    The American Medical Association Current Procedural Panel developed a new billing code making behavioral health screening a reimbursable healthcare service. The use of computerized testing as a means for cognitive screening and brief cognitive testing is increasing at a rapid rate. The purpose of this education paper is to provide information to clinicians, healthcare administrators, and policy developers about the purpose, strengths, and limitations of cognitive screening tests versus comprehensive neuropsychological evaluations. Screening tests are generally brief and narrow in scope, they can be administered during a routine clinical visit, and they can be helpful for identifying individuals in need of more comprehensive assessment. Some screening tests can also be helpful for monitoring treatment outcomes. Comprehensive neuropsychological assessments are multidimensional in nature and used for purposes such as identifying primary and secondary diagnoses, determining the nature  and severity of a person's cognitive difficulties, determining functional limitations, and planning treatment and rehabilitation. Cognitive screening tests are expected to play an increasingly important role in identifying individuals with cognitive impairment and in determining which individuals should be referred for further neuropsychological assessment. However, limitations of existing cognitive screening tests are present and cognitive screening tests should not be used as a replacement for comprehensive neuropsychological testing. © The Author 2017.

    Existing batteries for FMRI do not precisely meet the criteria for comprehensive mapping of cognitive functions within minimum data acquisition times using standard scanners and head coils. The goal was to develop a battery of neuropsychological paradigms for FMRI that can also be used in other brain imaging techniques and behavioural research. Participants were 61 healthy, young adult volunteers (48 females and 13 males, mean age: 22.25 ± 3.39 years) from the university community. The battery included 8 paradigms for basic (visual, auditory, sensory-motor, emotional arousal) and complex (language, working memory, inhibition/interference control, learning) cognitive functions. Imaging was performed using standard functional imaging capabilities (1.5-T MR scanner, standard head coil). Structural and functional data series were analysed using Brain Voyager QX2.9 and Statistical Parametric Mapping-8. For basic processes, activation centres for individuals were within a distance of 3-11 mm of the group centres of the target regions and for complex cognitive processes, between 7 mm and 15 mm. Based on fixed-effect and random-effects analyses, the distance between the activation centres was 0-4 mm. There was spatial variability between individual cases; however, as shown by the distances between the centres found with fixed-effect and random-effects analyses, the coordinates for individual cases can be used to represent those of the group. The findings show that the neuropsychological brain mapping battery described here can be used in basic science studies that investigate the relationship of the brain to the mind and also as functional localiser in clinical studies for diagnosis, follow-up and pre-surgical mapping. © 2013.

  3. Neuropsychological deficits in temporal lobe epilepsy: A comprehensive review

    Full Text Available Temporal lobe epilepsy (TLE is the most prevalent form of complex partial seizures with temporal lobe origin of electrical abnormality. Studies have shown that recurrent seizures affect all aspects of cognitive functioning, including memory, language, praxis, executive functions, and social judgment, among several others. In this article, we will review these cognitive impairments along with their neuropathological correlates in a comprehensive manner. We will see that neuropsychological deficits are prevalent in TLE. Much of the effort has been laid on memory due to the notion that temporal lobe brain structures involved in TLE play a central role in consolidating information into memory. It seems that damage to the mesial structure of the temporal lobe, particularly the amygdale and hippocampus, has the main role in these memory difficulties and the neurobiological plausibility of the role of the temporal lobe in different aspects of memory. Here, we will cover the sub-domains of working memory and episodic memory deficits. This is we will further proceed to evaluate the evidences of executive function deficits in TLE and will see that set-shifting among other EFs is specifically affected in TLE as is social cognition. Finally, critical components of language related deficits are also found in the form of word-finding difficulties. To conclude, TLE affects several of cognitive function domains, but the etiopathogenesis of all these dysfunctions remain elusive. Further well-designed studies are needed for a better understanding of these disorders.

    Abstract The prevalence of cognitive impairment and orthostatic hypotension (OH) increases with age, but the results of studies that assessed possible associations between them are inconsistent. The aim of this study is to assess possible associations between cognitive impairment and OH in patients ≥65 years of age who underwent a comprehensive geriatric assessment. A retrospective analysis was conducted of the computerized medical records of the study population from 2005 to 2013. Data collected included blood pressure measurements that enabled the calculation of OH, results of the mini-mental state examination (MMSE), results of the Montreal cognitive assessment (MoCA) test, and cognitive diagnoses that were determined over the course of the assessment. The rate of OH in the study population of 571 adults was 32.1%. The mean MMSE score was 22.5 ± 5.2 among participants with OH and 21.6 ± 5.8 among those without OH (P = 0.09). The absence of a significant association between OH and MMSE remained after adjusting the MMSE score for age and education level. The mean MoCA score was 16.4 ± 5.0 among participants with OH and 16.4 ± 4.8 among those without (P = 0.33). The prevalence of OH was 39% among participants without cognitive impairment, 28.9% among those with mild cognitive impairment (MCI), and 30.6% among those with dementia (P = 0.13). There was no association between OH and cognitive impairment in adults who underwent a comprehensive geriatric assessment. PMID:27442658

    2018-01-01

    This investigation was designed to determine the predictive accuracy of a comprehensive neuropsychological and brief neuropsychological test battery with regard to the capacity to perform instrumental activities of daily living (IADLs). Accuracy statistics that included measures of sensitivity, specificity, positive and negative predicted power and positive likelihood ratio were calculated for both types of batteries. The sample was drawn from a general neurological group of adults (n = 117) that included a number of older participants (age >55; n = 38). Standardized neuropsychological assessments were administered to all participants and were comprised of the Halstead Reitan Battery and portions of the Wechsler Adult Intelligence Scale-III. A comprehensive test battery yielded a moderate increase over base-rate in predictive accuracy that generalized to older individuals. There was only limited support for using a brief battery, for although sensitivity was high, specificity was low. We found that a comprehensive neuropsychological test battery provided good classification accuracy for predicting IADL capacity.

  6. The neuropsychology of narrative: story comprehension, story production and their interrelation.

    2004-01-01

    Stories are used extensively for human communication; both the comprehension and production of oral and written narratives constitute a fundamental part of our experience. While study of this topic has largely been the domain of cognitive psychology, neuroscience has also made progress in uncovering the processes underlying these abilities. In an attempt to synthesize work from both literatures, this review: (1) summarizes the current neuroimaging and patient research pertaining to narrative comprehension and production, (2) attempts to integrate this information with the processes described by the discourse models of cognitive psychology, and (3) uses this information to examine the possible interrelation between comprehension and production. Story comprehension appears to entail a network of frontal, temporal and cingulate areas that support working-memory and theory-of-mind processes. The specific functions associated with these areas are congruent with the processes proposed by cognitive models of comprehension. Moreover, these same areas appear necessary for story production, and the causal-temporal ordering of selected information may partially account for this common ground. A basic description of comprehension and production based solely on neuropsychological evidence is presented to complement current cognitive models, and a number of avenues for future research are suggested.

    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.

    To contrast subjective and objective measures of neuropsychological health in F-111 aircraft Deseal/Reseal maintenance personnel, against two appropriate comparison groups. Exposed and comparison participants completed a postal questionnaire which included a validated memory questionnaire and additional questions relating to possible cognitive symptoms. They also underwent a comprehensive neuropsychological assessment and screening for a past or current disturbance of mood. Multiple linear or logistic regression was conducted for each outcome using exposure group and potential confounders as explanatory variables. There was a strong and consistent excess of self-reported cognitive problems among the exposed group relative to the comparison groups including a 2.8-4.3-fold increase in self-reported symptoms of forgetfulness, loss of concentration and difficulty finding the right word. On detailed neuropsychological testing, the exposed group performed significantly worse than comparisons on tests of psychomotor speed, executive functioning, and new learning/memory. These findings could not be accounted for by disturbances of mood or other potential confounders. There was a strong and consistent increase in self-reported cognitive problems among the exposed, and small but significant exposure-specific differences on objective tests of cognitive functioning. The findings are consistent with the development of adverse neuropsychiatric changes related to occupational exposure to solvents.

    2014-01-01

    Full Text Available The aim of this study was to identify the neuropsychological characteristics of dyslexic children. Seventy-three children underwent neuropsychological assessment and were divided into two groups: a group with dyslexia (DG; n=39 and a control group (CG; n= 34. A general linear model showed a significant difference between the groups regarding the following abilities: reading, writing and mathematics; forward and backward digit span tasks; semantic and phonological fluency; number of completed categories and total number of cards in the Wisconsin Cards Sorting Test; as well as right and left discrimination on self and on other. These results suggest impairment in executive functions, phonological working memory and semantic memory among dyslexic children, rather than impairment of just phonological abilities, as suggested in previous studies.

  11. Cognitive impairment in depressive disorders. Neuropsychological evaluation of memory and behavioural disturbances.

    Emilien, G; Penasse, C; Waltregny, A

    1998-01-01

    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.

  12. International growth of neuropsychology.

    2017-11-01

    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.

  13. Ecological validity of neuropsychological assessment and perceived employability.

    Wen, Johnny H; Boone, Kyle; Kim, Kevin

    2006-11-01

    Ecological validity studies that have examined the relationship between cognitive abilities and employment in psychiatric and medical populations have found that a wide range of cognitive domains predict employability, although memory and executive skills appear to be the most important. However, no information is available regarding a patient's self-perceived work attributes and objective neuropsychological performance, and whether the same cognitive domains associated with successful employment are also related to a patient's self-perception of work competence. In the present study, 73 medical and psychiatric patients underwent comprehensive neuropsychological assessment. Step-wise multiple regression analyses revealed that the visual-spatial domain was the only significant predictor of self-perceived work attributes and work competence as measured by the Working Inventory (WI) and the Work Adjustment Inventory (WAI), accounting for 7% to 10% of inventory score variability. The results raise the intriguing possibility that targeting of visual spatial skills for remediation and development might play a separate and unique role in the vocational rehabilitation of a lower SES population, specifically, by leading to enhanced self-perception of work competence as these individuals attempt to enter the job market.

    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.

    2016-11-01

    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.

    Cases of thallium poisoning are rare and neuropsychological assessment has only been reported in detail in one other case. In the case reported here, neuropsychological assessments were carried out three, 12, and 54 months after diagnosis of thallium poisoning in a man who had acutely shown a number of neurological signs including confusion and disorientation and generalised slowing of EEG which was more prominent on the left. Evidence suggested that he had been exposed to thallium over a period of weeks. Neuropsychological assessment indicated an unexpected weakness in verbal abilities which persisted. This finding is consistent with the only other published case report which details neuropsychological effects after a single large dose of thallium and which also found a lateralised impairment.

    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.

    equally well in children with TS. The available body of scientific evidence suggests that persons with TS have normally distributed intellectual ability. This would suggest a diminished role for routine IQ testing unless there is compelling clinical evidence to suggest that the IQ score be obtained, such as when the individual is suspected of having an LD. Given that children with TS may be particularly at risk for learning disabilities or academic deficiencies in math and written language, a complete psychoeducational workup should be conducted on any child with TS who is suspected of having such difficulties. This evaluation should be conducted as early as possible, so that educational interventions can be implemented. Traditionally, the psychoeducational evaluation is performed by the school psychologist and should include standardized IQ assessment and academic achievement testing that can objectively identify and quantify the nature and severity of the learning problem. Once the problem has been documented, the school psychologist should recommend appropriate educational and remedial interventions. In addition to psychoeducational testing, neuropsychological testing is indicated to identify specific cognitive deficits that might be present in children with TS, notably problems with visuomotor integration, motor skill, and executive function. The psychoeducational evaluation performed by the school psychologist typically does not assess these cognitive functions. Therefore, referral for neuropsychological testing is indicated if there is a strong clinical suspicion of cognitive deficits. The accumulated neuropsychological literature in TS suggests that a broad-based, comprehensive, and lengthy neuropsychological examination is not necessary, however. At a minimum, the neuropsychological test battery should include assessment of visuomotor integration ability, motor skills, spatial/perceptual abilities, and executive function. This type of assessment would take less

    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.

    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.

  7. The neuropsychology of autism.

    Happé, F; Frith, U

    1996-08-01

    In this review, we aim to bring together major trends in autism research at three levels: biology, behaviour and cognition. We propose that cognitive theories are vital in neuropsychology, which seeks to make connections between brain abnormality and behavioural symptoms. Research at each of the three levels is incomplete, but important advances have been made. At the biological level, there is strong evidence for genetic factors, although the mechanism is, as yet, unknown. At the behavioural level, diagnosis and education are becoming more coherent and less controversial, although the possibility of autism subtypes has provoked new debate. At the cognitive level, three major theories are proving fruitful (mentalizing impairment, executive dysfunction and weak central coherence), although the relation and overlap between these is uncertain. Rapidly advancing technology and methodology (e.g. brain imaging, gene mapping), as tools of cognitive theory, may help to make autism one of the first developmental disorders to be understood at the neuropsychological level.

    Full Text Available This article presents the results of neuropsychological studies of the patients with neurosarcoidosis. The obtained results show that typical manifestations of neurosarcoidosis are disorders of motor functions. They appear in the speed reduction of actions and their accuracy, which prove peripheral neuropathy and myopathy at the functional level as clinical signs of neurosarcoidosis. Specific manifestations of neurosarcoidosisare determinedby topographical localization of granulomatoma.

    Full Text Available ABSTRACT. The article reviews the history of neuropsychological rehabilitation. It begins with the description of first rehabilitation programs developed by Paul Broca and Shepherd Franz. Franz’s experimental work for motor recovery in monkeys and correlation between active movement or affected limb immobilization and rehabilitation outcomes are described in further details. Special focus is given on ideas of famous German neurologist and psychiatrist Kurt Goldstein, who laid the foundation for modern approach in rehabilitation. Goldstein developed the idea of connection between rehabilitation and patient’s daily life. He also pointed out the necessity of psychological care of patients with brain damage.Russian neuropsychological approach is presented by its founders L.S. Vygotskiy and A.R. Luriya. Aspects of higher mental processes structure and options of its correction such as “cognitive prosthesis” are described in the sense of the approach.Y. Ben-Yishay, G. Prigatano, B. Wilson represent neuropsychological rehabilitation of the second half of the 20th century. The idea of a holistic approach for rehabilitation consists of such important principles as patient’s active involvement in a process of rehabilitation, work of a special team of rehabilitation professionals, inclusion of patient’s family members. The short review of a new rehabilitation approach for patients in coma, vegetative states and critical patients under resuscitation is given.

    2018-05-01

    This work aimed to review main competency requirements from training models in countries with well-established specialties in clinical neuropsychology and to extract core competencies that likely will apply to clinical neuropsychologists regardless of regional and cultural context. We reviewed standards for post-graduate training in clinical neuropsychology from countries in Europe, Australia, and North America based on existing literature, presentations at international conferences, and from description of the training models from national psychological or neuropsychological associations. Despite differences, the reviewed models share similar core competencies considered necessary for a specialty in clinical neuropsychology: (1) In-depth knowledge of general psychology including clinical psychology (post-graduate level), ethical, and legal standards. (2) Expert knowledge about clinically relevant brain-behavioral relationships. (3) Comprehensive knowledge about, and skills in, related clinical disciplines. (4) In-depth knowledge about and skills in neuropsychological assessment, including decision-making and diagnostic competency according to current classification of diseases. (5) Competencies in the area of diversity and culture in relation to clinical neuropsychology. (6) Communication competency of neuropsychological findings and test results to relevant and diverse audiences. (7) Knowledge about and skills in psychological and neuropsychological intervention, including treatment and rehabilitation. All the models have undergone years of development in accordance with requirements of national health care systems in different parts of the world. Despite differences, the common core competency requirements across different regions of the world suggest generalizability of these competencies. We hope this summary can be useful as countries with less established neuropsychology training programs develop their models.

    The Discriminant Equation (DE) represents a recently developed system for screening neuropsychological abnormality in older children. The DE was subjected to cross-validation on a sample of 82 child and adolescent psychiatric patients referred for a comprehensive neuropsychological assessment. An overall hit rate of 79.3% correct classification was found which supported the validity of the DE in predicting neuropsychological impairment. The findings are discussed in relation to population characteristics and the nature of the criterion to be predicted as they may affect the application of neuropsychological screening procedures.

  15. Vygotsky in applied neuropsychology

    Directory of Open Access Journals (Sweden)

    Glozman J. M.

    2016-12-01

    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.

  16. Lying in neuropsychology.

    2014-10-01

    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.

  17. The neuropsychology of hallucinations

    Directory of Open Access Journals (Sweden)

    Pavlović D.M.

    2011-01-01

    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.

    Surveys of practicing neuropsychologists have been conducted for years; however, there have been no comprehensive surveys of neuropsychology trainees, which may result in important issues being overlooked by the profession. This survey assessed trainees' experiences in areas such as student debt, professional development, and training satisfaction. Survey items were written by a task force of the AACN Student Affairs Committee (SAC), and neuropsychology trainees were recruited via neuropsychology-focused listservs. In total, 344 trainees completed the survey (75% female) and included participants from every region of the US and Canada. Based on the survey questions, nearly half of all trainees (47%) indicated financial factors were the greatest limitation in their training. Student debt had a bimodal distribution; 32.7% had minimal debt, but 45% had debt >$100,000. In contrast, expected starting salaries were modest, but consistent with findings ($80-100,000). While almost all trainees intended to pursue board certification (97% through ABPP), many were 'not at all' or only 'somewhat' familiar with the process. Results indicated additional critical concerns beyond those related to debt and lack of familiarity with board certification procedures. The results will inform SAC conference programming and the profession on the current 'state of the trainees' in neuropsychology.

  19. Neuropsychological Mechanisms for Falls in Older Adults

    Directory of Open Access Journals (Sweden)

    Yu eLiu

    2014-04-01

    Full Text Available Falls, a common cause of injury among older adults, have become increasingly prevalent. As the world’s population ages, the increase in – and the prevalence of – falls among older people makes this a serious and compelling societal and healthcare issue. Physical weakness is a critical predictor in falling. While considerable research has examined this relationship, comprehensive reviews of neuropsychological predictors of falls have been lacking. In this paper, we examine and discuss current studies of the neuropsychological predictors of falls in older adults, as related to sporting and non-sporting contexts. By integrating the existing evidence, we propose that brain aging is an important precursor of the increased risk of falls in older adults. Brain aging disrupts the neural integrity of motor outputs and reduces neuropsychological abilities. Older adults may shift from unconscious movement control to more conscious or attentive motor control. Increased understanding of the causes of falls will afford opportunities to reduce their incidence, reduce consequent injuries, improve overall well-being and quality of life, and possibly to prolong life.

    2015-05-01

    Full Text Available The aim of this review is to discuss the basic forms of neuropsychological rehabilitation for patients with traumatic brain injury (TBI. More broadly, we discussed cognitive rehabilitation therapy (CRT which constitutes a fundamental component in therapeutic interaction at many centres worldwide. Equally presented is a comprehensive model of rehabilitation, the fundamental component of which is CRT. It should be noted that the principles of this approach first arose in Poland in the 1970s, in other words, several decades before their appearance in other programmemes. Taken into consideration are four factors conditioning the effectiveness of such a process: comprehensiveness, earlier interaction, universality and its individualized character. A comprehensive programmeme of rehabilitation covers: cognitive rehabilitation, individual and group rehabilitation with the application of a therapeutic environment, specialist vocational rehabilitation, as well as family psychotherapy. These training programmemes are conducted within the scope of the ‘Academy of Life,’ which provides support for the patients in their efforts and shows them the means by which they can overcome existing difficulties. Equally emphasized is the close cooperation of the whole team of specialists, as well as the active participation of the family as an essential condition for the effectiveness of rehabilitation and, in effect, a return of the patient to a relatively normal life. Also presented are newly developing neurothechnologies and the neuromarkers of brain injuries. This enables a correct diagnosis to be made and, as a result, the selection of appropriate methods for neuropsychological rehabilitation, including neurotherapy.

    The objective was to analyze neuropsychological testing data from 15 patients before and after stereotactic laser ablation surgery for temporal lobe epilepsy and to describe the seizure outcomes after stereotactic laser ablation surgery. A retrospective review of 15 patients who underwent stereotactic laser ablation and who also underwent neuropsychological testing before and after surgery was performed. Verbal and visual memory was assessed in all 15 patients using California Verbal Learning Test and Wechsler Memory Scale IV. Naming was assessed in 9 of 15 patients using the Boston Naming Test. Statistical analysis was performed to determine clinically significant changes using previously validated reliable change indices and proprietary Advanced Clinical Solutions software. Seizure outcome data were evaluated using Engel classification. Postsurgery neuropsychological evaluation demonstrated that all 15 patients experienced at least 1 clinically significant decline in either verbal or visual memory. Ten patients in this series, including five with dominant-hemisphere surgery, demonstrated decline in delayed memory for narrative information (Logical Memory II). By contrast, the Boston Naming Test demonstrated more favorable results after surgery. Two of nine patients demonstrated a clinically significant increase in naming ability, and only one of nine patients demonstrated a clinically significant decline in naming ability. With at least 6months of follow-up after surgery, 33% reported seizure freedom. Stereotactic laser ablation can result in clinically significant and meaningful decline in verbal and visual memory when comparing patients to their own presurgical baseline. Naming ability, conversely, is much less likely to be impacted by stereotactic laser ablation and may improve after the procedure. Copyright © 2017 Elsevier Inc. All rights reserved.

    2012-07-16

    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.

    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.

    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.

    2018-01-01

    Computational theories of brain function have become very influential in neuroscience. They have facilitated the growth of formal approaches to disease, particularly in psychiatric research. In this paper, we provide a narrative review of the body of computational research addressing neuropsychological syndromes, and focus on those that employ Bayesian frameworks. Bayesian approaches to understanding brain function formulate perception and action as inferential processes. These inferences combine 'prior' beliefs with a generative (predictive) model to explain the causes of sensations. Under this view, neuropsychological deficits can be thought of as false inferences that arise due to aberrant prior beliefs (that are poor fits to the real world). This draws upon the notion of a Bayes optimal pathology - optimal inference with suboptimal priors - and provides a means for computational phenotyping. In principle, any given neuropsychological disorder could be characterized by the set of prior beliefs that would make a patient's behavior appear Bayes optimal. We start with an overview of some key theoretical constructs and use these to motivate a form of computational neuropsychology that relates anatomical structures in the brain to the computations they perform. Throughout, we draw upon computational accounts of neuropsychological syndromes. These are selected to emphasize the key features of a Bayesian approach, and the possible types of pathological prior that may be present. They range from visual neglect through hallucinations to autism. Through these illustrative examples, we review the use of Bayesian approaches to understand the link between biology and computation that is at the heart of neuropsychology.

  6. Methodologic Issues in Neuropsychological Testing

    2001-01-01

    Objective: To familiarize athletic trainers with methodologic issues regarding the development and implementation of neuropsychological tests used in programs for monitoring sport-related cerebral concussion. Data Sources: Knowledge base and MEDLINE and PsychLit searches from 1980–2000 using the terms sports, athletes, concussion, and brain. Data Synthesis: Neuropsychological testing is a proven method for evaluating symptoms of concussion that results from a variety of different causes. These tests have been shown to be effective in evaluating symptoms of subtle cognitive dysfunction in a number of patient groups. Applying these tests in an athletic population has required some procedural modifications, including the use of brief test batteries, collection of preseason baseline data, and evaluation of subtle postconcussive changes in test scores over time. New methods are now being used for improved evaluation of the reliability and validity of neuropsychological tests in athletes. Proper scientific analysis of the psychometric properties of neuropsychological tests and the ultimate value of their use in the sport setting will require years of detailed study on large numbers of athletes with and without symptoms of concussion. Conclusions/Recommendations: Athletic trainers and related personnel need to be aware of the training and methodologic issues associated with neuropsychological testing. Knowledge of the scientific properties of these tests, their advantages, and current limitations will ultimately enhance the athletic trainer's ability to use information from neuropsychological testing in an effective manner.

    2015-06-01

    Reliable change indices (RCIs) and standardized regression-based (SRB) change score norms permit evaluation of meaningful changes in test scores following treatment interventions, like epilepsy surgery, while accounting for test-retest reliability, practice effects, score fluctuations due to error, and relevant clinical and demographic factors. Although these methods are frequently used to assess cognitive change after epilepsy surgery in adults, they have not been widely applied to examine cognitive change in children with epilepsy. The goal of the current study was to develop RCIs and SRB change score norms for use in children with epilepsy. Sixty-three children with epilepsy (age range: 6-16; M=10.19, SD=2.58) underwent comprehensive neuropsychological evaluations at two time points an average of 12 months apart. Practice effect-adjusted RCIs and SRB change score norms were calculated for all cognitive measures in the battery. Practice effects were quite variable across the neuropsychological measures, with the greatest differences observed among older children, particularly on the Children's Memory Scale and Wisconsin Card Sorting Test. There was also notable variability in test-retest reliabilities across measures in the battery, with coefficients ranging from 0.14 to 0.92. Reliable change indices and SRB change score norms for use in assessing meaningful cognitive change in children following epilepsy surgery are provided for measures with reliability coefficients above 0.50. This is the first study to provide RCIs and SRB change score norms for a comprehensive neuropsychological battery based on a large sample of children with epilepsy. Tables to aid in evaluating cognitive changes in children who have undergone epilepsy surgery are provided for clinical use. An Excel sheet to perform all relevant calculations is also available to interested clinicians or researchers. Copyright © 2015 Elsevier Inc. All rights reserved.

    2016-11-01

    This paper describes the development and practice of clinical neuropsychology in Australia. Clinical Neuropsychology has shown rapid growth in Australia over the past three decades. Comprehensive and specialized training programs are producing high quality graduates who are employed in a broad range of settings or private practice. Australia now has a substantial number of clinical neuropsychologists with specialist training. Whilst the majority of Australian clinical neuropsychologists still undertake assessment predominantly, there are growing opportunities for clinical neuropsychologists in rehabilitation and in a broad range of research contexts. Cultural issues relating to the assessment of Indigenous Australians and immigrants from many countries present significant challenges. Some major contributions have been made in the realms of test development and validation across various age groups. Australian clinical neuropsychologists are also contributing significantly to research in the fields of traumatic brain injury, aging and dementias, epilepsy, memory assessment, rehabilitation, substance abuse, and other psychiatric disorders. Expansion of roles of clinical neuropsychologists, in domains such as rehabilitation and research is seen as essential to underpin continuing growth of employment opportunities for the profession.

    2015-01-01

    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. 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. 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 the severity level varies from person to person. Like the

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.

    This study investigated the neuropsychologic functioning in nonclinical individuals with schizotypal traits using a comprehensive battery of neuropsychologic tests. We measured the neuropsychologic functioning of individuals with psychometrically defined nonclinical schizotypy (n = 28) and healthy controls (n = 31) for verbal memory (the Korean version of the California Verbal Learning Test), nonverbal memory (the Rey-Osterrieth Complex Figure Test), executive function (the Wisconsin Card Sorting Test), and attention (the d2 Test, Trail Making Test, and Controlled Oral Word Association Test). The schizotypal trait group committed significantly more total and perseverative errors and completed fewer categories on the Wisconsin Card Sorting Test than the control group. Performance on the other neuropsychologic tests did not differ between groups. The nonclinical individuals with schizotypal traits demonstrated executive dysfunction, showing decreased ability in conceptualization, use of cues, and mental flexibility. Furthermore, these results indicate that the cognitive deficits observed in schizophrenia are also a characteristic of nonclinical individuals with schizotypal traits. Copyright © 2011 Elsevier Inc.

    Previous studies found changes in regional cerebral blood flow (rCBF) patterns related to both age and various cognitive tasks. However, no study has yet demonstrated a relationship between rCBF and performance on the Luria-Nebraska Neuropsychological Battery (LNNB) in an elderly group. Seventy-nine elderly volunteers (56-88 years old), both healthy and demented, underwent the 133 xenon inhalation rCBF procedure and were given the LNNB. The decrements in the gray-matter blood flow paralleled decrements in performance on the LNNB. Using partial correlations, a significant proportion of shared variance was observed between gray-matter blood flow and the LNNB scales. However, there was much less of a relationship between white-matter blood flow and performance on the LNNB. This study suggests that even within a restricted age sample rCBF is related in a global way to neuropsychological functioning

    Tests of visuospatial function are often administered in comprehensive neuropsychological evaluations. These tests are generally considered assays of parietal lobe function; however, the neural correlates of these tests, using modern imaging techniques, are not well understood. In the current study we investigated the relationship between three commonly used tests of visuospatial function and lobar cortical thickness in each hemisphere. Data from 374 patients who underwent a neuropsychological evaluation and MRI scans in an outpatient dementia clinic were included in the analysis. We examined the relationships between cortical thickness, as assessed with Freesurfer, and performance on three tests: Judgment of Line Orientation (JoLO), Block Design (BD) from the Fourth edition of the Wechsler Adult Intelligence Scale, and Brief Visuospatial Memory Test-Revised Copy Trial (BVMT-R-C) in patients who showed overall average performance on these tasks. Using a series of multiple regression models, we assessed which lobe's overall cortical thickness best predicted test performance. Among the individual lobes, JoLO performance was best predicted by cortical thickness in the right temporal lobe. BD performance was best predicted by cortical thickness in the right parietal lobe, and BVMT-R-C performance was best predicted by cortical thickness in the left parietal lobe. Performance on constructional tests of visuospatial function appears to correspond best with underlying cortical thickness of the parietal lobes, while performance on visuospatial judgment tests appears to correspond best to temporal lobe thickness. Future research using voxel-wise and connectivity techniques and including more diverse samples will help further understanding of the regions and networks involved in visuospatial tests.

  6. Neuropsychological functioning in late-life depression

    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

    Narcolepsy with cataplexy is a severely disabling disorder very often arising in childhood. Data on neuropsychological impairment in children are scant. We administered standardized neuropsychological tests to 13 children with narcolepsy with cataplexy. Overall, our patients displayed multiple patterns of cognitive and behavioral dysfunction, and often academic failure (7 cases out of 13). All children had a normal full intelligence quotient (IQ), but 3 patients presented a significantly higher and 2 a significantly lower Verbal IQ compared to Performance IQ, respectively. Mean sleep latency was significantly correlated (P academic failure, despite the normal IQ. These children also have a certain psychopathological risk. All this seems to be at least partially detached from the direct effects of daytime sleepiness. © The Author(s) 2013.

    Filippini, Melissa; Arzimanoglou, Alexis; Gobbi, Giuseppe

    2013-11-01

    The International League Against Epilepsy (ILAE) Commission report on classification and terminology indicates that "diagnosing an individual as having an encephalopathic course requires demonstration of a failure to develop as expected relative to the same-aged peers or to regress in abilities." In this chapter, basing our discussion on the theoretical framework of neuroconstructivism, on the latest results deriving from functional neuroimaging and on the concept of system epilepsy, we use continuous spike-waves during slow-wave sleep (CSWS) as an example of how non-rapid eye movement (NREM) sleep spikes interfere with the organization and consolidation of neuropsychological networks in the sensitive phase of development, affecting also interconnected systems. Indeed, recent discoveries show that the normal overnight downscaling of slow wave activity (SWA) from the first to the last hours of sleep is absent in electrical status epilepticus during sleep (ESES) patients, thus impairing the neural process and possibly the local plastic changes associated with learning and other cognitive functions. Moreover, specific patterns of spike-induced activation (especially in perisylvian and/or prefrontal areas) and deactivation of default mode network (DMN) have been shown in patients with CSWS. Consequently, to date, we may conceive that the possible mechanisms underlying neuropsychological disorders in encephalopathic epilepsy (EE) may be double, since NREM sleep interictal epileptic discharges (IEDs) induce both a pathologic activation in epileptogenic areas and a pathologic deactivation of DMN beyond the epileptogenic zone. The growing body of literature on the effects of ESES in CSWS provides us with increasing knowledge on the complexity of brain development and a better understanding of plasticity, enlightening the pathogenesis of damage on developing neuropsychological functions. Finally, the need for an individually tailored interpretation of the neuropsychological

    2014-02-01

    This virtual issue consists of studies previously published in the Journal of the International Neuropsychological Society and selected on the basis of their content related to one of the most highly researched concepts in behavioral neurology and neuropsychology over the past decade: mild cognitive impairment (MCI). The reliance on cognitive screening measures, staging-based rating scales, and limited neuropsychological testing in diagnosing MCI across most research studies may miss individuals with subtle cognitive declines or mis-diagnose MCI in those who are otherwise cognitively normal on a broader neuropsychological battery of tests. The assembled articles highlight the perils of relying on these conventional criteria for MCI diagnosis and reveal how the reliability of diagnosis is improved when sound neuropsychological approaches are adopted. When these requirements are met, we illustrate with a second series of articles that neuropsychological measures associate strongly with biomarkers and often reflect pathology beyond or instead of typical AD distributions. The final set of articles reveal that people with MCI demonstrate mild but identifiable functional difficulties, and a challenge for neuropsychology is how to incorporate this information to better define MCI and distinguish it from early dementia. Neuropsychology is uniquely positioned to improve upon the state of the science in MCI research and practice by providing critically important empirical information on the specific cognitive domains affected by the predominant neurodegenerative disorders of late life as well as on the diagnostic decision-making strategies used in studies. When such efforts to more comprehensively assess neuropsychological functions are undertaken, better characterizations of spared and impaired cognitive and functional abilities result and lead to more convincing associations with other biomarkers as well as to prediction of clinical outcomes.

    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.

    There is widespread concern regarding the safety of silver-mercury amalgam dental restorations, yet little evidence to support their harm or safety. We examined whether mercury dental amalgams are adversely associated with cognitive functioning in a cross-sectional sample of healthy working adults. We studied 550 adults, 30-49 years of age, who were not occupationally exposed to mercury. Participants were representative of employees at a major urban medical center. Each participant underwent a neuropsychologic test battery, a structured questionnaire, a modified dental examination, and collection of blood and urine samples. Mercury exposure was assessed using a) urinary mercury concentration (UHg); b) the total number of amalgam surfaces; and c) the number of occlusal amalgam surfaces. Linear regression analysis was used to estimate associations between each marker of mercury exposure and each neuropsychologic test, adjusting for potential confounding variables. Exposure levels were relatively low. The mean UHg was 1.7 micro g/g creatinine (range, 0.09-17.8); the mean total number of amalgam surfaces was 10.6 (range, 0-46) and the mean number of occlusal amalgam surfaces was 6.1 (range, 0-19). No measure of exposure was significantly associated with the scores on any neuropsychologic test in analyses that adjusted for the sampling design and other covariates. In a sample of healthy working adults, mercury exposure derived from dental amalgam restorations was not associated with any detectable deficits in cognitive or fine motor functioning.

    ICD-10 and DSM-IV differ in their definitions of delirium. The DSM-IV definition centers around a disorder of attention and cognitive functions, whereas ICD-10 describes delirium as a broader neuropsychological and psychopathological syndrome, e.g. hallucinations, emotional and psychomotor disorder.

    2018-01-01

    Guides to neuropsychological assessment emphasize the importance of establishing rapport; however, there has been a minimal amount of empirical investigation of the impact of rapport on neuropsychological test performance. In this experiment, participants (N = 98) were randomly assigned to take neuropsychological tests in either a high or low rapport condition. Results showed that we were able to manipulate the level of rapport and that the level of rapport had a significant effect on the Grooved Pegboard Test and the Controlled Oral Word Association Test, with other tests nearing statistical significance. These results suggest that the level of rapport may affect neuropsychological test performance.

    2000-01-01

    Results from a retrospective chart review of thirty-seven patients completing an individualized cognitive rehabilitation therapy (CRT) program, using a Developmental Metacognitive approach, are reported. Neuropsychological functioning was used as the measure of progress in CRT. Demographic data, number of CRT sessions, and number of months post-injury were used to predict overall improvement in neuropsychological status. Eighty-nine percent of the patients in the CRT program experienced significant change on at least one neuropsychological measure administered. Despite considerable sample diversity, demographic and treatment variables were not predictive of overall neuropsychological change. Individualizing the CRT approach can maximize the chance of improvement in a diverse patient sample.

    Olfactory identification impairment in amnestic mild cognitive impairment (aMCI) patients is well documented and considered to be caused by underlying Alzheimer's disease (AD) pathology, contrasting with less clear evidence in non-amnestic MCI (naMCI). The aim was to (a) compare the degree of olfactory identification dysfunction in aMCI, naMCI, controls and mild AD dementia and (b) assess the relation between olfactory identification and cognitive performance in aMCI compared to naMCI. 75 patients with aMCI and 32 with naMCI, 26 patients with mild AD and 27 controls underwent the multiple choice olfactory identification Motol Hospital Smell Test with 18 different odors together with a comprehensive neuropsychological examination. Controlling for age and gender, patients with aMCI and naMCI did not differ significantly in olfactory identification and both performed significantly worse than controls (pmemory and visuospatial tests were significantly related to better olfactory identification ability. Conversely, no cognitive measure was significantly related to olfactory performance in naMCI. Olfactory identification is similarly impaired in aMCI and naMCI. Olfactory impairment is proportional to cognitive impairment in aMCI but not in naMCI. Copyright © 2015. Published by Elsevier B.V.

    The aim of this study was to investigate the comprehension of concrete, abstract and abstract emotional words in semantic variant primary progressive aphasia (svPPA), Alzheimer's disease (AD), and healthy elderly adults (HE) Three groups of participants (9 svPPA, 12 AD, 11 HE) underwent a general neuropsychological assessment, a similarity judgment task, and structural brain MRI. The three types of words were processed similarly in the group of AD participants. In contrast, patients in the svPPA group were significantly more impaired at processing concrete words than abstract words, while comprehension of abstract emotional words was in between. VBM analyses showed that comprehension of concrete words relative to abstract words was significantly correlated with atrophy in the left anterior temporal lobe. These results support the view that concrete words are disproportionately impaired in svPPA, and that concrete and abstract words may rely upon partly dissociable brain regions.

    The study aimed to highlight the importance of interdisciplinary collaboration and the value for combining normative neuropsychological and neuroradiological measures for clinical purposes. We present the case of "CL," a 65-year-old, right-handed, Caucasian female referred for a neuropsychological evaluation of memory difficulties and depression with the rule-out of pseudodementia. A brain magnetic resonance imaging (MRI) scan was conducted within 24 hours of the neuropsychology exam. Mood measures showed elevated depression and apathy symptoms. The neuropsychological profile showed variable effort, intact comprehension but compromised confrontation naming and verbal memory deficits. Using normative references from 20 female age- and education-matched healthy control peers, CL showed significantly reduced temporal cortex thickness with reduced bilateral hippocampal, right amygdala, and right caudate volumes. Combined data were supportive of a diagnosis of semantic dementia. Examining neuropsychological profiles in combination with neuroimaging standardized metrics relative to peers improved case conceptualization. Standard measures of effort and malingering examined alone and without MRI for the diagnosis of pseudodementia have questionable validity and rationale. We additionally discuss the advantages and limitations/challenges for integrating neuropsychological assessments with normative based MRI brain metrics.

    2012-01-01

    Neuropsychological assessments are increasingly in demand for a wide range of patients. This paper offers a survey of the basic aspects of neuropsychological assessment that are of greatest importance for professionals (e.g., psychologists, psychiatrists, social workers, and lawyers) who are not trained in neuropsychological testing, but who refer clients for neuropsychological assessment. This survey could also serve neuropsychologists in their early stages of training, by addressing some of the major issues related to the assessment process. The range of goals that neuropsychological assessment may attain is first outlined. Next, a model is presented that explains the rationale enabling generalization from assessment to real-world functions that are the focus of interest and the target of prediction. Issues that need to be considered before deciding to conduct a neuropsychological evaluation are then introduced, and sources of information available to the assessor are described. A description is provided of what a neuropsychological assessment includes, with an emphasis on its cognitive aspects. Finally, mention is made of some of the difficulties and challenges that must be confronted in the course of a neuropsychological assessment.

    Because little data are available on the neuropsychological functioning of severely and persistently mentally ill (SPMI) persons who are homeless, our primary goal was to describe accurately and extensively the general neuropsychological functioning of a large group of such homeless individuals. In addition, we have sought to examine the relationship between some neuropsychological functions and demographic, illness, and clinical state measures in this population. A 5-hour neuropsychological test battery was administered to 116 SPMI homeless individuals. Neuropsychological, diagnostic, substance abuse, clinical, and psychopathology data were obtained in a standardized manner. SPMI homeless individuals were significantly impaired on a wide range of neuropsychological functions. Specific test performances were most significantly related to precursor variables (level of education and parental socioeconomic status) and state variables (level of psychosis and anticholinergic medication dose). Gender and substance abuse had significant effects limited to sustained attention. Neuropsychological performance was impaired in this sample of homeless SPMI persons. Further research, using profile analysis to directly compare groups composed of homeless persons without psychiatric illness or demographically matched persons of comparable psychiatric status who are not homeless will help clarify the role of homelessness and psychosis on neuropsychological function.

    Mixed dementia (MD), i.e., the coexistence of Alzheimer's disease (AD) and cerebrovascular disease (CVD), is a common dementia subtype. Few studies have attempted to establish the cognitive profiles of mild-moderate MD and compare it to the profiles of AD using a comprehensive neuropsychological test battery. We aimed to establish the neuropsychological profile of mild-moderate MD in relation to mild-moderate AD. Patients with consensus diagnoses of MD and AD of mild-moderate severity (Clinical Dementia Rating score of 1-2) were recruited from a memory clinic. Cognitive performance was measured by a formal neuropsychological battery covering domains of attention, language, verbal and visual memory, visuoconstruction, visuomotor speed and executive function. Cognitive domain scores are z-scores calculated using the mean and SDs of the AD group. ANCOVAs with age and education as covariates were employed to examine differences in mean score difference of cognitive domains and subtests between patients with MD and AD. 151 patients were recruited with the majority of AD (n=96, 63.6%) and a minority of MD (n=55, 36.4%). There were no significant differences in the demographic characteristics of patients with MD and AD. However, patients with MD were significantly more impaired than AD patients in global cognitive composite, attention and visuoconstruction (global cognitive composite: -0.32±0.98 vs 0±1, p=0.011; attention: -0.32±0.90 vs 0±1, p=0.013; visuoconstruction: -0.27±0.99 vs 0±1, p=0.024, respectively). The neuropsychological profile of patients with MD of mild-moderate severity is characterized by a poorer global performance, as well as attention and visuoconstruction than those with AD of mild-moderate severity. © 2013 Elsevier B.V.

    Previous studies investigating neuropsychological functioning of children with autism spectrum disorder (ASD) have only analysed certain abilities, such as executive functions or language. While comprehensive assessment of the neuropsychological profile of children with ASD has been the focus of recent research, most of the published evidence originates from single centres. Though studies on differences in neuropsychological features of children with ASD across countries are essential for identifying different phenotypes of ASD, such studies have not been conducted. Our goal was to assess the neuropsychological abilities of children with ASD in northern Finland and Egypt and to examine the effect of age and intelligence quotient (IQ) on these abilities. Selected verbal and non-verbal subtests of the neuropsychological assessment NEPSY were used to examine 88 children with ASD in northern Finland (n=54, age M=11.2, IQ M=117.1) and Egypt (n=34, age M=8.4, IQ M=96.6). Finnish ASD children scored significantly higher than their Egyptian counterparts on the verbal NEPSY subtests Comprehension of Instructions (pneuropsychological performance. Our results suggest a possible cultural impact on verbal and visuomotor fluency. However, the ability to recognize and memorize objects and the disability to remember faces appear to be typical for ASD and culturally independent.

