    Childhood traumatic brain injury (TBI) is a frequent cause of acquired disability in childhood and can have a serious impact on development across the lifespan. The consequences of early TBI vary according to injury severity, with severe injuries usually resulting in more serious physical, cognitive and behavioral sequelae. Both clinical and research reports document residual deficits in a range of skills, including intellectual function, attention, memory, learning, and executive function. In addition, recent investigations suggest that early brain injury also affects psychological and social development and that problems in these domains may increase in the long term postinjury. Together, these deficits affect children's ability to function effectively at school, in the home, and in their social environment, resulting in impaired acquisition of knowledge, psychological and social problems, and overall reduced quality of life. Ultimately, recovery from childhood TBI depends on a range of complex biological, developmental, and psychosocial factors making prognosis difficult to predict. This chapter will detail the cognitive (intellectual, attentional, mnesic, executive, educational, and vocational) and psychopathological (behavioral, adaptive, psychological, social) sequelae of childhood TBI with a particular focus on postinjury recovery patterns in the acute, short-, and long-term phases, as well as into adulthood.

    Systems-based approaches to neuroscience, using network analysis and the human connectome, have been adopted by many researchers by virtue of recent progress in neuroimaging and computational technologies. Various neurological disorders have been evaluated from a network perspective, including stroke, Alzheimer's disease, Parkinson's disease, and traumatic brain injury. Until now, dynamic processes after stroke and during recovery were investigated through multimodal neuroimaging techniques. Many studies have shown disruptions in structural and functional connectivity, including in large-scale neural networks, in patients with stroke sequela such as motor weakness, aphasia, hemianopia, neglect, and general cognitive dysfunction. A connectome-based approach might shed light on the underlying mechanisms of stroke sequela and the recovery process, and could identify candidates for individualized rehabilitation programs. In this review, we briefly outline the basic concepts of structural and functional connectivity, and the connectome. Then, we explore current evidence regarding how stroke lesions cause changes in connectivity and network architecture parameters. Finally, the clinical implications of perspectives on the connectome are discussed in relation to the cognitive and behavioral sequela of stroke. PMID:26437992

    Central pontine myelinolysis (CPM) is one of the serious neurological complications of alcoholism. This study evaluated magnetic resonance images of sequelae of CPM. Approximately 600 alcoholic patients were examined by a 1.0-T magnetic resonance imaging device, and 11 patients were retrospectively found to have a central pontine lesion, a presumed sequela of CPM. The lesions had various shapes and most were cavitary. In 3 of the 11 patients bilateral symmetrical oval lesions were faintly visible in the middle cerebellar peduncles. These middle cerebellar peduncular lesions were diagnosed as having Wallerian degeneration of the pontocerebellar tract secondary to CPM. (orig.)

    Chronic bronchitis is of enormous epidemiological, socio-medical and economical importance. The main cause of chronic bronchitis is active but also passive cigarette smoking. Other etiologic factors are: viral or bacterial infections, chronic dust exposure in occupational settings and air pollution. Cease of cigarette smoking is considered the most valuable action in the treatment of the chronic bronchitis. In addition to drug therapy, physical therapy and other measures of rehabilitation may be a supportive benefit. ABout 10-20% of all patients with chronic bronchitis develop airway obstruction and/or lung emphysema. Obstructive bronchitis with or without lung emphysema should be treated with corticosteroids, beta 2-agonists and/or theophylline. Evidence for the socio-economical burden of chronic bronchitis and its complications are the enormous costs for the social economy (direct costs: in- and outpatient treatment; indirect costs: premature pensions, sick leave).

