than those in the nonexposed groups. Smokers and participants who worked in excess of 8 hours/day had higher blood toluene and benzene levels. The most frequently work-related health complaints were back pain, allergies and asthma. No differences were found in the average scores in the neuropsychological symptoms questionnaire between exposed and non-exposed groups. Neurological examination of two individuals with these complaints revealed a loss of reflexes. The workers were unaware that they were being exposed to solvents at work. Tobacco smoke is a major source of internal exposure to benzene. Improving working conditions in furniture work places is a priority.

    Vélez-van-Meerbeke, A; Zamora, I P; Guzmán, G; Figueroa, B; López Cabra, C A; Talero-Gutiérrez, C


    To identify impairment of executive functions (EF) in children with attention deficit hyperactivity disorder (ADHD). A case-control study was performed on a sample of schoolchildren with low socioeconomic levels in Bogota, Colombia. ADHD was diagnosed using the DSM IV checklist and the Behavior Assessment System for Children scale. Children with cognitive deficits were excluded. We evaluated scores from six measurements of executive function (EF). We conducted a bivariate statistical analysis to compare the variables, a multivariate study controlled by sex and age, and a logistic regression analysis. The study sample included 119 children with ADHD and 85 controls, all aged between 6 and 12 years. Controlling by sex, age, and type of school showed that EF measurements in children with ADHD were significantly more impaired than in controls, especially for measurements of verbal and graphic fluency, Rey-Osterrieth Complex Figure, and cognitive flexibility. Comparison of ADHD subgroups showed that results in children with multiple deficits were similar to those in the global ADHD group. Graphic fluency impairment was the sole impairment in cases with only attention deficit or only hyperactivity-impulsivity manifestations. EF measures in children with ADHD revealed more problems, particularly those having to do within planning, inhibition, working memory and cognitive control. Age and sex may affect the degree of EF impairment. Copyright © 2012 Sociedad Española de Neurología. Published by Elsevier Espana. All rights reserved.

  5. Deficits, delays, and distractions: an evaluation of symbolic play and memory in children with autism. (United States)

    McDonough, L; Stahmer, A; Schreibman, L; Thompson, S J


    Two experiments were conducted to evaluate symbolic-deficit and memory-deficit hypotheses to account for the cognitive problems seen in children with autism. Experiment 1 tested imitation, in immediate and deferred conditions, of familiar actions with different sets of objects representing the developmental progression from functional to symbolic play. The results showed that the autism group and both their receptive language and nonverbal IQ-matched controls imitated familiar actions with realistic objects (evidence for functional play) and placeholder objects (evidence for symbolic play) after delays ranging from 24 hr to 3 weeks. Experiment 2 tested familiar three-step event sequences in which a placeholder object was substituted for the second step in half the events. The results showed that the autism group remembered as many of the actions with the placeholder objects as their language-matched controls and as many correctly ordered sequences, a finding that supports a symbolic-delay (rather than deficit) hypothesis. These results were obtained in highly structured test situations and sharply contrast with the impairments seen in children with autism who are observed in naturalistic settings. Two interpretations of these findings are offered. First, structured test settings minimize distractions that typically occur in naturalistic settings that may interfere or disrupt symbolic play in children with autism. Second, the results are consistent with an executive function deficit in that the autistic group demonstrated more knowledge in the test settings than they demonstrate spontaneously in naturalistic ones.

  7. Assessment of stigma associated with attention deficit hyperactivity disorder: Psychometric evaluation of the ADHD Stigma Questionnaire


    Kellison, Ida; Bussing, Regina; Bell, Lindsay; Garvan, Cynthia


    This study evaluated the psychometric properties of the ADHD Stigma Questionnaire (ASQ) among a community sample of 301 adolescents ages 11–19 years at high (n = 192) and low risk (n = 109) for attention deficit hyperactivity disorder (ADHD). Study subjects were drawn from a cohort study assessing ADHD detection and service use. The 26-item ASQ demonstrated good internal consistency. Confirmatory factor analysis using random parceling supported a three factor structure with highly correlated ...

  8. Applications of Technology in Neuropsychological Assessment (United States)

    Parsey, Carolyn M.; Schmitter-Edgecombe, Maureen


    Most neuropsychological assessments include at least one measure that is administered, scored, or interpreted by computers or other technologies. Despite supportive findings for these technology-based assessments, there is resistance in the field of neuropsychology to adopt additional measures that incorporate technology components. This literature review addresses the research findings of technology-based neuropsychological assessments, including computer-, and virtual reality-based measures of cognitive and functional abilities. We evaluate the strengths and limitations of each approach, and examine the utility of technology-based assessments to obtain supplemental cognitive and behavioral information that may be otherwise undetected by traditional paper and pencil measures. We argue that the potential of technology use in neuropsychological assessment has not yet been realized, and continued adoption of new technologies could result in more comprehensive assessment of cognitive dysfunction and in turn, better informed diagnosis and treatments. Recommendations for future research are also provided. PMID:24041037

  9. Neuropsychology in Mexico. (United States)

    Ostrosky Shejet, Feggy; Velez Garcia, Alicia


    This invited paper explores the diverse pathways that have led to the development of neuropsychology in Mexico. The authors conducted a review of the literature and their own experiences to describe the seminal events and people relevant to the development of this area of research and practice. The master's degree is the usual level of educational attainment for those who wish to practice clinical neuropsychology. As of now, there is not a board certification process in neuropsychology, although there is one in clinical psychology. Neuropsychology and other mental health disciplines in Mexico and Latin America have historically been poorly funded, and have lacked optimal means of communication as to research findings and clinical initiatives and standards. However, there is reason to think that this will be improved upon in coming years.

  10. Hemispheric specialization in partial epilepsy role of dichotic listening cv task and central audiological evaluation in the neuropsychological assessment

    Directory of Open Access Journals (Sweden)

    Mauro Muszkat


    Full Text Available We studied 49 patients with partial epilepsy divided into lesional cases (i.e. with lesions on CT scan and non-lesional cases (i.e. without CT scan lesions, in relation to the Wechsler Intelligence Scale subtests (Coding, Digit span, dichotic listening CV task and Central Auditory Test (SSI, PSI. The aim of this paper was to study the hemispheric prevalence in dichotic listening task with regard to cognitive perforamance, as well as the presence or absence of central auditory dysfunction. Lesional cases presented a hemisphere prevalence in dichotic listening task with regard to cognitive performance, as well as the non-lesional cases tend to report the stimuli in the same side of EEC focus. Significant differences were found among the lesional and non lesional cases in relation to the digit span score and Coding subtest in right lesional cases versus right non-lesional cases. Both lesional and non-lesional group showed signs of central auditory dysfunction. We suggest that the dichotic listening and SSI and PSI test can be useful for a best comprehension of asymmetric neuropsychological performance in partial epilepsy.

  11. Neuropsychology in South Africa. (United States)

    Truter, Sharon; Mazabow, Menachem; Morlett Paredes, Alejandra; Rivera, Diego; Arango-Lasprilla, Juan Carlos


    This survey forms part of an international research study conducted in 39 countries and is the first to describe the characteristics of individuals engaged in the practice of neuropsychology in South Africa (SA). The purpose was to analyze the characteristics of individuals working in the profession of neuropsychology in order to understand their background, professional training, current work situation, assessment and diagnostic procedures, rehabilitation techniques, teaching responsibilities, and research activities. Ninety-five professionals working in neuropsychology completed an online survey between July and November 2015. The majority of participants were female and the mean age was 46.97 years. The majority of professions working in neuropsychology have a background in psychology, with additional specialized training and supervised clinical practice. Over half work in private practice and are on average satisfied with their work. Participants identified as clinicians primarily work with TBI and ADHD individuals. The main limitation for the use of neuropsychological instruments is the lack of normative data in SA and the main barrier to the field is the lack of academic training programs. There is a need to improve graduate curriculums, enhance existing clinical training, develop professional certification programs, validate existing neuropsychological tests, and create new, culturally relevant instruments.

  12. Neuropsychological functioning in children with Tourette syndrome (TS). (United States)

    Rasmussen, Carmen; Soleimani, Maryam; Carroll, Alan; Hodlevskyy, Oleksander


    We examined whether children with Tourette syndrome (TS) displayed a unique pattern of neuropsychological deficits on the CANTAB relative to control children. We also looked at whether children with TS and other comorbidities had more neuropsychological impairments than those with uncomplicated TS and how age was related to the profile of neuropsychological deficits in TS. Participants included 38 children with TS (aged 7 to 13 years) and 38 control children (aged 6 to 12 years). All children were administered 8 subtests from the CANTAB and parents and teachers completed the BRIEF rating scale on children in the TS group. Children with TS displayed deficits relative to control children on measures of visual memory, executive functioning, and attention from the CANTAB. Among the TS group, age was negatively correlated with performance on measures of executive functioning, speed of response and working memory. Identifying the pattern of neuropsychological deficits in children with TS on the CANTAB is important for highlighting areas of deficit that can be targeted for intervention and teaching strategies. With further research, the CANTAB may prove to be a useful resource in the assessment and treatment of children with TS.

  13. Selection criteria for internships in clinical neuropsychology. (United States)

    Ritchie, David; Odland, Anthony P; Ritchie, Abigail S; Mittenberg, Wiley


    Criteria used in the evaluation and selection of applicants for clinical neuropsychology internships were identified by a survey of programs that met guidelines for specialty training. The number of internships that offer training with specialization in clinical neuropsychology has more than doubled during the past 10 years. Supervising neuropsychologists from 75 programs replied to the survey, yielding a 72.8% response rate. Clinical experience in neuropsychological assessment, specialization in clinical neuropsychology during graduate education, personal interview, and letters of recommendation were reported to be the most salient selection criteria. Practica that provide experience with flexible or functional systems assessment approaches at university-affiliated or VA (U.S. Department of Veterans Affairs) medical centers and doctoral curricula that follow International Neuropsychological Society/Division 40 course guidelines, with teaching and supervision provided by neuropsychologists, were preferred prerequisites to internship. These results are consistent with selection criteria reported over a decade ago and indicate continued endorsement of the vertically integrated model of education and training outlined by the Houston Conference on Specialty Education and Training in Clinical Neuropsychology.

  14. [Neuropsychological impairment in the early Alzheimer's disease]. (United States)

    Traykov, L; Rigaud, A-S; Cesaro, P; Boller, F


    This analysis is centered on the study of cognitive disorders in Alzheimer's disease (AD), mainly for major neuro-psychological functions. We insist on the heterogeneity of the clinical picture peculiarly in the early stages of the illness, even if the deficits of episodic memory and of attentional/executive capacities are the first to deteriorate, preceding impairment in perceptual and language function and potentially having a substantial impact on the patient's capacity to cope independently. An episodic memory deficit is the hallmark of AD, but it must be stressed that this deficit may take different forms and its origin may be traced back to different cognitive mechanisms. One of the most striking aspects of episodic memory impairment in AD is the rapidity of forgetfulness on which screening and diagnostic tests of AD are based. There is some evidence that the episodic memory deficit in AD is one of learning (encoding and storage) of information rather than to a deficit of retrieval. Furthermore, episodic memory performance in AD depends on the integrity of semantic memory abilities, so giving support to a hierarchical model of organization of human memory. Finally, recent results show that an impairment of conscious recollection is responsible for the poor performance of AD patients in recognition memory. Executive deficits appear predominantly in tasks requiring cognitive flexibility and self-monitoring. With the progression of the disease, additional deficits are observed in the verbal concept formation abilities. These findings might be also very useful in the differential diagnosis between AD and the other cortical and subcortical dementias, as well as in the differentiation between AD and fronto-temporal dementia. We consider that studying early stages of the illness is necessary to delineate the diagnostic signs, to validate the new therapeutic experiments, to predict stages of decline. Recent research suggested that onset of AD is commonly preceded by

  15. A composite neurobehavioral test to evaluate acute functional deficits after cerebellar haemorrhage in rats. (United States)

    McBride, Devin W; Nowrangi, Derek; Kaur, Harpreet; Wu, Guangyong; Huang, Lei; Lekic, Tim; Tang, Jiping; Zhang, John H


    Cerebellar haemorrhage accounts for 5-10% of all intracerebral haemorrhages and leads to severe, long-lasting functional deficits. Currently, there is limited research on this stroke subtype, which may be due to the lack of a suitable composite neuroscoring system specific for cerebellar injury in rodents. The purpose of this study is to develop a comprehensive composite neuroscore test for cerebellar injury using a rat model of cerebellar haemorrhage. Sixty male Sprague-Dawley rats were subjected to either sham surgery or cerebellar haemorrhage. Twenty-four hours post-injury, neurological behaviour was evaluated using 17 cost-effective and easy-to-perform tests, and a composite neuroscore was developed. The composite neuroscore was then used to assess functional recovery over seven days after cerebellar haemorrhage. Differences in the composite neuroscore deficits for the mild and moderate cerebellar haemorrhage models were observed for up to five days post-ictus. Until now, a composite neuroscore for cerebellar injury was not available for rodent studies. Herein, using mild and moderate cerebellar haemorrhage rat models a composite neuroscore for cerebellar injury was developed and used to assess functional deficits after cerebellar haemorrhage. This composite neuroscore may also be useful for other cerebellar injury models.

  16. Evaluation of adult attention deficit hyperactivity disorder in smokers and Maras powder users. (United States)

    Keten, Hamit Sirri; Onay, Hakan; Ersoy, Ozgur; Isik, Oguz; Gencoglan, Salih; Ucer, Huseyin; Celik, Mustafa


    The aim of this study was to evaluate adult attention deficit and hyperactivity disorder (ADHD) in smokers, Maras powder users and non-users of tobacco products by using the Adult Attention Deficit and Hyperactivity Disorder Self-report Scale (ASRS). The study was performed on 446 males presenting to family health centers in Kahramanmara, Turkey. Of 446 participants, 104 were Maras powder users, 133 were smokers and 209 were volunteers not using any tobacco products. Data were collected with a questionnaire composed of questions about socio-demographic features and features of smoking and Maras powder use, and the Fagerström Nicotine Dependence Scale and the ASRS. P attention deficit subscale and 14.30 ± 5.35 for the hyperactivity and impulsivity subscale. Higher rates of the smokers and the Maras powder users had symptoms of ADHD. Considering nicotine may decrease symptoms of ADHD, it can be assumed that the rates of the smokers and Maras powder users with ADHD are higher.

    Loureiro, Paulo Gerson Cayres


    The optimization model actually used to the energy operation planning of the National Interconnected System - NIS has as objective function the minimization of expected total cost operation. To achieve this goal the model provides optimal allocation of hydrothermal resources during the study horizon, employing aggregated subsystems. The deficit marginal cost is a parameter which is explicitly informed to the model, and does a part in the operation total cost calculation being a predominant factor in the service conditions evaluation of national electric energy market, affecting the energy costs and the risk of deficit on NIS. In this work is realized an integral study about the electric energy deficit marginal cost, starting with a historical review, followed by a actualization of your actual value and a propose of a new method for the calculation of deficit marginal cost value. The studies shows the impact of the values found over service conditions to the electric energy market in the energy operation planning, focusing on some usual indicators adopted in studies of the electrical sector.

    The present study investigated differences and associations between cortical perfusion, nigrostriatal dopamine pathway and neuropsychological functions in different stages of Parkinson's disease (PD). We recruited 53 non-demented PD patients divided into four groups according to the Hoehn and Yahr (HY) staging system and 20 healthy controls who were used in the comparison of the neuropsychological findings. Each patient underwent two separate brain single photon emission computed tomography (SPECT) studies (perfusion and dopamine transporter binding) as well as neuropsychological evaluation. Perfusion images of each patient were quantified and compared with a normative database provided by the NeuroGam software manufacturers. Mean values obtained from the cortical areas and neuropsychological measures in the different groups were also compared by analysis of covariance (ANCOVA) controlling for disease duration and educational level. We found cognitive deficits especially in the late PD stages (HY 3, 4 and 5) compared to the early stages (HY 1 and 2) and associations between cognitive decrements and cortical perfusion deterioration mainly in the frontal and posterior cortical areas. Compared with controls, PD patients showed impairments of cognition and cerebral perfusion that increased with clinical severity. Furthermore, we found a significant correlation between the performance on the phonemic fluency task and regional cerebral blood flow (rCBF) in the left frontal lobe. Dopamine transporter binding in the left caudate nucleus significantly correlated with blood flow in the left dorsolateral prefrontal cortex (DLPFC), but not with measures of executive functions. There are significant cognitive and perfusion deficits associated with PD progression, implying a multifactorial neurodegeneration process apart from dopamine depletion in the substantia nigra pars compacta (SNc).

  19. Pediatric neuropsychology: toward subspecialty designation. (United States)

    Baron, Ida Sue; Wills, Karen; Rey-Casserly, Celiane; Armstrong, Kira; Westerveld, Michael


    Clinical neuropsychology is a rapidly expanding field of study in the psychological sciences whose practitioners are expert in the assessment, treatment, and research of individuals with known or suspected central nervous system disease or disorder. Pediatric neuropsychology has emerged as a distinct subspecialty area with related education, training, and clinical expertise for a growing number of neuropsychologists. This paper details the numerous steps taken by two affiliated organizations, the American Board of Clinical Neuropsychology and its membership organization, the American Academy of Clinical Neuropsychology, in the interest of the larger pediatric neuropsychology community and in pediatric neuropsychology subspecialty development.

    Progressive supranuclear palsy (PSP) is a degenerative condition of unknown aetiology that produces an akinetic-rigid form of parkinsonism characterised by early falls, dementia and abnormalities of extraocular movements. The patterns of decreased regional cerebral blood flow and cognitive impairment in PSP compared with normal control have been insufficiently investigated and a limited number of studies have been performed. We evaluated clinical symptoms, functional neuroimaging study using Tc-99m HMPAO SPECT and neuropsychological profiles in patients with PSP. Eleven patients with PSP diagnosed by the clinical criteria of National Institute of Neurological Disorders and Stroke and the Society for PSP (NINDS-SPSP) (mean age: 70.5{+-}5.6 years, educational period: 4.5{+-}4.7 years) and age-matched 10 healthy control subjects (mean age: 68.1{+-}4.5 years, educational period: 6.5{+-}4.1 years) participated in this study were participated. All patients were given a neurologic examination, brain MRI and cerebral perfusion SPECT using Tc-99m HMPAO. We concomittently evaluated several cognitive profiles using the Seoul Neuropsychological Screening Battery. SPM analysis of the SPECT image showed significant perfusion deficits in the left inferior frontal gyrus, left caudate nucleus, left middle frontal gyrus and cingulate gyrus in the patients with PSP compared with age-matched healthy control (uncorrected p<0.01). On neuropsychological assessment, cognitive deficits on verbal and visual memory, word fluency and frontal executive functions were prominent in most patients with PSP compared with healthy control subjects. Our findings suggest that measurement of regional cerebral blood flow by perfusion SPECT and voxel-based SPM analysis with neuropsychological assessment are useful to understanding the correlation between perfusion deficits and abnormal cognitive profiles in patients with PSP.

  1. Developmental disorders: what can be learned from cognitive neuropsychology? (United States)

    Castles, Anne; Kohnen, Saskia; Nickels, Lyndsey; Brock, Jon


    The discipline of cognitive neuropsychology has been important for informing theories of cognition and describing the nature of acquired cognitive disorders, but its applicability in a developmental context has been questioned. Here, we revisit this issue, asking whether the cognitive neuropsychological approach can be helpful for exploring the nature and causes of developmental disorders and, if so, how. We outline the key features of the cognitive neuropsychological approach, and then consider how some of the major challenges to this approach from a developmental perspective might be met. In doing so, we distinguish between challenges to the methods of cognitive neuropsychology and those facing its deeper conceptual underpinnings. We conclude that the detailed investigation of patterns of both associations and dissociations, and across both developmental and acquired cases, can assist in describing the cognitive deficits within developmental disorders and in delineating possible causal pathways to their acquisition.

    Marilene Zimmer


    at summarizing studies on the most commonly used neuropsychological tests in schizophrenia. A systematic literature review was performed on PubMed, MEDLINE (via PubMed and LILACS, from 1995 through 2006. The keywords were cognition and schizophrenia; evaluation and cognition and schizophrenia; functioning and cognition and schizophrenia. A manual research of references in most frequently cited articles was performed, including meta-analysis studies, theoretical reviews, and the Measurement and Treatment Research to Improve Cognition in Schizophrenia. Inclusion criteria were studies on schizophrenia patients that reported use of neuropsychological tests. A review of the most frequently cited tests was performed to check nomenclature, indications, and which were validated for Brazil. A total of 98 studies were identified: 77 empirical studies, eight meta-analyses, six theoretical reviews and seven from the Measurement and Treatment Research to Improve Cognition in Schizophrenia. There were 102 different names of neuropsychological tests; 10 batteries of tests were cited, most of them composed by previously standardized subtests. Of the 77 empirical studies, 22 (28.57% were about validation of instruments or batteries of tests. Of the 10 most frequently cited tests, only three had been validated for Brazil (WCST; Wechsler Adult Intelligence Scale; Mini-Mental Status Examination. These findings show a wide heterogeneity in the selection criteria of neuropsychological tests, disagreement as to the nomenclature, and a certain trend toward creation of new tests and batteries for evaluating cognitive functions. The relevance and characteristics of cognitive impairments in schizophrenia confirm the urgent necessity of specific and standardized identification of neuropsychological evaluation methods for Brazilian patients.

    Alessandro Ghezzo

    Full Text Available Down Syndrome (DS is characterised by premature aging and an accelerated decline of cognitive functions in the vast majority of cases. As the life expectancy of DS persons is rapidly increasing, this decline is becoming a dramatic health problem. The aim of this study was to thoroughly evaluate a group of 67 non-demented persons with DS of different ages (11 to 66 years, from a neuropsychological, neuropsychiatric and psychomotor point of view in order to evaluate in a cross-sectional study the age-related adaptive and neuropsychological features, and to possibly identify early signs predictive of cognitive decline. The main finding of this study is that both neuropsychological functions and adaptive skills are lower in adult DS persons over 40 years old, compared to younger ones. In particular, language and short memory skills, frontal lobe functions, visuo-spatial abilities and adaptive behaviour appear to be the more affected domains. A growing deficit in verbal comprehension, along with social isolation, loss of interest and greater fatigue in daily tasks, are the main features found in older, non demented DS persons evaluated in our study. It is proposed that these signs can be alarm bells for incipient dementia, and that neuro-cognitive rehabilitation and psycho-pharmacological interventions must start as soon as the fourth decade (or even earlier in DS persons, i.e. at an age where interventions can have the greatest efficacy.

  6. Neuropsychological assessment of children with epilepsy and average intelligence using NEPSY II. (United States)

    Zilli, Tiziana; Zanini, Sergio; Conte, Stefania; Borgatti, Renato; Urgesi, Cosimo


    Many studies have shown altered neuropsychological functioning of children with epilepsy even in the absence of intellectual disability, with notable concerns for both patients and their families. Although studies have described the cognitive profiles associated with specific epilepsy syndromes, there is incomplete agreement on the relation between spared and impaired abilities in different cognitive domains and on how deficits in one neuropsychological ability can secondarily affect performance in other cognitive domains. The aim of this study was to investigate the neuropsychological profile and vulnerabilities of children with epilepsy without intellectual disability or borderline intellectual functioning. 23 children aged 7-15 years, with a diagnosis of epilepsy of genetic or unknown cause and average intellectual functioning (IQ >85), were administered all age-appropriate tests of the Italian-language version (Urgesi, Campanella, & Fabbro, 2011) of a comprehensive neuropsychological battery (NEPSY-II: A Developmental Neuropsychological Assessment, Second Edition; Korkman, Kirk, & Kemp, 2007). Their performance was compared with that of a control group matched for gender, age, handedness and education. Children with epilepsy showed significant impairments as compared to the control group in tests of attention and executive functions and sensorimotor skills. Notably, particular difficulties were observed also in social perception tasks that require affect recognition, an ability that has been so far poorly considered in children with epilepsy. The results highlight the importance of performing extensive evaluation of cognitive functions, including social cognition processes, in children with epilepsy with average intelligence in order to design appropriate interventions aimed at minimizing long-term consequences on educational and behavioral outcome.

  7. Attention deficit hyperactivity disorder and substance misuse: an evaluation of causal hypotheses and treatment considerations. (United States)

    Young, Susan; Sedgwick, Ottilie


    Attention deficit hyperactivity disorder (ADHD) is known to co-occur with substance misuse at a high rate. This has important health and legal implications for those with ADHD. Mechanisms that may influence drug use among those with ADHD are discussed and evaluated in this review, including self-medication, behavioral disinhibition, comorbidity, and sensitization. While no one hypothesis is able to explain the complex phenomenon of drug taking behaviors, it is likely that self-medication, disinhibition and comorbidity play a part, with little evidence for sensitization. The development of efficacious treatment is necessary to help those with this debilitating comorbidity, as there are currently few evidence-based interventions.

  8. Neuropsychological performance of recently abstinent alcoholics and cocaine abusers. (United States)

    Beatty, W W; Katzung, V M; Moreland, V J; Nixon, S J


    To examine possible influences of premorbid and comorbid factors on the neuropsychological test performance of recently abstinent (3-5 weeks) drug abusers, we studied 24 alcoholics, 23 cocaine abusers, and 22 healthy controls of comparable age and education. Both alcoholics and cocaine abusers performed significantly more poorly than controls on most measures of learning and memory, problem solving and abstraction and perceptual-motor speed, but the groups did not differ on the measure of sustained attention. Correlational analyses revealed no significant relationships between measures of childhood and residual hyperactivity and neuropsychological performance; scores on the Beck Depression Inventory were related only to performance on the Wisconsin Card Sorting Test. The findings indicate that abuse of cocaine or alcohol is associated with deficits on neuropsychological tests which cannot be attributed to specific premorbid or comorbid factors such as depression or childhood or residual attention deficit disorder.

    Leposavić Ivana


    Full Text Available Previous studies concerned with neuropsychological aspect of delusions, were mainly focused on specific forms of this disorder. Comparatively small number of investigations were concerned with cognitive deficiencies accompanying the delusions. The substance of this study includes the detection of neuropsychological disfunctions in patients with persistent delusion disorder, and in tracing of these cognitive distortions to appropriate brain regions. Besides, characteristics of attribution style in these patients are analysed, from the aspect of their connections with unadjusted localized input for their reasoning system. The investigation is designed as a comparative study. The sample includes: a group of patients with persistent delusion disorder; a group of patients with paranoid schizophrenia; a group of healthy individuals. The participants have been tested by a neuropsychological battery that represents the following cognitive functions: attention, memory, vizuospatial and vizuoconstruction organization, executive ability, verbal divergent thinking. Projective Rorschach's method was used for estimation of attribution style.

    Full Text Available Attention deficit hyperactivity disorder (ADHD is a neurodevelopmental disorder characterized by symptoms of inattention, hyperactivity, and impulsivity. Soft neurological signs (SNS are minor neurological abnormalities in motor performance, and are used as one evaluation method for neurodevelopmental delays in children with ADHD. Our aim is to establish a quantitative evaluation system for children with ADHD. We focused on the arm movement called pronation and supination, which is one such soft neurological sign. Thirty three children with ADHD aged 7–11 years (27 males, six females and twenty five adults participants aged 21–29 years old (19 males, six females participated in our experiments. Our results suggested that the pronation and supination function in children with ADHD has a tendency to lag behind that of typically developing children by several years. From these results, our system has a possibility to objectively evaluate the neurodevelopmental delay of children with ADHD.

    Gro Strømnes Dybedal


    Full Text Available Background: The literature describing neurocognitive function in patients with late-life depression (LLD show inconsistent findings in regard to incidence and main deficits. Reduced information processing speed is in some studies found to explain deficits in higher order cognitive function, while other studies report specific deficits in memory and executive function. Our aim was to determine the characteristics of neuropsychological functioning in non-demented LLD patients.Methods; A comprehensive neuropsychological battery was administered to a group of hospitalized LLD patients and healthy control subjects. Thirty-nine patients without dementia, 60 years or older meeting DSM-IV criteria for current episode of major depression, and 18 nondepressed control subjects were included. The patient group was characterized by having a long lasting current depressive episode of late-onset depression and by being non-responders to treatment with antidepressants. Neurocognitive scores were calculated for the domains of information processing speed, verbal memory, visuospatial memory, executive function, and language. Number of impairments (performance below the 10th percentile of the control group per domain for each participant was calculated. Results: Nearly half of the patients had a clinically significant cognitive impairment in at least one neurocognitive domain. Relative to healthy control subjects, LLD patients performed significantly poorer in the domains of information processing speed and executive function. Executive abilities were most frequently impaired in the patient group (39 % of the patients. Even when controlling for differences in processing speed, patients showed more executive deficits than controls. CONCLUSIONS: Controlling for processing speed, patients still showed impaired executive function compared to healthy controls. Reduced executive function thus appears to be the core neurocognitive deficit in LLD. Executive function seems

  16. Human perceptual deficits as factors in computer interface test and evaluation

    Energy Technology Data Exchange (ETDEWEB)

    Bowser, S.E.


    Issues related to testing and evaluating human computer interfaces are usually based on the machine rather than on the human portion of the computer interface. Perceptual characteristics of the expected user are rarely investigated, and interface designers ignore known population perceptual limitations. For these reasons, environmental impacts on the equipment will more likely be defined than will user perceptual characteristics. The investigation of user population characteristics is most often directed toward intellectual abilities and anthropometry. This problem is compounded by the fact that some deficits capabilities tend to be found in higher-than-overall population distribution in some user groups. The test and evaluation community can address the issue from two primary aspects. First, assessing user characteristics should be extended to include tests of perceptual capability. Secondly, interface designs should use multimode information coding.

  17. Work-related stress is associated with impaired neuropsychological test performance: a clinical cross-sectional study. (United States)

    Eskildsen, Anita; Andersen, Lars Peter; Pedersen, Anders Degn; Vandborg, Sanne Kjær; Andersen, Johan Hviid


    Patients on sick leave due to work-related stress often complain about impaired concentration and memory. However, it is undetermined how widespread these impairments are, and which cognitive domains are most long-term stress sensitive. Previous studies show inconsistent results and are difficult to synthesize. The primary aim of this study was to examine whether patients with work-related stress complaints have cognitive impairments compared to a matched control group without stress. Our secondary aim was to examine whether the level of self-reported perceived stress is associated with neuropsychological test performance. We used a broad neuropsychological test battery to assess 59 outpatients with work-related stress complaints (without major depression) and 59 healthy controls. We matched the patients and controls pairwise by sex, age and educational level. Compared to controls, patients generally showed mildly reduced performance across all the measured domains of the neuropsychological test battery. However, only three comparisons reached statistical significance (p working memory. There were no statistical significant associations between self-reported perceived stress level and neuropsychological test performance. In conclusion, we recommend that cognitive functions should be considered when evaluating patients with work-related stress complaints, especially when given advice regarding return to work. Since this study had a cross-sectional design, it is still uncertain whether the impairments are permanent. Further study is required to establish causal links between work-related stress and cognitive deficits.

  18. Neuropsychological functioning in methadone maintenance patients with HIV

    Directory of Open Access Journals (Sweden)

    Enrique Vázquez-Justo


    Full Text Available Although highly active antiretroviral therapy (HAART has improved survival rates of HIV patients, HIV-associated neurocognitive disorders (HAND still exist in a highly prevalent group of persons with this disease. In this study we seek to evaluate the influence of drug use in the neuropsychological performance of seropositive drug users. We carried out an extensive neuropsychological evaluation and compared the performance of seropositive drug users (n = 90 with that of a control group of seronegative drug users (n = 48. The results reveal that methadone maintenance programmes can make the seropositive subject neuropsychologically vulnerable. Likewise, we found that giving up drugs have a protective effect in the presence of neuropsychological alterations associated with HIV. These findings lead us to suggest that seropositivity is not sufficient to explain the neuropsychological alterations of seropositive drug users, noting that these alterations are multifactorial.

  19. Attention deficit/hyperactivity disorder children with a 7-repeat allele of the dopamine recepter D4 gene have extreme behavior but normal performance on critical neuropsychological tests of attention

  20. Subtyping children's reading disabilities using a comprehensive neuropsychological measure. (United States)

    Crews, Kimberly J; D'Amato, Rik Carl


    This study examined subtypes of children with reading disabilities using the NEPSY (series of Neuropsychological tests authored by Marit Korkman, Ursula Kirk and Sally Kemp). Multiple methods of cluster analysis were performed with 80 elementary school-age children identified as reading disabled. Students completed the NEPSY Language Domain and the NEPSY Memory and Learning Domain. Three clusters emerged which were interpreted as: (1) a No Language or Memory Deficit Subtype, (2) a Global Language and Memory Deficit Subtype, and (3) a Global Memory Deficit Subtype. This study suggested that memory-related processes, not exclusively phonologically related processes, might contribute to reading difficulties. This investigation supported the utility of a neuropsychological approach to subtyping children's reading disabilities.

  1. Clinical neuropsychology in South Korea. (United States)

    Kim, Myung-Sun; Chey, Jeanyung


    Clinical neuropsychology in South Korea, albeit its relatively short history, has advanced dramatically. We review a brief history and current status of clinical neuropsychology in South Korea. The history, the educational pathway, the training pathway, the certification process, and careers in clinical neuropsychology in South Korea are reviewed. We have reviewed the neuropsychological services, including assessment and treatment, research on neurological and psychiatric populations, and neuropsychology education and the requirements related to education, training, and board examinations of those providing neuropsychological services in South Korea. We also describe how the Korean Society for Neuropsychology Research, the first and only meeting for neuropsychologists in the country established in 1999, has played a major role in how clinical neuropsychology is practiced and developed as a professional field in South Korea. Clinical neuropsychology in South Korea has achieved major progress over just a quarter of a century, and its future is promising in light of the increasing demand for neuropsychological services and advances in neuroscience in the country. Challenges that the community of clinical neuropsychologists are currently facing in South Korea, including formalizing neuropsychological curriculum and training programs and developing advanced credentialing procedures, are discussed.

  2. A cohort pilot study on HIV-associated neuropsychological impairments in haemophilia patients

    Silvia eRiva


    Full Text Available Despite advances in the management of HIV infection with the introduction of combination antiretroviral therapy (cART, it is well known that HIV can directly infect the central nervous system (CNS and, as a result of such infection, neuropsychological impairments can be manifested. In this study we tried to determine whether seropositivity was associated with a poor neuropsychological performance in patients with hemophilia and HIV. Such a cohort of patients is very often underrepresented and understudied in the HIV literature. To amend such a gap, we carried out an extensive neuropsychological evaluation on these patients, and compared their performance with that of a group of seronegative hemophilia patients. The results revealed that HIV infection in HIV seropositive (HIV+ hemophilia patients was associated with deficits in attention, short-term memory, abstraction and visual recognition. Such results are still preliminary and explorative due to the small cohort of patients enrolled. However, the results do seem to have some important implications for day-to-day functioning, as the level of impairment detected may cause difficulties in completing common everyday tasks such as maintaining adherence to complex medication regimens, or maintaining social life activities. Continued research into the mechanisms related to HIV and neurocognitive dysfunction may provide targets for interventions that could have meaningful consequences in the real world for HIV hemophilia patients.

  3. Neuropsychological, psychiatric, and physical manifestations in 149 members from 18 fragile X families. (United States)

    Cianchetti, C; Sannio-Fancello, G; Fratta, A L; Manconi, F; Orano, A; Pischedda, M P; Pruna, D; Spinicci, G; Archidiacono, N; Filippi, G


    One hundred forty-nine subjects from 18 families with fragile X [fra(X)] syndrome were evaluated for their neuropsychological, psychiatric, and physical characteristics. The 36 fra(X) males had intelligence quotients ranging from less than 20 to 61, which prevented the delineation of a reliable neuropsychological profile. Behaviour fitted DSM-III-R and ADI diagnostic criteria of autism in only 2 subjects, both with very low intelligence level (IQ less than 20). Of 36 heterozygotes (HZ), 22 had an IQ between 20 and 80 and 14 between 81 and 99. The neuropsychological profile of the latter was compared with IQ-age-environment-matched 14 normal females and 14 normal males. Significantly poorer results in HZ were found on immediate digit memory and on Raven's progressive matrices (a visuo-spatial test of logical capabilities). The latter result, in conjunction with those results on the Bender visual-motor gestalt test and on some WAIS subtests, suggests a frequent deficit in spatial capabilities in such subjects. Such results tended to be confirmed by the profiles of the 22 HZ with IQ 20-80. No psychiatric abnormalities were found in HZ, except in one subject with IQ less than 20 which fitted DSM-III-R and ADI criteria for autism. Typical physical manifestations, especially cranio-facial, were more frequently present in the HZ group with lower IQ. Subnormal IQ was probably the most reliable abnormality for the detection of HZ in 49 females at 50% and 25% risk of heterozygosity.

  4. Neuropsychological Impairments and Age-Related Differences in Children and Adolescents with Fetal Alcohol Spectrum Disorders. (United States)

    Tamana, Sukhpreet; Pei, Jacqueline; Massey, Donald; Massey, Valerie; Rasmussen, Carmen


    BackgroundChildren and adolescents with Fetal Alcohol Spectrum Disorders (FASD) exhibit a range of physical, cognitive, behavioral, and/or learning deficits, as wells as poor executive functioning (EF). Children and adolescents with FASD often show greater impairments on complex neuropsychological tasks. However, little is known about age-related differences among children and adolescents with FASD.ObjectivesThe goals of this cross-sectional study were to explore the overall profile of neuropsychological impairments and extended previous reports on age-related differences among children and adolescents with FASD. MethodWe compared 117 children and adolescents diagnosed with an FASD (aged 5-17 years), clinically assessed on a broad range of tests covering 6 neurobehavioral domains. Data from a clinical database was used to generate profiles of neuropsychological impairments for clinically referred children and adolescents evaluated for FASD between 2001 and 2005. ResultsChildren and adolescents were impaired (relative to the norm) on a number of domains that include academic achievement, language, verbal memory, EF, visual-motor integration, and motor abilities. Older participants with FASD (relative to the norm) showed greater difficulty in areas involving EF or processing of complex information than younger participants. ConclusionsThese results suggest that for children and adolescents with FASD impairments in those areas important for independent functioning may become more pronounced with increasing age. However, further longitudinal research is needed to ascertain age changes over time.

  5. [Neuropsychological profiles associated with the children's oral language disorders]. (United States)

    Conde-Guzón, P A; Conde-Guzón, M J; Bartolomé-Albistegui, M T; Quirós-Expósito, P

    Oral language disorders constitute a group of syndromes with a high prevalence among the childhood population. They form a heterogeneous group that ranges from simple problems in articulating a phoneme (dyslalias) to severe disorders affecting communication, such as children's dysarthrias and aphasias. In this paper our objective is to review the neuropsychological profiles of children who manifest different oral language disorders. Due to the wide range of clinical pictures and causations covered by children's oral language disorders, very few systematic reviews have been conducted to obtain an overall view of the neuropsychological profiles of these children. Although the linguistic signs and symptoms of these disorders are well understood, the associated neuropsychological signs and symptoms have not been studied. In some cases, these neuropsychological signs cause greater learning problems in children than the actual language problems themselves. Childhood language disorders are associated with different neuropsychological problems. The most commonly associated neuropsychological deficits are problems involving memory, attention, executive functions, motor dysfunctions, temporal perception, tactile recognition, body scheme, spatial orientation and difficulties in visual discrimination. Mnemonic disorders (essentially in short-term and working auditory memory) are usually a common denominator in the different clinical pictures that make up language disorders. The mnemonic impairment associated to dyslalias deserves special attention as this disorder is sometimes similar to that seen in language problems deriving from clinical pictures with important neurological alterations.

  6. Simulated Driving Skills Evaluation of Teenagers With Attention Deficit Hyperactivity Disorder Before Driving Lessons. (United States)

    Ratzon, Navah Zelda; Lunievsky, Efrat Kadury; Ashkenasi, Arie; Laks, Joseph; Cohen, Herman Avner

    We evaluated the driving skills of teenagers with attention deficit hyperactivity disorder (ADHD) during simulated driving before starting driving lessons and observed whether methylphenidate (MPH) affected their performance. Sixty teenagers ages 15-18 yr were included; 29 teenagers with ADHD were tested with and without MPH, and 31 teenagers (control group) were tested once. All participants were tested on the STISIM Drive™ simulator. The number of center-line crossings was higher in the group without MPH treatment than in the control group and the MPH-treated group. The group without MPH treatment had more road-edge excursions compared with the control group and drove faster than the MPH-treated group. Adolescents with ADHD without MPH treatment demonstrated impaired performance more often while driving the simulator, resembling characteristics found during on-road driving among teenagers with ADHD. Trainer awareness is a primary intervention before taking driving lessons to help teenagers achieve safe driving performance.

  7. The use of event-related potential (P300) and neuropsychological testing to evaluate cognitive impairment in mild traumatic brain injury patients. (United States)

    Nandrajog, Puneet; Idris, Zamzuri; Azlen, Wan Nor; Liyana, Alwani; Abdullah, Jafri Malin


    The aim of the study is to compare the amplitude and latency of the P300 event-related potential (ERP) component between a control group and patients after mild traumatic brain injury (mTBI) during 1-7 days (short duration) and 2-3 months (long duration), and to compare the outcome of neuropsychological tests between the long duration postinjury and control study groups. We studied responses to auditory stimulation in two main and one subgroups, namely the control healthy group (19 patients, both ERP and neuropsychology test done), the mTBI 1 group (17 patients, only ERP done within 7 days after injury), and the mTBI 2 subgroup (the 17 mTBI 1 patients in whom a repeated ERP together with neuropsychological testing was done at 2-3 months postinjury). Auditory evoked responses were studied with two different stimuli (standard and target stimuli), where the P300 amplitude and latency were recorded from three midline sites and results were compared between the groups, as were the neuropsychological test results. There was a significant prolongation of the target P300 latency values shown by the MBI 1 group measured at the central electrode when compared to the control group, which was also seen when the mTBI 1 and mTBI 2 groups were compared. The results of the P300 amplitude values measured at the frontal electrode showed the control group to have higher readings during the presentation of standard tones when compared to the mTBI 1 group. The mTBI 2 group performed better on some neuropsychological tests. The latency of P300 was significantly prolonged in early mTBI patients who improved over time, and the neuropsychological testing on mTBI 2 patients showed them to be comparable to the control group. The study indicates that ERP should be used as an additional modality of investigation in mTBI patients.