  5. History of Neuropsychology Through Epilepsy Eyes

    Loring, David W.

    2010-01-01

    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.

    The authors compared patients who underwent stereotactic subcaudate tractotomy for depression, who were still depressed or recovered from depression, to identify therapeutic mechanisms. Ten depressed and eight recovered psychosurgery patients, along with nine never-depressed subjects and nine who had recovered from depression with medication, completed the Iowa Gambling Task, a measure of decision making in the face of feedback. Psychosurgery patients also completed general neuropsychological testing. Recovered psychosurgery patients exhibited insensitivity to negative feedback on the Iowa Gambling Task compared to the other three groups. This difference between the groups remained when general neuropsychological performance was covaried out. These findings suggest acquired relative insensitivity to negative information as a specific mechanism mediating the antidepressant effect of stereotactic subcaudate tractotomy. Such insensitivity is not secondary to deficits in general neuropsychological functioning and is not a function of recovery from depression per se.

    Full Text Available Background: Previous studies investigating neuropsychological functioning of children with autism spectrum disorder (ASD have only analysed certain abilities, such as executive functions or language. While comprehensive assessment of the neuropsychological profile of children with ASD has been the focus of recent research, most of the published evidence originates from single centres. Though studies on differences in neuropsychological features of children with ASD across countries are essential for identifying different phenotypes of ASD, such studies have not been conducted. Objective: Our goal was to assess the neuropsychological abilities of children with ASD in northern Finland and Egypt and to examine the effect of age and intelligence quotient (IQ on these abilities. Design: Selected verbal and non-verbal subtests of the neuropsychological assessment NEPSY were used to examine 88 children with ASD in northern Finland (n=54, age M=11.2, IQ M=117.1 and Egypt (n=34, age M=8.4, IQ M=96.6. Results: Finnish ASD children scored significantly higher than their Egyptian counterparts on the verbal NEPSY subtests Comprehension of Instructions (p<0.001, Comprehension of Sentence Structure (p<0.01, Narrative Memory (p<0.001 and Verbal Fluency (p<0.05 and on the non-verbal NEPSY subtest Design Fluency (p<0.01. Finnish and Egyptian ASD children did not differ on the subtests Memory for Faces, Object Recognition and Object Memory. In addition, we found that age and verbal IQ can have significant influence on neuropsychological performance. Conclusions: Our results suggest a possible cultural impact on verbal and visuomotor fluency. However, the ability to recognize and memorize objects and the disability to remember faces appear to be typical for ASD and culturally independent.

    Identifying which neuropsychological measures detect early cognitive changes associated with Alzheimer disease (AD), brain pathology would be helpful clinically for the diagnosis of early AD and for the design of clinical trials. We evaluated which neuropsychological measures in our cognitive battery are most strongly associated with cerebrospinal fluid (CSF) biomarkers of AD brain pathology. We studied a large cohort (n = 233) of middle-to older-aged community-dwelling individuals (mean age 61 years) who had no clinical symptoms of dementia and underwent baseline CSF collection at baseline. Participants completed a battery of 9 neuropsychological measures at baseline and then every 1 to 3 years. CSF tau/Aβ42 was associated with baseline performance on 5/9 neuropsychological measures, especially measures of episodic memory, and longitudinal performance on 7/9 neuropsychological measures, especially measures of global cognition. The free recall portion of the Free and Cued Selective Reminding Task (FCSRT-free) detected declining cognition in the high CSF tau/Aβ42 group the earliest, followed by another measure of episodic memory and a sequencing task.

    Full Text Available Pigmented villonodular synovitis (PVNS is a rare, benign, but a locally aggressive tumor. It is characterized by the proliferation of synovial membrane, but it can also be seen in tendon sheaths and bursae. Clinical presentation of solitary lesions include compression and locking of the joint suggesting loose bodies in the joint and a subsequent findings of an effusion, whereas diffuse lesions manifest with pain and chronic swelling. In this article, we presented a curious case of PVNS in a female patient who have been followed up due to an acetabular cystic lesion. She underwent total hip arthroplasty for severe osteoarthritis of the hip joint and associated pain. The diagnosis of PVNS was established intraoperatively.

    Fletcher, Jack M; Grigorenko, Elena L

    2017-10-01

    Over the past 50 years, research on children and adults with learning disabilities has seen significant advances. Neuropsychological research historically focused on the administration of tests sensitive to brain dysfunction to identify putative neural mechanisms underlying learning disabilities that would serve as the basis for treatment. Led by research on classifying and identifying learning disabilities, four pivotal changes in research paradigms have produced a contemporary scientific, interdisciplinary, and international understanding of these disabilities. These changes are (1) the emergence of cognitive science, (2) the development of quantitative and molecular genetics, (3) the advent of noninvasive structural and functional neuroimaging, and (4) experimental trials of interventions focused on improving academic skills and addressing comorbid conditions. Implications for practice indicate a need to move neuropsychological assessment away from a primary focus on systematic, comprehensive assessment of cognitive skills toward more targeted performance-based assessments of academic achievement, comorbid conditions, and intervention response that lead directly to evidence-based treatment plans. Future research will continue to cross disciplinary boundaries to address questions regarding the interaction of neurobiological and contextual variables, the importance of individual differences in treatment response, and an expanded research base on (a) the most severe cases, (b) older people with LDs, and (c) domains of math problem solving, reading comprehension, and written expression.

    Full Text Available ABSTRACT Work can be an important etiologic factor in the genesis of some mental disorders including cognitive disability. Occupational neuropsychology constitutes an intriguing new but neglected area of research and clinical practice which deals with the neurocognitive consequences of the work environment and work habits. Neuropsychological knowledge is fundamental to understand cognitive requirements of work competence. Work can impact sleep patterns and mental energy, which in turn can cause neuropsychological symptoms. This report presents relevant evidence to illustrate the relationship between work and cognitive dysfunction.

    Neuropsychological tests and self-report personality inventories were administered to 14 workers and rescue squad personnel approximately 2 months following mild exposure to pentaborane, a highly toxic volatile liquid boron hydride. Performance decrements were evident on 5 of 11 neuropsychological tests, including Block Design and measures of sustained attention and recent memory. Neuropsychological deficits were not related to emotional changes reported on the Hopkins Symptom Checklist nor to the presence of CT scan abnormality. These results indicate mild residual brain dysfunction following pentaborane intoxication, including possible dysfunction in subcortical regions mediating memory processes and in cortical areas mediating visuo-spatial abilities

  1. Providing effective supervision in clinical neuropsychology.

    2010-01-01

    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.

    2016-11-01

    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.

    The purpose of this study was to analyze characteristics of individuals working in the profession of neuropsychology in Latin America in order to understand their background, professional training, current work situation, assessment and diagnostic procedures used, rehabilitation techniques employed, population targeted, teaching responsibilities, and research activities. A total of 808 professionals working in neuropsychology from 17 countries in Latin America completed an online survey between July 2013 and January 2014. The majority of participants were female and the mean age was 36.76 years (range 21-74 years). The majority of professionals working in neuropsychology in Latin America have a background in psychology, with some additional specialized training and supervised clinical practice. Over half work in private practice, universities, or private clinics and are quite satisfied with their work. Those who identify themselves as clinicians primarily work with individuals with learning problems, ADHD, mental retardation, TBI, dementia, and stroke. The majority respondents cite the top barrier in the use of neuropsychological instruments to be the lack of normative data for their countries. The top perceived barriers to the field include: lack of academic training programs, lack of clinical training opportunities, lack of willingness to collaborate between professionals, and lack of access to neuropsychological instruments. There is a need in Latin America to increase regulation, improve graduate curriculums, enhance existing clinical training, develop professional certification programs, validate existing neuropsychological tests, and create new, culturally-relevant instruments.

    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.

    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.

    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.

    Conversion disorder is characterized by functional impairment in motor, sensory, or neurovegetative systems that cannot be explained by a general medical condition. Diagnostic systems emphasize the absence of an organic basis for the dysfunction observed in conversion disorder. Nevertheless, there is a growing body of data on the specific functional brain correlates of conversion symptoms, particularly those obtained via neuroimaging and neurophysiological assessment. The present study aimed to determine if there are differences in measures of cognitive functioning between patients with conversion disorder and healthy controls. The hypothesis of the study was that the patients with conversion disorder would have poorer neurocognitive performance than the controls. The patient group included 43 patients diagnosed as conversion disorder and other psychiatric comorbidities according to DSM-IV-TR. Control group 1 included 44 patients diagnosed with similar psychiatric comorbidities, but not conversion diosorder, and control group 2 included 43 healthy individuals. All participants completed a sociodemographic questionnaire and were administered the SCID-I and a neuropsychological test battery of 6 tests, including the Serial Digit Learning Test (SDLT), Auditory Verbal Learning Test (AVLT), Wechsler Memory Scale, Stroop Color Word Interference Test, Benton Judgment of Line Orientation Test (BJLOT), and Cancellation Test. The patient group had significantly poorer performance on the SDLT, AVLT, Stroop Color Word Interference Test, and BJLOT than both control groups. The present findings highlight the differences between the groups in learning and memory, executive and visuospatial functions, and attention, which seemed to be specific to conversion disorder.

    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.

    Of children with neurofibromatosis (NF), 40% have a cognitive or learning impairment. Approximately 60% also have anomalous areas of high signal intensity on T2-weighted brain MRIs. The association of these hyperintensities and neuropsychological status is not fully understood. We administered a battery of neuropsychological tests and a standard clinical MRI to determine the impact of hyperintensity presence, number, and location on cognitive status in 84 children (8 to 16 years) with NF type 1. These children underwent standard clinical MRI using a GE 1.5-tesla scanner (except one child who was examined with a 1.0-tesla scanner). We conducted three types of analyses: Hyperintensity presence or absence.-Scores of children with (55%) and without hyperintensities (45%) were compared using t tests. No statistically significant differences between groups in intellectual functioning or any neuropsychological variable were found. Number of hyperintensities-The number of hyperintensity locations per child ranged from one to five (mean = 2.22). Pearson correlations revealed no significant association between the number of hyperintensities and neuropsychological performance. Location of hyperintensities-In four of the five locations studied, no statistically significant differences were found between scores of children with a hyperintensity in an area and those with one elsewhere. However, mean scores for IQ, Memory, Motor, Distractibility, and Attention domains for children with hyperintensities in the thalamus were significantly lower than scores for those with hyperintensities elsewhere. These results suggest that the simple presence or absence of hyperintensities, or their total number, is not as important as their anatomic location for detecting their relationship with neuropsychological status. Taking location into account, hyperintensities in the cerebral hemispheres, basal ganglia, brainstem, or cerebellum seem to have no impact on neuropsychological functioning

    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.

    The neuropsychological aspects of multiple sclerosis (MS) have evolved over the past three decades. What was once thought to be a rare occurrence, cognitive dysfunction is now viewed as one of the most disabling symptoms of the disease, with devastating effects on patients' quality of life. This selective review will highlight major innovations and scientific discoveries in the areas of neuropathology, neuroimaging, diagnosis, and treatment that pertain to our understanding of the neuropsychological aspects of MS. Specifically, we focus on the recent discovery that MS produces pathogical lesions of gray matter (GM) that have consequences for cognitive functions. Methods for imaging these GM lesions in MS are discussed along with multimodal imaging studies that integrate structural and functional imaging methods to provide a better understanding of the relationship between cognitive test performance and functional reserve. Innovations in the screening and comprehensive assessment of cognitive disorders are presented along with recent research that examines cognitive dysfunction in pediatric MS. Results of innovative outcome studies in cognitive rehabilitation are discussed. Finally, we highlight trends for potential future innovations over the next decade. (JINS, 2017, 23, 832-842).

    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.

    Full Text Available This study aims to explore the potential impairment of Theory of Mind (ToM (i.e., the ability to represent cognitive and affective mental states to both self and others and the clinical, neuropsychological and Quality of Life (QoL correlates of these cognitive abnormalities in the early stages of amyotrophic lateral sclerosis (ALS, a multisystem neurodegenerative disease recently recognized as a part of the same clinical and pathological spectrum of frontotemporal lobar degeneration.Twenty-two consecutive, cognitively intact ALS patients, and 15 healthy controls, underwent assessment of executive, verbal comprehension, visuospatial, behavioural and QoL measures, as well as of the ToM abilities by Emotion Attribution Task (EAT, Advanced Test of ToM (ATT and Eyes Task (ET.ALS patients obtained significantly lower scores than controls on EAT and ET. No significant difference was found between the two groups on ATT. As regard to type of ALS onset, patients with bulbar onset performed worse than those with spinal onset on ET. Correlation analysis revealed that EAT and ET were positively correlated with education, memory prose, visuo-spatial performances and Mental Health scores among QoL items.Our results suggest that not only cognitive but also affective subcomponents of ToM may be impaired in the early stages of ALS, with significant linkage to disease onset and dysfunctions of less executively demanding conditions, causing potential impact on patients' Mental Health.

    Progress in treatments has led to HIV+ patients getting older. Age and HIV are risk factors for neurocognitive impairment (NCI). We explored the role of cognitive reserve (CR) on cognition in a group of virologically suppressed older HIV+ people. We performed a multicenter study, consecutively enrolling asymptomatic HIV+ subjects ≥60 years old during routine outpatient visits. A comprehensive neuropsychological battery was administered. Raw test scores were adjusted based on Italian normative data and transformed into z-scores; NCI was defined according to Frascati criteria. All participants underwent the Brief Intelligence Test (TIB) and the Cognitive Reserve Index (CRI) questionnaire as proxies for CR. Relationships between TIB, CRI, and NCI were investigated by logistic or linear regression analyses. Sixty patients (85 % males, median age 66, median education 12, 10 % HCV co-infected, 25 % with past acquired immunodeficiency syndrome (AIDS)-defining events, median CD4 cells count 581 cells/μL, median nadir CD4 cells count 109 cells/μL) were enrolled. Twenty-four patients (40 %) showed Asymptomatic Neurocognitive Impairment. At logistic regression analysis, only CRI (OR 0.94; 95 % CI 0.91-0.97; P = 0.001) and TIB (OR 0.80; 95 % CI 0.71-0.90; P cognitive domains. Our findings highlight the role of CR over clinical variables in maintaining cognitive integrity in a virologically suppressed older HIV-infected population. A lifestyle characterized by experiences of mental stimulation may help to cope aging and HIV-related neurodegeneration.

    2010-08-01

    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.

    Neuropsychological assessment has featured prominently over the past 30 years in the characterization of dementia associated with Alzheimer disease (AD). Clinical neuropsychological methods have identified the earliest, most definitive cognitive and behavioral symptoms of illness, contributing to the identification, staging, and tracking of disease. With increasing public awareness of dementia, disease detection has moved to earlier stages of illness, at a time when deficits are both behaviorally and pathologically selective. For reasons that are not well understood, early AD pathology frequently targets large-scale neuroanatomical networks for episodic memory before other networks that subserve language, attention, executive functions, and visuospatial abilities. This chapter reviews the pathognomonic neuropsychological features of AD dementia and how these differ from “normal,” age-related cognitive decline and from other neurodegenerative diseases that cause dementia, including cortical Lewy body disease, frontotemporal lobar degeneration, and cerebrovascular disease.

    An adequate neuropsychological evaluation is essential today to obtain a correct diagnosis in most neurological and geriatric areas. For these purposes, a number of screening and evaluation tools are in use to aid the neuropsychologist for diagnosis of cognitive disorder and for assessing the type of the disease. The present research compares two neuropsychological tools, commonly used in the daily practice: the "Mini Mental State Examination" and the "Brief Neuropsychological Examination". This study explores the neuropsychological profile of 56 post-stroke patients in rehabilitation phase. Patients were divided in three groups, in order to the stroke brain area: left, right and multinfarctual. No significant difference in the three pathological groups were observed, in the mean MMSE-score. On the opposite, ENB demonstrated higher sensitivity and specificity in discrimination between pathological groups, but only on the descriptive level: for example, right-stroke patients performed worse in visuo-spatial tests while left-stroke patients had lower performance in verbal memory tests. Our results showed an inadequacy of neuropsychological screening evaluation in post-stroke patients: both Mini Mental State Examination and the Brief Neuropsychological Examination appear to be inadequate to underline specific cognitive deficits in patients with different brain lesions; therefore it is important to consider the tools adequacy and the time-after-stroke when doing neuropsychological evaluation.

  19. Pb Neurotoxicity: Neuropsychological Effects of Lead Toxicity

    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.

    Errors in communication are a leading cause of medical errors. A potential source of error in communicating neuropsychological results is confusion in the qualitative descriptors used to describe standardized neuropsychological data. This study sought to evaluate the extent to which medical consumers of neuropsychological assessments believed that results/findings were not clearly communicated. In addition, preference data for a variety of qualitative descriptors commonly used to communicate normative neuropsychological test scores were obtained. Preference data were obtained for five qualitative descriptor systems as part of a larger 36-item internet-based survey of physician satisfaction with neuropsychological services. A new qualitative descriptor system termed the Simplified Qualitative Classification System (Q-Simple) was proposed to reduce the potential for communication errors using seven terms: very superior, superior, high average, average, low average, borderline, and abnormal/impaired. A non-random convenience sample of 605 clinicians identified from four United States academic medical centers from January 1, 2015 through January 7, 2016 were invited to participate. A total of 182 surveys were completed. A minority of clinicians (12.5%) indicated that neuropsychological study results were not clearly communicated. When communicating neuropsychological standardized scores, the two most preferred qualitative descriptor systems were by Heaton and colleagues (26%) and a newly proposed Q-simple system (22%).

    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.

  6. Neuropsychological improvement in patients with cervical spondylotic myelopathy after posterior decompression surgery

    Patients with cervical spondylotic myelopathy sometimes complain of cognitive dysfunction, which may be coincidence. However, cognitive dysfunction may be related to disorders of the cervical spine and/or spinal cord. This study investigated cognitive dysfunction in patients with cervical spinal disorders. A total of 79 patients with cervical spondylotic myelopathy (40 women and 39 men, mean age 61.2 years) underwent cervical laminoplasty between January 2006 and July 2007. Ten of these 79 patients (7 women and 3 men, mean age 65.2 years) complained of moderate to severe memory disturbances. These 10 patients underwent neuroimaging studies and a battery of neuropsychological tests consisting of the mini-mental state examination, Kohs Block Design Test, Miyake Memory Test, Benton Visual Retention Test (BVRT), and 'kana-hiroi' test before and 3 months after surgery. Brain magnetic resonance imaging showed no organic brain lesions in the 10 patients, but single photon emission computed tomography demonstrated reduced regional cerebral blood flow in the posterior cortical areas in eight patients before surgery. Neuropsychological test scores showed statistically significant improvement after surgery in the Kohs Block Design Test and the BVRT, which measure visuospatial perception and reflect the function of the parietal and/or occipital lobes (p<0.05). The practice effect may have contributed to the neuropsychological improvements, but this study suggests that cervical spinal disorders may affect cognitive functions and that surgical treatment can ameliorate such effects.

    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. PMID:22766012

    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

    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.

    Inorganic arsenic at high and prolonged doses is highly neurotoxic. Few studies have evaluated whether long-term, low-level arsenic exposure is associated with neuropsychological functioning in adults. To investigate the association between long-term, low-level inorganic arsenic exposure and neuropsychological functioning among American Indians aged 64-95. We assessed 928 participants in the Strong Heart Study by using data on arsenic species in urine samples collected at baseline (1989-1991) and results of standardized tests of global cognition, executive functioning, verbal learning and memory, fine motor functioning, and speed of mental processing administered during comprehensive follow-up evaluations in 2009-2013. We calculated the difference in neuropsychological functioning for a 10% increase in urinary arsenic with adjustment for sex, age, education, and study site. The sum of inorganic and methylated arsenic species (∑As) in urine was associated with limited fine motor functioning and processing speed. A 10% increase in ∑As was associated with a .10 (95% CI -.20, -.01) decrease on the Finger Tapping Test for the dominant hand and a .13 decrease (95% CI -.21, -.04) for the non-dominant hand. Similarly, a 10% increase in ∑As was associated with a .15 (95% CI -.29, .00) decrease on the Wechsler Adult Intelligence Scale-Fourth Edition Coding Subtest. ∑As was not associated with other neuropsychological functions. Findings indicate an adverse association between increased urinary arsenic fine motor functioning and processing speed, but not with other neuropsychological functioning, among elderly American Indians.

    Increased evidence of subnormal neuropsychological functioning in new-onset childhood epilepsy has been obtained, although results are still rare and controversial. With a prospective study, we aimed to define the very early neuropsychological profile of children with benign epilepsy with centrotemporal spikes (BECTS), including executive functions (EF) because of their key role in learning. Additionally, we enrolled drug-naïve children, with a NREM sleep frequency of discharges Performance Intelligence Quotient equal or superior to 85, in order to exclude additional effects on the neuropsychological functioning. Fifteen school-aged children with BECTS (mean age: 8.8years, standard deviation [SD]: 2.4years) and fifteen healthy children (mean age: 9.2years, [SD]: 2.5years) were enrolled and assessed with a comprehensive neuropsychological battery. The assessment included domain-specific standardized tests of language, EF, academic skills, visuomotor and visuospatial skills, and short-term memory. A p-valueacademic skills, significant differences between groups emerged regarding the number of mistakes in nonword writing (p=.001), nonword reading speed (p=.027), nonword reading number of mistakes (p=.019), and word reading errors (p=.023). Results showed that children with new-onset BECTS may demonstrate a range of neuropsychological dysfunctions, particularly affecting executive attention, despite a normal IQ, a low frequency of NREM sleep discharges, and the absence of drugs. These difficulties indicate a frontal dysfunction with cascading effects on language and academic skills. The inclusion of EF in the assessment battery and in the intervention since the very onset is warranted in order to avoid further and persistent academic difficulties. Copyright © 2015 Elsevier Inc.

    2009-01-01

    As part of a special issue of The Journal of Head Trauma Rehabilitation, forensic neuropsychology is reviewed as it applies to traumatic brain injury (TBI) and other types of acquired brain injury in which clinical neuropsychologists and rehabilitation psychologists may be asked to render professional opinions about the neurobehavioral effects and outcome of a brain injury. The article introduces and overviews the topic focusing on the process of forensic neuropsychological consultation and practice as it applies to patients with TBI or other types of acquired brain injury. The emphasis is on the application of scientist-practitioner standards as they apply to legal questions about the status of a TBI patient and how best that may be achieved. This article introduces each topic area covered in this special edition.

    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.

    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.

    Postirradiation somnolence syndrome in children with acute lymphocytic leukemia treated with cranial irradiation has been identified as a possible precursor of later cognitive dysfunction. To test this, the neuropsychological evaluation of 48 children who developed somnolence syndrome was compared with that of 31 children who did not have the syndrome at approximately 1 1/2 and 3 3/4 years after treatment. No differences in performance between the two groups were found on many measures of neuropsychological functioning with the exception of fine motor speed. Children without somnolence syndrome scored somewhat less than normal on measures of academic achievement. No other differences from normal performance were noted in either group. The results of the study indicated that if children with somnolence are at greater risk for the development of cognitive dysfunction than those not manifesting the syndrome, such risks occur at a time farther from treatment than 3 to 4 years

  6. Behavior, neuropsychology and fMRI.

    Science.gov (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.

    Cukier, Sebastián H

    2005-01-01

    Autism constitutes one of the most investigated disorders in child psychiatry. The heterogeneous clinical phenomena that characterize it have been exhaustibly described along the last 62 years. Multiple aetiological hypothesis, neuropsychological theories and physiopathological mechanisms, sometimes complementary and other times mutually exclusive, and different descriptions of neurobiological alterations that resulted, in general, of low replicability, have attempted to account for the marked variability of its manifestations. An integration of these different levels of analysis results even harder than the comprehension of each of them separately. In this article the author revises the three aspects considered the most characteristic of the syndrome (social interaction, communication and flexibility) and tries to integrate its clinical manifestations with some neuropsychological variables and the neurobiological substrates.

    This theoretical paper reviews an emerging literature which attempts to bring together an important area of social psychology and neuropsychology. The paper presents a rationale for the integration of the social identity and clinical neuropsychological approaches in the study of acquired brain injury (ABI). The paper begins by reviewing the social and neuropsychological perspectives of ABI. Subsequently, theoretical and empirical studies that demonstrate the social influences on neuropsychology and the inherently social nature of mind are considered. Neuropsychological understandings of social identities and their potential relationships to the variability in ABIs are also discussed. The values of these understandings to ABI rehabilitation are then examined. The paper concludes by suggesting an agenda for future research that integrates the social identity and neuropsychological paradigms so that psychology might grow in its store of applicable knowledge to enhance support and rehabilitation for those with ABI.

    To describe the history, current situation, and future challenges of Argentinian neuropsychology. A brief historical description highlighting the most representative authors and publications is made. In addition, a survey was administered to a sample of 135 neuropsychologists practicing neuropsychology in Argentina. The survey explored the current neuropsychological practices among the respondents. Results show that most Argentinian neuropsychologists are: psychologists, women, and work in the clinical field in the country's major cities. Besides, the practice of neuropsychology is mostly unregulated with few training opportunities. Argentinian neuropsychology emerged from neurology in the early twentieth century and slowly progressed until the 1960s when the first organized research groups were created. Since then, a substantial and steady progress followed. However, more training opportunities and a better regulation of the discipline are needed. No similar studies have been conducted in the past, thus becoming one of the first to describe the development of neuropsychology in Argentina.

    Gambling is a form of nonsubstance addiction classified as an impulse control disorder. Pathologic gamblers are considered healthy with respect to their cognitive status. Lesions of the frontolimbic systems, mostly of the right hemisphere, are associated with addictive behavior. Because gamblers are not regarded as "brain-lesioned" and gambling is nontoxic, gambling is a model to test whether addicted "healthy" people are relatively impaired in frontolimbic neuropsychological functions. Twenty-one nonsubstance dependent gamblers and nineteen healthy subjects underwent a behavioral neurologic interview centered on incidence, origin, and symptoms of possible brain damage, a neuropsychological examination, and an electroencephalogram. Seventeen gamblers (81%) had a positive medical history for brain damage (mainly traumatic head injury, pre- or perinatal complications). The gamblers, compared with the controls, were significantly more impaired in concentration, memory, and executive functions, and evidenced a higher prevalence of non-right-handedness (43%) and, non-left-hemisphere language dominance (52%). Electroencephalogram (EEG) revealed dysfunctional activity in 65% of the gamblers, compared with 26% of controls. This study shows that the "healthy" gamblers are indeed brain-damaged. Compared with a matched control population, pathologic gamblers evidenced more brain injuries, more fronto-temporo-limbic neuropsychological dysfunctions and more EEG abnormalities. The authors thus conjecture that addictive gambling may be a consequence of brain damage, especially of the frontolimbic systems, a finding that may well have medicolegal consequences.

    Few data are available on the neuropsychological, behavioural, or structural brain imaging outcomes in adolescents who underwent corrective surgery in infancy for tetralogy of Fallot. In this single-centre cross-sectional study, we enrolled 91 adolescents (13-16 years old) with tetralogy of Fallot and 87 referent subjects. Assessments included tests of academic achievement, memory, executive functions, visual-spatial skills, attention, and social cognition, as well as brain magnetic resonance imaging. Genetic abnormalities or syndromes were present in 25% of tetralogy of Fallot patients, who had markedly greater neuropsychological morbidities than did patients without a syndrome. However, even patients without a syndrome performed significantly worse than the referent group or population norms in all of the neuropsychological domains assessed. In multivariable regression in those without a genetic/phenotypic syndrome, the strongest predictors of adverse late neurodevelopmental outcomes included a greater number of complications at the first operation, more total surgical complications across all operations, and occurrence of post-operative seizures. The presence of at least one abnormality on structural magnetic resonance imaging was more frequent in tetralogy of Fallot patients than the referent group (42% versus 8%). Adolescents with tetralogy of Fallot are at increased neurodevelopmental risk and would benefit from ongoing surveillance and educational supports even after childhood.

    1994-01-01

    Full Text Available A 25 year old male patient presented with the “delusion of doubles” (Capgras syndrome. The patient underwent detailed neuropsychological, single photon emission computed tomography (SPECT and magnetic resonance imaging (MRI investigations. The neuropsychological results indicated that he was of average premorbid intelligence, which was consistent with current estimates, and had a degree of everyday memory dysfunction which was below norms derived from healthy controls, but was average relative to schizophrenic norms. He demonstrated average or above average recognition memory for patterns, spaces or words, but exhibited a marked and disproportionate impairment in face recognition, performing at the 5th percentile. In addition he demonstrated markedly impaired performance on various tests of executive function. MRI scanning revealed no focal abnormality; slight ventricular dilatation was noted. SPECT scanning, however, revealed marked right/left asymmetries of tracer uptake, restricted to occipital and calcarine cortices. These asymmetries were well outside those derived from a cohort of healthy controls. These results are discussed in relation to current neuropsychological models of Capgras syndrome.

    The purpose of this study was to verify possible cognitive dysfunction in patients with juvenile myoclonic epilepsy (JME) and its relationship to factors related to epilepsy and schooling. Fifty subjects diagnosed with JME and 50 controls underwent neuropsychological assessment evaluating intellectual functions, attention, memory, executive functions, and language. The patients were further divided into two subgroups on the basis of educational level: 11 years of formal education. Participants diagnosed with JME scored significantly below age-, education-, and gender-matched controls on neuropsychological measures of attention, immediate verbal memory, mental flexibility, control of inhibition, working memory, processing speed, verbal delayed memory, visual delayed memory, naming, and verbal fluency. A positive correlation was observed between duration of epilepsy and cognitive decline. However, in the group of patients with >11 years of education, this correlation was not significant. In this series of patients with JME, neuropsychological evaluation suggests widespread cognitive dysfunction outside the limits of the frontal lobes. The duration of epilepsy correlated with cognitive decline, and patients with higher education manifested less progression of deficits.

    Full Text Available Background. 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. Methods. 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. Results. 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. Conclusions. 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.

    Apathy is one of the most common neuropsychiatric symptoms in Parkinson's disease (PD). Few studies have investigated the cognitive and neuroanatomical correlates of apathy in PD, and those which have done so have not controlled for the presence of other neuropsychiatric comorbidities. To explore the cognitive and neuroanatomical correlates of apathy in PD at a mild disease stage. Sixty-five PD patients and 24 healthy controls participated in this study. Patients underwent extensive neuropsychological screening, neuropsychiatric assessment using the Neuropsychiatric Inventory, structural MRI scanning, and neurological examination. Voxel-based independent t-test analyses were used to assess the differences in grey and white matter volumes between the sample groups with/without apathy/neuropsychiatric symptoms. Patients with apathy had lower grey matter volume in several brain areas including the left insula, left inferior/middle/medial frontal gyrus, right anterior cingulate, and the left superior temporal gyrus. Significant impairments were found in tests assessing executive functions, and a trend-level significant difference was observed in long term memory tests in patients with apathy, when compared with patients without apathy. Apathy was associated with greater levels of atrophy in the frontal and temporal cortex, and anterior cingulate, as well as overall lower level of cognitive performance, particularly in executive function and memory skills. Apathy appears to be associated with cognitive impairments in PD, therefore, treatment of this symptom might mitigate its effects on cognitive performance in this clinical population.

    2007-01-01

    Despite an emerging literature characterizing the neuropsychological profiles of borderline, antisocial, and schizotypal personality disorders, relations between personality disorder traits and neurocognitive domains remain unknown. The authors examined associations among Millon Clinical Multiaxial Inventory-III personality disorder scales and eight neuropsychological domains in 161 patients referred for neuropsychological evaluation following closed head injury. Most personality disorder scales were associated with some decrement in cognitive function, particularly speeded processing, executive function, and language, while histrionic and narcissistic scales had positive relations with neuropsychological functioning. Results suggest that many personality disorder traits are related to neurocognitive function, particularly those functions subserved by frontal and temporal regions.

    The number of women in neuropsychology has been increasing over the past 20 years while the number of women in senior and leadership positions within neuropsychology has not. The field of neuropsychology has much to gain by facilitating the advancement of women into leadership roles, including access to some of the brightest and creative minds in the field. The purpose of this article is to offer practical advice about how to overcome barriers and advance within neuropsychology. Suggestions for professional organizations, women, and mentors of women are provided that will likely benefit trainees and junior colleagues regardless of their gender. PMID:18841516

    Neuropsychology is poised for transformations of its concepts and methods, leveraging advances in neuroimaging, the human genome project, psychometric theory, and information technologies. It is argued that a paradigm shift towards evidence-based science and practice can be enabled by innovations, including: (1) formal definition of neuropsychological concepts and tasks in cognitive ontologies; (2) creation of collaborative neuropsychological knowledgebases; and (3) design of web-based assessment methods that permit free development, large-sample implementation, and dynamic refinement of neuropsychological tests and the constructs these aim to assess. This article considers these opportunities, highlights selected obstacles, and offers suggestions for stepwise progress towards these goals. PMID:21092355

    Previous studies have found that schoolchildren with attention-deficit/hyperactivity disorder (ADHD) showed difficulties in neuropsychological function. This study aimed to assess neuropsychological function in Chinese preschoolers with ADHD using broad neuropsychological measures and rating scales and to test whether the pattern and severity of neuropsychological weakness differed among ADHD presentations in preschool children. The 226 preschoolers (163 with ADHD and 63 controls) with the age of 4-5 years were included and assessed using the Behavior Rating Scale of Executive Function-Preschool Version (BRIEF-P) and a series of tests to investigate neuropsychological function. Preschoolers with ADHD showed higher scores in all domains of the BRIEF-P (inhibition: 30.64 ± 5.78 vs.20.69 ± 3.86, P < 0.001; shift: 13.40 ± 3.03 vs.12.41 ± 2.79, P = 0.039; emotional control:15.10 ± 3.53 vs.12.20 ± 2.46, P < 0.001; working memory: 28.41 ± 4.99 vs.20.95 ± 4.60, P < 0.001; plan/organize: 17.04 ± 3.30 vs.13.29 ± 2.40, P < 0.001) and lower scores of Statue (23.18 ± 7.84 vs.28.27 ± 3.18, P = 0.001), Word Generation (15.22 ± 6.52 vs.19.53 ± 7.69, P = 0.025), Comprehension of Instructions (14.00 ± 4.44 vs.17.02 ± 3.39, P = 0.016), Visuomotor Precision (P < 0.050), Toy delay (P = 0.048), and Matrices tasks (P = 0.011), compared with normal control. In terms of the differences among ADHD subtypes, all ADHD presentations had higher scores in several domains of the BRIEF-P (P < 0.001), and the ADHD-combined symptoms (ADHD-C) group had the poorest ratings on inhibition and the ability to Plan/Organize. For neuropsychological measures, the results suggested that the ADHD-C group had poorer performances than the ADHD-predominantly inattentive symptoms (ADHD-I) group on Statue tasks (F = 7.34, η 2 = 0.12, P < 0.001). Furthermore, the ADHD-hyperactive/impulsive symptoms group had significantly poorer performances compared to the ADHD-C group in the Block Construction

    Recent evidence suggests that recreational cocaine use is on the increase, with the UK reporting one of the highest levels of use in the EU (EMCDDA 2010). Nevertheless, very few studies have addressed the neuropsychological effects associated with non-dependent recreational cocaine use. The current study aimed to assess whether recreational cocaine users show neuropsychological deficits on a battery of tests, previously shown to be sensitive to cocaine-dependent and psychosis-prone individuals. Schizotypal traits were also measured. Recreational cocaine users (n = 17) were compared with controls (n = 24) on drug use patterns, the General Health Questionnaire, the Brief Schizotypal Personality Questionnaire (SPQ-B) and four neuropsychological tasks: spatial working memory, intra/extra-dimensional set shifting, the Stocking of Cambridge and the rapid visual processing. Relative to controls, recreational cocaine users produced significantly more errors on the intra/extra-dimensional set shift task and completed fewer stages, made significantly more six box stage errors on the spatial working memory task, and made significantly more errors and fewer hits, with overall poorer detection rates on the rapid visual processing task. Recreational cocaine users reported significantly higher scores on the cognitive perceptual and disorganised thinking SPQ-B subscales and total SPQ-B scores compared to controls. Recreational cocaine users displayed impairments on tasks tapping sustained attention, attentional shifting and spatial memory and reported higher schizotypal trait expression. These findings are consistent with the emerging literature suggesting subtle cognitive deficits, putatively reflecting underlying dopaminergic dysfunction, in non-dependent, recreational cocaine users.

    In this study, we aimed to identify cognitive function and neuropsychological comorbidities in children with newly diagnosed idiopathic epilepsy. We retrospectively reviewed the records of 97 antiepileptic drug-naïve children (9.7 ± 2.9 years; 54 males and 43 females) with newly diagnosed idiopathic epilepsy, all of whom underwent a neuropsychological battery. The battery consisted of the Korean Wechsler Intelligence Scale, Attention Deficit Hyperactivity Disorder (ADHD) Rating Scale, ADHD Diagnostic System, Children's Depression Inventory, and State-Trait Anxiety Inventory for Children. We investigated association between scores of the neuropsychological battery and epilepsy classification, lateralization of interictal epileptiform discharges (IEDs) on electroencephalography (EEG), and variables related to seizures. Thirteen patients (14.3%) had ADHD symptoms. Three patients (4.1%) had depressive symptoms, and 9 (12.3%) had anxiety symptoms. Patients with idiopathic generalized epilepsy (IGE) had significantly lower full-scale intelligence and performance intelligence quotient scores than patients with idiopathic localization-related epilepsy (ILRE) (89.0 ± 17.6 vs. 96.3 ± 14.8; P = 0.030 and 88.9 ± 16.3 vs. 97.0 ± 16.4; P = 0.016, respectively). Patients with ILRE having unilateral IEDs had significantly higher full-scale intelligence quotient scores than patients with ILRE having bilateral IEDs and patients with IGE (99.9 ± 12.2 vs. 93.7 ± 16.1 vs. 89.0 ± 17.6; P = 0.039, respectively). Our results suggest that idiopathic epilepsy may be accompanied by various neuropsychological comorbidities even at initial diagnosis. Patients with IGE and ILRE having bilateral IEDs on EEG appear more likely to be at high risk of decreased cognitive function. © 2018 The Korean Academy of Medical Sciences.

    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).

    Case series methodology involves the systematic assessment of a sample of related patients, with the goal of understanding how and why they differ from one another. This method has become increasingly important in cognitive neuropsychology, which has long been identified with single-subject research. We review case series studies dealing with impaired semantic memory, reading, and language production, and draw attention to the affinity of this methodology for testing theories that are expressed as computational models and for addressing questions about neuroanatomy. It is concluded that case series methods usefully complement single-subject techniques. PMID:21714756

    The aim of this paper is to investigate the relationship between the affective and cognitive states of neurooncological patients prior to the neurosurgical treatment to assess associations between distress levels and neuropsychological test performance in this sample and setting. The prospective study population consists of 172 patients. Patients were studied preoperatively with a comprehensive test battery consisting of a variety of affective and cognitive measures. Psychological instruments included the Hospital Anxiety and Depression Scale, the Amsterdam Preoperative Anxiety and Information Scale, and the Acute Stress Disorder Scale. Factor analysis revealed two factors representing subjective affective functioning: whereas one reflects the patients' more general emotional state (Hospital Anxiety and Depression Scale, Acute Stress Disorder Scale), the second reflects anxiety specifically related to the neurosurgical procedure (Amsterdam Preoperative Anxiety and Information Scale). After age and education have been accounted for via linear regression analyses, affect did not contribute to cognitive performance in any of the cognitive domains in the whole patient sample. However, in patients with extreme levels of psychiatric morbidity, there was evidence for distinct cognitive morbidity consistent with previous research. Our results suggest that, for a large variety of widely used neuropsychological measures and for most neurooncological patients, the preoperative neuropsychological baseline assessment can be considered valid and dependable. In patients with extreme levels of distress, however, distinct cognitive domains might be differentially affected. Copyright © 2012 John Wiley & Sons, Ltd.

    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.

    We explored the prognostic value of diffusion tensor imaging (DTI) parameters of selected white matter (WM) tracts in predicting neuropsychological outcome, both at baseline and 6 months later, among well-characterized patients diagnosed with mild traumatic brain injury (mTBI). Sixty-one patients with mTBI (mean age=27.08; standard deviation [SD], 8.55) underwent scanning at an average of 10 h (SD, 4.26) post-trauma along with assessment of their neuropsychological performance at an average of 4.35 h (SD, 7.08) upon full Glasgow Coma Scale recovery. Results were then compared to 19 healthy control participants (mean age=29.05; SD, 5.84), both in the acute stage and 6 months post-trauma. DTI and neuropsychological measures between acute and chronic phases were compared, and significant differences emerged. Specifically, chronic-phase fractional anisotropy and radial diffusivity values showed significant group differences in the corona radiata, anterior limb of internal capsule, cingulum, superior longitudinal fasciculus, optic radiation, and genu of corpus callosum. Findings also demonstrated associations between DTI indices and neuropsychological outcome across two time points. Our results provide new evidence for the use of DTI as an imaging biomarker and indicator of WM damage occurring in the context of mTBI, and they underscore the dynamic nature of brain injury and possible biological basis of chronic neurocognitive alterations.

    In our study we analysed clinical and neuropsychological data in a cohort of 57 Sardinian patients with FTD (55 apparently unrelated and two belonging to the same family), who underwent genetic screening for the C9orf72 mutation. Eight out of 56 patients were found positive for the C9orf72 mutation representing 14% of the entire cohort and 31.6% of the familial cases (6/19). C9orf72 mutated patients differed from the other FTD cases of the cohort for a younger age of onset, higher frequency of familial history for FTD and higher prevalence of delusional psychotic symptoms and hallucinations. In the neuropsychological assessment, C9orf72 mutated patients differed from non-mutated for the high frequency of visuospatial dysfunction regarding constructional apraxia (p = 0.02). In conclusion, our study confirms that Sardinian FTD patients have peculiar genetic characteristics and that C9orf72 mutated patients have a distinctive clinical and neuropsychological profile that could help differentiate them from other FTD patients. In our cohort we found that constructional apraxia, rarely reported in FTD, can properly discriminate between C9orf72 mutated and non-mutated patients and contribute to broaden the neuropsychological profile in frontotemporal dementia associated with this mutation.