    Gestational diabetes is a common complication of pregnancy and occurs in approximately 7% of all pregnancies. It has been associated with an increased rate of congenital anomalies including disturbances of intrauterine growth, delayed brain maturity, and neurobehavioral abnormalities in the offspring. The resulting maternal and fetal metabolic dysfunction leads to diminished iron stores (which can affect red blood cell [RBC] production and subsequent organogenesis), a metabolism-placental perfusion mismatch, increased FFA, increased lactic acidosis, and potential hypoxia. Though most newborns born in the context of gestational diabetes are not significantly affected by it, empirical research suggests gestational diabetes has been associated with lower general intelligence, language impairments, attention weaknesses, impulsivity, and behavioral problems. In extreme cases, it may essentially function as a gestational brain insult. Children who are exposed to poorly controlled gestational diabetes may benefit from some form of tracking or follow-up assessments. Additionally, clinicians evaluating children with developmental learning or cognitive dysfunction may want to seek appropriate gestational diabetes-related information from the parents. A greater understanding of this significant gestational risk may help foster improved prenatal diabetes management and may help reduce the neurodevelopmental effects of gestational diabetes.

    Behavioral and cognitive changes in patients with primary brain tumor (PBT) are common and may be distressing to patients and their family members. Healthcare professionals report a strong need for information, practical strategies, and training to assist consumers and better address management issues. A literature review by the current project found that 53% of the information resources currently available to consumers and health professionals contained minimal or no information about cognitive/behavioral changes after PBT, and 71% of the resources contained minimal or no information on associated strategies to manage these changes. This project aimed to develop an information resource for patients, carers, and health professionals addressing the behavioral and cognitive sequelae of PBT, including strategies to minimize the disabling impact of such behaviors. In consultation with staff and patient groups, 16 key information topics were identified covering cognitive and communication changes and challenging behaviors including executive impairment, behavioral disturbance, and social/emotional dysfunction. Sixteen fact sheets and 11 additional resource sheets were developed and evaluated according to established consumer communication guidelines. Preliminary data show that these resources have been positively received and well utilized. These sheets are the first of their kind addressing challenging behaviors in the neuro-oncology patient group and are a practical and useful information resource for health professionals working with these patients and their families. The new resource assists in reinforcing interventions provided to individual patients and their relatives who are experiencing difficulties in managing challenging behaviors after PBT. PMID:25827649

  20. Neurodegenerative properties of chronic pain: cognitive decline in patients with chronic pancreatitis.

    Directory of Open Access Journals (Sweden)

    Marijtje L A Jongsma

    Full Text Available Chronic pain has been associated with impaired cognitive function. We examined cognitive performance in patients with severe chronic pancreatitis pain. We explored the following factors for their contribution to observed cognitive deficits: pain duration, comorbidity (depression, sleep disturbance, use of opioids, and premorbid alcohol abuse. The cognitive profiles of 16 patients with severe pain due to chronic pancreatitis were determined using an extensive neuropsychological test battery. Data from three cognitive domains (psychomotor performance, memory, executive functions were compared to data from healthy controls matched for age, gender and education. Multivariate multilevel analysis of the data showed decreased test scores in patients with chronic pancreatitis pain in different cognitive domains. Psychomotor performance and executive functions showed the most prominent decline. Interestingly, pain duration appeared to be the strongest predictor for observed cognitive decline. Depressive symptoms, sleep disturbance, opioid use and history of alcohol abuse provided additional explanations for the observed cognitive decline in some of the tests, but to a lesser extent than pain duration. The negative effect of pain duration on cognitive performance is compatible with the theory of neurodegenerative properties of chronic pain. Therefore, early and effective therapeutic interventions might reduce or prevent decline in cognitive performance, thereby improving outcomes and quality of life in these patients.

To evaluate the effect of Danzhi decoction (DZD on chronic pelvic pain (CPP, hemodynamics, and proinflammatory factors of sequelae of pelvic inflammatory diseases (SPID in murine model. Methods. SPID mice were randomly treated with high-dose DZD, mid-dose DZD, low-dose DZD, aspirin, and vehicle for 3 estrous circles. The Mouse Grimace Scale (MGS was performed to evaluate CPP; blood flows of the upper genital tract, pelvic wall, and mesentery were used to assess hemodynamics in SPID mice; expressions of vascular endothelial growth factor (VEGF, angiopoietin-2 (Ang-2, and osteopontin (OPN were measured by Western blot and immunochemistry. Results. Treatment with dose-dependent DZD significantly decreased the MGS scores, accelerated blood flows of the pelvis, and reduced expressions of VEGF, Ang-2, and OPN in the upper genital tract. Conclusions and Discussions. DZD was effective in relieving CPP and improving hemodynamics of the pelvic blood-stasis microenvironment in SPID mice. There was a relationship between CPP and the pelvic blood-stasis microenvironment. Furthermore, DZD might play a positive role in the anti-inflammatory process.