  9. Neuropsychological functioning in Wernicke′s encephalopathy

    Directory of Open Access Journals (Sweden)

    Sushree Sangita Behura


    Full Text Available Context: Wernicke′s encephalopathy (WE is caused by thiamine (Vitamin B1 deficiency and most commonly found in chronic alcoholism and malnutrition. Clinically, the key features are mental status disturbances (global confusion, oculomotor abnormalities, and gait disturbances (ataxia. Apart from these clinical features, we can find deficits in neuropsychological functioning in patients with WE, which is more prominent after the improvement in the physical conditions. Neuropsychological functioning includes both basic cognitive processes (i.e., attention-concentration as well as higher order cognitive processes (i.e., memory, executive functioning, reasoning, which is much vital for the maintenance of quality of life of an individual. However, unfortunately, in most of the cases, neuropsychological functioning is ignored by the clinicians. Materials and Methods: In this study four case reports of WE have been presented. The patients were taken from the outdoor department of Mental Health Institute, S.C.B. Medical College, Cuttack, Odisha. Neuropsychological functioning was measured by administration of PGIBBD and Quality of Life was measured by WHO-QOL BREF Odia Version. Discussion: As described in the literature, among the three cardinal signs ( global confusion, ataxia, and ocular sings, the first two were present in all cases, but nystagmus was present in only two cases.Memory dysfunction was so disabling that the persons were unable to maintain a good Quality of Life and occupational impairment was prominent. There are disturbances in recent, remote memory, immediate recall, delayed recall, and attention and concentration, ultimately creating both physical and mental disability. PGI-BBD findings also suggest the overall impairment in neuropsychological functioning other than memory, that is, executive functioning, visual acuity, and depth perception. Findings of WHO-QOL BREF suggest the impairment of four domains of QOL in all the cases, but

    Friedreich ataxia, an autosomal recessive mitochondrial disease, is the most frequent inherited ataxia. Many studies have attempted to identify cognitive and affective changes associated with the disease, but conflicting results have been obtained, depending on the tests used and because many of the samples studied were very small. We investigated personality and neuropsychological characteristics in a cohort of 47 patients with genetically confirmed disease. The neuropsychological battery assessed multiple cognition domains: processing speed, attention, working memory, executive functions, verbal memory, vocabulary, visual reasoning, emotional recognition, and social cognition. Personality was assessed with the Temperament and Character Inventory, and depressive symptoms were assessed with the Beck Depression Inventory. We found deficits of sustained attention, processing speed, semantic capacities, and verbal fluency only partly attributable to motor deficit or depressed mood. Visual reasoning, memory, and learning were preserved. Emotional processes and social cognition were unimpaired. We also detected a change in automatic processes, such as reading. Personality traits were characterized by high persistence and low self-transcendence. The mild cognitive impairment observed may be a developmental rather than degenerative problem, due to early cerebellum dysfunction, with the impairment of cognitive and emotional processing. Disease manifestations at crucial times for personality development may also have an important impact on personality traits.

  11. The Development and Psychometric Evaluation of a Supplementary Index Score of the Neuropsychological Assessment Battery Screening Module that is Sensitive to Traumatic Brain Injury. (United States)

    Hacker, David; Jones, Christopher A; Clowes, Zoe; Belli, Antonio; Su, Zhangjie; Sitaraman, Murugan; Davies, David; Taylor, Ross; Flahive, Elizabeth; Travis, Clare; O'Neil, Nicci; Pettigrew, Yvonne


    This study examines the validity of the NAB Screening Module (screening module of the neuropsychological assessment battery, S-NAB) in an acute traumatic brain injury (TBI) inpatient population and provides psychometric evaluation of an original index sensitive to TBI impairment. The utility of the S-NAB as a TBI screen was examined using a between groups design. One-hundred and four patients with mild complicated to severe TBI were recruited from a consecutive cohort of patients admitted as inpatients to a UK Major Trauma Centre. Ninety-eight control participants were selected from the S-NAB normative sample. All TBI patients completed the S-NAB during their inpatient stay. Control participants scored significantly higher than TBI participants on the Total Screening index (t = 3.626, p < 0.01), The Attention index (t = 7.882, p < 0.01), and the Executive index (t = 5.577, p < 0.01). A briefer TBI Impairment index of six subtests was constructed which accurately discriminated TBI patients from normative controls (t = 9.9, p < 0.01; Cohen's d = 1.54). The TBI index had excellent classification accuracy (AUC = 0.83), superior to that of the standard S-NAB indices. The TBI Index, Attention Index, and Total Screening Index demonstrated increasing impairment with increased severity of injury. The S-NAB TBI index is a robust, reliable screening index for use with acute TBI patients, which is sensitive to the effects of acute TBI. It affords a briefer cognitive screen than the S-NAB and demonstrates a dose response relationship to TBI severity.

  14. The relationship between neuropsychological assessment, numeracy, and functional status in older adults with type 1 diabetes. (United States)

    Chaytor, Naomi S; Riddlesworth, Tonya D; Bzdick, Suzan; Odegard, Peggy S; Gray, Shelly L; Lock, John-Paul; DuBose, Stephanie N; Beck, Roy W


    While data are accumulating on the association between neuropsychological performance and real-world endpoints, less is known about the association with medical self-management skills. The self-management of type 1 diabetes (T1D) is often complex, and mismanagement can result in hypoglycaemia and hyperglycaemia and associated morbidity and mortality. The T1D Exchange conducted a case-control study evaluating factors associated with severe hypoglycaemia in older adults (≥ 60 years old) with longstanding T1D (≥ 20 years). A battery of neuropsychological and functional assessments was administered, including measures of diabetes-specific self-management skill (diabetes numeracy) and instrumental activities of daily living (IADL). After adjusting for confounding variables, diabetes numeracy was related to memory and complex speeded attention; while IADL were associated with simple processing speed, executive functioning, complex speeded attention and dominant hand dexterity. The severity of overall cognitive deficit was uniquely associated with both diabetes numeracy and IADL, when controlling for age, education, frailty and depression. This study demonstrates that the cognitive deficits in older adults with T1D have functional implications for both diabetes management and IADL. Further research is needed to determine specific interventions to maximise diabetes self-management in older adults with declining cognition.

    Full Text Available Theresa Coles,1 Cheryl Coon,1 Carla DeMuro,1 Lori McLeod,1 Ari Gnanasakthy21Patient-Reported Outcomes, RTI Health Solutions, Research Triangle Park, NC, 2Novartis Pharmaceuticals, East Hanover, NJ, USAAbstract: Inattention and impulsivity symptoms are common among adults with attention-deficit/hyperactivity disorder (ADHD, which can lead to difficulty concentrating, restlessness, difficulty completing tasks, disorganization, impatience, and impulsiveness. Many adults with ADHD find it difficult to focus and prioritize. Resulting outcomes, such as missed deadlines and forgotten engagements, may ultimately impact the ability to function at work, school, home, or in a social environment. The European Medicines Agency guidelines for evaluating medicinal products for ADHD recommend inclusion of both functional outcomes, such as school, social, or work functioning, and outcomes related to symptoms of ADHD in clinical studies of novel medication primary efficacy endpoints. Due to its performance in other disease areas and the relevance of its items as evidenced by content validity analyses, the Sheehan Disability Scale (SDS was chosen to assess functional impairment in ADHD. The aim of this study was to investigate the psychometric properties of the SDS, used as a brief measure of functional impairment in a number of psychiatric disorders, in adult patients with ADHD. To the authors' knowledge, this is the first study to evaluate the reliability of the SDS (based on Cronbach's coefficient alpha and test-retest reliability, its validity (construct and known-groups validity, and its ability to detect change in this patient population. This study also established a preliminary responder definition for the SDS in this study population to determine when change can be considered clinically beneficial in a clinical trial setting. The psychometric results support the use of the SDS subscales (items 1–3 and total score (sum of items 1–3 in an ADHD

  1. Vygotsky in applied neuropsychology

    Directory of Open Access Journals (Sweden)

    Glozman J. M.


    Full Text Available The aims of this paper are: 1 to show the role of clinical experience for the theoretical contributions of L.S. Vygotsky, and 2 to analyze the development of these theories in contemporary applied neuropsychology. An analysis of disturbances of mental functioning is impossible without a systemic approach to the evidence observed. Therefore, medical psychology is fundamental for forming a systemic approach to psychology. The assessment of neurological patients at the neurological hospital of Moscow University permitted L.S. Vygotsky to create, in collaboration with A.R. Luria, the theory of systemic dynamic localization of higher mental functions and their relationship to cultural conditions. In his studies of patients with Parkinson’s disease, Vygotsky also set out 3 steps of systemic development: interpsychological, then extrapsychological, then intrapsychological. L.S. Vygotsky and A.R. Luria in the late 1920s created a program to compensate for the motor subcortical disturbances in Parkinson’s disease (PD through a cortical (visual mediation of movements. We propose to distinguish the objective mediating factors — like teaching techniques and modalities — from subjective mediating factors, like the individual’s internal representation of his/her own disease. The cultural-historical approach in contemporary neuropsychology forces neuropsychologists to re-analyze and re-interpret the classic neuropsychological syndromes; to develop new assessment procedures more in accordance with the patient’s conditions of life; and to reconsider the concept of the social brain as a social and cultural determinant and regulator of brain functioning. L.S. Vygotsky and A.R. Luria proved that a defect interferes with a child’s appropriation of his/her culture, but cultural means can help the child overcome the defect. In this way, the cultural-historical approach became, and still is, a methodological basis for remedial education.

    Subcortical dementias are a heterogeneous group of disorders that share primary pathology in subcortical structure and a characteristic pattern of neuropsychological impairment. This article describes the neurobiological and cognitive features of three prototypical subcortical dementias, Parkinson's disease, Huntington's disease, and progressive supranuclear palsy, concentrating of traits shared by disorders. Clinical features are also discussed, especially those which differentiate subcortical dementias from cortical dementias, such as Alzheimer's disease. The cortical-subcortical nomenclature has been criticized over the years, but it continues to provide an effective means of classifying dementia profiles in clinically and theoretically useful ways.

  3. The neuropsychology of hallucinations

    Directory of Open Access Journals (Sweden)

    Pavlović D.M.


    Full Text Available Hallucinations are a psychopathological phenomenon with neuropsychological, neuroanatomical and pathophysiological correlates in specific brain areas. They can affect any of the senses, but auditory and visual hallucinations predominate. Verbal hallucinations reveal no gross organic lesions while visual hallucinations are connected to defined brain lesions. Functional neuroimaging shows impairments in modality specific sensory systems with the hyperactivity of the surrounding cerebral cortex. Disinhibition and expansion of the inner speech was noted with impaired internal monitoring in auditory verbal hallucinations. The subcortical areas and modal-specific associative cortex and cingulate cortex are essential for the occurrence of hallucinations.

  4. Assessment of stigma associated with attention deficit hyperactivity disorder: Psychometric evaluation of the ADHD Stigma Questionnaire (United States)

    Kellison, Ida; Bussing, Regina; Bell, Lindsay; Garvan, Cynthia


    This study evaluated the psychometric properties of the ADHD Stigma Questionnaire (ASQ) among a community sample of 301 adolescents ages 11–19 years at high (n = 192) and low risk (n = 109) for attention deficit hyperactivity disorder (ADHD). Study subjects were drawn from a cohort study assessing ADHD detection and service use. The 26-item ASQ demonstrated good internal consistency. Confirmatory factor analysis using random parceling supported a three factor structure with highly correlated subscales of Disclosure Concerns, Negative Self Image, and Concern with Public Attitudes, and a Schmid-Leiman analysis supported an overall stigma factor. Test-retest stability was assessed after two-weeks (n = 45) and found to be adequate for all three subscales. Construct validity was supported by relationships with related constructs, including clinical maladjustment, depression, self-esteem and emotional symptoms and the absence of a relationship with school maladjustment. Findings indicate that the ASQ has acceptable psychometric properties in a large community sample of adolescents, some of whom met DSM-IV criteria for ADHD. PMID:20580842

  5. [Neuropsychology of dreams]. (United States)

    Tirapu-Ustarroz, J


    Dreams are a universal human experience and studying them from the point of view of neuroscience, consciousness, emotions and cognition is quite a challenge for researchers. Thus, dreams have been addressed from a number of different perspectives ranging from philosophy to clinical medicine, as well as psychiatry, psychology, artificial intelligence, neural network models, psychophysiology or neurobiology. The main models are grounded on the biological function of dreams, especially those based on processes involving the consolidation of memory and forgetting, and models of simulation. Similarly, current models are developed upon the neurobiology and the neuropsychology of the REM phases of sleep and how they are differentiated from wakefulness. Thus, neurobiologically speaking, dreams are related to the role of acetylcholine and, neuropsychologically, to the activation of the limbic and paralimbic regions, the activation of the basal ganglia, the activation of cortical areas with a specific modality (especially Brodmann's areas 19, 22 and 37) and the deactivation of the ventromedial, parietal and dorsolateral prefrontal cortex and posterior cingulate. Dreams can be considered a state of consciousness that is characterised by a reduced control over their content, visual images and activation of the memory, and which is mediated by motivational incentives and emotional salience.

  6. Neuropsychology of music – a rapidly growing branch of psychology

    Directory of Open Access Journals (Sweden)

    Katarina Habe


    Full Text Available Relationship between brain and music is of interest to musicians, psychologists and neuroscientists. In recent years no other area of psychology of music has seen as much advancement as neuropsychology of music. The aim of the article is to present some main issues in the neuropsychology of music abroad and in Slovenia, to classify research studies into larger categories and to predict the future development of this field.There are different levels of inquiry into the neuropsychology of music: (1 the analysis of normal and abnormal psychological and physiological functions to determine the principles and modes by which the human brain processes, codifies, stores, and produces music, and (2 a description of the clinical deficits in music perception or performance resulting from localized or diffuse damage to the nervous system. Main topics that occupy neuropsychology of music are neuropsychological models of musical processing, functional imaging of musical perception and cognition, and the use of music as a therapeutic and clinical tool. Although some important studies have already been conducted since the year 2003, in Slovenia we faced a "formal" turning point in acknowledging the importance of the connection between music, mind and brain with the Sinapsa's Week of the brain 2009 under the title Brain and music.

  9. Characterisation and evaluation of UK websites on attention deficit hyperactivity disorder. (United States)

    Akram, G; Thomson, A H; Boyter, A C; Morton, M J S


    To identify, characterise and evaluate UK websites providing information about attention deficit hyperactivity disorder (ADHD) and its pharmacological management. Cross-sectional survey of websites identified by entering "ADHD" into five search engines. 48 websites. Each website was scored against 26 criteria using a bespoke instrument to evaluate (a) quality of information on the disorder and its drug treatment and (b) physical characteristics of the site. Most sites (n = 22) were hosted by charities and support groups, 12 were by commercial organisations, nine were from government or professional bodies, and five were categorised as miscellaneous. Mean total scores per host category ranged from 18.8 to 21 out of 46, with mean (SD) scores of 5.5 (4.2) out of 28 for content and 14.8 (3.0) out of 18 for physical properties. The government/professional sites scored highest for both content and physical properties. Descriptions of the disorder and its drug treatment were poor and lacking in detail. Although most sites mentioned stimulants, only eight discussed atomoxetine and described how both types of drug worked. Ten sites provided detailed information about side effects. The role of different stimulant brands and formulations was discussed on six sites. Authorship details were generally vague. Physical properties related to navigation and layout performed well. Only four sites used language deemed suitable for consumer-orientated health information. Information on UK websites about drug treatment for ADHD is basic and incomplete. Websites by government and professional bodies perform better than those in other categories.

  10. Neuropsychological correlates of emotional lability in children with ADHD


    Banaschewski, Tobias; Jennen-Steinmetz, Christine; Brandeis, Daniel; Buitelaar, Jan K.; Kuntsi, Jonna; Poustka, Luise; Sergeant, Joseph A.; Sonuga-Barke, Edmund J.; Frazier-Wood, Alexis C.; Albrecht, Björn; Chen, Wai; Uebel, Henrik; Schlotz, Wolff; van der Meere, Jaap J.; Gill, Michael


    Background: Emotional lability (EL) is commonly seen in patients with attention-deficit/hyperactivity disorder (ADHD). The reasons for this association remain currently unknown. To address this question, we examined the relationship between ADHD and EL symptoms, and performance on a range of neuropsychological tasks to clarify whether EL symptoms are predicted by particular cognitive and/or motivational dysfunctions and whether these associations are mediated by the presence of ADHD symptoms....

  11. Identification of attention-deficit-hyperactivity disorder and conduct disorder in Mexican children by the scale for evaluation of deficit of attention and hyperactivity. (United States)

    Zambrano-Sánchez, Elizabeth; Martínez-Cortés, José A; Del Rió-Carlos, Yolanda; Martínez-Wbaldo, Ma Del Consuelo; Poblano, Adrián


    The objective was weighing the usefulness of a Spanish-language Scale for the evaluation of deficit of attention and hyperactivity (EDAH) to identify children with attention deficit-hyperactivity disorder (AD-HD) and conduct disorder (CD) in a sample of school-aged children. We studied 132 children from a government-run public elementary school previously selected by teachers as having learning and attention disorders. We screened children of the sample with parents' and teachers' EDAH and Diagnostic and Statistical Manual of Mental Disorders-IV edition Text Revision (DSM-IV-TR) questionnaires, and performed an interdisciplinary clinical examination for the final diagnosis. We found 81 children with AD-HD and 51 children without AD-HD. AD-HD was classified as follows: AD-HD-combined (-C), n=32; AD-HD-inattentive (-I), n=17 and AD-HD-hyperactive (-H), n=32. Cronbach's alpha calculation for the EDAH parents' questionnaire was 0.76, and for teachers, 0.80. Sensitivity of the teachers' EDAH questionnaire was 0.94, and specificity, 0.91. Sensitivity of the parents' EDAH questionnaire was 0.91, while specificity was 0.87. The data of EDAH parents' and teachers' questionnaires have a concordance of 93.1% and 80%, respectively. The correlation of scores among parents' and teachers' EDAH scales was significant. The correlation between results from parents' and teachers' DSM-IV-TR and EDAH questionnaires was also significant. Our results partially support the use of EDAH questionnaires for AD-HD and CD screening in Spanish-speaking populations. Published by Elsevier Ireland Ltd.

  12. Neuropsychological function and memory suppression in conversion disorder. (United States)

    Brown, Laura B; Nicholson, Timothy R; Aybek, Selma; Kanaan, Richard A; David, Anthony S


    Conversion disorder (CD) is a condition where neurological symptoms, such as weakness or sensory disturbance, are unexplained by neurological disease and are presumed to be of psychological origin. Contemporary theories of the disorder generally propose dysfunctional frontal control of the motor or sensory systems. Classical (Freudian) psychodynamic theory holds that the memory of stressful life events is repressed. Little is known about the frontal (executive) function of these patients, or indeed their general neuropsychological profile, and psychodynamic theories have been largely untested. This study aimed to investigate neuropsychological functioning in patients with CD, focusing on executive and memory function. A directed forgetting task (DFT) using words with variable emotional valence was also used to investigate memory suppression. 21 patients and 36 healthy controls completed a battery of neuropsychological tests and patients had deficits in executive function and auditory-verbal (but not autobiographical) memory. The executive deficits were largely driven by differences in IQ, anxiety and mood between the groups. A subgroup of 11 patients and 28 controls completed the DFT and whilst patients recalled fewer words overall than controls, there were no significant effects of directed forgetting or valence. This study provides some limited support for deficits in executive, and to a lesser degree, memory function in patients with CD, but did not find evidence of altered memory suppression to support the psychodynamic theory of repression. © 2013 The British Psychological Society.

Results: Recent memory in the DLB group was significantly better than tha...

  14. How neuropsychology can inform our understanding of preschool ADHD: Clinical and research implications. (United States)

    Aretouli, Eleni


    Neuropsychological assessments in preschoolers have not received as much attention as in older children and adults. Attention-deficit/hyperactivity disorder (ADHD) is a common disorder that occurs in early childhood associated with poor academic and personal outcomes, such as learning and social difficulties. Preschoolers with ADHD may present cognitive deficits that are related with the ADHD symptoms of inattention, hyperactivity, and impulsivity, but may also interfere, beyond and above the ADHD symptoms, with everyday functioning. Most importantly, cognitive deficits in preschoolers seem to predict future ADHD symptoms. Yet, the practice of neuropsychological assessment in this age-group has been limited. The present selective review highlights the contribution of comprehensive neuropsychological assessments to the early identification of symptomatic preschoolers and to our understanding of the nature and developmental trajectory of ADHD.

  15. Descartes' pineal neuropsychology. (United States)

    Smith, C U


    The year 1996 marked the quattrocentenary of Descartes' birth. This paper reviews his pineal neuropsychology. It demonstrates that Descartes understood the true anatomical position of the pineal. His intraventricular pineal (or glande H) was a theoretical construct which allowed him to describe the operations of his man-like "earthen machine." In the Treatise of Man he shows how all the behaviors of such machines could then be accounted for without the presence of self-consciousness. Infrahuman animals are "conscious automata." In Passions of the Soul he adds, but only for humans, self-consciousness to the machine. In a modern formulation, only humans not only know but know that they know. Copyright 1998 Academic Press.

  16. Overweight in Boys With ADHD Is Related to Candidate Genes and Not to Deficits in Cognitive Functions. (United States)

    Hanć, Tomasz; Dmitrzak-Węglarz, Monika; Borkowska, Aneta; Wolańczyk, Tomasz; Pytlińska, Natalia; Rybakowski, Filip; Słopień, Radosław; Słopień, Agnieszka


    The aim of the study was to assess the relationship of overweight, the polymorphisms of selected candidate genes, and deficits in the executive functions among children with ADHD. We examined 109 boys with ADHD aged between 7 and 17 years. The study indicated variants of 14 polymorphisms in eight candidate genes. We applied seven neuropsychological tests to evaluate the executive functions. Overweight was diagnosed on the basis of the guidelines of the International Obesity Task Force. Analyses revealed significant association between DRD4 rs1800955, SNAP25 rs363039 and rs363043, 5HTR2A rs17288723, and overweight in boys with ADHD. There were no significant differences in the level of neuropsychological test results between patients with overweight and without overweight. Overweight in boys with ADHD is associated with polymorphisms in three candidate genes: DRD4, SNAP25, and 5HTR2A, but not through conditioning deficits in cognitive functions. © The Author(s) 2016.

  17. Neuropsychology of Aesthetic Judgment of Ambiguous and Non-Ambiguous Artworks

    Directory of Open Access Journals (Sweden)

    Maddalena Boccia


    Full Text Available Several affective and cognitive processes have been found to be pivotal in affecting aesthetic experience of artworks and both neuropsychological as well as psychiatric symptoms have been found to affect artistic production. However, there is a paucity of studies directly investigating effects of brain lesions on aesthetic judgment. Here, we assessed the effects of unilateral brain damage on aesthetic judgment of artworks showing part/whole ambiguity. We asked 19 unilaterally brain-damaged patients (10 left and 9 right brain damaged patients, respectively LBDP and RBDP and 20 age- and education-matched healthy individuals (controls, C to rate 10 Arcimboldo’s ambiguous portraits (AP, 10 realistic Renaissance portraits (RP, 10 still life paintings (SL, and 10 Arcimboldo’s modified portraits where only objects/parts are detectable (AO. They were also administered a Navon task, a facial recognition test, and evaluated on visuo-perceptual and visuo-constructional abilities. Patients included in the study did not show any deficits that could affect the capability to explore and enjoy artworks. SL and RP was not affected by brain damage regardless of its laterality. On the other hand, we found that RBDP liked AP more than the C participants. Furthermore, we found a positive correlation between aesthetic judgment of AP and visuo-perceptual skills even if the single case analyses failed to find a systematic association between neuropsychological deficits and aesthetic judgment of AP. On the whole, the present data suggest that a right hemisphere lesion may affect aesthetic judgment of ambiguous artworks, even in the absence of exploration or constructional deficits.

  18. Evaluation of Selected Soybean Genotypes (GLYCINE MAX L. by Physiological Responses during Water Deficit

    Directory of Open Access Journals (Sweden)

    Eleonora KRIVOSUDSKA


    Full Text Available During the experiments were monitored the following varieties: Impala (South African Republic, Maverick (USA, Rankoshi No.1h (Japan and their reactions to the water supply at the beginning of the growth stage R1 and R2 blooming in an interaction with the Nitrazon inoculation of the seeds before a sowing. Mentioned genetic resources were provided for our research purposes by the Plant Production Research Center PRRC Piesany, Gene Bank of the Slovak Republic. Seeding of the particular soy genotypes was made into the containers whilst 50% of seed corn from each genotype was before the sowing inoculated by the usage of Nitrazon inoculant (supplier: Agrokomp, spol. s.r.o., Modra. Water stress was secured by an irrigation interruption for a 7-day period in the mentioned growth stage. This stress had a negative impact on the relative water content in RWC plants, proline content, osmotic potential, SPAD, stress index as well as an amount of nodules on the roots by the all monitored varieties. According to an evaluation of the mentioned indicators more significant proline accumulation was confirmed by the genotype Maverick especially by the variant exposed to water deficit 3,25 micro mol g 1 FW according to the calculations on 100 percent RWC without the inoculant Nitrazon use and inoculating variant 2.99 micro mol g 1 FW according to calculations on 100 percent RWC. Variety MAVERICK had got the best reaction to water stress and even more noticeable resistance to the stress was monitored in the variant with Nitrazon application in the foregoing seed treatment of soybean seeds. The opposite response to the inoculation was monitored by IMPALA genotype when RWC had dropped to 41.77% in the comparison with the variant without inoculation where RWC had dropped to 61.86%.

  19. Evaluating the Sustainability of the Current Account Deficits of Ukraine: the Modern Trends

    Directory of Open Access Journals (Sweden)

    Bazhenova Olena V.


    Full Text Available The article analyzes the dynamics of the current account of the balance of payments of Ukraine, which indicates the persistence of its imbalances. The accumulated current account deficits preceded economic crises, confirming the hypothesis that the countries that demonstrate sustained current account deficits on the eve of crises suffer significant losses as a result of their occurrence. The main tendencies in Ukraine in the context of imbalances in investment and savings were analyzed. It has been shown that GDP growth was not accompanied by an increase in the current account deficits, which also signals its volatility. The current account deficit is attributable mainly to the negative net export balance that shows a decline in the foreign exchange earnings to resettle and service the previously accumulated external debt, which became especially actual in the last three years. The calculation of balance of the current account of Ukraine on the basis of its components and in accordance with the financial and capital accounts data has revealed a significant volume of hidden exports. Moreover, in recent years, the deterioration of situation in the context of external sustainability is determined by a combination of current account deficits and a rapid increase in the debt burden on the economy.

  20. Neuropsychological Assessment: Past and Future. (United States)

    Casaletto, Kaitlin B; Heaton, Robert K


    Neuropsychological assessment tools are the staple of our field. The development of standardized metrics sensitive to brain-behavior relationships has shaped the neuropsychological questions we can ask, our understanding of discrete brain functions, and has informed the detection and treatment of neurological disorders. We identify key turning points and innovations in neuropsychological assessment over the past 40-50 years that highlight how the tools used in common practice today came to be. Also selected for emphasis are several exciting lines of research and novel approaches that are underway to further probe and characterize brain functions to enhance diagnostic and treatment outcomes. We provide a brief historical review of different clinical neuropsychological assessment approaches (Lurian, Flexible and Fixed Batteries, Boston Process Approach) and critical developments that have influenced their interpretation (normative standards, cultural considerations, longitudinal change, common metric batteries, and translational assessment constructs). Lastly, we discuss growing trends in assessment including technological advances, efforts to integrate neuropsychology across disciplines (e.g., primary care), and changes in neuropsychological assessment infrastructure. Neuropsychological assessment has undergone massive growth in the past several decades. Nonetheless, there remain many unanswered questions and future challenges to better support measurement tools and translate assessment findings into meaningful recommendations and treatments. As technology and our understanding of brain function advance, efforts to support infrastructure for both traditional and novel assessment approaches and integration of complementary brain assessment tools from other disciplines will be integral to inform brain health treatments and promote the growth of our field.

  1. Understanding cognitive dysfunction in multiple sclerosis: integrating a first-person perspective with neuropsychological testing, neuroimaging, and cognitive neuroscience research. (United States)

    Courtney, Susan M


    This paper gives perspectives on a companion article, the case history of a professional writer who has multiple sclerosis. The patient's first-person account of her illness is combined with clinical summaries about her care. The discussion of this case illustrates the value of combining such subjective and objective reports in evaluating a patient. Furthermore, considering these reports in the context of current research findings on the organization and function of cognitive neural systems can shed light on patients' seemingly contradictory clinical findings. For this patient, a deficit in the ability to select the most important information to achieve her current goals reflected her neuropsychological test results and neuroradiologic findings, and helped to explain her difficulties with her job and her activities of daily living. Because the patient's cognitive impairments have been her primary manifestations of multiple sclerosis, she illustrates the importance of physicians attending to and helping patients manage their cognitive deficits.

  2. Neuropsychological correlates of sustained attention in schizophrenia. (United States)

    Chen, E Y; Lam, L C; Chen, R Y; Nguyen, D G; Chan, C K; Wilkins, A J


    We employed a simple and relatively undemanding task of monotone counting for the assessment of sustained attention in schizophrenic patients. The monotone counting task has been validated neuropsychologically and is particularly sensitive to right prefrontal lesions. We compared the performance of schizophrenic patients with age- and education-matched controls. We then explored the extent to which a range of commonly employed neuropsychological tasks in schizophrenia research are related to attentional impairment as measured in this way. Monotone counting performance was found to be correlated with digit span (WAIS-R-HK), information (WAIS-R-HK), comprehension (WAIS-R-HK), logical memory (immediate recall) (Weschler Memory Scale, WMS), and visual reproduction (WMS). Multiple regression analysis also identified visual reproduction, digit span and comprehension as significant predictors of attention performance. In contrast, logical memory (delay recall) (WMS), similarity (WAIS-R-HK), semantic fluency, and Wisconsin Card Sorting Test (perseverative errors) were not correlated with attention. In addition, no significant correlation between sustained attention and symptoms was found. These findings are discussed in the context of a weakly modular cognitive system where attentional impairment may contribute selectively to a range of other cognitive deficits.

  4. [Neuropsychological findings in a case of porencephaly]. (United States)

    Matarín, M M; Arasanz, C; Oms, B; Olivella, J; Junqué, C

    At the present time porencephalia refers to the presence of deep, unilateral or bilateral cavities or excavations, frequently communicating with the subarachnoid space or lateral ventricles, which occur following brain destruction during the end of the foetal or beginning of the new-born period. The clinical features are various forms of cerebral paralysis (spastic hemiparesia, diplegia and tetraplegia), mental retardation and epileptic crises. To date there are few studies giving detailed analysis of the cognitive functions of affected persons. We studied the mental and cognitive state of an adult woman with massive porencephalic dilatation of the left lateral ventricle. The patient had a normal verbal intelligence quotient. Cortical function, including language, praxis and gnosis were maintained. She had alterations of memory, particularly verbal, and of frontal function. The deficits observed were not lateralized for neocortical functions, but were lateralized for memory. The neuropsychological pattern partly corresponded to subcortical deterioration due to the lesions of the white matter and basal ganglio.

  5. Decline in changing Montreal Cognitive Assessment (MoCA scores is associated with post-stroke cognitive decline determined by a formal neuropsychological evaluation.

    Directory of Open Access Journals (Sweden)

    Hui Hui Tan

    Full Text Available We aimed to examine changes in the Montreal Cognitive Assessment (MoCA and Mini-Mental State Examination (MMSE scores within a one-year period after stroke/transient ischemic attack (TIA in associating cognitive decline determined by a formal neuropsychological test battery.Patients with ischemic stroke/TIA received MoCA and MMSE at baseline within 14 days after stroke/TIA, at 3-6 months and 1-year follow-ups. The scores of MoCA and MMSE were considered to have declined if there were a reduction of ≥2 points in the respective scores measured across two time points. The decline in neuropsychological diagnosis transitional status was defined by a category transition from no cognitive impairment or any cognitive impairment to a more severe cognitive impairment or dementia.275 patients with a mean age of 59.8 ± 11.6 years, and education of 7.7 ± 4.3 years completed all the assessments at baseline, 3-6 months and 1-year follow-ups. A decline in MoCA scores from 3-6 months to 1 year was associated with higher risk of decline in diagnosis transitional status (odd ratio = 3.21, p = 0.004 in the same time period whereas there was no association with a decline in MMSE scores.The decline in MoCA scores from 3-6 months to 1 year after stroke/TIA has three times higher risk for decline in the diagnosis transitional status. The decline of MoCA scores (reduction ≥ 2points is associated with the decline in neuropsychological diagnosis transitional status.

  6. Percived ethical misconduct: a survey of Neuropsychology professionals in Mexico

    Directory of Open Access Journals (Sweden)

    Paola Fonseca


    Full Text Available Objective: To evaluate the frequency of perceived ethical misconduct in the practice of neuropsychology in Mexico. Method: One hundred fourteen psychologists answered a survey which assessed perceptions of ethical misconduct in four areas of professional practice in the field of neuropsychology. Results: The area of professional training contained the highest percentage of perception of ethical misconduct, followed by research and publications, clinical care, and professional relationships. Conclusion: The high frequency of ethical misconduct perceived by neuropsychology professionals in Mexico is a cause for concern. The results suggest the need to create and implement a system to make sure that professionals follow the ethics standards required by the profession, and to provide consequences for those who fail to do so. The profession of neuropsychology and training of professionals in the field must be regularized in the country, to reduce the frequency of future ethical misconducts.

  8. The neuropsychological function of children with achondroplasia. (United States)

    Wigg, Kimberley; Tofts, Louise; Benson, Suzanne; Porter, Melanie


    The current observational study had three specific objectives: (i) to document any neuropsychological impairment in a sample of children with achondroplasia; (ii) to explore individual variability; and (iii) to determine the functional impact of any impairments. Fourteen children aged between 6 and 15 years with a medically confirmed diagnosis of achondroplasia (FGFR 3 mutation positive) underwent a comprehensive standardized neuropsychological evaluation. On average, while generally still within normal limits, significantly lower scores compared to standardized means were identified on: Full-scale IQ, verbal IQ, working memory, arithmetic, attention, executive functioning and aspects of day-to-day emotional, social, and behavioral functioning. Clinically significant levels of impairment at a group level were identified on measures of: arithmetic, attention, and executive functioning. There was variability among the group and for most measures scores ranged from impaired to within normal limits. A high percentage of children were impaired on measures of: verbal IQ, attention and executive functioning. Results of this study suggest a need for individual neuropsychological evaluation and monitoring of children with achondroplasia and suggest verbal IQ, arithmetic, attention, and executive functioning are particularly common areas of impairment. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

  9. Neuropsychological correlates of theory of mind in patients with early Parkinson's disease. (United States)

    Santangelo, Gabriella; Vitale, Carmine; Trojano, Luigi; Errico, Domenico; Amboni, Marianna; Barbarulo, Anna Maria; Grossi, Dario; Barone, Paolo


    The theory of mind is the ability to attribute mental states to oneself and others and to understand that others have beliefs, desires and intentions different from one's own. The aim of the study was to explore the neuropsychological correlates of theory of mind in patients affected by early Parkinson's disease (PD). Thirty-three PD patients and 33 age-, sex-, and education-matched control subjects underwent the Frontal Assessment Battery, as well as tasks assessing "cognitive" and "affective" theory of mind, and memory abilities; questionnaires evaluating behavioral disorders and quality of life were also administrated. Although the 2 groups did not differ on neuropsychological tasks, PD patients' performance on tasks assessing cognitive and affective theory of mind was significantly worse than controls. Moreover, PD patients had more behavioral disorders and worse quality of life than controls. After covarying for behavioral and quality of life scores, the differences between patients and controls on theory of mind tasks remained significant. "Cognitive" theory of mind was associated with Frontal Assessment Battery score and 2 domains of quality of life scale, whereas "affective" theory of mind scores correlated only with behavioral scales such as the Frontal Behavioral Inventory and Apathy Evaluation Scale. The results demonstrate that both affective and cognitive aspects of theory of mind are simultaneously impaired in early PD and suggest that deficits in the 2 subcomponents of theory of mind may be linked to dysfunction of different frontosubcortical circuitries in early PD.

  12. Transactional Neuropsychology, a Holistic View of Children with Developmental Disabilities

    Directory of Open Access Journals (Sweden)

    Gerardo Restrepo


    Full Text Available Introduction: The main objective of this article is to review some essential concepts to understan­ding the traditional way in which neuropsychology conceives difficulties in child development, and to propose an alternative model for integrally understanding this problematic. Development: Physicians, psychologists, therapists, and teachers conceive difficulties in development as a result of a neuro-biological problem that can be subject of identification and treatment. This premise, widely used currently by interdisciplinary staffs, is the prevailing focus and the traditional po­sition to evaluate and intervene in medicine, psychology and education. The traditional model, known as the deficit model, conceptualizes the difficulties in child development as being essentially neuro-biological, without considering the various aspects of both family and school environments, which are of paramount importance not only for the child development, but also in the genesis of its difficulties. This explains why efforts invested in the rehabilitation and education of the child with difficulties have a limited success. In contrast, the ecological or transactional neurop­sychology is an approach that considers the child in a comprehensive manner, relating with its social, family and cultural environment. Conclusion: Integrally conceptualizing and interpreting these phenomena leads to a holistic intervention where each element of the problem is assessed, leading to the proposal of a model in which the environment plays a crucial role in the genesis of the difficulties in child development, and the search for solutions.

  13. [Dyslexia: neuropsychological and neurolinguistic aspects]. (United States)

    Van Hout, A


    A brief review is given of the contribution of neuropsychological diagnostic methods and neurolinguistic diagnostic investigations. Through the analysis of errors, neurolinguistic examinations today make it possible to isolate in dyslexic populations at least three groups with clear-cut characteristics, requiring a distinct remedial approach. Neuropsychological investigations, and in particular their cross-matching with radiological neuro-imaging methods, serve to evidence the specificity of the cerebral organization of dyslexics.

  14. The A-B Neuropsychological Assessment Scale (ABNAS): the relationship between patient-percieved drug related cognitive impairment and results of neuropsychological tests

    NARCIS (Netherlands)

    Aldenkamp, A.P.; Meel, H.F. van; Baker, G.A.; Brooks, J.; Hendriks, M.P.H.


    Our intention was to evaluate the relationships between the A-B neuropsychological assessment schedule (ABNAS) as a measure of patient-perceived cognitive effects of antiepileptic drugs (AEDs) and the results of neuropsychological tests. The measure was developed specifically to assess

  15. Impaired Context Processing is Attributable to Global Neuropsychological Impairment in Schizophrenia and Psychotic Bipolar Disorder. (United States)

    Reilly, James L; Hill, S Kristian; Gold, James M; Keefe, Richard S E; Clementz, Brett A; Gershon, Elliot; Keshavan, Matcheri S; Pearlson, Godfrey; Tamminga, Carol A; Sweeney, John A


    Context processing may reflect a specific cognitive impairment in schizophrenia. Whether impaired context processing is observed across psychotic disorders or among relatives of affected individuals, and whether it is a deficit that is independent from the generalized neuropsychological deficits seen in psychotic disorders, are less established. Schizophrenia, schizoaffective, and psychotic bipolar probands (n = 660), their first-degree relatives (n = 741), and healthy individuals (n = 308) studied by the Bipolar-Schizophrenia Network on Intermediate Phenotypes consortium performed an expectancy task requiring use of contextual information to overcome a pre-potent response. Sensitivity for target detection and false alarm rates on trials requiring inhibition or goal maintenance were measured. Proband groups and relatives with psychosis spectrum personality traits demonstrated reduced target sensitivity and elevated false alarm rates. False alarm rate was higher under inhibition vs goal maintenance conditions although this difference was attenuated in schizophrenia and schizoaffective proband groups. After accounting for global neuropsychological impairment, as reflected by the composite score from the Brief Assessment of Cognition in Schizophrenia neuropsychological battery, deficits in schizophrenia and bipolar proband groups were no longer significant. Performance measures were moderately familial. Reduced target detection, but not a specific deficit in context processing, is observed across psychotic disorders. Impairments in both goal maintenance and response inhibition appear to contribute comparably to deficits in schizophrenia and schizoaffective disorder, whereas greater difficulty with response inhibition underlies deficits in bipolar disorder. Yet, these deficits are not independent from the generalized neurocognitive impairment observed in schizophrenia and psychotic bipolar disorder.

  16. Cognitive deficits in schizophrenia

    Directory of Open Access Journals (Sweden)

    S Chattopadhyay


    Full Text Available The term schizophrenia was coined by Eugene Bleuler. Symptoms of schizophrenia are arranged into groups or clusters called as domains. The domains of dysfunctions are positive symptoms, negative symptoms, cognitive impairments, mood and suicidity, and aggression. Cognition is the sum total of mental processes that makes us acquire knowledge and keeps us aware of our surroundings and thus enables us to arrive at appropriate judgments. Cognitive deficits are recognized as enduring and persistent features in schizophrenia and can be neuro-cognitive or relating to social cognition. Neurocognitive deficits are deficits in speed of processing, attention / vigilance, working memory, verbal memory, visual memory, reasoning and problem solving, social cognition. Cognitive function can be assessed by various methods like experimental approach, neuropsychological and psychometric and ecologic approach. Cognitive deficits are present at onset of illness producing substantial impairment. Unlike psychotic symptoms, which remit with treatment, functional impairments remain stable over time. Detail understanding of such symptoms will help in disability limitation. Various cognitive remediation programmes are underway with such intent. Articles till March, 2012 were searched through PubMed and Google Scholar, which were studied in an attempt of understanding the topic. The information was structured and organized.