    In order to assess the effects of various cancer treatments on neuropsychological functioning, 74 long-term survivors of childhood cancer were examined. A comprehensive battery of tests was administered to two CNS treatment groups (irradiated and nonirradiated leukemia and lymphoma patients) and a control group (solid tumor and Hodgkin disease patients receiving no CNS treatment). The CNS-irradiated group obtained lower scores than the other two groups, with significant differences in visual-motor and fine motor skills, spatial memory, and arithmetic achievement resulting in significant differences in IQ scores (VIQ, PIQ, FSIQ). The results are discussed in relation to: (1) the effects of CNS irradiation on cognitive development; (2) the specificity of these effects; and (3) the relationship of age at diagnosis to treatment effects. It is concluded that although there is a general lowering of scores after CNS irradiation, the effect is most pronounced for nonlanguage skills. Age at diagnosis was less important than the type of treatment, with CNS irradiation reducing performance regardless of when cancer was diagnosed. There were indications that children with any type of cancer diagnosed before age 5 years are more likely to have some cognitive difficulties

  13. [Towards a neuropsychological approach to autism

    Neuropsychology attributes mental activity to brain functioning. An inventory of the every-day life of the autist confirms a breakdown in behavior adapted to the world around him. Deficiency in the contribution of the right hemisphere, compromising social life, is accompanied by a mental life that is detached from reality, favorizing preconceived ideas that are inscribed in the logic governing the left hemispheric function. Inside each hemisphere homologous areas of the cerebral cortex, receiving and sharing the same information, react to messages according to their own mode. The left hemisphere applies itself to elementary information, treated sequentially, while the right hemisphere continuously brings up to date temporal and spatial synthesis coming from the sensorale contribution. Attachment to an object or attentiveness to the world: this alternative mode is the key to understanding. The disorder responsible for autism occurs in the perinatal period. It compromizes the maturation of right hemisphere functions where interaction with the surrounding environment should take precedence over attention to objects. Besides its interest in the orientation of research, the neuropsychological approach of Pervasive Development Disorder has the merit of demystifying the drama associated with autism. A better understanding of the nature of this disorder would be of great assistance in circumventing it.

    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.

    Mindfulness based interventions (MBI) have recently gained much interest in western medicine. MBSR paradigm is based on teaching participants to pay complete attention to the present experience and act nonjudgmentally towards stressful events. During this mental practice the meditator focuses his or her attention on the sensations of the body. While the distractions (mental images, thoughts, emotional or somatic states) arise the participant is taught to acknowledge discursive thoughts and cultivate the state of awareness without immediate reaction. The effectiveness of these programs is well documented in the field of emotional response regulation in depression (relapse prevention), anxiety disorders, obsessive-compulsive disorder or eating disorders. Furthermore, converging lines of evidence support the hypothesis that mindfulness practice improves cognition, especially the ability to sustain attention and think in a more flexible manner. Nevertheless, formal rehabilitation programs targeting cognitive disturbances resulting from psychiatric (depression, disorder bipolar, schizophrenia) or neurologic conditions (brain injury, dementia) seldom rely on MBI principles. This review of literature aims at discussing possible links between MBI and clinical neuropsychology. We conducted a review of literature using electronic databases up to December 2016, screening studies with variants of the keywords ("Mindfulness", "MBI", "MBSR", "Meditation") OR/AND ("Cognition", "Attention", "Executive function", "Memory", "Learning") RESULTS: In the first part, we describe key concepts of the neuropsychology of attention in the light of Posner's model of attention control. We also underline the potential scope of different therapeutic contexts where disturbances of attention may be clinically relevant. Second, we review the efficacy of MBI in the field of cognition (thinking disturbances, attention biases, memory and executive processes impairment or low metacognitive abilities

    This special issue of The Clinical Neuropsychologist focuses on advances in the emerging subspecialty of pediatric neuropsychology. The national and international contributions in this issue cover a range of key clinical, research, training, and professional issues specific to pediatric neuropsychology. The genesis for this project developed out of a series of talks at the Philadelphia Pediatric Neuropsychology Symposium in 2010, hosted by the Stein Family Fellow, the Department of Psychology of the College of Arts and Sciences at Drexel University, and the Philadelphia Neuropsychology Society. Articles that explore clinical practice issue focus on the assessment of special medical populations with congenital and/or acquired central nervous system insults. Research articles investigate the core features of developmental conditions, the use of technology in neuropsychological research studies, and large sample size genomic, neuropsychological, and imaging studies of under-represented populations. The final series of articles examine new considerations in training, advocacy, and subspecialty board certification that have emerged in pediatric neuropsychology. This introductory article provides an overview of the articles in this special issue and concluding thoughts about the future of pediatric neuropsychology.

    HIV-associated neurocognitive disorders are frequently observed in people with HIV. We aimed to evaluate the influence of cognitive reserve on the neuropsychological performance of seropositive drug users. We carried out a neuropsychological assessment and compared the performance of seropositive drug users (n = 75) with that of a group of seronegative drug users (n = 48). The results showed that a low cognitive reserve makes the seropositive patients neuropsychologically vulnerable. Likewise, we found that a high cognitive reserve has a protective effect in the presence of neuropsychological impairment associated with HIV. In the seronegative group, differences in a small number of tests were found between participants with low and high cognitive reserve. Overall, these data suggest that seropositivity is not sufficient to explain the neuropsychological alterations of seropositive drug users; rather, these alterations are multifactorial.

    Neuropsychology's origins began long before there were any in vivo methods to image the brain. That changed with the advent of computed tomography in the 1970s and magnetic resonance imaging in the early 1980s. Now computed tomography and magnetic resonance imaging are routinely a part of neuropsychological investigations with an increasing number of sophisticated methods for image analysis. This review examines the history of neuroimaging utilization in neuropsychological investigations, highlighting the basic methods that go into image quantification and the various metrics that can be derived. Neuroimaging methods and limitations for identify what constitutes a lesion are discussed. Likewise, the influence of various demographic and developmental factors that influence quantification of brain structure are reviewed. Neuroimaging is an integral part of 21st Century neuropsychology. The importance of neuroimaging to advancing neuropsychology is emphasized.

    2010-01-01

    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 factors that underlie cognitive test score disparities. To this end, the present article considers several topics relevant to the measurement of cognitive abilities across groups from diverse ancestral origins, including fairness and bias, equivalence, diagnostic validity, item response theory, and differential item functioning.

    Full Text Available The aim of the present study was to investigate associations among symptoms of depression, anxiety, pain perception and cognitive impairment in patients with a diagnosis of fibromyalgia. We evaluated 32 women volunteers with a diagnosis of fibromyalgia based on the criteria of the ACR. The control group was matched to the patient group for age, schooling and income. The volunteers were submitted to a neuropsychological battery focused on Memory, Attention, Executive Functions, Perceived Pain, Anxiety and Depression. Anxiety was more relevant than depression in the group of women with fibromyalgia, the perception of pain was very high and cognitive impairment was more evident in executive functions, especially planning and inhibitory control. Memory and attention were more impaired in the fibromyalgia group, especially on tasks that require executive functions. Patients with fibromyalgia seem to be less efficient in tasks related to executive functions.

    Full Text Available OBJECTIVES: Endophenotypes in schizophrenia research is a contemporary approach to studying this heterogeneous mental illness, and several candidate neurophysiological markers (e.g. P50 sensory gating and neuropsychological tests (e.g. Continuous Performance Test (CPT and Wisconsin Card Sorting Test (WCST have been proposed. However, the clinical utility of a single marker appears to be limited. In the present study, we aimed to construct a diagnostic model incorporating P50 sensory gating with other neuropsychological tests in order to improve the clinical utility. METHODS: We recruited clinically stable outpatients meeting DSM-IV criteria of schizophrenia and age- and gender-matched healthy controls. Participants underwent P50 sensory gating experimental sessions and batteries of neuropsychological tests, including CPT, WCST and Wechsler Adult Intelligence Scale Third Edition (WAIS-III. RESULTS: A total of 106 schizophrenia patients and 74 healthy controls were enrolled. Compared with healthy controls, the patient group had significantly a larger S2 amplitude, and thus poorer P50 gating ratio (gating ratio = S2/S1. In addition, schizophrenia patients had a poorer performance on neuropsychological tests. We then developed a diagnostic model by using multivariable logistic regression analysis to differentiate patients from healthy controls. The final model included the following covariates: abnormal P50 gating (defined as P50 gating ratio >0.4, three subscales derived from the WAIS-III (Arithmetic, Block Design, and Performance IQ, sensitivity index from CPT and smoking status. This model had an adequate accuracy (concordant percentage = 90.4%; c-statistic = 0.904; Hosmer-Lemeshow Goodness-of-Fit Test, p = 0.64>0.05. CONCLUSION: To the best of our knowledge, this is the largest study to date using P50 sensory gating in subjects of Chinese ethnicity and the first to use P50 sensory gating along with other neuropsychological tests

    The aim of the study was to establish current scope of knowledge regarding associations between neurophysiological functioning, neuropsychology and psychoterapy. A systematic review was performed including 93 publications from Science Server, which contains the collections of Elsevier, Springer Journals, SCI-Ex/ICM, MEDLINE/PubMed, and SCOPUS. The works have been selected basing on following key words: 'neuropsychology, neurocognitive correlates, electrodermal response, event related potential, EEG, pupillography, electromiography' out of papers published between 2004-2015. Present reports on the use of neurophysiological methods in psychology can be divided into two areas: experimental research and research of the practical use of conditioning techniques and biofeedback in the treatment of somatic disease. Among the experimental research the following have been distinguished: research based on the startle reflex, physiological reaction to novelty, stress, type/amount of cognitive load and physiological correlates of emotion; research on the neurophysiological correlates of mental disorders, mostly mood and anxiety disorders, and neurocognitive correlates: of memory, attention, learning and intelligence. Among papers regarding the use of neurophysiological methods in psychology two types are the most frequent: on the mechanisms of biofeedback, related mainly to neuro- feedback, which is a quickly expanding method of various attention and mental disorders'treatment, and also research of the use of conditioning techniques in the treatment of mental disorders, especially depression and anxiety. A special place among all the above is taken by the research on electrophysiological correlates of psychotherapy, aiming to differentiate between the efficacy of various psychotherapeutic schools (the largest amount of publications regard the efficacy of cognitive-behavioral psychotherapy) in patients of different age groups and different diagnosis.

    Anosognosia is often found in Alzheimer's disease (AD), but its relationship with cognitivebehavioral changes is not well established. To verify if anosognosia is related to cognitive-behavioral disturbances, and to regional brain dysfunction as evaluated by neuroimaging. We included AD patients with Mini-Mental State Examination (MMSE) scores of 12 through 24, and Clinical Dementia Rating (CDR) scores of 1 or 2. Dementia diagnosis was based on DSM-IV and NINCDS-ADRDA criteria.We used Self-Consciousness Questionnaire (SCQ) and Denial of Illness Scale (DIS), and following neuropsychological counterproofs: WAIS-R digit span, Rey auditory verbal learning, verbal fluency test (category: animals), Cummings' neuropsychiatric inventory (NPI) and Cornell scale for depression in dementia (CSDD). We studied 21 patients (12 men, 9 women) with AD (14 mild, 7 moderate), age 72.4±8.5 years, education 4.9± 4.2 years, and MMSE score 18.2±5. SCQ and DIS did not correlate to age, education, or regional cerebral perfusion defects, but they tended to correlate to disease duration (and only SCQ also to MMSE). SCQ and DIS were correlated neither to CSDD, NPI, CDR, nor to any neuropsychological test. Significant correlations were found between SCQ and DIS, as well as between SCQ domain of "moral judgment" and MMSE. SCQ and DIS were not correlated to age, education, disease duration, cognitive-behavioral measures, dementia severity, or regional cerebral perfusion defects, but were correlated to each other, suggesting SCQ and DIS evaluate similar mental functions.

    This study assessed the association between cadmium exposure and neuropsychological development in children from a region with high industrial and mining activities in southwestern Spain. We conducted a cross-sectional study with 261 children aged 6–9 years between January and March 2012. Cadmium exposure was measured in urine and hair of children, and neuropsychological development was assessed with the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) and with three computerized tests from the Behavioral Assessment and Research System (BARS): Reaction Time Test (RTT), Continuous Performance Test (CPT) and Selective Attention Test (SAT). Multivariate linear regression models, adjusted for potential confounders, were used to estimate the association between neuropsychological development and cadmium exposure measured in urine and hair samples. Geometric means of urine and hair cadmium levels were 0.75 μg/g creatinine and 0.01 μg/g, respectively. We observed that doubling of levels of cadmium in urine was associated with a reduction of two points (95% CI: −3.8 to −0.4) in the Full-Scale intelligence quotient (IQ) in boys. By domains, association was statistically significant for Verbal Comprehension (β=−2.0; p=0.04) and close to the significance level for Perceptual Reasoning (β=−1.8; p=0.06). Among girls, only Verbal Comprehension showed suggestive associations with cadmium exposure (β=−1.7; p=0.06). Cadmium exposure is associated with cognitive delays in boys in our region. Our results provide additional evidence of the neurotoxic effect of low-level postnatal cadmium exposure among children, and support the hypothesis of differences between sexes in the neurotoxic effect of metals on children. - Highlights: • This study associates Cd exposure and neuropsychological development in children. • Cd exposure was associated with cognitive delay in boys, but not in girls. • Intellectual quotient of boys decreased two points for a

    This study assessed the association between cadmium exposure and neuropsychological development in children from a region with high industrial and mining activities in southwestern Spain. We conducted a cross-sectional study with 261 children aged 6–9 years between January and March 2012. Cadmium exposure was measured in urine and hair of children, and neuropsychological development was assessed with the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) and with three computerized tests from the Behavioral Assessment and Research System (BARS): Reaction Time Test (RTT), Continuous Performance Test (CPT) and Selective Attention Test (SAT). Multivariate linear regression models, adjusted for potential confounders, were used to estimate the association between neuropsychological development and cadmium exposure measured in urine and hair samples. Geometric means of urine and hair cadmium levels were 0.75 μg/g creatinine and 0.01 μg/g, respectively.

    Full Text Available The paper provides the results of neuropsychological examinations in 10 patients with Parkinson’s disease who underwent deep electrical stimulation of pallidar complex structures. The general neuropsychological test battery that had been developed by A.R. Luria and allowed the qualitative classification of the cognitive impairment symptoms detectable on examination to be made was used to study cognitive functions. The patients were examined before and just after surgery and in the late period (following 1—2 years. The examinations have shown that the syndromes indicative of dysfunctions in the deep, parietal, and occipital and prefrontal regions of the left hemisphere and in the parietooccipital regions of the right hemisphere are stable components that determine the pattern of cognitive disorders and are preserved throughout all examinations.

    Full Text Available Objective To assess the neuropsychological function and quality of life of the patients after awake craniotomy (AC. Methods A case-control study was conducted among 81 patients who underwent awake craniotomy, and a 1-to-1 control group (matched by age, gender, degree of education, tumor location and characteristic undergoing general anesthesia (GA in glioma resections was assembled. The incidence of postoperative neurological deficits, psychological disorders and recurrence were investigated during telephone follow-ups, and Medical Outcomes Study Short Form 36 (SF-36 was adopted to evaluate the life quality of patients. Results Almost 73 pairs of patients fulfilled the survey of AC and GA group respectively. There were 21 patients and 28 patients with postoperative neurological deficits, and 12 patients and 8 patients with psychological disorders in AC and GA group respectively. Thirty patients of AC group had the recollection of being awake during the surgery. There were 9 patients in CA group having long-term ( > 6 months neurological deficits, which was less than the number of GA group (18 patients, P = 0.038. According to the assessment in short-term, medium-term and long-term postoperative neurological deficits, there was no significant difference in the quality-of-life scores between the two groups (P > 0.05, for all. Conclusion Awake craniotomy can be the main method for removing the lesions located in or close to functional areas with lower incidence of long?term postoperative neurological deficits, and it has no significant impact on the psychological status and the quality of life postoperatively.

    To examine the long-term neuropsychological outcome of children with a prenatal diagnosis of asymmetric ventricles or unilateral ventriculomegaly. A clinic-based neuropsychological study. Paediatric neurology clinic. Thirty-three of 41 children, previously assessed at kindergarten age, with asymmetric ventricles or unilateral ventriculomegaly identified in utero, were recruited at school age for a neuropsychological follow-up. All children, 9-11 years of age, underwent a battery of neuropsychological tests and the parents completed behavioural rating questionnaires. Results of the neuropsychological assessment and parents' questionnaires. There were no significant differences between children diagnosed with either asymmetric ventricles or unilateral ventriculomegaly in most parameters relative to the general population; the full-scale IQ scores were 103.13 ± 12.43 and 103.56 ± 10.5, respectively. A significantly lower performance was found only on one measure of attention among the unilateral ventriculomegaly group and on writing speed tasks among the asymmetric ventricles group. Both study groups showed significantly higher scores than expected in the normal population on a verbal fluency test. Comparison of both groups combined with the normative population yielded significantly lower scores only in attention tests. Yet, the clinical population showed significantly higher scores on writing accuracy, processing speed and verbal fluency and lower rates of executive dysfunction. Asymmetric ventricles or unilateral ventriculomegaly identified in utero does not appear to affect long-term mental development and school achievements. Further prospective research on a larger sample is needed in order to confirm our findings. © 2014 Royal College of Obstetricians and Gynaecologists.

    Scientific attention to cultural considerations in child neuropsychological assessment has not developed parallel to the focus these issues have received in adult and elderly neuropsychological assessment. There are limited data on the presence, magnitude, etiology, and implications of culture-related differences in cognitive test performance among children. This preliminary report reviews the available empirical literature on the current state of multicultural neuropsychological assessment in children. The review identified articles by searching PubMed and PsycINFO databases, and the tables of contents of Developmental Neuropsychology and Child Neuropsychology from 2003-2008. Of the 1,834 abstracts reviewed, ten papers met inclusion criteria for the review. Five studies were completed in America; four of these compared performance between ethnic groups while the fifth examined neighborhood level poverty indicators exclusively within African-American children. Of the five international studies, all established local normative data and/or were exploratory investigations of neuropsychological functions in specific cultural groups, including Taiwanese infants, South African youth, and bilingual British children. Taken together, the results yield important clinical and research data that begin to inform many of the complex and fascinating mechanisms by which ethnic identity and culture impact cognitive development and the neuropsychological assessment of children. A critique of the existing literature and directions for future research are provided.

    Several organizations have published guidelines for the neuropsychological care of survivors of childhood cancer. However, there is limited consensus in how these guidelines are applied. The model of neuropsychology service delivery is further complicated by the variable terminology used to describe recommended services. In an important first step to translate published guidelines into clinical practice, this paper proposes definitions for specific neuropsychological processes and services, with the goal of facilitating consistency across sites to foster future clinical program development and to clarify clinical practice guidelines. © 2017 Wiley Periodicals, Inc.

    The aim of this study is to analyze cognitive impairment in amyotrophic lateral sclerosis (ALS). Forty-four participants matched for age, sex, and educational background were enrolled as the sporadic ALS group (n = 22) and the control group (n = 22). All participants completed comprehensive neuropsychological tests, including the Mini-Mental State Examination (MMSE), the Montreal Cognitive Assessment (MoCA), the Stroop Color-Word Interference Test (SCWT), the Wisconsin Card Sorting Test (WCST), and the Frontal Assessment Battery. The participants underwent a series of 3.0 Tesla magnetic resonance imaging (MRI) scans. Resting-state functional MRI (Rs-fMRI) using the amplitude of low-frequency fluctuation (ALFF) was performed. Three-dimensional T1-weighted anatomical images obtained by voxel-based morphometry (VBM) were used to conduct correlation analyses and group comparisons with the demographic and neuropsychological characteristics. The results indicated that the decreased gray matter (GM) volume in the bilateral precentral gyri and increased ALFF values in the right parahippocampal gyrus, left inferior temporal gyrus, left anterior cingulate gyrus, right superior frontal gyrus, and left middle occipital gyrus were identified in the sporadic ALS group. The increased ALFF value in the right parahippocampal gyrus was positively correlated with ALS progression rate. The ALS patients exhibited poor performances on cognitive and executive tests, which were significantly or marginally significantly correlated with the ALFF values in the anterior cingulate gyrus and the frontal, temporal, and parahippocampal cortices. In conclusion, these findings provide evidence of an extramotor involvement and suggest that the ALFF value in the right parahippocampal gyrus could represent a potential marker to monitor disease progression.

    Many neurological therapeutic trials require a longitudinal assessment of cognitive functions. An ideal instrument for that purpose should be in accordance to the criteria of classical testing theory and, furthermore, it should be repeatable and economic in administration and interpretation. We developed NeuroCogFX, a computerized assessment battery, according to these criteria. NeuroCogFX comprises subtests for short term memory, working memory, psychomotor speed, selective attention, verbal and figural memory and verbal fluency (mean duration: 25 minutes). Age-related normative data was obtained from 244 subjects without history of neurological or psychiatric disease (age range 16 - 75 years). Forty-two subjects were re-tested after an average of 8 weeks (range: 6 - 10 weeks) in order to assess retest reliability and training effects. Retest-reliabilities were middle-sized in all but one subtest, ranging from r (12) = 0.5 to r (12) = 0.7 (2-back Test: r (12) = 0.37). For construct validation NeuroCogFX was administered in addition to a comprehensive neuropsychological assessment battery in a group of 40 healthy subjects and in 42 patients with chronic epilepsy. The test allows a valid assessment of short-term memory, reaction speed, memory and verbal fluency. NeuroCogFX is an economic, sufficiently reliable and valid instrument for the neuropsychological follow-up examination in single patients and study groups which can be administered if a comprehensive neuropsychological assessment is unavailable.

    Voice processing in neurodegenerative disease is poorly understood. Here we undertook a systematic investigation of voice processing in a cohort of patients with clinical diagnoses representing two canonical dementia syndromes: temporal variant frontotemporal lobar degeneration (n = 14) and Alzheimer’s disease (n = 22). Patient performance was compared with a healthy matched control group (n = 35). All subjects had a comprehensive neuropsychological assessment including measures of voice perception (vocal size, gender, speaker discrimination) and voice recognition (familiarity, identification, naming and cross-modal matching) and equivalent measures of face and name processing. Neuroanatomical associations of voice processing performance were assessed using voxel-based morphometry. Both disease groups showed deficits on all aspects of voice recognition and impairment was more severe in the temporal variant frontotemporal lobar degeneration group than the Alzheimer’s disease group. Face and name recognition were also impaired in both disease groups and name recognition was significantly more impaired than other modalities in the temporal variant frontotemporal lobar degeneration group. The Alzheimer’s disease group showed additional deficits of vocal gender perception and voice discrimination. The neuroanatomical analysis across both disease groups revealed common grey matter associations of familiarity, identification and cross-modal recognition in all modalities in the right temporal pole and anterior fusiform gyrus; while in the Alzheimer’s disease group, voice discrimination was associated with grey matter in the right inferior parietal lobe. The findings suggest that impairments of voice recognition are significant in both these canonical dementia syndromes but particularly severe in temporal variant frontotemporal lobar degeneration, whereas impairments of voice perception may show relative specificity for Alzheimer’s disease.

    At any point in time, there are hundreds of armed conflicts throughout the world. Neuropsychological disorders are a major cause of morbidity during and after armed conflicts. Conditions such as closed and open head injuries, acute stress disorder, post-traumatic stress disorder, depression, anxiety, and psychosis are prevalent among survivors. Herein, we summarize information on the various forms of torture, the resultant neuropsychological pathology, and treatment strategies to help survivors. Strategies to address the needs of individuals who experienced neuropsychological trauma due to armed conflicts and torture include pharmacological and psychological interventions. The former includes antidepressant, antianxiety, and antipsychotic medications. The latter includes narrative exposure therapy and trauma-focused cognitive-behavioral therapy. Neuropsychological disorders are major causes of morbidity among survivors of armed conflicts and torture. Treatment strategies must be affordable, applicable across cultures, and deliverable by individuals who understand the victims' psychosocial and ethnic background.

    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.

    Genetics and neuropsychology have historically been 2 rather distant and unrelated fields. With the very rapid advances that have been taking place in genetics, research and treatment of disorders of cognition in the 21st century are likely to be increasingly informed by individual differences in genetics and epigenetics. Although neuropsychologists are not expected to become geneticists, it is our view that increased training in genetics should become more central to training in neuropsychology. This relationship should not be unidirectional. Here we note ways in which an understanding of genetics and epigenetics can inform neuropsychology. On the other hand, given the complexity of cognitive phenotypes, neuropsychology can also play a valuable role in informing and refining genetic studies. Greater integration of the 2 should advance both fields. (c) 2015 APA, all rights reserved).

    2014-01-01

    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.

    1984-01-01

    A battery of neuropsychologic tests was administered ''blindly'' to 18 children with acute lymphocytic leukemia (ALL) who had been randomly assigned to treatment regimens with or without cranial radiation. These children were all in complete continuous remission for more than 3 1/2 years and were no longer receiving therapy. The results indicated no substantial differences between groups as a function of radiation therapy. However, decreased neuropsychologic performance was found when the entire sample was compared with population norms. These data do not support the hypothesis that cranial radiation therapy is responsible for the neuropsychologic sequelae seen in these survivors of ALL. Post hoc multiple regression analysis indicated that parental education levels accounted for more of the neuropsychologic variability seen in these children than other factors such as age at diagnosis, type of therapy, or sex of child

    Tulving's (1972) theory of memory draws a distinction between general knowledge (semantic memory) and memory for events (episodic memory). Neuropsychological studies have generally examined each type of memory in isolation, but theorists have long argued that these two forms of memory are interdependent. Here we review several lines of neuropsychological research that have explored the interdependence of episodic and semantic memory. The studies show that these forms of memory can affect each...

    This is an invited paper for a special issue on international perspectives on training and practice in clinical neuropsychology. We provide a review of the status of clinical neuropsychology in Israel, including the history of neuropsychological, educational, and accreditation requirements to become a clinical neuropsychologist and to practice clinical neuropsychology. The information is based primarily on the personal knowledge of the authors who have been practicing clinical neuropsychology for over three decades and hold various administrative and academic positions in this field. Second, we conducted three ad hoc surveys among clinical and rehabilitation psychologists; heads of academic programs for rehabilitation and neuropsychology; and heads of accredited service providers. Third, we present a literature review of publications by clinical neuropsychologists in Israel. Most of the clinical neuropsychologists are graduates of either rehabilitation or clinical training programs. The vast majority of neuropsychologists are affiliated with rehabilitation psychology. The training programs (2-3 years of graduate school) provide solid therapeutic and diagnostic skills to the students. Seventy-five percent of the participants in this survey are employed at least part-time by public or state-funded institutions. Israeli neuropsychologists are heavily involved in case management, including vocational counseling, and rehabilitation psychotherapy. Conclusions and future goals: Although clinical neuropsychologists in Israel are well educated and valued by all health professionals, there are still several challenges that must be addressed in order to further advance the field and the profession. These included the need for Hebrew-language standardized and normalized neuropsychological tests and the application of evidence-based interventions in neuropsychological rehabilitation.

  11. Neuropsychological Correlates of Hazard Perception in Older Adults.

    2016-03-01

    Hazard perception, the ability to identify and react to hazards while driving, is of growing importance in driving research, given its strong relationship to real word driving variables. Furthermore, although poor hazard perception is associated with novice drivers, recent research suggests that it declines with advanced age. In the present study, we examined the neuropsychological correlates of hazard perception in a healthy older adult sample. A total of 68 adults age 60 and older who showed no signs of dementia and were active drivers completed a battery of neuropsychological tests as well as a hazard perception task. Tests included the Repeatable Battery for the Assessment of Neuropsychological Status, Wechsler Test of Adult Reading, Trail Making Test, Block Design, Useful Field of View, and the Delis-Kaplan Executive Function System Color Word Interference Test. Hazard perception errors were related to visuospatial/constructional skills, processing speed, memory, and executive functioning skills, with a battery of tests across these domains accounting for 36.7% of the variance in hazard perception errors. Executive functioning, particularly Trail Making Test part B, emerged as a strong predictor of hazard perception ability. Consistent with prior work showing the relationship of neuropsychological performance to other measures of driving ability, neuropsychological performance was associated with hazard perception skill. Future studies should examine the relationship of neuropsychological changes in adults who are showing driving impairment and/or cognitive changes associated with Mild Cognitive Impairment or dementia.

    Full Text Available In conditions of orphanage, neuropsychological development is estimated of children aged from 3 months old up to 3 years 4 months old, without central nervous system damage and without major development defects, examined, correspondingly, in 2001 (n = 87 and in 2007 (n = 59. The estimation was performed with the use of two computer methods. The analysis of neuropsychological development estimation results by ?Profile of development? program and ?GNOM? program gave comparable results: neuropsychological development pathology group accounted for 85% and 86% correspondingly, moreover, violations are notified in all spheres of neuropsychological development without gender or age differences. However, ?Profile of development? program provides deviations in specific activity of a child in the form of a diagram, thus enabling to monitor all spheres of neuropsychological development in detail. This gives a pediatrician an opportunity to coordinate medical, psychological and pedagogic activities aimed at rehabilitation of children in conditions of deprivation.Key words: children, neuropsychological development, computer program, deprivation.(Voprosy sovremennoi pediatrii — Current Pediatrics. – 2010;9(3:26-28

    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.

    Purpose: To investigate the neuropsychological consequences of medulloblastoma in adults. Methods: Patients 18 years of age or older who had medulloblastoma and at least 3 years of disease-free survival were eligible. A battery of tests was conducted to assess global intellectual functioning, verbal ability, visuospatial ability, memory, reasoning, and academic proficiency. For the verbal memory performance, each patient was matched with two normal controls selected on the basis of age, sex, and level of education. Results: Review of the Neuro-Oncology database revealed 24 patients eligible for the study. Of these, 10 patients (6 good-risk and 4 poor-risk) agreed to participate; 7 patients were lost to follow-up; 5 lived too far away to come to the testing site, and 2 refused testing. There were four men and six women; their mean age was 36.5 years at testing and 29.9 years at surgical diagnosis. Mean dose of whole brain radiation was 34.5 Gy. Mean interval between diagnosis and testing was 79.1 months. Test results demonstrated below average intelligence quotients (mean intelligence quotient 90.2; range 67-103) and specific deficits in memory, reasoning, visuospatial ability, and arithmetic. Conclusion: Adults with medulloblastoma in a prolonged disease-free status may suffer significant cognitive deficits. We recommend further controlled, prospective studies to evaluate cognitive outcomes in this patient population in the hope that interventional strategies could be developed, or treatment modified to minimize such toxicities

    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.

    Diagnostic inaccuracies have been reported in Alzheimer's disease (AD) and Frontotemporal Dementia (FTD) using clinical data alone. The [ 11 C]-PiB PET scan offers a new method of identifying AD based on the detection of amyloid deposits. Our study investigated whether there was an agreement between neuropsychological and behavioral data and PiB findings in the diagnosis of FTD. Participants were 32 patients diagnosed with suspected FTD by clinical consensus. All participants underwent neuropsychological testing and PiB imaging. In addition, caregivers completed behavioral ratings of participants' memory, frontal behaviors, and mood. Seventeen participants were classified as PiB positive (+). Results of MANOVA and subsequent ANOVA analyses showed a significant difference on memory performance between the PiB- and PiB+groups, with the PiB- group performing better than the PiB+group. There were no significant differences between the groups on cognitive or behavioral measures of executive/frontal impairment, mood. Both groups showed similar severity of dementia. These findings provide evidence for the utility of the [ 11 C]-PiB PET scan in distinguishing between AD and FTD, with evaluation of memory at clinical diagnosis serving as a valuable indicator of the absence of FTD and consideration for an AD diagnosis. Our results would support the concern that patients who may present with primary behavioral or executive dysfunction may not necessarily have FTD, particularly if memory deficits are evident.

    Children with benign epilepsy with centro-temporal spikes (BECTS) often have language problems. Abnormal epileptic activity is found in central and temporal brain regions, which are involved in reading and semantic and syntactic comprehension. Using functional magnetic resonance imaging (fMRI), we examined reading networks in BECTS children with a new sentence reading comprehension task involving semantic and syntactic processing. Fifteen children with BECTS (age=11y 1m ± 16 m; 12 boys) and 18 healthy controls (age=11 y 8m ± 20 m; 11 boys) performed an fMRI reading comprehension task in which they read a pair of syntactically complex sentences and decided whether the target sentence (the second sentence in the pair) was true or false with respect to the first sentence. All children also underwent an exhaustive neuropsychological assessment. We demonstrated weaknesses in several cognitive domains in BECTS children. During the sentence reading fMRI task, left inferior frontal regions and bilateral temporal areas were activated in BECTS children and healthy controls. However, additional brain regions such as the left hippocampus and precuneus were activated in BECTS children. Moreover, specific activation was found in the left caudate and putamen in BECTS children but not in healthy controls. Cognitive results and accuracy during the fMRI task were associated with specific brain activation patterns. BECTS children recruited a wider network to perform the fMRI sentence reading comprehension task, with specific activation in the left dorsal striatum. BECTS cognitive performance differently predicted functional activation in frontal and temporal regions compared to controls, suggesting differences in brain network organisation that contribute to reading comprehension.

    High-functioning autism (HFA) and Aspergers syndrome (AS) are autism spectrum disorders (ASD) characterised by disturbances in social interaction, both verbal and non-verbal communication and repetitive and/or restrictive behaviour since early childhood. Symptoms appear generally during early childhood and adolescence. The increasing need to clarify diagnostic queries in advanced age led to the constitution of specialised outpatient clinics for adults involving a growing amount of HFA/AS subjects diagnosed late in life. However, thus far neuropsychological data about this group are scarce. We present a subgroup of 39 patients with HFA/AS (mean age at diagnosis 31.1 ± 8.9 years) who were consecutively diagnosed at the autism outpatient clinic at the Department of Psychiatry at the University Hospital Cologne. Autistic symptoms (autism spectrum quotient; AQ), depressive symptoms (Beck depression inventory; BDI), general intelligence (HAWIE-R), social cognition ("theory of mind", ToM) and executive functioning (COWAT) were systematically studied in comparison to a control group matched for age, education, gender and intelligence (n = 39). HFA/AS subjects presented higher AQ scores (40.4 ± 5.2) as opposed to the healthy controls (13.5 ± 4.8). Neuropsychologically, patients showed deficits in social cognition, executive functions and in subtests of HAWIE-R related to verbal comprehension and perceptual organisation as opposed to the healthy control group. The diagnosis of autistic disorders in adulthood basically relies on the clinical assessment of autistic core symptoms which were corroborated by high AQ values. The self-rating instrument AQ was found to be highly discriminative between the HFA/AS group and the healthy control group. The neuropsychological profile of adult HFA/AS patients diagnosed late in life is compatible with that of previously investigated HFA/AS populations. These findings show that such basic autism-associated deficits persist until

    With promising results in recent treatment trials for Alzheimer's disease (AD), it becomes increasingly important to distinguish AD at early stages from other causes for cognitive impairment. However, existing diagnostic methods are either invasive (lumbar punctures, PET) or inaccurate Magnetic Resonance Imaging (MRI). This study investigates the potential of neuropsychological testing (NPT) to specifically identify those patients with possible AD among a sample of 158 patients with Mild Cognitive Impairment (MCI) or dementia for various causes. Patients were divided into an early stage and a late stage group according to their Mini Mental State Examination (MMSE) score and labeled as AD or non-AD patients based on a post-mortem validated threshold of the ratio between total tau and beta amyloid in the cerebrospinal fluid (CSF; Total tau/Aβ(1-42) ratio, TB ratio). All patients completed the established Consortium to Establish a Registry for Alzheimer's Disease-Neuropsychological Assessment Battery (CERAD-NAB) test battery and two additional newly-developed neuropsychological tests (recollection and verbal comprehension) that aimed at carving out specific Alzheimer-typical deficits. Based on these test results, an underlying AD (pathologically increased TB ratio) was predicted with a machine learning algorithm. To this end, the algorithm was trained in each case on all patients except the one to predict (leave-one-out validation). In the total group, 82% of the patients could be correctly identified as AD or non-AD. In the early group with small general cognitive impairment, classification accuracy was increased to 89%. NPT thus seems to be capable of discriminating between AD patients and patients with cognitive impairment due to other neurodegenerative or vascular causes with a high accuracy, and may be used for screening in clinical routine and drug studies, especially in the early course of this disease.

    To explore the clinical, electroencephalography (EEG), neuropsychological features, and prognosis of Panayiotopoulos syndrome (PS). Of 1,794 children aged between 1 and 14 years referred for the first afebrile focal seizure, between January 1992 and December 2004, 93 (5.2%) had PS according to clinical criteria. Age at onset ranged from 1.1 to 8.6 years, and was earlier in children with more than one seizure. Autonomic seizures followed a stereotypical onset and progression. Emesis, pallor, or flushing was almost always among the first symptoms that usually culminated in vomiting (77.4% of patients). More than half (55%) of seizures were longer than 30 min but these did not appear to affect remission and number of seizures. Interictal EEG showed great variability, with 79.5% of patients showing spikes of variable localizations and evolution over time; 16.1% had background abnormalities only, and 5.4% had consistently normal EEG studies. Onsets in five ictal EEGs were posterior or anterior-left or right. On neuropsychological testing, IQ and subtests of Wechsler Intelligence Scale for Children-Revised (WISC-R) were within normal limits, although some minor statistically significant differences were found in arithmetic, comprehension, and picture arrangement in comparison with controls. Cumulative probability of recurrence was 57.6%, 45.6%, 35.1%, and 11.7% at 6, 12, 24, and 36 months, respectively, after the first seizure. Thirty-four (58.6%) of 59 patients treated with antiepileptic drugs continued having seizures before ultimate remission. PS is a uniform childhood susceptibility to autonomic seizures that is related to early age of development and with excellent prognosis with regard to seizure remission and neuropsychological development.

    Our pilot study aims to investigate the efficacy of a Short-Term (4 weeks) Psychiatric Rehabilitation Program (S-T PsyRP), without specific cognitive remediation trainings, on the neuropsychological performance and psychosocial functioning of inpatients with Major Depressive Disorder (MDD) or Bipolar Disorder (BD). Published studies with similar aims are lacking. Fifty-three inpatients with MDD and 27 with BD (type I/II) were included. The S-T PsyRP was usually performed as clinical practice at Villa San Benedetto Menni Hospital and included a variety of activities aimed at promoting personal autonomies, interpersonal/social skills, and self-care. At the beginning and the end of the hospitalization we evaluated: neuropsychological performance (cognitive tests on verbal/visual working memory, attention, visual-constructive ability, language fluency, and comprehension); psychosocial functioning by the Rehabilitation Areas Form (RAF, handbook VADO); illness severity by the Brief Psychiatric Rating Scale (BPRS). Repeated-measure ANOVA and Pearson's linear correlation were used. We found significant improvement (pneuropsychological tests except for one, in 4 out of 6 RAF psychosocial areas ("involvement in ward activities", "autonomies", "self-care", and "self-management of health") and in clinical symptoms severity. No associations were found between the amelioration of clinical symptoms and neuropsychological or psychosocial improvement. A S-T PsyRP without specific cognitive remediation trainings may improve several cognitive/functional domains in MDD or BD inpatients, probably by offering opportunities to engage in demanding problem-solving conditions and cognitively stimulating activities.

    Full Text Available Although patients with Alzheimer disease (AD share clinical and histological features regardless of age of onset, the hypothesis that early-onset AD constitutes a distinct subgroup prevails. Some authors suggest that early attention or language impairment constitute patterns of differentiation in terms of neuropsychological profile. However, investigations are not consensual in terms of cognitive domains affected in each group.Aim: To investigate whether there is early neuropsychological difference between two types of AD using the conventional dividing line of 65 years.Methods: We evaluated the results obtained in the Mini-Mental State Examination (MMSE and in a comprehensive neuropsychological battery – Battery of Lisbon for the Assessment of Dementia (BLAD, at a Dementia clinic in the University Hospital of Coimbra and a Memory Clinic. Consecutive patients with a clinical probable diagnosis of mild to moderate AD, using standard criteria (DSMIV and NINCDS-ADRDA, were selected. Statistical analysis was performed using Qui-square and U-Mann-Whitney, for categorical and non-categorical variables.Results: The sample included 280 patients: 109 with early-onset AD and 171 with a late-onset form. Groups were comparable in gender, education, severity of disease and MMSE. In BLAD, the early onset group had lower scores in Naming (p=0,025, Right-Left Orientation (p=0,029 and Praxis (p=0,001, and better performances in Orientation (p=0,001 and Visual Memory (p=0,022. After application of Bonferroni correction for multiple comparisons only Praxis and Orientation could differentiate the two groups.Discussion: The results are suggestive of dissociated profiles between early and late-onset AD. Younger patients have a major impairment in Praxis and a tendency for a great impairment in neocortical temporal functions. Late-onset form had a tendency for worse performances in Visual Memory and Orientation, suggesting a more localized disease to the limbic

    In recent years, pediatric practitioners have increasingly recognized the importance of objectively measuring performance validity during clinical assessments. Yet, no studies have examined the impact of neuropsychological consultation when invalid performance has been identified in pediatric populations and little published guidance exists for clinical management. Here we provide a conceptual model for providing feedback after noncredible performance has been detected. In a pilot study, we examine caregiver satisfaction and postconcussive symptoms following provision of this feedback for patients seen through our concussion program. Participants (N = 70) were 8-17-year-olds with a history of mild traumatic brain injury who underwent an abbreviated neuropsychological evaluation between 2 and 12 months post-injury. We examined postconcussive symptom reduction and caregiver satisfaction after neuropsychological evaluation between groups of patients who were determined to have provided noncredible effort (n = 9) and those for whom no validity concerns were present (n = 61). We found similarly high levels of caregiver satisfaction between groups and greater reduction in self-reported symptoms after feedback was provided using the model with children with noncredible presentations compared to those with credible presentations. The current study lends preliminary support to the idea that the identification and communication of invalid performance can be a beneficial clinical intervention that promotes high levels of caregiver satisfaction and a reduction in self-reported and caregiver-reported symptoms.

    There is a concern about negative cognitive effects of systemic chemotherapy. We prospectively explored self-reported cognitive problems in testicular cancer patients (TCPs) treated with and without chemotherapy. One hundred and twenty-two TCPs were interviewed about concentration and memory problems shortly after orchidectomy but before any additional treatment (baseline), and then at a median of 1 year after end of treatment (follow-up). Symptoms of psychological distress, fatigue, and peripheral neurotoxicity were assessed by questionnaires, and patients also underwent neuropsychological testing. Self-reported cognitive problems were compared between three treatments groups: no chemotherapy, one cycle of chemotherapy, and multiple cycles of chemotherapy. Variables associated with an increase of self-reported cognitive problems from baseline to follow-up were explored. Significantly larger proportions of TCPs in the two chemotherapy groups had an increase of self-reported cognitive problems from baseline to follow-up compared to the no-chemotherapy group. Increase of self-reported cognitive problems was significantly associated with psychological distress, fatigue, lower level of education, and Raynaud-like symptoms, but not with a decline in neuropsychological test performance. In this explorative study of TCPs, an increase of self-reported cognitive problems from baseline to 1-year follow-up was associated with chemotherapy and with symptoms of fatigue and psychological distress at follow-up, while no significant association was found with a decline in neuropsychological test performance.