    Full Text Available Objective: to study the specific features of development of cognitive impairments (CIs, the role of traditional cardiovascular risk factors and renal failure-induced factors in patients with Stages I–IV chronic kidney disease (CKD and to assess an association of CIs with the signs of vascular wall remodeling in them. Patients and methods. Fifty-one patients aged 53±10 years with CKD were examined. Among them, there were 20 patients with Stages I–II CKD: a glomerular filtration rate (GFR of і60 ml/min/1.73 m2, signs of renal lesion; 20 with Stages III CKD: a GFR of <60–30 ml/min/1.73 m2, and 11 with Stages VI CKD: a GFR of <30–15 ml/min/1.73 m2. Results and discussion. CIs were more common in the patients with Stages III–IV than in those with Stages I–II, as shown by the scores of the mini-mental state examination (p<0.001, the frontal assessment battery (p=0.001, and the regulatory function test (p<0.001. These tests showed that the magnitude of CIs increased with the higher stage of CKD. Stages III–IV CKD is an independent predictor of CIs in persons with predialysis-stage kidney lesion. CIs were found to be related to hyperhomocysteinemia, anemia, abdominal obesity, left ventricular hypertrophy, and patient age. The signs of atherosclerotic lesion of the common carotid arteries and the indicators of arterial stiffness were also associated with the incidence and magnitude of CIs in CKD. The detection of CIs in patients with early CKD allows one to timely initiate adequate therapy aimed particularly at improving cerebral circulation, eliminating the impact of risk factors, and slowing down the vascular remodeling. The management tactics for patients with CKD must involve the identification and correction of cardiovascular risk factors, and duplex scanning of the wall of the common carotid arteries may be used as a noninvasive method to assess the risk of the development and progression of CIs in predialysis CKD.

    Although neurologic Lyme disease is known to cause cognitive dysfunction in adults, little is known about its long-term sequelae in children. Twenty children with a history of new-onset cognitive complaints after Lyme disease were compared with 20 matched healthy control subjects. Each child was assessed with measures of cognition and psychopathology. Children with Lyme disease had significantly more cognitive and psychiatric disturbances. Cognitive deficits were still found after controlling for anxiety, depression, and fatigue. Lyme disease in children may be accompanied by long-term neuropsychiatric disturbances, resulting in psychosocial and academic impairments. Areas for further study are discussed.

    Cognitive impairment is very common in chronic kidney disease (CKD) and is strongly associated with increased mortality. This review article will discuss the pathophysiology of cognitive impairment in CKD, as well as the effect of dialysis and transplantation on cognitive function. In CKD, uremic toxins, hyperparathyroidism and Klotho deficiency lead to chronic inflammation, endothelial dysfunction and vascular calcifications. This results in an increased burden of cerebrovascular disease in CKD patients, who consistently have more white matter hyperintensities, microbleeds, microinfarctions and cerebral atrophy on magnetic resonance imaging scans. Hemodialysis, although beneficial in terms of uremic toxin clearance, also contributes to cognitive decline by causing rapid fluid and osmotic shifts. Decreasing the dialysate temperature and increasing total dialysis time limits these shifts and helps maintain cognitive function in hemodialysis patients. For many patients, kidney transplantation is the preferred treatment modality, because it reverses the underlying mechanisms causing cognitive impairment in CKD. These positive effects have to be balanced against the possible neurotoxicity of infections and immunosuppressive medications, especially glucocorticosteroids and calcineurin inhibitors. A limited number of studies have addressed the overall effect of transplantation on cognitive function. These have mostly found an improvement after transplantation, but have a limited applicability to daily practice because they have only included relatively young patients. PMID:26479287