  17. Patient satisfaction with a hospital-based neuropsychology service. (United States)

    Foran, Amie; Millar, Elisa; Dorstyn, Diana


    Objective The aim of the present study was to develop and pilot a measure of patient satisfaction that encompasses themes, activities, settings and interactions specific to the neuropsychological assessment process. Methods A focus group of out-patients (n=15) was surveyed to identify the factors commonly associated with a satisfactory neuropsychological experience. Responses informed a purposely designed 14-item patient satisfaction scale (α=0.88) that was completed by 66 hospital out-patients with mild to moderate cognitive impairment. Results Satisfaction with the neuropsychological assessment process was generally reported, with the testing phase (85%) rated significantly more favourably than the pre-assessment (79%) and feedback (70%) phases. Commentaries provided by 32 respondents identified interpersonal facilitators to a satisfactory neuropsychological assessment experience, but also dissatisfaction with physical aspects of the testing environment in addition to service availability. Conclusions The patient satisfaction scale can be used as a quality assurance tool to evaluate neuropsychological service delivery. Large-scale research is needed to confirm the scale's psychometric properties. Further research may also include a broader perspective on the consumers' experience of neuropsychological services.

  18. Development and evaluation of the LiSN & learn auditory training software for deficit-specific remediation of binaural processing deficits in children: preliminary findings. (United States)

    Cameron, Sharon; Dillon, Harvey


    The LiSN & Learn auditory training software was developed specifically to improve binaural processing skills in children with suspected central auditory processing disorder who were diagnosed as having a spatial processing disorder (SPD). SPD is defined here as a condition whereby individuals are deficient in their ability to use binaural cues to selectively attend to sounds arriving from one direction while simultaneously suppressing sounds arriving from another. As a result, children with SPD have difficulty understanding speech in noisy environments, such as in the classroom. To develop and evaluate the LiSN & Learn auditory training software for children diagnosed with the Listening in Spatialized Noise-Sentences Test (LiSN-S) as having an SPD. The LiSN-S is an adaptive speech-in-noise test designed to differentially diagnose spatial and pitch-processing deficits in children with suspected central auditory processing disorder. Participants were nine children (aged between 6 yr, 9 mo, and 11 yr, 4 mo) who performed outside normal limits on the LiSN-S. In a pre-post study of treatment outcomes, participants trained on the LiSN & Learn for 15 min per day for 12 weeks. Participants acted as their own control. Participants were assessed on the LiSN-S, as well as tests of attention and memory and a self-report questionnaire of listening ability. Performance on all tasks was reassessed after 3 mo where no further training occurred. The LiSN & Learn produces a three-dimensional auditory environment under headphones on the user's home computer. The child's task was to identify a word from a target sentence presented in background noise. A weighted up-down adaptive procedure was used to adjust the signal level of the target based on the participant's response. On average, speech reception thresholds on the LiSN & Learn improved by 10 dB over the course of training. As hypothesized, there were significant improvements in posttraining performance on the LiSN-S conditions

  19. Indications and expectations for neuropsychological assessment in routine epilepsy care: Report of the ILAE Neuropsychology Task Force, Diagnostic Methods Commission, 2013-2017. (United States)

    Wilson, Sarah J; Baxendale, Sallie; Barr, William; Hamed, Sherifa; Langfitt, John; Samson, Séverine; Watanabe, Masako; Baker, Gus A; Helmstaedter, Christoph; Hermann, Bruce P; Smith, Mary-Lou


    The International League Against Epilepsy (ILAE) Diagnostic Methods Commission charged the Neuropsychology Task Force with the job of developing a set of recommendations to address the following questions: (1) What is the role of a neuropsychological assessment? (2) Who should do a neuropsychological assessment? (3) When should people with epilepsy be referred for a neuropsychological assessment? and (4) What should be expected from a neuropsychological assessment? The recommendations have been broadly written for health care clinicians in established epilepsy settings as well as those setting up new services. They are based on a detailed survey of neuropsychological assessment practices across international epilepsy centers, and formal ranking of specific recommendations for advancing clinical epilepsy care generated by specialist epilepsy neuropsychologists from around the world. They also incorporate the latest research findings to establish minimum standards for training and practice, reflecting the many roles of neuropsychological assessment in the routine care of children and adults with epilepsy. The recommendations endorse routine screening of cognition, mood, and behavior in new-onset epilepsy, and describe the range of situations when more detailed, formal neuropsychological assessment is indicated. They identify a core set of cognitive and psychological domains that should be assessed to provide an objective account of an individual's cognitive, emotional, and psychosocial functioning, including factors likely contributing to deficits identified on qualitative and quantitative examination. The recommendations also endorse routine provision of feedback to patients, families, and clinicians about the implications of the assessment results, including specific clinical recommendations of what can be done to improve a patient's cognitive or psychosocial functioning and alleviate the distress of any difficulties identified. By canvassing the breadth and depth

    Children with HIV infection (HIV+) are at neuropsychological risk, but few studies have evaluated this at multiple sites in low-income and middle-income countries. We compared neuropsychological outcomes at enrollment (>5 years age) among HIV+, HIV perinatally exposed uninfected (HEU), and HIV unexposed uninfected (HUU) children from four sub-Saharan countries. IMPAACT P1060 compared nevirapine versus lopinavir/ritonavir-based antiretroviral treatment (ART) in HIV-infected children 6-35 months of age. The present study (P1104s) enrolled P1060 children at 5-11 years of age and evaluated their neuropsychological performance over 2 years using the Kaufman Assessment Battery for Children, 2nd edition (KABC-II), Tests of Variables of Attention (TOVA), Bruininks-Oseretsky Test, 2nd edition (BOT-2), and parent-reported Behavior Rating Inventory of Executive Function (BRIEF). Cohorts were compared using generalized estimating equations least-squares means adjusted for site, child age and sex, and personal and social characteristics for child and caregiver. Six hundred and eleven (246 HIV+, 183 HEU, 182 HUU) of the 615 enrolled at six sites [South Africa (three), Zimbabwe, Malawi, Uganda] were available for analysis. Mean age was 7.2 years, 48% male, 69% in school. Unadjusted and adjusted comparisons were consistent. HIV+ children performed significantly worse than HEU and HUU cohorts on all KABC-II cognitive performance domains and on BOT-2 total motor proficiency (P < 0.001), but not on the BRIEF Global Executive Indices. HUU and HEU cohorts were comparable on cognitive outcomes. HIV+ children initiated on ART before 1 year of age had significantly better BRIEF evaluations (lower scores - fewer behavior problems), compared with those started after (P = 0.03). Significant cognitive deficits were documented among HIV+ children at school age, even when started on ART at an early age. Earlier HIV treatment, neuropsychological monitoring, and rehabilitative

  1. Evaluation of the double-deficit hypothesis in college students referred for learning difficulties. (United States)

    Cirino, Paul T; Israelian, Marlyne K; Morris, Mary K; Morris, Robin D


    The present study explored the double-deficit hypothesis (DDH) in a sample of 146 college students with and without reading disabilities (RD). The results indicated that although both phonological awareness (PA) and visual naming speed (VNS) contributed to performance on measures of decoding and comprehension, their relative contribution was influenced both by the nature of the stimulus (word vs. nonword vs. text) and by the conditions of the task (timed vs. untimed). Similar results were obtained using an individual differences approach, or when between-group comparisons were made of individuals with deficits in PA or VNS. The relative representation of DDH subgroups in groups of adults with RD varied based on the classification criteria used to define RD. These results support the DDH, extend its applicability to adults, and have implications for diagnostic decision making.

  3. Reducing attention deficits after stroke using attention process training: a randomized controlled trial. (United States)

    Barker-Collo, Suzanne L; Feigin, Valery L; Lawes, Carlene M M; Parag, Varsha; Senior, Hugh; Rodgers, Anthony


    Impaired attention contributes to poor stroke outcomes. Attention process training (APT) reduces attention deficits after traumatic brain injury. There was no evidence for effectiveness of APT in stroke patients. This trial evaluated effectiveness of APT in improving attention and broader outcomes in stroke survivors 6 months after stroke. Participants in this prospective, single-blinded, randomized, clinical trial were 78 incident stroke survivors admitted over 18 months and identified via neuropsychological assessment as having attention deficit. Participants were randomly allocated to standard care plus up to 30 hours of APT or standard care alone. Both groups were impaired (z attention at baseline, with the exception of Paced Auditory Serial Addition Test, which was below average (z Attention Quotient. APT resulted in a significantly greater (Pattention and broader outcomes were not significant. APT is a viable and effective means of improving attention deficits after incident stroke.

    Directory of Open Access Journals (Sweden)

    M. Tajik Khaveh


    Full Text Available In order to evaluate the effects of biofertilizer on soybean (Glycine max L. seed vigor that produced under water deficit condition and related traits, an experiment was conducted in a factorial layout based of complete randomized block design with four replications at the research greenhouse of Aboureihan campus- Tehran University, Iran. Experimental treatments were include biofertilizer (seed inoculation with Bradyrhizobium japonicum, co-inoculation with Bradyrhizobium japonicum and Pseudomonas fluorescens, co-inoculation with Bradyrhizobium japonicum and Glomus mosseae, Cultivar (Zalta Zalha and Clark×Hobbit line and water deficit stress [irrigation plants after 50 (normal irrigation, 100 (medium stress, 150 (sever stress mm evaporation from pan class A, in parents field]. Results showed that the water deficit stress had negative effects on seed quality and seedling emergence percentage, mean daily seedling emergence, root, leaf and shoot dry weight, number of nodule were decreased. ZaltaZalha cultivar had higher shoot dry weight and number of leaf compared with other cultivars. Applications of biofertilzer was effective on stem diameter, root, leaf and shoot dry weight, number of leaf and nodule and those attributes increased by co-inoculation of Bradyrhizobium japonicum and Glomus mosseae. Also, use of biofertilizer in stress levels was effective on stem dry weight. Stem dry weight was increased by Co-inoculation of cultivar seeds with Bradyrhizobium japonicum and Glomus mosseae.

  5. [Evaluation of the Musical Concentration Training with Pepe (MusiKo mit Pepe) for children with attention deficits]. (United States)

    Rothmann, Kathrin; Hillmer, Jana-Mareike; Hosser, Daniela


    This study evaluates the Musical Concentration Training with Pepe ("MusiKo mit Pepe") for children aged 5 to 10 years with attention deficits. Using a pre-post-control design (N = 108), changes in attention capacity are measured by the Test of Attentional Performance for Children (KiTAP), whereas changes in the quality of life are assessed with the Children's Questionnaire (KINDL-R). Additionally, we utilized the Symptom Checklist for Attention Deficit Hyperactivity Disorders (FBB-ADHS) and for Conduct Disorder (FBB-SSV) of the Diagnostic System of Mental Disorders in Children and Adolescents II based on ICD-10 and DSM-IV as well as the Child Behavior Checklist and the Teacher's Report Form (CBCL, TRF). Significant pre-post effects were found in both attention and quality of life for children treated by the training compared to controls. Moreover, significant reductions were detected in ADHD symptomatology in parents' and teachers' ratings, and in internal problems in parents' ratings. The effectiveness of the intervention was not affected by age, sex, intelligence, or migration background. The music-based training "MusiKo mit Pepe" is an effective intervention for children with attention deficits, pending replication of these findings in future studies.

  6. Eliminating Electricity Deficit through Energy Efficiency in India: An Evaluation of Aggregate Economic and Carbon Benefits

    Energy Technology Data Exchange (ETDEWEB)

    Sathaye, Jayant; Gupta, Arjun


    Electricity demand has consistently exceeded available supply in India. While the electricity deficit varies across states, nationally it was estimated to be of the order of 12percent on peak and 11percent for electricity during 2008-09. This paper explores a demand-side focused potential for energy efficiency improvement to eliminate the electricity deficit compared to a business as usual (BAU) supply-side focused scenario. The limited availability of finance and other legal and administrative barriers have constrained the construction of new power plant capacity in India. As a result, under the BAU scenario, India continues to face an electricity deficit beyond the end of the Twelfth Five Year Plan. The demand-side cost-effective potential achieved through replacement of new electricity-using products, however, is large enough to eliminate the deficit as early as 2013 and subsequently reduce the future construction of power plants and thus reduce air pollutant emissions. Moreover, energy efficiency improvements cost a fraction of the cost for new supply and can lead to a substantial increase in India's economic output or gross domestic product (GDP). Eliminating the deficit permits businesses that have experienced electricity cutbacks to restore production. We estimate the size of the cumulative production increase in terms of the contribution to GDP at a $505 billion between 2009 and 2017, the end of India's Twelfth Five Year Plan, which may be compared with India's 2007-08 GDP of $911 billion. The economic output is influenced by the size of the electricity savings and rate of penetration of energy efficient technologies, and that of self-generation equipment and inverters used by businesses faced with electricity cuts. Generation and inverters are estimated to service 23percent of these customers in 2009, which increase to 48percent by 2020. The reduction in the construction and operation of new power plants reduces the cumulative CO2 emissions

  7. Cognitive impairment in cerebellar lesions: a logit model based on neuropsychological testing. (United States)

    Bolceková, Eva; Mojzeš, Matej; Van Tran, Quang; Kukal, Jaromír; Ostrý, Svatopluk; Kulišťák, Petr; Rusina, Robert


    Damage to the cerebellum may lead to motor dysfunctions, but also to the neuropsychological deficits that comprise the Cerebellar Cognitive Affective Syndrome (CCAS). It can affect executive functions, attention, memory, visuospatial functions, language, and emotions. Our goal was to determine which neuropsychological tests could be effectively used to identify this syndrome during a short examination. Twenty-five patients with an isolated cerebellar lesion and 25 matched healthy controls were examined using an extensive neuropsychological battery. Logistic regression models and sub-models were computed for individual tests, as well as for the full battery. The best results were produced by a model combining patient education level, the number of errors on the California Verbal Learning Test, and time on Prague Stroop Test (Dots). Based on the results, we suggest that a condensed battery of neuropsychological tests can be used to detect CCAS. The tests are easy to administer and could be helpful in both research and clinical settings.

  8. Neuropsychological correlates of domestic violence. (United States)

    Cohen, R A; Rosenbaum, A; Kane, R L; Warnken, W J; Benjamin, S


    Neuropsychological functioning was assessed in 39 males who had committed domestic violence (batterers) and compared to 63 nonviolent (both maritally discordant and satisfied) subjects recruited by advertisement. Subjects were subsequently divided into two groups (head injured, nonhead injured) and these groups were also contrasted as a function of batterer status. Tests were administered to assess for cognitive and behavioral functions, including executive dysfunction, hypothesized to be a factor contributing to propensity for violence. Questionnaires and structured clinical interviews were used to assess marital discord, emotional distress, and violent behaviors. Batterers differed from nonbatterers across several cognitive domains: executive, learning, memory, and verbal functioning. Batterers were reliably discriminated from nonbatterers based on three neuropsychological tasks: Digit Symbol, Recognition Memory Test-Words, Wisconsin Card Sorting Test. Neuropsychological performance was the strongest correlate of domestic violence of all clinical variables measured. However, the inclusion of two other variables, severity of emotional distress and history of head injury, together with the neuropsychological indices provided the strongest correlation with batterers status. Among batterers, neuropsychological performance did not vary as a function of head injury status, indicating that while prior head injury was correlated with batterer status, it was not the sole basis for their impairments. The findings suggest that current cognitive status, prior brain injury, childhood academic problems, as well as psychosocial influences, contribute along with coexisting emotional distress to a propensity for domestic violence.

  9. Neuropsychology and emotion processing in violent individuals with antisocial personality disorder or schizophrenia: The same or different? A systematic review and meta-analysis. (United States)

    Sedgwick, Ottilie; Young, Susan; Baumeister, David; Greer, Ben; Das, Mrigendra; Kumari, Veena


    To assess whether there are shared or divergent (a) cognitive and (b) emotion processing characteristics among violent individuals with antisocial personality disorder and/or schizophrenia, diagnoses which are commonly encountered at the interface of mental disorder and violence. Cognition and emotion processing are incorporated into models of violence, and thus an understanding of these characteristics within and between disorder groups may help inform future models and therapeutic targets. Relevant databases (OVID, Embase, PsycINFO) were searched to identify suitable literature. Meta-analyses comparing cognitive function in violent schizophrenia and antisocial personality disorder to healthy controls were conducted. Neuropsychological studies not comparing these groups to healthy controls, and emotion processing studies, were evaluated qualitatively. Meta-analyses indicated lower IQ, memory and executive function in both violent schizophrenia and antisocial personality disorder groups compared to healthy controls. The degree of deficit was consistently larger in violent schizophrenia. Both antisocial personality disorder and violent schizophrenia groups had difficulties in aspects of facial affect recognition, although theory of mind results were less conclusive. Psychopathic traits related positively to experiential emotion deficits across the two disorders. Very few studies explored comorbid violent schizophrenia and antisocial personality disorder despite this being common in clinical practice. There are qualitatively similar, but quantitatively different, neuropsychological and emotion processing deficits in violent individuals with schizophrenia and antisocial personality disorder which could be developed into transdiagnostic treatment targets for violent behaviour. Future research should aim to characterise specific subgroups of violent offenders, including those with comorbid diagnoses.

  10. The profession of neuropsychology in Spain: results of a national survey. (United States)

    Olabarrieta-Landa, Laiene; Caracuel, Alfonso; Pérez-García, Miguel; Panyavin, Ivan; Morlett-Paredes, Alejandra; Arango-Lasprilla, Juan Carlos


    To examine the current status of professional neuropsychology in Spain, with particular focus on the areas of professional training, current work situation, evaluation and diagnostic practice, rehabilitation, teaching, and research. Three hundred and thirty-nine self-identified professionals in neuropsychology from Spain completed an online survey between July and December of 2013. Respondents had an average age of 35.8 years and 77% were women. Ninety-seven percent of the respondents identified as psychologists; 82% of the sample had a master's degree, and 33% a doctoral degree. The majority (91%) received their neuropsychological training at a graduate level; 88% engaged in neuropsychological evaluation, 59% in rehabilitation, 50% in research, and 40% in teaching. Average number of hours per week dedicated to work in neuropsychology was 29.7, with 28% of the respondents reporting working in hospitals, 17% in not-for-profit rehabilitation centers, 15% in universities, and 14% in private clinics. Clinicians primarily work with individuals with stroke, traumatic brain injury, and dementia. The top perceived barriers to development of neuropsychology in Spain included lack of clinical and academic training opportunities, and negative attitude toward professional collaboration. The field of neuropsychology in Spain is young and rapidly growing. There is a need to regulate professional neuropsychology, improve graduate curricula, enhance existing clinical training, develop professional certification programs, validate and create normative data for existing neuropsychological tests, and create new, culturally relevant instruments.

  11. [Capgras syndrome: a proposal of neuropsychological battery for assessment]. (United States)

    Hillers Rodríguez, Rosalía; Madoz-Gúrpide, Agustín; Tirapu Ustárroz, Javier


    Capgras syndrome is the most prevalent of the delusional misidentification syndromes. It appears in both psychiatric illness and organic brain damage. Cognitive and neuropsychiatric models (lateralization and disconnection) have been proposed to explain the syndrome. From a neuropsychological point of view Capgras syndrome seems to be due to damage of bifrontal and right limbic and temporal regions. Memory, feeling of familiarity, monitoring of self and reality would be altered. All of these cause a failure to adequately integrate the information about emotions and facial recognition. Relative preservation of the left frontal lobe may be necessary for the development of delusional response. There does not seem to be a differential pattern as regards the aetiology, but there is a common underlying neuropsychiatric mechanism. Based on theoretic models, and clinics features, we propose a neuropsychological battery to assess the Capgras syndrome, that should be sensitive to the main expected deficits. Copyright © 2011 SEGG.

  12. Fetal Alcohol Spectrum Disorders: Neuropsychological and Behavioral Features (United States)

    Mattson, Sarah N.; Crocker, Nicole; Nguyen, Tanya T.


    Heavy prenatal alcohol exposure can cause alterations to the developing brain. The resulting neurobehavioral deficits seen following this exposure are wide-ranging and potentially devastating and, therefore, are of significant concern to individuals, families, communities, and society. These effects occur on a continuum, and qualitatively similar neuropsychological and behavioral features are seen across the spectrum of effect. The term fetal alcohol spectrum disorders (FASD) has been used to emphasize the continuous nature of the outcomes of prenatal alcohol exposure, with fetal alcohol syndrome (FAS) representing one point on the spectrum. This paper will provide a comprehensive review of the neuropsychological and behavioral effects of heavy prenatal alcohol exposure, including a discussion of the emerging neurobehavioral profile. Supporting studies of lower levels of exposure, brain-behavior associations, and animal model systems will be included when appropriate. PMID:21503685

  15. Italian neuropsychology in the second half of the twentieth century. (United States)

    Vallar, Giuseppe; Boller, François; Grossi, Dario; Gainotti, Guido


    Since the early 1960s, human neuropsychology, the study of brain-behavior interrelations, mainly based on the analysis of their pathological variations, brought about by brain damage, has had a remarkable systematical development in Italy. All this started in Milan, with the neurologist Ennio de Renzi, and his collaborators (Luigi Vignolo, then Anna Basso, Pietro Faglioni, Hans Spinnler, François Boller, and, more autonomously, Edoardo Bisiach), in the Clinic of Nervous and Mental Diseases. Scientists of the "Milan group" investigated several neuropsychological deficits caused by focal hemispheric lesions in large series of left- and right-brain-damaged patients, and control participants, comparable for cultural and demographic variables. Standardized tests and advanced statistical methods were used, which also applied to the diagnosis and rehabilitation of aphasia. Subsequently, neuropsychology developed in Italy extensively, reaching high international reputation. Leading neuropsychologists have been the neurologists Guido Gainotti (Rome), and Franco Denes (Padua), the physicians and psychologists Luigi Pizzamiglio (Rome), and Carlo Umiltà (Parma, with fruitful interactions with the neurophysiologists Giovanni Berlucchi, Giacomo Rizzolatti, and Carlo Marzi, from the school of Giuseppe Moruzzi in Pisa) A second scientific generation of neuropsychologists has then developed in the 1970s, trained by the abovementioned scientists, further boosting and spreading high-level basic and applied research (diagnosis and rehabilitation of neuropsychological deficits of patients with brain damage or dysfunction throughout the life span, from childhood to the elderly). Available techniques include structural and functional imaging (CT, PET, SPET, MRI and fMRI Scans, DTI), electrophysiological recording (EEG, ERPs), non-invasive brain stimulation (TMS, tES), and their combined use.

  16. Neuropsychological Assessment Following Concussion: an Evidence-Based Review of the Role of Neuropsychological Assessment Pre- and Post-Concussion. (United States)

    Kontos, Anthony P; Sufrinko, Alicia; Womble, Melissa; Kegel, Nathan


    Neuropsychological evaluation is one component of a comprehensive and multifaceted assessment following concussion. Although some neuropsychologists use a "hybrid" assessment approach integrating computerized neurocognitive testing batteries with traditional paper and pencil tests, computerized neurocognitive test batteries are the predominant testing modality for assessment of athletes from the youth to professional level. This review summarizes the most recent research supporting the utility of neuropsychological evaluation and highlights the strengths and weaknesses of both computerized and traditional neuropsychological testing approaches. The most up to date research and guidelines on baseline neurocognitive testing is also discussed. This paper addresses concerns regarding reliability of neuropsychological testing while providing an overview of factors that influence test performance, both transient situational factors (e.g., pain level, anxiety) and characteristics of particular subgroups (e.g., age, preexisting learning disabilities), warranting the expertise of an experienced neuropsychologist for interpretation. Currently, research is moving forward by integrating neuropsychological evaluation with emerging assessment approaches for other domains of brain function (e.g., vestibular function) vulnerable to concussion.

  17. Narcolepsy: Pathophysiology and Neuropsychological Changes

    Directory of Open Access Journals (Sweden)

    Angela Naumann


    Full Text Available Narcolepsy is now recognized as a distinctive disorder with specific pathophysiology and neurochemical abnormalities. Findings on the role of the neuropeptide hypocretin are opening new avenues of research and new strategies for therapy. Recently, neuropsychological and electrophysiological studies have provided evidence for reduced memory performance on standard memory tests in addition to subjective complaints of forgetfulness which may be related to changes in attentional processing. Further studies are, however, necessary to clarify the neuropsychological profile in narcolepsy. This review focuses on the recent advances in understanding narcolepsy.

  18. [Neuropsychological profile of internationally adopted children in Catalonia]. (United States)

    Callejón-Póo, L; Boix, C; López-Sala, A; Colomé, R; Fumadó, V; Sans, A


    During the last years, International adoption has increased significantly in our country over the last few years. China, Russia, Colombia and Ethiopia represent 77% of international adoptions in Spain. Cognitive and behavioural aspects are very important for an adequate social, family and school integration of these children. To describe the neuropsychological profiles of a group of internationally adopted children in Catalonia from China, Russia, Colombia and Ethiopia. Neuropsychological examination of 49 children from international adoption (6 of Chinese origin, 24 from Russia, 13 from Colombia and 6 of Ethiopian origin). The group of Chinese origin obtained average scores of all functions evaluated. The Russian origin group was below the average for, selective attention, phonetic verbal fluency, control of impulsivity, mechanics and reading comprehension, and spelling. Scores on the impulse control in the Colombian origin group were below average. The group of Ethiopian origin obtained average scores in all functions evaluated except for spelling difficulties. Children adopted from Russia have greater neuropsychological difficulties than the others. Most pre-adoption history is unknown; therefore we are unable to determine the origin of these difficulties. Maternal alcohol consumption during pregnancy and the institutional environment could be influencing factors in neuropsychological delay. Inclusion of neuropsychological assessment in health protocols for these children is recommended if they develop suggestive signs of cognitive and/or behavioral impairment.

    Davalos, I P; Figuera, L E; Bobadilla, L; Martinez-Martinez, R; Matute, E; Partida, M G; Bañuelos, L A; Ramirez-Dueñas, M L


    We describe a six year old Mexican girl whose clinical picture (short stature with delayed bone age, language difficulties and triangular face with prominent nose) was compatible with the diagnosis of Floating-Harbor Syndrome (FHS). A neuropsychological evaluation disclosed a mild mental retardation, a constructive apraxia, a comprehensive and expressive language impairment. The analysis of the present case and sixteen patients previously described establishes that the FHS is mainly characterized by proportionate short stature with significantly delayed bone age, delayed expressive language and peculiar face.

    Yudiarto, Fenny L; Muliadi, L; Moeljanto, D; Hartono, B


    to evaluate attention, concentration, memory changes and executive function inpatients with hyperthyroidism compared with normal thyroid function patients. a cross sectional study was conducted in 21 patients (14F, 7M) with symptoms of sweating, sleep disturbance, fine tremor, headache, palpitation, nervousness, forgetfulness and diarrhea. Neurological examination found that 2 patients had proximal paresis and periodic paralysis. Their thyroid functions (FT4 and TSHS) were done, 13 patients were hyperthyroid, 2 patients were subclinical hyperthyroid and 6 patients were euthyroid. Neuropsychological tests such as: Mini Mental State Examination (MMSE), Trail Making Test (TMT) A and B, Continuous Performance Test (CPT), Vigilance Complex Task (VCT), Digit Forward and Backward Repetition (DFR, DBR) were performed in all of those patients. The mean age of sample was 47,3 +/- 8,45 years old and all of them had minimal 6 years education background, no history of cerebro vascular disease, brain injury or tumour or infection, epilepsy, cerebral degeneration, and taking neuroleptics or antidepressants. using the Kendall correlation coefficients showed that FT4 had negative correlation with VCT, CPT, DFR, DBR and positive correlation with TMT A (time) and TMT B (time and error). Study T-test showed that high level of thyroid function had significant difference in TMT A (time), TMT B (time), DBR, DFR, VCT, CPT. Fischer exact gave statistically significant in VCT and fine tremor in hyperthyroid patients (RR VCT 5.60, 95% CI 0.93-33.68, RR fine tremor 0.50, 95% CI 0.28-0.88). hyperthyroid patients had significant decrease on attention, concentration, verbal memory and executive function (working memory) compared with euthyroid patients.

  3. Cognitive domain deficits in patients with aneurysmal subarachnoid haemorrhage at 1 year (United States)

    Wong, George Kwok Chu; Lam, Sandy Wai; Ngai, Karine; Wong, Adrian; Siu, Deyond; Poon, Wai Sang; Mok, Vincent


    Background Cognitive domain deficits can occur after aneurysmal subarachnoid haemorrhage (aSAH) though few studies systemically evaluate its impact on 1-year outcomes. Objective We aimed to evaluate the pattern and functional outcome impact of cognitive domain deficits in aSAH patients at 1 year. Methods We carried out a prospective observational study in Hong Kong, during which, 168 aSAH patients (aged 21–75 years and had been admitted within 96 h of ictus) were recruited over a 26-month period. The cognitive function was assessed by a domain-specific neuropsychological assessment battery at 1 year after ictus. The current study is registered at of the US National Institutes of Health (NCT01038193). Results Prevalence of individual domain deficits varied between 7% to 15%, and 13% had two or more domain deficits. After adjusting for abbreviated National Institute of Health Stroke Scale and Geriatric Depressive Scale scores, unfavourable outcome (Modified Rankin Scale 3–5) and dependent instrumental activity of daily living (Lawton Instrumental Activity of Daily Living<15) were significantly associated with two or more domain deficits and number of cognitive domain deficits at 1 year. Two or more domain deficits was independently associated with age (OR, 1.1; 95% CI 1.1 to 1.2; p<0.001) and delayed cerebral infarction (OR, 6.1; 95% CI 1.1 to 33.5; p=0.036), after adjustment for years of school education. Interpretation In patients with aSAH, cognitive domain deficits worsened functional outcomes at 1 year. Delayed cerebral infarction was an independent risk factor for two or more domain deficits at 1 year. PMID:23606736

  4. Evaluation of attitudes towards treatment in adolescents with attention deficit hyperactivity disorder (ADHD). (United States)

    Ferrin, Maite; Ruiz-Veguilla, Miguel; Blanc-Betes, Maria; Abd, Samaa El; Lax-Pericall, Teresa; Sinclair, Maxine; Taylor, Eric


    A substantial proportion of adolescents with attention deficit hyperactivity disorder (ADHD) do not appropriately adhere to prescribed treatments, especially to pharmacological treatments. It is important to disentangle the specific attitudes that contribute to treatment adherence. A 33-item questionnaire was applied to 120 adolescents diagnosed with ADHD and their respective parents. Reliability of the scale was explored using factor analysis, Cronbach's alpha, and test-retest. Validity was explored by face validity and the known-groups method. For the young people's version, three main dimensions (preoccupations, insight and self-concept) emerged. The parents' version showed six main dimensions (child's personal attitudes, worries, social stigma, insight, future side effects and knowledge). The potential of this questionnaire to explore the attitudes of patients and their families towards treatments and for clinicians to predict treatment adherence is discussed.

  6. Neuropsychological Profile of Lifetime Traumatic Brain Injury in Older Veterans. (United States)

    Kaup, Allison R; Peltz, Carrie; Kenney, Kimbra; Kramer, Joel H; Diaz-Arrastia, Ramon; Yaffe, Kristine


    The aim of this study was to characterize the neuropsychological profile of lifetime traumatic brain injury (TBI) in older Veterans. Participants were 169 older Veterans [mean age=79.1 years (range, 51-97 years), 89% male, 92% Caucasian], 88 with lifetime TBI and 81 without TBI, living in Veterans' retirement homes in independent residence. TBI history was ascertained with the Ohio State TBI Identification Method structured interview. Cognition was assessed with neuropsychological tests: Raw scores were converted to Z-scores compared to age-corrected normative data and combined into five domain composite Z-scores (attention/working memory, learning/memory, language, processing speed, executive functioning). We investigated the association between TBI and performance in each cognitive domain in linear mixed effects models, with and without adjustment for demographics, medical comorbidities, and psychiatric variables. Compared to those without TBI, older Veterans with TBI had greater deficits in processing speed (estimate=-.52; p=.01; f 2=.08 in fully adjusted model) and executive functioning (estimate=-.41; p=.02; f 2=.06 in fully adjusted model) but performed similarly in the attention/working memory, learning/memory, and language domains (all p>.05). TBI-associated deficits were most prominent among individuals with multiple mild TBIs and those with any moderate-to-severe TBI, but were not clearly present among those with single mild TBI. The neuropsychological profile of lifetime TBI in older Veterans is characterized by slowed processing speed and executive dysfunction, especially among those with greater injury burden. This pattern may reflect long-standing deficits or a TBI-associated cognitive decline process distinct from Alzheimer's disease. (JINS, 2017, 23, 56-64).

    Numerous studies have documented that children with attention deficit hyperactivity disorder (ADHD) show a low social competence. To compare the symptomatic severity of ADHD, as well as associations to different subtypes, sex and comorbidities, with social functioning ("ability" and "leadership") estimated through a Behavior Assessment System for Children (BASC) for parents and teachers. We have retrospectively analyzed 170 patients with ADHD, diagnosed between 2007 and 2010. Social "ability," "leadership," "hyperactivity" and "attention deficit" sections of BASC and cardinal symptoms of ADHD measured through a Spanish scale for de evaluation of DHD (E-DHD) were registered. Results of these variables are analyzed according to the normative data by age and sex, and processed in Z values. The ratings for social skills were significantly lower in patients with conduct disorder or oppositional defiant disorder as informed by parents (pleadership" as parents and teachers. Intensity of attention deficit was the only variable that showed a significant relation with the social skills and leadership according to the BASC scores, independently of the informer.

    Full Text Available Introduction The aging process causes structural and functional changes in the organism. Among these changes, the systems responsible for controlling the balance are also affected, especially in women. This study aims to perform an assessment and physiotherapy intervention in elderly with balance deficits through Berg scale and platform Wii Balance Board. Materials and methods The study was longitudinal quasi-experimental intervention. Held in the city of Passo Fundo, RS - Brazil. Participants were 38 elderly women who had a deficit balance. The instruments used to collect data was a questionnaire to identify, assess balance across the Berg Balance Scale and an intervention program with six games via the Wii Balance Board™ platform. To statistically analyze the effects before and after the intervention were used Wilcoxon and Pearson correlation, with a significance level of p = 0.05. Results In the present study, we observed a statistically significant improvement in the balance of elderly compared before and after intervention, moreover, the six games played also showed statistical significance when comparing the first and twentieth session, highlighting the games Tightrope Walk Table Tilt, Deep Breathing and Soccer Heading. Conclusion The evaluation and balance training with the platform Wii Balance Board were able to provide significant results for the elderly, besides, the game has the potential to treat the health, well-being and functional capacity of older people through the visual representation the game in real time.

  14. A pilot evaluation of the role of bracing in stable thoracolumbar burst fractures without neurological deficit. (United States)

    Shamji, Mohammed F; Roffey, Darren M; Young, Darryl K; Reindl, Rudy; Wai, Eugene K


    Prospective, 2-center, observer-blinded, randomized controlled trial. Investigate clinical and radiologic outcomes of bracing versus no-bracing in the treatment of stable thoracolumbar burst fractures. Management of thoracolumbar burst fractures depends upon clinical presentation of neurological deficit and radiographic features of fracture severity. Neurologically intact patients with mild deformity and biomechanical stability may be treated with conservative therapy. Patients with stable (AO type A3), single level, thoracolumbar burst fractures between T12 and L2 with no neurological deficit were randomized to nonoperative treatment with a customized thoracolumbosacral orthosis (TLSO) or no-brace. Self-reported clinical outcomes of pain, disability, and health-related quality of life, and radiographic outcomes of kyphotic progression and loss of vertebral height, assessed by 2 independent reviewers blinded to treatment group, were measured at 6 months follow-up. Twenty-three consecutive eligible patients were included (TLSO: n=12; no-brace: n=11). There were no between-group differences regarding level of injury (P=0.75) and baseline spine geometry including fractional canal compromise (P=0.49), anterior loss of vertebral body height (P=0.28), and sagittal Cobb angle (P=0.13). In-hospital stay was significantly shorter in the no-brace group (mean: 2.8±3.0 d) compared with the TLSO group (mean: 6.3±2.1 d; P=0.004). At follow-up there were no differences in anterior loss of vertebral body height (TLSO: 12.5%±10.2% vs. no-brace: 11.9%±8.1%; P=0.88), kyphotic progression (TLSO: 5.3±4.4 degrees vs. no-brace 5.2±3.6 degrees; P=0.93), adverse events, or self-reported clinical outcomes. Neurologically intact patients with stable thoracolumbar burst fractures treated with or without bracing had similar radiographic and clinical outcomes at 6 months follow-up. The no-brace group had shorter in-hospital lengths of stay. Conservative therapy involving early

    Full Text Available This paper aims to review the neuropsychological evaluation process in Alzheimer (AD patients, specifically that related to episodic and semantic memory. Alzheimer-style dementia is the main form of dementia, and is nowadays one of the most important social, cultural and health-related problems. Diagnosis and differentiation from normal aging are difficult in the initial stages, and so neuropsychological evaluation is key. The criteria currently utilized are those of the DSM IV (American Psychiatric Association, 1994 and of the NINCDS-ADRDA (Instituto Nacional para los Desórdenes Neurológicos, de la Comunicación y el Accidente Cerebro Vascular y la Asociación para la Enfermedad de Alzheimer y Desórdenes Relacionados (McKhann G, Drachman D, Folstein M, y col., 1984, and they require that the diagnosis of probable AD be confirmed by neuropsychological evaluation in addition to clinical evaluation and other studies. After the division of long term memory into semantic and episodic memory was made, specific tests were created for their neuropsychological evaluation in different pathologies, including AD. An important contribution to the early detection of memory deterioration typical of such illness was thus made.

  16. Research Review: Neuropsychological test performance in pediatric obsessive-compulsive disorder--a meta-analysis. (United States)

    Abramovitch, Amitai; Abramowitz, Jonathan S; Mittelman, Andrew; Stark, Abigail; Ramsey, Kesley; Geller, Daniel A


    Research into the neuropsychology of pediatric obsessive-compulsive disorder (OCD) reveals inconsistent results, limiting the ability to draw conclusions about possible neurocognitive deficits in youth with OCD. The aim of this study was to conduct a meta-analysis of the available literature. We identified 36 studies, of which 11 studies met inclusion criteria. Results were categorized into nine functional subdomains: planning, response inhibition/interference control, set shifting/cognitive flexibility, verbal memory, nonverbal memory, processing speed, working memory, visuospatial functions, and attention. For each domain, weighted pooled Hedges' g effect size was calculated using random model analyses. Small effect sizes were found across all subdomains, none of which were found to be statistically significant. Results indicate that youth with OCD do not exhibit noteworthy neuropsychological deficits. This is in line with recent suggestions that OCD may not be characterized by clinically meaningful neuropsychological impairments. However, the small number of available controlled studies highlights the urgent need for more neuropsychological research in this population, as well as for further exploration of the neurodevelopmental hypothesis in pediatric OCD. Finally, the relatively low persistence rates of OCD into adulthood should be taken under consideration, especially in the context of the putative neuropsychological performance differences between adult and pediatric OCD populations. © 2015 Association for Child and Adolescent Mental Health.

    Full Text Available OBJECTIVES: To investigate feasibility and easiness of administration of a brief and simple instrument addressing impairment associated with adult attention deficit hyperactivity disorder (ADHD and if ADHD subtypes were correlated to specific profiles of self-reported impairment. METHODS: Thirty-five adults (19 men and 16 women; mean age of 31.74 years diagnosed with ADHD according to DSM-IV with a semi-structured interview (K-SADS PL were asked to fill out a Likert scale covering six different functional areas (academic, professional, marital, familiar, social and daily activities. Clinicians questioned patients about their understanding of the questionnaire and investigated their answers in more details to check consistency of their answers. RESULTS: No patient reported difficulties in understanding the questionnaire. Further questioning of patients' answers confirmed their choices in the six areas. Academic burden had the highest average score in the whole sample, followed by professional burden. Social area had the lowest average score in this sample.

  18. Internet addiction and self-evaluated attention-deficit hyperactivity disorder traits among Japanese college students. (United States)

    Tateno, Masaru; Teo, Alan R; Shirasaka, Tomohiro; Tayama, Masaya; Watabe, Motoki; Kato, Takahiro A


    Internet addiction (IA), also referred to as Internet use disorder, is a serious problem all over the world, especially in Asian countries. Severe IA in students may be linked to academic failure, attention-deficit hyperactivity disorder (ADHD), and forms of social withdrawal, such as hikikomori. In this study, we performed a survey to investigate the relation between IA and ADHD symptoms among college students. Severity of IA and ADHD traits was assessed by self-report scales. Subjects were 403 college students (response rate 78%) who completed a questionnaire including Young's Internet Addiction Test (IAT) and the Adult ADHD Self-Report Scale-V1.1. Out of 403 subjects, 165 were male. The mean age was 18.4 ± 1.2 years, and mean total IAT score was 45.2 ± 12.6. One hundred forty-eight respondents (36.7%) were average Internet users (IAT Students with a positive ADHD screen scored significantly higher on the IAT than those negative for ADHD screen (50.2 ± 12.9 vs 43.3 ± 12.0). Our results suggest that Internet misuse may be related to ADHD traits among Japanese youth. Further investigation of the links between IA and ADHD is warranted. © 2016 The Authors.

    Full Text Available Few long-term studies have yet described neuropsychological outcome in preterm twins. Our aim was to assess, by long-term evaluation, neuropsychological outcome in preterm twins in order to define a correct follow-up program. Our study was a cohort one, with an index and a comparison group. Neonatal medical records of all preterm newborns admitted to our centre between 1991 and 1997 were reviewed and selected patients were recalled. The sample population included two matched groups of children aged 6—12 years, 86 twins and 86 singletons, submitted to paediatric, neurological, psychological, and ophthalmological examinations. Inclusion criteria were twin pregnancy and gestational age 27—36 weeks for index group; same gestational age, but single pregnancy, for the comparison group. All children underwent paediatric and neuropsychiatric examinations, cognitive assessment, and psychological evaluation by standardized tests for screening of learning specific disorders and language difficulties, and finally, ophthalmological examination. In order to study their role in predicting neuropsychological outcome, we examined some perinatal prognostic factors by statistical analysis. Unfavourable neuropsychological outcome was observed in 55/172 (32% children, with different prevalence in the two groups, 42/172 (24% in twins and 13/172 (8% in singletons. Statistical analysis performed for examined prognostic factors showed significant differences in neuropsychological outcome with regard only to gestational age < 32 weeks, low birth weight, intraventricular haemorrhage, and periventricular leukomalacia. The incidence of neuropsychological diseases in the two groups showed significant difference about language and learning difficulties. Our data suggest that preterm twins represent a particular high-risk category of premature babies, mostly regarding the risk of so-called “minimal brain dysfunction”, so a careful follow-up is recommended.