    Anxiety disorders (ADs), the most common comorbid illnesses with bipolar disorder (BP) has been reported to associate with dopamine system. Dopamine, metabolized to 3,4-dihydroxyphenylacetic acid (DOPAC) by aldehyde dehydrogenase 2 (ALDH2), and the distribution of the ALDH2*1/*1, and ALDH2*1/*2+ALDH*2/*2 alleles in the Han Chinese general population is relatively equal. The association between dopamine metabolic enzymes and cognitive performance in patients with bipolar II disorder (BP-II) comorbid with AD is unclear. This study proposed to explore the role of ALDH2 polymorphisms on neuropsychological performance between BP-II comorbid with or without AD. One hundred ninety-seven BP-II patients with and without a comorbid AD were recruited and compared with 130 healthy controls (HCs). A polymerase chain reaction and a restriction fragment length polymorphism analysis were used to determine genotypes for ALDH2, and study participants underwent neuropsychological tests. An interaction between AD comorbidity and the ALDH2 polymorphisms was found in different domain of cognitive dysfunction in the BP-II patients. The ALDH2 polymorphisms might have different effects on the neuropsychological performance of BP-II patients with and without comorbid AD.

  7. Savant Syndrome: Clinical and Neuropsychological Features

    Full Text Available Savant syndrome defines the people who have severe developmental and mental disabilities but also have extraordinary mental skills which are missing in many people. Although general mental capacity is under average mental level, savant has excessive knowledge about one or more domains. It is accepted that as many as one in 10 persons with autistic disorder have such remarkable abilities in varying degrees, although savant syndrome occurs in other developmental disabilities or in other types of central nervous system injury or disease as well. Males outnumber females by an approximate 6 : 1 ratio in savant syndrome. Savant skills are limited to five general categories. These are music, art, calender calculating, mathematics and mechanical or spatial skills. Savant skills can also be divided into three as savants who have splinter skills, talented savants and prodigious savants. A remarkable memory welds to the special abilities determined in savant syndrome. Savant syndrome can be congenital or it can be acquired. Most often savant skills emerge in childhood, superimposed on some underlying developmental disability present at birth. However, acquired savant skills can also appear, when none were previously present, in neurotypical individuals following brain injury or disease later in infancy, childhood or adult life. Savant skills don’t depend on only rote memory. It is approved that an enhanced or spared ability to represent and manipulate highly organised domain-specific information. Various theoretic models were defined to explain the neuropsychological profile in savant syndrome. Interest in savants has a long history, stretching back to the early 18th century; nevertheless, the savant syndrome remains as much a mystery now as it did when it was first described. Given that many questions about the existence and nature of savant talent remain unanswered, it seems likely that research efforts will continue unabated.

    Frontal lobe epilepsy (FLE) is the second most frequent type of localization-related epilepsy, and it may impact neurocognitive functioning with high variability. The prevalence of neurocognitive impairment in affected children remains poorly defined. This report outlines the neuropsychological profiles and outcomes in children with new onset FLE, and the impact of epilepsy-related factors, such as seizure frequency and antiepileptic drug (AED) load, on the neurocognitive development. Twenty-three consecutive children (15 males and 8 females) with newly diagnosed cryptogenic FLE were enrolled; median age at epilepsy onset was 7 years (6-9.6 years). They underwent clinical and laboratory evaluation and neuropsychological assessment before starting AED treatment (time 0) and after one year of treatment (time 1). Twenty age-matched patients affected by idiopathic generalized epilepsy (10 male and 10 females) and eighteen age-matched healthy subjects (9 males and 9 females) were enrolled as controls and underwent the same assessment. All patients with FLE showed a significant difference in almost all assessed cognitive domains compared with controls, mainly in frontal functions and memory. At time 1, patients were divided into two groups according to epilepsy-related factors: group 1 (9 patients) with persisting seizures despite AED polytherapy, and group 2 (14 patients) with good seizure control in monotherapy. A significant difference was highlighted in almost all subtests in group 1 compared with group 2, both at time 0 and at time 1. In children with FLE showing a broad range of neurocognitive impairments, the epilepsy-related factors mostly related to a worse neurocognitive outcome are poor seizure control and the use of AED polytherapy, suggesting that epileptic discharges may have a negative impact on the functioning of the involved cerebral regions.

    Purpose The aim of our study was to determine the clinical profile of patients considered cognitive ‘responders’ to surgery in order to establish clinical variables associated with a favorable cognitive performance. Materials and Methods A total of 70 patients were included in the study. A well-validated, comprehensive standardized neurocognitive battery of tests of about 2 hours was administered. Patients were examined twice, 1-week before surgery and 1-year postoperatively. The criterion to be included in the ‘responder’ group was the following: to obtain a positive difference between post-revascularization and pre-revascularization neuropsychological assessment ≥1 standard deviation in ≥2 tests. Results Twenty-seven patients (38.6%) were cognitive responders to treatment. In bivariate analysis between responders and non-responders, presence of atrophy (P=0.003), small vessels (P=0.577), symptoms (P=0.046), and age (P=0.030) were the factors statistically significant. When comparing cognitive performance before and after carotid revascularization, significant differences were observed in semantic fluency with a lower performance after 12 months (P=0.004, d=0.29), and in the Language index (Repeatable Battery for the Assessment of Neuropsychological Status) (P=0.005, d=0.34). Conclusion Patients without neurological symptoms, of a younger age and without atrophy and white matter small vessel lesions are better cognitive responders 1-year after carotid revascularization.

    To evaluate organophosphate pesticide exposure and neuropsychological and motor performance in agricultural and non-agricultural workers in the Maule Region in Chile. Analytic cross-sectional study in 93 exposed farm workers and 84 unexposed non-agricultural workers. A battery of four neuropsychological tests was administered together with a neuro-motor physical examination. On the Weschler adult intelligence scale (WAIS-IV), exposed agricultural workers exhibited poorer performance than non-agricultural workers in verbal comprehension (β=-3.2; p=0.034) and processing speed (β=-4.4; p=0.036) and in the full scale (β=-4; p=0.016), as well as in discrimination sensitivity (β=1, p=0,009), adjusted by years of schooling and/or age. We suggest the development of policies and regulations for the control, sale and use of organophosphate pesticides and intervention strategies on safety measures aimed at the exposed population.

    In 1985 Tulving introduced the remember–know procedure, whereby subjects are asked to distinguish between memories that involve retrieval of contextual details (remembering) and memories that do not (knowing). Several studies have been reported showing age-related declines in remember hits, which has typically been interpreted as supporting dual-process theories of cognitive aging that align remembering with a recollection process and knowing with a familiarity process. Less attention has been paid to remember false alarms, or their relation to age. We reviewed the literature examining aging and remember/know judgments and show that age-related increases in remember false alarms, i.e., false remembering, are as reliable as age-related decreases in remember hits, i.e., veridical remembering. Moreover, a meta-analysis showed that the age effect size for remember hits and false alarms are similar, and larger than age effects on know hits and false alarms. We also show that the neuropsychological correlates of remember hits and false alarms differ. Neuropsychological tests of medial-temporal lobe functioning were related to remember hits, but tests of frontal-lobe functioning and age were not. By contrast, age and frontal-lobe functioning predicted unique variance in remember false alarms, but MTL functioning did not. We discuss various explanations for these findings and conclude that any comprehensive explanation of recollective experience will need to account for the processes underlying both remember hits and false alarms.

    HIV is associated with frontostriatal dysregulation and executive dysfunction. This study evaluated whether HIV-infected individuals evidence deficits in random number generation (RNG), which is a strategic task requiring paced, rule-guided production of digits. In total, 74 HIV+ adults and 54 seronegative comparison participants completed a comprehensive research neuropsychological battery. Participants produced a random digit sequence by avoiding any order and using numbers 1 through 10 for 100 s at a pace of 1 digit/s. Outcomes included intrusions, repetitions, seriation (1-2-3-4), and cycling (median length of gaps between repeating digits). HIV disease was associated with higher levels of seriation and cycling (ps  .10). Among HIV+ individuals, higher seriation was associated with neuropsychological performance including poorer auditory attention, verbal learning, and delayed memory, whereas higher cycling scores were associated with poorer delayed memory and verbal fluency (ps random sequences, which showed medium associations with higher order verbal abilities and may contribute to greater declines in everyday functioning outcomes. Future studies might examine RNG's role in health behaviors such as medical decision-making or medication adherence. © The Author 2016. Published by Oxford University Press. All rights reserved.

    In the present study, we examined relationships between neuropsychological functions and brain single photon emission computed tomography (SPECT) regional cerebral blood flow (rCBF) observed at presurgical evaluation for deep brain stimulation (DBS) of the subthalamic nucleus (STN) in advanced Parkinson's disease (PD) patients. Twenty advanced non-demented PD patients, candidates for DBS surgery, underwent perfusion brain SPECT study and neuropsychological assessment prior to surgery (range: 30-50 days). Patients were further assessed using the Unified Parkinson's Disease Rating Scale (UPDRS) and Hoehn and Yahr (H and Y) scale. During all assessments patients were ''on'' standard medication. NeuroGam software, which permits voxel by voxel analysis, was used to compare the brain perfusion of PD patients with a normal database adjusted for sex and age. Neuropsychological scores were compared to age, education and sex-adjusted normative databases. Our results indicated that the distribution of rCBF showed significant differences when compared to an age- and sex-adjusted normative database. We found impaired blood flow in 17 (85%) of our patients in the left prefrontal lobe, in 14 (70%) in the right prefrontal lobe and in 11 (55%) in the left frontal and right parietal lobes. Neuropsychological testing revealed that 18 (90%) of our patients had significant impairments in measures of executive functions (set-shifting) and 15 (75%) in response inhibition. Furthermore, we found significant correlations between measures of visual attention, executive functions and the right frontal lobe region. The presence of widespread blood flow reduction was observed mainly in the frontal lobes of dementia-free patients with advanced PD. Furthermore, performance on specific cognitive measures was highly related to perfusion brain SPECT findings. (orig.)

    Full Text Available Abstract Background Cognitive deficits and personality pathology are prevalent in opiate dependence, even during periods of remission, and likely contribute to relapse. Understanding the relationship between the two in vulnerable, opiate-addicted patients may contribute to the design of better treatment and relapse prevention strategies. Methods The Millon Multiaxial Clinical Inventory (MCMI and a series of neuropsychological tests were administered to three subject groups: 29 subjects receiving methadone maintenance treatment (MM, 27 subjects in protracted abstinence from methadone maintenance treatment (PA, and 29 healthy non-dependent comparison subjects. Relationships between MCMI scores, neuropsychological test results, and measures of substance use and treatment were examined using bivariate correlation and regression analysis. Results MCMI scores were greater in subjects with a history of opiate dependence than in comparison subjects. A significant negative correlation between MCMI scores and neuropsychological test performance was identified in all subjects. MCMI scores were stronger predictors of neuropsychological test performance than measures of drug use. Conclusion Formerly methadone-treated opiate dependent individuals in protracted opiate abstinence demonstrate a strong relationship between personality pathology and cognitive deficits. The cause of these deficits is unclear and most likely multi-factorial. This finding may be important in understanding and interpreting neuropsychological testing deficiencies in opiate-dependent subjects.

    Outline effects of functional neuroimaging on neuropsychology over the past 25 years. Functional neuroimaging methods and studies will be described that provide a historical context, offer examples of the utility of neuroimaging in specific domains, and discuss the limitations and future directions of neuroimaging in neuropsychology. Tracking the history of publications on functional neuroimaging related to neuropsychology indicates early involvement of neuropsychologists in the development of these methodologies. Initial progress in neuropsychological application of functional neuroimaging has been hampered by costs and the exposure to ionizing radiation. With rapid evolution of functional methods-in particular functional MRI (fMRI)-neuroimaging has profoundly transformed our knowledge of the brain. Its current applications span the spectrum of normative development to clinical applications. The field is moving toward applying sophisticated statistical approaches that will help elucidate distinct neural activation networks associated with specific behavioral domains. The impact of functional neuroimaging on clinical neuropsychology is more circumscribed, but the prospects remain enticing. The theoretical insights and empirical findings of functional neuroimaging have been led by many neuropsychologists and have transformed the field of behavioral neuroscience. Thus far they have had limited effects on the clinical practices of neuropsychologists. Perhaps it is time to add training in functional neuroimaging to the clinical neuropsychologist's toolkit and from there to the clinic or bedside.

    2016-07-01

    Postdoctoral recruitment in clinical neuropsychology has evolved significantly over the past two decades. Prior to 1994, there were no organized recruitment guidelines for the specialty. From 1994 to 2001, the Association of Postdoctoral Programs in Clinical Neuropsychology (APPCN) facilitated a uniform notification date where member programs agreed to not make offers prior to a specified date. In 2001, APPCN partnered with National Matching Services to administer a computerized match recruitment system. Presently, not all programs participate in the match. This often results in students applying to 'match' and 'non-match' programs which can lead to significant stress on the part of applicants and program directors. This issue has recently become the focus of journal articles and public discussions. The goals of this paper were to review the history of postdoctoral recruitment in clinical neuropsychology, review the benefits of coordinated recruitment systems, review the structure and function of the computerized match, and explain why the computerized match for postdoctoral recruitment in clinical neuropsychology is beneficial for the specialty of clinical neuropsychology.

    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.

    Full Text Available Abstract Objective: The present study investigated effect of using pump on postoperative pleural effusion in patients who underwent coronary artery bypass grafting. Methods: A total of 256 patients who underwent isolated coronary artery bypass grafting surgery in the Cardiovascular Surgery clinic were enrolled in the study. Jostra-Cobe (Model 043213 105, VLC 865, Sweden heart-lung machine was used in on-pump coronary artery bypass grafting. Off-pump coronary artery bypass grafting was performed using Octopus and Starfish. Proximal anastomoses to the aorta in both on-pump and off-pump techniques were performed by side clamps. The patients were discharged from the hospital between postoperative day 6 and day 11. Results: The incidence of postoperative right pleural effusion and bilateral pleural effusion was found to be higher as a count in Group 1 (on-pump as compared to Group 2 (off-pump. But the difference was not statistically significant [P>0.05 for right pleural effusion (P=0.893, P>0.05 for bilateral pleural effusion (P=0.780]. Left pleural effusion was encountered to be lower in Group 2 (off-pump. The difference was found to be statistically significant (P<0.05, P=0.006. Conclusion: Under the light of these results, it can be said that left pleural effusion is less prevalent in the patients that underwent off-pump coronary artery bypass grafting when compared to the patients that underwent on-pump coronary artery bypass grafting.

    Full Text Available BACKGROUND: Clinical experiences of adults who underwent surgery for esophageal atresia at birth is limited. There is some evidence that suggests considerable long-term morbidity, partly because of dysphagia, which has been reported in up to 85% of adult patients who undergo surgery for esophageal atresia. The authors hypothesized that dysphagia in this population is caused by dysmotility and/or anatomical anomalies.

    Full Text Available Introduction: There is a steady increase in the number of elderly patients with severe cardiovascular diseases who require a surgical procedure to recover some quality of life that allows them a socially meaningful existence, despite the risks.Objectives: To analyze the behavior of elderly patients who underwent cardiac surgery with cardiopulmonary bypass.Method: A descriptive, retrospective, cross-sectional study was conducted with patients over 65 years of age who underwent surgery at the Cardiocentro Ernesto Che Guevara, in Santa Clara, from January 2013 to March 2014.Results: In the study, 73.1% of patients were men; and there was a predominance of subjects between 65 and 70 years of age, accounting for 67.3%. Coronary artery bypass graft was the most prevalent type of surgery and had the longest cardiopulmonary bypass times. Hypertension was present in 98.1% of patients. The most frequent postoperative complications were renal dysfunction and severe low cardiac output, with 44.2% and 34.6% respectively.Conclusions: There was a predominance of men, the age group of 65 to 70 years, hypertension, and patients who underwent coronary artery bypass graft with prolonged cardiopulmonary bypass. Renal dysfunction was the most frequent complication.

    2013-12-01

    Full Text Available BACKGROUND: Atherosclerosis is the main cause of peripheral artery occlusive disease (PAOD of the lower limbs. Patients with PAOD often also have obstructive atherosclerosis in other arterial sites, mainly the coronary arteries. This means that patients who undergo infrainguinal bypass to treat critical ischemia have a higher risk of AMI. There are, however, few reports in the literature that have assessed this risk properly. OBJECTIVE: The aim of this study was to determine the incidence of acute myocardial infarction in patients who underwent infrainguinal bypass to treat critical ischemia of the lower limbs caused by PAOD. MATERIAL AND METHODS: A total of 64 patients who underwent 82 infrainguinal bypass operations, from February 2011 to July 2012 were studied. All patients had electrocardiograms and troponin I blood assays during the postoperative period (within 72 hours. RESULTS: There were abnormal ECG findings and elevated blood troponin I levels suggestive of AMI in five (6% of the 82 operations performed. All five had conventional surgery. The incidence of AMI as a proportion of the 52 conventional surgery cases was 9.6%. Two patients died. CONCLUSION: There was a 6% AMI incidence among patients who underwent infrainguinal bypass due to PAOD. Considering only cases operated using conventional surgery, the incidence of AMI was 9.6%.

    Various critics or "method skeptics" have contended that clinical neuropsychology is not sufficiently developed as a science to be offered as evidence in legal or trial proceedings. The present article attempts to balance the extreme position of the method skeptics with an overview of legal and research data that support forensic applications of neuropsychology. It is suggested that clinical evidence can usefully inform legal decision making and that the modern trend has been for courts to be increasingly open to such expert testimony. The relevance of studies of clinical judgement, experience, and actuarial prediction is discussed, and neuropsychological assessment validity is specifically addressed. It is concluded that the arguments of the method skeptics should guide future research and caution forensic neuropsychologists, but that a retreat from the courtroom is unwarranted.

    This study evaluated neuropsychological effects due to chronic organophosphate use among farmers with no history of acute poisoning. Fifty-seven male tree fruit farmers (exposed) were compared with 42 age-matched male cranberry/blueberry growers and hardware store owners (unexposed). Univariate analyses of covariance (reading test as covariate) comparing exposed and unexposed subjects revealed significantly slower reaction time. No other significant differences were noted on tests of concentration, visuomotor skills, memory, expressive language, or mood. Based on an exposure metric derived from detailed exposure histories, farmers were divided into high exposure (n = 40) and low exposure (n = 59) groups, and their neuropsychological performance was compared. Analysis of covariance with age and reading test score as covariates revealed that the high exposure group had significantly slower reaction time, dominant hand. Long-term use of organophosphates without evidence of an acute poisoning episode appears to produce, at most, subtle changes in neuropsychological performance.

    2013-11-01

    Discussions of and recommendations for the training of clinical neuropsychologists exist at the doctoral, internship, and post-doctoral level. With few exceptions, the literature on undergraduate preparations in clinical neuropsychology is sparse and lacks empirical evidence. In the present study, graduate-level faculty and current trainees completed surveys about graduate school preparations. Faculty expectations of minimum and ideal undergraduate training were highest for research methods, statistics, and assessment. Preferences for "goodness of fit" also emerged as important admissions factors. These results offer evidence for desirable undergraduate preparations for advanced study in clinical neuropsychology. Although undergraduate training in psychology is intentionally broad, results from this study suggest that students who desire advanced study in clinical neuropsychology need to tailor their experiences to be competitive in the application process. The findings have implications for prospective graduate students, faculty who train and mentor undergraduates, and faculty who serve on admissions committees.

    To examine the joint effect of insomnia and objective short sleep duration on neuropsychological performance. Representative cross-sectional study. Sleep laboratory. 1,741 men and women randomly selected from central Pennsylvania. None. Insomnia (n = 116) was defined by a complaint of insomnia with a duration > or = 1 year and the absence of sleep disordered breathing (SDB), while normal sleep (n = 562) was defined as the absence of insomnia, excessive daytime sleepiness, and SDB. Both groups were split according to polysomnographic sleep duration into 2 categories: > or = 6 h of sleep ("normal sleep duration") and sleep ("short sleep duration"). We compared the groups' performance on a comprehensive neuropsychological battery that measured processing speed, attention, visual memory, and verbal fluency, while controlling for age, race, gender, education, body mass index, and physical and mental health. No significant differences were detected between insomniacs and controls. However, the insomnia with short sleep duration group compared to the control with normal or short sleep duration groups showed poorer neuropsychological performance in variables such as processing speed, set-switching attention, and number of visual memory errors and omissions. In contrast, the insomnia with normal sleep duration group showed no significant deficits. Insomnia with objective short sleep duration is associated with deficits in set-switching attentional abilities, a key component of the "executive control of attention." These findings suggest that objective sleep duration may predict the severity of chronic insomnia, including its effect on neurocognitive function.

    Expanded GGGGCC hexanucleotide repeats in the non-coding region of the C9ORF72 gene was recently identified as being responsible for over 40% of the cases of amyotrophic lateral sclerosis associated with frontotemporal lobar degeneration, in various extrapyramidal syndromes including supranuclear gaze palsy and corticobasal degeneration, and in addition, has been found to be a rare genetic cause of isolated Parkinsonism. To our knowledge, there is no published data concerning the neuropsychological evaluation of patients diagnosed with idiopathic Parkinson's disease related with C9ORF72 repeat expansions. We report the results of the comprehensive neuropsychological evaluation in a newly described case in the literature (the sixth) of a patient presenting isolated idiopathic Parkinson's disease associated with C9ORF72 repeat expansions.The decrease in the patient's prefrontal functions resulted in a slight decrease in global efficiency. These abnormalities did not appear to be different, with respect to the deficit observed and the intensity of the cognitive impairment, from those classically observed in cases of sporadic idiopathic Parkinson's disease. Our patient also exhibited a significant impairment in visual gnosis. If confirmed in other patients, visuoperceptive deficits in idiopathic Parkinson's disease could represent a red flag that should prompt the clinician to perform addition diagnostic procedures. A thorough neuropsychological assessment may prove to be useful for detecting idiopathic Parkinson's disease in patients who are suspected of having repeat abnormalities of C9ORF72 expansions.

  11. Neuropsychological Predictors of Trauma Centrality in OIF/OEF Veterans

    Directory of Open Access Journals (Sweden)

    Roland P. Hart

    2017-06-01

    Full Text Available This study examined whether reduced performance on two neuropsychological tasks, cognitive flexibility and working memory, were associated with higher levels of trauma centrality. A growing body of research has shown that trauma centrality, the extent to which a person believes a potentially traumatic event has become central to their self-identity and life story, is associated with post-traumatic stress disorder (PTSD. Furthermore, PTSD is often associated with alterations in neuropsychological functioning. The relationship between neuropsychological processes and trauma centrality, however, has yet to be explored. OEF/OIF combat veterans (N = 41 completed the Post-traumatic Diagnostic Scale (PDS, the Beck Depression Inventory-II (BDI-II, the Centrality of Event Scale (CES, and on-line measures of cognitive flexibility and working memory assessed via WebNeuro. Bivariate Pearson correlations showed that CES scores were positively correlated with PDS and BDI scores, and negatively correlated with cognitive flexibility and working memory. Linear regressions revealed that working memory significantly predicted CES when controlling for depression and PTSD severity while cognitive flexibility approached significance when controlling for these same variables. This study employed a cross-sectional design, precluding causality. The small sample size, entirely male sample, and use of an online neuropsychological assessment warrant follow-up research. Although numerous studies have found an association between CES and PTSD, this is the first to suggest that neuropsychological processes underlie the construct of trauma centrality. Given the importance of maladaptive cognitive processes underlying the pathogenesis of PTSD, these data suggest that future studies aimed at examining the link between neuropsychological processes and maladaptive cognitive processes, such as trauma centrality, may help to characterize and treat PTSD.

    Cognitive impairment after aneurysmal subarachnoid hemorrhage (aSAH) is frequently detected. Here, we describe the pattern of cerebral (gray matter) atrophy and its clinical relevance after treatment of aSAH caused by a ruptured anterior cerebral artery (ACA) aneurysm. Thirty-seven aSAH patients with ACA aneurysm (17 surgical, 20 endovascular treatment) and a good or moderate clinical outcome (Glasgow Outcome Scale V or IV) and 30 controls underwent brain MRI. Voxel-based morphometric analysis was applied to compare the patients and controls. Patients also underwent a detailed neuropsychological assessment. The comparisons between controls and either all patients (n=37) or the subgroup of surgically treated patients (n=17) revealed bilateral cortical atrophy in the frontal lobes, mainly in the basal areas. The brainstem, bilateral thalamic and hypothalamic areas, and ipsilateral caudate nucleus were also involved. Small areas of atrophy were detected in temporal lobes. The hippocampus and parahippocampal gyrus showed atrophy ipsilateral to the surgical approach. In the subgroup of endovascularly treated patients (n = 15), small areas of atrophy were detected in the bilateral orbitofrontal cortex and in the thalamic region. Twenty patients (54%) showed cognitive deficits in neuropsychological assessment. Group analysis after aSAH and treatment of the ruptured ACA aneurysm revealed gray matter atrophy, principally involving the frontobasal cortical areas and hippocampus ipsilateral to the surgical approach. Areas of reduced gray matter were more pronounced after surgical than endovascular treatment. Together with possible focal cortical infarctions and brain retraction deficits in individual patients, this finding may explain the neuropsychological disturbances commonly detected after treatment of ruptured ACA aneurysms.

    Pathological gambling is an emerging psychiatric disorder that has recently gained much attention because of its increasing prevalence and devastating personal, familial, and social consequences. Although its pathophysiology is largely unknown, the shared similarities with both addiction and obsessive-compulsive spectrum disorders have suggested the possibility of common psychobiological substrates. As with many other psychiatric disorders, it is believed that pathological gambling may result from the interplay between individual vulnerability and environmental factors. The aim of this article is to offer a comprehensive review of the main neurobiological aspects of pathological gambling, with particular attention to neuropsychological and related findings. A deeper understanding of the biological correlates of pathological gambling is required in order to develop effective treatment strategies.

    Magnetic resonance imaging and a comprehensive cognitive evaluation were carried out in a series of 29 patients with mild to moderate Huntington's disease (HD). A factor analysis of the neuropsychological test scores provided three factors: A memory/speed-of-processing factor, a 'frontal' factor, and a response inhibition factor. The memory/speed factor correlated significantly with measures of caudate atrophy, frontal atrophy, and atrophy of the left (but not the right) sylvian cistern. There were no significant correlations between the 'frontal' or response inhibition factors and measures of cortical or subcortical brain atrophy. Our findings confirm that subcortical atrophy is significantly correlated with specific cognitive deficits in HD, and demonstrate that cortical atrophy also has important association with the cognitive deficits of patients with HD.

    Mindfulness is theorised to improve attention regulation and other cognitive processes. This systematic review examines whether 8-week standardised and manualised mindfulness training programs such as Mindfulness Based Cognitive Therapy (MBCT) and Mindfulness Based Stress Reduction (MBSR) enhances attention, memory and executive function abilities measured by objective neuropsychological tests. Seven databases were searched resulting in 18 studies meeting inclusion criteria for review. Overall studies did not support attention or executive function improvements. We found preliminary evidence for improvements in working memory and autobiographical memory as well as cognitive flexibility and meta-awareness. Short-term mindfulness meditation training did not enhance theorised attentional pathways. Results call into question the theoretical underpinnings of mindfulness, further highlighting the need for a comprehensive theoretical framework. Copyright © 2016 Elsevier Inc. All rights reserved.

    Pediatric bipolar disorder (PBD) has emerged as a field of research in which neuropsychological studies are continuously providing new empirical findings. Despite this, a comprehensive framework for neurocognitive impairments is still lacking, and most of the evidence remains unconnected. We addressed this question through a systematic review of neuropsychological research, with the aim of elucidating the main issues concerning this topic. A comprehensive search of databases (PubMed, PsycINFO) was performed. Published manuscripts between 1990 and January 2014 were identified. Overall, 124 studies fulfilled inclusion criteria. Methodological differences between studies required a descriptive review of findings. Evidence indicates that verbal/visual-spatial memory, processing speed, working memory, and social cognition are neurocognitive domains impaired in PBD youth. Furthermore, these deficits are greater among those who suffer acute affective symptoms, PBD type I, and/or attention deficit hyperactivity disorder (ADHD) comorbidity. In addition, several neurocognitive deficits imply certain changes in prefrontal cortex activity and are somewhat associated with psychosocial and academic disabilities. Strikingly, these deficits are consistently similar to those encountered in ADHD as well as severe mood dysregulation (SMD). Besides, some neurocognitive impairments appear before the onset of the illness and tend to maintain stable across adolescence. Finally, any therapy has not yet demonstrated to be effective on diminishing these neurocognitive impairments. More prolonged follow-up studies aimed at delineating the course of treatment and the response to it are warranted. Despite noteworthy research on the neurocognitive profile of PBD, our knowledge is still lagging behind evidence from adult counterparts. Copyright © 2014 Elsevier B.V. All rights reserved.

    US demographic and sociopolitical shifts have resulted in a rapidly growing need for culturally competent neuropsychological services. However, clinical neuropsychology as a field has not kept pace with the needs of ethnic minority clients. In this discussion we review: historical precedents and the limits of universalism in neuropsychology; ethical/professional guidelines pertinent to neuropsychological practice with ethnic minority clients; critical cultural considerations in neuropsychology; current disparities germane to practice; and challenges to the provision of services to racial/ethnic minority clients. We provide a call to action for neuropsychologists and related organizations to advance multiculturalism and diversity within the field by increasing multicultural awareness and knowledge, multicultural education and training, multicultural neuropsychological research, and the provision of culturally competent neuropsychological services to racial/ethnic minority clients. Lastly, we discuss strategies for increasing the provision of culturally competent neuropsychological services, and offer several resources to meet these goals. PMID:20373222

    Selective amygdalohippocampectomy (AHC) has evolved to encompass a variety of techniques to resect the mesial temporal lobe. To date, there have been few large-scale evaluations of trans-middle temporal gyrus selective AHC. The authors examine a large series of patients who have undergone the trans-middle temporal gyrus AHC and assess its clinical and neuropsychological impact. A series of 76 adult patients underwent selective AHC via the trans-middle temporal gyrus approach over a 10-year period, 19 of whom underwent pre- and postoperative neuropsychological evaluations. Favorable seizure response rates were achieved (92% Engel class I or II), with very low surgical morbidity and no mortality. Postoperative neuropsychological assessment revealed a decline in verbal memory for the left AHC group. No postoperative memory decline was identified for the right AHC group, but rather some improvements were noted within this group. The trans-middle temporal gyrus selective AHC is a safe and effective choice for management of medically refractory epilepsy in adults. Copyright © 2013 Elsevier Inc. All rights reserved.

    This study aimed at evaluating the voiding patterns of adult patients who underwent hypospadias repair in childhood. Following IRB approval 103 (22.7%) of 449 adult patients who underwent hypospadias repair between 1978 and 1993 responded to the following questionnaires: International Prostate Symptom Score (I-PSS) and Short Form 12 questionnaire (SF-12). Uroflowmetry (UF) was performed for all patients. The patients were divided into three groups according to the primary meatus localization. Group I had 63 patients (61.5%) treated for glanular hypospadias, group II had 19 patients (18.4%) treated for distal hypospadias, and group III comprised the remaining 21 patients (20.4%) treated for proximal hypospadias. The mean ± SD I-PSS score for all patients who responded to the questionnaire was 2.3 ± 2.4, and UF was 21.1 ± 4.3 mL/s. The patients from groups I and III had fewer urinary symptoms compared with those of the group II: 1.3 ± 1.5, 5.5 ± 2.4, and 1.6 ± 1.4, respectively (p hypospadias repair in childhood had normal or mild voiding disturbance, with no effects on their physical or mental status.

    We investigated into association of quality of life(QOL)and prognosis of breast cancer patients who underwent neoadjuvant chemotherapy(NAC). We retrospectively studied 228 patients with breast cancer who were performed NAC during a period between 2007 and 2015. TheQ OL score was measured with"The QOL Questionnaire for Cancer Patients Treated with Anticancer Drugs(QOL-ACD)". We evaluate association between QOL score with antitumor effect and prognosis. Changes in the QOL score between before and after NAC were compared as well. We divided 2 groups by QOL-ACD scoreinto high and low groups. Therapeautic effect of NAC on 75 patients were pathological complete response(pCR). QOL-ACD score was not significantly associated with pCR rate in both high and low groups(p=0.199). High group was significantly associated with higher survival rate in both of disease free survival(p=0.009, logrank)and overall survival(p=0.040, logrank). QOLACD score decreased after NAC in both of pCR and non-pCR patients. In conclusion, QOL evaluation using QOL-ACD could be an indicator of breast cancer patients' prognosis who underwent NAC.

    The role of HLA-G in several clinical conditions related to reproduction has been investigated. Important polymorphisms have been found within the 5'URR and 3'UTR regions of the HLA-G promoter. The aim of the present study was to investigate 16 SNPs in the 5'URR and 14-bp insertion/deletion (ins/del) polymorphism located in the 3'UTR region of the HLA-G gene and its possible association with the implantation outcome in couples who underwent assisted reproduction treatments (ART). The case group was composed of 25 ART couples. Ninety-four couples with two or more term pregnancies composed the control group. Polymorphism haplotype frequencies of the HLA-G were determined for both groups. The Haplotype 5, Haplotype 8 and Haplotype 11 were absolute absence in ART couples. The HLA-G*01:01:02a, HLA-G*01:01:02b alleles and the 14-bp ins polymorphism, Haplotype 2, showed an increased frequency in case women and similar distribution between case and control men. However, this susceptibility haplotype is significantly presented in case women and in couple with failure implantation after treatment, which led us to suggest a maternal effect, associated with this haplotype, once their presence in women is related to a higher number of couples who underwent ART.

    A geriatric assessment is needed to identify high-risk elderly patients with gastric cancer. However, the current geriatric assessment has been considered to be either time-consuming or subjective. The present study aimed to investigate the predictive effect of sarcopenia on the postoperative complications for elderly patients who underwent radical gastrectomy. We conducted a prospective study of patients who underwent radical gastrectomy from August 2014 to December 2015. Computed tomography-assessed lumbar skeletal muscle, handgrip strength, and gait speed were measured to define sarcopenia. Sarcopenia was present in 69 of 240 patients (28.8%) and was associated with lower body mass index, lower serum albumin, lower hemoglobin, and higher nutritional risk screening 2002 scores. Postoperative complications significantly increased in the sarcopenic patients (49.3% versus 24.6%, P sarcopenia (odds ratio: 2.959, 95% CI: 1.629-5.373, P Sarcopenia, presented as a new geriatric assessment factor, was a strong and independent risk factor for postoperative complications of elderly patients with gastric cancer.

    Full Text Available Background. S100B protein, previously proposed as a consolidated marker of brain damage in congenital heart disease (CHD newborns who underwent cardiac surgery and cardiopulmonary bypass (CPB, has been progressively abandoned due to S100B CNS extra-source such as adipose tissue. The present study investigated CHD newborns, if adipose tissue contributes significantly to S100B serum levels. Methods. We conducted a prospective study in 26 CHD infants, without preexisting neurological disorders, who underwent cardiac surgery and CPB in whom blood samples for S100B and adiponectin (ADN measurement were drawn at five perioperative time-points. Results. S100B showed a significant increase from hospital admission up to 24 h after procedure reaching its maximum peak (P0.05 have been found all along perioperative monitoring. ADN/S100B ratio pattern was identical to S100B alone with the higher peak at the end of CPB and remained higher up to 24 h from surgery. Conclusions. The present study provides evidence that, in CHD infants, S100B protein is not affected by an extra-source adipose tissue release as suggested by no changes in circulating ADN concentrations.

    Full Text Available Objective: To observe the effect of different CO2 pneumoperitoneum pressure on the stress state in patients underwent gynecological laparoscopy. Methods: A total of 90 patients who were admitted in our hospital from February, 2015 to October, 2015 for gynecological laparoscopy were included in the study and divided into groups A, B, and C according to different CO2 pneumoperitoneum pressure. The changes of HR, BP, and PetCO2 during the operation process in the three groups were recorded. The changes of stress indicators before operation (T0, 30 min during operation (T1, and 12 h after operation (T2 were compared. Results: The difference of HR, BP, and PetCO2 levels before operation among the three groups was not statistically significant (P>0.05. HR, BP, and PetCO2 levels 30 min after pneumoperitoneum were significantly elevated when compared with before operation (P0.05. PetCO2 level 30 min after pneumoperitoneum in group B was significantly higher than that in group A (P0.05. Conclusions: Low pneumoperitoneum pressure has a small effect on the stress state in patients underwent gynecological laparoscopy, will not affect the surgical operation, and can obtain a preferable muscular relaxation and vision field; therefore, it can be selected in preference.

    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.

    Previous studies document neuropsychological deficits associated with stimulant abuse, but findings are inconsistent. We identified 50 twin pairs in which only 1 member had heavy stimulant abuse (cocaine and/or amphetamines) ending at least 1 year before the evaluation. The co-twin control research design controls for familial vulnerability and makes it easier to identify neuropsychological deficits that are consequences of stimulant abuse. Subjects were administered an extensive neuropsychological test battery organized into the following 5 functions: attention, executive functioning, motor skills, intelligence, and memory. Multivariate tests showed that abusers performed significantly worse than nonabusers on functions of attention and motor skills. Within each of these functions, univariate tests showed that abusers performed significantly worse on certain tests of motor skills and attention. In contrast, abusers performed significantly better on one test of attention measuring visual vigilance. Within the abuser group, higher levels of stimulant use were largely uncorrelated with neuropsychological test scores, although a few significant correlations indicated better functioning with more stimulant use. With ideal controls, this study demonstrates that deficits in attention and motor skills persist after 1 year of abstinence from stimulant use and raises hypotheses regarding relative strengths on a vigilance task among abusers.

    Parkinson's disease (PD) is, apart from the well-known motor symptoms, also characterized by neuropsychological and emotional disturbances. However, patients also often present with a personality profile of low Novelty Seeking and high Harm Avoidance. This profile can be identified as the disease emerges, which raises the question whether these traits correlate with more fundamental neuropsychological and emotional disturbances. This study determined the neuropsychological and emotional correlates of Novelty Seeking, Harm Avoidance and two other personality traits that are often considered in PD, i.e. Reward Dependence and Persistence. Forty-three patients and 25 healthy participants were assessed with the Temperament and Character Inventory, a symptoms of depression questionnaire and neuropsychological tests. PD patients showed a higher Harm Avoidance than healthy participants, which was predicted by symptoms of depression. Groups did not differ regarding Novelty Seeking, Reward Dependence and Persistence. While cognitive flexibility was a predictor of Reward Dependence, Persistence was predicted by divergent thinking and inhibition. Novelty Seeking was not predicted by cognition or emotion. In conclusion, cognition and emotion are selectively related to personality traits in PD. Whereas Harm Avoidance covaries with emotional symptoms, Persistence and Reward Dependence are related to cognition. Alterations in personality, cognition and emotion in PD are thus not independent from each other.

    2018-02-01

    Inspired by panel discussions at various neuropsychology conferences, the aim of this paper is to share wisdom that women in neuropsychology acquired from their leadership experiences. We identified 46 women leaders in governance and academic research through reviews of organizational websites and journal editorial boards, and requested their response to brief questions via email. Twenty-one leaders provided responses to three questions formulated by the authors. This paper summarizes the primary themes for the following questions: (1) What advice would you give to a woman neuropsychologist who is seeking to move into a leadership role? Responses included: increase visibility, make connections, know yourself, be confident, and gather information. (2) What leadership style(s) works best? No respondents endorsed a 'best' leadership style; however, they suggested that leaders should know their own personal style, be open and transparent, find a shared mission, and most importantly - use a collaborative approach. (3) What helps a woman earn respect as a leader in neuropsychology? Respondents recommended that leaders should: get involved in the work, demonstrate integrity, do your homework, be dependable, and keep meetings focused. It is the authors' intent that by gathering and distilling advice from successful women leaders in neuropsychology, more women may be catalyzed to pursue leadership roles in our profession.

    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.

    Surgery and radiotherapy are the primary modalities of treatment for pediatric brain tumors. Despite the widespread use of these treatments, little is known of their acute effects (within one year posttreatment) on neuropsychological functions. An understanding of acute treatment effects may provide valuable feedback to neurosurgeons and a baseline against which delayed sequelae may be evaluated. This study compares pre- and posttherapy neuropsychological test performance of pediatric brain tumor patients categorized into two groups on the basis of treatment modalities: surgery (n = 7) and radiotherapy (n = 7). Treatment groups were composed of children aged 56 to 196 months at the time of evaluation with heterogeneous tumor diagnoses and locations. Comparisons of pretherapy findings with normative values using confidence intervals indicated that both groups performed within the average range on most measures. Outstanding deficits at baseline were observed on tests of fine-motor, psychomotor, and timed language skills, and are likely to be attributable to tumor-related effects. Comparisons of pre- versus posttherapy neuropsychological test findings indicated no significant interval changes for either group. Results suggest that surgery and radiotherapy are not associated with acute effects on neuropsychological functions

    2018-03-01

    This article considers the complexities of neuropsychological assessment and rehabilitation in brain injury when the client is illiterate, is from a foreign culture with English as a second language, and reports highly atypical childhood feral experiences prior to injury. MC was a 63-year-old woman referred for neuropsychological rehabilitation with a diagnosis of suspected St Louis encephalitis and global cognitive impairment. In formulating her clinical presentation, consideration was given to a reported history of feral childhood living with monkeys in the Colombian jungle and subsequent physical and emotional abuse. MC participated in comprehensive neuropsychological assessment and then targeted rehabilitation. Neuroimaging documented relatively focal damage in the right temporal lobe. MC's family described her as "the same but worse"; assessment and formulation indicated an exacerbation of attentional, pragmatic, arousal and executive weaknesses but with new memory and emotion recognition impairments. Rehabilitation techniques for communication and executive difficulties were successful despite the complexities of the case. The importance of carefully considered assessment and formulation in understanding MC's presentation is discussed. To the authors' knowledge, this is the only case of neuropsychological assessment and rehabilitation in brain injury involving a history of feral childhood.

    A recent study found that an earlier age of first exposure (AFE) to tackle football was associated with long-term neurocognitive impairment in retired National Football League (NFL) players. To assess the association between years of exposure to pre-high school football (PreYOE) and neuroradiological, neurological, and neuropsychological outcome measures in a different sample of retired NFL players. Cross-sectional study; Level of evidence, 3. Forty-five former NFL players were included in this study. All participants prospectively completed extensive history taking, a neurological examination, brain magnetic resonance imaging, and a comprehensive battery of neuropsychological tests. To measure the associations between PreYOE and these outcome measures, multiple regression models were utilized while controlling for several covariates. After applying a Bonferroni correction for multiple comparisons, none of the neurological, neuroradiological, or neuropsychological outcome measures yielded a significant relationship with PreYOE. A second Bonferroni-corrected analysis of a subset of these athletes with self-reported learning disability yielded no significant relationships on paper-and-pencil neurocognitive tests but did result in a significant association between learning disability and computerized indices of visual motor speed and reaction time. The current study failed to replicate the results of a prior study, which concluded that an earlier AFE to tackle football might result in long-term neurocognitive deficits. In 45 retired NFL athletes, there were no associations between PreYOE and neuroradiological, neurological, and neuropsychological outcome measures. © 2016 The Author(s).