  20. Neuropsychological predictors of dementia in late-life major depressive disorder. (United States)

    Potter, Guy G; Wagner, H Ryan; Burke, James R; Plassman, Brenda L; Welsh-Bohmer, Kathleen A; Steffens, David C


    Major depressive disorder is a likely risk factor for dementia, but some cases of major depressive disorder in older adults may actually represent a prodrome of this condition. The purpose of this study was to use neuropsychological test scores to predict conversion to dementia in a sample of depressed older adults diagnosed as nondemented at the time of neuropsychological testing. Longitudinal, with mean follow-up of 5.45 years. Outpatient depression treatment study at Duke University. Thirty nondemented individuals depressed at the time of neuropsychological testing and later diagnosed with incident dementia; 149 nondemented individuals depressed at the time of neuropsychological testing and a diagnosis of cognitively normal. All participants received clinical assessment of depression, were assessed to rule out prevalent dementia at the time of study enrollment, completed neuropsychological testing at the time of study enrollment, and were diagnosed for cognitive disorders on an annual basis. Nondemented, acutely depressed older adults who converted to dementia during the study period exhibited broadly lower cognitive performances at baseline than acutely depressed individuals who remained cognitively normal. Discriminant function analysis indicated that 2 neuropsychological tests, Recognition Memory (from the Consortium to Establish a Registry for Alzheimer's Disease neuropsychological battery) and Trail Making B, best predicted dementia conversion. Depressed older adults with cognitive deficits in the domains of memory and executive functions during acute depression are at higher risk for developing dementia. Some cases of late-life depression may reflect a prodrome of dementia in which clinical manifestation of mood changes may co-occur with emerging cognitive deficits.

    Previous neuropsychological studies indicate that OCD subtypes such as checking rituals might be associated with a working memory deficit. On the other hand, functional neuroimaging studies found functional abnormalities of the frontal cortex and subcortical structures in OCD. Combined with functional imaging method, we applied neuropsychological batteries to demonstrate a working memory deficit in OCD by comparison with normal controls. In addition, working memory and brain activation were further examined with symptom-based analysis. Forty patients with OCD and 25 normal controls were examined using neuropsychological tests including the WAIS-R, WCST, WMS-R, and R-OCFT and functional MRI (fMRI) during the N-back task including 0- and 2-back task. On fMRI, the brain regions activated during the performance and the differences in the activation between patients and controls were identified. Additional analyses of severity and subtypes were conducted by using Y-BOCS severity score, symptom-checklist and Leckman's four-factor model, respectively. On the neuropsychological tests, the OCD patients had significantly lower scores on the delayed recall section of the WMS-R and the immediate recall section of the R-OCFT compared to the controls. On fMRI, the patients showed greater activation in the right dorsolateral prefrontal cortex (DLPFC), left superior temporal gyrus (STG), left insula, and cuneus during two-back task compared to the controls. Right orbitofrontal cortex activity showed a significant positive correlation with Y-BOCS scores in OCD. Furthermore, patients with obsessions/checking rituals (n=10) showed severer memory deficits and decreased activity in the postcentral gyrus than patients with cleanliness/washing rituals (n=14). In conclusion, we found neuropsychological dysfunction and brain abnormalities in OCD. Furthermore, our results suggested that symptom severity and symptom subtype such as obsessions/checking might affect neuropsychological

    Reinhardt, D; Thiele, C; Creutzig, U


    In study AML-BFM 87 the relapse rate was lower in patients receiving cranial irradiation (CRT). However, CRT has always been associated with adverse cognitive side effects. Therefore, the impact of CRT on neuropsychological function in children with AML was retrospectively evaluated. We tested 53 children (30 boys, 23 girls) treated according to the AML-BFM-87 protocol (median age at diagnosis: 8.5 years, range 0.3 - 17.5; median time since diagnosis: 5.7 yrs, 3.8 - 10.7 yrs). To avoid any bias from additional therapy elements, patients with relapse or initial CNS involvement and transplanted patients were excluded (n=32). Our cohort was representative of the total group of 104 long term survivors of study AML-BFM 87. CNS prophylaxis consisted of ARA-C, high dose ARA-C i. v. and either no CRT (n=15) or CRT (n=38) at a dose of 12 - 18 Gy depending on age. Neuropsychological function was evaluated by psychological tests of attention and concentration (test d2 by Brickenkamp) and an intelligence test (Progressive Matrices by Raven). In addition, patients and their parents were interviewed about the occurrence of learning problems, subjective deficits in concentration and physical impairment. In the total group, no significant differences were seen between irradiated and non-irradiated patients regarding the psychological tests. However, the irradiated patients scored below the non-irradiated control group in test "d2" (concentration: 41st vs. 59th percentile). In the interview, irradiated patients tended to report more learning problems (lp) (10/36 vs. 1/14; p=0.15) and subjective deficits in concentration (con). In irradiated girls (con: 6/15 vs. 0/8; p=0.06; lp: 5/15 vs. 0/8; p=0.12) and younger patients (0 - 5 years at diagnosis; con: 7/12 vs. 2/9; p=0.18; lp 3/10 vs. 1/9; p=0.18) this trend was even more pronounced. Children with AML and CRT had no significant intellectual impairment in standardized tests when compared to non-irradiated patients. However

  4. [The neuropsychology of epilepsy: what factors are involved?]. (United States)

    Campos-Castello, J


    The epileptic child is three times more likely to have cognitive problems from other neurological pathologies, depending on three facts: the effect exerted by the epilepsy itself, any associated previously-existing neuropsychosocial deficits, and the side effects of the antiepileptic drug (AED). A certain degree of deterioration is universally accepted, although the factors involved in its production are not specified, but are generally accepted as being due to multiple causes. We analyse the relation between neuropsychology and epilepsy in neuropaediatrics. The relation between epilepsy and behaviour must be seen as the exception rather than the rule, unless there are co-existing personality disorders and/or mental deficiency. The cognitive effects of AED depend on the drug, on the dosages employed and the polypharmacy, and these effects can be both adverse and favourable. The differences observed between one drug and another are open to criticism, although monitored administration of suitable doses generally produces moderate adverse side effects, as evaluated using reliable appraisal methods (MIDDRA). Scaling time in the introduction of the drug is important, especially with some new AED. The mechanisms governing production vary, but an understanding of the mechanism of action improves cognitive functioning thanks to the control over the seizures. In infancy, idiopathic cognitive reactions are produced. The main disorders are a diminished reaction and information processing time with alterations affecting memory, attention and language. Epilepsy is associated to a number of different, generally moderate, cognitive problems. The age of onset, the type of syndrome, its aetiology, the response to treatment and polypharmacy are multifactorial elements conditioning the side effects. There is a need for batteries of tests capable of forecasting the future and controlling the progression of cognition during treatment. The side effects of AED affecting cognition and

  5. Neuropsychological correlates of decision making in patients with bulimia nervosa. (United States)

    Brand, Matthias; Franke-Sievert, Christiane; Jacoby, Georg E; Markowitsch, Hans J; Tuschen-Caffier, Brunna


    In addition to the core psychopathology of bulimia nervosa (BN), patients with BN often show impulsive behavior that has been related to decision making deficits in other patient groups, such as individuals with anorexia nervosa and pathological gamblers. However, it remains unclear whether BN patients also show difficulties in decision making. In this study, 14 patients with BN and 14 healthy comparison subjects, matched for age, gender, education, body mass index, and intelligence, were examined with the Game of Dice Task (M. Brand, E. Fujiwara, et al., 2005), a gambling task that has fixed winning probabilities and explicit rules for gains and losses, as well as with a neuropsychological test battery and personality questionnaires. On the task, the patients with BN chose the disadvantageous alternatives more frequently than did the comparison subjects. Performance on the Game of Dice Task was related to executive functioning but not to other neuropsychological functions, personality, or disease-specific variables in the BN group. Thus, in patients with BN, decision making abnormalities and executive reductions can be demonstrated and might be neuropsychological correlates of the patients' dysfunctional everyday-life decision making behavior. Neurocognitive functions should be considered in the treatment of BN. PsycINFO Database Record (c) 2007 APA, all rights reserved.

  6. Neuropsychological profile in patients with schizotypal personality disorder or schizophrenia. (United States)

    Matsui, Mié; Sumiyoshi, Tomiki; Kato, Kanade; Yoneyama, Eiichi; Kurachi, Masayoshi


    Neuropsychological impairments have been consistently reported in patients with schizophrenia. As little is known whether subjects with schizotypal personality disorder exhibit neurocognitive dysfunction similar to that in schizophrenia, we assessed the neuropsychological profile of 15 subjects with schizotypal personality disorder and compared it with that for 15 patients with schizophrenia and for 15 psychiatrically normal volunteers. All participants were administered a standard neuropsychological battery assessing language ability, spatial ability, visuomotor function, verbal memory, visual memory, auditory attention, visual attention, and executive function. Performance on most of the cognitive domains was impaired in patients with schizotypal personality disorder but less than patients with schizophrenia. Specifically, impairment in verbal memory and visuomotor ability in patients with schizotypal personality disorder and patients with schizophrenia were comparable, while patients with schizophrenia performed worse on the test of executive function than did patients with schizotypal personality disorder. As a whole, cognitive deficits in patients with schizotypal personality disorder were qualitatively similar to, but quantitatively milder than, those for patients with schizophrenia. The results suggest that cognitive abilities related to frontotemporal lobe function are disturbed across these schizophrenia-spectrum disorders.

  7. Evaluating Sleep Disorders amongst Children with Attention Deficit/ Hyperactivity Disorder (ADHD

    Directory of Open Access Journals (Sweden)

    Khalil Esmaeilpour


    Full Text Available Background: The attention deficit/ hyperactivity disorder (ADHD is one of the most compromising mental disorders of childhood and adolescence. Subsequently, different studies in recent years were conducted on the relationship between sleep disturbances and ADHD in children. About 30% of children and 60% to 80% of adults with ADHD develop sleep disorders, which may result in cognitive and behavioral changes in the patients. The current study aimed at comparing sleep disorders in children with ADHD and their normal peers in Tabriz, Iran. Materials and Methods: The current case-control study was conducted on the target population of children within the age range of 6 to 12 years, which included 50 children with ADHD receiving medication, 55 children with ADHD symptoms without receiving any medication, and 71 normal children, all of which screened from the school students of Tabriz using the child symptom inventory-4 (CSI-4 and selected by the multi-stage cluster sampling method. The children's sleep habits questionnaire (CSHQ was completed by their mothers and data were analyzed using the multivariate analysis of variance (MANOVA. Results: According to the results of the current study, a significant number of children with ADHD showed sleep disorder that can accounts for some degree of their behavioral dysregulation. There was a significant difference among the study groups regarding the subscales of sleep resistance and sleep duration, daytime sleep, parasomnia,  and sleep apnea (p 0.05. Conclusion: Since children with ADHD usually have more sleep problems, considering the sleep quality in such children is of great importance; in the treatment of such children their sleep problems should be considered particularly.

  8. The neuropsychological correlates of borderline personality disorder and suicidal behaviour. (United States)

    LeGris, Jeannette; van Reekum, Rob


    In subjects with borderline personality disorder (BPD), compared with subjects who attempted suicide, to review neuropsychological (NP) function that may predispose to suicidal behaviour along a continuum of high and low lethality. We undertook electronic searches of MEDLINE, PsycINFO, EMBASE, Biosos Reviews, and Cinhal. The searches were restricted to English-language publications from 1985 onward. The search terms borderline personality disorder, suicide, suicide attempt, self-harm behaviour, neuropsychological, executive function (EF), neurocognitive, and neuropsychological function produced 29 neuropsychology studies involving BPD and 7 neuropsychology studies of suicide attempters, regardless of psychiatric diagnosis. Of the BPD studies, 83% found NP impairment in one or more cognitive domains, irrespective of depression, involving specific or generalized deficits linked to the dorsolateral prefrontal and orbitofrontal regions. The functions most frequently reported (in 71% to 86% of BPD studies) are response-inhibitory processes affecting executive function performance that requires speeded attention and visuomotor skills. Decision making and visual memory impairment are also most frequently affected; 60% to 67% of BPD studies report attentional impairment, verbal memory impairment, and visuospatial organizational impairment. Least affected processes in BPD appear to involve spatial working memory, planning, and possibly, IQ. The similarities in NP deficits found in BPD and suicide-attempt studies involve decision making and Trails performances. BPD studies, however, reflect more frequent impairment on the Stroop Test and Wisconsin Card Sort Test performance than the suicide-attempt studies, whereas verbal fluency appears to be more frequently impaired in those attempting suicide. Impaired EF and disinhibitory processes, as indicated by verbal fluency, Trails, and Stroop performance, primarily associated with dorsolateral prefrontal cortical regions may

  9. Proposition of a protocol to evaluate upper-extremity functional deficits and compensation mechanisms: application to elbow contracture. (United States)

    Fradet, Laetitia; Liefhold, Beate; Rettig, Oliver; Bruckner, Thomas; Akbar, Michael; Wolf, Sebastian I


    Instrumented gait analysis is widely accepted as an objective assessment of lower-extremity function. Conversely, upper-extremity function suffers from lack of objective evaluation. The present paper aims at proposing a protocol to be used to clinically and objectively evaluate upper-extremity function whatever the pathological joint. Secondly, it aims at better understanding the consequences on upper-extremity function and the compensation mechanisms induced by elbow contracture. Elbow contracture was simulated in this study by using a brace. Twelve healthy subjects followed an instrumented 3D movement analysis while performing 11 daily life movements. The movements were performed with 3 different elbow contracture conditions, simulated by wearing an adjustable elbow brace. The proposed protocol was successful in creating a wide range of motion at all the upper-extremity joints. The activity-related range of motion and the mean range of motion computed on the whole set of daily life movements were effective in evaluating the severity of elbow contracture. The lack of elbow flexion was compensated by trunk flexion, hand flexion and radial deviation, and combined movement of shoulder flexion, abduction, and humeral internal rotation. Deficit in elbow extension was mainly compensated by the use of trunk flexion. A protocol could be proposed for the objective evaluation of upper-extremity function. Its application to elbow contracture suggests that loss of elbow flexion affects more movements than loss of elbow extension.

  10. Postoperative neuropsychological change and its underlying mechanism in patients undergoing coronary artery bypass grafting. (United States)

    Yin, Yi-qing; Luo, Ai-lun; Guo, Xiang-yang; Li, Li-huan; Huang, Yu-guang


    The high incidence of neuropsychologic deficits after cardiac surgery, including cognitive dysfunction and mood status, has significantly influenced the prognosis, outcome of treatment and long-term quality of life of patients. With a circadian secretion pattern, melatonin and cortisol are capable of modulating the human physiological processes and neuropsychological status, whereas disorder of their secretion pattern may lead to many diseases. However, it is unclear whether neuroendocrine variations are related to the neuropsychologic status in patients undergoing coronary artery bypass grafting (CABG). Forty male patients scheduled for CABG with hypothermic cardiopulmonary bypass (CPB) (n = 20) or off-pump coronary artery bypass (OPCAB) (n = 20) were studied. Blood samples were taken intraoperatively at specific time-points and every 3 hours within the first postoperative 24 hours to determine plasma concentrations of melatonin and cortisol. A neuropsychologic test battery including depression and anxiety was administered preoperatively and 7 to 10 days postoperatively. Statistical methods included the nonparametric analysis, multiple linear regression and cosinor analysis. The patients in the CPB group exhibited more severe neuropsychologic deficits and more anxious than those in the OPCAB group after surgery. In both groups, patients were more depressed postoperatively than preoperatively and recovered 3 months after surgery. Depression and anxiety were correlated with some factors of cognitive dysfunctions. In the postoperative 24 hours, 2 patients in the CPB group, and 6 patients in the OPCAB group showed a circadian rhythm of melatonin secretion. As for cortisol secretion, there were 3 patients in the CPB group and 7 in the OPCAB group respectively. Parameters of circadian rhythm of melatonin in the CPB group and those of secretion rhythm of cortisol in both groups were correlated with depression and some neuropsychologic tests. The incidence of

  11. Williams syndrome: a neuropsychological profile. (United States)

    MacDonald, G W; Roy, D L


    Seven children with Williams syndrome were seen for neuropsychological assessment. Their performances were compared with those obtained from a clinical control group matched for age, sex, and Peabody Picture Vocabulary Test Standard Score. The results support the view that children with Williams syndrome suffer from a severe impairment in visual-motor integration. No child in the Experimental Group outperformed his/her matched control on either subtest assessing visual-motor integration skills, while no significant differences were noted between the groups on tests for simple motor skills (e.g., finger oscillation). Significant differences were also found on the subtests of the Wide Range Achievement Test. No significant differences between the groups were noted on tests for general language skills. The remedial educational, and neuropsychological implications of these findings are discussed.

  12. Neuropsychological Decline in Schizophrenia from the Premorbid to Post-Onset Period: Evidence from a Population-Representative Longitudinal Study (United States)

    Meier, Madeline H.; Caspi, Avshalom; Reichenberg, Abraham; Keefe, Richard S.E.; Fisher, Helen; Harrington, HonaLee; Houts, Renate; Poulton, Richie; Moffitt, Terrie


    Objective Despite widespread belief that neuropsychological decline is a cardinal feature of the progression from the premorbid to the chronic form of schizophrenia, few longitudinal studies have examined change in neuropsychological functioning from before to after the onset of schizophrenia. We addressed the following unresolved questions: Is neuropsychological decline generalized versus confined to particular mental functions? Is neuropsychological decline unique to schizophrenia? Do individuals with schizophrenia also have cognitive problems in everyday life? Method Participants were members of a representative cohort of 1,037 individuals born in Dunedin, New Zealand between 1972-73 and followed prospectively to age 38, with 95% retention. Assessment of IQ and other specific neuropsychological functions was conducted at ages 7-13, before the onset of schizophrenia, and again at age 38. Informants also reported on cognitive problems at age 38. Results Individuals with schizophrenia showed decline in IQ as well as a range of different mental functions, particularly those tapping processing speed, learning, executive functioning, and motor functioning. There was little evidence of decline in verbal abilities or delayed memory, however, and the developmental progression of deficits in schizophrenia differed across mental functions. Processing speed deficits increased gradually from childhood to beyond the early teen years, whereas verbal deficits emerged early but remained static through midlife. Neuropsychological decline was specific to schizophrenia, as no evidence of decline was apparent among individuals with persistent depression, children with mild cognitive impairment, individuals matched on childhood risk factors for schizophrenia, and psychiatrically healthy individuals. Informants also reported cognitive problems for individuals diagnosed with schizophrenia. Conclusion There is substantial neuropsychological decline in schizophrenia from the premorbid to

  13. Neuropsychological functioning, age, and medication adherence in bipolar disorder (United States)

    Raust, Aurélie; Etain, Bruno; Guillot, Romain; Job, Sophie; Loftus, Joséphine; Médecin, Isabelle; Bougerol, Thierry; Polosan, Mircea; Fredembach, Benjamin; Gard, Sébastien; M’Bailara, Katia; Kahn, Jean-Pierre; Roux, Paul; Homassel, Anne-Sophie; Carminati, Mathilde; Matos, Lucile; Olié, Emilie; Bellivier, Frank; Courtet, Philippe; Henry, Chantal; Leboyer, Marion; Azorin, Jean-Michel; Belzeaux, Raoul


    Objectives Poor adherence to medication is frequent in bipolar disorder (BD) and has been associated with several factors. To date, the relationship between low adherence and neuropsychological functioning in BD is still unclear. As age and neuropsychological functioning might have opposing influences on adherence, our aim was to investigate this link with a particular focus on the effect of age. Methods In a cross-sectional study, we included 353 patients divided into two age-groups (16–46; 47–71) from a French cohort diagnosed with BD (type I, II, NOS) and strictly euthymic. All patients had a standardized clinical and neuropsychological assessment and were categorized as high (n = 186) or low (n = 167) adherent based on their score from the Medication Adherence Rating Scale. Clinical information was collected based on a standardized interview and clinical validated scales. Neuropsychological performances were evaluated with an established standardized neuropsychological battery for bipolar disorder patients. After univariate analysis, neuropsychological and clinical predictors of low adherence were included in two age-specific stepwise multiple logistic regressions. Results A smaller number of hospitalizations (OR = 0.846, p = 0.012), a shorter illness duration (OR = 0.937, p = 0.003) and higher adverse effects (OR = 1.082, p<0.001) were associated with a greater risk of low adherence in the younger patients. In the older patients, low adherence was also predicted by a smaller number of hospitalizations (OR = 0.727, p = 0.008) and higher adverse effects (OR = 1.124, p = 0.005). Interestingly poor inhibition performance was also a significant predictor of low adherence in older patients (OR = 0.924, p = 0.030). Conclusions We found an age-specific relationship between cognitive functioning and adherence in patients with BD. Poor inhibition performances predicted low adherence in older patients only. Our results highlight the need to provide age

    Vasterling, Jennifer J; Proctor, Susan P; Amoroso, Paul; Kane, Robert; Heeren, Timothy; White, Roberta F


    The effects of war-zone deployment on neuropsychological health remain poorly understood. Neuropsychological performance deficits serve as sensitive measures of neural dysfunction and are often associated with psychosocial and occupational problems. Previous studies have not conducted objective neuropsychological assessments both before and after a major war-zone deployment. To examine objective neuropsychological outcomes of Iraq War deployment in a large military cohort. The Neurocognition Deployment Health Study, a prospective, cohort-controlled study conducted at military installations. This report centers on 961 male and female active-duty Army soldiers drawn from the larger cohort. Deploying Army soldiers (n = 654) were examined prior to deployment to Iraq (April-December 2003) and shortly after return (within a mean of 73 days [median, 75 days]; January-May 2005) from Iraq deployment. A comparison group of soldiers (n = 307) similar in military characteristics but not deploying overseas during the study was assessed in sessions timed to be as close as possible to the assessment of deployers. Military unit sampling procedures facilitated representation of combat, combat support, and combat service support functions among both deployers and nondeployers. Individually administered, performance-based neuropsychological tasks. Estimates (beta; the unstandardized parameter estimate) for the absolute differences in adjusted mean outcome scores between deployed and nondeployed groups were determined using generalized estimating equations. Multiple linear regression analyses adjusted for battalion membership revealed that Iraq deployment, compared with nondeployment, was associated with neuropsychological compromise on tasks of sustained attention (beta = 0.11; PIraq deployment was also associated with increased negative state affect on measures of confusion (beta = 1.40; PIraq is associated with increased risk of neuropsychological compromise. Findings point to the

    Weyandt, Lisa L; Oster, Danielle R; Gudmundsdottir, Bergljot Gyda; DuPaul, George J; Anastopoulos, Arthur D


    Increasing numbers of students with attention-deficit/hyperactivity disorder (ADHD) are attending college; however, little empirical information is available concerning the functional impairment experienced by these students. Although preliminary studies suggest that college students with ADHD are more likely to experience a variety of psychosocial and academic difficulties compared to their peers without the disorder, findings regarding neuropsychological functioning have been inconsistent with some studies reporting that college students with ADHD perform more poorly on various cognitive and neuropsychological tasks while others report no differences compared to their peers without ADHD. The purposes of the present study, the Trajectories Related to ADHD in College project, a longitudinal study following the 4-year outcomes of college students with and without ADHD, were to (a) examine the performance of 436 first-year college students with and without ADHD (51.6% female) on measures of executive function (EF) and intelligence and (b) investigate the association of self-reported use of stimulant medication and neuropsychological performance in students with ADHD. Participant data from their first year of involvement in the study were analyzed. Participants with ADHD performed more poorly on task-based and self-report EF measures relative to the comparison group. In contrast, no significant group differences were found with respect to intellectual performance. Within the ADHD group, use of prescription stimulant medication was associated with improved performance on some, but not all, neuropsychological tasks. Additional analyses also revealed significant group differences in EF based on clinical diagnostic status. College students with ADHD demonstrated poorer EF than their peers without ADHD and psychostimulant medication was associated with improved EF performance. No group differences were found with respect to intellectual functioning, Lastly, having one or

    Practical experience is central to the education and training of neuropsychologists, beginning in graduate school and extending through postdoctoral fellowship. However, historically, little attention has been given to the structure and requirements of practicum training in clinical neuropsychology. A working group of senior-level neuropsychologists, as well as a current postdoctoral fellow, all from a diverse range of settings (The AACN Practicum Guidelines Workgroup), was formed to propose guidelines for practicum training in clinical neuropsychology. The Workgroup reviewed relevant literature and sought input from professional organizations involved in education and training in neuropsychology. The proposed guidelines provide a definition of practicum training in clinical neuropsychology, detail entry and exit criteria across competencies relevant to practicum training in clinical neuropsychology, and discuss the relationship between doctoral training programs and practicum training sites. The proposed guidelines also provide a methodology for competency-based evaluation of clinical neuropsychology practicum trainees and outline characteristics and features that are integral to an effective training environment. Although the guidelines discussed below may not be implemented in their entirety across all clinical neuropsychology practicum training sites, they are consistent with the latest developments in competency-based education.

  17. Neuropsychological outcomes in children of mothers with epilepsy. (United States)

    Kantola-Sorsa, Elisa; Gaily, Eija; Isoaho, Mirva; Korkman, Marit


    The study investigated the nature of the effects of maternal epilepsy on cognitive performance of the offspring. One hundred fifty-four children of mothers with epilepsy aged 5 to 11 years (study group), along with 130 control children, comparable with respect to IQ, socio-economic status, age, and gender underwent a neuropsychological assessment using subtests from the NEPSY: A Developmental Neuropsychological Assessment, tapping attentional, auditory-verbal, visuomotor, fine motor, and memory abilities. The study group scored significantly lower than the controls on measures of attention, memory, and fine-motor function. Deficits were more marked in but not limited to the subset of the study group exposed to maternal medication in utero. Group differences on auditory attention were found only in younger children. Valproate-exposed children obtained lower scores on sentence repetition, as well as on the more demanding part of a test of auditory attention, than other children in the study group, suggesting weaknesses in working memory in the former subgroup. Confounding by maternal epilepsy type and polytherapy complicate interpretation of this finding. Differences between subsets of children not exposed to anti-epileptic drugs in utero and controls suggest that both drug exposure and genetic factors may contribute to cognitive deficits associated with maternal epilepsy.

    Amer Cavalheiro Hamdan; Ana Paula Almeida de Pereira; Tatiana Izabele Jaworski de Sá Riechi


    The present paper aimed to briefly present a historical view of Neuropsychology and later, to propose research topics in Brazil. Neuropsychology history encompassed at least three major themes: the cardiac hypothesis versus the brain hypothesis, localizationism versus holism and functionalism versus cognitivism. These themes influenced research in neuropsychology and based current practice. Furthermore, two important aspects of neuropsychology are discussed: neuropsychological assessment in d...

  19. Neurological and neuropsychological functions in adults with a history of developmental arsenic poisoning from contaminated milk powder. (United States)

    Yorifuji, Takashi; Kato, Tsuguhiko; Ohta, Hitoshi; Bellinger, David C; Matsuoka, Kenichi; Grandjean, Philippe


    During the summer of 1955, mass arsenic poisoning of bottle-fed infants occurred in the western part of Japan due to contaminated milk powder, and more than 100 died; some childhood victims were later found to suffer from neurological sequelae in adolescence. This unique incident enabled us to explore infancy as a critical period of arsenic exposure in regard to developmental neurotoxicity and its possible persistence through adulthood. The purpose of this work is to evaluate the association between developmental arsenic exposure and the neurological outcomes more than 50 years later. We conducted a retrospective cohort study during the period from April 2012 to February 2013 in two hospitals in Okayama Prefecture, Japan. The study sample consisted of 50 individuals: 27 known poisoning victims from Okayama Prefecture, and 23 non-exposed local controls of similar age. In addition to neurological examination, we adapted a battery of neurophysiological and neuropsychological tests to identify the types of brain functions affected by early-life arsenic exposure. While limited abnormalities were found in the neurophysiological tests, neuropsychological deficits were observed. Except for Finger tapping, all test scores in the exposed group--Vocabulary and Block Design from Wechsler Adults Intelligent Scale III, Design memory subtest from Wide Range Assessment of Memory and Learning 2, and Grooved pegboard test--were substantially below those obtained by the unexposed. The exposed group showed average performance at least 1.2 standard deviations below the average for the controls. Exposed participants performed less well than controls, even after exclusion of subjects with recognized disabilities or those with a high level of education. Adults who had suffered arsenic poisoning during infancy revealed neuropsychological dysfunctions, even among those subjects not recognized as having disabilities. Developmental neurotoxicity due to arsenic likely results in permanent

    This article reviews the history of neuropsychology applied towork with children. Several authors have advocated for the application of neuropsychology to the school centres, a specialty some have called “school neuropsycology”. Since the term was initially introduced (Hynd & Obrzut, 1981), considerable advances have arisen regarding the field and professional identityof this specialty. Luria’work continues to have a strong international influence. Luria has served for neuropsychological unde...

  1. Pregnancy complications and neuropsychological outcomes: A review. (United States)

    Gerner, Gwendolyn; Baron, Ida Sue


    Pregnancy complications elevate risk of associated adverse medical, socioenvironmental, and behavioral outcomes in children. These are likely to have a substantial impact on neuropsychological functioning and mental health across the child's lifespan. Thus, an understanding of the complex relationships between pregnancy complications and neuropsychological outcomes is critical for both practitioners and researchers. This review summarizes prevalent pregnancy complications and the associated psychological and neuropsychological findings, highlighting methodological challenges that have restricted investigations of these outcomes and identifying opportune areas for future study.

    Terlizzi, Rossana; Calandra-Buonaura, Giovanna; Zanigni, Stefano; Barletta, Giorgio; Capellari, Sabina; Guaraldi, Pietro; Donadio, Vincenzo; Cason, Ernesto; Contin, Manuela; Poda, Roberto; Tonon, Caterina; Sambati, Luisa; Gallassi, Roberto; Liguori, Rocco; Lodi, Raffaele; Cortelli, Pietro


    Adult-onset autosomal dominant leukodystrophy (ADLD) is a rare progressive neurological disorder caused by Lamin B1 duplication (LMNB1). Our aim was to investigate longitudinally the pattern of the autonomic dysfunction and the degree of neuropsychological involvement. Three related ADLD patients and one asymptomatic carrier of LMNB1 duplication underwent a standardized evaluation of autonomic nervous system, including cardiovascular reflexes, pharmacological testing, microneurography, skin biopsy, Metaiodobenzylguanidine scintigraphy and a complete neuropsychological battery. An early neurogenic orthostatic hypotension was detected in all patients and confirmed by a low rise in noradrenaline levels on Tilt Test. However infusion of noradrenaline resulted in normal blood pressure rise as well as the infusion of clonidine. At the insulin tolerance test the increase in adrenaline resulted pathological in two out three patients. Microneurography failed to detect muscle sympathetic nerve activity bursts. Skin biopsy revealed a poor adrenergic innervation, while cardiac sympathetic nerves were normal. None of ADLD patients showed a global cognitive deficit but a selective impairment in the executive functions. Autonomic disorder in ADLD involves selectively the postganglionic sympathetic system including the sympatho-adrenal response. Cognitive involvement consisting in an early impairment of executive tasks that might precede brain MR abnormalities. Copyright © 2016 Elsevier B.V. All rights reserved.

  4. [Procedural learning disorder: neuropsychological characteristics]. (United States)

    Crespo-Eguílaz, N; Narbona, J

    This research aims at neurocognitive delineation of the core features of procedural learning disorder (PLD), otherwise labeled as motor coordination disorder or non-verbal learning disorder. A sample of 209 correlative outpatients (73% males), aged 6-12 years, all of them having QI ranging from 81 to 120, was clustered into the following neurobehavioural groups: PLD (n = 16), PLD plus attention deficit hyperactivity disorder (ADHD) (n = 37), ADHD combined type (n = 47), ADHD predominantly inattentive type (n = 23), specific language impairment (n = 68), and semantic-pragmatic language impairment (n = 18). Two additional groups of patients were included for some comparisons: children with periventricular leukomalacia (PVL) without learning disability (n = 8) or associating PLD (n = 17). A set of behavioural scales and neurocognitive tests was used to evaluate verbal and non-verbal IQ, attention, impulsivity control, visuo-motor coordination, declarative memory, procedural memory and learning, formal and functional dimensions of language, peer relationships and academic achievement. Parametric analysis were used to test the differences and similarities of neurobehavioural variables between groups. Our results allow us to conclude that PLD implies a difficult acquisition of automatized motor, cognitive and communicative abilities required in school work and peer social relationships. PLD is different from autistic spectrum disorders. It is frequently associated to inattentive ADHD. Operational criteria for diagnosis of PLD are proposed, according to our results. A bilateral posterior parietal dysfunction is a plausible explanation of its physiopathology. Preserved general intelligence and formal linguistic abilities are the clues for intervention designs.

  5. The Neuropsychology (Broadly Conceived) of Multiple System Atrophy, Progressive Supranuclear Palsy, and Corticobasal Degeneration. (United States)

    Gerstenecker, Adam


    To review the cognitive and behavioral features of the different atypical parkinsonian syndromes in which motor symptoms dominate early clinical symptomology: multiple systems atrophy (MSA), progressive supranuclear palsy (PSP), and corticobasal degeneration (CBD). The impact of cognitive and behavioral deficits on quality of life, associations between neuropsychological and neuropsychiatric findings and brain imaging, and cognitive and behavioral symptom management are also discussed. A review of the available MSA, PSP, and CBD literature was conducted, with emphasis given to studies investigating the cognitive and behavioral features of the syndromes. Although the three reviewed atypical parkinsonian syndromes share many similarities to each other and PD from a neuropsychological perspective, differences in prevalence and severity of cognitive impairment and patterns of performance on neuropsychological and neuropsychiatric measures exist in the research literature. Cognitive and behavioral features are early and pervasive aspects of MSA, PSP, and CBD.

  6. Lifting the veil: how to use clinical neuropsychology to assess dementia. (United States)

    Burrell, James R; Piguet, Olivier


    Neurologists often struggle to interpret the results of neuropsychological testing, even though cognitive assessments are an integral component of the diagnostic process in dementia syndromes. This article reviews the principles underlying clinical neuropsychology, background on common neuropsychological tests, and tips on how to interpret the results when assessing patients with dementia. General cognitive screening tools, appropriate for use by general neurologists and psychiatrists, as well as specific cognitive tests examining the main cognitive domains (attention and orientation, memory, visuospatial function, language and executive function) in patients with dementia are considered. Finally, the pattern of deficits, helpful in defining clinical dementia phenotypes and sometimes in predicting the underlying molecular pathology, are outlined. Such clinicopathological associations will become invaluable as disease-modifying treatments for dementia are developed and implemented. Published by the BMJ Publishing Group Limited.

  7. Hypothesis-Driven Treatment of Naming Deficits. (United States)

    Robinson, K M; Grossman, M


    This article proposes to use information processing models of cognition to guide behaviorally based treatments of language deficits, specifically, single-word object naming. Our approach is illustrated with a clinical case of a transcortical sensory aphasic. Clinical neuropsychological and functional imaging data demonstrate that the components comprising the information processing network that underpins naming can be mapped onto a cerebral neural network in the neurologically intact and that reorganization of function seen in transcortical sensory aphasia can demonstrate plasticity in this neural network. The observed balance of impaired and preserved clinical and physiological components in reorganizing neural networks such as this can be used to design treatment strategies to alleviate naming deficits.

  9. Evidence-Based Indicators of Neuropsychological Change in the Individual Patient: Relevant Concepts and Methods (United States)

    Repeated assessments are a relatively common occurrence in clinical neuropsychology. The current paper will review some of the relevant concepts (e.g., reliability, practice effects, alternate forms) and methods (e.g., reliable change index, standardized based regression) that are used in repeated neuropsychological evaluations. The focus will be on the understanding and application of these concepts and methods in the evaluation of the individual patient through examples. Finally, some future directions for assessing change will be described. PMID:22382384

  10. Individual neuropsychological profiles at age 5½ years in children born preterm in relation to medical risk factors. (United States)

    Lundequist, Aiko; Böhm, Birgitta; Smedler, Ann-Charlotte


    Follow-up studies of preterm children have reported a range of cognitive deficits, particularly in executive functions, visuospatial abilities, and learning. However, few researchers have adopted a person-oriented approach, exploring individual neuropsychological profiles. The aim of this study was to identify typical neuropsychological profiles among preterm children and control children, respectively. A second aim was to investigate if neuropsychological profiles at age 5½ might be associated with perinatal medical risk factors. As part of the longitudinal Stockholm Neonatal Project, NEPSY for 4- to 7-year-old children ( Korkman, 1990 ), WPPSI-R, and Movement ABC were administered at age 5½ years to 145 preterm (mean gestational age 28 weeks) and 117 control children born at term. For the present study, the NEPSY results of each child were transformed into summary z scores for each of 5 neuropsychological domains: attention, memory, sensory-motor, verbal, and visuospatial functions. Subsequently, Ward's cluster analysis was performed for the preterm and control groups separately, identifying 5 neuropsychological profiles in both groups explaining around 56% and 57% of the variance, respectively. Overall, preterm children had lower neuropsychological results but also more diverging profiles compared to controls. The variability in outcome could not be sufficiently explained by birth weight, gestational age, or medical risks. The results suggest that prematurity interacts dynamically with genetic, medical, and environmental factors in neuropsychological development.

  11. Call for uniform neuropsychological assessment after aneurysmal subarachnoid hemorrhage: Swiss recommendations. (United States)

    Zweifel-Zehnder, Antoinette E; Stienen, Martin N; Chicherio, Christian; Studerus-Germann, Aline; Bläsi, Stefan; Rossi, Stefania; Gutbrod, Klemens; Schmid, Nicole; Beaud, Valérie; Mondadori, Christian; Brugger, Peter; Sacco, Leonardo; Müri, Rene; Hildebrandt, Gerhard; Fournier, Jean-Yves; Keller, Emanuela; Regli, Luca; Fandino, Javier; Mariani, Luigi; Raabe, Andreas; Daniel, Roy Thomas; Reinert, Michael; Robert, Thomas; Schatlo, Bawarjan; Bijlenga, Philippe; Schaller, Karl; Monsch, Andreas U


    In a high proportion of patients with favorable outcome after aneurysmal subarachnoid hemorrhage (aSAH), neuropsychological deficits, depression, anxiety, and fatigue are responsible for the inability to return to their regular premorbid life and pursue their professional careers. These problems often remain unrecognized, as no recommendations concerning a standardized comprehensive assessment have yet found entry into clinical routines. To establish a nationwide standard concerning a comprehensive assessment after aSAH, representatives of all neuropsychological and neurosurgical departments of those eight Swiss centers treating acute aSAH have agreed on a common protocol. In addition, a battery of questionnaires and neuropsychological tests was selected, optimally suited to the deficits found most prevalent in aSAH patients that was available in different languages and standardized. We propose a baseline inpatient neuropsychological screening using the Montreal Cognitive Assessment (MoCA) between days 14 and 28 after aSAH. In an outpatient setting at 3 and 12 months after bleeding, we recommend a neuropsychological examination, testing all relevant domains including attention, speed of information processing, executive functions, verbal and visual learning/memory, language, visuo-perceptual abilities, and premorbid intelligence. In addition, a detailed assessment capturing anxiety, depression, fatigue, symptoms of frontal lobe affection, and quality of life should be performed. This standardized neuropsychological assessment will lead to a more comprehensive assessment of the patient, facilitate the detection and subsequent treatment of previously unrecognized but relevant impairments, and help to determine the incidence, characteristics, modifiable risk factors, and the clinical course of these impairments after aSAH.

  12. [The evaluation of aphasic deficits for the definition of a targetted logotherapeutic treatment]. (United States)

    Bazzini, A; Pezzoni, F; Zonca, G; Guarnaschelli, C; Zelaschi, F; Luzzatti, C


    The Aachener Aphasie Test (AAT) is the major German test for the diagnosis of aphasic disorders. The test is easy to use and is valid and reliable for the diagnosis of aphasia and its severity and to evaluate the recovery of the aphasic disorder after language rehabilitation. The AAT is, however, not sufficient to define cognitively sound logotherapeutic treatment. The use of tasks which are based on cognitive functional models allows the identification of specific processing levels that have been damaged by a cerebral lesion, and the definition of a focussed rehabilitation plan. In this paper, we will discuss the results of a cognitive neurolinguistic treatment in a patient who suffered of Broca's aphasia with agrammatism and phonological dyslexia.