    The patient who sustains a traumatic brain injury (TBI) typically undergoes neuroimaging studies, usually in the form of computed tomography (CT) and magnetic resonance imaging (MRI). In most cases the neuroimaging findings are clinically assessed with descriptive statements that provide qualitative information about the presence/absence of visually identifiable abnormalities; though little if any of the potential information in a scan is analyzed in any quantitative manner, except in research settings. Fortunately, major advances have been made, especially during the last decade, in regards to image quantification techniques, especially those that involve automated image analysis methods. This review argues that a systems biology approach to understanding quantitative neuroimaging findings in TBI provides an appropriate framework for better utilizing the information derived from quantitative neuroimaging and its relation with neuropsychological outcome. Different image analysis methods are reviewed in an attempt to integrate quantitative neuroimaging methods with neuropsychological outcome measures and to illustrate how different neuroimaging techniques tap different aspects of TBI-related neuropathology. Likewise, how different neuropathologies may relate to neuropsychological outcome is explored by examining how damage influences brain connectivity and neural networks. Emphasis is placed on the dynamic changes that occur following TBI and how best to capture those pathologies via different neuroimaging methods. However, traditional clinical neuropsychological techniques are not well suited for interpretation based on contemporary and advanced neuroimaging methods and network analyses. Significant improvements need to be made in the cognitive and behavioral assessment of the brain injured individual to better interface with advances in neuroimaging-based network analyses.

    The first step from the neuropsychology in Argentina was in 1883 with the thesis of Antonio Piñeiro about the brain localization of the language and vision disorders, only few years after Broca. The aim of this work has been to describe the development of the neuropsychology in Argentina and its relation with the psychology, neurology and psychiatry. The first period was into the neurology with its French school in?uence. In 1907, Jose Ingeniero published in French his book about "amusia", Cristofredo Jakob the "folia neurobiologica" where he described the organization of the human brain, Vicente Dimitri in 1933 his book "aphasia" and Bernardo de Quiros in 1959 his works about dyslexia. The psychiatry at the hospices with the German influence from Jakob developed to the modern neuropsychiatry with Juan Carlos Goldar. The argentine school of psychology by the holism and the psychoanalysis influence do not accept the neuropsychology until 1960 where was included at the school of psychology from the university of Buenos Aires (UBA) with the first linguistics works of Juan Azcoaga. At the 80, began the North American influence of the neurology with authors like Carlos Mangone (dementia), Ramon Leiguarda (apraxia), Sergio Starkstein (depression and apathy) and Ricardo Allegri (memory and Alzheimer). In 1982 the Argentine Neuropsychological Society was founded and in 1987 was the working group of dementia from the Argentine Neurological Society. At this moment, Aldo Ferreres organized the chair of neuropsychology at the school of psychology (UBA). Nowadays, the growing as discipline is in context of the psychology, neurology and psychiatry in the way of the recent cognitive neurosciences.

    The extent to which increasing age is associated with impairment in cognitive function, termed cognitive aging, may have been overestimated in prior studies. The inclusion of individuals with severe or uncontrolled systemic medical illness or prodromal neurodegenerative disease in normal aging samples is likely to bias estimates toward lower cognitive performance and inflate estimates of variability. Unbiased estimates of cognitive aging in 658 adults aged 60-84, who underwent rigorous screening to ensure their general and cognitive health, were computed. The first study screened the psychometric properties of a battery of neuropsychological tests in order to identify those with optimal properties to evaluate cognitive aging. The second study used the selected tests to compare baseline performance within 5-year age bands from 60 to 84. The first study identified a battery of 12 tests that provided reliable measures of memory, psychomotor speed, attention, and executive function and were appropriate for investigating age-related cognitive changes. The second study observed moderate to large age-related impairment for performance on tests of complex psychomotor function, category fluency, verbal learning, and verbal and visual memory. No, or only small, age effects were observed for working memory, phonemic fluency, learning of visual information, and reaction time. These data suggested that while increasing age is associated with impairment in cognitive function, this impairment is less severe and is evident only on more complex neuropsychological tests than estimated previously in samples selected using less rigorous criteria to ensure cognitive health. © The Author 2016.

    Full Text Available BackgroundChronic alcoholism and its related cognitive impairments are associated with increased social, relational, and professional deficits which have a variable overall impact on social integration. These impairments are known to have varying severities and have rarely been studied among healthy alcohol-dependent subjects with preserved psychosocial functioning. Thus, the objective of this study is to describe neuropsychological performance in this particular population.MethodTwenty-nine socially adjusted alcohol-dependent men, hospitalized for a first or second withdrawal and abstinent for 3 weeks minimum, were compared to 29 healthy non-alcoholic controls. All subjects underwent clinical and psychiatric examination, neuropsychological tests of memory (M, working memory (WM, and executive functions (EF. Comparisons were performed using Student’s t-tests or Mann–Whitney U tests.ResultsNo group differences were found on the Self-Reported Social Adjustment Scale (SAS-SR or in the Mini-Mental State Examination. Compared to controls, patients had greater episodic, spatial, and WM deficits as well as slightly altered executive functions. In contrast, their executive functions (spontaneous flexibility, criteria generation, rule maintenance, and inhibitory control were relatively preserved.ConclusionOur sample of socially and professionally integrated alcoholic patients shows fewer cognitive deficits than described in previous studies. Our results suggest that early on, alcohol-dependent subjects develop compensatory adaptation processes to preserve social function and adaptation. Minor cognitive impairments should be screened early in the disease to integrate cognitive interventions into the health-care plan to thus eventually prevent further socio-professional marginalization.

    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.

    Full Text Available Cushing’s syndrome (CS may lead to severe maternal and fetal morbidities and even mortalities in pregnancy. However, pregnancy complicates the diagnosis and treatment of CS. This study describes a 26-year-old pregnant woman admitted with hypertension-induced headache. Hormonal analyses performed due to her cushingoid phenotype revealed a diagnosis of adrenocorticotropic hormone- (ACTH- independent CS. MRI showed a 3.5 cm adenoma in her right adrenal gland. After preoperative metyrapone therapy, she underwent a successful unilateral laparoscopic adrenalectomy at 14-week gestation. Although she had a temporary postoperative adrenal insufficiency, hormonal analyses showed that she has been in remission since delivery. Findings in this patient, as well as those in previous patients, indicate that pregnancy is not an absolute contraindication for laparoscopic adrenalectomy. Rather, such surgery should be considered a safe and efficient treatment method for pregnant women with cortisol-secreting adrenal adenomas.

    The postoperative results of laparoscopic distal pancreatectomy for solid pseudopapillary neoplasm of the pancreas (SPN), including the effects of spleen-preserving resection, are still to be elucidated. Of the 139 patients who underwent laparoscopic pancreatectomy for non-cancerous tumors, 14 consecutive patients (average age, 29.6 years; 1 man, 13 women) with solitary SPN who underwent laparoscopic distal pancreatectomy between March 2004 and June 2015 were enrolled. The tumors had a mean diameter of 4.8 cm. Laparoscopic spleen-preserving distal pancreatectomy was performed in eight patients (spleen-preserving group), including two cases involving pancreatic tail preservation, and laparoscopic spleno-distal pancreatectomy was performed in six patients (standard resection group). The median operating time was 317 min, and the median blood loss was 50 mL. Postoperatively, grade B pancreatic fistulas appeared in two patients (14.3%) but resolved with conservative treatment. No patients had postoperative complications, other than pancreatic fistulas, or required reoperation. The median postoperative hospital stay was 11 days, and the postoperative mortality was zero.None of the patients had positive surgical margins or lymph nodes with metastasis. The median follow-up period did not significantly differ between the two groups (20 vs 39 months, P = 0.1368). All of the patients are alive and free from recurrent tumors without major late-phase complications. Laparoscopic distal pancreatectomy might be a suitable treatment for patients with SPN. A spleen-preserving operation is preferable for younger patients with SPN, and this study demonstrated the non-inferiority of the procedure compared to spleno-distal pancreatectomy. © 2015 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd.

    Compare the visual acuity of patients who underwent cataract surgery by phacoemulsification with IOL AcrySof(®) toric implantation versus AcrySof(®) IQ and evaluate the reduction of cylindrical diopters (CD) in the postoperative period. Analytical and retrospective study of 149 eyes with 1 or more diopters of regular symmetrical keratometric astigmatism, which underwent cataract surgery by phacoemulsification. The eyes were divided into two groups: the toric group with 85 eyes and the non-toric group with 64 eyes. In the pre-operative phase, topographic data and refraction of each eye to be operated were assessed. In the postoperative phase, refraction and visual acuity with and without correction were measured. The preoperative topographic astigmatism ranged from 1.00 to 5.6 DC in both groups. Average reduction of 1.37 CD (p<0.001) and 0.16 CD (p=0.057) was obtained for the toric and non-toric group when compared to the refractive astigmatism, respectively. Considering visual acuity without correction (NCVA), the toric group presented 44 eyes (51.7%) with NCVA of 0 logMAR (20/20) or 0.1 logMAR (20/25) and the toric group presented 7 eyes (10.93%) with these same NCVA values. The results show that patients with a significant keratometric astigmatism presented visual benefits with the toric IOL implantation. The reduction of the use of optical aids may be obtained provided aberrations of the human eye are corrected more accurately. Currently, phacoemulsification surgery has been used not only for functional improvement, but also as a refraction procedure.

    To determine the effects of total parenteral nutrition (TPN) and enteral nutrition (EN) on biochemical and clinical outcomes in pancreatic cancer patients who underwent pancreaticoduodenectomy. From the year 2006 to 2008, 60 patients who underwent pancreaticoduodenectomy in Tianjin Third Central Hospital were enrolled in this study. They were randomly divided into the EN group and the TPN group. The biochemical and clinical parameters were recorded and analyzed between the two groups. There was no significant difference in the nutritional status, liver and kidney function, and blood glucose levels between the TPN and EN groups on the preoperative day, the 1st and 3 rd postoperative days. However, on the 7th postoperative day, there was significant difference between the two groups in 24 h urinary nitrogen, serum levels of, total protein (TP), transferrin (TF), alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and γ-glutamyl transpeptadase (GGT), blood urea nitrogen (BUN) and creatinine (Cr). On the 14th postoperative day, there was a significant difference between the two groups in terms of urinary levels of 24 h nitrogen, TP, TF, retinol binding protein, ALT, AST, ALP, GGT, total bilirubin, direct bilirubin, BUN, Cr, and glucose. The incidence of delayed gastric emptying in the EN and TPN groups was 0% and 20%, respectively. Moreover, the incidence of pancreatic fistulas and hemorrhages in the EN group were 3.6% and 3.6%, versus 26.7% and 30% in the TPN group, respectively. EN is better than TPN for pancreatic cancer patients who received pancreaticoduodenectomy.

    By analyzing seroma volume changes in the patients who underwent Partial breast radiation therapy after breast conserving surgery, we try to contribute to the improvement of radiotherapy effect. Enrolled 20 patients who underwent partial breast radiation therapy by ViewRay MRIdian System were subject. After seeking for the size of the removed sample in the patients during surgery and obtained seroma volume changes on a weekly basis. On the Basis of acquired volume, it was compared with age, term from start of the first treatment after surgery, BMI (body mass index) and the extracted sample size during surgery. And using the ViewRay MRIdian RTP System, the figure was analyzed by PTV(=seroma volume + margin) to obtain a specific volume of the Partial breast radiation therapy. The changes of seroma volume from MR simulation to the first treatment (a week) is 0~5% in 8, 5~10% in 3, 10 to 15% in 2, and 20% or more in 5 people. Two patients(A, B patient) among subjects showed the biggest change. The A patient's 100% of the prescribed dose volume is 213.08 cc, PTV is 181.93 cc, seroma volume is 15.3 cc in initial plan. However, while seroma volume decreased 65.36% to 5.3 cc, 100% of the prescribed dose volume was reduced to 3.4% to 102.43 cc and PTV also did 43.6% to 102.54 cc. In the case of the B patient, seroma volume decreased 42.57% from 20.2 cc to 11.6 cc. Because of that, 100% of the prescribed dose volume decreased 8.1% and PTV also did to 40%. As the period between the first therapy and surgery is shorter, the patient is elder and the size of sample is smaller than 100 cc, the change grow bigger. It is desirable to establish an adaptive plan according to each patient's changes of seroma volume through continuous observation. Because partial breast patients is more sensitive than WBRT patients about dose conformity in accordance with the volume change.

    Although first identified over 70 years ago, Klinefelter syndrome (KS) continue to pose significant diagnostic challenges, as many patients are still misdiagnosed, or remain undiagnosed. In fact, as few as 25% of KS patients are accurately diagnosed, and most of these diagnoses are not made until adulthood. Classic characteristics of KS include small testes, infertility, hypergonadothropic hypogonadism, and cognitive impairment. However, the pathophysiology behind KS is not well understood, although genetic effects are also thought to play a role. For example, recent developments in genetics and genomics point to a fundamental change in our understanding of KS, with global epigenetic and RNA expression changes playing a central role for the phenotype.KS is also associated with more general health markers, including higher morbidity and mortality rates, and lower socio-economic status (which likely affects both morbidity and mortality). In addition, hypogonadism is associated with greater risk of of metabolic syndrome, type 2 diabetes, cardiovascular disease, breast cancer, and extragonadal germ cell tumors. Medical treatment typically focuses on testosterone replacement therapy (TRT), although the effects of this therapy has not been studied rigorously, and future studies need to evaluate the effects of TRT on metabolic risk and neurocognitive outcomes.This review presents a comprehensive, interdisciplinary examination of recent developments in genetic, endocrine and neurocognitive science, including the study of animal models regarding KS. It also provides a number of recommendations for improving the effectiveness of research and clinical practice, including neonatal KS screening programs, and a multidisciplinary approach to KS treatment from childhood until senescence.

    Marcos George de Souza Leão

    Full Text Available ABSTRACT OBJECTIVES: To evaluate through the visual analog scale (VAS the pain in patients undergoing total knee replacement (TKR with different pressures of the pneumatic tourniquet. METHODS: An observational, randomized, descriptive study on an analytical basis, with 60 patients who underwent TKR, divided into two groups, which were matched: a group where TKR was performed with tourniquet pressures of 350 mmHg (standard and the other with systolic blood pressure plus 100 mmHg (P + 100. These patients had their pain assessed by VAS at 48 h, and at the 5th and 15th days after procedure. Secondarily, the following were also measured: range of motion (ROM, complications, and blood drainage volume in each group; the data were subjected to statistical analysis. RESULTS: After data analysis, there was no statistical difference regarding the incidence of complications (p = 0.612, ROM (p = 0.202, bleeding after 24 and 48 h (p = 0.432 and p = 0.254 or in relation to VAS. No correlation was observed between time of ischemia compared to VAS and bleeding. CONCLUSIONS: The use of the pneumatic tourniquet pressure at 350 mmHg or systolic blood pressure plus 100 mmHg did not influence the pain, blood loss, ROM, and complications. Therefore the pressures at these levels are safe and do not change the surgery outcomes; the time of ischemia must be closely observed to avoid major complications.

    There are increasingly more patients seeking minimally invasive procedures, which have become more effective and safer in reducing the signs of facial aging. This study included 40 female adult patients who voluntarily underwent selected minimally invasive procedures (filling with hyaluronic acid and botulinum toxin injection) for facial rejuvenation. All patients were followed for a period of 6 months. They were evaluated with the use of questionnaires, a quality-of-life questionnaire (DLQI), the self-esteem scale of Rosenberg (EPM/Rosenberg), and a pain scale. The minimally invasive procedures resulted in improvement in quality of life and self-esteem, which were stronger the first 3 months after the procedures but remained at a higher level than that before treatment, even after 6 months. Hyaluronic acid with lidocaine in the formula is more comfortable for the patient as it makes the injection less painful.

    Basal and squamous cell carcinomas are the most common malignant cutaneous lesions affecting the nose. With the rising incidence of skin cancers, plastic surgeons increasingly face nasal reconstruction challenges. Although multiple options exist, optimal results are obtained when "like is used to repair like". We aimed to introduce a simple algorithm for the reconstruction of nasal defects with local flaps, realizing that there is always more than one option for reconstruction. We retrospectively reviewed 163 patients who underwent nasal reconstruction after excision of non-melanoma skin cancer between March 2011 and April 2014. We analyzed the location of the defects and correlated them with the techniques used to reconstruct them. There were 66 males and 97 females (age, 21-98 years). Basal cell carcinoma was diagnosed in 121 patients and squamous cell carcinoma in 42. After tumor excision, all the defects were immediately closed by either primary closure or local flap options such as Limberg, Miter, glabellar, bilobed, nasolabial, V-Y advancement, and forehead flaps. Obtaining tumor-free borders and a pleasing aesthetic result are major concerns in nasal reconstruction. Defect reconstruction and cosmesis are as important as rapid recovery and quick return to normal daily activities, and these should be considered before performing any procedure, particularly in elderly patients.

    We investigated the risk factor of perioperative asthmatic attack and effectiveness of preventing treatment for asthmatic attack before operation. We performed retrospective chart review of one hundred eleven patients with asthma underwent general anesthesia and surgical intervention from January 2006 to October 2007 in our hospital. The rate of perioperative asthmatic attack were as follows; 10.2% (5 in 49 cases) in no pretreatment group, 7.5% (3 in 40 cases) in any pretreatments except for systemic steroid, and 4.5% (1 in 22 cases) in systemic steroid pretreatment group. Neither preoperative asthma severity nor duration from the last attack had significant relevancy to perioperative attack rate. The otolaryngological surgery, especially those have nasal polyp and oral surgery had high perioperative asthma attack rate, although there was no significant difference. We recommend the systemic steroid pretreatment for asthmatic patients, especially when they have known risk factor such as administration of the systemic steroid within 6 months, or possibly new risk factor such as nasal polyp, otolaryngological and oral surgery.

    Full Text Available Background. Hypothermia in the surgical patients can be the consequence of long duration of surgical intervention, general anesthesia and low temperature in operating room. Postoperative hypothermia contributes to a number of postoperative complications such as arrhythmia, myocardial ischemia, hypertension, bleeding, wound infection, coagulopathy, prolonged effect of muscle relaxants. External heating procedures are used to prevent this condition, but some investigations reported that infusion of aminoacids during surgery can induce thermogenesis and prevent postoperative hypothermia. Case report. We reported two males who underwent major colorectal surgery for rectal carcinoma. One patient received Aminosol 15% solution, 125 ml/h, while the other did not. The esophageal temperatures in both cases were measured every 30 minutes during the operation and 60 minutes after in Intensive Care Unit. We were monitoring blood pressure, heart rate, ECG, and shivering. Patient who received aminoacids showed ameliorated postoperative hypothermia without hypertension, arrhythmia, or shivering, while the other showed all symptoms mentioned above. Conclusion. According to literature data, as well as our findings, we can conclude that intraoperative intravenous treatment with amino acid solution ameliorates postoperative hypothermia along with its complications. .

    To determine the prevalence and spontaneous resolution of congenital hydrocele diagnosed in male neonates who underwent circumcision at our centre. All male neonates presented for circumcision at the University of Benin Teaching Hospital, Benin City, Nigeria between January 2002 and December 2006 were examined for the presence of hydrocele. Those diagnosed with this condition were recruited and followed up in a surgical outpatient clinic for 2 years. The number of cases of spontaneous resolution and age at which this occurred were documented on a structured pro forma. A total of 2715 neonates were circumcised and 128 (4.7%) were diagnosed with 163 cases of hydrocele, while 27 cases in 25 (0.9%) children failed to resolve at the age of 2 years. Neonatal hydrocele was bilateral in 112 (68.7%), and there were 20 (12.3%) right and 31 (19.0%) left. Among those with hydrocele, 28.1% were delivered preterm and resolution was spontaneous in many of them, with no observed significant statistical difference to those delivered full term (P=0.4740). Of the 163 hydrocele cases, 136 (83.4%) resolved spontaneously by age 18 months with peak resolution at 4-6 months. No spontaneous resolution occurred after 18 months and no hydrocele-related complication occurred during follow up. Neonates with congenital hydrocele should be observed for spontaneous resolution for at least 18 months before being subjected to surgery.

    To describe the psychological stress and quality of life experienced by women who underwent fertility treatment in Taiwan. Cross-sectional, correlational study. Recruitment was conducted and questionnaires administered at a reproductive medicine center in Chiayi City, Taiwan. Informed consent to participate was obtained from 126 women who sought fertility treatment at the center. The Chinese Fertility Problem Inventory and Fertility Quality of Life scale were used to measure participants' levels of fertility-related stress and fertility-related quality of life. Descriptive statistics, correlation, and regression analysis were used. Overall, participants reported low levels of fertility-related stress and fertility-related quality of life; however, they had relatively high levels of stress related to need for parenthood. Women who were older, had greater body mass indexes, and consumed coffee regularly had lower fertility-related quality of life. Social and relationship concerns and stress related to need for parenthood were significant predictors of low fertility-related quality of life. In a culture in which childbearing is generally an expectation and an important part of family life, women who experience infertility are at risk to experience fertility-related stress. Social support and family consultation might be offered to improve women's fertility-related quality of life.

    Investigate the relationship between on-field markers of concussion severity and postinjury neuropsychological and symptom presentation in an athlete-specific population. Case control study. Multicenter analysis of high school and college athletes. A total of 78 athletes sustaining sports-related concussion were selected from a larger sample of 139 concussed athletes. ASSESSMENT OF PREDICTOR VARIABLES: On-field presence of disorientation, posttraumatic amnesia, retrograde amnesia, and loss of consciousness. ImPACT, a computerized neuropsychological test battery, was administered pre-season and, on average, 2 days postinjury. Good postinjury presentation (n = 44) was defined as no measurable change, relative to baseline, in terms of both ImPACT memory and symptom composite scores. Poor presentation (n = 34) was defined as a 10-point increase in symptom reporting and 10-point decrease in memory functioning (exceeding the 80% confidence interval for measurement error on ImPACT). Athletes failing to meet good or poor selection criteria (n = 61) were not included in the analysis. Odds ratios revealed that athletes demonstrating poor presentation at 2 days postinjury were over 10 times more likely (P presentation. Similarly, athletes with poor presentation were over 4 times more likely (P poor presentation groups in terms of on-field loss of consciousness. The presence of amnesia, not loss of consciousness, appears predictive of symptom and neurocognitive deficits following concussion in athletes. Athletes presenting with on-field amnesia should undergo comprehensive and individualized assessment prior to returning to sport participation. Continued refinement of sports concussion grading scales is warranted in lieu of consistent findings that brief loss of consciousness is not predictive of concussion injury severity.

    A subset of individuals with HIV-associated neurocognitive impairment experience related deficits in "real world" functioning (i.e., independently performing instrumental activities of daily living [IADL]). While performance-based tests of everyday functioning are reasonably sensitive to HIV-associated IADL declines, questions remain regarding the extent to which these tests' highly structured nature fully captures the inherent complexities of daily life. The aim of this study was to assess the predictive and ecological validity of a novel multitasking measure in HIV infection. Participants included 60 individuals with HIV infection (HIV+) and 25 demographically comparable seronegative adults (HIV-). Participants were administered a comprehensive neuropsychological battery, questionnaires assessing mood and everyday functioning, and a novel standardized test of multitasking, which involved balancing the demands of four interconnected performance-based functional tasks (i.e., financial management, cooking, medication management, and telephone communication). HIV+ individuals demonstrated significantly worse overall performance, fewer simultaneous task attempts, and increased errors on the multitasking test as compared to the HIV- group. Within the HIV+ sample, multitasking impairments were modestly associated with deficits on standard neuropsychological measures of executive functions, episodic memory, attention/working memory, and information processing speed, providing preliminary evidence for convergent validity. More importantly, multivariate prediction models revealed that multitasking deficits were uniquely predictive of IADL dependence beyond the effects of depression and global neurocognitive impairment, with excellent sensitivity (86%), but modest specificity (57%). Taken together, these data indicate that multitasking ability may play an important role in successful everyday functioning in HIV+ individuals. PsycINFO Database Record (c) 2011 APA, all rights

    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.

    Assessment of executive functions in the adult is best captured at the stage where full maturation of brain development occurs. Assessment of executive functions of children, however, is considerably more complicated. First, assessment of executive functioning in children represents a snapshot of these developing functions at a particular time linked stage, which may have implications for further development. Second, neuropsychological measures available to assess executive functions in children are limited in number and scope and may not be sensitive to the gradual developmental changes. The present article provides an overview of the salient neurodevelopmental stages of executive functioning and discusses the utilization of recently developed neuropsychological measures to assess these stages. Comments on clinical implications of these findings regarding Traumatic Brain Injury will be provided.

    There has been an increasing interest in possible connections between autism spectrum disorder (ASD) and schizophrenia in the last decade. Neuropsychological comparison studies have, however, been few. The present study examined similarities and differences in intellectual and executive functioning between adults with Asperger syndrome (AS) and adults with schizophrenic psychosis (SP). A group with AS and a group with SP were assessed neuropsychologically with WAIS-III and D-KEFS. Similarities were found between groups, as displayed by an uneven cognitive profile, limitations in working memory, processing speed and some aspects of executive functioning. Full Scale IQ was higher in the AS group. These results add to the current research illuminating similarities and differences between ASD and schizophrenia on a cognitive level.

    2013-01-01

    Collaboration between human neuropsychology and comparative neuroscience has generated invaluable contributions to our understanding of human brain evolution and function. Further cross-talk between these disciplines has the potential to continue to revolutionize these fields. Modern neuroimaging methods could be applied in a comparative context, yielding exciting new data with the potential of providing insight into brain evolution. Conversely, incorporating an evolutionary base into the theoretical perspectives from which we approach human neuropsychology could lead to novel hypotheses and testable predictions. In the spirit of these objectives, we present here a new theoretical proposal, the Inferential Brain Hypothesis, whereby the human brain is thought to be characterized by a shift from perceptual processing to inferential computation, particularly within the social realm. This shift is believed to be a driving force for the evolution of the large human cortex. PMID:22459075

    During the 1980s, the Cognitive Neuropsychology Laboratory at Good Samaritan Hospital, Portland, Oregon, made important strides in the study of brain injury. Created and headed by Oscar Marin and the author, in affiliation with the University of Oregon, the lab brought together students, fellows, and visiting experts in neurology, psychology, psychiatry, neuropsychology, neurobiology, neurophysiology, and computation. Their patient-focused collaborations produced groundbreaking research in language and its disorders, bradyphrenia, neglect, cerebellar function and impairment, and the psychology of music. The lab hosted the meeting that they documented in the influential 1985 book Attention and Performance XI: Mechanisms of Attention. The lab's members have gone on to lead distinguished careers and continue making major contributions to cognitive neuroscience.

    There is vigorous debate regarding the possibility that ADHD is overdiagnosed in boys. We investigated the impact of the gender stereotype depicting boys as inattentive and impulsive on neuropsychological assessment (observation of psychology students and child's cognitive performance). In experiment 1, after the stereotype was activated, psychology students rated a "boy," a "girl," or a "child" on a behavioral assessment scale. In experiment 2, 103 children (boys and girls) completed neuropsychological tasks under stereotype threat or neutral conditions. The gender stereotype led psychology students to assess a child's behaviors more negatively if they thought the child was a boy. Boys' performance on one cognitive score declined following stereotype threat. Regression path analyses suggested moderation by stigma consciousness. Additionally, there were mediating and suppressing (through stereotype endorsement) effects. Our results suggest that the gender stereotype might contribute to the overdiagnosis of ADHD in boys.

    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.

    Neuropsychological and neuropsychiatric disorders following open heart surgery are estimated to occur in as many as 80 per cent of all patients. They have been recognised from the very beginning of modern heart surgery. Despite a huge amount of scientific literature, data concerning incidence, the phenomenology and duration of symptoms diverge. This finding may be explained by heterogeneous aetiopathogenetic concepts and methodological and terminological problems associated with the investigation of postoperative delirium or neuropsychological and psychopathological sequelae of cardiac surgery. Nowadays, most authors agree in respect of a multifactorial pathogenesis of cognitive deficits following cardiac surgery. Factors influencing the psychopathological and neuropsychological outcome of cardiac surgery can be divided into pre-, intra- and postoperative variables. Advanced age, degree of cardiovascular impairment and other case histories, as well as history of drug abuse, are those preoperative variables that may be responsible for a postoperative cognitive decline. The predictive value of personality traits (depression and/or anxiety), however, is most controversial. Among the intraoperative variables related to the postoperative cognitive state, are e.g. the type of operation and technical procedure (micro-/macroembolism due to the way of oxygenation, pulsatile/-non-pulsatile flow) and duration of extracorporeal circulation. In the postoperative period, the duration of intubation or ICU stay and related variables (like sleep or sensory deprivation/hyperstimulation) were identified as significant predictors of neuropsychological and psychopathological alterations. Modern research focusses on neurobiochemical markers of brain injury which may serve as early predictors of a postoperative cognitive decrease. These parameters may indicate an early postoperative diagnosis and neuroprotective treatment in patients at risk.

    Integrating neuropsychology with psychoanalytic thinking and experience, this paper offers a new view of the unconscious that veers away from more traditional conceptualizations. Rather, it emphasizes the ever-present influence of ongoing unconscious processes on much of our behaviors and mental states. Importantly, this new understanding is based on the functional unity of the brain/mind. © 2017 The Authors.

    We sought to derive a 'neuropsychological intelligence quotient' (NIQ) to replace IQ testing in some routine assessments. We administered neuropsychological testing and a seven-subtest short form of the Wechsler Adult Intelligence Scale to a community sample of 394 adults aged 18-96 years. We regressed Wechsler Full Scale IQs (W-FSIQ) on 23 neuropsychological scores and derived an NIQ from 9 measures that explained significant variance in W-FSIQ. We then compared subgroups of 284 healthy and 108 unhealthy participants in NIQ and W-FSIQ to assess criterion validity, correlated NIQ and W-FSIQ scores with education level and independence for activities of daily living to assess convergent validity, and compared validity coefficients for the NIQ with those of 'hold' and 'no-hold' indices. By design, NIQ and W-FSIQ scores correlated highly (r = .84), and both were higher in healthy participants. The difference was larger for NIQ, which accounted for more variability in activities of daily living. The NIQ and 'no-hold' index were better predicted by health status and less predicted by educational status than the 'hold' index. We constructed an NIQ that correlates highly with Wechsler FSIQ. Tests required to obtain NIQ are commonly used and can be administered in about 45 min. Validity properties of NIQ and W-FSIQ are similar. The NIQ bore greater resemblance to a 'no-hold' than 'hold' index. One can obtain a reasonably accurate estimate of current Full Scale IQ without formal intelligence testing from a brief neuropsychological battery.

    Manganese exposure reportedly may have an adverse effect on CNS function and mood. Sixty-two welders with clinical histories of exposure to manganese were compared to 46 matched regional controls chosen at random from a telephone directory. The following tests were given: Wechsler Adult Intelligence Scale (WAIS-III), Wechsler Memory Scale (WMS-III), Boston Naming, WRAT-3, Cancellation H, Trail Making Tests A and B, Auditory Consonant Trigrams, Stroop, Rey-Osterreith, Animal Naming, Controlled Oral Word Association (COWAT), Test of Memory Malingering, Rey 15-item, Fingertapping, Grooved Pegboard, Dynamometer, Visual Attention Test, Lanthony d-15 Color Vision, Vistech Contrast Sensitivity, and Schirmer strips. The controls were administered a shorter battery of tests and the Rey-Osterreith, Animal Naming and some of the subtests of the WAIS-III, WMS-III were not administered. Mood tests, given to both groups, included the Symptom Checklist-40, Symptom Checklist-90-R, Profile of Mood Scale, Beck Depression Inventory II, and Beck Anxiety Inventory. Forty-seven welders and 42 controls were retained for statistical analysis after appropriate exclusions. Results showed a high rate of symptom prevalence and pronounced deficits in motor skills, visuomotor tracking speed and information processing, working memory, verbal skills (COWAT), delayed memory, and visuospatial skills. Neurological examinations compared to neuropsychological test results suggest that neuropsychologists obtain significantly more mood symptoms overall. Odds ratios indicate highly elevated risk for neuropsychological and neurological symptomatology of manganism. Mood disturbances including anxiety, depression, confusion, and impaired vision showed very high odds ratios. Neurological exams and neuropsychological tests exhibit complementarity and differences, though neuropsychological methods may be more sensitive in detecting early signs of manganism. The present study corroborates the findings of our

    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.

    The aim of this study was to evaluate the long-term outcomes of four patients with tracheal agenesis who underwent airway and esophageal/alimentary reconstruction. We reviewed the medical records of four long-term survivors of tracheal agenesis and collected the following data: age, sex, type of tracheal agenesis, method of reconstruction, nutritional management, and physical and neurological development. The patients consisted of three boys and one girl, who ranged in age from 77 to 109months. The severity of their condition was classified as Floyd's type I (n=2), II (n=1), or III (n=1). Mechanical respiratory support was not necessary in any of the cases. Esophageal/alimentary reconstruction was performed using the small intestine (n=2), a gastric tube (n=1), and the esophagus (n=1). The age at esophageal reconstruction ranged from 41 to 55months. All of the cases required enteral nutrition via gastrostomy. Three of the patients were able to swallow a small amount of liquid and one was able to take pureed food orally. The physical development of the subjects was moderately delayed-borderline in childhood. Neurological development was normal in two cases and slightly delayed in two cases. None of the long-term survivors of tracheal agenesis required the use of an artificial respirator, and their development was close to normal. Future studies should aim to elucidate the optimal method for performing esophageal reconstruction to allow tracheal agenesis patients to achieve their full oral intake.

    Roux-en-Y gastric bypass (RYGB) is a highly effective treatment for obesity and results in long-term weight loss and resolution of co-morbidities. However, weight regain may occur as soon as 1-2 years after surgery. This retrospective study aimed to investigate the prevalence of weight regain and possible preoperative predictors of this phenomenon after RYGB. An academic medical center in the United States. A total of 1426 obese patients (15.8% male) who underwent RYGB during January 2000 to 2012 and had at least a 2-year follow-up were reviewed. We included only patients who were initially successful, having achieved at least 50% excess weight loss at 1 year postoperatively. Patients were then categorized into either the weight regain group (WR) or sustained weight loss (SWL) group based upon whether they gained≥15% of their 1-year postoperative weight. Weight regain was observed in 244 patients (17.1%). Preoperative body mass index was similar between groups. Body mass index was significantly higher and percent excess weight loss was significantly lower in the WR group (Pweight regain was 19.5±9.3 kg and-.8±8.5 in the WR and SWL groups, respectively (Pweight loss. Moreover, a longer duration after RYGB was associated with weight regain. Multivariate analysis revealed that younger age was a significant predictor of weight regain even after adjusting for time since RYGB. The present study confirmed that a longer interval after RYGB was associated with weight regain. Younger age was a significant predictor of weight regain even after adjusting for time since RYGB. The findings of this study underscore the complexity of the mechanisms underlying weight loss and regain after RYGB. Future prospective studies are needed to further explore the prevalence, predictors, and mechanisms of weight regain after RYGB. Copyright © 2016 American Society for Bariatric Surgery.

    Video thoracoscopic sympathectomy is the recommended surgical treatment for primary hyperhidrosis and has a high success rate. Despite this high success rate, some patients are unresponsive and eventually need a resympathectomy. Few studies have previously analysed exclusively the results of these resympathectomies in patients with primary hyperhidrosis. None of the studies have objectively evaluated the degree of response to surgery or the improvement in quality of life after resympathectomies. This is a retrospective study, evaluating 15 patients from an initial group of 2300 patients who underwent resympathectomy after failure of the primary surgical treatment. We evaluated sympathectomy levels of resection, technical difficulties, surgical complications preoperative quality of life, response to treatment and quality-of-life improvement 30 days after each surgery. Regarding gender, 11 (73.3%) patients were women. The average age was 23.2 with SD of 5.17 years, and the mean body mass index was 20.9 (SD 2.12). Ten patients had major complaints about their hands (66%) and 5 (33%) patients about their forearms. A high degree of response to sympathectomy occurred in 73% of patients. In 11 of these patients, the improvement in quality of life was considered high, 3 showed a mild improvement and 1 did not improve. No major complications occurred; the presence of adhesions was reported in 11 patients and pleural drainage was necessary in 4 patients. Resympathectomy is an effective procedure, and it improves the quality of life in patients with primary hyperhidrosis who failed after the first surgery. © The Author 2017.

    The study objective was to report the outcomes of biventricular repair in patients with double outlet right ventricle. Patients with double outlet right ventricle who underwent biventricular repair at Fuwai Hospital from January 2005 to December 2012 were included. Patients were excluded if double outlet right ventricle was combined with atrioventricular septal defect, heterotaxy syndrome, atrioventricular discordance, or univentricular physiology. A total of 380 consecutive patients with a mean age of 1.9 ± 2.1 years (range, 1 month to 6 years) were included. Varied types of biventricular repair were customized individually. Follow-up was 90.4% complete, and the mean follow-up time was 3.4 ± 3.9 years. There were 17 (4.5%) early deaths and 7 (2.1%) late deaths. Preoperative pulmonary hypertension was the only risk factor for early mortality. Postoperative significant left ventricular outflow tract obstruction was present in 9 survivors. Patients with noncommitted ventricular septal defect had a longer crossclamp time, longer cardiopulmonary bypass time, and higher incidence of postdischarge left ventricular outflow tract obstruction. There were 4 reoperations, all of which were caused by subaortic left ventricular outflow tract obstruction. All of the pressure gradients were decreased to less than 20 mm Hg after the modified Konno procedure with an uneventful postoperative course. Optimal results of varied types of biventricular repair for double outlet right ventricle have been acquired. Although noncommitted ventricular septal defect is technically difficult, the outcomes of patients are favorable. Late-onset left ventricular outflow tract obstruction is the main reason for reoperation but can be successfully relieved by the modified Konno procedure.

  8. Newly Developed Sarcopenia as a Prognostic Factor for Survival in Patients who Underwent Liver Transplantation.

    Directory of Open Access Journals (Sweden)

    Ja Young Jeon

    Full Text Available The relationship between a perioperative change in sarcopenic status and clinical outcome of liver transplantation (LT is unknown. We investigated whether post-LT sarcopenia and changes in sarcopenic status were associated with the survival of patients.This retrospective study was based on a cohort of 145 patients from a single transplant center who during a mean of 1 year after LT underwent computed tomography imaging evaluation. The cross-sectional area of the psoas muscle of LT patients was compared with that of age- and sex-matched healthy individuals. The Cox proportional hazards regression model was used to determine whether post-LT sarcopenia and changes in sarcopenic status affect post-LT survival.The mean age at LT of the 116 male and 29 female patients was 50.2 ± 7.9 years; the mean follow-up duration was 51.6 ± 32.9 months. All pre-LT patients with sarcopenia still had sarcopenia 1 year after LT; 14 (15% patients had newly developed sarcopenia. The mean survival duration was 91.8 ± 4.2 months for non-sarcopenic patients and 80.0 ± 5.2 months for sarcopenic patients (log-rank test, p = 0.069. In subgroup analysis, newly developed sarcopenia was an independent negative predictor for post-LT survival (hazard ratio: 10.53, 95% confidence interval: 1.37-80.93, p = 0.024.Sarcopenia in LT recipients did not improve in any of the previously sarcopenic patients and newly developed within 1 year in others. Newly developed sarcopenia was associated with increased mortality. Newly developed sarcopenia can be used to stratify patients with regard to the risk of post-LT mortality.

    To identify clinical or cognitive measures either predictive of illness trajectory or altered with sustained weight recovery in adult women with anorexia nervosa. Participants were recruited from prior studies of women with anorexia nervosa (AN-C) and in weight-recovery following anorexia nervosa (AN-WR). Participants completed a neuropsychological battery at baseline and clinical assessments at both baseline and follow-up. Groups based on clinical outcome (continued eating disorder, AN-CC; newly in recovery, AN-CR; sustained weight-recovery, AN-WR) were compared by using one-way ANOVAs with Bonferroni-corrected post hoc comparisons. Women with continued eating disorder had poorer neuropsychological function and self-competence at baseline than AN-CR. AN-CR showed changes in depression and externalizing bias, a measure of self-related attributions. AN-WR differed from both AN-CC and AN-CR at baseline in externalizing bias, but only from AN-CC at outcome. Neuropsychological function when recently ill may be a prognostic factor, while externalizing bias may provide a clinical target for recovery.

  10. Consolidated Standards of Reporting Trials (CONSORT): considerations for neuropsychological research.

    Miller, Justin B; Schoenberg, Mike R; Bilder, Robert M

    2014-01-01

    Evidence-based medicine (EBM) is a pillar of clinical medicine (Sackett, Rosenberg, Gray, Haynes, & Richardson, 1996 ), but only recently has this been systematically discussed within the context of clinical neuropsychology (e.g., Chelune, 2010 ). Across the medical sciences, randomized controlled trials (RCTs) are often considered the most important source of evidence for treatment efficacy. To facilitate the conduct, dissemination, and evaluation of research findings, reporting standards have been implemented, including the Consolidated Standards of Reporting Trials (CONSORT) statement. This paper considers the implications of the CONSORT statement for the reporting of clinical trials that include neuropsychological endpoints. Adopting specific guidelines for trials involving neuropsychology endpoints will ultimately serve to strengthen the empirical evidence base by increasing uniformity within the literature, decrease ambiguity in reporting, improving trial design, and fostering methodological transparency. Implementing uniform reporting standards will also facilitate meta-analytic review of evidence from published trials, benefiting researchers, clinicians, educators and practitioners, as well as journal editors, reviewers, and ultimately, health care consumers.