  13. Non-literal language deficits in mild cognitive impairment. (United States)

    Cardoso, Sandra; Silva, Dina; Maroco, João; de Mendonça, Alexandre; Guerreiro, Manuela


    Verbal language deteriorates in Alzheimer's disease, contributing to dramatic disturbances in the ability to communicate. The presence of language disturbances may be detected at earlier phases of the neurodegenerative process, like mild cognitive impairment (MCI). In daily verbal interactions, people mostly use literal language, but sometimes they employ non-literal language, which requires listeners to interpret messages beyond the plain meaning of the words and can be quite demanding. In the present study, we tested the hypotheses that patients with MCI may have deficits in non-literal language, and these deficits are more pronounced than deficits in literal language. Participants were recruited in a private memory clinic and senior universities. General cognitive evaluation included a comprehensive neuropsychological battery, the Mini-Mental State Examination, and the instrumental activities of daily living scale. Literal language was assessed with the semantic decision test, Token Test, and literal text comprehension test, and non-literal language with the proverbs comprehension, idiomatic expressions and non-literal text comprehension tests. Fifty-two participants with MCI and 31 controls were recruited. Patients with MCI had lower scores in all complex language tests, both literal (Token Test, semantic decision and literal text) and non-literal (proverbs, idiomatic expressions, and non-literal text), than the controls; the difference in literal text score was marginally significant. As much as 69% of MCI participants had deficits (performance below 1.5 SD of the mean) on at least one of the complex language tasks. Deficits were more frequent on the proverbs comprehension and semantic decision tests, and the deficits on these tests did not significantly differ from that on the Token Test. Patients with MCI are hindered in understanding complex language, both literal and non-literal. In daily living, these complex language deficits could compromise effective

  14. Murder and psychosis: Neuropsychological profiles of homicide offenders with schizophrenia. (United States)

    Stratton, John; Brook, Michael; Hanlon, Robert E


    Neurocognitive dysfunction, a core feature of schizophrenia, is thought to contribute to the impulsive violent aggression manifested by some individuals with schizophrenia, but not enough is known about how homicidal individuals with schizophrenia perform on neuropsychological measures. The primary aim of our study was to describe the neuropsychological profiles of homicide offenders with schizophrenia. Supplementary analyses compared the criminal, psychiatric and neuropsychological features of schizophrenic homicide offenders with and without God/Satan/demon-themed psychotic symptoms. Twenty-five men and women diagnosed with schizophrenia who had killed another person - 21 convicted of first-degree murder and 4 found not guilty by reason of insanity - completed neuropsychological testing during forensic evaluations. The sample was characterised by extensive neurocognitive impairments, involving executive dysfunction (60%), memory dysfunction (68%) and attentional dysfunction (50%), although those with God/Satan/demon-themed psychotic symptoms performed better than those with nonreligious psychotic content. Our findings indicate that impaired cognition may play an important role in the commission of homicide by individuals with schizophrenia. A subgroup with God/Satan/demon delusions seem sufficiently less impaired that they might be able to engage in metacognitive treatment approaches, aimed at changing their relationship to their psychotic symptoms, thus reducing the perception of power and omnipotence of hallucinated voices and increasing their safety.

  15. The Evaluation of Family Quality of Life of Children with Autism Spectrum Disorder and Attention Deficit Hyperactive Disorder

    Directory of Open Access Journals (Sweden)

    Roxana ŞIPOŞ


    Full Text Available The Quality of Life (QoL represents a dimension of the overall status and of the wellbeing that might be influenced by various factors. Researchers suggest that the parents of children with disabilities may be more vulnerable in developing physical or mental issues and that these families have a lower quality of life. Primary objective of the study was to evaluate the QoL of families with Autism Spectrum Disorder (ASD children as compared with that of families with Attention Deficit Hyperactive Disorder (ADHD children. The data were collected from 65 children with age ranging between 2 and 14 years, diagnosed with ASD and 49 children diagnosed with ADHD. The Family Quality of Life Survey (FQoL was used to evaluate the family QoL. The multidimensional model of quality of life explains 48% of the variance of the global evaluation of the family’s quality of life, proportion statistically significant (F (9, 103 = 12.71 p<0.01. Under statistical control of other factors the most important predictors remain family (beta = 0.43, p < 0.001, support from others (beta =- 0.26, p < 0.001, career (beta = 0.23, p < 0.001 and financial status (beta = 0.15, p = 0.04. Parents of children from the ADHD sample believe that family relationships are less important for the family quality of life, have fewer opportunities to improve these relations, a lower initiative which can derive also from the reduced importance they place on this domain.

  16. Neuropsychological performance in schizotypal personality disorder: evidence regarding diagnostic specificity. (United States)

    Mitropoulou, Vivian; Harvey, Phillip D; Maldari, Liza A; Moriarty, Patrick J; New, Antonia S; Silverman, Jeremy M; Siever, Larry J


    Individuals with schizotypal personality disorder (SPD) share cognitive deficits with schizophrenic patients, suggesting that these deficits represent a core feature of the schizophrenia spectrum. We investigated the neuropsychological profile in SPD patients compared with two comparison groups: healthy volunteers (HV) and patients who met criteria for another non-schizophrenia spectrum personality disorder (NSS). We tested 48 DSM-III-R SPD patients, 22 NSS and 32 HV on a neuropsychologic battery that included the California Verbal Learning Test (CVLT), Trail Making A and B, the DOT test of working memory, the Stroop Color-Word Interference, the Paced Auditory Serial Addition Test (PASAT), the Wechsler Memory Scale Visual Reproduction Test (WMSV-R), and the Wechsler Adult Intelligence Scale vocabulary and block design. Normative standards for performance were created using the HV group. SPD patients performed significantly worse compared with HVs; specifically, SPD patients demonstrated impaired performance on the PASAT and the WMSV-R immediate and delayed recall compared to HV. Moreover, SPD patients were impaired in the PASAT and the WMSV-R immediate condition compared with the NSS group. The NSS patients did not differ from HV on any of the cognitive tasks. The interpersonal factor of the schizotypal symptoms inversely correlated with the PASAT score (r = -.32, p impairment. These differences reached statistical significance for the PASAT (an auditory working memory task), and the WMSV-R immediate and delayed recall (a learning-recall test). In contrast, performance of NSS patients did not differ from that of HVs. The types of deficits observed in SPD patients are qualitatively similar to but milder than those seen in patients with schizophrenia.

  17. Evaluating potentials and corresponding risks of deficit irrigation systems: comparison of two stochastic optimization strategies (United States)

    Kloss, S.; Schütze, N.; de Paly, M.


    In this contribution, we introduce a stochastic framework for decision support for optimal planning and operation of water supply in irrigation. This consists of (i) a weather generator for simulating regional impacts of climate change on the basis of IPCC scenarios; (ii) a tailor-made evolutionary optimization algorithm for optimal irrigation scheduling with limited water supply; (iii) a mechanistic model for simulating water transport and crop growth in a sound manner; and (iv) a kernel density estimator for estimating stochastic productivity, profit and demand functions by a nonparametric method. As a result of several Monte Carlo simulation-optimization runs within the framework, we present stochastic crop-water production functions (SCWPF) for different crops which can be used as a basic tool for assessing the impact of climate variability on the risk for the potential yield or, furthermore for generating maps of uncertainty of yield for specific crops and specific agricultural areas. In addition, we applied a stack-ordering technique instead of the comprehensive Monte Carlo simulation for generating SCWPFs, which are based on a statistically appropriate sample size and a reliable optimal management. In comparison to an always exhaustive evaluation of the realizations in the case of the Monte Carlo set the stack-ordering procedure yields considerable computational savings by identifying critical solutions which define the user chosen reliability quantile in the course of the overlying optimization process.

  18. First clinical trial of tomographic neurofeedback in attention-deficit/hyperactivity disorder: evaluation of voluntary cortical control. (United States)

    Liechti, Martina D; Maurizio, Stefano; Heinrich, Hartmut; Jäncke, Lutz; Meier, Lea; Steinhausen, Hans-Christoph; Walitza, Susanne; Drechsler, Renate; Brandeis, Daniel


    Tomographic neurofeedback (tNF) training was evaluated as a treatment for attention-deficit/hyperactivity disorder (ADHD). To investigate the specificity of the treatment, outcomes were related to learning during tNF. Thirteen children with ADHD trained over 36 lessons to regulate their brain activity in the anterior cingulate cortex (ACC) using both theta-beta frequency and slow cortical potential (SCP) protocols. Thirty-channel electroencephalogram (EEG) was used to calculate low-resolution electromagnetic tNF and to assess the course of the training. Pre- and post-assessments included questionnaires, tests of attention, EEG recordings, and cognitive event-related potentials. Despite behavioural improvement and EEG artefact reduction, only partial learning was found for ACC parameters. Successful regulation was observed only for a simple feedback variant of SCP training, but with ACC-specific effects. Over training, resting EEG analysis indicated individual frequency normalisation rather than unidirectional changes across subjects. These results indicate that clinical improvement after ACC-tNF training can parallel artefact reduction without substantial learning of improved cortical control. However, individual normalisation of resting EEG activity and partial SCP control proved possible in this specific brain region affected in ADHD using tNF. Further studies are needed to clarify which critical aspects mediate region-specific learning in neurofeedback. This study is the first to systematically investigate tNF in children suffering from a psychiatric disorder. Copyright © 2012 International Federation of Clinical Neurophysiology.

  19. Multidisciplinary assessment of children with deficits relating to attention, motor activity and perception: evaluation of the ANSER model. (United States)

    Isberg, E; Kjellman, B


    This study describes a process for multidisciplinary assessment of children having deficits in attention, motor activity and perception (DAMP) with an evaluation of that process based on the opinions of parents, teachers and team members. The process named the 'ANSER model' consists of six steps (I to VI) conducted over a 2-month period and a follow-up 2 years later (step VII). Parents and teachers are fully involved early in the process and their participation is considered essential for a good result. Particular consideration is given to directly helping a child understand him/herself and become aware of his/her own difficulties. Strategies to overcome those difficulties are developed together with the child, the parents and the teacher. A specific aspect of the assessment is the aim to provide therapy through discussion of the questions, thoughts and feelings evoked during, and by the process. The expectations of parents and teachers regarding the assessment, and their completion of six steps of the process were ascertained from questionnaires. A large majority of both parents and teachers had high expectations of the assessment. Slightly more parents than teachers were convinced of its necessity. Their expectations were satisfied. Parents, teachers and team members emphasized the importance of the participation of parents and teachers in the process. The average time required for a complete assessment according to the process and including the work of all the specialists was 33 hours.

  20. Assessment of stigma associated with attention-deficit hyperactivity disorder: psychometric evaluation of the ADHD stigma questionnaire. (United States)

    Kellison, Ida; Bussing, Regina; Bell, Lindsay; Garvan, Cynthia


    This study evaluated the psychometric properties of the attention deficit hyperactivity disorder (ADHD) Stigma Questionnaire (ASQ) among a community sample of 301 adolescents ages 11-19 years at high (n=192) and low risks (n=109) for ADHD. Study subjects were drawn from a cohort study assessing ADHD detection and service use. The 26-item ASQ demonstrated good internal consistency. Confirmatory factor analysis using random parceling supported a three-factor structure with highly correlated subscales of disclosure concerns, negative self image, and concern with public attitudes, and a Schmid-Leiman analysis supported an overall stigma factor. Test-retest stability was assessed after two weeks (n=45) and found to be adequate for all three subscales. Construct validity was supported by relationships with related constructs, including clinical maladjustment, depression, self-esteem, and emotional symptoms, and the absence of a relationship with school maladjustment. Findings indicate that the ASQ has acceptable psychometric properties in a large community sample of adolescents, some of whom met Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV) criteria for ADHD.

  1. Evaluating the content of Individualized Education Programs and 504 Plans of young adolescents with attention deficit/hyperactivity disorder. (United States)

    Spiel, Craig F; Evans, Steven W; Langberg, Joshua M


    The purpose of this study was to evaluate the degree with which Individualized Education Programs (IEPs) and 504 Plans prepared for middle school students with attention deficit/hyperactivity disorder (ADHD) conformed to best practices and included evidence-based services. Specifically, we examined the problem areas identified in the statement of students' present level of academic achievement and functional performance (PLAAFP) and targeted in the students' measurable annual goals and objectives (MAGOs). In addition, we compared services with lists of recommended services provided by the U.S. Department of Education (ED) and reviews of evidence-based practices. Participants were 97 middle school students with ADHD, 61.9% with an IEP, and 38.1% with a 504 Plan. Most (85%) IEP PLAAFP statements described nonacademic/behavior problems, but fewer than half had MAGOs targeting these areas of need. Services listed on IEPs and Section 504 Plans were frequently consistent with ED recommendations, but had little to no research supporting their effectiveness. In addition, services with evidence supporting benefit to students with ADHD were rarely included on IEPs or 504 Plans. Implications for special education policy and future directions are discussed.

  2. Relationship between neuropsychological impairment and grey and white matter changes in adult-onset myotonic dystrophy type 1

    Directory of Open Access Journals (Sweden)

    Sigrid Baldanzi


    TBSS results indicate that the involvement of normal appearance WM, beyond the signal changes detected with conventional MR imaging (Fazekas scale and LL%, was associated with neuropsychological deficit. These data suggest that disrupted complex neuronal networks can underlie cognitive-behavioural dysfunctions in DM1.

  3. Neuropsychological functioning in youth with obsessive compulsive disorder: an examination of executive function and memory impairment. (United States)

    Lewin, Adam B; Larson, Michael J; Park, Jennifer M; McGuire, Joseph F; Murphy, Tanya K; Storch, Eric A


    Preliminary research suggests neuropsychological deficits in youth with obsessive-compulsive disorder (OCD) similar to those in adults; however, small samples and methodological confounds limit interpretation. We aimed to examine the rates and clinical correlates of cognitive sequelae in youth with OCD, focusing on executive functioning and memory abilities. Youth ages 7-17 years with OCD (N=96) completed a hypothesis-driven neuropsychological battery (including the Rey-Osterreith Complex Figure, California Verbal Learning Test, and subtests of the Delis-Kaplan Executive Function System and Wide Range Assessment of Memory and Learning) that primarily assessed executive functioning, memory and processing speed. Cognitive sequelae were identified in 65% of youth (37% using a more stringent definition of impairment). Magnitude of cognitive sequelae was not associated with OCD severity or age; however, greater neuropsychological impairments were found amongst youth prescribed atypical neuroleptics and those diagnosed with comorbid tic disorders. Comorbidity burden was associated with presence of neuropsychological impairment, but was not specific to any single test. Findings suggest that the presence of cognitive sequelae is prevalent amongst treatment-seeking youth with OCD. Deficits were found in executive functioning and non-verbal memory performance but these impairments were not associated with OCD severity. Copyright © 2014 Elsevier Ireland Ltd.

  4. Drug-related decrease in neuropsychological functions of abstinent drug users. (United States)

    van Holst, Ruth Janke; Schilt, Thelma


    This article reviews neuropsychological performance in frequent users of cocaine, (meth)amphetamines, ecstasy, opiates, alcohol, and cannabis. We searched the scientific literature published in the last five years, focusing on studies that required at least 2 weeks of abstinence from drug use, and included a control group. All substances of abuse, except cannabis, were associated with sustained deficits in executive functioning, especially inhibition. In addition, verbal memory decrements were consistently found in cocaine, (meth)amphetamines and ecstasy users, but not in heroin or cannabis users. More specific executive functioning deficits were reported depending on the substance of abuse. Cocaine was associated with diminished cognitive flexibility, whereas (meth)amphetamines were associated with worse cognitive planning functions compared to controls. Opiate studies showed lower scores on verbal fluency in opiate dependent subjects compared to controls. Working memory and visuospatial abilities were compromised in alcohol abusers. In ecstasy users, inconsistent findings have been reported across neuropsychological domains, with the exception of inhibition and verbal memory. There was little evidence for sustained cognitive impairments in adult abstinent cannabis users. Recognition of neuropsychological problems related to different substances can help to select subjects that will benefit most from treatment. Furthermore, a better understanding of the neuropsychological impairments in drug abusing individuals could help to explain the remitting course of substance abuse disorders and to improve psychological interventions.

  5. Neuropsychological performance, impulsivity, ADHD symptoms, and novelty seeking in compulsive buying disorder. (United States)

    Black, Donald Wayne; Shaw, Martha; McCormick, Brett; Bayless, John David; Allen, Jeff


    We examined the neuropsychological performance of people with compulsive buying disorder (CBD) and control subjects, along with trait impulsivity, symptoms of attention deficit hyperactivity disorder (ADHD), and selected personality characteristics. Subjects received a comprehensive neuropsychological test battery, depression and ADHD symptom assessment, the Barratt Impulsiveness Scale, and a version of the Temperament and Character Inventory. Persons with CBD (n=26) and controls (n=32) were comparable in terms of age, sex, and years of education. Subjects with CBD had a mean age of 36.3 years (S.D.=15.7) and an age at onset of 19.7 years (S.D.=7.0). Compulsive buyers had more lifetime mood, anxiety, and impulse control disorders. People with Compulsive buying performed significantly better on the Wechsler Abbreviated Scale of Intelligence Picture Completion task, a test of visual perception; otherwise, there were no consistent differences in neuropsychological measures. They also had elevated levels of self-reported depression, ADHD symptoms, trait impulsivity, and novelty seeking. In conclusion, compulsive buyers have greater lifetime psychiatric comorbidity than controls, and higher levels of self-rated depression, ADHD symptoms, trait impulsivity, and novelty seeking. The present study does not support the notion that there is a pattern of neuropsychological deficits associated with CBD. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

  6. The evaluation of a question prompt list for attention-deficit/hyperactivity disorder in pediatric care: A pilot study. (United States)

    Ahmed, Rana; McCaffery, Kirsten J; Silove, Natalie; Butow, Phyllis; Clarke, Simon; Kohn, Michael; Aslani, Parisa

    Of the available treatment options for attention-deficit/hyperactivity disorder (ADHD), the use of medications remains the most controversial and it is often difficult for parents to make decisions about treatment. Provision of relevant, reliable information about treatment during consultations may help address parents' concerns about treatment options. Question prompt lists are structured lists of disease and treatment-specific questions intended for use by patients during consultations to encourage communication with clinicians. They may prove useful in empowering parents to ask questions during consultations and to make informed decisions about treatments for ADHD. To evaluate the acceptability and usefulness of a question prompt list (QPL) for attention-deficit/hyperactivity disorder (ADHD) during consultations between parents of diagnosed children and their pediatricians. Parents of children recently diagnosed with ADHD (n = 17) received a copy of the QPL 7 days before their child's appointment and completed questionnaires before and after their consultations to elicit: satisfaction with the consultation and QPL; situational anxiety levels; achievement of decision-making and information preferences. Pediatricians (n = 3) completed questionnaires after each consultation to determine the impact of the QPL on consultation flow and to ascertain their willingness to incorporate the QPL into their practice. All parents reported that the QPL helped them to ask more questions, was easy to understand and would be useful to them in future. After receiving the QPL and seeing the pediatrician, parents' anxiety decreased significantly. All described their decision-making roles as 'just right' and were satisfied with the information obtained during their consultations. All pediatricians agreed that the QPL was helpful for parents, made communication easier, and helped parents to initiate discussion about difficult topics. The QPL was not found to impede flow of the

  7. Impulsivity and verbal deficits associated with domestic violence. (United States)

    Cohen, Ronald A; Brumm, Virdette; Zawacki, Tricia M; Paul, Robert; Sweet, Lawrence; Rosenbaum, Alan


    While neurobiological factors are known to play a role in human aggression, relatively few studies have examined neuropsychological contributions to propensity for violence. We previously demonstrated cognitive deficits among men who committed domestic violence (batterers) compared to non-violent controls. Batterers had deficits in verbal ability, learning and executive problem-solving ability. These findings led us to examine whether executive control problems involving impulsivity contribute to problems with behavioral control among batterers, and to further examine their deficits in verbal functioning. Batterers (n = 41) enrolled in a domestic violence program were compared to 20 non-violent men of similar age, education, and socioeconomic background on neuropsychological tests of executive functioning, including impulsivity. Questionnaires and structured clinical interviews were used to assess emotional distress, aggression and self-reported impulsivity. Batterers showed greater impulsivity compared to non-batterers on several neuropsychological measures. Yet, the severity of these deficits was relatively mild and not evident in all batterers. Consistent with our previous findings, significant verbal deficits were again observed among the batterers. These findings suggest that while impulsivity may be a factor associated with domestic violence, it probably is not the sole determinant of the strong relationship between cognitive functioning and batterer status that we previously observed. Both verbal expressive deficits and behavioral impulsivity appear to be relevant variables in predisposing men to domestic violence.

  8. Neuropsychological and psychological interventions for people with newly diagnosed epilepsy. (United States)

    Jackson, Cerian F; Makin, Selina M; Baker, Gus A


    Many people with epilepsy report experiencing psychological difficulties such as anxiety, depression and neuropsychological deficits including memory problems. Research has shown that these difficulties are often present not only for people with chronic epilepsy but also for people with newly diagnosed epilepsy. Despite this, there are very few published interventions that detail means to help people with newly diagnosed epilepsy manage these problems. To identify and assess possible psychological and neuropsychological interventions for adults with newly diagnosed epilepsy. We searched the following databases on 30 June 2015: the Cochrane Epilepsy Group Specialized Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (Ovid), SCOPUS, PsycINFO, CINAHL, and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP). This review includes all randomised controlled trials, quasi-randomised controlled trials, prospective cohort controlled studies, and prospective before and after studies which include psychological or neuropsychological interventions for people with newly diagnosed epilepsy. We excluded studies that included people with epilepsy and any other psychological disorder or neurological condition. We excluded studies carried out which recruited only children. We used the standard methodological procedure expected by The Cochrane Collaboration. Two authors independently completed data extraction and risk of bias analysis. The results of this were cross-checked and third author resolved any discrepancies. In the event of missing data, we contacted the study authors. Meta-analysis was not completed due to differences in the intervention and outcomes reported in the two studies. We included two randomised controlled trials assessing psychological interventions for people with newly diagnosed epilepsy. One study assessed a cognitive behavioural intervention (CBI) in an adolescent

    Kerns, Kimberley A.; Don, Audrey; Mateer, Catherine A.; Streissguth, Ann P.


    Sixteen nonretarded young adults with fetal alcohol syndrome were divided into two groups, one with average to above average IQ and one with borderline to low average IQ. Subjects in both groups manifested clear deficits on neuropsychological measures sensitive to complex attention, verbal learning, and executive function at a frequency and…

  11. Long-term neuropsychological outcomes in children and adolescents after cardiac arrest. (United States)

    van Zellem, Lennart; Buysse, Corinne; Madderom, Marlous; Legerstee, Jeroen S; Aarsen, Femke; Tibboel, Dick; Utens, Elisabeth M


    Research into neuropsychological functioning of survivors of cardiac arrest (CA) in childhood is scarce. We sought to assess long-term neuropsychological functioning in children and adolescents surviving CA. Neuropsychological follow-up study involving all consecutive children surviving CA between January 2002 and December 2011. Intelligence (IQ), language, attention, memory, visual-spatial, and executive functioning were assessed with internationally validated, neuropsychological tests and questionnaires. Scores were compared with Dutch normative data. Of 107 eligible children, 47 who visited the outpatient clinic (median follow-up interval: 5.6 years) were analyzed. Fifty-five percent had an in-hospital CA, 86% a non-shockable rhythm, and 49% a respiratory-related etiology. CA survivors scored significantly worse on full-scale IQ (mean = 87.3), verbal IQ (mean = 92.7), performance IQ (mean = 85.6), verbal comprehension index (mean = 93.4), perceptual organization index (mean = 83.8), and processing speed index (mean = 91.1), than the norm population (mean IQ = 100). On neuropsychological tests, compared with norms, respectively adjusted for IQ, significantly worse scores were found on visual memory, significantly better on verbal memory (recognition), and comparable outcomes on visual-motor integration, attention, other measures of verbal memory, and executive functioning. On questionnaires, parents reported better executive functioning than the norm, but teachers reported more problems in planning/organizing skills. Long-term neuropsychological assessment of CA survivors showed significant weaknesses, but also relatively intact functioning. As deficits in IQ, memory and executive functioning have significant impact on the child, long-term follow-up and neuropsychological support of CA survivors is warranted.

  12. Ecological validity of pediatric neuropsychological measures: current state and future directions. (United States)

    Olson, Katie; Jacobson, Kristin K; Van Oot, Peter


    Neuropsychologists are increasingly requested to identify specific deficits in cognitive abilities and determine the ways in which these deficits will affect a client's everyday functioning. The demand for prescriptive diagnostic endeavors that provide recommendations for rehabilitation has drawn attention to the necessity of considering the ecological validity of instruments. Most of the current knowledge regarding the ecological validity of neuropsychological measures is the result of studies examining adult and older adult populations. The relationship of test performance and everyday functioning in children has been less examined and is, therefore, less understood. The purpose of this article is to provide a brief history of ecological validity in neuropsychology, discuss why this is an important consideration when working with child populations, and provide suggestions for continued research in this field.

  13. Nonsignificance of sleep relative to IQ and neuropsychological scores in predicting academic achievement. (United States)

    Mayes, Susan Dickerson; Calhoun, Susan L; Bixler, Edward O; Vgontzas, Alexandros N


    The goal of the study was to determine the relative importance of sleep, IQ, neuropsychological, and attention-deficit/hyperactivity disorder (ADHD) scores in predicting academic achievement. Objective overnight polysomnograph sleep scores, parent ratings of sleep problems, IQ, neuropsychological test scores, and parent ratings of ADHD were used to predict academic achievement in a general population sample of 412 elementary schoolchildren, 6 to 12 years of age with IQs of 71 to 147. Using stepwise linear regression analysis, IQ was the best single predictor of reading and math achievement test scores. The most powerful combined predictors of achievement were IQ and some of the neuropsychological test scores. Subjective parent-reported sleep problems and objective polysomnograph scores (apnea-hypopnea index, mean oxygen saturation and lowest saturation percentage during sleep, snoring frequency and severity, sleep latency, minutes to rapid eye movement (REM) sleep, arousal index, number of awakenings, sleep efficiency, and percentage of stage 1, 2, 3, 4, and REM sleep) did not contribute significantly more to the prediction of achievement. Children with and without sleep problems did not differ from each other in achievement. IQ, neuropsychological test scores, and ADHD ratings were all significantly related to achievement, but correlations between achievement and objective and subjective sleep scores were all nonsignificant. There may be individual children for whom sleep problems affect achievement, but for a large group of community children, sleep was not significantly related to academic functioning. In contrast, IQ and neuropsychological test scores were powerful predictors of achievement.

  14. Neuropsychological comparisons of cocaine versus methamphetamine users: a research synthesis and meta-analysis. (United States)

    Hall, Matthew G; Hauson, Alexander O; Wollman, Scott C; Allen, Kenneth E; Connors, Eric J; Stern, Mark J; Kimmel, Christine L; Stephan, Rick A; Sarkissians, Sharis; Barlet, Brianna D; Grant, Igor


    Previous meta-analytical research examining cocaine and methamphetamine separately suggests potentially different neuropsychological profiles associated with each drug. In addition, neuroimaging studies point to distinct structural changes that might underlie differences in neuropsychological functioning. This meta-analysis compared the effect sizes identified in cocaine versus methamphetamine studies across 15 neuropsychological domains. Investigators searched and coded the literature examining the neuropsychological deficits associated with a history of either cocaine or methamphetamine use. A total of 54 cocaine and 41 methamphetamine studies were selected, yielding sample sizes of 1,718 and 1,297, respectively. Moderator analyses were conducted to compare the two drugs across each cognitive domain. Data revealed significant differences between the two drugs. Specifically, studies of cocaine showed significantly larger effect-size estimates (i.e., poorer performance) in verbal working memory when compared to methamphetamine. Further, when compared to cocaine, methamphetamine studies demonstrated significantly larger effect sizes in delayed contextual verbal memory and delayed visual memory. Overall, cocaine and methamphetamine users share similar neuropsychological profiles. However, cocaine appears to be more associated with working memory impairments, which are typically frontally mediated, while methamphetamine appears to be more associated with memory impairments that are linked with temporal and parietal lobe dysfunction.

  15. MENTAL AND PSYCHOMOTOR RETARDATION IN EARLY CHILDHOOD: Overview and development of a protocol for neuropsychological assessment.

    Directory of Open Access Journals (Sweden)

    María del Mar Sánchez-Joya


    Full Text Available Introduction: The last decades have brought great advances in the understanding of child neurodevelopment and knowledge of cognitive processes that occur in the brain from an early age. As a result and thanks to the large number of standardized and scientifically guaranteed neuropsychological tests that are available today, we can assess and diagnose with high specificity, deficits or delays in the acquisition of cognitive functions. Besides, it allows knowing the strengths or normality points of children with various pathologies. Objective: To present the concepts and a neuropsychological assessment protocol for mental retardation, pervasive developmental disorder and psychomotor retardation. Development: First, the authors present a general model of neuropsychological assessment in childhood. Second, he concept, classification and aetiology of mental retardation is revised and it is proposed a neuropsychological profile. Finally, the paradigms of pervasive developmental disorder and psychomotor retardation are shown. Conclusion: Based on standardized and validated test for child neuropsychological assessment, children cognitive disorders can be accurately identified to plan each child's cognitive stimulation, and thus optimize the results of the therapy.

  16. [Idiopathic generalized epilepsies with absence seizures with valproic acid treatment: neuropsychological disorders]. (United States)

    Conde-Guzon, P A; Cancho-Candela, R


    To analyze the neuropsychological profile of children with absence seizures treated with valproate. Sample of 34 children from 7 to 12 years with absence seizures treated with valproate (median dose: 30 mg/kg/day) and 28 controls. We get the neuropsychological profile by applying the Wechsler Intelligence Scale for Children-Revised (WISC-R) and Luria-DNI Battery. Children with absence seizures manifest verbal IQ significantly lower (p grammar. This is a serious deterioration profile in the areas of logical memory, short-term memory, arithmetic, numerical structure, reading, writing, naming, and articulation. Children with absence seizures have a significant memory deficit. Memory profile measured with the Luria-DNI Battery and the WISC-R appears generally deteriorated when compared with the control group (p < 0.001) although there is a paradoxical preservation of shape memory. The short-term auditory and visual memory and logical memory are particularly affected. In the epileptic group, the attentional profile (estimated by the 'third factor of the WISC-R') is generally deteriorated when compared with the control group. We consider in children with this diagnosis and treatment, the neuropsychological profile described to strengthen deficient neuropsychological and psychoeducational areas. Above, we claim the need, in the consultations of neuropediatrics, the neuropsychlogists to ensure the systematic analysis of neuropsychological and cognitive difficulties both at the time of the diagnosis and follow-up of epilepsy.

  17. Evaluation of sleep organization in patients with attention deficit hyperactivity disorder (ADHD) and ADHD as a comorbidity of epilepsy. (United States)

    Kalil Neto, Felipe; Nunes, Magda L


    Epilepsy or attention deficit hyperactivity disorder (ADHD) can influence sleep organization in different ways. The aim of this study was to evaluate sleep organization in children and adolescents with ADHD and epilepsy, and to analyze the influence of methylphenidate. This was an observational, cross-sectional study of children and adolescents with epilepsy, who were seizure free for at least three months, and were also diagnosed with ADHD. They were selected from the epilepsy and child neurology outpatient clinic of a university hospital in Brazil. After sample size calculation, patients were consecutively included into four different groups, with 21 patients each: epilepsy + ADHD using methylphenidate, epilepsy + ADHD not using methylphenidate, only ADHD, and a healthy control group. All participants were evaluated with the Sleep Disturbance Scale for Children (SDSC) and monitored with actigraphy for five nights/days. Actigraphic analysis showed a higher number of night awakenings in the epilepsy + ADHD groups; they were most prominent in the group without methylphenidate (p = 0.001). Parental reports demonstrated a higher risk for sleep disturbances in the epilepsy + ADHD without methylphenidate and the ADHD groups (p ADHD as a comorbidity of epilepsy impairs sleep organization in children, and the use of short-acting methylphenidate seems to improve it. Both objective (actigraphic) and subjective (SDSC) measures showed significant sleep alterations between primary ADHD and ADHD as a comorbidity of epilepsy; this was most prominent in the group without methylphenidate.

  18. Markov model for characterizing neuropsychologic impairment and Monte Carlo simulation for optimizing efavirenz therapy. (United States)

    Bisaso, Kuteesa R; Mukonzo, Jackson K; Ette, Ene I


    The study was undertaken to develop a pharmacokinetic-pharmacodynamic model to characterize efavirenz-induced neuropsychologic impairment, given preexistent impairment, which can be used for the optimization of efavirenz therapy via Monte Carlo simulations. The modeling was performed with NONMEM 7.2. A 1-compartment pharmacokinetic model was fitted to efavirenz concentration data from 196 Ugandan patients treated with a 600-mg daily efavirenz dose. Pharmacokinetic parameters and area under the curve (AUC) were derived. Neuropsychologic evaluation of the patients was done at baseline and in week 2 of antiretroviral therapy. A discrete-time 2-state first-order Markov model was developed to describe neuropsychologic impairment. Efavirenz AUC, day 3 efavirenz trough concentration, and female sex increased the probability (P01) of neuropsychologic impairment. Efavirenz oral clearance (CL/F) increased the probability (P10) of resolution of preexistent neuropsychologic impairment. The predictive performance of the reduced (final) model, given the data, incorporating AUC on P01and CL /F on P10, showed that the model adequately characterized the neuropsychologic impairment observed with efavirenz therapy. Simulations with the developed model predicted a 7% overall reduction in neuropsychologic impairment probability at 450 mg of efavirenz. We recommend a reduction in efavirenz dose from 600 to 450 mg, because the 450-mg dose has been shown to produce sustained antiretroviral efficacy. © 2015, The American College of Clinical Pharmacology.

  19. Motor assessment in pediatric neuropsychology: relationships to executive function. (United States)

    Shaheen, Sandra


    Executive function often refers to control behaviors such as "initiating," "sustaining," "inhibiting," and "switching." These mechanisms contribute to regulation of thinking and emotion but can be observed most clearly in the motor system. Neuropsychology has been influenced by "top-down" models of cognitive control that emerged from information-processing theories of cognition. In fact, neural models provide evidence that control processes are highly interactive within the cortico-striatal-cerebellar circuits. Cognition unfolds in response to motor-driven adaptation, and evidence exists for similar firing of brain cells and circuits during "imagined action" as in actual motor behavior. The motor system develops early and yet is not routinely assessed in neuropsychological evaluation of children with neurodevelopmental disorders. This article reviews some of the approaches to motor assessment that have sensitivity to neurodevelopmental disorders, and advocates for inclusion of motor assessment, particularly in evaluating control processes independent of culture, language, and other confounders.

  20. Deficits in Social Cognition: An Unveiled Signature of Multiple Sclerosis. (United States)

    Chalah, Moussa A; Ayache, Samar S


    Multiple sclerosis (MS) is a chronic progressive inflammatory disease of the central nervous system, representing the primary cause of non-traumatic disability in young adults. Cognitive dysfunction can affect patients at any time during the disease process and might alter the six core functional domains. Social cognition is a multi-component construct that includes the theory of mind, empathy and social perception of emotions from facial, bodily and vocal cues. Deficits in this cognitive faculty might have a drastic impact on interpersonal relationships and quality of life (QoL). Although exhaustive data exist for non-social cognitive functions in MS, only a little attention has been paid for social cognition. The objectives of the present work are to reappraise the definition and anatomy of social cognition and evaluate the integrity of this domain across MS studies. We will put special emphasis on neuropsychological and neuroimaging studies concerning social cognitive performance in MS. Studies were selected in conformity with PRISMA guidelines. We looked for computerized databases (PubMed, Medline, and Scopus) that index peer-reviewed journals to identify published reports in English and French languages that mention social cognition and multiple sclerosis, regardless of publication year. We combined keywords as follows: (facial emotion or facial expression or emotional facial expressions or theory of mind or social cognition or empathy or affective prosody) AND multiple sclerosis AND (MRI or functional MRI or positron emission tomography or functional imaging or structural imaging). We also scanned references from articles aiming to get additional relevant studies. In total, 26 studies matched the abovementioned criteria (26 neuropsychological studies including five neuroimaging studies). Available data support the presence of social cognitive deficits even at early stages of MS. The increase in disease burden along with the "multiple disconnection syndrome

  1. Correlation between neuropsychological and social cognition measures and symptom dimensions in schizophrenic patients. (United States)

    Altamura, A Carlo; Caletti, Elisabetta; Paoli, Riccardo Augusto; Cigliobianco, Michela; Zugno, Elisa; Grillo, Paolo; Prunas, Cecilia; Caldiroli, Alice; Zago, Stefano


    Neurocognitive and social cognition deficits have been largely reported in Schizophrenia (SKZ) but their association with psychopathology remains uncertain. Our purpose was to explore the relationship between symptom dimensions and neuropsychological performances. We enrolled 35 stabilized schizophrenic outpatients of the Department of Psychiatry of Policlinico Hospital, University of Milan, who completed psychiatric Rating Scales, the Brief Assessment of Cognition in Schizophrenia (BACS) and the Executive and Social Cognition Battery (ESCB). Disorganized dimension seems to have the most significant impact on cognition, being associated with performance in several BACS subtests (verbal memory, working memory, motor speed, symbol coding, Tower of London) and ESCB tasks (MET and Hotel task number of tasks attempted, number of broken MET rules, sum of deviations in Hotel Task). Positive dimension correlated with performance in verbal fluency, negative dimension with IOWA Test results, cognitive dimension with MET number of inefficiencies and Eyes test score. Impulsive-aggressive and depressive dimensions weakly correlated only with Faux Pas test. Our study supports the existence of a specific disorganized dimension in SKZ, separated from cognitive dimension evaluated through clinical instruments (e.g. PANSS), but capable of influencing cognitive abilities. Furthermore, it strengthens the validity of ecological tasks in evaluating cognition in SKZ. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

  4. Neuropsychological testing of patients with borderline personality disorder. (United States)

    O'Leary, K M; Brouwers, P; Gardner, D L; Cowdry, R W


    This study examined whether a battery of neuropsychological tests could detect cognitive deficits--particularly in the areas of perception, learning, and memory--in patients with borderline personality disorder. The test battery was completed by 16 research outpatients with borderline personality disorder, typified by behavioral dyscontrol and diagnosed according to DSM-III-R criteria and the Diagnostic Interview for Borderline Patients. A comparison group of 16 normal volunteers also completed the test battery. The performance of the borderline patients was significantly impaired in comparison with that of the normal group on memory tests requiring uncued recall of complex, recently learned material. Cues given on an auditory memory task partially corrected that deficit. The patients' performance was also significantly impaired on several visual perceptual tests. These deficits do not appear to have been attributable to attentional problems, psychomotor impairment, current major depression, or history of alcohol abuse. The observed difficulties in separating essential from extraneous visual information and in recalling complex material may be relevant in understanding some of the clinical features of borderline personality disorder. The observed memory improvement resulting from cueing suggests specific strategies that may be used to aid patients' recall of complex material.

  5. Neuropsychological Basis of Self Development

    Directory of Open Access Journals (Sweden)

    Mehmet Emin Ceylan


    Full Text Available There are a connection between the face recognition, the social relationship and the development of self. There must be a reason that people recognize faces through an important and complex module like the language functions. People know each other, recognize their friends and enemies and make friends through their faces. These show its fundamental role in the world. Like the integrity builds by collective self in inner world, integrity is established through face outside worlds. Researches and comments about the center of self in the brain are made based on neurological disorders like prosopagnosia. Especially some investigations about the evoked potentials will provide us a scientific basic for this subject. This paper addresses the relationship between facial recognition and self-development in terms of neuropsychological aspects.

  6. Evaluation of Brāhmī ghṛtam in children suffering from Attention Deficit Hyperactivity Disorder

    Directory of Open Access Journals (Sweden)

    Supriya Bhalerao


    Full Text Available Introduction: Attention Deficit Hyperactivity Disorder (ADHD is characterized by a persistent pattern of inattention and/or hyperactivity-impulsivity. In view of the adverse effects associated with psycho-stimulants used for the treatment of this disorder, efficacy of Brāhmīghṛtam was evaluated in this condition. Materials and Methods: After following due ethical considerations, children of either sex between the age group of 6 and 12 years diagnosed to be suffering from mixed variety of ADHD as per The Diagnostic and Statistical Manual of Mental Disorders (DSM IV criteria irrespective of other co-morbid psychiatric illnesses were recruited in the study. Initially a pilot study (n = 10 was carried out to confirm the efficacy of the identified dose of Brāhmīghṛtam. Using this dose, further therapeutic confirmatory study (n = 27 was carried out, wherein Brāhmīghṛtam was compared with methylphenidate. Effect on ADHD symptoms was assessed using the Dupaul ADHD rating scale and this was the main efficacy parameter. Results: In the pilot exploratory study, Brāhmīghṛtam showed 66% decrease in total ADHD score. In the therapeutic confirmatory study, only 16% improvement was seen with Brāhmīghṛtam, which was similar to methylphenidate, standard treatment for ADHD that was used as a comparator in the present study. No side-effects were reported in both studies. Conclusion: Our study thus has adequately demonstrated efficacy and safety of Brāhmīghṛtam in ADHD.

  7. Examining health-related quality of life, adaptive skills, and psychological functioning in children and adolescents with epilepsy presenting for a neuropsychological evaluation. (United States)

    Clary, Lauren E; Vander Wal, Jillon S; Titus, Jeffrey B


    The purpose of this study was to characterize 132 children and adolescents (mean age = 10 years, 11 months) with epilepsy in terms of psychosocial functioning and to determine the extent to which adaptive skills and psychological functioning predict health-related quality of life (HRQOL), above and beyond demographic and epilepsy-specific characteristics. A chart review was conducted to obtain demographic and epilepsy-specific information as well as caregiver responses on the Behavior Assessment System for Children, Second Edition (BASC-2) Parent Report and the Quality of Life in Childhood Epilepsy Questionnaire (QOLCE). In addition to Full Scale IQ and age at seizure onset, the BASC-2 Clinical and Adaptive Skills subscales also predicted HRQOL, indicating that this measure may be particularly helpful in predicting HRQOL above and beyond information routinely collected in a medical setting. It is imperative to evaluate children with epilepsy for psychosocial difficulties and diminished HRQOL to ensure the provision of comprehensive quality care and intervention services.

  8. The Technology Crisis in Neuropsychology. (United States)

    Miller, Justin B; Barr, William B


    Neuropsychology has fallen reliant on outdated and labor intensive methods of data collection that are slow, highly inefficient, and expensive, and provide relatively data-poor estimates of human behavior despite rapid technological advance in most other fields of medicine. Here we present a brief historical overview of current testing practices in an effort to frame the current crisis, followed by an overview of different settings in which technology can and should be integrated. Potential benefits of laboratory based assessments, remote assessments, as well as passive and high-frequency data collection tools rooted in technology are discussed, along with several relevant examples and how these technologies might be deployed. Broader issues of data security and privacy are discussed, as well as additional considerations to be addressed within each setting. Some of the historical barriers to adoption of technology are also presented, along with a brief discussion of the remaining uncertainties. While by no means intended as a comprehensive review or prescriptive roadmap, our goal is to show that there are a tremendous number of advantages to technologically driven data collection methods, and that technology should be embraced by the field. Our predictions are that the comprehensive assessments of the future will likely entail a combination of lab-based assessments, remote assessments, and passive data capture, and leading the development of these efforts will cement the role of neuropsychology at the forefront of cognitive and behavioral science. © The Author 2017.

  9. Motivational deficits and cognitive test performance in schizophrenia. (United States)

    Fervaha, Gagan; Zakzanis, Konstantine K; Foussias, George; Graff-Guerrero, Ariel; Agid, Ofer; Remington, Gary


    Motivational and cognitive deficits are core features of schizophrenia, both closely linked with functional outcomes. Although poor effort and decreased motivation are known to affect performance on cognitive tests, the extent of this relationship is unclear in patients with schizophrenia. To evaluate the association between intrinsic motivation and cognitive test performance in patients with schizophrenia. Cross-sectional and 6-month prospective follow-up study performed at 57 sites in the United States, including academic and community medical treatment centers, participating in the Clinical Antipsychotic Trials of Intervention Effectiveness study. The primary sample included 431 stable patients with a DSM-IV diagnosis of schizophrenia currently receiving a stable medication regimen. Cognitive performance and intrinsic motivation were evaluated using a comprehensive neuropsychological test battery and a derived measure from the Heinrichs-Carpenter Quality of Life Scale, respectively. Symptom severity and functional status were also assessed. The primary outcome variable was global neurocognition. Individual domains of cognition were also evaluated for their association with motivation. Level of intrinsic motivation was significantly and positively correlated with global cognitive test performance, a relationship that held for each domain of cognition evaluated (correlation range, 0.20-0.34; P motivation and cognitive performance also remained significant after controlling for antipsychotic dose (P motivation during the 6-month follow-up was also found to be significantly related to improvement in global cognitive performance (P motivation and cognitive performance and suggest that test performance is not purely a measure of ability. Future studies assessing cognition in patients with schizophrenia should consider potential moderating variables such as effort and motivation. Implications for the assessment and interpretation of cognitive impairment based on

  10. Applying Luria's diagnostic principles in the neuropsychological assessment of children. (United States)

    Korkman, M


    The first part of this article examines the theoretical justification for applying Luria's approach in the assessment of children. It is concluded that Luria's concepts of functional systems and the principle of specifying primary and secondary deficits may be applied to children. However, the selection of functional components to assess should be based on traditions of child neuropsychology rather than on Luria's assessment of adults. In addition, the tendency for comorbid disorders, mechanisms of neural adaptation to damage, and the prevalent types of brain abnormality in children render brain-behavior relationships more complex in children than in adults. The second part of the article describes how Luria's methods were adapted for use with children. An assessment, NEPSY, was developed by integrating Luria's views with contemporary child neuropsychological traditions. The NEPSY includes 27 homogeneous and psychometrically developed subtests, standardized in the United States and Finland for the age range of 3 to 12 years. The rationale of analyzing disorders of cognitive processes through a comprehensive and systematic assessment of their components, characteristic of Luria's approach, was preserved, but more specific principles of diagnosis were modified. Research findings obtained with a previously published, Finnish NEPSY version are presented.

  11. The ontogenesis of language impairment in autism: a neuropsychological perspective. (United States)

    Stefanatos, Gerry A; Baron, Ida Sue


    Autistic Disorder (AD) is a phenotypically heterogeneous condition characterized by impairments in social interaction, communication, and the presence of repetitive behavior and restricted interests. It is a model syndrome to investigate neural interaction and integration at the nexus of language and social cognition. This paper considers the problems of language acquisition in AD from an evolutionary and ontogenetic context. Following a review of normal language development during the formative years of brain development, we examine what is known about infant linguistic and nonlinguistic precursors of language acquisition in AD and examine how anomalies of several processes relate to language abnormalities manifest by the early elementary school years. Population heterogeneity and practical limitations inherent to the study of children currently limit a comprehensive understanding of the significance of specific neurological abnormalities in relation to observed deficits. However, convergent evidence implicates anomalies of a widely distributed neural network, involving superior temporal sulcus, superior temporal gyrus, supramarginal gyrus, insula, inferior frontal gyrus, hippocampus, amygdala and cerebellum. These anomalies reflect the cumulative effects of genetic, epigenetic and environmental influences. Neuropsychological studies of language in AD provide an important means to define the phenotypic variation resulting from alterations in neural architecture. By mapping broad relationships between key symptoms, neuropsychological impairment and neural substrate, information derived from these studies enable a level of analysis that bridges the gap between the genome and the syndrome. Further study of children during the critical first 2 years of life using behavioral, electrophysiological, and functional neuroimaging methods is essential.

  12. Neuropsychological analysis of an idiot savant: A case study. (United States)

    Puente, Antonio E; Heller, Stephanie; Sekely, Angela


    Although biological etiologies and diffuse anatomical changes have been provided as plausible explanations for the unusual behaviors observed in idiot savants, no neuropsychological case studies or explanations for these behaviors are found in the literature. We present a case in which the "diagnosis" of idiot savant was based on historical, clinical, and test data. To assess his calendar abilities, this individual was subsequently tested over a period of six months on his ability to determine the day of the week across approximately 1,000 years. For a period of approximately 100 years he was 100% accurate. The neuropsychological tests revealed marked deficits in all areas with performance generally in the lower 1-5th percentile of the population (e.g., Full Scale Intelligence Quotient [FSIQ] = 54). Tests of attention yielded the best scores although still deficient. General learning, coding, and executive function tests proved to be challenging. In contrast, tests of visuo-motor abilities were only of moderate difficulty for the individual. These findings are considered within the theoretical framework of Rimland (autism) and Squyres (memory).

  13. Comparative study of the neuropsychological and neuroimaging evaluations in children with dyslexia Estudo comparativo das avaliações neuropsicológicas e de neuroimagem em crianças com dislexia

    Directory of Open Access Journals (Sweden)

    Rodrigo Genaro Arduini


    Full Text Available We analyzed retrospectively the neuroimaging exams of children with a confirmed diagnosis of dyslexia and correlated our findings with the evaluation of higher cortical functions. We studied 34 medical files of patients of the Ambulatory of Neuro-difficulties in Learning, FCM/UNICAMP. All of them had been sent to the ambulatory with primary or secondary complaints of difficulties at school and were submitted to neuropsychological evaluation and imaging exam (SPECT. From the children evaluated 58.8% had exams presenting dysfunction with 47% presenting hypoperfusion in the temporal lobe. As for the higher cortical functions, the most affected abilities were reading, writing and memory. There was significance between the hypoperfused areas and the variables schooling, reading, writing, memory and mathematic reasoning. The SPECTs showed hypoperfusion in areas involved in the reading and writing processes. Both are equivalent in terms of involved functional areas and are similar in children with or without specific dysfunctions in neuroimaging.Analisamos retrospectivamente exames de neuroimagem de crianças com diagnóstico de dislexia e correlacionamos os achados com avaliação das funções corticais superiores. Estudamos 34 prontuários de pacientes atendidos no Ambulatório de Neuro-Dificuldades de Aprendizado, FCM/UNICAMP, no período de 1994 a 2002. Todas foram encaminhadas com queixa primária ou secundária de dificuldade escolar e submetidas à avaliação neuropsicológica e exame de imagem (SPECT. Das crianças avaliadas, 58,8% apresentaram exames alterados. Dentre as alterações, 16 possuíam hipoperfusão no lobo temporal. Nas funções corticais superiores, as habilidades mais prejudicadas foram leitura, escrita e memória. Houve significância entre as áreas hipoperfundidas com a variável escolaridade, leitura, escrita, memória e raciocínio matemático.

  14. Cognitive deficits in adults with obstructive sleep apnea compared to children and adolescents. (United States)

    Krysta, Krzysztof; Bratek, Agnieszka; Zawada, Karolina; Stepańczak, Radosław


    Obstructive sleep apnea (OSA) can negatively affect the patient's physical and psychological functioning, as well as their quality of life. A major consequence of OSA is impaired cognitive functioning. Indeed, several studies have shown that OSA mainly leads to deficits in executive functions, attention, and memory. As OSA can present in all age groups, these associated cognitive deficits have been observed in adults, as well as in children and adolescents. However, these cognitive deficits may have a different clinical picture in young patients compared to adults. In this review, we analyze the most affected cognitive domains in adults and children/adolescents with OSA, as evaluated by neuropsychological and neuroimaging studies. We found that deficits in working memory, attention, or executive functions cognitive domains are found in both adults and children with OSA. However, children with OSA also show changes in behavior and phonological processing necessary for proper development. Moreover, we examine the possible OSA treatments in children and adults that can have a positive influence on cognition, and therefore, improve patients' general functioning and quality of life.

    Godefroy, O; Leclercq, C; Bugnicourt, J-M; Roussel, M; Moroni, C; Quaglino, V; Beaunieux, H; Taillia, H; Nédélec-Ciceri, C; Bonnin, C; Thomas-Anterion, C; Varvat, J; Aboulafia-Brakha, T; Assal, F


    Vascular cognitive impairment (VCI) includes vascular dementia (VaD), vascular mild cognitive impairment (VaMCI) and mixed dementia. In clinical practice, VCI concerns patients referred for clinical stroke or cognitive complaint. To improve the characterization of VCI and to refine its diagnostic criteria, an international group has elaborated a new standardized evaluation battery of clinical, cognitive, behavioral and neuroradiological data which now constitutes the reference battery. The adaption of the battery for French-speaking subjects is reported as well as preliminary results of the on-going validation study of the GRECOG-VASC group [Clinical Trial NCT01339195]. The diagnostic accuracy of various screening tests is reviewed and showed an overall sub-optimal sensitivity (dementia. In addition to the well known NINDS-AIREN criteria of VaD, criteria of VCI have been recently proposed which are based on the demonstration of a cognitive disorder by neuropsychological testing and either history of clinical stroke or presence of vascular lesion by neuroimaging suggestive of a link between cognitive impairment and vascular disease. A memory deficit is no longer required for the diagnosis of VaD as it is based on the cognitive decline concerning two or more domains that affect activities of daily living. Both VaMCI and VaD are classified as probable or possible. These new criteria have yet to be validated. Considerable uncertainties remain regarding the determinant of VCI, and especially the lesion amount inducing VCI and VaD. The interaction between lesion amount and its location is currently re-examined using recent techniques for the analysis of MRI data. The high frequency of associated Alzheimer pathology is now assessable in vivo using amyloid imaging. The first studies showed that about a third of patients with VaD due to small vessel disease or with poststroke dementia have amyloid PET imaging suggestive of AD. These new techniques will examine the

    Age-related white matter changes have been associated with cognitive functioning, even though their role is not fully understood. This work aimed to test a 3-factor model of the neuropsychological assessment battery and evaluate how the model fit the data longitudinally. Confirmatory factor...... analysis (CFA) was used to investigate the dimensions of a structured set of neuropsychological tests administered to a multicenter, international sample of independent older adults (LADIS study). Six hundred and thirty-eight older adults completed baseline neuropsychological, clinical, functional...... and motor assessments, which were repeated each year for a 3-year follow-up. CFA provided support for a 3-factor model. These factors involve the dimensions of executive functions, memory functions, and speed and motor control abilities. Performance decreased in most neuropsychological measures. Results...

  17. Advanced Neuropsychological Diagnostics Infrastructure (ANDI: A Normative Database Created from Control Datasets.

    Directory of Open Access Journals (Sweden)

    Nathalie R. de Vent


    Full Text Available In the Advanced Neuropsychological Diagnostics Infrastructure (ANDI, datasets of several research groups are combined into a single database, containing scores on neuropsychological tests from healthy participants. For most popular neuropsychological tests the quantity and range of these data surpasses that of traditional normative data, thereby enabling more accurate neuropsychological assessment. Because of the unique structure of the database, it facilitates normative comparison methods that were not feasible before, in particular those in which entire profiles of scores are evaluated. In this article, we describe the steps that were necessary to combine the separate datasets into a single database. These steps involve matching variables from multiple datasets, removing outlying values, determining the influence of demographic variables, and finding appropriate transformations to normality. Also, a brief description of the current contents of the ANDI database is given.

  18. Neuropsychologic effects of cranial irradiation, intrathecal methotrexate, and systemic methotrexate in childhood cancer. (United States)

    Butler, R W; Hill, J M; Steinherz, P G; Meyers, P A; Finlay, J L


    To investigate the neuropsychologic effects of cranial irradiation (CRT), intrathecal methotrexate (IT-MTX), and systemic methotrexate (SYS-MTX) in a cohort of pediatric patients with cancer who had either received no, moderate, or high doses of these treatments alone or in various combinations. Data were collected on 120 pediatric cancer patients from a large variety of diagnostic groups. Patients completed a comprehensive neuropsychologic test battery designed to assess most areas of cognitive functioning. In analyzing cancer treatment effects, the following variables were statistically controlled: (1) age, (2) socioeconomic status (SES), (3) age at diagnosis, (4) months since both onset and cessation of CNS treatments, (5) time missed from schooling, and (6) presence/type of CNS cancer. CRT, largely in combination with IT-MTX, was significantly associated with deficits in several, primarily nondominant, hemispheric neuropsychologic functions, even after control and other treatment variables were addressed. This relationship was somewhat, but not highly, dose-dependent at CRT doses greater than approximately 18 Gy, at least over the first several years posttreatment. While there was statistically significant evidence for cognitive impairment, absence from school during treatment and age at diagnosis were more predictive of reading and spelling academic achievement than having received CRT. IT-MTX and SYS-MTX alone were not associated with significant degrees of neuropsychologic involvement. CRT, especially when administered with IT-MTX, at currently used dosages was associated with significant neuropsychologic impairment in children. These impairments are most likely to be reflected in nonverbal intelligence, perceptual abilities, and susceptibility to distraction. IT-MTX and SYS-MTX did not result in a consistent pattern of cognitive deficit.

  19. The neuropsychological and neuroradiological correlates of slowly progressive visual agnosia. (United States)

    Giovagnoli, Anna Rita; Aresi, Anna; Reati, Fabiola; Riva, Alice; Gobbo, Clara; Bizzi, Alberto


    The case of a 64-year-old woman affected by slowly progressive visual agnosia is reported aiming to describe specific cognitive-brain relationships. Longitudinal clinical and neuropsychological assessment, combined with magnetic resonance imaging (MRI), spectroscopy, and positron emission tomography (PET) were used. Sequential neuropsychological evaluations performed during a period of 9 years since disease onset showed the appearance of apperceptive and associative visual agnosia, alexia without agraphia, agraphia, finger agnosia, and prosopoagnosia, but excluded dementia. MRI showed moderate diffuse cortical atrophy, with predominant atrophy in the left posterior cortical areas (temporal, parietal, and lateral occipital cortical gyri). 18FDG-PET showed marked bilateral posterior cortical hypometabolism; proton magnetic resonance spectroscopic imaging disclosed severe focal N-acetyl-aspartate depletion in the left temporoparietal and lateral occipital cortical areas. In conclusion, selective metabolic alterations and neuronal loss in the left temporoparietooccipital cortex may determine progressive visual agnosia in the absence of dementia.

  20. Slowly progressive aphemia: a neuropsychological, conventional, and functional MRI study. (United States)

    Gallassi, R; Sambati, L; Poda, R; Oppi, F; Stanzani Maserati, M; Cevolani, D; Agati, R; Lodi, R


    Slowly progressive aphemia (SPA) is a rare focal degenerative disorder characterized by severe dysarthria, frequent orofacial apraxia, dysprosody, phonetic and phonemic errors without global cognitive deterioration for many years. This condition is caused by a degeneration of anterior frontal lobe regions, mainly of the left frontal operculum. We report a case of SPA with a course of 8 years, evaluated by repeated neuropsychological, conventional, and functional MRI examinations. In our case, neuropsychological examinations showed a progressive impairment of speech articulation including dysprosody, phonetic and phonemic errors, and slight writing errors. No global cognitive deterioration was detected and the patient is still completely autonomous. Morphological and functional investigations showed, respectively, a progressive atrophy and progressive impairment of the left frontal region, confirming the role of the opercular region in determining this rare syndrome. During verbal task generation as the cortical activation of this region gradually decreased, the language articulation worsened.

  1. The neuropsychology of attention: revisiting the "Mirsky model". (United States)

    Koziol, Leonard F; Joyce, Arthur W; Wurglitz, Glen


    Nearly 25 years ago, Mirsky and colleagues proposed a multiple-component model of attention. It was proposed that attention was characterized by several distinct elements that were organized into a system. A putative neuroanatomical substrate of this model of attention was proposed. This functional anatomy was primarily based upon inferences derived from brain lesion studies. Mirsky and colleagues developed a systematic clinical evaluation of this model by applying a group of neuropsychological tests. Since the introduction of what has been commonly referred to as the "Mirsky model," significant advances have been made in our understanding of brain-behavior relationships. This article applies current neuroscientific principles to "update" our understanding of attention and the "Mirsky model." We also demonstrate how the interpretation of neuropsychological tests can be modified according to principles of large-scale brain systems and patterns of brain network functional connectivity.

  2. From theory to PrACTice: a cognitive remediation program based on a neuropsychological model of schizophrenia

    Directory of Open Access Journals (Sweden)

    Delphine eFabre


    Full Text Available Cognitive dysfunction is one of the hallmark deficits of schizophrenia. A wide range of studies illustrate how it is strongly interconnected to clinical presentation and daily life functioning (see Green, 1996 and Green et al., 2000. Hence, cognition is an important treatment target in schizophrenia. To address the challenge of cognitive enhancement in schizophrenia, a large number of cognitive remediation programs have been developed and evaluated over the past several decades. First, an overview of these programs is presented highlighting their specificity to cognitive deficit in schizophrenia using an integrated method. In this case, cognitive training focuses on enhancing several elementary cognitive functions considered as a prerequisite to social skills or vocational training modules. These programs are based on the neurodevelopmental hypothesis of schizophrenia. However, moderate improvement for patients who benefit from these therapies has been observed as described in Wykes et al review (2011. Next, neuropsychological models of schizophrenia are then presented. They highlight the critical role of the internally generated intentions in appropriate willful actions. The cognitive control mechanism deals with this ability. Interestingly, available cognitive remediation programs have not been influenced by these models. Hence, we propose another alternative to set up a specific cognitive remediation program for schizophrenia patients by targeting the cognitive control mechanism. We describe the PrACTice program which is in the process of being validated.

  3. An Update of the Review of Neuropsychological Consequences of HIV and Substance Abuse: A Literature Review and Implications for Treatment and Future Research. (United States)

    Norman, Lisa R; Basso, Michael


    Neuropyschological dysfunction, ranging from mild cerebral indicators to dementia has been a consistent part of the medical picture of HIV/AIDS. However, advances in medical supervision, particularly as a result of antiretroviral (ARV) treatment, have resulted in some mitigation of the neuropsychological effects of HIV and necessitate re-evaluation of the pattern and nature of HIV-related cognitive or mental deficits. The associated enhancements in morbidity and mortality that have occurred as a result of ARV medication have led to a need for interventions and programs that maintain behaviors that are healthy and stop the resurgence of the risk of HIV transmission. Risk factors such as mental illness and substance use that may have contributed to the initial infection with HIV still need consideration. These risk factors may also increase neuropsychological dysfunction and impact observance of prevention for treatment and recommendations. Explicitly, a better comprehension of the role of substance use on the progression of HIV-related mental decline can enlighten management and evaluation of persons living with HIV with concurrent disorders of substance use. This review provides a summary of the neurophyschology of substance use and HIV and the existing research that has looked at the effects of both substance use and HIV disease on neurophyscological function and suggestions for future research and treatment.

  4. Auditory and Visual Working Memory Functioning in College Students with Attention-Deficit/Hyperactivity Disorder and/or Learning Disabilities. (United States)

    Liebel, Spencer W; Nelson, Jason M


    We investigated the auditory and visual working memory functioning in college students with attention-deficit/hyperactivity disorder, learning disabilities, and clinical controls. We examined the role attention-deficit/hyperactivity disorder subtype status played in working memory functioning. The unique influence that both domains of working memory have on reading and math abilities was investigated. A sample of 268 individuals seeking postsecondary education comprise four groups of the present study: 110 had an attention-deficit/hyperactivity disorder diagnosis only, 72 had a learning disability diagnosis only, 35 had comorbid attention-deficit/hyperactivity disorder and learning disability diagnoses, and 60 individuals without either of these disorders comprise a clinical control group. Participants underwent a comprehensive neuropsychological evaluation, and licensed psychologists employed a multi-informant, multi-method approach in obtaining diagnoses. In the attention-deficit/hyperactivity disorder only group, there was no difference between auditory and visual working memory functioning, t(100) = -1.57, p = .12. In the learning disability group, however, auditory working memory functioning was significantly weaker compared with visual working memory, t(71) = -6.19, p attention-deficit/hyperactivity disorder only group, there were no auditory or visual working memory functioning differences between participants with either a predominantly inattentive type or a combined type diagnosis. Visual working memory did not incrementally contribute to the prediction of academic achievement skills. Individuals with attention-deficit/hyperactivity disorder did not demonstrate significant working memory differences compared with clinical controls. Individuals with a learning disability demonstrated weaker auditory working memory than individuals in either the attention-deficit/hyperactivity or clinical control groups.

    Ahmet Evlice


    Material and Methods: Between 2014-2016 years; mini mental state examination, forward and backward digit span, verbal fluency (semantic and lexical, clock drawing, verbal and visual memory tests were performed to healthy people. The presence of correlation between neuropsychological tests and gender, age and education were researched in healthy people. Results: Hundred subjects (60 female, 40 male were included to study. No difference was observed between male and female subjects on neuropsychological tests. There was negative correlation between age and mini mental state examination, digit span and semantic fluency tests. And also there was positive correlation between education and all neuropsychological tests (except verbal memory test. Conclusion: The mean neuropsychological test scores in healthy people were not shown differences by gender, but they were affected by age and education. [Cukurova Med J 2016; 41(3.000: 528-532

  7. Neuropsychological syndromes associated with Alzheimer's/vascular dementia: a latent class analysis. (United States)

    Epidemiologic autopsy studies show mixed Alzheimer's disease (AD)/vascular pathology in many patients. Moreover, clinical research shows that it is not uncommon for AD and vascular dementia (VaD) patients to be equally impaired on memory, executive, or other neurocognitive tests. However, this clinical heterogeneity has not been incorporated into the new diagnostic criteria for AD (Dubois et al., 2010; McKhann et al., 2011). The current research applied Latent Class Analysis (LCA) to a protocol of six neuropsychological parameters to identify phenotypic subtypes from a large group of AD/VaD participants. Follow-up analyses examined difference between groups on neuroradiological parameters and neuropsychological measures of process and errors. 223 AD/VaD patients were administered a comprehensive neuropsychological protocol. Measures of whole brain and hippocampal volume were available for a portion of the sample (n = 76). LCA identified four distinct groups: moderate/mixed dementia (n = 54; 24.21%), mild/mixed dementia (n = 91; 40.80%); dysexecutive (n = 49, 21.97%), and amnestic (n = 29, 13.00%). Follow-up analyses comparing the groups on neuropsychological process and error scores showed that the dysexecutive group exhibited difficulty sustaining mental set. The moderate/mixed group evidenced pronounced impairment on tests of lexical retrieval/naming along with significant amnesia. Amnestic patients also presented with gross amnesia, but showed relative sparing on other neuropsychological measures. Mild/mixed patients exhibited milder memory deficits that were intermediary between the amnestic and moderate/mixed groups. There are distinct neuropsychological profiles in patients independent of clinical diagnosis, suggesting that the two are not wholly separate and that this information should be integrated into new AD diagnostic paradigms.

  8. Assessing Executive Dysfunction in Neurodegenerative Disorders: A Critical Review of Brief Neuropsychological Tools

    Directory of Open Access Journals (Sweden)

    Helena S. Moreira


    Full Text Available Executive function (EF has been defined as a multifaceted construct that involves a variety of high-level cognitive abilities such as planning, working memory, mental flexibility, and inhibition. Being able to identify deficits in EF is important for the diagnosis and monitoring of several neurodegenerative disorders, and thus their assessment is a topic of much debate. In particular, there has been a growing interest in the development of neuropsychological screening tools that can potentially provide a reliable quick measure of EF. In this review, we critically discuss the four screening tools of EF currently available in the literature: Executive Interview-25 (EXIT 25, Frontal Assessment Battery (FAB, INECO Frontal Screening (IFS, and FRONTIER Executive Screen (FES. We first describe their features, and then evaluate their psychometric properties, the existing evidence on their neural correlates, and the empirical work that has been conducted in clinical populations. We conclude that the four screening tools generally present appropriate psychometric properties, and are sensitive to impairments in EF in several neurodegenerative conditions. However, more research will be needed mostly with respect to normative data and neural correlates, and to determine the extent to which these tools add specific information to the one provided by global cognition screening tests. More research directly comparing the available tools with each other will also be important to establish in which conditions each of them can be most useful.

  10. Neuropsychological functioning related to specific characteristics of nocturnal enuresis. (United States)

    Van Herzeele, C; Dhondt, K; Roels, S P; Raes, A; Groen, L-A; Hoebeke, P; Walle, J Vande


    There is a high comorbidity demonstrated in the literature between nocturnal enuresis and several neuropsychological dysfunctions, with special emphasis on attention deficit hyperactivity disorder (ADHD). However, the majority of the psychological studies did not include full non-invasive screening and failed to differentiate between monosymptomatic nocturnal enuresis (MNE) and non-MNE patients. The present study primarily aimed to investigate the association between nocturnal enuresis and (neuro)psychological functioning in a selective homogeneous patient group, namely: children with MNE and associated nocturnal polyuria (NP). Secondly, the study investigated the association between specific characteristics of nocturnal enuresis (maximum voided volume, number of wet nights and number of nights with NP) and ADHD-inattentive symptoms, executive functioning and quality of life. The psychological measurements were multi-informant (parents, children and teachers) and multi-method (questionnaires, clinical interviews and neuropsychological testing). Thirty children aged 6-16 years (mean 10.43 years, SD 3.08) were included. Of them, 80% had at least one psychological, motor or neurological difficulty. The comorbid diagnosis of ADHD, especially the predominantly inattentive presentation, was most common. According to the teachers, a low maximum voided volume (corrected for age) was associated with more attention problems, and a high number of nights with NP was associated with more behaviour-regulation problems. No significant correlations were found between specific characteristics of enuresis and quality of life. Details are demonstrated in Table. The children were recruited from a tertiary referral centre, which resulted in selection bias. Moreover, NP was defined as a urine output exceeding 100% of the expected bladder capacity for age (EBC), and not according to the expert-opinion-based International Children's Continence Society norm of 130% of EBC.

    Özcan, Kemal; Özcan, Özlem; Muluk, Nuray Bayar; Cingi, Cemal; Durukan, Kübra


    We aimed to evaluate the relationship between attention-deficit/hyperactivity disorder (ADHD) and self-inserted foreign bodies (SIFBs) in children by the Conners' Parent Rating Scales-Revised (CPRS-R). Forty-five children (31 males and 14 females) with self-inserted foreign body of ear/nose and 37 healthy children (22 males and 15 females) included into the study. They were all between 3 and 9 years old. The parents filled the socio-demographic information form including age, gender, demographic data, previous medical history of the child and features of the family; and completed the Conners' Parent Rating Scales-Revised (CPRS-R) questionnaire. In the SIFB group (study), 55.6% of the children were not attending to the school, 31.1% of them were attending to the primary school and 13.3% of them were the pre-school student. These rates were 37.8%, 32.4% and 29.7%, respectively, in the control group. The all CPRS-R subscale values (CG/I, H, ADHD-I, CGI-DI, DSMIV SS-I, DSM-IV SS-HI and DSM-IV SS-T) were significantly higher in the study group than the control group. There was no significant correlation between gender of the children and CPRS-R subscales. Children with lower school success, and having previous psychiatric problems were related to higher CPRS-R values in all subscales. In older children, hyperactivity scores were lower; and in younger children and the children, not going to the school, hyperactivity scores were higher. CPRS-R scores decreased as the child grown. It was concluded that children with ADHD were more likely to have conditions that might damage himself/herself such as self-inserted foreign body or trauma than normal children. To avoid this condition, these families should closely observe the child; and the child should be provided to participate in activities such as group games and activities that contribute to the development of the child. Warning the children properly and close follow-up of the young children are required to prevent this

    We investigate the association between temperament and character dimensions, on the one hand,and computerised neuropsychological test performance, on the other hand. Temperament and character dimensions were operationalised as scores on the subscales of the Temperament and Character Inventory (TCI), a 240-item measure that is based on the psychobiological theory of personality. Neuropsychological outcomes were measured on six computerised tests of executive functioning and abstract reasoning ...

  13. Clinical neuropsychology practice and training in Canada. (United States)

    Janzen, Laura A; Guger, Sharon


    This invited paper provides information about professional neuropsychology issues in Canada and is part of a special issue addressing international perspectives on education, training, and practice in clinical neuropsychology. Information was gathered from literature searches and personal communication with other neuropsychologists in Canada. Canada has a rich neuropsychological history. Neuropsychologists typically have doctoral-level education including relevant coursework and supervised practical experience. Licensure requirements vary across the 10 provinces and there are regional differences in salary. While training at the graduate and internship level mirrors that of our American colleagues, completion of a two-year postdoctoral fellowship in neuropsychology is not required to obtain employment in many settings and there are few postdoctoral training programs in this country. The majority of neuropsychologists are employed in institutional settings (e.g. hospitals, universities, rehabilitation facilities), with a growing number entering private practice or other settings. There are challenges in providing neuropsychological services to the diverse Canadian population and a need for assessment measures and normative data in multiple languages. Canadian neuropsychologists face important challenges in defining ourselves as distinct from other professions and other psychologists, in maintaining funding for high-quality training and research, in establishing neuropsychology-specific training and practice standards at the provincial or national level, and ensuring the clinical care that we provide is efficient and effective in meeting the needs of our patient populations and consumers, both within and outside of the publically funded health care system.

  14. Providing effective supervision in clinical neuropsychology. (United States)

    Stucky, Kirk J; Bush, Shane; Donders, Jacobus


    A specialty like clinical neuropsychology is shaped by its selection of trainees, educational standards, expected competencies, and the structure of its training programs. The development of individual competency in this specialty is dependent to a considerable degree on the provision of competent supervision to its trainees. In clinical neuropsychology, as in other areas of professional health-service psychology, supervision is the most frequently used method for teaching a variety of skills, including assessment, report writing, differential diagnosis, and treatment. Although much has been written about the provision of quality supervision in clinical and counseling psychology, very little published guidance is available regarding the teaching and provision of supervision in clinical neuropsychology. The primary focus of this article is to provide a framework and guidance for the development of suggested competency standards for training of neuropsychological supervisors, particularly at the residency level. In this paper we outline important components of supervision for neuropsychology trainees and suggest ways in which clinicians can prepare for supervisory roles. Similar to Falender and Shafranske (2004), we propose a competency-based approach to supervision that advocates for a science-informed, formalized, and objective process that clearly delineates the competencies required for good supervisory practice. As much as possible, supervisory competencies are related to foundational and functional competencies in professional psychology, as well as recent legislative initiatives mandating training in supervision. It is our hope that this article will foster further discussion regarding this complex topic, and eventually enhance training in clinical neuropsychology.

    Full Text Available Objective: to evaluate the cerebral circulation in idiopathic arterial hypotension (IAH in relation to neurological and neuropsychological disorders. Patients and methods. Sixty-five patients (mean age 40.2 [8, 14] years with prolonged IAH were examined. Neuropsychological examination was made using the procedure adapted by A.R. Luria; different psychic functions (memory, speech, gnosis, praxis, thinking, attention, counting, writing, and reading were studied. Cerebral hemodynamics was investigated using duplex scanning of the brachiocephalic arteries (BCA, middle cerebral arteries (MCA, internal jugular (IJV and vertebral veins (VV. The patients were assigned to 2 groups: 1 19 (29% patients with somatoform disorders, 2 46 (71% patients with signs of the initial manifestations of chronic cerebrovascular insufficiency. Group 2 patients were older and had a longer history of IAH. Results. In all the patients, cerebral blood supply in the carotid system showed moderately lower arterial blood inflow with a compensatory vascular resistance decrease and balanced venous outflow reduction with increased vascular resistance. Group 2 patients had a substantial (to the lower normal range blood flow decline in the vertebral artery along with increased peripheral resistance in the VV. The degree of neuropsychological derangement was inversely proportional to blood flow velocity in BCA and MCA and to blood outflow in IJV and VV.

    Full Text Available Progressive muscular atrophy (PMA is a rare type of degenerative motor neuron disease (MND of which the onset happens in adult period. Despite its well-defined clinical characteristics, its neuropsychological profile has remained poorly understood, considering the consensus of cognitive and behavioral impairment reached in amyotrophic lateral sclerosis (ALS.We conducted a cross-sectional evaluation of Chinese PMA patients with a series of comprehensive batteries emphasizing the executive and attention function, and covering other domains of memory, language, visuospatial function, calculation and behavior as well. Their performances were compared with those of age- and education-matched ALS and healthy controls (HC.21 patients newly diagnosed with PMA were consecutively enrolled into our ALS and other MND registry platform, accounting for 14.7% of all the incident MND cases registered during the same period. 20 patients who completed the neuropsychological batteries were included into analysis. Compared with HC, PMA performed significantly worse in maintenance function of attention, while they exhibited quantitative similarity to ALS in all behavioral inventories and neuropsychological tests except the time for Stroop interference effect.PMA could display mild cognitive dysfunction in the same frontal-mediated territory of ALS but in a lesser degree, whereas they did not differ from ALS behaviorally.

  17. Psychomotor Retardation, Attention Deficit and Executive Dysfunctional in Young Non-hospitalised Un-medicated Non-psychotic Unipolar Depression Patients. (United States)

    Ilamkar, Kamini Ramdas


    Neuropsychological deficits have been reported in patients with Major Depressive Disorder (MDD) during an acute episode. The reaction time gives an idea about integrity and the processing ability of central nervous system. The simple reaction time task is an attention seeking task that focuses primarily on speed of processing (executive function). Psychomotor retardation (i.e., delay at the output which includes perceptual decision, planning, motor process) is a constant and probably central feature of depression. The purpose of present study was to evaluate the neuropsychological functioning in young non-hospitalised un-medicated non-psychotic unipolar depression by focusing on tasks related to prefrontal cortex functioning. Newly diagnosed young antidepressant-free, clinically depressed patients (20 males and 24 females, n=44) and healthy controls (24 males and 27 females, n=51) pair-wise matched on gender, age (mean age 25±4) were included in this study. All patients were diagnosed with major depressive episode according to Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). Both the patients and healthy controls performed a simple reaction time task with components of alerting auditory and visual orientation of attention by an instrument response analyzer. Statistical Analysis : The performances were expressed in mean ± standard deviation of the reaction time by using the Student's unpaired t-test. Patients with unipolar depression relative to controls were impaired on psychomotor performance and deficits in sustained attention remained significant. These findings suggest deficits in sustained attention as vulnerability marker for unipolar depression. With further methodologically sound research, the changes in neuropsychological function associated with treatment response may provide a means of evaluating different treatment strategies in major depression.

  19. Neuropsychological rehabilitation in a patient with ruptured anterior communicating artery aneurysm: 48 month outcomes

    Directory of Open Access Journals (Sweden)

    Silvia A. Prado Bolognani

    Full Text Available Abstract The neurobehavioral impairments associated with aneurysms of the anterior communicating artery (ACoA are severe amnesia, executive problems and personality changes. Although most patients achieve a favorable neurological outcome, those cognitive deficits usually prevent return to previous activities and levels of social integration. Objectives: To report the outcomes of a neuropsychological and behavioral intervention in a 55 year-old man with very severe memory and executive dysfunctions following ACoA aneurysm rupture. Methods: Neuropsychological intervention focused in functional adjustment in everyday life was used, including individual sessions with the patient, discussion sessions with caregivers and also work with patient at home, aiming generalization of the rehabilitation strategies. Neuropsychological and functional assessments were conducted pre and post intervention. Results: Important improvements were seeing in behavior and daily living performance after treatment. Conclusions: A neuropsychological rehabilitation approach focused on goals based on the family and caregivers necessities is an efficient manner in which to carry out cognitive rehabilitation in severe cases. The importance of a supportive family should be stressed.

  1. Neuropsychology of perpetrators of domestic violence: the role of traumatic brain injury and alcohol abuse and/or dependence. (United States)

    Romero-Martínez, Ángel; Moya-Albiol, Luis


    Neuropsychological impairments of the executive functions, memory, attention, intelligence quotient, and empathy have been found in perpetrators of domestic violence (intimate partner violence). These impairments could be partially explained by alcohol abuse, dependence, or traumatic brain injuries. This study reviews the neuropsychological deficits of perpetrators of intimate partner violence. At the same it seeks to integrate and relate these main points with their neuroanatomical correlates. We have also established the relationship between alcohol abuse, dependence, brain damage (including traumatic brain injuries) and those deficits. Scientific literature has been reviewed by means of Google Scholar, PsycINFO, PubMed, Medline and ISI Web of Knowledge. Perpetrators of domestic violence present high mental rigidity, as well as low levels of inhibition, processing speed, verbal and attention skills, and abstract reasoning. Additionally, perpetrators show working and long play memory impairments. Moreover, those deficits could be impaired by traumatic brain injuries and alcohol abuse and/or dependence. Nonetheless, these both variables are not enough to explain the deficits. Functional abnormalities on the prefrontal and occipital cortex, fusiform gyrus, posterior cingulate gyrus, hippocampus, thalamus and amygdala could be associated with these impairments. An analysis of these mechanisms may assist in the development of neuropsychological rehabilitation programmes that could help improve current therapies.

  2. Neuropsychological Function in Patients With Acute Tetraplegia and Sleep Disordered Breathing. (United States)

    Schembri, Rachel; Spong, Jo; Graco, Marnie; Berlowitz, David J


    To investigate the relationship between apnea severity and neuropsychological function in patients with acute-onset tetraplegia and sleep disordered breathing. Polysomnography and neuropsychological testing were performed on 104 participants (age M = 45.60, SD = 16.38; 10 female) across 11 international sites, 2 months postinjury (M = 60.70 days, SD = 39.48). Neuropsychological tests assessed attention, information processing, executive function, memory, learning, mood, and quality of life. More severe sleep apnea was associated with poorer attention, information processing, and immediate recall. Deficits did not extend to memory. Higher preinjury intelligence and being younger reduced the associations with sleep disordered breathing; however, these protective factors were insufficient to counter the damage to attention, immediate recall, and information processing associated with sleep disordered breathing. These data suggest that new spinal cord injury may function as a model of "acute sleep apnea" and that more widespread sleep apnea-related deficits, including memory, may only be seen with longer exposure to apnea. These findings have important implications for functioning and skill acquisition during rehabilitation and, as such, highlight the importance of sleep health following tetraplegia.

  3. A preliminary validity study of the cambridge neuropsychological test automated battery for the assessment of executive function in schizophrenia and bipolar disorder. (United States)

    Kim, Hee Sun; An, Yong Min; Kwon, Jun Soo; Shin, Min-Sup


    Although the executive function subtests of the Cambridge Neuropsychological Test Automated Battery (CANTAB) have been used to assess cognitive function in diverse psychiatric illnesses, few studies have verified the validity of this battery for Korean psychiatric patients. Therefore, this preliminary study evaluated the construct and concurrent validity of the executive function subtests of the CANTAB for Korean psychiatric patients by comparing it with subtests of the Computerized Neuropsychological Test (CNT). Three subtests of the CANTAB and three subtests of the CNT were administered to 36 patients diagnosed with either schizophrenia or bipolar disorder. Subtests of the CANTAB included the Intra/Extra-Dimensional Set Shift (IED), Stockings of Cambridge (SOC), and Spatial Working Memory (SWM). Differences between groups on each subtest as well as correlations between the subtests of the CANTAB and the CNT were assessed. The schizophrenia group performed significantly more poorly on the IED and the Wisconsin Card Sorting Test (WCST) compared with the bipolar disorder group. Additionally, correlation analyses revealed a significant correlation between the IED and the WCST; a positive correlation between the SOC and the Trail Making Test, Part B and the Stroop test; and a significant correlation between the SWM and the Stroop test. This study verified the construct and concurrent validity of the executive function subtests of the CANTAB for Korean psychiatric patients and suggests that the subtests of this battery would be useful and appropriate for assessing deficits in executive function in Korean clinical settings.

  4. [Neuropsychological data about children with autistic disorder and an intellectual development within what is considered to be a normal span of time]. (United States)

    Carvajal-Molina, F; Alcamí-Pertejo, M; Peral-Guerra, M; Vidriales-Fernández, R; Martín-Plasencia, P

    Characteristic symptoms of autistic disorder (AD) can be the result of cognitive impairment which can be produced by specific neurological irregularities. Up until now a specific cognitive deficit in autism has not been found, although the majority of people with autism show intellectual impairment, verbal scores lower than manipulative measures and executive dysfunctions. A neuropsychological evaluation of children with AD was planned. These children had intellectual abilities in the normal range. They were compared with two other groups, one with pervasive developmental disorder not otherwise specified (PDD-NS), and the other from the general population. A battery of neuropsychological tests was carried out on five boys AD, five boys PDD-NS, and five boys of the general population. All of them were between 9 and 15 years old and their intellectual abilities were within the normal range. The children AD obtained verbal scores lower than their visual-perception scores. They also showed good dynamic coordination of movement. Scores in episodic memory tasks where executive strategies are needed were low. The characteristics described in the paper do not demonstrate a specific profile of the AD, but they can be useful in diagnoses and in planning treatment.