    Full Text Available Pablo Valdez, Candelaria Ramírez, Aída GarcíaLaboratory of Psychophysiology, School of Psychology, University of Nuevo León, Monterrey, Nuevo León, MéxicoAbstract: Circadian variations have been found in human performance, including the efficiency to execute many tasks, such as sensory, motor, reaction time, time estimation, memory, verbal, arithmetic calculations, and simulated driving tasks. Performance increases during the day and decreases during the night. Circadian rhythms have been found in three basic neuropsychological processes (attention, working memory, and executive functions, which may explain oscillations in the performance of many tasks. The time course of circadian rhythms in cognitive performance may be modified significantly in patients with brain disorders, due to chronotype, age, alterations of the circadian rhythm, sleep deprivation, type of disorder, and medication. This review analyzes the recent results on circadian rhythms in cognitive performance, as well as the implications of these rhythms for the neuropsychological assessment of patients with brain disorders such as traumatic head injury, stroke, dementia, developmental disorders, and psychiatric disorders.Keywords: human circadian rhythms, cognitive performance, neuropsychological assessment, attention, working memory, executive functions

    To examine the relationship between third ventricular width, a measure of thalamic brain atrophy, and motor vehicle violation type and frequency in a cohort of patients with multiple sclerosis (MS). Retrospective cohort study. Tertiary care university hospital. Thirty-five individuals with clinically confirmed relapsing-remitting multiple sclerosis and 35 age-, sex-, and education-matched community-dwelling healthy comparisons (N=70). Participants were aged between 25 and 65 years. Not applicable. Data on motor vehicle violations were obtained from an online database (Iowa Courts Online). The violations were categorized as follows: (1) speeding, (2) nonmoving safety, (3) administrative, (4) alcohol-related offense, (5) moving safety, and (6) total violations. Neuropsychological performance in all major cognitive domains was obtained. Thalamic atrophy for the patients with MS was determined via third ventricular width measurement. The MS group had a greater number of overall violations, administrative violations, and nonmoving safety violations. The groups differed on neuropsychological tasks measuring visuospatial skills, speeded language, learning, and executive functioning, after controlling for affective symptoms. Third ventricular width was associated with total violations as well as moving safety violations. Finally, third ventricular width accounted for a significant variance in driving violation frequency above and beyond demographic variables and neuropsychological factors. There is an increased frequency of motor vehicle violations among patients with multiple sclerosis, and the number of violations can be predicted by thalamic brain atrophy.

    Full Text Available Triple A syndrome is an autosomal recessive disorder characterized by the triad of adrenocorticotropic hormone resistant adrenal insufficiency, achalasia, and alacrima. Our aim was to describe the neuropsychological characteristics and the cooccurring psychopathological and neurological disorders in an Italian male child suffering from Triple A syndrome at the time of admission (T0 and after one year of follow-up (T1. Many difficulties were observed in the motor domain, as well as in manual dexterity and static/dynamic balance domains of the motor task over time. In sharp contrast with previous literature reports on frequent mild cognitive dysfunction in patients with Triple A syndrome, our child did not show any mental retardation. By contrast, he showed an average IQ at T0 with a slight improvement at T1. To our knowledge, this report is the first describing neuropsychological profile and co-occurring psychopathological problems in a child with Triple A syndrome. Considering that the Triple A syndrome is a progressive disorder which can take years to develop the full-blown clinical picture, these patients require periodical medical controls. Moreover, assessment of neuropsychological and psychopathological features should be performed in patients with this disease, in order to underline the variability of this syndrome.

  14. Neuropsychological intervention in dyslexia: two studies on British pupils.

    The theoretical context of this research is developmental neuropsychology--in particular, the educational implications for the classification of and intervention in specific developmental dyslexia (SDD). Controlled and validated research can help identify optimal teaching methods for groups and individuals. Within this framework, neuropsychological theory can be explored as a medium for improving intervention for pupils with SDD. Neuropsychological stimulation cannot change the macro aspects of the brain but can change its "finetuning" and its response to written text. Within the psycho-neurological approaches, Bakker (1979, 1990, 1998) developed both a diagnostic procedure and empirically investigated intervention procedures. The theory rests on the Balance Model of learning to read, in which differential hemisphere involvement is implicated in beginning and advanced reading. Intervention can take place via hemisphere-specific stimulation using visual or tactile stimulation or hemisphere-alluding stimulation using modified text. Two investigations are presented, one experimental and another clinical. The results support the validity of dyslexia subtyping and the effectiveness of the treatment methods.

    Garrido, M J; Fernández-Guinea, S

    There are various published studies showing that chronic alcoholics present cognitive deficit. In this conference we would like to review the most actual studies focusing on the neuropsychological alterations as consequences of the long and abusive alcohol intake. We also will analyse the involvement of these deficit in a complex task as driving. The long and abusive alcohol intake produces an affectation of the central nervous system. We could observe its consequences both in short and long term. Attention and memory deficit and a slowness of information processing are very common. However, complete neuropsychological assessment and rehabilitation programs are convenient. This is an important topic if we consider the high number of traffic accidents in which alcohol intake is one of the possible causes. Therefore, it is necessary to pay attention to the persons working daily with a car, such as taxi or bus drivers, especially those of them who are alcoholics in abstinence, chronic alcoholics and people who suffer from alcohol abuse. The control of this situation and the publicity about neuropsychological sequels of alcoholism could contribute in an efficient way towards safety in road.

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

    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.

    New lines of translational, interdisciplinary research are emerging among different fields of the neurosciences, which often point at clinical neuropsychology as the hinge discipline capable of linking the basic findings with their clinical implications and thereby endow them with some meaning for phenomenological experience. To establish the great lines of progress made in the fields of neuroscience and neuropsychology in recent years, so as to be able to foresee the strategic lines and priorities of neuroscience in the near future. To achieve this aim, the first step will be to identify the changes of paradigm that have taken place in the areas of neuroscience and psychology in the last two decades. The next step will be to propose new topics and fields of application that these changes in paradigm offer and demand from neuroscience. The false dichotomies of genes versus environment, mind versus brain, and reason versus emotion are considered, as are the new applications of neuropsychology to the understanding of psychopathological disorders, from the neurodegenerative to neurodevelopment, from 'dirty' drugs to cognitive and affective enhancers.

    To determine the extent to which specific neuropsychological measures are in common use around the world for the assessment of children who are candidates for epilepsy surgery. As part of the work of the International League Against Epilepsy Pediatric Surgical Task Force, a survey was developed and distributed online. The survey consisted of questions related to demographics, training experience, general practice, and specific measures used and at what frequency. Seventy-eight clinicians with an average of 13.5 years of experience from 19 countries responded to the survey; 69% were English-speaking. Pre- and post-neuropsychological evaluations were conducted with a majority of children undergoing surgical resection for epilepsy. There was high consistency (>90%) among the domains evaluated, while consistency rate among specific measures was more variable (range: 0-100%). Consistency rates were also lower among respondents in non-English-speaking countries. For English-speaking respondents, at least one measure within each domain was used by a majority (>75%) of clinicians; 19 specific measures met this criterion. There is consensus of measures used in neuropsychological studies of pediatric epilepsy patients which provides a basis for determining which measures to include in establishing a collaborative data repository to study surgical outcomes of pediatric epilepsy. Challenges include selecting measures that promote collaboration with centers in non-English-speaking countries and providing data from children under age 5.

  19. Cognitive neuropsychology and its vicissitudes: The fate of Caramazza's axioms.

    2015-01-01

    Cognitive neuropsychology is characterized as the discipline in which one draws conclusions about the organization of the normal cognitive systems from the behaviour of brain-damaged individuals. In a series of papers, Caramazza, later in collaboration with McCloskey, put forward four assumptions as the bridge principles for making such inferences. Four potential pitfalls, one for each axiom, are discussed with respect to the use of single-case methods. Two of the pitfalls also apply to case series and group study procedures, and the other two are held to be indirectly testable or avoidable. Moreover, four other pitfalls are held to apply to case series or group study methods. It is held that inferences from single-case procedures may profitably be supported or rejected using case series/group study methods, but also that analogous support needs to be given in the other direction for functionally based case series or group studies. It is argued that at least six types of neuropsychological method are valuable for extrapolation to theories of the normal cognitive system but that the single- or multiple-case study remains a critical part of cognitive neuropsychology's methods.

    Schwartz and Dell (2010) advocated for a major role for case series investigations in cognitive neuropsychology. They defined the key features of this approach and presented a number of arguments and examples illustrating the benefits of case series studies and their contribution to computational cognitive neuropsychology. In the Special Issue on "Case Series in Cognitive Neuropsychology" there are six commentaries on Schwartz and Dell as well as a response to the six commentaries by Dell and Schwartz (2011 this issue). In this paper, I provide a brief summary of the key points made in Schwartz and Dell, and I review the promise and perils of case series design as revealed by the six commentaries. I conclude by placing the set of papers within a broader perspective, providing some clarification of the historical record on case series and single-case approaches, raising some cautionary notes for case series studies and situating both case series and single-case approaches within the larger context of theory development in the cognitive sciences.

  1. Neuropsychological characteristics of Gulf War illness: A meta-analysis.

    Patricia A Janulewicz

    Full Text Available Gulf War illness (GWI is a disorder related to military service in the 1991 GW. Prominent symptoms include fatigue, pain and cognitive problems. These symptoms were reported by GW Veterans (GWV immediately after the war and were eventually incorporated into case definitions of GWI. Neuropsychological function in GW veterans has been studied both among deployed GWV and in GWV diagnosed with GWI. Results have been inconsistent between and across GW populations. The purpose of the present investigation was to better characterize neuropsychological function in this veteran population.Meta-analysis techniques were applied to published studies on neuropsychological performance in GWV to identify domains of dysfunction in deployed vs. non-deployed GW-era veterans and symptomatic vs. non-symptomatic GWVs.Significantly decreased performance was found in three functional domains: attention and executive function, visuospatial skills and learning/memory.These findings document the cognitive decrements associated with GW service, validate current GWI case definitions using cognitive criteria, and identify test measures for use in GWI research assessing GWI treatment trial efficacy.

    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.

    Neuropsychological deficits are common in various cerebrovascular, neurodegenerative and traumatic pathologies. Neuropsychological rehabilitation refers to a set of interventions that aim to improve a person's ability to perform cognitive tasks by retraining previously learned skills and teaching compensatory strategies. However, today there are some relevant points that need of further investigations. In 2007, a Task Force was set up under the auspices of several scientific societies that operate in the field of psychology, neuropsychology, rehabilitation and neurology (AIP, GIRN, SIMFER, SIN, SINP, and SPAN) with the aim to clarify the theoretical background of neuropsychological rehabilitation and to assess the diagnostic instruments and the treatments available to date. This consensus conference (CC), using methods derived from those of Evidence-Based-Medicine (EMB), evaluated several points, including: a) legal aspects; b) epidemiological aspects; c) neuropsychological rehabilitation of attentional and executive disorders; d) neuropsychological rehabilitation of speech/language disorders; e) neuropsychological rehabilitation of visual field defects; f) neuropsychological rehabilitation of neglect; g) neuropsychological rehabilitation of memory disorders; h) cognitive rehabilitation of arm apraxia; i) neuropsychological rehabilitation of Alzheimer disease; j) rehabilitation of multiple sclerosis; k) rehabilitation of severe brain injuries; l) rehabilitation of mild to moderate brain injuries; m) rehabilitation of behavioral disorders in severe brain injuries. Then, CC submitted to a specific Jury a final report with summary tables and questions. The final meeting of the Jury was held in Siena in February 2010.

    Although psychology has become a female-dominated field, this pattern of gender representation has not held true within the specialty of neuropsychology. In recent years more women have been pursuing careers in neuropsychology, and while the balance of male and female neuropsychologists as a whole has shifted, it is unclear whether the gender composition of leadership has also changed. Our goal was to survey various neuropsychological organizations, training programs, editorial boards, and organizations granting board certification to determine the current gender composition of leadership positions within neuropsychology. A literature review was conducted to examine past trends of gender composition in neuropsychology, psychology, medicine, and academia. Data on current gender compositions of the field were culled from publicly available websites and through personal communication with representatives from major psychological and neuropsychological organizations. We found that the overall composition of the field has changed over time, but notable gender disparities in leadership positions remain. Women still comprise the minority of leadership positions within most neuropsychological organizations, editorial boards for neuropsychology journals, and fellow positions in major neuropsychological organizations. More equitable representation has been achieved in the directorships of training programs and ABPP/ABCN board certification. We review the historical trends in gender discrepancies in leadership in neuropsychology and discuss these within the broader arenas of academia, research, and medicine. We conclude with a summary addressing potential causes for these discrepancies, including work-life balance issues, discrimination, institutional bias, and various other factors. We also provide pragmatic suggestions to help address these continued disparities.

    To review the development, application, and value of neuropsychology, and the standard education and training pathway for neuropsychologists or clinical neuropsychologists in Hong Kong. The information provided here was gathered via a literature review of the status of neuropsychology and the validity of commonly adopted neuropsychological tests in Hong Kong. Additional details were acquired via the internet about local tertiary education curricula and the related requirements, the availability of professional associations for licensure or board certification, and relevant statistics/surveys conducted by the government. Some information about the clinical practice of neuropsychology was collected through personal communication with local clinical psychologists. The development of neuropsychology in Hong Kong over the past 20 years is rapid and productive, given the increasing application of advanced neuroimaging techniques, neuropsychological tests, and opportunities for exchanging up-to-date neuropsychological knowledge and professional training through international conferences, workshops, and seminars. Given that neuropsychology services are often provided by clinical psychologists who are master's degree graduates in clinical psychology, the relatively limited training in neuropsychological knowledge and skills and the lack of division for membership or mandatory registration as a neuropsychologist/clinical neuropsychologist may have an impact on the quality of clinical neuropsychological services and the development of this specialty. These findings signify a need for further improvement or refinement of educational and training pathways for neuropsychologist or clinical neuropsychologist along with the recognition of its value in clinical practice through registration of different disciplines of psychology in Hong Kong.

    HLA-G codes for a non-classical class I (Ib) protein which is mainly expressed in trophoblast cells. Many pieces of evidence pointed out its essential role conferring immunological tolerance to the fetus. Some HLA-G alleles have been linked to enhanced or reduced HLA-G protein levels expression, which have been associated with reproductive failure. In this study 33 couples undergoing ART (assisted reproduction treatment; n=66) and 120 couples who conceived naturally (controls; n=240) were enrolled in the study. Genotyping was performed by SBT and tagged an 1837bp at 5'URR as well as exons 2, 3 and4 of HLA-G. Alleles, genotypes and haplotypes were compared between infertile and control groups using Fisher Exact Test. The haplotype HLA-G ∗ 010101b/HLA-G ∗ 01:01:01 showed statistically significant higher frequency in control groups. The immunogenetics of infertility is complex and might be dependent on different genes involved in the establishment of a successful pregnancy. A better understanding of HLA-G alleles and haplotypes structure and how the genetic diversity at their regulatory sites could impact on their level of expression and build up the susceptibility or protection conditions may shed light on the comprehension of immunogenetics mechanisms acting at the fetus-maternal interface.

    2017-11-01

    Full Text Available BackgroundRecent studies have suggested that cognitive functions in patients with neurocognitive disorders have a significant role in the pathogenic mechanisms of frailty. Although pre-frailty is considered an intermediate, preclinical state, epidemiological research has begun to dislodge cognition and frailty into their specific subcomponents to understand the relationship among them. We aim to analyse the possible association between pre-frailty and neuropsychological variables to outline which factors can contribute to minor and major neurocognitive disorders.Methods60 subjects complaining of different cognitive deficits underwent a deep-in-wide frailty and neuropsychological assessment. We conducted three multiple linear regression analyses adjusted for a combination of demographic measures and involving several neuropsychological–behavioural parameters selected by the literature on physical frailty.ResultsWe found a significant association between frailty—as measured by the multidimensional prognostic index (MPI—and action monitoring and monetary gain (cognitive domain, depression and disinhibition (behavioural domain. Moreover, an association between MPI and impaired awareness for instrumental activities disabilities exists.ConclusionWe propose a novel framework for understanding frailty associated with metacognitive–executive dysfunction.

    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.

    Recent work using novel neuroimaging methods has revealed shorter white matter fiber bundle length (FBL) in older compared to younger adults. Shorter FBL also corresponds to poorer performance on cognitive measures sensitive to advanced age. However, it is unclear if individual factors such as cognitive reserve (CR) effectively moderate the relationship between FBL and cognitive performance. This study examined CR as a potential moderator of cognitive performance and brain integrity as defined by FBL. Sixty-three healthy adults underwent neuropsychological evaluation and 3T brain magnetic resonance imaging. Cognitive performance was measured using the Repeatable Battery of Assessment of Neuropsychological Status (RBANS). FBL was quantified from tractography tracings of white matter fiber bundles, derived from the diffusion tensor imaging. CR was determined by estimated premorbid IQ. Analyses revealed that lower scores on the RBANS were associated with shorter whole brain FBL (p = 0.04) and lower CR (p = 0.01) CR moderated the relationship between whole brain FBL and RBANS score (p performance (p = 0.03). These results demonstrate that lower cognitive performance on the RBANS is more common with low CR and short FBL. On the contrary, when individuals have high CR, the relationship between FBL and cognitive performance is attenuated. Overall, CR protects older adults against lower cognitive performance despite age-associated reductions in FBL.

    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

    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, ClinicalTrials.gov 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

    During awake craniotomy for tumor resection, a neuropsychologist (NP) is regarded as a highly valuable partner for neurosurgeons. However, some centers do not routinely involve an NP, and data to support the high influence of the NP on the perioperative course of patients are mostly lacking. The aim of this study was to investigate whether there is a difference in clinical outcomes between patients who underwent awake craniotomy with and without the attendance of an NP. Our analysis included 61 patients, all operated on for resection of a presumably language-eloquent glioma during an awake procedure. Of these 61 cases, 47 surgeries were done with neuropsychological support (NP group), whereas 14 surgeries were performed without an NP (non-NP group) due to a language barrier between the NP and the patient. For these patients, neuropsychological assessment was provided by a bilingual resident. Both groups were highly comparable regarding age, gender, preoperative language function, and tumor grades (glioma WHO grades 1-4). Gross total resection (GTR) was achieved more frequently in the NP group (NP vs. non-NP: 61.7 vs. 28.6%, P  = 0.04), which also had shorter durations of surgery (NP vs. non-NP: 240.7 ± 45.7 vs. 286.6 ± 54.8 min, P  vs. postoperative imaging) was lower in the NP group (NP vs. non-NP: 19.1 vs. 42.9%, P  = 0.09), but no difference was observed in terms of permanent surgery-related language deterioration (NP vs. non-NP: 6.4 vs. 14.3%, P  = 0.48). We need professional neuropsychological evaluation during awake craniotomies for removal of presumably language-eloquent gliomas. Although these procedures are routinely carried out with an NP, this is one of the first studies to provide data supporting the NP's crucial role. Despite the small group size, our study shows statistically significant results, with higher rates of GTR and shorter durations of surgery among patients of the NP group. Moreover, our data emphasize the common

    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.

    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.

    2016-11-01

    This was an invited paper on the history and current status of neuropsychology in South Africa. Information was gathered from literature searches, personal communication, and the authors' experiences while occupying relevant professional and academic positions for over 30 years. Since its origins in the 1950s, the development of neuropsychology in South Africa has faced numerous challenges, against a background of extreme sociocultural and socioeconomic disparity in the country that is on-going. The creation of the South African Clinical Neuropsychological Society in the 1980s, a credentialing and training body, gave impetus to the discipline. In the absence of a neuropsychology category within the South African professional framework, university instruction has been ad hoc with vastly different levels of competency depending on the institution involved. The small number of practitioners and/or academics involved in neuropsychology includes mainly masters, and some doctoral level psychologists registered in clinical, counseling or educational categories. A prime emphasis of neuropsychological research has been local norming of psychometric tests to facilitate valid assessment practices in the country. South Africa is on the cusp of achieving a hard-won neuropsychology professional register. It is anticipated that this development will provide impetus to the discipline by promoting training programs, the creation of neuropsychology posts, wider service delivery, and increased research funding. Despite significant challenges in a culturally diverse, developing country, neuropsychology has evolved sufficiently to warrant the creation of a separate category in the professional framework. This development will facilitate training, research, and services in the country.

    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.

    2015-05-01

    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.

    Full Text Available Mild cognitive impairment (MCI is frequent in Parkinson’s disease (PD. Recently proposed criteria for MCI in PD (PD-MCI indicate level I diagnosis based on abbreviated assessment and level II based on comprehensive neuropsychological evaluation. The study explored the sensitivity and specificity of the Italian versions of three neuropsychological tests for level I diagnosis of PD-MCI. We recruited 100 consecutive PD patients. After screening for inclusion criteria, 43 patients were included. The sensitivity and specificity of the Mini Mental State Examination (MMSE, the Montreal Cognitive Assessment (MoCA, and the Addenbrooke’s Cognitive Examination Revised (ACE-R in comparison to level II diagnosis of PD-MCI were examined. PD-MCI was diagnosed (level II in 51% of patients. Disease duration was significantly longer and PD motor scales were more severely impaired in MCI group. The receiver-operator characteristics curve documented nonsignificant difference in the performance of the three tests, with slight advantage of MMSE (corrected data. The time of administration favored MMSE. In Italian-speaking PD patients, MMSE might represent a good screening tool for PD-MCI, because of the shorter time of administration and the performance comparable to those of MoCA and ACE-R. Further studies are needed to validate the new PD-MCI criteria across different languages and cultures.

  2. Neuropsychological findings associated with Panayiotopoulos syndrome in three children.

    2016-01-01

    Panayiotopoulos syndrome is a common idiopathic benign epilepsy that has a peak age of onset in early childhood. The syndrome is multifocal and shows significant electroencephalogram (EEG) variability, with occipital predominance. Although a benign syndrome often refers to the absence of neurological and neuropsychological deficits, the syndrome has recently been associated with cognitive impairments. Also, despite frequent occipital EEG abnormalities, research regarding the visual functioning of patients is less reported and often contradictory. The purpose of this study was to gain additional knowledge regarding the neurocognitive functioning of patients with Panayiotopoulos syndrome and specifically to address any visual processing deficits associated with the syndrome. Following diagnosis of the syndrome based on typical clinical and electrophysiological criteria, three patients, aged 5, 8, and 10years were referred by epileptologists for neuropsychological evaluation. Neuropsychological findings suggest that the patients had notable impairments on visual memory tasks, especially in comparison with verbal memory. Further, they demonstrated increased difficulty on picture memory suggesting difficulty retaining information from a crowded visual field. Two of the three patients showed weakness in visual processing speed, which may account for weaker retention of complex visual stimuli. Abilities involving attention were normal for all patients, suggesting that inattention is not responsible for these visual deficits. Academically, the patients were weak in numerical operations and spelling, which both rely partially on visual memory and may affect achievement in these areas. Overall, the results suggest that patients with Panayiotopoulos syndrome may have visual processing and visual memory problems that could potentially affect their academic capabilities. Identifying such difficulties may be helpful in creating educational and remedial assistance programs for

    Full Text Available We assessed the neuropsychological test performances of 26 patients (mean age = 41.5 ± 6.1 years; mean years of education = 9.8 ± 1.8; 20 males diagnosed with chronic occupational mercurialism who were former workers at a fluorescent lamp factory. They had been exposed to elemental mercury for an average of 10.2 ± 3.8 years and had been away from this work for 6 ± 4.7 years. Mean urinary mercury concentrations 1 year after cessation of work were 1.8 ± 0.9 µg/g creatinine. Twenty control subjects matched for age, gender, and education (18 males were used for comparison. Neuropsychological assessment included attention, inhibitory control, verbal and visual memory, verbal fluency, manual dexterity, visual-spatial function, executive function, and semantic knowledge tests. The Beck Depression Inventory and the State and Trait Inventory were used to assess depression and anxiety symptoms, respectively. The raw score for the group exposed to mercury indicated slower information processing speed, inferior performance in psychomotor speed, verbal spontaneous recall memory, and manual dexterity of the dominant hand and non-dominant hand (P < 0.05. In addition, the patients showed increased depression and anxiety symptoms (P < 0.001. A statistically significant correlation (Pearson was demonstrable between mean urinary mercury and anxiety trait (r = 0.75, P = 0.03. The neuropsychological performances of the former workers suggest that occupational exposure to elemental mercury has long-term effects on information processing and psychomotor function, with increased depression and anxiety also possibly reflecting the psychosocial context.

    Tourette syndrome (TS) is a neuropsychiatric disorder presenting with motor and/or sonic tics associated with frontostriatal dysfunction. This study provided pilot data of the neuropsychological safety of bilateral thalamic deep brain stimulation (DBS) to treat medication-refractory TS in adults. This study used a repeated-measures design with pretest and 3-month follow-up from start of continuous bilateral DBS. Five male patients underwent DBS surgery for medically refractory TS. Repeated-measures ANOVA was used to evaluate for any change in neuropsychological test scores, employing a false discovery rate. Outcome measures included 14 neuropsychological tests assessing psychomotor speed, attention, memory, language, visuoconstructional, and executive functions, as well as subjective mood ratings of depression and anxiety. Average age was 28.2 years (SD = 7.5) with 12-17 years of education. Participants were disabled by tics, with a tic frequency of 50-80 per minute before surgery. At baseline, subjects' cognitive function was generally average, although mild deficits in sequencing and verbal fluency were present, as were clinically mild obsessive-compulsive symptoms. At 3 months of continuous DBS (5 months after implantation), 3 of 5 participants had clinical reductions in motor and sonic tics. Cognitive scores generally remained stable, but declines of moderate to large effect size (Cohen's d > 0.6) in verbal fluency, visual immediate memory, and reaction time were observed. Fewer symptoms of depression and anxiety, as well as fewer obsessions and compulsions, were reported after 3 months of continuous high-frequency DBS. Bilateral centromedian-parafascicular thalamic DBS for medically refractory TS shows promise for treatment of medically refractory TS without marked neuropsychological morbidity. Symptoms of depression and anxiety improved. © 2014 International Neuromodulation Society.

    Given the disproportionate impact of neurologic disorders such as HIV on racial/ethnic minorities, neuropsychologists are increasingly evaluating individuals of diverse linguistic backgrounds. This study compares the utility of two brief and one comprehensive language measure to account for variation in English neuropsychological performance within a bilingual population. Sixty-two HIV+ English/Spanish bilingual Latino adults completed three language measures in English and Spanish: Self-Reported Language Ability; Verbal Fluency (FAS/PMR); and the Woodcock Munoz Language Survey-Revised (WMLS-R). All participants also completed an English language neuropsychological (NP) battery. It was hypothesized that the comprehensive English/Spanish WMLS-R language dominance index (LDI) would be significantly correlated with NP performance, as well as the best predictor of NP performance over and above the two brief language measures. Contrary to our hypothesis, the WMLS-R LDI was not significantly correlated to NP performance, whereas the easily administered Verbal Fluency and Self-Report LDIs were each correlated with global NP performance and multiple NP domains. After accounting for Verbal Fluency and Self-Report LDI in a multivariate regression predicting NP performance, the WMLS-R LDI did not provide a unique contribution to the model. These findings suggest that the more comprehensive WMLS-R does not improve understanding of the effects of language on NP performance in an HIV+ bilingual Latino population.

    Full Text Available Neuropsychological studies have underlined the significant presence of distinct brain correlates deputed to analyze facial expression of emotion. It was observed that some cerebral circuits were considered as specific for emotional face comprehension as a function of conscious vs. unconscious processing of emotional information. Moreover, the emotional content of faces (i.e. positive vs. negative; more or less arousing may have an effect in activating specific cortical networks. Between the others, recent studies have explained the contribution of hemispheres in comprehending face, as a function of type of emotions (mainly related to the distinction positive vs. negative and of specific tasks (comprehending vs. producing facial expressions. Specifically, ERPs (event-related potentials analysis overview is proposed in order to comprehend how face may be processed by an observer and how he can make face a meaningful construct even in absence of awareness. Finally, brain oscillations is considered in order to explain the synchronization of neural populations in response to emotional faces when a conscious vs. unconscious processing is activated

    Childhood maltreatment is a significant risk factor for a host of psychiatric, developmental, medical, and neurocognitive conditions, often resulting in debilitating and long-term consequences. However, there is no available neuropsychological resource reviewing the literature on the associated neurocognitive deficits in children and adolescents. This review comprehensively examines the 23 prior studies that evaluated the intellectual, language, visual-spatial, memory, motor, and/or attention/executive functions in children and adolescents following an experience of childhood abuse and/or neglect. Neurocognitive impairments were frequently reported. Impairments in executive functions were the most frequent and severe reported impairments, although intelligence, language, visual-spatial skills, and memory are also at serious risk for compromised development following maltreatment. However, specific factors such as abuse/neglect duration, severity, type, and timing during development were all associated with neurocognition. This indicates that these factors are of greater importance than just the presence of abuse/neglect in identifying risk for neurocognitive compromise. Such neurocognitive deficits appear to be a consequence to the known neurobiological and brain development abnormalities of this population, suggesting traumatic stress can be a potential cause of neurodevelopmental disorders. These findings have critical implications for the clinical practice and research involving children following childhood maltreatment and other types of traumatic stress.

    Introduction. Pain is an important nonmotor symptom of Parkinson's disease (PD). Brain areas such as the hippocampus and the prefrontal cortex play an important role in the processing of pain. Since these brain areas are also involved in cognitive functioning, for example, episodic memory and executive functions, respectively, we examined whether a relationship exists between cognitive functioning and spontaneous pain in PD. Methods. Forty-eight patients with PD and 57 controls participated. Cognitive functioning was measured by a comprehensive battery of neuropsychological tests. Both the sensory-discriminative aspect and the motivational-affective aspect of pain were assessed. Multiple linear regression analyses were performed to assess a relation between cognition and pain. Results. Cognition was related to neither the sensory nor the affective aspect of pain in our sample of PD patients. Variance in pain measures was primarily explained by symptoms of depression and anxiety. Discussion. The difference between the affective and the sensory aspect of pain might be due to the neuropathology of PD, which is mainly present in areas processing the affective aspect of pain. Pain treatment might improve when mood is taken into account. We provide several explanations for the lack of an association between pain and cognition. PMID:26881181

    2013-01-01

    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.

    2017-10-01

    The past 50 years have been a period of exciting progress in neuropsychological research on traumatic brain injury (TBI). Neuropsychologists and neuropsychological testing have played a critical role in these advances. This study looks back at three major scientific advances in research on TBI that have been critical in pushing the field forward over the past several decades: The advent of modern neuroimaging; the recognition of the importance of non-injury factors in determining recovery from TBI; and the growth of cognitive rehabilitation. Thanks to these advances, we now have a better understanding of the pathophysiology of TBI and how recovery from the injury is also shaped by pre-injury, comorbid, and contextual factors, and we also have increasing evidence that active interventions, including cognitive rehabilitation, can help to promote better outcomes. The study also peers ahead to discern two important directions that seem destined to influence research on TBI over the next 50 years: the development of large, multi-site observational studies and randomized controlled trials, bolstered by international research consortia and the adoption of common data elements; and attempts to translate research into health care and health policy by the application of rigorous methods drawn from implementation science. Future research shaped by these trends should provide critical evidence regarding the outcomes of TBI and its treatment, and should help to disseminate and implement the knowledge gained from research to the betterment of the quality of life of persons with TBI.

    Traumatic brain injury (TBI) is a serious healthcare problem, and this report is a selective review of recent findings on the epidemiology, pathophysiology and neuropsychological impairments following TBI. Patients who survive moderate-to-severe TBI frequently suffer from a wide range of cognitive deficits and behavioral changes due to diffuse axonal injury. These deficits include slowed information-processing and impaired long-term memory, attention, working memory, executive function, social cognition and self-awareness. Mental fatigue is frequently also associated and can exacerbate the consequences of neuropsychological deficits. Personality and behavioral changes can include combinations of impulsivity and apathy. Even mild TBI raises specific problems: while most patients recover within a few weeks or months, a minority of patients may suffer from long-lasting symptoms (post-concussion syndrome). The pathophysiology of such persistent problems remains a subject of debate, but seems to be due to both injury-related and non-injury-related factors. Copyright © 2017 Elsevier Masson SAS.

    The primary objective of this study was to investigate empirically whether using an interpreter to conduct neuropsychological testing of monolingual Spanish speakers affects test scores. Participants included 40 neurologically normal Spanish speakers with limited English proficiency, aged 18-65 years (M = 39.7, SD = 13.9), who completed the Vocabulary, Similarities, Block Design, and Matrix Reasoning subtests of the Wechsler Adult Intelligence Scale-III in two counterbalanced conditions: with and without an interpreter. Results indicated that interpreter use significantly increased scores on Vocabulary and Similarities. However, scores on Block Design and Matrix Reasoning did not differ depending on whether or not an interpreter was used. In addition the findings suggested a trend toward higher variability in scores when an interpreter was used to administer Vocabulary and Similarities; this trend did not show up for Block Design or Matrix Reasoning. Together the results indicate that interpreter use may significantly affect scores for some tests commonly used in neuropsychological practice, with this influence being greater for verbally mediated tests. Additional research is needed to identify the types of tests that may be most affected as well as the factors that contribute to the effects. In the meantime neuropsychologists are encouraged to avoid interpreter use whenever practically possible, particularly for tests with high demands on interpreter abilities and skills, with tests that have not been appropriately adapted and translated into the patient's target language, and with interpreters who are not trained professionals.

    2008-01-01

    Prognosis for patients with brain metastasis remains poor. Whole brain radiation therapy is the conventional treatment option; it can improve neurological symptoms, prevent and improve tumor associated neurocognitive decline, and prevents death from neurologic causes. In addition to whole brain radiation therapy, stereotactic radiosurgery, neurosurgery and chemotherapy also are used in the management of brain metastases. Radiosensitizers are now currently being investigated as potential treatment options. All of these treatment modalities carry a risk of central nervous system (CNS) toxicity that can lead to neurocognitive impairment in long term survivors. Neuropsychological testing and biomarkers are potential ways of measuring and better understanding CNS toxicity. These tools may help optimize current therapies and develop new treatments for these patients. This article will review the current management of brain metastases, summarize the data on the CNS effects associated with brain metastases and whole brain radiation therapy in these patients, discuss the use of neuropsychological tests as outcome measures in clinical trials evaluating treatments for brain metastases, and give an overview of the potential of biomarker development in brain metastases research

    Epidemiological data demonstrate an association between systemic low-grade inflammation defined as 2- to 3-fold increases in circulating inflammatory mediators and age-related decline in cognitive function. However, it is not known whether small elevations of circulating cytokine levels cause direct effects on human neuropsychological functions. We investigated changes in emotional, cognitive, and inflammatory parameters in an experimental in vivo model of low-grade inflammation. In a double-blind crossover study, 12 healthy young males completed neuropsychological tests before as well as 1.5, 6, and 24 h after an intravenous injection of Escherichia coli endotoxin (0.2 ng/kg) or saline in two experimental sessions. Endotoxin administration had no effect on body temperature, cortisol levels, blood pressure or heart rate, but circulating levels of tumor necrosis factor (TNF) and interleukin (IL)-6 increased 2- and 7-fold, respectively, reaching peak values at 3 h, whereas soluble TNF-receptors and IL-1 receptor antagonist peaked at 4.5 h. The neutrophil count increased and the lymphocyte count declined. In this model, low-dose endotoxemia did not affect cognitive performance significantly but declarative memory performance was inversely correlated with cytokine increases. In conclusion, our findings demonstrate a negative association between circulating IL-6 and memory functions during very low-dose endotoxemia independently of physical stress symptoms, and the hypothalamo-pituitary-adrenal axis.

    We assessed the neuropsychological test performances of 26 patients (mean age = 41.5 +/- 6.1 years; mean years of education = 9.8 +/- 1.8; 20 males) diagnosed with chronic occupational mercurialism who were former workers at a fluorescent lamp factory. They had been exposed to elemental mercury for an average of 10.2 +/- 3.8 years and had been away from this work for 6 +/- 4.7 years. Mean urinary mercury concentrations 1 year after cessation of work were 1.8 +/- 0.9 microg/g creatinine. Twenty control subjects matched for age, gender, and education (18 males) were used for comparison. Neuropsychological assessment included attention, inhibitory control, verbal and visual memory, verbal fluency, manual dexterity, visual-spatial function, executive function, and semantic knowledge tests. The Beck Depression Inventory and the State and Trait Inventory were used to assess depression and anxiety symptoms, respectively. The raw score for the group exposed to mercury indicated slower information processing speed, inferior performance in psychomotor speed, verbal spontaneous recall memory, and manual dexterity of the dominant hand and non-dominant hand (P depression and anxiety symptoms (P depression and anxiety also possibly reflecting the psychosocial context.

    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.

    The neuropsychological outcomes of children who suffered hypoxic episodes following their burns are not completely understood and vary depending on the nature and severity of the episode. A retrospective review of youth that were admitted to this acute burn care facility over the past 20 years was conducted to identify the extent of cognitive and affective difficulties. Thirty-nine children who sustained hypoxic injuries related to their burns were compared with 21 controls that were matched for age, TBSA, and time of injury. Approximately a third of the children who survived from the hypoxia group continued to have long-term cognitive and emotional difficulties. For those who recovered reasonably well, no differences were found from the matched burned controls. These results probably underestimate the true extent of neuropsychological difficulties experienced by these youth given that detailed cognitive testing was not routinely performed. Prospective studies are needed to further characterize the full nature of difficulties and outcomes associated with burn related hypoxic injuries.

    This study explored the neuropsychological performance of patients diagnosed with anorexia nervosa (AN) or bulimia nervosa (BN) compared with healthy controls (HCs). An additional aim was to investigate the effect of several possible mediators on the association between eating disorders (EDs) and cognitive function. Forty patients with AN, 39 patients with BN, and 40 HCs who were comparable in age and education were consecutively recruited to complete a standardized neuropsychological test battery covering the following cognitive domains: verbal learning and memory, visual learning and memory, speed of information processing, visuospatial ability, working memory, executive function, verbal fluency, attention/vigilance, and motor function. The AN group scored significantly below the HCs on eight of the nine measured cognitive domains. The BN group also showed inferior performance on six cognitive domains. After adjusting for possible mediators, the nadir body mass index (lowest lifetime BMI) and depressive symptoms explained all findings in the BN group. Although this adjustment reduced the difference between the AN and HC groups, the AN group still performed worse than the HCs regarding verbal learning and memory, visual learning and memory, visuospatial ability, working memory, and executive functioning. Patients with EDs scored below the HCs on several cognitive function measures, this difference being most pronounced for the AN group. The nadir BMI and depressive symptoms had strong mediating effects. Longitudinal studies are needed to identify the importance of weight restoration and treatment of depressive symptoms in the prevention of a possible cognitive decline. © 2014 Wiley Periodicals, Inc.

    To date, extremely limited research has focused on the ethical aspects of clinical neuropsychology practice in Latin America. The current study aimed to identify the frequency of perceived ethical misconduct in a sample of 465 self-identified neuropsychology professionals from Latin America in order to better guide policies for training and begin to establish standards for practitioners in the region. Frequencies of neuropsychologists who knew another professional engaging in ethical misconduct ranged from 1.1% to 60.4% in the areas of research, clinical care, training, and professional relationships. The most frequently reported perceived misconduct was in the domain of professional training and expertise, with nearly two thirds of participants knowing other professionals who do not possess adequate training to be working as neuropsychologists. The least frequently reported perceived misconduct was in the domain of professional relationships. Nearly one third of participants indicated that they had never received formal training in professional ethics. © The Author 2015. Published by Oxford University Press. All rights reserved.

    2014-09-01

    Pain is an experience that none of us would like to have but that each one of us is destined to experience in our lives. Despite its pervasiveness, the experience of pain remains problematic and complex in its depth. Pain is a multidimensional experience that involves nociception as well as emotional and cognitive aspects that can modulate its perception. Following a brief discussion of the neurobiological mechanisms underlying pain, the purpose of this review is to discuss the main psychological, neuropsychological, cultural, and existential aspects which are the basis of diverse forms of pain, like the pain of separation from caregivers or from ourselves (e.g., connected to the thought of our death), the suffering that we experience observing other people's pain, the pain of change and the existential pain connected to the temporal dimension of the mind. Finally, after a discussion of how the mind is able to not only create but also alleviate the pain, through mechanisms such as the expectation of the treatment and the hope of healing, we conclude by discussing neuropsychological research data and the attitude promoted by mindfulness meditation in relation to the pain. An attitude in which, instead to avoid and reject the pain, one learns to face mindfully the experience of pain.

  2. Cognitive and neuropsychological outcomes: more than IQ scores.

    Improved survival in preterm infants has broadened interest in cognitive and neuropsychological outcomes. The incidence of major disabilities (moderate/severe mental retardation, neurosensory disorders, epilepsy, cerebral palsy) has remained consistent, but high prevalence/low severity dysfunctions (learning disabilities, ADHD, borderline mental retardation, specific neuropsychological deficits, behavioral disorders) have increased. The follow-up literature contains methodologic problems that make generalizations regarding outcome difficult, and these are discussed. Although mean IQs of former VLBW infants generally are in the low average range and are 3-9 points below normal birth weight peers, these scores mask subtle deficits in: visual-motor and visual-perceptual abilities, complex language functions, academics (reading, mathematics, spelling and writing), and attentional skills. There is an increased incidence of non-verbal learning disabilities, need for special educational assistance, and behavioral disorders in children born prematurely. Males have more problems, and there is a trend for worsening outcome over time, due to emergence of more subtle deficits in response to increased performance demands. In addition to IQ and achievement testing in follow-up, there should be evaluation of executive functions and attention, language, sensorimotor functions, visuospatial processes, memory and learning, and behavioral adjustment.

    The public is gradually becoming aware of specific learning disabilities (SLDs), which are very often the cause of academic difficulties. The aim of the study was to assess the SLDs in the clinic population at the Child and Adolescent Psychiatry Clinic at the Postgraduate Institute of Medical Education and Research (PGIMER), Chandigarh using the National Institute of Mental Health and Neurosciences SLD index and subsequently to assess the children's neuropsychological functions using a battery of tests. Thirty-five children in the age range of 7-14 years (both boys and girls) were recruited as the cohort, diagnosed clinically and assessed using the battery of tests for SLDs and neuropsychological tests consisting of the PGIMER memory scale for children, the Wisconsin card sorting test, the Bender visuo-motor gestalt test and Malin's intelligence scale for Indian children. The study revealed deficits in language and writing skills and impairments in specific areas of memory, executive functions and perceptuo-motor tasks. Identification of SLDs is useful in drawing up a treatment plan specific for a particular child.

    The polymorphism at codon 129 of the prion protein gene (PRNP) and the PrPSc types 1 and 2 belong to a molecular classification of sporadic Creutzfeldt-Jakob disease (sCJD) that correlates well with the clinical and neuropathological phenotype of sCJD. The aim of the study was to perform the first detailed evaluation of neuropsychological deficits in a large group of definite sCJD patients with known molecular subtype. We analyzed neuropsychological symptoms in a cohort of 248 sCJD patients with known M129 V polymorphism of PRNP and prion protein type. Neuropsychological symptoms were very frequent in our patients (96%) and occurred as early as in the first third of the disease course. Besides amnesia and impaired attention (89% each), frontal lobe syndrome (75%), aphasia (63%), and apraxia (57%) were the most common neuropsychological deficits. There was no statistically significant difference with regard to frequency of neuropsychological symptoms between the subtypes. In MV2 and VV2 patients, the onset of neuropsychological symptoms was significantly later than in all other subtypes. We provide the first detailed analysis of neuropsychological symptoms in a large group of sCJD patients with known M129 V genotype and prion protein type. We suggest that the rate of progression of neuropsychological symptoms is subtype-specific. These data may improve the diagnosis in atypical sCJD subtypes.