  5. Misconceptions on neuropsychological rehabilitation and traumatic brain injury.

    Alberto García- Molina


    Full Text Available There are many misconceptions about traumatic brain injuries, their recovery and outcome; misconceptions that have their origin in a lack of information influenced by the image that the media show of the brain damage. Development. Based on clinical experience, the authors of this essay sets out his personal view on some of the most frequent misconceptions in the field of neuropsychological rehabilitation of traumatic brain injury: 1 All deficits are evident; 2 The recovery depends mainly on the involvement of the patient: more effort, more rapid recovery; 3 Two years after traumatic brain injury there is no possibility of improvement and recovery; and 4 The “miracle” of recovery will occur when is found the appropriate professional or treatment. These and other beliefs may influence directly or indirectly on the recovery process and the expectations placed on it by the families and patients. Conclusions. Provide accurate, clear and honest information, at the right time, helps patients and their families to better understand the deficits, the course of recovery and to adapt to the new reality resulting from a traumatic brain injury.

  6. A neurodevelopmental approach to understanding memory processes among intellectually gifted youth with attention-deficit hyperactivity disorder. (United States)

    Whitaker, Ashley M; Bell, Terece S; Houskamp, Beth M; O'Callaghan, Erin T


    Intellectual giftedness is associated with strong strategic verbal memory while attention-deficit hyperactivity disorder (ADHD) is associated with strategic verbal memory deficits; however, no previous research has explored how this contradiction manifests in gifted populations with diagnoses of ADHD. The purpose of this study was to explore strategic verbal memory processes among intellectually gifted youth with and without ADHD to provide clarification regarding this specific aspect of neuropsychological functioning within this population. One hundred twenty-five youth completed neuropsychological evaluations including the Wechsler Intelligence Scale for Children-Fourth Edition and California Verbal Learning Test-Children's Version (CVLT-C). Results revealed significant differences between groups, with intellectually gifted youth with ADHD achieving lower T scores on CVLT-C Trials 1 through 5 compared with intellectually gifted youth without ADHD, and intellectually gifted youth with ADHD achieving higher T scores than youth of average intellectual abilities with ADHD. Additionally, repeated-measures analysis of variance revealed a main effect improvement among gifted youth with ADHD in short-delay recall when provided with organizational cues. Findings revealed new evidence about the role of twice exceptionality (specifically intellectual giftedness and ADHD) in strategic verbal memory and have important implications for parents, educators, psychologists and neuropsychologists, and other mental health professionals working with this population.

  7. Beyond the numbers: expanding the boundaries of neuropsychology. (United States)

    Perry, William


    Beyond the Numbers: Expanding the Boundaries of Neuropsychology was Dr Perry's 2007 presidential address in the annual conference of the National Academy of Neuropsychology. In his address he discussed the achievements of the science of neuropsychology and highlighted some areas that exemplified the expansion of the boundaries of neuropsychology. These areas are: (i) the study of neuropsychological functioning in new or non-traditional populations, particularly seemingly healthy people and people with non-brain diseases; (ii) the interface of cognition and genetics; (iii) the use of the process approach as a means of understanding brain functioning; and (iv) a translational application to the science of neuropsychology.

  8. Using neuropsychological and personality tests to assess the likelihood of patient employment. (United States)

    Heaton, R K; Chelune, G J; Lehman, R A


    This study assessed the ability deficits and personality disturbances associated with three levels of employment in patients referred for neuropsychological testing. Highly significant group differences were found, with the unemployed group consistently showing greatest pathology on the tests, the full time employed group performing relatively normally, and the part time employed group earning intermediate scores. A discriminant function which used both neuropsychological and personality measures was found to discriminate unemployed from full time employed patients satisfactorily. Classification rates achieved by the function for validation and cross-validation samples support its clinical utility in identifying new patients who are at high risk for unemployment. It appears that psychological tests commonly used in neurological and psychiatric diagnosis can also help predict some aspects of patients' abilities to function in everyday life.

  9. Neuropsychological and Emotional Correlates Involved in Cocaine Use: A Theoretical Review of New Findings

    Directory of Open Access Journals (Sweden)

    Juan Ramos-Cejudo


    Full Text Available Cocaine is being an alarming health problem in developed countries. This issue has important implications in economic, social and public health. Currently, efforts are focused on research in metabolic, neuropsychological and emotional changes, resulting from chronic use. However, theoretical work review on this critical area is not available. The aim of our study is to review and integrate the ultimate findings and results in terms of metabolic abnormalities, neuropsychological and emotional abuse of cocaine. The results show a significant impairment of dopaminergic pathways in the frontal lobe, both in the number of recipient and depletion of the neurotransmitter, as well as an important executive function deficit in response inhibition in attention and working memory. In addition, alterations in the ability in identifying emotions, impulsiveness, decision making, anxiety and depression are proved in different studies.

  10. Post-traumatic stress disorder, dissociation, and neuropsychological performance in Latina victims of childhood sexual abuse. (United States)

    Rivera-Vélez, Giselle M; González-Viruet, Maribella; Martínez-Taboas, Alfonso; Pérez-Mojica, Deborah


    This study compared the memory, attention/concentration, and executive functioning of 12 women with histories of child sexual abuse with a control group of 12 women without childhood abuse. Participants completed a neuropsychological test battery and various instruments assessing post-traumatic stress disorder and dissociation. The child sexual abuse group had lower performance than the control group on long- and short-term visual and verbal memory and presented more limited performance on executive functioning tasks. Functioning in these areas showed a negative correlation with post-traumatic stress disorder and dissociative symptoms. These findings suggest that child sexual abuse is associated with memory and executive functioning deficits and supports the idea that people with trauma histories and increased post-traumatic stress disorder and dissociation symptoms may have alterations in neuropsychological functioning.

  11. The Neuropsychological Function of Older First-Time Child Exploitation Material Offenders: A Pilot Study. (United States)

    Rodriguez, Marcelo; Ellis, Andrew


    Despite the growing incidence of child exploitation offences, there is little knowledge of the neuropsychological function of older child exploitation material offenders (CEMOs). Given that studies have reported that sex offenders demonstrate deficits attributed to frontal and temporal lobe function, the aim of this pilot study was to investigate the frontotemporal function of older first-time child exploitation material offenders (FTCEMOs). The neuropsychological performance of 11 older FTCEMOs was compared with 34 older historical sex offenders (HSOs) and 32 older nonsex offender (NSO) controls. Forty-five percent of FTCEMOs admitted to a pedophilic interest, which was significantly lower than those reported by HSOs. FTCEMOs provided significantly higher intellectual function scores than HSOs. Results revealed no evidence of mild or major neurocognitive disorder in FTCEMOs. Although the groups were not significantly different, compared with normative data, FTCEMOs reported a high incidence of impairment on a measure of decision making and on a measure of facial emotional recognition.

    Jak, Amy J; Gregory, Amber; Orff, Henry J; Colón, Candice; Steele, Norma; Schiehser, Dawn M; Delano-Wood, Lisa; Jurick, Sarah M; Twamley, Elizabeth W


    Clinical neuropsychological presentation of treatment-seeking Veterans with a remote history of mild traumatic brain injury (mTBI) is widely variable. This manuscript seeks to better characterize cognitive concerns in the post-acute phase following mTBI and to identify the neuropsychological profiles of a large sample of clinically referred Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn (OEF/OIF/OND) Veterans with a history of mTBI and current cognitive complaints. We hypothesized that a minority of cases would exhibit valid and widespread neuropsychological deficits. Retrospective chart reviews of neuropsychological testing and mental health symptoms and diagnoses were conducted on 411 clinically referred OEF/OIF/OND Veterans with a history of mTBI. Groups were created based on scores on performance validity measures and based on overall neuropsychological performance. A total of 29.9% of the sample performed below normative expectations on at least one performance validity test (PVT). Of those Veterans performing adequately on PVTs, 60% performed within normal limits on virtually all neuropsychological measures administered, leaving only 40% performing below expectations on two or more measures. Mood and neurobehavioral symptoms were significantly elevated in Veterans performing below cutoff on PVTs compared to Veterans who performed within normative expectations or those with valid deficits. Neurobehavioral symptoms were significantly correlated with mental health symptom reports but not with injury variables. In summary, in a large sample of clinically referred Veterans with persistent cognitive complaints after mild TBI, a third demonstrated invalid clinical neuropsychological testing, and, of those performing at or above cutoff on PVTs, over half performed within normative expectations across most neuropsychological tests administered. Results highlight the importance of objective assessment of cognitive functioning in this population

  13. Neuropsychological performance in schizotypal personality disorder: importance of working memory. (United States)

    Mitropoulou, Vivian; Harvey, Phillip D; Zegarelli, Gayle; New, Antonia S; Silverman, Jeremy M; Siever, Larry J


    Cognitive deficits consistently have been reported in schizophrenia patients and in patients with schizotypal personality disorder. For this study, the authors wanted to identify which of the domains of cognitive impairment represent "core" deficits of schizophrenia, comparing subjects with schizotypal personality disorder to two comparison groups: healthy volunteers and patients with personality disorders unrelated to schizophrenia. Three groups completed a neuropsychological battery: patients with DSM-III-R schizotypal personality disorder (N=82); patients with DSM-III-R personality disorders unrelated to schizophrenia (i.e., a personality disorder other than schizotypal, schizoid, or paranoid [N=44]); and healthy volunteers (N=63). The battery included the California Verbal Learning Test, Trailmaking Test parts A and B, the Dot test of working memory, the Stroop Color and Word Test, the Paced Auditory Serial Addition Test, the WMS visual reproduction test, and the WAIS-R vocabulary and block design. Normative standards for performance that controlled for age, gender, and education were created from the scores of the healthy volunteers. Overall, schizotypal personality disorder patients performed significantly worse than the healthy volunteers and those with personality disorders unrelated to schizophrenia. Specifically, patients with schizotypal personality disorder demonstrated impaired performance on the Paced Auditory Serial Addition Test, WMS visual reproduction test, Dot test, and California Verbal Learning Test. In addition, in a regression analysis, performance on the Paced Auditory Serial Addition Test demonstrated the largest effect size. Indeed, it accounted for unique variance above and beyond all other cognitive measures, since controlling for Paced Auditory Serial Addition Test performance abolished group differences across all other measures. Patients with schizotypal personality disorder demonstrated moderate cognitive impairment compared with

  14. Authentic professional competence in clinical neuropsychology. (United States)

    Denney, Robert L


    Authentic Professional Competence in Clinical Neuropsychology was Dr Denney's 2009 presidential address at the Annual Conference of the National Academy of Neuropsychology. In his address, he highlighted the need for clinical neuropsychologists to strive for authentic professional competence rather than a mere pretense of expertise. Undisputed credibility arises from authentic professional competence. Achieving authentic professional competence includes the completion of a thorough course of training within the defined specialty area and validation of expertise by one's peers through the board certification process. Included in the address were survey results regarding what the consumer believes about board certification as well as survey results regarding the experiences of recent neuropsychology diplomates. It is important for neuropsychologists to realize that the board certification process enhances public perception and credibility of the field as well as personal growth for the neuropsychologist. Lastly, he urged all neuropsychologists to support the unified training model and pursue board certification.

  15. Uncovering a clinical portrait of sluggish cognitive tempo within an evaluation for attention-deficit/hyperactivity disorder: A case study. (United States)

    Becker, Stephen P; Ciesielski, Heather A; Rood, Jennifer E; Froehlich, Tanya E; Garner, Annie A; Tamm, Leanne; Epstein, Jeffery N


    Despite the burgeoning scientific literature examining the sluggish cognitive tempo (SCT) construct, very little is known about the clinical presentation of SCT. In clinical cases where SCT is suspected, it is critical to carefully assess not only for attention-deficit/hyperactivity disorder (ADHD) but also for other comorbidities that may account for the SCT-related behaviors, especially internalizing symptoms and sleep problems. The current case study provides a clinical description of SCT in a 7-year-old girl, offering a real-life portrait of SCT while also providing an opportunity to qualitatively differentiate between SCT and ADHD, other psychopathologies (e.g. depression, anxiety), and potentially related domains of functioning (e.g. sleep, executive functioning [EF]). "Jessica" was described by herself, parents, and teacher as being much slower than her peers in completing schoolwork, despite standardized testing showing Jessica to have above average intelligence and academic achievement. Jessica's parents completed rating scales indicating high levels of SCT symptoms and daytime sleepiness, as well as mildly elevated EF deficits. More research is needed to determine how to best conceptualize, assess, and treat SCT, and Jessica's case underscores the importance of further work in this area. © The Author(s) 2014.

  17. Pb Neurotoxicity: Neuropsychological Effects of Lead Toxicity

    Directory of Open Access Journals (Sweden)

    Lisa H. Mason


    Full Text Available Neurotoxicity is a term used to describe neurophysiological changes caused by exposure to toxic agents. Such exposure can result in neurocognitive symptoms and/or psychiatric disturbances. Common toxic agents include heavy metals, drugs, organophosphates, bacterial, and animal neurotoxins. Among heavy metal exposures, lead exposure is one of the most common exposures that can lead to significant neuropsychological and functional decline in humans. In this review, neurotoxic lead exposure's pathophysiology, etiology, and epidemiology are explored. In addition, commonly associated neuropsychological difficulties in intelligence, memory, executive functioning, attention, processing speed, language, visuospatial skills, motor skills, and affect/mood are explored.

  18. Neuropsychological characteristics of five children with the Landau-Kleffner syndrome: dissociation of auditory and phonological discrimination. (United States)

    Korkman, M; Granström, M L; Appelqvist, K; Liukkonen, E


    The Landau-Kleffner Syndrome (LKS) is characterized by acquired receptive aphasia and EEG abnormality with onset between the ages of 3 and 8 years. This study presents neuropsychological assessments in 5 children with LKS. The aims were (1) to specify the neuropsychological deficits characteristic of these children; and (2) to clarify the nature of the receptive aphasia by comparing nonverbal and verbal auditory discrimination. Receptive aphasia was present in all children. Retardation, poor motor coordination, hyperkinesia, and conduct problems were frequent but variable. All children exhibited a dissociation between the discrimination of environmental sounds and phonological auditory discrimination, the latter being more impaired than the former. This suggests that the primary deficit of the receptive aphasia is an impairment of auditory phonological discrimination rather than a generalized auditory agnosia.

    Early detection and prospective evaluation of clinical high-risk (CHR) individuals who may develop schizophrenia or other psychotic disorders is critical for predicting psychosis onset and for testing preventive interventions. To elucidate the neuropsychology of the CHR syndrome, to determine the association of neuropsychological function with conversion to psychosis and family history of psychosis, and to examine whether baseline neuropsychological functioning predicts subsequent psychosis. Longitudinal study with 2(1/2) years of follow-up. Eight centers participating in the North American Prodrome Longitudinal Study. Three hundred four prospectively identified CHR individuals meeting Structured Interview for Prodromal Syndromes criteria, 52 non-CHR persons with a family history of psychosis in first- or second-degree relatives (family high-risk group), and 193 normal controls with neither a family history of psychosis nor a CHR syndrome, all of whom underwent baseline neuropsychological evaluations. A neurocognitive composite score, 8 individual neuropsychological measures, an IQ estimate, and high-risk status. Global ("composite") neuropsychological functioning was comparably impaired in the CHR and family high-risk groups compared with controls, but profiles differed significantly between groups. Neuropsychological functioning in the CHR group was significantly lower in persons who progressed to psychosis than in those who did not and was worst in the subgroup with a family history of psychosis. Tests of processing speed and verbal learning and memory were most sensitive in discriminating CHR individuals from controls, although reductions were less severe than in established schizophrenia. Neuropsychological functioning did not contribute uniquely to the prediction of psychosis beyond clinical criteria, but worse verbal memory predicted more rapid conversion. These findings document that CHR individuals have significant neuropsychological difficulties

  20. Neuropsychology, neuroimaging or motor phenotype in diagnosis of Parkinson's disease-dementia: which matters most? (United States)

    Di Biasio, Francesca; Vanacore, Nicola; Fasano, Alfonso; Modugno, Nicola; Gandolfi, Barbara; Lena, Francesco; Grillea, Giovanni; Pietracupa, Sara; Caranci, Giovanni; Ruggieri, Stefano


    Parkinson's disease (PD) is a neurodegenerative disorder affecting not only the motor system but also the cognitive and behavioral domains. Although there are many studies addressing the issue of cognition, a universally recognized method to diagnose patients with dementia is still lacking. The aim of this study was to determine which neuropsychological test is the most reliable in the diagnosis of dementia in PD and to establish if mini mental state examination (MMSE) is enough to detect this condition. We studied 200 consecutive PD patients through an extensive neuropsychological battery, clinical evaluation and brain magnetic resonance imaging over a period of 4 years. A logistic regression model was used to evaluate the interplay between possible risk factors and the accuracy of different neuropsychological tests. PD patients with dementia performed significantly worse in all the tests as compared to patients with PD alone: phonological verbal fluency, attentional matrices, Rey auditory verbal learning test and digit span were the most useful tools. Age and disease duration were correlated with cognitive impairment. No relevant differences were detected in phenotype, affected body side at onset, levodopa equivalent daily dose or neuroimaging findings (except for the occurrence of atrophy). Despite reasonable accuracy of MMSE (90%), its positive predictive value is only 74%. Using at least 3 neuropsychological tests, among those more significant detected with logistic regression analysis, the positive predictive value rises to 91%. In conclusion, the use of an extensive neuropsychological battery is still recommended in the diagnosis of dementia in PD. © Springer-Verlag 2011

    Bauer, Russell M; Iverson, Grant L; Cernich, Alison N; Binder, Laurence M; Ruff, Ronald M; Naugle, Richard I


    This joint position paper of the American Academy of Clinical Neuropsychology and the National Academy of Neuropsychology sets forth our position on appropriate standards and conventions for computerized neuropsychological assessment devices (CNADs). In this paper, we first define CNADs and distinguish them from examiner-administered neuropsychological instruments. We then set forth position statements on eight key issues relevant to the development and use of CNADs in the healthcare setting. These statements address (a) device marketing and performance claims made by developers of CNADs; (b) issues involved in appropriate end-users for administration and interpretation of CNADs; (c) technical (hardware/software/firmware) issues; (d) privacy, data security, identity verification, and testing environment; (e) psychometric development issues, especially reliability, and validity; (f) cultural, experiential, and disability factors affecting examinee interaction with CNADs; (g) use of computerized testing and reporting services; and (h) the need for checks on response validity and effort in the CNAD environment. This paper is intended to provide guidance for test developers and users of CNADs that will promote accurate and appropriate use of computerized tests in a way that maximizes clinical utility and minimizes risks of misuse. The positions taken in this paper are put forth with an eye toward balancing the need to make validated CNADs accessible to otherwise underserved patients with the need to ensure that such tests are developed and utilized competently, appropriately, and with due concern for patient welfare and quality of care.

  3. Neuropsychological Characteristics of Italian Children with Fetal Alcohol Spectrum Disorders (United States)

    Aragón, Alfredo S.; Coriale, Giovanna; Fiorentino, Daniela; Kalberg, Wendy O.; Buckley, David; Gossage, J. Phillip; Ceccanti, Mauro; Mitchell, Elisha R.; May, Philip A.


    Background Children with fetal alcohol spectrum disorders (FASD) display many problems ranging from deficits in intelligence to behavioral difficulties. Thus, many studies have aimed to better define the neuropsychological characteristics of children with FASD. The current article describes the neuropsychological characteristics of Italian children with severe diagnosis within FASD and compares them with controls. It was expected that intellectual functioning, language comprehension, academic skills, and inattention/hyperactivity would discriminate children with FASD from randomly-selected peers without FASD. Methods This paper presents data from a second cohort of children examined in 2005 as part of an in-school epidemiological study of FASD in Italy. Eighty children, 23 diagnosed with a FASD, and 57 randomly-selected control children from the same 1st grade classes, participated. After screening for FASD via growth and dysmorphology, the children were administered a test of general intelligence (WISC-R) as well as tests of nonverbal reasoning (Raven Colored Progressive Matrices), language comprehension (Rustioni), academic achievement (IPDA), and problem behavior (Disruptive Behavior Disorder Rating Scale). Results Children diagnosed with a FASD achieved lower scores than control children on Verbal, Performance, and Full Scale IQ. Profile analysis of the WISC-R indicates overall differences between the groups. However, some intact functioning within the FASD group was found, as the Similarities and Vocabulary subtests were similar to the controls. After an alpha adjustment to .004, the Block Design, Object Assembly, and Mazes subtests were significantly different from controls. On tests of nonverbal reasoning, language comprehension, and academic achievement, the children with a FASD scored significantly lower. Moreover, teachers rated children with a severe diagnosis within FASD as showing more inattentive symptoms than controls, while hyperactive

  4. Evaluation of feature extraction techniques on event-related potentials for detection of attention-deficit/hyperactivity disorder. (United States)

    Castro-Cabrera, P; Gomez-Garcia, J; Restrepo, F; Moscoso, O; Castellanos-Dominguez, G


    Event-related potentials (ERPs) are one of the most informative and dynamic methods of monitoring cognitive processes, which are widely used in clinical research to deal a variety of psychiatric and neurological disorders as attention-deficit/hyperactivity disorder (ADHD). This work proposes an extraction and selection methodology for discriminating between normal and pathological patients with ADHD by using ERPs. Three different sets of features (morphological, wavelets, and nonlinear based) are analyzed, looking for the best classification accuracy. The results show that the wavelet features provided a good discriminative capability, but it improved by combining all the set of features and applying a feature selection algorithm, reaching a maximum accuracy rate of 91.3%.

  5. Neuropsychological performance in patients with myasthenia gravis

    María Bárbara Eizaguirre


    Full Text Available Myasthenia gravis is a chronic autoimmune disease that affects the neuromuscular transmission. Controversial findings had been reported about cognitive impairment in this disease. The aim of this study was to investigate the cognitive pattern of patients with myasthenia gravis. There were enrolled 24 patients with myasthenia gravis, anti-acetylcholine receptor antibodies (ACRA positive, and 24 healthy controls. Patients: age 43.9 ± 14.8, years of education 10.9 ± 3.3. Controls: age 44.5 ± 15.4, years of education 11.5 ± 3.3. The following areas were evaluated: verbal memory: (long-term storage, retrieval, delayed recall of the Selective Remained Test; attention: Paced Auditory Serial Addition Task (PASAT 2 and 3 seconds; executive functions: analogies and numbers-letters sequence. Also, it was administered the Beck Depression Inventory II (BDI II. About 33.3% of patients obtained abnormal performance in two or more cognitive tests. 37.5% showed deterioration in attention; 33.3% in verbal memory; 29.2% in executive functions. Significant differences between patients and healthy controls were found in long-term storage (p = 0.001; retrieval (p = 0.007; delayed recall (p = 0.000; PASAT 3 (p = 0.009; PASAT 2 (p = 0.009 and analogies (p = 0.003. Evidence of depression was found: mild in 4.2% of patients; moderate in 25% and severe in 29.2%. Neuropsychological performance declines in patients with myasthenia gravis: attention was more affected than other cognitive areas

    The aim of this study is to assess the neuropsychological manifestations of mercury exposure in dentists. A cross-sectional study was carried out including 64 dentists matched to a control group according to age and gender. This study protocol included a neurological evaluation, a questionnaire assessing the study groups' general characteristics and personal factors that may affect mercury urinary excretion in both groups. EUROQUEST questionnaire and Hospital Anxiety and Depression scale (HADS) were used to evaluate the neuropsychological symptoms reported during the last 12 months. In both groups, mercury impregnation was assessed by monitoring urinary mercury. In the exposed group, scores of neurological symptoms, memory disturbances and anxiety were found to be significantly higher than those in controls (p mercury excretion in the exposed group. Mean levels of urinary mercury were significantly higher in the dentists group than in controls, with respective values of 21.1 ± 19.6 µg/g of creatinine and 0.05 ± 0.9 µg/g of creatinine. In nine dentists having urinary mercury levels higher than 35 µg/g of creatinine, neurological examination showed a bilateral and symmetric intentional tremor in both upper limbs. In the exposed group, the neuropsychological manifestations and levels of urinary mercury were found to be significantly correlated. Increased levels of urinary mercury observed in dentists suggest that exposure to mercury vapour emissions adversely affects dental professionals, therefore prevention measures should be strengthened, with a special medical supervision program of dentists exposed to mercury vapours should be implemented. We have also outlined some relevant patents in this article.

  10. The influence of handedness on the clinical presentation and neuropsychology of Alzheimer disease. (United States)

    Doody, R S; Vacca, J L; Massman, P J; Liao, T Y


    Research on the influence of handedness on the clinical presentation and neuropsychology of Alzheimer disease (AD) is scarce. To compare clinical presentation and neuropsychological test performance of right- and left-handed patients with AD. We hypothesized that left-handedness would be associated with younger onset, more rapid progression, and possibly cognitive hemispheric asymmetry. After determining handedness with the Edinburgh Inventory for Handedness for 922 patients with AD, 18 left-handed patients were compared with 18 right-handed patients matched individually on Mini-Mental State Examination scores, education, and age. We compared clinical characteristics (eg, age of onset), estimated rate of initial cognitive decline, language and visuospatial test performances, and patterns of cognitive and motor asymmetries for the 2 groups. Alzheimer's Disease Research Center at Baylor College of Medicine, Houston, Tex. Results of the Wechsler Adult Intelligence Scale-Revised verbal and performance IQ tests, the Western Aphasia Battery sequential commands subtest, the Boston Naming Test, the Halstead-Reitan Finger-Tapping Test, and the calculated Rate of Initial Progression. We found that left-handed patients had younger ages of onset but unexpectedly lower estimated rates of initial cognitive decline, and their results on language tests did not differ from those of right-handed patients. Regarding asymmetry, left-handed patients were more likely than right-handers to obtain lower verbal IQ than performance IQ scores and to exhibit faster finger-tapping speeds with their nondominant hand, but group differences did not attain statistical significance. There were disproportionately few left-handed patients with AD compared with population norms. Left-handed patients with AD do not differ from right-handed patients in the severity or pattern of neuropsychological deficits. Left-handedness or some factor associated with it may contribute to the early appearance of

    Full Text Available Abstract Background This study was realized thanks to the collaboration of children and adolescents who had been resected from cerebellar tumors. The medulloblastoma group (CE+, n = 7 in addition to surgery received radiation and chemotherapy. The astrocytoma group (CE, n = 13 did not receive additional treatments. Each clinical group was compared in their executive functioning with a paired control group (n = 12. The performances of the clinical groups with respect to controls were compared considering the tumor's localization (vermis or hemisphere and the affectation (or not of the dentate nucleus. Executive variables were correlated with the age at surgery, the time between surgery-evaluation and the resected volume. Methods The executive functioning was assessed by means of WCST, Complex Rey Figure, Controlled Oral Word Association Test (letter and animal categories, Digits span (WISC-R verbal scale and Stroop test. These tests are very sensitive to dorsolateral PFC and/or to medial frontal cortex functions. The scores for the non-verbal Raven IQ were also obtained. Direct scores were corrected by age and transformed in standard scores using normative data. The neuropsychological evaluation was made at 3.25 (SD = 2.74 years from surgery in CE group and at 6.47 (SD = 2.77 in CE+ group. Results The Medulloblastoma group showed severe executive deficit (≤ 1.5 SD below normal mean in all assessed tests, the most severe occurring in vermal patients. The Astrocytoma group also showed executive deficits in digits span, semantic fluency (animal category and moderate to slight deficit in Stroop (word and colour tests. In the astrocytoma group, the tumor's localization and dentate affectation showed different profile and level of impairment: moderate to slight for vermal and hemispheric patients respectively. The resected volume, age at surgery and the time between surgery-evaluation correlated with some neuropsychological executive variables

  12. Attention, effort, and fatigue: Neuropsychological perspectives (United States)

    Cohen, Ronald A.; Odonnell, Brian F.


    Models of attention, effort, and fatigue are reviewed. Methods are discussed for measuring these phenomena from a neuropsychological and psychophysiological perspective. The following methodologies are included: (1) the autonomic measurement of cognitive effort and quality of encoding; (2) serial assessment approaches to neurophysiological assessment; and (3) the assessment of subjective reports of fatigue using multidimensional ratings and their relationship to neurobehavioral measures.

  15. Use of the Rorschach test in neuropsychology

    Directory of Open Access Journals (Sweden)

    Ana Ožura


    Full Text Available The Rorschach test is widely used as a part of the assessment in clinical psychology in the world. It is also often used as a part of neuropsychological assessment in our unit at Division of Neurology in Ljubljana. We are presenting a review of clinically relevant information for the use of the Rorschach test in clinical practice with an emphasis on neuropsychology. The Rorschach test was considered a controversial instrument in the past. We are presenting a summary of research on its utility and psychometric characteristics. The number of studies in the field of neuropsychological application of the Rorschach test is limited. We describe theoretical models of cognitive processes involved in the process of solving the Rorschach test as a problem solving test apart from projection processes. The test however still lacks a theoretical basis formed on the brain behavior relations that is needed for every neuropsychological test. Nevertheless we noticed a recent growing interest in the published literature for finding neurological correlates of the response process in this test. Our research with patients with multiple sclerosis performed is described. We state implications for further research.

  16. Approaching neuropsychological tasks through adaptive neurorobots (United States)

    Gigliotta, Onofrio; Bartolomeo, Paolo; Miglino, Orazio


    Neuropsychological phenomena have been modelized mainly, by the mainstream approach, by attempting to reproduce their neural substrate whereas sensory-motor contingencies have attracted less attention. In this work, we introduce a simulator based on the evolutionary robotics platform Evorobot* in order to setting up in silico neuropsychological tasks. Moreover, in this study we trained artificial embodied neurorobotic agents equipped with a pan/tilt camera, provided with different neural and motor capabilities, to solve a well-known neuropsychological test: the cancellation task in which an individual is asked to cancel target stimuli surrounded by distractors. Results showed that embodied agents provided with additional motor capabilities (a zooming/attentional actuator) outperformed simple pan/tilt agents, even those equipped with more complex neural controllers and that the zooming ability is exploited to correctly categorising presented stimuli. We conclude that since the sole neural computational power cannot explain the (artificial) cognition which emerged throughout the adaptive process, such kind of modelling approach can be fruitful in neuropsychological modelling where the importance of having a body is often neglected.

  17. Cognitive Deficits in Breast Cancer Survivors After Chemotherapy and Hormonal Therapy. (United States)

    Frank, Jennifer Sandson; Vance, David E; Triebel, Kristen L; Meneses, Karen M


    Adjuvant treatments, specifically chemotherapy and hormonal therapy, have dramatically increased breast cancer survival, resulting in increased attention to the residual effects of treatment. Breast cancer survivors (BCS) frequently report that cognitive deficits are a particular source of distress, interfering with many aspects of quality of life. The literature on neuropsychological performance measures in BCS supports the reality of subtle cognitive deficits after both chemotherapy and hormonal therapy. This premise is supported by recent imaging studies, which reveal anatomical changes after chemotherapy as well as changes in patterns of neural activation while performing cognitive tasks. This review suggests that, even when performance on neuropsychological performance measures is within normal limits, BCS may be using increased cognitive resources in the face of reduced cognitive reserve. Potential interventions for cognitive deficits after adjuvant therapy include prescriptions for healthy living, pharmacotherapy, complementary therapy, and cognitive remediation therapy directed toward specific cognitive deficits or a combination of several strategies.

  18. Neuropsychological differences between attention deficit hyperactivity disorder and control children and adolescents referred for academic impairment Diferenças neuropsicológicas entre crianças e adolescentes portadores de transtorno da falta de atenção com hiperatividade e controles encaminhados por comprometimento acadêmico

    Directory of Open Access Journals (Sweden)

    Gabriel Coutinho


    Full Text Available OBJECTIVE: To compare the performances of children and adolescents with attention deficit hyperactivity disorder with a group of control comparison subjects, both taken from a large clinical sample, using some of the most widely employed attention-based Brazilian tests. METHOD: The performances of 186 children and adolescents with attention deficit hyperactivity disorder were compared to that of 80 control individuals based on attention and working memory scores. Both groups had been referred due to academic impairment. All individuals were submitted to the TAVIS-3 sustained, shifted and focused attention tests, as well as to the working memory tests that make up the WISC-III Freedom from Distractibility Index (Digit Span and Arithmetic. RESULTS: The control group was slightly older than the attention deficit hyperactivity disorder group (p = 0.07; IQ and schooling did not differ between groups (p = 0.34 and p = 0.38, respectively. While performing a test requiring sustained attention for a longer period of time, the attention deficit hyperactivity disorder group showed a significantly higher number of commission errors compared to the controls, thus presenting sustained attention deficits (p = 0.003; when the influence of IQ, age and schooling was reduced, the attention deficit hyperactivity disorder group also made more omission errors during a sustained attention task in comparison to the control group, thus achieving a borderline significance level (p = 0.08; the attention deficit hyperactivity disorder group also performed worse in Digit Span forward and backward (p = 0.013 and p = 0.01, respectively and in Arithmetic (p = 0.008. Other scores did not achieve significance. CONCLUSION : Our findings suggest that some of the most commonly used Brazilian attention-based tests - especially the sustained attention and working memory tests - may be useful to help distinguish subjects with attention deficit hyperactivity disorder from control

  19. Evaluation of a sports program in modifying the symptoms of hyperactivity, inattention and impulsiveness applied to children with Attention Deficit Disorder

    Directory of Open Access Journals (Sweden)

    Paula María Jiménez Palomar


    Full Text Available The sport is a phenomenon that contributes to physical health, mental balance and social welfare of the user, and promotes a range of habits and values that impact on the further integration of the individual in their environment. People suffering from Attention Deficit Disorder with Hyperactivity, these abilities are impaired and currently studies are needed to support the hypothesis that physical exercise can be an effective adjunct to this problem. This will do a clinical trial to evaluate the effectiveness of a sports program, which seeks to alter the predominant symptoms of Attention Deficit Disorder with Hypeeractivity. The study will be conducted in the Unit of Child and Adolescent Mental Health in Ciudad Real, and participants will be children between 6 and 12 years with this disorder. It shall consist of the comparison of two groups: one that will only receive the normal care given in the unit and another that will be applied also a sports program. The second will be divided into two groups who will implement the program outdoors or indoors, in order to observe any difference between an environment and another. We will assess impulsivity, inattention and hyperactivity using the Conners scale for teachers, school performance, taking into account the quarterly grades and behavior at home with the Conners scale for parents.

  20. Neuropsychological assessment and the Disability Rating Scale (DRS): a concurrent validity study. (United States)

    Neese, L E; Caroselli, J S; Klaas, P; High, W M; Becker, L J; Scheibel, R S


    Assessment of current level of functioning among clients with traumatic brain injury (TBI) often guides the establishment of realistic outcome goals for post-acute rehabilitation. Further, data generated from neuropsychological testing provide a clinician with a better understanding of a client's pattern of cognitive strengths and weaknesses. The Disability Rating Scale (DRS) is commonly used by TBI rehabilitation facilities to assess a client's general level of functioning in terms of impairment, disability, and handicap. Previous studies have used clients' neuropsychological test results to predict future level of functioning. These studies have shown mixed results regarding the predictive validity of the test findings; however, they usually employ only a limited number of tests for prediction representing a limited number of cognitive domains. Using a concurrent validity design, the present study investigated the bivariate associations between various neuropsychological testing domains (i.e. intellectual, academic, language, visuoperceptual, memory, and executive functioning) and level of functioning as indexed by the DRS. Participants were administered the DRS and the neuropsychological evaluation during the initial part of post-acute rehabilitation. Composite scores were derived for each of the neuropsychological domains. Most participants were categorized as sustaining a severe TBI. The mean age and education of this predominately male sample was 28.84 years (SD = 9.13) and 11.83 years (SD = 1.7), respectively. Results revealed a significant positive relationship between performances in intellectual, executive, academic, and visuoperceptual domains and level of functioning.

  1. Parametric model measurement: reframing traditional measurement ideas in neuropsychological practice and research. (United States)

    Brown, Gregory G; Thomas, Michael L; Patt, Virginie

    Neuropsychology is an applied measurement field with its psychometric work primarily built upon classical test theory (CTT). We describe a series of psychometric models to supplement the use of CTT in neuropsychological research and test development. We introduce increasingly complex psychometric models as measurement algebras, which include model parameters that represent abilities and item properties. Within this framework of parametric model measurement (PMM), neuropsychological assessment involves the estimation of model parameters with ability parameter values assuming the role of test 'scores'. Moreover, the traditional notion of measurement error is replaced by the notion of parameter estimation error, and the definition of reliability becomes linked to notions of item and test information. The more complex PMM approaches incorporate into the assessment of neuropsychological performance formal parametric models of behavior validated in the experimental psychology literature, along with item parameters. These PMM approaches endorse the use of experimental manipulations of model parameters to assess a test's construct representation. Strengths and weaknesses of these models are evaluated by their implications for measurement error conditional upon ability level, sensitivity to sample characteristics, computational challenges to parameter estimation, and construct validity. A family of parametric psychometric models can be used to assess latent processes of interest to neuropsychologists. By modeling latent abilities at the item level, psychometric studies in neuropsychology can investigate construct validity and measurement precision within a single framework and contribute to a unification of statistical methods within the framework of generalized latent variable modeling.

  2. Aphasia diagrams: a new notational scheme for representing neurolinguistic deficits. (United States)

    Westbury, C; Bub, D


    Models of language processing are becoming extremely complex. As a result, it has become very difficult to develop a thorough understanding of even a single patient's deficits, let alone to represent those deficits in a way which renders their significance apparent to others. In this paper, we describe and demonstrate the use of a notational system which has been developed specifically for representing the complexities of neurolinguistic deficits. The notational system is simple to learn and to use and may easily be extended and adapted to different models of language processing. It may also be used to represent the results from other nonlinguistic neuropsychological batteries which are composed of tightly interdependent subtests with many related factors included in each subtest. Despite its simplicity, the notational system has proven itself in the field as a useful tool for rendering complex deficits more easily interpretable.

  3. Attention Contributes to Arithmetic Deficits in New-Onset Childhood Absence Epilepsy

    Directory of Open Access Journals (Sweden)

    Dazhi Cheng


    Full Text Available Neuropsychological studies indicate that new-onset childhood absence epilepsy (CAE is associated with deficits in attention and executive functioning. However, the contribution of these deficits to impaired academic performance remains unclear. We aimed to examine whether attention and executive functioning deficits account for the academic difficulties prevalent in patients with new-onset CAE. We analyzed cognitive performance in several domains, including language, mathematics, psychomotor speed, spatial ability, memory, general intelligence, attention, and executive functioning, in 35 children with new-onset CAE and 33 control participants. Patients with new-onset CAE exhibited deficits in mathematics, general intelligence, attention, and executive functioning. Furthermore, attention deficits, as measured by a visual tracing task, accounted for impaired arithmetic performance in the new-onset CAE group. Therefore, attention deficits, rather than impaired general intelligence or executive functioning, may be responsible for arithmetic performance deficits in patients with new-onset CAE.

    Full Text Available Background. The Barkley Adult Attention Deficit/Hyperactivity Disorder (ADHD Rating Scale-IV (BAARS-IV was developed, and it demonstrated good psychometric properties. The BAARS-IV includes 27 questions on the symptoms of adult ADHD. The purpose of the present study is to investigate the psychometric testing of the Persian version of BAARS-IV among the elderlies in Tabriz City. Method. This cross-sectional study was conducted in Tabriz City—in the west of Iran—in 2015 via enrolling of 121 old-aged people. We did the process of translation and adaptation of BAARS-IV and examined its concurrent validity, internal consistency, and test-retest reliability. Result. The BAARS-IV demonstrated good internal consistency and test-retest reliability. Correlations between the BAARS-IV and the CAARS-S: SV were high and evidence supporting concurrent validity was revealed. Cronbach’s alpha for the overall scale and subscales stood at 0.89, 0.81, 0.66, 0.56, and 0.82, respectively. Conclusion. The Persian BAARS-IV showed acceptable reliability and validity. BAARS-IV was determined to be composed of internally consistent and psychometrically sound items.

    Vegue-González, Milagros; Álvaro-Brun, Enrique; Santiago-Sáez, Andrés; Kanaan-Kanaan, Atef


    The aim of this study is to determine the prevalence of childhood history of attention deficit hyperactivity disorder (ADHD) in a sample of prison inmates. This is a descriptive, cross-sectional study, which consisted of a sample of 100 inmates from penitentiary centers in Madrid. The instruments used were the Wender Utah Rating Scale (WURS), the International Personality Disorder Examination, and a questionnaire of demographic, penitentiary, and toxicological data. For statistical analysis, the SPSS program was used with confidence interval estimation of 95%. The mean score of the WURS was 65.7 points. Fifty percent of the sample surpassed the cut-off point of 32 for the 25 best discriminative items in the Spanish validated version. A significant association was found between a childhood history of ADHD and antisocial and borderline personality disorders. The disorder was also found to be associated with autoaggressive behavior, more probability to be sanctioned in prison, and have a history of substance dependence. © 2011 American Academy of Forensic Sciences.

  6. Adaptive skills are useful for evaluating the effect of pharmacological treatment in children with attention-deficit/hyperactivity disorder. (United States)

    Lindblad, Ida; Nasic, Salmir; Landgren, Magnus; Svensson, Leif; Gillberg, Christopher; Fernell, Elisabeth


    There are few long-term studies of adaptive functions as an outcome measure of pharmacological treatment in attention-deficit/hyperactivity disorder (ADHD). This study assessed the adaptive abilities of children with ADHD before and after several years of pharmacological treatment. We studied 12 children with a mean age of 15 years - seven boys and five girls - who had continued pharmacological treatment for ADHD for more than four years. The Adaptive Behaviour Assessment Scales - Second Edition ratings by their teachers were compared before and after they had received treatment for ADHD. On a group level, the conceptual, practical and general adaptive composite domains improved significantly between the baseline and follow-up study. There were clear individual variations: more than half of the group increased from an adaptive level far below average to average, a minority displayed no major changes, and one individual deteriorated. The girls tended to have better outcomes than the boys. This study was nonrandomised and only analysed within-group changes in a small number of participants. However, the findings suggest that four to five years of stimulant treatment had markedly positive effects on adaptive functioning in more than half of the school-age children with ADHD. ©2016 Foundation Acta Paediatrica.