    The impact of heading on neuropsychological performance is a subject of controversy. In this experimental study, a controlled group design was used to investigate the possible effects of a short heading training session on neuropsychological performance. Ninety-one participants matched by age, sex, and intelligence were assigned to one of the following groups: A heading-training group, a placebo control group, and a waiting control group. All participants completed a neuropsychological test battery for attention and working memory (D2 Test, Benton Visual Retention Test, Paced Auditory Serial Addition Task Test). After 1 week, they received heading training, football (e.g., soccer) training without heading, or no training. Immediately after this training, the neuropsychological tests were conducted again. There was no neuropsychological deficit which could only be attributed to the heading training. However, within the heading group, women complained more about headache than men.

    Full Text Available Multiple sclerosis (MS is a progressively disabling neurological disease which symptoms affect sensory, motor and psychological functioning. Several clinical neurological and psychological variables influence the neuropsychological profile in MS, which is extremely heterogeneous. The main objective of the present study was to investigate if it is possible to statistically stratify control subjects and MS patients from neurological, socio-demographic and neuropsychological dimensions. With this purpose we applied cluster analysis procedures to five neuropsychological instruments selected according to diagnostic accuracy from a pool of 9 neuropsychological tests. The sample was composed of 45 healthy controls and 35 MS patients with similar socio-demographic characteristics. The results indicated an ideal solution with 4 different clusters according to two dimensions: "cognitive" and "psychosocial" functioning, which represent independent but non-disjunctive aspects of neuropsychological functioning in MS.

    Though some neuropsychological groups have proposed criteria and suggestions for clinical report writing there has never been professional consensus or accepted published guidelines on how to write reports. Given the paucity of guidelines and the evolving practice climate, we sought to survey neuropsychologists and referral source stakeholders to understand current report writing practices. The data were collected in two SurveyMonkey surveys via professional list servs, email, and LinkedIn clinical interest groups. Results of the survey indicate many neuropsychologists spend multiple hours writing reports that they believe will not be read completely by stakeholders. A striking 73% of referral sources reported slow turnaround time of neuropsychological reports negatively affected their patient care. Referral sources reported they value the diagnosis/impression and recommendations sections the most; in contrast, they did not find the history, behavioral observations, emotional functioning, or descriptions of cognitive domains sections as useful. The survey findings highlight the disjuncture between what neuropsychologists typically do in their practice of report writing versus what they believe is useful for patients and referral sources. The survey also highlights differences between writing practices of neuropsychologists and what referral sources identify as the most valuable aspects of reports to assist them in caring for their patients.

    We clinically investigated 34 patients with obstructive colorectal cancer who underwent placement of a colonic stent as a bridge to surgery(BTS), focusing on endoscopic findings after stent placement.Twenty -nine patients(85.3%)underwent colonoscopy after stent placement, and the entire large intestine could be observed in 28(96.6%).Coexisting lesions were observed in 22(78.6%)of these 28 patients.The lesions comprised adenomatous polyps in 17 patients(60.7%), synchronous colon cancers in 5 patients(17.9%), and obstructive colitis in 3 patients(10.7%), with some overlapping cases.All patients with multiple cancers underwent one-stage surgery, and all lesions were excised at the same time.Colonoscopy after colonic stent placement is important for preoperative diagnosis of coexisting lesions and planning the extent of resection. These considerations support the utility of colonic stenting for BTS.

    2017-01-01

    Body dysmorphic disorder (BDD) is characterized by a preoccupation with a perceived defect or flaw in physical appearance that is not observable or appears slight to others. It leads to severe distress and functional impairment. Cognitive-behavioural and neurobiological similarities to obsessive compulsive disorder (OCD) have led to its newly conceived classification as an obsessive compulsive related disorder (OCRD). In the process of investigating the neurobiology of BDD, neuroimaging and neuropsychological studies have been conducted. This review presents the most recent research findings and their connection with BDD clinical features. Imaging studies have shown increased total white matter volume and caudate volume asymmetry in BDD patients. These findings are consistent with the striatal topography model of OCRDs. Other studies have showed perfusion deficits in bilateral anterior-medial temporal and occipital regions and asymmetric perfusion in parietal lobes. In addition, correlation between symptom severity and left inferior frontal gyrus volume reflects the degree of detailed, analytic encoding that occurs on day-to-day basis when viewing others and themselves, and that likely underlies their symptoms. Finally, positive correlation between right amygdala volume and symptom severity signifies pathological fear circuitry engagement, hypervigilance and heightened sensitivity to social situations. Neuropsychological studies of BDD reveal deficits in strategic organization, learning and free recall after short and long delays. Executive function deficits are related to spatial working memory and subsequent thinking speed as well as impaired higher level planning ability. BDD patients' organizational strategies tend to focus on detail rather than on larger, global clustering features. They are characterized by abnormal visual processing of both details and global elements, inaccurate processing of global elements and reduced flexibility in switching visual

    2017-09-01

    Full Text Available Prader-Willi Syndrome (PWS is a complex neurodevelopmental disorder caused by genetic anomalies that presents itself with a characteristic neurobehavioral phenotype. The aim of this project was to analyze interventions of neuropsychological rehabilitation that exist in PWS and to achieve it, a systematic search was done, resulting in a total of 14 articles with interventions for behavioral, cognitive and familial phenotypical characteristics. The studies were analyzed according to the focus of the intervention, models, specific procedures and results. Most studies used a compensation model and almost all applied behavioral modification techniques. The results suggest that techniques that use differential reinforcement and a more active involvement of the person with PWS and their family during intervention, are more successful.

    Full Text Available Nutritional deficiency can cause, mainly in chronic alcoholic subjects, the Wernicke encephalopathy and its chronic neurological sequela, the Wernicke-Korsakoff syndrome (WKS. Long-term chronic ethanol abuse results in hippocampal and cortical cell loss. Thiamine deficiency also alters principally hippocampal- and frontal cortical-dependent neurochemistry; moreover in WKS patients, important pathological damage to the diencephalon can occur. In fact, the amnesic syndrome typical for WKS is mainly due to the damage in the diencephalic-hippocampal circuitry, including thalamic nuclei and mammillary bodies. The loss of cholinergic cells in the basal forebrain region results in decreased cholinergic input to the hippocampus and the cortex and reduced choline acetyltransferase and acetylcholinesterase activities and function, as well as in acetylcholine receptor downregulation within these brain regions. In this narrative review, we will focus on the neurochemical, neuroanatomical, and neuropsychological studies shedding light on the effects of thiamine deficiency in experimental models and in humans.

    1991-01-01

    It has been postulated that deficits in certain areas of cognitive functioning among children of alcoholics may contribute to their increased risk for developing alcoholism and other substance abuse disorders. In this chapter, the recent evidence for this hypothesis is critically reviewed. Studies citing differences in cognitive functioning between persons at high risk versus those at low risk for alcoholism are presented as well as those studies that have failed to demonstrate differences in cognitive abilities. On balance, the evidence in support of variations in cognitive abilities at risk factors for the development of alcoholism is not strong. The equivocal nature of the literature may be due to a variety of issues related to the design of studies examining risk factors for alcoholism, to the variability of definitions of family history positive used, to the failure to adequately control potentially confounding subject variables, and to the improper analysis of data. Recommendations are made for future studies examining neuropsychological functioning in "at risk" samples.

  3. Neuropsychological consequences of chronic drug use: relevance to treatment approaches

    Directory of Open Access Journals (Sweden)

    Jean Lud eCadet

    2016-01-01

    Full Text Available Heavy use of drugs impacts of the daily activities of individuals in these activities. Several groups of investigators have indeed documented changes in cognitive performance by individuals who have a long history of chronic drug use. In the case of marijuana, a wealth of information suggests that heavy long-term use of the drug may have neurobehavioral consequences in some individuals. In humans, heavy cocaine use is accompanied by neuropathological changes that might serve as substrates for cognitive dysfunctions. Similarly, methamphetamine users suffer from cognitive abnormalities that may be consequent to alterations in structures and functions. Here, we detail the evidence for these neuropsychological consequences. The review suggests that improving the care of our patients will necessarily depend on the better characterization of drug-induced cognitive phenotypes because they might inform the development of better pharmacological and behavioral interventions, with the goal of improving cognitive functions in these subsets of drug users.

    This paper provides insight into the cognitive and neural mechanisms of personal semantic memory, knowledge that is specific and unique to individuals, by reviewing neuropsychological research on stable amnesia secondary to medial temporal lobe damage. The results reveal that personal semantic memory does not depend on a unitary set of cognitive and neural mechanisms. Findings show that autobiographical fact knowledge reflects an experience-near type of personal semantic memory that relies on the medial temporal lobe for retrieval, albeit less so than personal episodic memory. Additional evidence demonstrates that new autobiographical fact learning likely relies on the medial temporal lobe, but the extent to which remains unclear. Other findings show that retrieval of personal traits/roles and new learning of personal traits/roles and thoughts/beliefs are independent of the medial temporal lobe and thus may represent highly conceptual types of personal semantic memory that are stored in the neocortex.

    The development of robust neuropsychological measures of social and affective function-which link critical dimensions of mental health to their underlying neural circuitry-could be a key step in achieving a more pathophysiologically-based approach to psychiatric medicine. In this article, we summarize research indicating that self-reflection (the inward attention to personal thoughts, memories, feelings, and actions) may be a useful model for developing such a paradigm, as there is evidence that self-reflection is (1) measurable with self-report scales and performance-based tests, (2) linked to the activity of a specific neural circuit, and (3) dimensionally related to mental health and various forms of psychopathology.

    This essay discusses the intellectual developments in psychology, linguistics, and behavioral neurology that shaped Oscar Marin's approach to disorders of high cortical function. As Chief of Neurology at Baltimore City Hospitals in the 1970s, Dr Marin teamed with biopsychologist Eleanor Saffran and the author in seminal studies of acquired language disorders (aphasia) centering on core processes of syntax and semantics, and rejecting premature reductionism. The philosophical and methodological principles that motivated these studies are traced through the author's personal recollections and the published writings of the Marin lab. These principles came to be associated with the cognitive neuropsychology school of research and have important linkages to contemporary work in the neuroscience of aphasia and related cognitive disorders.

    Full Text Available BACKGROUND: Recent studies have reported that patients with end-stage heart disease can have cognitive deficits ranging from mild to severe. Little is known, however, about the relationship between cognitive performance, neurophysiological characteristics and relevant clinical and instrumental indexes for an extensive evaluation of patients with heart failure, such as: left ventricular ejection fraction (LVEF and other haemodynamic measures, maximum oxygen uptake during cardiopulmonary exercise testing, comorbidities, major cardiovascular risk factors and disease duration. Our purpose was to outline the cognitive profiles of end-stage heart disease patients in order to identify the cognitive deficits that could compromise the quality of life and the therapeutic adherence in end-stage heart disease patients, and to identify the variables associated with an increased risk of cognitive deficits in these patients. METHODS: 207 patients with end-stage cardiac disease, candidates for heart transplant, were assessed by complete neuropsychological evaluation and by electroencephalographic recording with EEG spectral analysis. RESULTS: Pathological scores in one or more of the cognitive tests were obtained by 86% of the patients, while 36% performed within the impaired range on five or more tests, indicating poor performance across a broad range of cognitive domains. The executive functions were the cognitive domain most impaired (70%. Poor performances were not related to the aetiology of heart disease, but rather to cerebral dysfunction secondary to haemodynamic impairment and to comorbidities. CONCLUSIONS: Severe heart failure induces significant neurophysiological and neuropsychological alterations, which may produce an impairment of cognitive functioning and possibly compromise the quality of life of patients and the therapeutic adherence.

    Several scholars have recommended using data from neuropsychological tests to develop interventions for reading and mathematics. The current study examined the effects of using neuropsychological data within the intervention process with meta-analytic procedures. A total of 1,126 articles were found from an electronic search and compared to inclusion criteria, which resulted in 37 articles that were included in the current study. Each article was coded based on how the data were used (screening-86% or designing interventions-14%), size of the group for which interventions were delivered (small group-45%, individual students-45%, or entire classroom-10%), and type of data collected (cognitive functions-24%, reading fluency-33%, phonemic/phonological awareness-35%, or mixed-8%). A corrected Hedges' g was computed for every study and reported for variables of interest. A Fail-safe N was also computed to determine how many studies with a zero effect would have to be found to change the conclusions. The data resulted in a small effect (g = 0.17) for measures of cognitive functioning, but moderate effects of g = 0.43 and g = 0.48 for measures of reading fluency and phonemic/phonological awareness. There were few studies that examined measures of cognitive functioning within the intervention process. Taken together with previous research, the data do not support the use of cognitive measures to develop interventions but instead favor more direct measures of academic skills (e.g., reading fluency) in a skill-by-treatment interaction. Implications for practice and future research are discussed. (c) 2016 APA, all rights reserved).

    Herpes simplex virus (HSV) is the most common causative pathogen of nonepidemic encephalitis in Japan. The mortality rate is approximately 30% and surviving patients often have severe sequelae such as amnestic syndrome. Between 1979 and 1992, 13 patients with herpes simplex encephalitis (HSE) were admitted to our Department. Diagnosis was based on the neurological symptoms and signs, the findings on EEG, CT and MRI, and the results of serological examination including ELISA for HSV type 1. Neuropsychological tests were performed over a period of approximatly 2 years in seven of 13 patients. The results of the tests disclosed memory impairments as follows. Namely, immediate recall was well preserved, but disturbance of recent memory and retrograde amnesia over 20 years were observed. The neuropsychological features more closely resembled those of amnestic syndrome than those of Korsakoff syndrome. The amnesia in HSE patients was characterized in the finding that it was prone to recover more gradually as compared with that following head trauma or surgical brain resection. CT scan was performed in 13 patients during the acute and convalescent stages. The low density areas were found in the temporal lobes in 60% of the patients. MRI were obtained during the convalescent stage in ten of 13 patients. In seven of the ten patients, abnormal signals were distributed uni- or bilaterally to the temporal lobe, insular and limbic system such as the hippocampus and amygdala. In the remaining three patients, the abnormal signals were localized in both hippocampi and amygdalae in one patient and only in the brain stem in another. In the last case, the MRI was normal. The findings that signal intensity on MRI showing the lesion in the temporal lobe spread continuously to the opposite limbic area or occipital lobe strongly suggested the spreading of HSV through neural fiber connections in HSE.

    Full Text Available Neurobiological factors had been shown to play an important role in the emergence of obsessive-compulsive disorder by the information obtained from the methods developed over the years. According to the neuropsychological perspective, the defects had been detected mainly in executive functions, in attention, memory, visual-spatial functions; and abnormalities had been described in the frontal lobe, cingulate cortex, basal ganglia, and thalamus regions of the patients with obsessive-compulsive disorder. The main and the most repeated abnormalities in patients with obsessive-compulsive disorder are dysfunctions in executive function and visual memory. Dysfunctions of the inhibitory processes associated with the dominant frontal area lead to an insufficiency on the inhibition of verbal functions. Excessive activation of the orbitofrontal cortex that mediate the behavioral response suppression function in obsessive-compulsive disorder demonstrated by functional imaging techniques. Repeated-resistant behaviors (eg: compulsions are composed by the deteriorations of the inhibitions of motor or cognitive programs in basal ganglions provided through cycles of frontal lobe. The findings of clinical observations in patients with obsessive-compulsive disorder could be considered as a reflection of excessive work in 'error detection system' which is the cause of the thoughts that something goes wrong and efforts to achieve perfection. As neurobiological, this finding is observed as excessive activity in orbitofrontal cortex and anterior cingulate cortex representing the ability of humans to provide and detect errors. It is is expected to develop the vehicles that are more sensitive to the characteristics of cognitive deficits in obsessive-compulsive disorder. In addition to the neuropsychological tests, using electrophysiological and advanced functional imaging techniques will put forward a better underlying the physiopathology of this disorder in order to

    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 <.006). Compared with HVs, SPD patients demonstrate modest cognitive 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.

    Full Text Available Introduction: Multiple sclerosis (MS is a progressive demyelinating and degenerative neurological disease. The degree of disability increases along with pathological damage, especially in cases with comorbidity. Methodology: The objective of this study was to analyze the influence of MS alone and with comorbidity on some neuropsychological patterns. Individual quality of life of 80 MS patients at a mean age of 49 years, 56 females and 24 males, was examined by means of Multiple Sclerosis Quality of Life-54 Questionnaire (MSQOL-54 in 2002-2015. Forty patients presented with MS alone and 40 with MS and comorbidity. The frequency of troubles of mental concentration/thinking, fixation of attention, and memory as well as of difficulty at work and other activities were examined. Results: Statistically significant differences were observed between patients with MS alone and those with MS and comorbidity concerning troubles of mental concentration/thinking (t=4.822; p<0.0001, and of memory (t=4.020; p<0.0001. Gender correlated negatively with troubles of memory (R=-0.343; r<0.05, while EDSS scores did with troubles of memory (R=-0.346; p<0.05 and with troubles of attention (R=-0.330; p<0.05. The accompanying diseases additionally worsened the components of health-related quality of life. Conclusions: Common comorbidity in MS patients requires careful clinical examinations and proper management in order to reduce the neuropsychological burden and assure a better individual quality of life for the patient.

    2015-09-01

    Full Text Available This study was designed to find the clinical, neuropsychologic, EEG and TMS (Transcranial Magnetic Stimulation characteristics of patients with treatment resistant Juvenile Myoclonic Epilepsy (JME. JME diagnosis was according to the criteria defined by Classification and Terminology Commission of the International League Against Epilepsy. For the purpose of this study, ‘treatment resistance’ was defined as having two or more generalized tonic - clonic sei zures (GTCS or disabling myoclonus resulting in falls, while on optimal dose of a first - line anti - epileptic drug for JME, with proper compliance. All the patients with JME presenting during the study period underwent detailed clinical and EEG evaluation. Hospital Anxiety and Depression score (HADS was used to screen for anxiety and depression. Single and paired pulse (TMS parameters were used to measure cortical excitability. We identified 190 patients with JME during the study period, of which 30 (15.8% were diagnosed as having treatment resistance JME. Patients with drug resistant JME were found to have statistically significant markers in the form of - later age of onset of myoclonic jerks, absence of typical early morning myoclonia, higher scores for depression and anxiety, low IQ scores and persistent EEG abnormalities while on treatment. Frequency of GTCS showed inverse correlation with IQ scores and direct correlation to the anxiety/depression scores. These patients also had paradoxically decreased cortical excitability, probably related to the high antiepileptic drug doses they were taking. We conclude that treatment resistance in JME is not very rare and that such patients form a distinct subtype with certain atypical clinical and electrophysiolog ical characteristics, with a higher risk of developing anxiety and depression

    Studies suggest that higher cognitive functions could precipitate seizures in juvenile myoclonic epilepsy (JME). The present study aimed to analyze the effects of higher mental activity on epileptiform discharges and seizures in patients with JME and compare them to those of habitual methods of activation. Seventy-six patients with JME (41 female) underwent a video-EEG (electroencephalography) neuropsychologic protocol (VNPP) and habitual methods of activation for 4-6 h. Twenty-nine of the 76 (38.2%) presented provocative effect, and inhibition was seen in 28 of 31 (90.3%). A mixed effect was observed in 11 (35.5%), and 30 patients (39.5%) suffered no effect of VNPP. Action-programming tasks were more effective than thinking in provoking epileptiform discharges (23.7% and 11.0% of patients, respectively, p = 0.03). Inhibitory effect was observed equally in the various categories of tasks, except in mental calculation, which had a higher inhibitory rate. Habitual methods of activation were more effective than VNPP in provoking discharges. Anxiety disorders were diagnosed in 24 of 58 patients (41.4%); anxious patients had greater discharge indexes and no significant inhibitory effect on VNPP. Praxis exerted the most remarkable provocative effect, in accordance with the motor circuitry hyperexcitability hypothesis in JME. Inhibitory effect, which had no such task specificity, might be mediated by a widespread cortical-thalamic pathway, possibly involving the parietal cortex. The frequent inhibitory effect found under cortical activation conditions, influenced by the presence of anxiety, supports nonpharmacologic therapeutic interventions in JME.

    Rett syndrome (RS) is a childhood neurodevelopmental disorder characterized by a primary disturbance in neuronal development. Neurological abnormalities in RS are reflected in several behavioral and cognitive impairments such as stereotypies, loss of speech and hand skills, gait apraxia, irregular breathing with hyperventilation while awake, and frequent seizures. Cognitive training can enhance both neuropsychological and neurophysiological parameters. The aim of this study was to investigate whether behaviors and brain activity were modified by training in RS. The modifications were assessed in two phases: (a) after a short-term training (STT) session, i.e., after 30 min of training and (b) after long-term training (LTT), i.e., after 5 days of training. Thirty-four girls with RS were divided into two groups: a training group (21 girls) who underwent the LTT and a control group (13 girls) that did not undergo LTT. The gaze and quantitative EEG (QEEG) data were recorded during the administration of the tasks. A gold-standard eye-tracker and a wearable EEG equipment were used. Results suggest that the participants in the STT task showed a habituation effect, decreased beta activity and increased right asymmetry. The participants in the LTT task looked faster and longer at the target, and show increased beta activity and decreased theta activity, while a leftward asymmetry was re-established. The overall result of this study indicates a positive effect of long-term cognitive training on brain and behavioral parameters in subject with RS. Copyright © 2016 Elsevier Ltd.

    Limited information is currently available about performance of Spanish-speaking children on different neuropsychological tests. This study was designed to (a) analyze the effects of age and sex on different neuropsychological test scores of a randomly selected sample of Spanish-speaking children, (b) analyze the value of neuropsychological test scores for predicting school performance, and (c) describe the neuropsychological profile of Spanish-speaking children with learning disabilities (LD). Two hundred ninety (141 boys, 149 girls) 6- to 11-year-old children were selected from a school in Bogotá, Colombia. Three age groups were distinguished: 6- to 7-, 8- to 9-, and 10- to 11-year-olds. Performance was measured utilizing the following neuropsychological tests: Seashore Rhythm Test, Finger Tapping Test (FTT), Grooved Pegboard Test, Children's Category Test (CCT), California Verbal Learning Test-Children's Version (CVLT-C), Benton Visual Retention Test (BVRT), and Bateria Woodcock Psicoeducativa en Español (Woodcock, 1982). Normative scores were calculated. Age effect was significant for most of the test scores. A significant sex effect was observed for 3 test scores. Intercorrelations were performed between neuropsychological test scores and academic areas (science, mathematics, Spanish, social studies, and music). In a post hoc analysis, children presenting very low scores on the reading, writing, and arithmetic achievement scales of the Woodcock battery were identified in the sample, and their neuropsychological test scores were compared with a matched normal group. Finally, a comparison was made between Colombian and American norms.

    Bodin and Grote convey their opinion that the field of clinical neuropsychology would be best served by a match system for recruitment into postdoctoral training. We critically review their arguments and offer an alternative point of view. Our view considers the current state of the match system in neuropsychology, incorporates comparisons with other disciplines that rely on a match system, and addresses the role of postdoctoral training and the specialization that takes shape at this level. We make recommendations aimed at promoting greater unity among postdoctoral training programs with the goal of focusing leadership efforts on advancing our shared mission of providing the highest quality training in clinical neuropsychology.

    Objective: The aim of the present study was to compare female sexual function between women who underwent conventional abdominal or laparoscopic hysterectomy. Materials and Methods: Seventy-seven women who were scheduled to undergo hysterectomy without oophorectomy for benign gynecologic conditions were included in the study. The women were assigned to laparoscopic or open abdominal hysterectomy according to the surgeons preference. Women with endometriosis and symptomatic prolapsus were excluded. Female sexual function scores were obtained before and six months after the operation from each participant by using validated questionnaires. Results: Pre- and postoperative scores of three different quationnaires were found as comparable in the group that underwent laparoscopic hysterectomy (p>0.05). Scores were also found as comparable in the group that underwent laparotomic hysterectomy (p>0.05). Pre- and postoperative values were compared between the two groups and revealed similar results with regard to all three scores (p>0.05). Conclusion: Our data showed comparable pre- and the postoperative scores for the two different hysterectomy techniques. The two groups were also found to have similar pre- and postoperative score values. PMID:28913149

    The objective of this study was to determine the association of vaginal cuff length (VCL) with vaginal and pelvic recurrence rates in patients with cervical cancer who underwent radical hysterectomies. The clinicopathologic characteristics were collected from the medical records of 280 patients with cervical cancer who underwent radical hysterectomies. The association of VCL with 3-year vaginal and pelvic recurrence rates was determined using a Z-test. The association of VCL with other clinicopathologic characteristics was also determined. The VCL was not associated with 3-year vaginal and pelvic recurrence rates. The 3-year vaginal recurrence rate was 0%-2% and the 3-year pelvic recurrence rate was 7%-8%, independent of VCL. The VCL and the age of patients had an inverse relationship. However, the VCL was not associated with histologic type, FIGO stage, clinical tumor size, tumor size in the surgical specimen, depth of invasion, lymphovascular space invasion, parametrial involvement, lymph node involvement, and adjuvant therapy. One-hundred ninety of 280 patients (68%) underwent adjuvant therapies following radical hysterectomies. Although it is limited by the high rate of adjuvant therapy, the current study suggested that the VCL following radical hysterectomy in patients with cervical cancer was not associated with vaginal and pelvic recurrence rates.

    Neuropathology and surveys of retired National Football League (NFL) players suggest that chronic brain damage is a frequent result of a career in football. There is limited information on the neurological statuses of living retired players. This study aimed to fill the gap in knowledge by conducting in-depth neurological examinations of 30- to 60-year-old retired NFL players. In-depth neurological examinations of 30- to 60-year-old retired players are unlikely to detect objective clinical abnormalities in the majority of subjects. A day-long medical examination was conducted on 45 retired NFL players, including state-of-the-art magnetic resonance imaging (MRI; susceptibility weighted imaging [SWI], diffusion tensor imaging [DTI]), comprehensive neuropsychological and neurological examinations, interviews, blood tests, and APOE (apolipoprotein E) genotyping. Level 3. Participants' histories focused on neurological and depression symptoms, exposure to football, and other factors that could affect brain function. The neurological examination included Mini-Mental State Examination (MMSE) evaluation of cognitive function and a comprehensive search for signs of dysarthria, pyramidal system dysfunction, extrapyramidal system dysfunction, and cerebellar dysfunction. The Beck Depression Inventory (BDI) and Patient Health Questionnaire (PHQ) measured depression. Neuropsychological tests included pen-and-paper and ImPACT evaluation of cognitive function. Anatomical examination SWI and DTI MRI searched for brain injuries. The results were statistically analyzed for associations with markers of exposure to football and related factors, such as body mass index (BMI), ethanol use, and APOE4 status. The retired players' ages averaged 45.6 ± 8.9 years (range, 30-60 years), and they had 6.8 ± 3.2 years (maximum, 14 years) of NFL play. They reported 6.9 ± 6.2 concussions (maximum, 25) in the NFL. The majority of retired players had normal clinical mental status and central

METHODS: One hundred and thirty-one consecutive referred elderly patients (37 clinical-controls, 41 with amnestic MCI and 53 with possible/probable AD were diagnosed with a comprehensive (full neuropsychological battery, MRI and clinical data. All of the results were blindly coded and evaluated latter with a subset of the tests to reclassify the subjects as MCI, dementia or clinical-control. Agreement rates between both batteries were calculated. We also used ROC curves to establish the sensitivity and specificity of the brief battery for discriminating (i clinical-control individuals from a group dementia and MCI patients; (ii individuals with dementia from individuals without dementia; (iii clinical-control individuals from a group of MCI. We compared performance of the three groups on all full battery tasks. RESULTS: All neuropsychological tests showed differences between clinical-control and dementia groups. The comparison between MCI and the other groups mainly showed memory differences. Agreement between brief and full batteries was substantial (kappa = 0.805. Analyses with ROC curves showed good sensitivity and specificity to discriminate non-demented (clinical control plus MCI groups and AD group and also to discriminate clinical-control individuals from individuals with cognitive decline (MCI plus AD group. However, sensitivity and specificity significantly decreased when brief battery was tested to discriminate only normal and MCI diagnosis. DISCUSSION: The use of a brief battery might not be indicated to discriminate MCI and clinical-control individuals, but its use might be adequate to discriminate less specific groups (demented versus non-demented and pathological [dementia and MCI] and non-pathological [clinical-control] groups.

    Deep brain stimulation (DBS) is an effective treatment for patients with advanced Parkinson's disease (PD) and motor symptom complications. Recently, attention has been focused on whether offering DBS earlier in the course of PD is beneficial. The purpose of this study was to determine the effects of DBS on neuropsychological functioning in subjects with early stage PD. Thirty subjects with early PD (Hoehn & Yahr Stage II off medication) were randomized to optimal drug therapy (ODT) (n = 15) or bilateral subthalamic nucleus (STN) DBS+ODT (n = 15) after completing an expanded informed consent process specially designed for the study and administered by a medical ethicist and the study team. Comprehensive neuropsychological testing was completed in the treatment-withdrawn state at baseline and at 12 month and 24 month follow-ups. Two serious adverse events occurred in the DBS+ODT group. One subject experienced a stroke and another developed infected hardware that contributed to specific declines in cognitive functioning. However, compared to the ODT group, the remaining subjects in the DBS+ODT group exhibited modest reductions on a few measures of attention, executive function, and word fluency at 12 months. These differences were largely diminished at 24 months, especially when those with the adverse events were excluded. The results of this trial provide novel data regarding the effects of DBS on cognitive function in early PD. We believe that the findings and insights from this trial can help guide the safety analysis and risk-benefit evaluations in future discussions of DBS in early stage PD.

    Full Text Available Theta burst stimulation (TBS protocols hold high promise in neuropsychological rehabilitation. Nevertheless, their ability to either decrease (continuous, cTBS or increase (intermittent, iTBS cortical excitability in areas other than the primary motor cortex, and their consistency modulating human behaviors with clinically relevant tasks remain to be fully established. The behavioral effects of TBS over the dorsolateral prefrontal cortex (dlPFC are particularly interesting given its involvement in working memory (WM and executive functions (EF, often impaired following frontal brain damage. We aimed to explore the ability of cTBS and iTBS to modulate WM and EF in healthy individuals, assessed with clinical neuropsychological tests (Digits Backward, 3-back task, Stroop Test, and Tower of Hanoi. To this end, 36 participants were assessed using the four tests 1 week prior to stimulation and immediately following a single session of either cTBS, iTBS, or sham TBS, delivered to the left dlPFC. No significant differences were found across stimulation conditions in any of the clinical tasks. Nonetheless, in some of them, active stimulation induced significant pre/post performance modulations, which were not found for the sham condition. More specifically, sham stimulation yielded improvements in the 3-back task and the Color, Color-Word, and Interference Score of the Stroop Test, an effect likely caused by task practice. Both, iTBS and cTBS, produced improvements in Digits Backward and impairments in 3-back task accuracy. Moreover, iTBS increased Interference Score in the Stroop Test in spite of the improved word reading and impaired color naming, whereas cTBS decreased the time required to complete the Tower of Hanoi. Differing from TBS outcomes reported for cortico-spinal measures on the primary motor cortex, our analyses did not reveal any of the expected performance differences across stimulation protocols. However, if one considers independently

    Full Text Available Punding, one of dopamine replacement treatment related complications, refers to aimless and stereotyped behaviors. To identify possible neural correlates of punding behavior in patients with Parkinson's disease (PD, we investigated the patterns of cognitive profiles and cortical thinning.Of the 186 subjects with PD screened during the study period, we prospectively enrolled 10 PD patients with punding and 43 without punding on the basis of a structured interview. We performed comprehensive neuropsychological tests and voxel-based and regions-of-interest (ROIs-based cortical thickness analysis between PD patients with and without punding.The prevalence of punding in patients with PD was 5.4%. Punding behaviors were closely related to previous occupations or hobbies and showed a temporal relationship to changes of levodopa-equivalent dose (LED. Significant predisposing factors were a long duration of PD and intake of medications of PD, high total daily LED, dyskinesia, and impulse control disorder. Punding severity was correlated with LED (p = 0.029. The neurocognitive assessment revealed that PD patients with punding showed more severe cognitive deficits in the color Stroop task than did those without punding (p = 0.022. Voxel-based analysis showed that PD-punders had significant cortical thinning in the dorsolateral prefrontal area relative to controls. Additionally, ROI-based analysis revealed that cortical thinning in PD-punders relative to PD-nonpunders was localized in the prefrontal cortices, extending into orbitofrontal area.We demonstrated that PD patients with punding performed poorly on cognitive tasks in frontal executive functions and showed severe cortical thinning in the dorsolateral prefrontal and orbitofrontal areas. These findings suggest that prefrontal modulation may be an essential component in the development of punding behavior in patients with PD.

    This study evaluates spelling errors in the three subtypes of primary progressive aphasia (PPA): agrammatic (PPA-G), logopenic (PPA-L), and semantic (PPA-S). Forty-one PPA patients and 36 age-matched healthy controls were administered a test of spelling. The total number of errors and types of errors in spelling to dictation of regular words, exception words and nonwords, were recorded. Error types were classified based on phonetic plausibility. In the first analysis, scores were evaluated by clinical diagnosis. Errors in spelling exception words and phonetically plausible errors were seen in PPA-S. Conversely, PPA-G was associated with errors in nonword spelling and phonetically implausible errors. In the next analysis, spelling scores were correlated to other neuropsychological language test scores. Significant correlations were found between exception word spelling and measures of naming and single word comprehension. Nonword spelling correlated with tests of grammar and repetition. Global language measures did not correlate significantly with spelling scores, however. Cortical thickness analysis based on MRI showed that atrophy in several language regions of interest were correlated with spelling errors. Atrophy in the left supramarginal gyrus and inferior frontal gyrus (IFG) pars orbitalis correlated with errors in nonword spelling, while thinning in the left temporal pole and fusiform gyrus correlated with errors in exception word spelling. Additionally, phonetically implausible errors in regular word spelling correlated with thinning in the left IFG pars triangularis and pars opercularis. Together, these findings suggest two independent systems for spelling to dictation, one phonetic (phoneme to grapheme conversion), and one lexical (whole word retrieval).

    Full Text Available Requiring only 10-15 minutes to complete, the UCSD Performance-Based Skills Assessment (UPSA-B has high clinical utility as a brief measure of functional capacity. This study aimed to validate the UPSA-B in adults living with HIV/AIDS (HIV+, and identify whether the UPSA-B can be used as an indicator of functional dependence in this population.One hundred and three HIV+ adults and 91 HIV- adults completed a comprehensive neuropsychological and neuromedical battery, including a self-report measure of functional status (IADL Dependence vs. IADL Independence, an objective measure of functional capacity (UPSA-B, and a self-report measure of mood states including a subscale related to cognitive difficulties (Profile of Mood States [POMS]-Confusion/Bewilderment subscale.HIV+ participants had significantly lower UPSA-B scores than their HIV- counterparts (p = 0.02, although this fell to a trend (p = 0.08 when including covariates. Among the HIV+ group, higher UPSA-B scores were related to better neuropsychological ability, but unrelated to self-reported functional independence. Conversely, UPSA-B scores were unrelated to participant-reported cognitive difficulties on the POMS Confusion/Bewilderment subscale. An ROC curve was generated to determine the optimal UPSA-B value for discriminating between normal neuropsychological functioning versus neuropsychological impairment, with results indicating an optimal cutoff of 79. The UPSA-B identified HIV+ persons with cognitive impairment with 70.9% accuracy.The UPSA-B was able to differentiate neuropsychological impairment from no impairment among HIV+ participants and holds promise as a clinical screening tool in this population. However, indicators of functional disability among adults living with HIV is still not well understood and is likely multifactorial in nature. These data highlight the complex interplay between objective functional capacity, neurocognitive ability, subjective cognitive symptoms, and

    Advances in imaging technology, coupled with military personnel returning home from Iraq and Afghanistan with traumatic brain injury (TBI) and/or post-traumatic stress disorder (PTSD), have increased interest in the neuropsychology and neurobiology of these two conditions. There has been a particular focus on differential diagnosis. This paper provides an overview of findings regarding the neuropsychological and neurobiological underpinnings of TBI and for PTSD. A specific focus is on assessment using neuropsychological measures and imaging techniques. Challenges associated with the assessment of individuals with one or both conditions are also discussed. Although use of neuropsychological and neuroimaging test results may assist with diagnosis and treatment planning, further work is needed to identify objective biomarkers for each condition. Such advances would be expected to facilitate differential diagnosis and implementation of best treatment practices.

    Historically, clinical neuropsychology has made significant contributions to the understanding of brain-behavior relationships, particularly in neurological conditions. During the past several decades, neuropsychology has also become established as an important discipline in psychiatric settings. Cognition is increasingly recognized as being core to psychiatric illnesses and predictive of functional outcomes, augmenting theories regarding symptomatology and illness progression. Adult-type psychiatric disorders (including schizophrenia and other psychotic, mood, anxiety, eating, substance-related, and personality disorders) typically emerge during adolescence or young adulthood, a critical neurodevelopmental period. Clinical neuropsychological assessment in adolescent psychiatric patients is particularly valuable in informing clinical formulation and intervention and can be therapeutic across a number of levels. This article articulates the theoretical considerations and practical challenges and applications of clinical neuropsychology within adolescent and young-adult psychiatry. The importance of considering the neurodevelopmental context and its relationship to current theoretical models underpinning clinical practice are discussed.

    In recent years, the National Academy of Neuropsychology and other professional neuropsychological organizations have published a number of articles and position papers regarding the use, education, and training of psychometrists ("technicians"). Although these documents provide guidelines for the suggested qualifications and training procedures of psychometrists, none make any mention of the need for a standardized credentialing process, which is commonly required of technicians in similar fields, especially in medical settings. Given the recent changes in current procedural Terminology codes used to bill for neuropsychological services and the interpretation of legislation disallowing the use of psychometrists in New York, the need for a standard credential for psychometrists is apparent. This article will review the history and current use of psychometrists in clinical neuropsychology and highlight the need and rationale for the credentialing of psychometrists.

    This is an invited paper for a special issue. The objective was to review history, educational and training pathways, licensure and board certification, practice and compensation, and unique aspects of, or challenges faced by, neuropsychology in mainland China. Historical, scientific, and clinical literatures were reviewed and integrated. The history of neuropsychology in mainland China is traced back to the late 1930s. Educational pathways have not yet been fully formalized. Clinical practice generally occurs within rehabilitation settings, and medical license is required. The main challenge lies in the establishment of training guidelines and the expansion of neuropsychology to meet the tremendous needs of a large nation. Although the development and status of psychology has gradually gained momentum in mainland China, the development of neuropsychology has not shown significant advancement since the late 1930s.

    Full Text Available Aims: To pilot a neuropsychological battery for diagnosing dementia and provide normative scores in an elderly Sri Lankan sample. Materials and Methods: Consecutive subjects over the age of 60 yrs were administered tests assessing the individual domains of language, verbal episodic memory, visual perceptuospatial skills and executive functions in the Sinhala language. Results: There were a total of 230 subjects in the final sample. The mean age of the entire sample was 69 years, mean education level was 12 years and the sample comprised 53% female. One-month test-retest reliability ranged from 0.71 to 0.85 for the various tests. Most tests were significantly influenced by age and education level but not gender. The exceptions to this were some language subtests (repetition, grammar comprehension and word picture matching and two tests of executive functioning (maze completion and alternate target cancellation, which were uninfluenced by age. The subtests where ceiling performance was attained by almost all subjects were repetition, grammar comprehension and word picture matching from the language domain, dot position discrimination from the visuospatial domain and maze completion test from the executive function domain. Scores for various tests after stratifying subjects by age and educational level are given. Conclusions: The tests were well received and could provide a basis for cognitive profiling in similar settings elsewhere.

    Juvenile neuronal ceroid lipofuscinosis (Batten disease) is a progressive and fatal autosomal-recessive inherited lysosomal storage disorder of childhood. Core symptoms include vision loss, seizures, and mental and motor decline. This article presents data from 2 studies of neuropsychological function in juvenile neuronal ceroid lipofuscinosis. In the first cross-sectional pilot study, 15 children with genetic or clinicopathologic confirmation of juvenile neuronal ceroid lipofuscinosis completed a brief test of attention (mean age = 14.3 +/- 2.9 years, range = 8.75-18.74 years; 7 males, 8 females). Average attention performances were significantly below age-expected normative data. A second longitudinal study was then initiated to study neuropsychological function in greater depth, including change in function over time. The authors have enrolled 18 children to date (mean age = 12.88 +/- 3.59 years, range = 6.26-18.65; 11 males, 7 females). Of these, 5 children have completed a second (annual) re-evaluation. Results thus far indicate significant impairment in domains of auditory attention, memory, estimated verbal intellectual function, and verbal fluency. Neuropsychological impairment was significantly correlated with disease duration and with motor function as assessed by a disease-specific clinical neurologic rating scale. There was no significant difference between males and females in neuropsychological test performance. Neuropsychological function was worse among children with a positive seizure history. Juvenile neuronal ceroid lipofuscinosis-affected children exhibited significant and pervasive impairments on tests of auditory attention, verbal memory and repetition, verbal fluency, and an estimate of verbal intellectual ability. Preliminary follow-up data from an annual reassessment showed progressive declines in cognitive function, in particular on a task of working memory. Neuropsychological deficits are pervasive and progressive. Future research will

    Traditional cognitive assessment in neurological conditions involving physical disability is often prevented by the presence of verbal-motor impairment; to date, an extensive motor-verbal-free neuropsychological battery is not available for such purposes. We adapted a set of neuropsychological tests, assessing language, attentional abilities, executive functions and social cognition, for eye-tracking (ET) control, and explored its feasibility in a sample of healthy participants. Thirty healthy subjects performed a neuropsychological assessment, using an ET-based neuropsychological battery, together with standard "paper and pencil" cognitive measures for frontal (Frontal Assessment Battery-FAB) and working memory abilities (Digit Sequencing Task) and for global cognitive efficiency (Montreal Cognitive Assessment-MoCA). Psychological measures of anxiety (State-Trait Anxiety Inventory-Y-STAI-Y) and depression (Beck Depression Inventory-BDI) were also collected, and a usability questionnaire was administered. Significant correlations were observed between the "paper and pencil" screening of working memory abilities and the ET-based neuropsychological measures. The ET-based battery also correlated with the MoCA, while poor correlations were observed with the FAB. Usability aspects were found to be influenced by both working memory abilities and psychological components. The ET-based neuropsychological battery developed could provide an extensive assessment of cognitive functions, allowing participants to perform tasks independently from the integrity of motor or verbal channels. Further studies will be aimed at investigating validity and usability components in neurological populations with motor-verbal impairments.

    Full Text Available Patients with obstructive sleep apnea syndrome (OSAS may have impaired neuropsychological performance. The aim of the study is to assess neuropsychological function in OSAS patients before and on continous positive airway pressure (CPAP therapy to assess different neuropsychological tests – especially of sensomotor memory – in OSAS patients, and to relate neuropsychological test results to polysomnographic findings. Therefore, 36 normal controls and 18 OSAS patients performed tests of attention capacity and memory with retrieval in the evening and the following morning. Six weeks later, the tests were repeated (patients on CPAP. Controls performed significantly better than patients in the tests of attention and of memory of facts without and on CPAP therapy. Moreover, good compliance of CPAP therapy was not associated with better performance. However, there was no significant difference between controls and patients in the tests of sensomotor memory. The neuropsychological results depended on oxygen values, the arousal index, and sleep stages. There is no group difference in overnight improvement in the neuropsychological tests, which could indicate that sleep has an important function in homeostatic regulation rather than in consolidation.

    Previous studies have demonstrated that acute poisoning from exposure to organophosphate (OP) pesticides in agricultural workers causes adverse health effects. However, neuropsychological and cognitive effects of chronic occupational exposure to OP pesticides remain controversial. To identify, evaluate, and systematize existing evidence regarding chronic exposure to OP pesticides and neuropsychological effects in farmworkers. Using the PubMed search engine, a systematic review process was implemented and replicated according to the PRISMA statement. Eligibility criteria included workers over 18 years of age exposed to OP pesticides as well as assessment of neuropsychological and cognitive functioning. Search terms were in English and Spanish languages and included organophosphate and workers. Of the search results, 33 of 1,256 articles meet eligibility criteria. Twenty-four studies found an association between chronic occupational exposure to OP pesticides and low neuropsychological performance in workers. We classified nine of the studies to have study design limitations. Studies indicated occupational exposure to OP pesticides is linked to difficulties in executive functions, psychomotor speed, verbal, memory, attention, processing speed, visual-spatial functioning, and coordination. Nine studies find no relationship between OP pesticides exposure and neuropsychological performance. Overall, evidence suggests an association between chronic occupational exposure to OP pesticides and neuropsychological effects. However, there is no consensus about the specific cognitive skills affected.

    2010-01-01

    A recent article in this journal (Patterson & Plaut, 2009) argued that cognitive neuropsychology has told us very little over the past 30 or 40 years about "how the brain accomplishes its cognitive business." This may well be true, but it is not important, because the principal aim of cognitive neuropsychology is not to learn about the brain. Its principal aim is instead to learn about the mind, that is, to elucidate the functional architecture of cognition. I show that this is so (a) via extensive quotations from leading figures in this field and (b) by analysis of the subject matter of articles in the leading journal in the field, Cognitive Neuropsychology. Recent reviews of the past 25 years of work in this field (Coltheart & Caramazza, 2006) have concluded that cognitive neuropsychology has told us much about the functional architecture of cognition in a variety of cognitive domains. Patterson and Plaut (2009) did not consider this aim of cognitive neuropsychology. Therefore, their conclusions that cognitive neuropsychology has not been successful, and that this is because the particular methods it uses are flawed, are not justified.

    2016-11-01

    The aim of this invited paper for a special issue of international practice in The Clinical Neuropsychologist is to provide information on training models, clinical practice, and professional issues within neuropsychology in Finland. Relevant information was gathered via literature searches, a survey by the Neuropsychology Working Group of the Finnish Psychological Association, archives of the Finnish Neuropsychological Society, and personal communication with professionals in Finland. The roots of Finnish neuropsychology are linked to the early German tradition of experimental psychology. Since the 1970s, it has been strongly influenced by both the psychometric approach in the U.S. and the qualitative approach by Luria. Systematic specialization training program began in Finland in 1983. It was first organized by the Finnish Neuropsychological Society and since 1997 by Finnish universities. At present, around 260 neuropsychologists have completed this training. According to the survey by the Finnish Psychological Association in 2014, 67% of Finnish neuropsychologists work in the public sector, 36% in the private sector, and 28% reported that they had private practice. Work includes assessments for 90% of the respondents, rehabilitation for 74%, and many are involved in teaching and research. Of the respondents, 20% worked both with adults and children, 44% with adults only and 36% with children only. Within test development, pediatric neuropsychology is an especially prominent field. A unique blend of approaches and a solid systematic training tradition has led to a strong position of neuropsychologists as distinguished experts in the Finnish health care system.

    1994-01-01

    Full Text Available A general neuropsychological test battery was assembled and individually given to a 98-subject sample, aged 11–12 years old. The battery included some basic and common tests routinely used in the evaluation of language, memory, spatial abilities, concept formation, and praxic abilities. Twenty-five different scores were calculated. A factor analysis with varimax rotation disclosed nine different factors, accounting for about 70% of the variance. Factor I was measured by a Sequential Verbal Memory test and Verbal Fluency subtests (“verbal factor”. Factor II was measured by the Wechsler Memory Scale Visual Memory subtests (immediate and delayed reproduction, and the Rey-Osterrieth Complex Figure (copy and immediate reproduction (“non-verbal memory and constructional factor”. Factor III was measured by the WMS Logical Memory subtests (immediate and delayed; “verbal memory factor”. Factor IV was associated with fine movements (tapping subtests, right and left hand; “fine movements factor”. Factor V was specially measured by the Information subtest of the WMS and the Boston Naming Test (“verbal knowledge”. Factor VI represented a “praxic ability factor” (ideomotor praxis tests. Delayed Associative Learning subtest measured Factor VII; and Digits measured Factor VIII. Factor IX was a “mental control factor” (Mental Control subtest of the Wechsler Memory Scale. The implications of these results to theories relating to the structure of cognitive activity are discussed.

    The present study aimed to examine if bilingualism affects executive functions and verbal fluency in Marathi and Hindi, two major languages in India, with a considerable cognate (e.g., activity is actividad in Spanish) overlap. A total of 174 native Marathi speakers from Pune, India, with varying levels of Hindi proficiency were administered tests of executive functioning and verbal performance in Marathi. A bilingualism index was generated using self-reported Hindi and Marathi proficiency. After controlling for demographic variables, the association between bilingualism and cognitive performance was examined. Degree of bilingualism predicted better performance on the switching (Color Trails-2) and inhibition (Stroop Color-Word) components of executive functioning; but not for the abstraction component (Halstead Category Test). In the verbal domain, bilingualism was more closely associated with noun generation (where the languages share many cognates) than verb generation (which are more disparate across these languages), as predicted. However, contrary to our hypothesis that the bilingualism “disadvantage” would be attenuated on noun generation, bilingualism was associated with an advantage on these measures. These findings suggest distinct patterns of bilingualism effects on cognition for this previously unexamined language pair, and that the rate of cognates may modulate the association between bilingualism and verbal performance on neuropsychological tests.

    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.

    To characterise the nature of cognitive change in Creutzfeldt-Jakob disease (CJD). Case histories are reported of four patients with sporadic (sCJD) and two with familial CJD (fCJD), with postmortem pathological findings in four cases. The data derived from cognitive examination are examined with respect to the presence or absence of a variety of characteristics to elicit performance profiles across cognitive domains. Three patients with sCJD exhibited clear focal cortical deficits. One patient had visual impairment leading to cortical blindness, associated with posterior hemisphere abnormalities on single photon emission computed tomography (SPECT) imaging; two others had impairments in language, mirrored by left hemisphere SPECT abnormalities. The remaining three patients showed no specific cortical symptomatology. Despite these differences all six patients shared common qualitative characteristics: episodic unresponsiveness, interference effects, and profound verbal and motor perseveration. These common features are interpreted in terms of impaired activation and regulation of neocortex from subcortical structures. Findings from postmortem pathological examination and from the published literature provide converging evidence to implicate a critical role of the thalamus. These preliminary findings suggest that sCJD and fCJD may be associated with distinct neuropsychological characteristics.

    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.

    Sleep disturbance, common among children with ADHD, can contribute to cognitive and behavioral dysfunction. It is therefore challenging to determine whether neurobehavioral dysfunction should be attributed to ADHD symptoms, sleep disturbance, or both. The present study examined parent-reported sleep problems (Children's Sleep Habits Questionnaire) and their relationship to neuropsychological function in 64 children, aged 4-7 years, with and without ADHD. Compared to typically developing controls, children with ADHD were reported by parents to have significantly greater sleep disturbance--including sleep onset delay, sleep anxiety, night awakenings, and daytime sleepiness--(all p ≤ .01), and significantly poorer performance on tasks of attention, executive control, processing speed, and working memory (all p sleep disturbance was significantly associated with deficits in attention and executive control skills (all p ≤ .01); however, significant group differences (relative to controls) on these measures remained (p sleep disturbance. While sleep problems are common among young children with ADHD, these findings suggest that inattention and executive dysfunction appear to be attributable to symptoms of ADHD rather than to sleep disturbance. The relationships among sleep, ADHD symptoms, and neurobehavioral function in older children may show different patterns as a function of the chronicity of disordered sleep.

    Fellow status is an honor bestowed on American Psychological Association (APA) members who have made unusual and outstanding contributions to the field of psychology that have had a national impact. Thus far no studies have examined the characteristics of the individuals who have received this honor. This study examined publicly available data for 157 Division 40 Fellows. Fellows comprise 3.7% of the 4273 members of the division compared to 5.7% of the entire APA membership. Fellows are predominantly male (73%). All but two fellows had earned a Ph.D. with the average time since granting of the doctoral degree of 17.1 ± 6 years (median=16 years) with a range of 7-40 years post-degree. Slightly over half of the fellows hold board certification (53%) in the American Board of Professional Psychology. The largest group of fellows reports their primary employment currently as a university-affiliated medical setting (48%). These data serve to characterize current Division 40 Fellows for the field of neuropsychology and may provide useful information to assist prospective fellow applicants.

  3. Pagophagia improves neuropsychological processing speed in iron-deficiency anemia.

    Pagophagia (compulsive ice chewing) has long been associated with iron deficiency anemia, but prior attempts to account for this craving have been unsatisfactory. We hypothesize that chewing ice triggers vascular changes that lead to preferential or increased perfusion of the brain. This would result in increased alertness and processing speed in anemic patients, but not in healthy controls who are already at ceiling, and would explain why anemic individuals crave ice. Preliminary support for this hypothesis was found in two studies. In Study 1, non-anemic subjects reported very low rates of pagophagia (only 4%) while anemic subjects reported significantly higher rates (56%). In Study 2, chewing ice dramatically improved response time on a neuropsychological test, but only for anemic individuals. In a small randomized controlled trial, iron deficient anemic subjects and healthy controls were assigned to chew ice or drink tepid water and then took a continuous performance test that measures response time, response time variability, errors of impulsivity and errors of inattention. In the water condition, anemic subjects performed significantly worse than healthy controls. Chewing ice had no effect on the performance of healthy controls, but significantly improved the performance of anemic patients. Potential explanations include activation of the dive reflex, which would lead to peripheral vasoconstriction and preferential perfusion of the brain or, alternatively, sympathetic nervous system activation, which would also increase blood-flow to the brain.

    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 neuropsychologic profiles associated with alcoholism are not uniform among individuals. Moreover, within and across research studies, variability among subjects 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. Although the entire brain might be vulnerable in uncomplicated alcoholism, the brain systems that are considered to be most at risk 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. © 2014 Elsevier B.V.

    Stereotactic subcaudate tractotomy is a surgical procedure performed for the alleviation of intractable affective disorders. It involves the destruction of bifrontal pathways located beneath and in front of the head of the caudate nucleus. We report the first prospective study of the neuropsychological correlates of this operation in 23 patients. Tests of general intelligence, speed and attention, as well as a wide range of focal cognitive tests, including tasks which have been reported in the literature to be sensitive to frontal lobe dysfunction, were administered 1 wk before the operation, 2 wks after the operation and approximately 6 mths after the operation. The results indicated that this operation does not cause any significant, long-term adverse, cognitive deficits. In the post-operative assessment, however, patients show a significant deterioration in their performance on recognition memory tests and a large proportion of them present with a marked tendency to confabulate on recall tasks. In addition, their performance on some of the tasks which are considered to be sensitive to frontal lobe dysfunction is found to be significantly impaired. These deficits are interpreted to reflect frontal lobe dysfunction due to widespread post-operative oedema rather than damage to the subcaudate pathways. The potential for research on these transient effects of the operation for the advancement of our understanding of frontal lobe functions is discussed.

  7. Neurological implications and neuropsychological considerations on folk music and dance.

    Sironi, Vittorio A; Riva, Michele A

    2015-01-01

    Neurological and neuropsychological aspects of folk music and traditional dance have been poorly investigated by historical and scientific literature. Some of these performances could be indeed the manifestation of latent pathological conditions or the expression of liberation rituals. This chapter aimed at analyzing the relationships between traditional dance, folk music, and neurological and psychiatric disorders. Since ancient times, dance has been used in the individual or collective as treatment of some diseases, including epilepsy and movement disorders (dyskinesia, chorea, etc.). Dionysia in Ancient Greece, St. Vitus dance in the Middle Age, tarantism and other traditional dances of southern Italy and of non-Western countries might be credited as curative rituals of these neurological and psychiatric conditions. During the nineteenth century, dance was also used for the treatment of psychiatric patients; the relationship between dance and insanity could also be reflected in classical ballets and music of that period. Nowadays, neuropsychiatric manifestations could also be evidenced in modern dances (mass fainting at rock concerts, flash mobs); some ballroom dances are commonly used for the rehabilitation of patients suffering from neurodegenerative and psychiatric conditions. Interdisciplinary research on these subjects (ethnomusicology and cultural anthropology, clinical neurology and dynamic psychology, neuroradiology and neurophysiology, and socioneurology and neuromusicology) should be increased. © 2015 Elsevier B.V.

    2013-06-01

    Duchenne muscular dystrophy (DMD) is a genetic condition affecting predominantly boys that is characterized by fatal muscle weakness. While there is no cure, recent therapeutic advances have extended the lifespan of those with DMD considerably. Although the physiological basis of muscle pathology is well-documented, less is known regarding the cognitive, behavioral, and psychosocial functioning of those afflicted. Several lines of evidence point to central nervous system involvement as an organic feature of DMD, challenging our view of the disorder as strictly neuromuscular. This report provides a review of the literature on neuropsychological and neurobehavioral functioning in DMD. Recent research identifying associations with DMD and neuropsychiatric disorders is also discussed. Lastly, the review presents implications of findings related to nonmotor aspects of DMD for improving the quality of life in those affected. While the literature is often contradictory in nature, this review highlights some key findings for consideration by clinicians, educators and parents when developing therapeutic interventions for this population.

    2014-01-01

    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.

    Cognitive neuropsychology focuses on the concepts of dissociation and double dissociation. The performance of number processing and calculation tasks by patients with acquired brain injury can be used to characterise the way in which the healthy cognitive system manipulates number symbols and quantities. The objective of this study is to determine the components of the numerical processing and calculation system. Participants consisted of 6 patients with acquired brain injuries in different cerebral localisations. We used Batería de evaluación del procesamiento numérico y el cálculo, a battery assessing number processing and calculation. Data was analysed using the difference in proportions test. Quantitative numerical knowledge is independent from number transcoding, qualitative numerical knowledge, and calculation. Recodification is independent from qualitative numerical knowledge and calculation. Quantitative numerical knowledge and calculation are also independent functions. The number processing and calculation system comprises at least 4 components that operate independently: quantitative numerical knowledge, number transcoding, qualitative numerical knowledge, and calculation. Therefore, each one may be damaged selectively without affecting the functioning of another. According to the main models of number processing and calculation, each component has different characteristics and cerebral localisations. Copyright © 2013 Sociedad Española de Neurología.

    2014-03-01

    Autism is a neurodevelopmental disorder that has been associated with atypical brain functioning. Functional connectivity MRI (fcMRI) studies examining neural networks in autism have seen an exponential rise over the last decade. Such investigations have led to the characterization of autism as a distributed neural systems disorder. Studies have found widespread cortical underconnectivity, local overconnectivity, and mixed results suggesting disrupted brain connectivity as a potential neural signature of autism. In this review, we summarize the findings of previous fcMRI studies in autism with a detailed examination of their methodology, in order to better understand its potential and to delineate the pitfalls. We also address how a multimodal neuroimaging approach (incorporating different measures of brain connectivity) may help characterize the complex neurobiology of autism at a global level. Finally, we also address the potential of neuroimaging-based markers in assisting neuropsychological assessment of autism. The quest for a neural marker for autism is still ongoing, yet new findings suggest that aberrant brain connectivity may be a promising candidate.

    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.

  14. Neuropsychological effects of cranial radiation: current knowledge and future directions

    Radiation is an invaluable therapeutic tool in the treatment of cancer, with well-established palliative and curative efficacy. As patient survival has improved, attention has focused on long-range treatment side effects. One such adverse effect, neuropsychological impairment, is incompletely understood. Much of the extant research has been directed at childhood leukemia survivors treated with low-dose whole-brain radiation. Less is known about the effects of high-dose focal or whole-brain radiation used in the treatment of brain lesions. This article reviews the scientific literature in this area, with greatest emphasis on methodologically rigorous studies. Research design considerations are discussed. Review findings suggest that low-dose whole-brain radiation (18 to 24 Gy) in children is associated with mild delayed IQ decline, with more substantial deficits occurring in children treated at a young age. A high incidence of learning disabilities and academic failure is observed in this population and may be caused by poor attention and memory rather than low intellectual level. Children who receive higher dose radiation for treatment of brain tumors experience more pronounced cognitive decline. At higher doses, whole-brain radiation, in particular, is linked to deleterious cognitive outcomes. Remarkably little is known about cognitive outcomes in irradiated adults. Preliminary findings indicate that certain cognitive functions, including memory, may be more vulnerable to decline than others. Suggestions for future research are proposed

    2008-01-01

    The present study analyzes the role of neurocognitive assessment instruments in the detection of the contribution of antipsychotic treatment to cognitive functioning. Recently, a panel of experts suggested six main domains (working memory; attention/vigilance; verbal/visual learning and memory; reasoning and problem solving; speed of processing) implicated in schizophrenia-related cognitive deficits, which serve as a theoretical base for creation of real-time computerized neurocognitive batteries. The high sensitivity of computerized neuropsychological testing is based on their ability to adopt the reaction time (RT) paradigm for the assessment of brain function in a real-time regime. This testing is highly relevant for the monitoring of the cognitive effects of antipsychotics. Computerized assessment assists in the identification of state- and trait-related cognitive impairments. The optimal real-time computerized neurocognitive battery should composite balance between broad and narrow coverage of cognitive domains relevant to the beneficial effects of antipsychotics and will enable better planning of treatment and rehabilitation programs.

    We aimed to evaluate prognostic significance of preoperatively assessed aspartate aminotransaminase (AST)/alanine aminotransferase (ALT) (De Ritis) ratio on survival in bladder cancer (BC) patients underwent radical cystectomy (RC). We, respectively, analysed clinical and pathological data of 153 patients who underwent RC for BC between February 2006 and December 2016 at a tertiary level hospital. The potential prognostic value of De Ritis ratio was assessed by using ROC curve analysis. The effect of the De Ritis ratio was analysed by the Kaplan-Meier method and Cox regression hazard models for patients' disease-specific survival (DSS) and overall survival (OAS). We had 149 BC patients, in total. Mean age was 61.65 ± 9.13 years. One hundred and thirty-nine (93.3%) of the patients were men. According to ROC analysis, optimal threshold of De Ritis ratio for DSS was 1.30. In Kaplan-Meier analyses, the high De Ritis ratio group showed worse progression in DSS and OAS (all parameters, p < 0.001). On Cox regression models of clinical and pathological parameters to predict DSS, De Ritis ratio (HR 5.79, 95% CI 2.25-15.13), pathological T stage (HR 15.89, 95% CI 3.92-64.33, in all p < 0.001); and to predict OAS, De Ritis ratio (HR 2.61, 95% CI 1.49-4.56; p < 0.001), pathological T stage (HR 5.42, 95% CI 2.63-11.64; p < 0.001) and age (HR 1.05, 95% CI 1.02-1.08; p = 0.001) were determined as independent prognostic factors. Preoperative elevated De Ritis ratio could be an independent prognostic factor in BC patients underwent RC. Our results should be confirmed by large and properly designed prospective, randomized trials.

    Optimal enteral immunonutrition (EIN) regime for gastric cancer (GC) patients underwent gastrectomy remains uncertainty. To assess comparative efficacy of different EIN formulas in GC patients underwent gastrectomy, we performed network meta-analysis. We included 11 RCTs enrolling 840 patients. Pairwise meta-analysis indicated that EIN (RR 0.56, 95% CI 0.36-0.86; MD -0.42, 95% CI -0.74-0.10), Arg+RNA+ω-3-FAs (RR 0.37, 95% CI 0.22-0.63; MD -0.42, 95% CI -0.75-0.07), Arg+Gln+ω-3-FAs (RR 0.22, 95% CI 0.05-0.94; MD -0.69, 95% CI -1.22-1.07) reduced ICs and LOS. Network meta-analysis confirmed the potential of Arg+RNA+ω-3-FAs for ICs (OR 0.27, 95% Crl 0.12-0.49) and Arg+Gln+ω-3-FAs for CIs (OR 0.22, 95% Crl 0.02-0.84) and LOS (SMD -0.63, 95% Crl -1.07-0.13), and indicated that Arg+RNA+ω-3-FAs was superior to Arg+RNA and Arg+Gln for ICs as well. We performed direct and network meta-analyses for randomized controlled trials comparing EIN formulas with each other or standard enteral nutrition (SEN) in reducing infectious complications (ICs), noninfectious complications (NICs) and length of hospital stay (LOS), through January 2016. The surface under the cumulative ranking curve (SCURA) and Grading of Recommendations Assessment, Development and Evaluation (GRADE) were used to rank regimes and rate qualities of evidences respectively. As for GC patients underwent gastrectomy, Arg+RNA+ω-3-FAs and Arg+Gln+ω-3-FAs are the optimal regimes of reducing ICs and LOS.

    Hepatitis A is generally known as a mild, self-limiting disease of the liver, but in rare instances it can progress to fulminant hepatitis, which may require liver transplantation for recovery. Such cases are known to be related to old age and underlying liver disease. We report four cases of hepatitis A in which patients presented with fulminant hepatitis and acute renal failure and underwent liver transplantation. The following common features were observed in our cases: (1) occurrence in relatively old age (>/=39 years old), (2) association with acute renal failure, (3) presence of hepatomegaly, and (4) microscopic features of submassive hepatic necrosis.

    Conclusion: In our experience, MACE events were not higher in patients with FFR > 0.8 and kept under medical therapy and were similarly lower in patients with FFR ≤0.8 and underwent revascularisation (p = 0.73. Also MACE events were higher in patients with FFR ≤ 0.8 and did not undergo revascularisation compared to other two appropriately treated groups (p = 0.03. FFR based revascularization decision appears to be a safe strategy in Indian patients.

    A 2-year-and-4-month-old female infant, 12 kg in weight and 90 cm in height fell off from a table, which was about 1 m height with a toothbrush in her mouth without her parents noticing. Urgent CT scan showed that it penetrated the left side of her oropharyngeal wall to the bifurcation of her right carotid artery. According to the initial assessment, carotid artery seemed intact and there seemed to be no sign of CNS involvement. She underwent general anesthesia for further investigation and operation. We could detect vocal code with ease by inserting Glidescope between her tongue and the toothbrush. After the intubation, we administered fentanyl 25 μg rocuronium 15 mg and sevoflulane 3-5% to her, and then she underwent arteriography. The neurosurgeon found no sign of major arterial injury nor traumatic aneurysm nor CNS involvement. She went to the ICU intubated after the removal of the toothbrush. She was extubated 5 days after operation. One of the benefits of the Glidescope is that we can share the visual image, and we chose it this time. When we expect a difficult airway during management for oropharyngeal trauma, we have to consider the way to manage the airway.

    Full Text Available Citrus aurantium is rich in flavonoids, which may prevent osteosarcoma progression, but its related molecular mechanism remains unclear. Flavonoids were extracted from C. aurantium and purified by reparative HPLC. Each fraction was identified by using electrospray ionisation mass spectrometry (ESI-MS. Three main components (naringin, naringenin, and hesperetin were isolated from C. aurantium. Naringenin inhibited the growth of MG-63 cells, whereas naringin and hesperetin had no inhibitory function on cell growth. ROS production was increased in naringin- and hesperetin-treated groups after one day of culture while the level was always lowest in the naringenin-treated group after three days of culture. 95 osteosarcoma patients who underwent surgery were assigned into two groups: naringenin group (NG, received 20 mg naringenin daily, n=47 and control group (CG, received 20 mg placebo daily, n=48. After an average of two-year follow-up, osteosarcoma volumes were smaller in the NG group than in the CG group (P>0.01. The rate of osteosarcoma recurrence was also lower in the NG group than in CG group. ROS levels were lower in the NG group than in the CG group. Thus, naringenin from Citrus aurantium inhibits osteosarcoma progression and local recurrence in the patients who underwent osteosarcoma surgery by improving antioxidant capability.

    Malnutrition has been identified as an important predictor of poor clinical outcomes in patients with heart failure. The aim of this study is to examine the prognostic impact of nutritional status in patients with coronary artery disease (CAD) who underwent percutaneous coronary intervention (PCI). The impact of nutrition, assessed using the geriatric nutritional risk index (GNRI) calculated by serum albumin and body mass index, was evaluated in 2,853 patients with CAD who underwent their first PCI between 2000 and 2011. Patients were assigned to tertiles based on their GNRI levels. The incidences of all-cause death and cardiac death were assessed. The median GNRI values were 101 (interquartile range 95 to 106). Lower GNRI levels were associated with older age and higher prevalence of acute coronary syndrome and chronic kidney disease. During the median follow-up period of 7.4 years, Kaplan-Meier curves showed ongoing divergence in rates of mortality among tertiles (GNRI nutritional status was associated with long-term clinical outcomes in CAD patients after PCI. Evaluation of GNRI carries important prognostic information and may guide the therapeutic approach to such patients. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available Abstract Objetive: Saline-irrigated radiofrequency ablation, which has been widely used for surgical treatment of atrial fibrillation in recent years, is 80-90% successful in achieving sinus rhythm. In our study, our surgical experience and mid-term results in patients who underwent mitral valve surgery and left atrial radiofrequency ablation were analyzed. Methods: Forty patients (15 males, 25 females; mean age 52.05±9.9 years; range 32-74 underwent surgery for atrial fibrillation associated with mitral valvular disease. All patients manifested atrial fibrillation, which started at least six months before the surgical intervention. The majority of patients (36 patients, 90% were in NYHA class III; 34 (85% patients had rheumatic heart disease. In addition to mitral valve surgery and radiofrequency ablation, coronary artery bypass, DeVega tricuspid annuloplasty, left ventricular aneurysm repair, and left atrial thrombus excision were performed. Following discharge from the hospital, patients' follow-up was performed as outpatient clinic examinations and the average follow-up period of patients was 18±3 months. Results: While the incidence of sinus rhythm was 85.3% on the first postoperative day, it was 80% during discharge and 71% in the 1st year follow-up examination. Conclusion: Radiofrequency ablation is an effective method when it is performed by appropriate surgical technique. Its rate for returning to sinus rhythm is as high as the rate of conventional surgical procedure.

    Listening and reading comprehension of paragraph-length material are considered higher-order language skills fundamental to social and academic functioning. Using ecologically relevant language stimuli that were matched for difficulty according to developmental level, we analyze the effects of task, age, neuropsychological skills, and post-task performance on fMRI activation and hemispheric laterality. Areas of supramodal language processing are identified, with the most robust region being left-lateralized activation along the superior temporal sulcus. Functionally, this conjunction has a role in semantic and syntactic processing, leading us to refer to this conjunction as "comprehension cortex." Different from adults, supramodal areas for children include less extensive inferior frontal gyrus but more extensive right cerebellum and right temporal pole. Broader neuroanatomical pathways are recruited for reading, reflecting the more active processing and larger set of cognitive demands needed for reading compared to listening to stories. ROI analyses reveal that reading is a less lateralized language task than listening in inferior frontal and superior temporal areas, which likely reflects the difficulty of the task as children in this study are still developing their reading skills. For listening to stories, temporal activation is stable by age four with no correlations with age, neuropsychological skills or post-task performance. In contrast, frontal activation during listening to stories occurs more often in older children, and frontal activation is positively correlated with better performance on comprehension questions, suggesting that the activation of frontal networks may reflect greater integration and depth of story processing. 2010 Elsevier Inc.

    Full Text Available The academic debate nowadays is focused on producing an applied science of learning, aiming to teach students how to learn and be strategic in their acquisition. The aim of the study is to identify and discuss the reading comprehension instruction approach applied in the Albanian system of education. Findings from 10 classes of Albanian language and literature with students of third grade were directly observed and analyzed, in order to gather evidence based on indicators and instruments that assess the way of reading comprehension. Findings were categorized according to strategy use; the frequency of their application in different classes was counted and represented in percentages. In this paper we will try to respond to questions like: What are students' main barriers of comprehending? Does the instructional approach respond to students’ needs and level of comprehension? Are teachers prepared to teach comprehension strategies? Furthermore, examples of procedures on how to deliver instruction of comprehension strategies in natural contexts will be represented. Results from teacher practices during lessons of reading comprehension confirmed that teachers use limited teaching strategies to deliver lessons. They mainly use strategies to test comprehension; while the approach of teaching students to read independently and strategically is an unknown practice.

    Previous research suggests that being interrupted while reading a text does not disrupt the later recognition or recall of information from that text. This research is used as support for Ericsson and Kintsch's (1995) long-term working memory (LT-WM) theory, which posits that disruptions while reading (e.g., interruptions) do not impair subsequent text comprehension. However, to fully comprehend a text, individuals may need to do more than recognize or recall information that has been presented in the text at a later time. Reading comprehension often requires individuals to connect and synthesize information across a text (e.g., successfully identifying complex topics such as themes and tones) and not just make a familiarity-based decision (i.e., recognition). The goal for this study was to determine whether interruptions while reading disrupt reading comprehension when the questions assessing comprehension require participants to connect and synthesize information across the passage. In Experiment 1, interruptions disrupted reading comprehension. In Experiment 2, interruptions disrupted reading comprehension but not recognition of information from the text. In Experiment 3, the addition of a 15-s time-out prior to the interruption successfully removed these negative effects. These data suggest that the time it takes to process the information needed to successfully comprehend text when reading is greater than that required for recognition. Any interference (e.g., an interruption) that occurs during the comprehension process may disrupt reading comprehension. This evidence supports the need for transient activation of information in working memory for successful text comprehension and does not support LT-WM theory. (c) 2015 APA, all rights reserved).

    Full Text Available Quotients and comprehension are fundamental mathematical constructions that can be described via adjunctions in categorical logic. This paper reveals that quotients and comprehension are related to measurement, not only in quantum logic, but also in probabilistic and classical logic. This relation is presented by a long series of examples, some of them easy, and some also highly non-trivial (esp. for von Neumann algebras. We have not yet identified a unifying theory. Nevertheless, the paper contributes towards such a theory by introducing the new quotient-and-comprehension perspective on measurement instruments, and by describing the examples on which such a theory should be built.

    Full Text Available This article discusses the evolution of modern neuropsychology as a field and the concomitant changes in the Diagnostic and Statistical Manual of Mental Disorders (DSM. Themes in neuropsychology through the years will be highlighted alongside discussion of how neuropsychologists and neuropsychological research have influenced and have been influenced by the DSM. The DSM 5 attention-deficit/hyperactivity disorder and mild neurocognitive disorder will be used as examples to reflect the evolution of the disorders in relation to neuropsychology and the DSM. In particular, recent criticism and research regarding the nosology of both disorders and future directions will be presented in the context of neuropsychology and DSM. Finally, influence regarding changes to the DSM 5 on neuropsychology in clinical decision making, test selection, and diagnosis will be discussed.

    Full Text Available BACKGROUND: Untreated GH-deficient adults have a diversity of dysfunctions (e.g. reduced muscle strength, emotional instability during stress, depressive symptoms that may cause deleterious effects on quality of life, and may be positively influenced by recombinant human growth hormone (rh-GH therapy. AIM: To evaluate the impact of a clinical intervention with rh-GH therapy on GH - deficient adults. METHOD: The physical, psychiatric and neuropsychological status of 9 GH-deficient adults was determined before and after the administration of rh-GH (0.250 IU/Kg/week in a double blind placebo-controlled trial for six months. Patients then received rh-GH for a further period of 6 months and their status was re-evaluated. RESULTS: Rh-GH was significant better than placebo at 6th month (p<0.05, producing increased serum Insulin like growth factor-I (IGF-1 levels, reduced body mass index (BMI and body fat, increased lean body mass and water, reduced waist/hip ratio and increased energy expenditure. The rh-GH therapy was also significantly better than placebo on depressive features as measured by the Hamilton Depression Scale (17-items (p= 0.0431 and the Beck Depression Inventory (p= 0.0431. Neuropsychological evaluations showed significant improvements in measures of Attention: Digit Backward (p= 0.035,Verbal Fluency (FAS (p= 0.02 and Cognitive Efficiency (WAIS-R tests: Vocabulary (p= 0.027 , Picture Arrangements (p= 0.017, and Comprehension (p= 0.01 following rh-GH therapy.

    To investigate whether analgesic and sedative drug use during PICU treatment is associated with long-term neurodevelopmental outcome in children who survived meningococcal septic shock. This study concerned a secondary analysis of data from medical and psychological follow-up of a cross-sectional cohort of all consecutive surviving patients with septic shock and purpura requiring intensive care treatment between 1988 and 2001 at the Erasmus MC-Sophia Children's Hospital. At least 4 years after PICU admission, these children showed impairments on several domains of neuropsychological functioning. In the present study, type, number, and dose of sedatives and analgesics were retrospectively evaluated. Tertiary care university hospital. Seventy-seven meningococcal septic shock survivors (median age, 2.1 yr). None. Forty-five patients (58%) received one or more analgesic and/or sedative drugs during PICU admission, most commonly benzodiazepines (n = 39; 51%), followed by opioids (n = 23; 30%). In total, 12 different kinds of analgesic or sedative drugs were given. The use and dose of opioids were significantly associated with poor test outcome on full-scale intelligence quotient (p = 0.02; Z = -2.28), verbal intelligence quotient (p = 0.02; Z = -2.32), verbal intelligence quotient subtests (verbal comprehension [p = 0.01; Z = -2.56] and vocabulary [p = 0.01; Z = -2.45]), and visual attention/executive functioning (Trial Making Test part B) (p = 0.03; Z = -2.17). In multivariate analysis adjusting for patient and disease characteristics, the use of opioids remained significant on most neuropsychological tests. The use of opioids during PICU admission was significantly associated with long-term adverse neuropsychological outcome independent of severity of illness scores in meningococcal septic shock survivors.

    Purpose: To present prospective neuropsychological data at baseline and follow-up in children and young adults with benign and low-grade gliomas treated with focal stereotactic conformal radiotherapy (SCRT). Methods and Materials: A total of 22 patients (age 4-25 years) with residual/progressive benign and low-grade brain tumors considered suitable for SCRT underwent detailed and in-depth neuropsychological and cognitive testing at baseline before SCRT. The test battery included measurement of age-adjusted intelligence quotients (IQs) and cognitive parameters of visual, spatial, visuomotor, and attention concentrations. Anxiety was measured using the State-Trait Anxiety Inventory for Children and Hamilton Anxiety Rating Scale for patients >16 years old. Patients were treated with high-precision conformal radiotherapy under stereotactic guidance to a dose of 54 Gy in 30 fractions. All neuropsychological assessments were repeated at 6 and 24 months after SCRT completion and compared with the baseline values. Results: The baseline mean full-scale IQ before starting RT for patients 16 years, the corresponding value was 72 (range, 64-129). Of 20 evaluable patients, 14 (70%) had less than average IQs at baseline, even before starting radiotherapy. The verbal IQ, performance IQ, and full-scale IQ, as well as other cognitive scores, did not change significantly at the 6- and 24-month follow-up assessments for all patients. The memory quotient in older children and young adults was maintained at 6 and 24 months after SCRT, with a mean value of 93 and 100, respectively, compared with a mean baseline value of 81 before RT. The mean anxiety score in children measured by the C1 and C2 components of the State-Trait Anxiety Inventory for Children (STAIC) was 48 and 40, respectively, which improved significantly to mean values of 30 and 26, respectively, at the 24-month follow-up assessment (p = 0.005). The mean depression score in patients >16 years old was 23 at baseline and had

    The aim of this study was to compare neuropsychological (NP) functioning in patients with Lyme neuroborreliosis (LNB) 30months after treatment to matched controls. We tested 50 patients with LNB and 50 controls with the trail-making test (TMT), Stroop test, digit symbol test, and California Verbal Learning test (CVLT). A global NP sumscore was calculated to express the number of low scores on 23 NP subtasks. Mean scores were lower amongst LNB-treated patients than amongst controls on tasks assessing attention/executive functions: (Stroop test 4: 77.6 vs. 67.0, P=0.015), response/processing speed (TMT 5: 23.4 vs. 19.2, P=0.004), visual memory (digit symbol recall: 6.6 vs. 7.2, P=0.038), and verbal memory (CVLT list B: 4.68 vs. 5.50, P=0.003). The proportion of patients and controls with NP sumscores within one SD from the mean in the control group (defined as normal) and between one and two SD (defined as deficit) were similar, but more LNB-treated patients than controls had a sumscore more than two SD from the mean (defined as impairment) (8 vs. 1, P=0.014). As a group, LNB-treated patients scored lower on four NP subtasks assessing processing speed, visual and verbal memory, and executive/attention functions, as compared to matched controls. The distribution of NP dysfunctions indicates that most LNB-treated patients perform comparable to controls, whilst a small subgroup have a debilitating long-term course with cognitive problems. © 2011 The Author(s).

    Full Text Available Introduction: The test of Stroop on line modality word / color is of limited application in the clinical child population. A digital adaptation of the test demands the infant's quick answer and at the same time that the processes used in the test have an interference in the boy. If the boy doesn't adapt to the digital demands it doesn't happen the interference between the processes and the test he doesn't have effect. Material and Method: The investigation seeks to determine if the results of the test Stroop, modality word / color, they are related with the results of other tests that evaluate the executive functions. The Dpto. of Neuropsychology he intended to revise all the results of the test SESH in the population from 7 to 15 years of the 2009 - 2011. The analyzed tests were: Stroop, Wisconsin, Time of complex reaction and the simple sustained Attention. Result: The clinical histories demonstrated that of the 207 evaluated children 59 present punctuations above the superior norm in the Stroop. However, the results in the Wisconsin, the time of reaction and the attention reports that the 59 children have a pathological index. The investigation shows that the punctuations risen in the Stroop are not sign of good acting in the other tests. Conclusions: The task Stroop is not effective in all the analyzed children. The problems in the prosecution speed and atencionales are a negative condition to execute with success the on-line task Stroop modality word / color in the infantile population.

    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.

    The effects of HIV on brain metabolites and cognitive function are not well understood. Sixteen HIV+youths (15 vertical, 1 transfusion transmissions) receiving combination antiretroviral therapy and 14 age-matched HIV- youths (13-25 years of age) were evaluated with brain two-dimensional (2D) magnetic resonance spectroscopy (MRS) at 3 Tesla (T) and a neuropsychological battery that assessed three cognitive domains (attention/processing speed, psychomotor ability, and executive function). The relationship between brain metabolite ratios and cognitive performance was explored. Compared to HIV- controls, HIV+ subjects had higher sycllo-inositol (Scy)/total creatine (tCr) (+32%, p = 0.016) and higher Scy/total choline (tCho) (+31%, p = 0.018) on 2D-MRS in the right frontal lobe. HIV+ subjects also had higher glutamate (Glu)/tCr (+13%, p = 0.022) and higher Glu/tCho (+15%, p = 0.048) than controls. HIV+ subjects demonstrated poorer attention/processing speed (p = 0.011, d = 1.03) but similar psychomotor and executive function compared to HIV- controls. The attention/processing score also correlated negatively with the ratio of N-acetylaspartate (NAA) to tCr on 2D-MRS (r = -0.75, p = 0.0019) in the HIV- controls, but not in the HIV+ subjects (Fisher's r-z transformation, p < 0.05). Our results suggest that attention/processing speed is impacted by early HIV infection and is associated with right hemisphere NAA/tCr. Scy and Glu ratios are also potential markers of brain health in chronic, lifelong HIV infection in perinatally infected youths receiving antiretroviral therapy.

    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

    In order to evaluate the relation between neuropsychological functions and hemodynamic cerebral ischemia, the author analyzed neuropsychological examination and the cerebral blood flow and metabolism of patients before and after bypass surgery. Twenty-five patients were defined by clinical and laboratory criteria as suffering from hemodynamic cerebral ischemia. All patients had one or more episodes of focal cerebral ischemia due to unilateral internal carotid or middle cerebral artery occlusion. Computerized tomography scans either were normal or showed evidence of watershed infarction. Based on these criteria, superficial temporal artery-proximal middle cerebral artery anastomosis was performed. The baseline cerebral blood flow (CBF), oxygen extraction fraction (OEF), cerebral metabolic rate of oxygen (CMRO 2 ) and cerebrovascular reserve capacity (CVRC) were studied using positron emission computerized tomography (PET) and the acetazolamide test. Neuropsychological evaluations including Hasegawa Dementia Scale-Revised, Mini-Mental State and Wechsler Adult Intelligence Scale-Revised (WAIS-R), and PET study were completed one month after the last ischemic event and 3-6 months after the operation. A significant negative correlation was observed between OEF and neuropsychological functions. Postoperative neuropsychological functions showed significant improvement. Significant correlations were observed for ΔWAIS-R (preoperative WAIS-R postoperative WAIS-R) versus preoperative CMRO 2 (r=0.52), for ΔWAIS-R versus preoperative OEF (r=0.47). In view of these findings, the author concludes that elevation of OEF impairs neuropsychological functions and bypass surgery improves neuropsychological functions in patients with normal CMRO 2 and elevated OEF.

    Children with Attention Deficit/Hyperactivity Disorder (ADHD) have poorer neuropsychological functioning relative to their typically-developing peers. However, it is unclear whether early neuropsychological functioning predicts later ADHD severity and/or the latter is longitudinally associated with subsequent neuropsychological functioning; and whether these relations are different in children with and without early symptoms of ADHD. This study aimed to examine the longitudinal associations b...

  19. A Case of Type 2 Amiodarone-Induced Thyrotoxicosis That Underwent Total Thyroidectomy under High-Dose Steroid Administration

    Full Text Available Amiodarone is used commonly and effectively in the treatment of arrhythmia; however, it may cause thyrotoxicosis categorized into two types: iodine-induced hyperthyroidism (type 1 amiodarone-induced thyrotoxicosis (AIT and destructive thyroiditis (type 2 AIT. We experienced a case of type 2 AIT, in which high-dose steroid was administered intravenously, and we finally decided to perform total thyroidectomy, resulting in a complete cure of the AIT. Even though steroid had been administered to the patient (maximum 80 mg of prednisolone, the operation was performed safely and no acute adrenal crisis as steroid withdrawal syndrome was found after the operation. Few cases of type 2 AIT that underwent total thyroidectomy with high-dose steroid administration have been reported. The current case suggests that total thyroidectomy should be taken into consideration for patients with AIT who cannot be controlled by medical treatment and even in those under high-dose steroid administration.