  7. Evaluation of motor proficiency and adiponectin in adolescent students with attention deficit hyperactivity disorder after high-intensity intermittent training. (United States)

    Torabi, Farnaz; Farahani, Abolfazl; Safakish, Sepide; Ramezankhani, Azam; Dehghan, Firouzeh


    Attention deficit hyperactivity disorder (ADHD) is a chronic condition with frequent comorbidities such as obesity, troubled relationships, low self-esteem, and difficulty in motor proficiency. This study aims to elucidate the effect of high-intensity intermittent training on motor proficiency, adiponectin, and insulin resistance in adolescent students with ADHD disorder. Fifty adolescent students of both genders with ADHD diagnosis participated and assigned into four experimental groups (each group with 15 girls and 10 boys students; two experimental and two control groups). High-intensity intermittent training was performed continuously 3 times a week for 6 weeks in experimental groups. Serum adiponectin level significantly increased in the experimental groups of both genders after 6 weeks intermittent training while insulin resistance levels were markedly decreased. Furthermore, motor proficiency score were significantly improved in the experimental groups of both genders. In addition gender had no significant impact on adiponectin, insulin resistance and motor proficiency rating. The findings of this study suggest that high intensity intermittent training improved physiological systems in ADHD population that leads to reduce risk factors for future development of comorbidities.

  8. Neuropsychological Assessment of Executive Function in Adolescents with Different Alcohol Consumption Patterns

    Directory of Open Access Journals (Sweden)

    Laura M. V. Manoiloff


    Full Text Available The principal goal of this study was to evaluate the neuropsychological performance in Executive Function (EF tasks in adolescents with different patterns of alcohol use. An ex – post facto simple prospective design was used and three groups were identified in regard to alcohol drinking patterns (DP: light drinkers, moderate drinkers, and Binge drinkers. No differences were found in neuropsychological performance in EF tasks related to DP. Results of the present work highlights relevant issues that need to be considered in future works, like the importance of a better assessment of DP among Argentinean adolescents and the implementation of neuropsychological tasks developed to assess emotional aspects of EF, such us the decision making tasks.

  9. School children with neuropsychological handicap: coping strategies and parents' impact. (United States)

    Krener, P; Cranston, C


    One hundred forty six boys (mean age 9 years 1 months, SD = two years, nine months) and forty one girls (mean age 8 years 6 months, SD = three years, three months) received medical, developmental, psychoeducational, and psychiatric evaluations in a multidisciplinary developmental pediatric clinic. Two hundred fifty variables were analyzed by developing ten scales to quantitatively evaluate neuropsychological risk factors, family and parent functioning, and outcome measures of academic achievement, social adjustment and coping or psychiatric symptom pattern. Higher academic achievement, and lower behavioral symptomatology were associated with high IQ scores but not with higher scores on neurobehavioral risk factors. Chief complaints reported by parents did not correlate with their children's final psychiatric diagnoses and also were found to be independent of children's coping styles observed in the office. Problem parenting, as observed in the pediatrician's office, was associated with behavioral problems, and also with decreased competence on language measures and lower academic achievement in relation to IQ. In this sample, assessing parenting yielded a stronger prediction of the child's school and behavioral functioning than did taking a detailed history of neuropsychological risk factors.

  10. Neuropsychological differential diagnosis of mild traumatic brain injury. (United States)

    Larrabee, Glenn J; Rohling, Martin L


    The diagnosis and evaluation of mild traumatic brain injury (mTBI) is reviewed from the perspective of meta-analyses of neuropsychological outcome, showing full recovery from a single, uncomplicated mTBI by 90 days post-trauma. Persons with history of complicated mTBI characterized by day-of-injury computed tomography or magnetic resonance imaging abnormalities, and those who have suffered prior mTBIs may or may not show evidence of complete recovery similar to that experienced by persons suffering a single, uncomplicated mTBI. Persistent post-concussion syndrome (PCS) is considered as a somatoform presentation, influenced by the non-specificity of PCS symptoms which commonly occur in non-TBI samples and co-vary as a function of general life stress, and psychological factors including symptom expectation, depression and anxiety. A model is presented for forensic evaluation of the individual mTBI case, which involves open-ended interview, followed by structured interview, record review, and detailed neuropsychological testing. Differential diagnosis includes consideration of other neurologic and psychiatric disorders, symptom expectation, diagnosis threat, developmental disorders, and malingering.

  11. Association between the attention deficits and delinquency

    Directory of Open Access Journals (Sweden)

    Robert Opora


    Full Text Available In the society we can find a lot of prejudices concerning AD/HD. The article contains facts and evidence based on research presenting that the delinquency is very often a distant complication of attention deficits but it doesn’t mean that a child with attention deficits has to be delinquent. The article describes the association between the attention deficits and delinquency. There are presented some risk factors coming from the attention deficits and protective factors which let the child follow the social norms. The research was based on 108 delinquent juveniles staying under the probation supervision. The purpose of the research was to evaluate the frequency of the attention deficits among delinquent juveniles staying under supervision. The research findings concern also the association between the attention deficit and external behavioural disorders. In the summary several conditions are described which are important to protect children with attention deficit from delinquency.

  15. Neuropsychological outcomes in CHD beyond childhood: a meta-analysis. (United States)

    Mills, Rónán; McCusker, Christopher G; Tennyson, Chris; Hanna, Donncha


    Risk for neurodevelopmental delay in infants and children with CHD is well established, but longer-term outcomes are equivocal. A meta-analysis was conducted to establish whether cognitive deficits remain beyond childhood - into teenage and young adult years. Methods and results A total of 18 unique samples, involving adolescents, teenagers, and adults with CHD significant enough to require invasive intervention, and sourced through searches of Web of Science, MEDLINE, CINAHL Plus, and PsychInfo, met the inclusion criteria. These included the use of standardised neuropsychology tests across 10 domains of cognitive functioning and the reporting of effect size differences with controls. Reports of patients with chromosomal or genetic abnormalities were excluded. Pooled effect sizes suggested no significant differences between CHD samples and controls in terms of general intellectual ability and verbal reasoning. However, small-medium effects sizes were noted (0.33-0.44) and were statistically significant within the domains of non-verbal reasoning, processing speed, attention, auditory-verbal memory, psychomotor abilities, numeracy, and literacy with executive functioning also emerging as significant when one study outlier was excluded. We also included quality assurance statistics including Cochran's Q, T, and I2 statistics, leave-one-out analyses, and assessment of publication bias. These often suggested study variability, possibly related to the heterogeneity of diagnostic groups included, and different tests used to measure the same construct. Heterogeneity indicated that moderators affect cognitive outcomes in CHD. Nevertheless, deficits across cognitive domains were discerned, which are likely to have functional impact and which should inform practice with this clinical population.

  16. Arithmetical calculation and related neuropsychological skills in subjects with isolated oral clefts. (United States)

    Goodwin, Jon W; Conrad, Amy L; Ansley, Timothy; Nopoulos, Peg


    The current study examined whether the arithmetical calculation skills of children, adolescents, and young adults with isolated cleft of the lip and/or palate (iCL/P) differ significantly from unaffected control participants. Comparisons of potential neuropsychological predictors of arithmetical calculation were also conducted to determine whether these variables differ significantly for participants with iCL/P. Participants (N = 176; 93 iCL/P and 83 Control) ranged in age from 7 to 26 years old. A standardized battery of achievement and neuropsychological skills was administered. Between group differences on math achievement was assessed through a univariate analysis of covariance. Relationships between neuropsychological measures and math achievement were analyzed separately for participants with iCL/P and controls through hierarchical linear regressions. Arithmetical calculation was significantly lower for the iCL/P group. Rapid naming, sustained attention, and visual-spatial organization were significant predictors for the iCL/P group; rapid naming was the lone variable that was significantly more predictive of arithmetical calculation for the iCL/P group than for control participants. These results suggest that inefficient verbal label retrieval related to short-term memory (STM) deficits underlie the calculation difficulties of individuals with iCL/P. These findings have implications for approaches to remediation, as well as future research. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

  17. Childhood- versus adolescent-onset antisocial youth with conduct disorder: psychiatric illness, neuropsychological and psychosocial function.

    Directory of Open Access Journals (Sweden)

    Vicki A Johnson

    Full Text Available The present study investigates whether youths with childhood-onset antisocial behavior have higher rates of psychiatric illness, neuropsychological and psychosocial dysfunction than youths who engage in antisocial behavior for the first time in adolescence. Prior studies have generally focused on single domains of function in heterogeneous samples. The present study also examined the extent to which adolescent-onset antisocial behavior can be considered normative, an assumption of Moffitt's dual taxonomy model.Forty-three subjects (34 males, 9 females, mean age = 15.31, age range 12-21 with a diagnosis of conduct disorder (CD were recruited through Headspace Services and the Juvenile Justice Community Centre. We compared childhood-onset antisocial youths (n = 23 with adolescent-onset antisocial youths (n = 20 with a conduct disorder, across a battery of psychiatric, neuropsychological and psychosocial measures. Neuropsychological function of both groups was also compared with normative scores from control samples.The childhood-onset group displayed deficits in verbal learning and memory, higher rates of psychosis, childhood maltreatment and more serious violent behavior, all effects associated with a large effect size. Both groups had impaired executive function, falling within the extremely low range (severely impaired.Childhood-onset CD displayed greater cognitive impairment, more psychiatric symptoms and committed more serious violent offences. The finding of severe executive impairment in both childhood- and adolescent-onset groupings challenges the assumption that adolescent-onset antisocial behavior is a normative process.

    Woods, Damith; Sirirat, Schwanagorn; Pattara-Angkoon, Sirirada; Rattanajan, Janja


    We report the clinical assessment of J.P., an 86 year-old man with Broca's aphasia complaining of memory problems. Our aim was to objectively investigate his level of cognitive functioning using standardized neuropsychological tests in order to determine the nature of his memory impairment. J.P.'s medical history included left-middle cerebral artery (left-MCA) stroke, high frequency hearing loss, macular degeneration, and a recent hospitalization related to a fall. Results from his neuropsychological testing and from information gathered during the clinical interview with his wife suggested that a deficit in executive functioning might have been the source for some of his perceived memory problems. We were unable to detect any progressive cognitive decline that might have been suggestive of something more sinister. Despite his age J.P. was a fully functioning and highly contributing member of his society who was completing quite complex activities of daily living (ADLs). We provided J.P. with a compensatory set of strategies in order for him to circumvent his executive difficulties and impairment in expressive language. In the elderly population survivors of stroke are continuing to rise with improvements in drug treatment and primary care. This case study is important as it provides information on neuropsychological assessment in aphasia; and draws attention to valuable information in a client's clinical history that might help clarify the prognosis.

    Full Text Available Patients with aluminum hydroxide adjuvant-induced macrophagic myofasciitis (MMF complain of arthromyalgias, chronic fatigue and cognitive deficits. This study aimed to characterize brain perfusion in these patients.Brain perfusion SPECT was performed in 76 consecutive patients (aged 49±10 y followed in the Garches-Necker-Mondor-Hendaye reference center for rare neuromuscular diseases. Images were acquired 30 min after intravenous injection of 925 MBq 99mTc-ethylcysteinate dimer (ECD at rest. All patients also underwent a comprehensive battery of neuropsychological tests, within 1.3±5.5 mo from SPECT. Statistical parametric maps (SPM12 were obtained for each test using linear regressions between each performance score and brain perfusion, with adjustment for age, sex, socio-cultural level and time delay between brain SPECT and neuropsychological testing.SPM analysis revealed positive correlation between neuropsychological scores (mostly exploring executive functions and brain perfusion in the posterior associative cortex, including cuneus/precuneus/occipital lingual areas, the periventricular white matter/corpus callosum, and the cerebellum, while negative correlation was found with amygdalo-hippocampal/entorhinal complexes. A positive correlation was also observed between brain perfusion and the posterior associative cortex when the time elapsed since last vaccine injection was investigated.Brain perfusion SPECT showed a pattern of cortical and subcortical changes in accordance with the MMF-associated cognitive disorder previously described. These results provide a neurobiological substrate for brain dysfunction in aluminum hydroxide adjuvant-induced MMF patients.

  20. Distinct neuropsychological subgroups in typically developing youth inform heterogeneity in children with ADHD. (United States)

    Fair, Damien A; Bathula, Deepti; Nikolas, Molly A; Nigg, Joel T


    Research and clinical investigations in psychiatry largely rely on the de facto assumption that the diagnostic categories identified in the Diagnostic and Statistical Manual (DSM) represent homogeneous syndromes. However, the mechanistic heterogeneity that potentially underlies the existing classification scheme might limit discovery of etiology for most developmental psychiatric disorders. Another, perhaps less palpable, reality may also be interfering with progress-heterogeneity in typically developing populations. In this report we attempt to clarify neuropsychological heterogeneity in a large dataset of typically developing youth and youth with attention deficit/hyperactivity disorder (ADHD), using graph theory and community detection. We sought to determine whether data-driven neuropsychological subtypes could be discerned in children with and without the disorder. Because individual classification is the sine qua non for eventual clinical translation, we also apply support vector machine-based multivariate pattern analysis to identify how well ADHD status in individual children can be identified as defined by the community detection delineated subtypes. The analysis yielded several unique, but similar subtypes across both populations. Just as importantly, comparing typically developing children with ADHD children within each of these distinct subgroups increased diagnostic accuracy. Two important principles were identified that have the potential to advance our understanding of typical development and developmental neuropsychiatric disorders. The first tenet suggests that typically developing children can be classified into distinct neuropsychological subgroups with high precision. The second tenet proposes that some of the heterogeneity in individuals with ADHD might be "nested" in this normal variation.

  1. Increased risk of neuropsychological disorders in children born preterm without major disabilities: a neurodevelopmental model

    Directory of Open Access Journals (Sweden)

    Dipasquale Filippo


    Full Text Available Over the past 30 years, preterm births have drastically increased and today represent 12.5% of total births. About 1.2% of preterm births characterize very preterm births (GA<32weeks that, with very low birth weight (BW<1500grams, are constantly found as risk factors of unfavourable neurological outcomes in longitudinal follow up studies. Actually, also “late preterm” children (preterm born from 33 to 36 weeks of gestational age, normally considered at low risk for neurodevelopmental disabilities, are supposed to represent a population of children to be monitored. Previous findings of a general cognitive impairment in children born preterm have gradually addressed the assessment of more specific neuropsychological skills and pointed out the importance to follow these children up to adolescent age. The neuroanatomical prerequisite of an abnormality in frontal lobe development and the correlation with various neuropsychological dysfunctions (fine and gross motor disabilities, executive function and working memory deficits, visual-constructional and attentional dysfunctions underline the interference of preterm birth with normal brain maturational phases. Though showing more demanding neurodevelopmental pathways than term peers, a large number of preterm children tend to functionally normalize in adolescence. The review supports the hypothesis of a neurodevelopmental model that can be at risk to influence dysfunctional neuropsychological outcome.

  2. Neuropsychological Functioning, Coping, and Quality of Life among Returning War Veterans (United States)

    Martindale, Sarah L.; Morissette, Sandra B.; Kimbrel, Nathan A.; Meyer, Eric C.; Kruse, Marc I.; Gulliver, Suzy B.; Dolan, Sara L.


    Purpose The present research tested the hypothesis that action- and emotion-focused coping strategies would mediate the relationship between neuropsychological functioning and quality of life among a sample of returning Iraq/Afghanistan veterans. Method Veterans (N = 130) who served as part of the wars in Iraq and Afghanistan, completed a diagnostic assessment of PTSD, a battery of questionnaires assessing coping style, traumatic brain injury (TBI), and quality of life, and neuropsychological tests measuring attention, learning and memory, working memory, inhibition, executive control, and visual motor coordination. Results Executive control, immediate and delayed verbal recall, and visual motor coordination were associated with quality of life. However, after controlling for the effects of combat exposure, PTSD, and probable TBI, no measure of neuropsychological functioning was directly associated with quality of life. Mediation analyses indicated that delayed verbal recall influenced quality of life through its effect on action-focused coping. Conclusions Although replication is needed, these findings indicate that delayed verbal recall may indirectly influence quality of life among Iraq/Afghanistan veterans through its association with action-focused coping strategies. Psychologists who are working with veterans that are experiencing memory difficulties and poor quality of life may consider focusing on improving coping skills prior to rehabilitation of memory deficits.

  3. The neuropsychology of obsessive-compulsive personality disorder: a new analysis. (United States)

    Fineberg, Naomi A; Day, Grace A; de Koenigswarter, Nica; Reghunandanan, Samar; Kolli, Sangeetha; Jefferies-Sewell, Kiri; Hranov, Georgi; Laws, Keith R


    Obsessive compulsive personality disorder (OCPD) is characterized by perfectionism, need for control, and cognitive rigidity. Currently, little neuropsychological data exist on this condition, though emerging evidence does suggest that disorders marked by compulsivity, including obsessive-compulsive disorder (OCD), are associated with impairment in cognitive flexibility and executive planning on neurocognitive tasks. The current study investigated the neurocognitive profile in a nonclinical community-based sample of people fulfilling diagnostic criteria for OCPD in the absence of major psychiatric comorbidity. Twenty-one nonclinical subjects who fulfilled Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria for OCPD were compared with 15 healthy controls on selected clinical and neurocognitive tasks. OCPD was measured using the Compulsive Personality Assessment Scale (CPAS). Participants completed tests from the Cambridge Automated Neuropsychological Test Battery including tests of set shifting (Intra-Extra Dimensional [IED] Set Shifting) executive planning (Stockings of Cambridge [SOC]), and decision making (Cambridge Gamble Task [CGT]). The OCPD group made significantly more IED-ED shift errors and total shift errors, and also showed longer mean initial thinking time on the SOC at moderate levels of difficulty. No differences emerged on the CGT. Nonclinical cases of OCPD showed significant cognitive inflexibility coupled with executive planning deficits, whereas decision-making remained intact. This profile of impairment overlaps with that of OCD and implies that common neuropsychological changes affect individuals with these disorders.

  4. Obsessive compulsive disorder networks: positron emission tomography and neuropsychology provide new insights.

    Bruno Millet

    Full Text Available BACKGROUND: Deep brain stimulation has shed new light on the central role of the prefrontal cortex (PFC in obsessive compulsive disorder (OCD. We explored this structure from a functional perspective, synchronizing neuroimaging and cognitive measures. METHODS AND FINDINGS: This case-control cross-sectional study compared 15 OCD patients without comorbidities and not currently on serotonin reuptake inhibitors or cognitive behavioural therapy with 15 healthy controls (matched for age, sex and education level on resting-state (18FDG-PET scans and a neuropsychological battery assessing executive functions. We looked for correlations between metabolic modifications and impaired neuropsychological scores. Modifications in glucose metabolism were found in frontal regions (orbitofrontal cortex and dorsolateral cortices, the cingulate gyrus, insula and parietal gyrus. Neuropsychological differences between patients and controls, which were subtle, were correlated with the metabolism of the prefrontal, parietal, and temporal cortices. CONCLUSION: As expected, we confirmed previous reports of a PFC dysfunction in OCD patients, and established a correlation with cognitive deficits. Other regions outside the prefrontal cortex, including the dorsoparietal cortex and the insula, also appeared to be implicated in the pathophysiology of OCD, providing fresh insights on the complexity of OCD syndromes.

    déficits antecederiam o desenvolvimento dos transtornos alimentares, podendo, assim, contribuir para seu desenvolvimento ou para um pior prognóstico. O melhor delineamento do perfil cognitivo dos pacientes com transtorno alimentar torna-se importante para orientar abordagens terapêuticas mais seletivas.BACKGROUND: The pathophysiology of eating disorders is still unknown, with many factors possibly involved. The existence of a central nervous system (CNS dysfunction is being investigated with particular interest. One of the most employed strategies to reach this goal is the evaluation of cognitive functioning of patients with eating disorders with neuropsychological tests. OBJECTIVE: To evaluate the current knowledge about the neuropsychology of ED. METHODS: We performed a review of several data bases (including MedLINE, PsychoINFO, LILACS and Cochrane Data Bank, using terms related to main theme of interest. The review comprised articles published up to January, 2004. RESULTS: Anorexia Nervosa (AN was t­ ­ he most studied ED from the neuropsychological point-of-view, with studies tending to elicit attentive, visuo-spatial, and visuo-constructive deficits among such patients. On the other side, patients with Bulimia Nervosa (BN exhibited déficits in the selective aspects of attention and in executive functions. As yet, there is no study covering the neuropsychological aspects of binge-eating disorder. After successful treatment, individuals show improvement of some cognitive deficits, while other seem to persist. CONCLUSIONS: The ED are possibly associated with a certain degree of neuropsychological dysfunction, even though there is no consesus with regard to which function is particularly impaired. The fact that some cognitive dysfunction tend to disappear after treatment argues in favor of the hypothesis that these are functional deficits. Other deficits, however, tend to persist, suggesting that they may precede the development of eating disorders or even

  6. Neuropsychology of deep brain stimulation in neurology and psychiatry. (United States)

    Troster, Alexander I


    Deep brain stimulation (DBS) experienced resurgence in the 1990s when limitations in pharmacotherapy and ablative surgery for movement disorders (including neuropsychological deficits) were appreciated. Subthalamic DBS for Parkinson's disease has received the most empirical attention and may entail cognitive and psychiatric adverse events in approximately 10% of patients. This article reviews the cognitive alterations after thalamic, pallidal, and subthalamic DBS for movement disorders (including, Parkinson's disease, essential tremor, and dystonia) and the possible etiology and mechanisms underlying neurobehavioral changes. Initial studies of neurobehavioral outcomes of DBS for emerging indications such as epilepsy, obsessive compulsive disorder, depression, Tourette's syndrome, and persistent vegetative or minimally conscious state are also reviewed. DBS for currently accepted indications appears safe from a cognitive standpoint in that the procedure is associated with typically transient, mild, and circumscribed cognitive alterations (most commonly in verbal fluency), and improved mood state and quality of life. A minority of patients experience more widespread, persistent, or serious cognitive and psychiatric sequelae, although research to date has failed to identify reliable risk factors for such adverse events.

  7. Profiles of Impaired, Spared, and Recovered Neuropsychological Processes in Alcoholism (United States)

    Oscar-Berman, Marlene; Valmas, Mary M.; Sawyer, Kayle S.; Ruiz, Susan Mosher; Luhar, Riya B.; Gravitz, Zoe R.


    Long-term chronic alcoholism is associated with disparate and widespread residual consequences for brain functioning and behavior, and alcoholics suffer a variety of cognitive deficiencies and emotional abnormalities. Alcoholism has heterogeneous origins and outcomes, depending upon factors such as family history, age, gender, and mental or physical health. Consequently, the neuropsychological profiles associated with alcoholism are not uniform among individuals. Moreover, within and across research studies, variability among participants is substantial and contributes to characteristics associated with differential treatment outcomes after detoxification. In order to refine our understanding of alcoholism-related impaired, spared, and recovered abilities, we focus on five specific functional domains: (1) memory, (2) executive functions, (3) emotion and psychosocial skills, (4) visuospatial cognition, and (5) psychomotor abilities. The brain systems that are most vulnerable to alcoholism are the frontocerebellar and mesocorticolimbic circuitries. Over time, with abstinence from alcohol, the brain appears to become reorganized to provide compensation for structural and behavioral deficits. By relying on a combination of clinical and scientific approaches, future research will help to refine the compensatory roles of healthy brain systems, the degree to which abstinence and treatment facilitate the reversal of brain atrophy and dysfunction, and the importance of individual differences to outcome.

  9. Connectionist neuropsychology: uncovering ultimate causes of acquired dyslexia. (United States)

    Woollams, Anna M


    Acquired dyslexia offers a unique window on to the nature of the cognitive and neural architecture supporting skilled reading. This paper provides an integrative overview of recent empirical and computational work on acquired dyslexia within the context of the primary systems framework as implemented in connectionist neuropsychological models. This view proposes that damage to general visual, phonological or semantic processing abilities are the root causes of different forms of acquired dyslexia. Recent case-series behavioural evidence concerning pure alexia, phonological dyslexia and surface dyslexia that supports this perspective is presented. Lesion simulations of these findings within connectionist models of reading demonstrate the viability of this approach. The commitment of such models to learnt representations allows them to capture key aspects of performance in each type of acquired dyslexia, particularly the associated non-reading deficits, the role of relearning and the influence of individual differences in the premorbid state of the reading system. Identification of these factors not only advances our understanding of acquired dyslexia and the mechanisms of normal reading but they are also relevant to the complex interactions underpinning developmental reading disorders.

  10. [Neuropsychology of Tourette's disorder: cognition, neuroimaging and creativity]. (United States)

    Espert, R; Gadea, M; Alino, M; Oltra-Cucarella, J


    Tourette's disorder is the result of fronto-striatal brain dysfunction affecting people of all ages, with a debut in early childhood and continuing into adolescence and adulthood. This article reviews the main cognitive, functional neuroimaging and creativity-related studies in a disorder characterized by an excess of dopamine in the brain. Given the special cerebral configuration of these patients, neuropsychological alterations, especially in executive functions, should be expected. However, the findings are inconclusive and are conditioned by factors such as comorbidity with attention deficit hyperactivity disorder and obsessive-compulsive disorder, age or methodological variables. On the other hand, the neuroimaging studies carried out over the last decade have been able to explain the clinical symptoms of Tourette's disorder patients, with special relevance for the supplementary motor area and the anterior cingulate gyrus. Finally, although there is no linear relationship between excess of dopamine and creativity, the scientific literature emphasizes an association between Tourette's disorder and musical creativity, which could be translated into intervention programs based on music.

  11. Neuropsychological function, anxiety, depression and pain impact in fibromyalgia patients. (United States)

    Cuevas-Toro, Ana M; López-Torrecillas, Francisca; Díaz-Batanero, M Carmen; Pérez-Marfil, M Nieves


    Cognitive deficits have a significant impact on the daily performance of fibromyalgia patients. This paper analyzes executive functioning and decision-making performance, and the relationships between these functions and pain, anxiety, depression and medication in fibromyalgia patients. A group of fibromyalgia patients (FG) (n = 85) was compared with a healthy control group (CG) (n = 85) in their performance in the Wisconsin Card Sorting Test (WCST) and the Iowa Gambling Task (IGT). In the WCST, results showed a percentage of non-perseverative errors significantly higher in the CG than in the FG (p = .026), the other variables (percentage of perseverative errors, number of categories and failures to maintain set) showed no significant differences. In relation to decision-making (IGT), once the rules had been learnt, the FG made fewer advantageous choices than the CG, but these differences were not statistically significant (p = .325). In the FG, pain severity (p = .010) and impact on daily activities (p = .016) interfered with decision-making, unlike anxiety, depression or medication, which did no relate to it. In executive function, pain and impact on daily activities were associated with the percentage of perseverative errors (p = .051) and the number of categories (p = .031), whereas pain severity was related to failures to maintain set (p = .039), indicative of increased distractibility and poor attentional ability. In conclusion, FG showed normal performance in executive functioning and decision-making. Moreover, pain was associated with neuropsychological functioning whereas anxiety, depression and medication were not.

  12. Symptom validity testing, effort, and neuropsychological assessment. (United States)

    Bigler, Erin D


    Symptom validity testing (SVT) has become a major theme of contemporary neuropsychological research. However, many issues about the meaning and interpretation of SVT findings will require the best in research design and methods to more precisely characterize what SVT tasks measure and how SVT test findings are to be used in neuropsychological assessment. Major clinical and research issues are overviewed including the use of the “effort” term to connote validity of SVT performance, the use of cut-scores, the absence of lesion-localization studies in SVT research, neuropsychiatric status and SVT performance and the rigor of SVT research designs. Case studies that demonstrate critical issues involving SVT interpretation are presented.

    Pedraza, Otto; Mungas, Dan


    The measurement of cognitive abilities across diverse cultural, racial, and ethnic groups has a contentious history, with broad political, legal, economic, and ethical repercussions. Advances in psychometric methods and converging scientific ideas about genetic variation afford new tools and theoretical contexts to move beyond the reflective analysis of between-group test score discrepancies. Neuropsychology is poised to benefit from these advances to cultivate a richer understanding of the f...

  14. Neuropsychological assessment of patients with severe neuromotor and verbal disabilities. (United States)

    Sabbadini, M; Bonanni, R; Carlesimo, G A; Caltagirone, C


    In people with cerebral palsy, severe neuromotor disability and communication problems make standard neuropsychological tests impossible. Therefore, alternative methods and specific aids must be developed to allow patients to autonomously respond to the examiner's questions. In the present individuals and study, a neuropsychological evaluation was made of a group of eight individuals with cerebral palsy, and severe neuromotor and verbal disabilities, and a group of 19 normal subjects matched for mental age. The tests were administered using an autonomous selection method in which the patient selects the various responses through specific aids without the examiner's interference. Patients' group performances in visuo-spatial and memory tests were on average lower than the mean of the control group. In the verbal domain, patients' scores were comparable to those of normal children in all tests but one assessing the comprehension of syntactically complex sentences. An analysis of the patients' individual performances also revealed heterogeneous cognitive profiles: some patients presented a homogeneously distributed cognitive impairment and others a more selective one. This finding is particularly important for planning differentiated learning programmes, and identifying suitable communicative instruments in rehabilitative and educational settings.

  15. Executive function deficits in pediatric cerebellar tumor survivors. (United States)

    Koustenis, Elisabeth; Hernáiz Driever, Pablo; de Sonneville, Leo; Rueckriegel, Stefan M


    Besides motor function the cerebellum subserves frontal lobe functions. Thus, we investigated executive functions in pediatric posterior fossa tumor survivors. We tested information processing, aspects of attention, planning and intelligence in 42 pediatric posterior fossa tumor survivors (mean age 14.63 yrs, SD 5.03). Seventeen low-grade tumor patients (LGCT) were treated with surgery only and 25 high-grade tumors patients (HGCT) received postsurgical adjuvant treatment. We evaluated simple reaction time, executive functioning, i.e. visuospatial memory, inhibition, and mental flexibility using the Amsterdam Neuropsychological Tasks program, whereas forward thinking was assessed with the Tower of London-test. Intelligence was determined using the Wechsler Intelligence Scale. Ataxia was assessed with the International Cooperative Ataxia Rating Scale. About one third of each patient group showed forward thinking scores below one standard deviation of the norm. Impaired forward thinking correlated significantly with degree of ataxia (r = -0.39, p = 0.03) but not with fluid intelligence. Both patient groups exhibited executive function deficits in accuracy and reaction speed in more difficult tasks involving information speed and attention flexibility. Still, HGCT patients were significantly slower and committed more errors. Working memory was inferior in HGCT patients. Pediatric cerebellar tumor survivors with different disease and treatment related brain damage exhibit similar patterns of impairment in executive functioning, concerning forward thinking, inhibition and mental flexibility. The deficits are larger in high-grade tumor patients. The pattern of function loss seen in both groups is most probably due to comparable lesions to cerebro-cerebellar circuits that are known to modulate critical executive functions.

  16. A Flexible and Integrated System for the Remote Acquisition of Neuropsychological Data in Stroke Research. (United States)

    Durisko, Corrine; McCue, Michael; Doyle, Patrick J; Dickey, Michael Walsh; Fiez, Julie A


    Neuropsychological testing is a central aspect of stroke research because it provides critical information about the cognitive-behavioral status of stroke survivors, as well as the diagnosis and treatment of stroke-related disorders. Standard neuropsychological methods rely upon face-to-face interactions between a patient and researcher, which creates geographic and logistical barriers that impede research progress and treatment advances. To overcome these barriers, we created a flexible and integrated system for the remote acquisition of neuropsychological data (RAND). The system we developed has a secure architecture that permits collaborative videoconferencing. The system supports shared audiovisual feeds that can provide continuous virtual interaction between a participant and researcher throughout a testing session. Shared presentation and computing controls can be used to deliver auditory and visual test items adapted from standard face-to-face materials or execute computer-based assessments. Spoken and manual responses can be acquired, and the components of the session can be recorded for offline data analysis. To evaluate its feasibility, our RAND system was used to administer a speech-language test battery to 16 stroke survivors with a variety of communication, sensory, and motor impairments. The sessions were initiated virtually without prior face-to-face instruction in the RAND technology or test battery. Neuropsychological data were successfully acquired from all participants, including those with limited technology experience, and those with a communication, sensory, or motor impairment. Furthermore, participants indicated a high level of satisfaction with the RAND system and the remote assessment that it permits. The results indicate the feasibility of using the RAND system for virtual home-based neuropsychological assessment without prior face-to-face contact between a participant and researcher. Because our RAND system architecture uses off

    Cheung, Lorraine L T; Wakefield, Claire E; Ellis, Sarah J; Mandalis, Anna; Frow, Eleanor; Cohn, Richard J


    As pediatric brain tumor survivors may experience cognitive decline post-treatment, a neuropsychology assessment is often conducted. The assessment evaluates the child's cognitive functioning and highlights potential challenges. Whilst neuropsychology reports provide recommendations for the home and school, how this translates in practice is under researched. This study explored parent and teacher understanding of neuropsychology reports, implementation rates for recommendations and their perceived effectiveness. Barriers to implementation were also investigated. Twenty-five semi-structured interviews were conducted with 17 parents and 8 teachers of childhood brain tumor survivors from 15 Australian families who had received a neuropsychology report within 2 years of the interview. Twenty-four neuropsychology reports encompassing 131 recommendations were reviewed. The qualitative methodological framework of Miles and Huberman [Miles M, Huberman A. Qualitative data analysis: An expanded sourcebook. London: Sage; 1994] was used to analyze interview transcripts with QSR NVivo 9.0. The majority of parents and teachers had a sound understanding of the report. Implementation of recommendations at home and school was 47% and 41%, respectively. Recommendations that did not require extra effort and organization appeared more likely to be implemented, however, those perceived to be more effective or helpful did not necessarily have higher implementation rates. Key reported barriers to implementation barrier were patient reluctance, and a lack of parents' willingness to adopt the recommendation. Patient understanding and willingness play a significant role in the implementation of neuropsychology recommendations. Collaboration and clear communication between the patient, teacher, parent, and neuropsychologist is vital for effective management. © 2014 Wiley Periodicals, Inc.

  18. Behavior, neuropsychology and fMRI. (United States)

    Bennett, Maxwell R; Hatton, Sean; Hermens, Daniel F; Lagopoulos, Jim

    Cognitive neuroscientists in the late 20th century began the task of identifying the part(s) of the brain concerned with normal behavior as manifest in the psychological capacities as affective powers, reasoning, behaving purposively and the pursuit of goals, following introduction of the 'functional magnetic resonance imaging' (fMRI) method for identifying brain activity. For this research program to be successful two questions require satisfactory answers. First, as the fMRI method can currently only be used on stationary subjects, to what extent can neuropsychological tests applicable to such stationary subjects be correlated with normal behavior. Second, to what extent can correlations between the various neuropsychological tests on the one hand, and sites of brain activity determined with fMRI on the other, be regarded as established. The extent to which these questions have yet received satisfactory answers is reviewed, and suggestions made both for improving correlations of neuropsychological tests with behavior as well as with the results of fMRI-based observations.

  19. Neurocognitive deficits and neuroimaging abnormalities are prevalent in children with lupus: clinical and research experiences at a US pediatric institution. (United States)

    Muscal, E; Bloom, D R; Hunter, J V; Myones, B L


    Neurocognitive impairments and neuroimaging abnormalities are frequently observed in adults with systemic lupus erythematosus. There is a paucity of similar data in childhood-onset disease. We hypothesized that neurocognitive and neuroimaging abnormalities would be prevalent in children undergoing neuropsychological evaluations. We reviewed patient neurocognitive evaluations performed at a large United States pediatric institution during the period 2001 to 2008. Records were retrieved from 24 children referred to neuropsychology due to clinical indications. Data from 15 children enrolled in a prospective structure-function association study were also analyzed. Subjects were predominantly African-American and Hispanic adolescent girls of average intelligence. aPL positivity and aspirin use was prevalent. Neurocognitive impairment was designated in 70.8% of retrospective, and 46.7% of prospective cohort patients. Deficits were seen at times of wellness, without previous neuropsychiatric lupus, and early in disease courses. Scores >1.5 standard deviations below published age-matched norms were common in tests of executive functioning, visual memory and visual-spatial planning. Features of depression were seen in 33.3% of the children in the retrospective cohort (clinical referrals). Cerebral and cerebellar volume loss was observed in a majority of blinded prospective cohort research magnetic resonance images (73.3% and 67.7% respectively). White matter hyperintensities were observed in retrospective and prospective cohort magnetic resonance images (36.6% and 46.7% respectively). Larger prospective studies that elucidate structure-function associations in children with systemic lupus erythematosus are planned.

  20. Towards reporting standards for neuropsychological study results: A proposal to minimize communication errors with standardized qualitative descriptors for normalized test scores. (United States)

    Schoenberg, Mike R; Rum, Ruba S


    Rapid, clear and efficient communication of neuropsychological results is essential to benefit patient care. Errors in communication are a lead cause of medical errors; nevertheless, there remains a lack of consistency in how neuropsychological scores are communicated. A major limitation in the communication of neuropsychological results is the inconsistent use of qualitative descriptors for standardized test scores and the use of vague terminology. PubMed search from 1 Jan 2007 to 1 Aug 2016 to identify guidelines or consensus statements for the description and reporting of qualitative terms to communicate neuropsychological test scores was conducted. The review found the use of confusing and overlapping terms to describe various ranges of percentile standardized test scores. In response, we propose a simplified set of qualitative descriptors for normalized test scores (Q-Simple) as a means to reduce errors in communicating test results. The Q-Simple qualitative terms are: 'very superior', 'superior', 'high average', 'average', 'low average', 'borderline' and 'abnormal/impaired'. A case example illustrates the proposed Q-Simple qualitative classification system to communicate neuropsychological results for neurosurgical planning. The Q-Simple qualitative descriptor system is aimed as a means to improve and standardize communication of standardized neuropsychological test scores. Research are needed to further evaluate neuropsychological communication errors. Conveying the clinical implications of neuropsychological results in a manner that minimizes risk for communication errors is a quintessential component of evidence-based practice.

  1. Distinct Neuropsychological Correlates of Cognitive, Behavioral, and Affective Apathy Sub-Domains in Acquired Brain Injury (United States)

    Njomboro, Progress; Deb, Shoumitro


    Apathy has a high prevalence and a significant contribution to treatment and rehabilitation outcomes in acquired brain damage. Research on the disorder’s neuropsychological correlates has produced mixed results. While the mixed picture may be due to the use of varied assessment tools on different patient populations, it is also the case that most studies treat apathy as a unitary syndrome. This is despite the evidence that apathy is a multifaceted and multidimensional syndrome. This study investigates the neuropsychological correlates of apathy in 49 patients with acquired brain damage. It further fractionates apathy symptoms into affective, cognitive, and behavioral sub-domains and investigates their individual relations with standard measures of affective, cognitive, and behavioral functioning. Global apathy scores were not related to any of these measures. Affective apathy was associated with emotion perception deficits, and cognitive apathy was associated with executive deficits on the Brixton test. These results demonstrate that treating apathy as a single entity may hide important correlates to apathy symptoms that become visible when the disorder is fractionated into its sub-domains. The study highlights the research and clinical importance of treating apathy as a multidimensional syndrome. PMID:24904518

    Objective: Neurocognitive impairments have been documented in adolescents with early-onset schizophrenia (EOS). There is still inconsistency regarding an average profile, which could be due to the fact that each study uses different tests. The purpose of this study was to examine whether the “Measurement and Treatment Research to Improve Cognition in Schizophrenia” (MATRICS) battery is useful in detecting differences between the patient group and the healthy controls, and to describe the neuropsychological pattern in the EOS group. Method: Neuropsychological functioning was examined in 31 adolescents with schizophrenia spectrum disorders and 67 healthy controls, using the MATRICS battery. Results: There were significant differences between the patients and the controls on every domain except for social cognition. Patients showed a generalized neurocognitive deficit of 0.8–1.8 SDs compared with controls, with verbal learning, working memory, and visual learning being the most affected areas. Conclusions: The MATRICS battery is sensitive in detecting differences between patients and controls in the adolescent population. However, we question the use of Mayer-Salovey-Caruso Emotional Intelligence Test in this age group. Results document a significant generalized deficit in adolescents with EOS. PMID:19223656

    Full Text Available The impairment of  gesture and pantomime in aphasia was examined from  a neuropsychological perspective. The Boston Diagnostic Test of  Aphasia, Luria's Neuro-psychological Investigation, Pickett's Tests for  gesture and pantomime and the Performance Scale of  the Wechsler Adult Intelligence Scale were administered to six aphasic subjects with varying etiology and severity. Results indicated that severity of  aphasia was positively related to severity of  gestural disturbance; gestural ability was associated with verbal and non-linguistic aspects of  ability, within receptive and expressive levels respectively; performance  on gestural tasks was superior to that on verbal tasks irrespective of  severity of aphasia; damage to Luria's second and third functional  brain units were positively related to deficits  in receptive and expressive gesture respectively; no relationship was found  between seventy of  general intellectual impairment and gestural deficit.  It was concluded that the gestural impairment may best be understood as a breakdown in complex sequential manual motor activity. Theoretical and therapeutic implications were discussed.

    Full Text Available Apathy has a high prevalence and a significant contribution to treatment and rehabilitation outcomes in acquired brain damage. Research on the disorder’s neuropsychological correlates has produced mixed results. While the mixed picture may be due to the use of varied assessment tools on different patient populations, it’s also the case that most studies treat apathy as a unitary syndrome. This is in spite of evidence that apathy is a multifaceted and multidimensional syndrome. This study investigates the neuropsychological correlates of apathy in 49 patients with acquired brain damage. It further fractionates apathy symptoms into affective, cognitive and behavioural sub-domains, and investigates their individual relations with standard measures of affective, cognitive and behavioural functioning. Global apathy scores were not related to any of these measures. Affective apathy was associated with emotion perception deficits, and cognitive apathy was associated with executive deficits on the Brixton test. These results demonstrate that treating apathy as a single entity may hide important correlates to apathy symptoms that become visible when the disorder is fractionated into its sub-domains. The study highlights the research and clinical importance of treating apathy as a multidimensional syndrome.