    Full Text Available Abstract Background Malnutrition is associated with both structural and functional pathology of the brain. A wide range of cognitive deficits has been reported in malnourished children. Effect of chronic protein energy malnutrition (PEM causing stunting and wasting in children could also affect the ongoing development of higher cognitive processes during childhood (>5 years of age. The present study examined the effect of stunted growth on the rate of development of cognitive processes using neuropsychological measures. Methods Twenty children identified as malnourished and twenty as adequately nourished in the age groups of 5–7 years and 8–10 years were examined. NIMHANS neuropsychological battery for children sensitive to the effects of brain dysfunction and age related improvement was employed. The battery consisted of tests of motor speed, attention, visuospatial ability, executive functions, comprehension and learning and memory Results Development of cognitive processes appeared to be governed by both age and nutritional status. Malnourished children performed poor on tests of attention, working memory, learning and memory and visuospatial ability except on the test of motor speed and coordination. Age related improvement was not observed on tests of design fluency, working memory, visual construction, learning and memory in malnourished children. However, age related improvement was observed on tests of attention, visual perception, and verbal comprehension in malnourished children even though the performance was deficient as compared to the performance level of adequately nourished children. Conclusion Chronic protein energy malnutrition (stunting affects the ongoing development of higher cognitive processes during childhood years rather than merely showing a generalized cognitive impairment. Stunting could result in slowing in the age related improvement in certain and not all higher order cognitive processes and may also result in

    Purpose We investigated the association between cognitive impairment and chronic obstructive pulmonary disease (COPD), taking into account demographic and clinical variables evaluated during routine practice. Patients and methods We performed a post hoc analysis of a cross-sectional study that included subjects with stable COPD. Sociodemographic and clinical information was recorded using the Body mass index, airflow Obstruction, Dyspnea and Exacerbations index and the Charlson comorbidity index. Cognitive performance was studied by the mini-mental state examination, with a score less than 27 indicating clinical impairment. Depressive symptoms, physical activity, and quality of life (EuroQoL-5 dimensions and COPD Assessment Test) were also evaluated. Results The analysis included 940 subjects. The prevalence of cognitive impairment was 39.4%. Multivariate logistic regression models revealed that cognitive impairment was associated with educational level (odds ratio [OR] =0.096, 95% confidence interval [CI] =0.011–0.447) and poorer quality of life measured by the EuroQoL-5 dimensions social tariff (OR =0.967, 95% CI =0.950–0.983). When questionnaires were not included in the analysis, cognitive impairment was associated with educational level (OR =0.063, 95% CI =0.010–0.934), number of exacerbations (OR =11.070, 95% CI =1.450–84.534), Body mass index, airflow Obstruction, Dyspnea and Exacerbations index score (OR =1.261, 95% CI =1.049–1.515), and the Charlson comorbidity index (OR =1.412, 95% CI =1.118–1.783). Conclusion Cognitive impairment is common in COPD and is associated with low educational level, higher disease severity, and increased comorbidity. This could have therapeutic implications for this population. PMID:27042043

The Mini Mental Test score was found to be correlated with age (r=-0.428, hemoglobin (r=0.336, CRP (r=-0.311, and albumin (r=0.336; the Calculation Test score was found to be correlated with LDL cholesterol (r=-0.336; the Praxis Test Score was found to be correlated with duration of CKD (r=-0.204, HDL (r=0.188; and the Visual Memory Test score was found to be correlated with parathormone levels (r=-0.270. We found the CD rate to be higher in patients on HD (50% than on PD (23.3%, p=0.032. CONCLUSION: Our findings suggest that anemia, malnutrition and inflammation play an important role in the development of CD in our patients, and cognitive functions are better preserved in the PD group than the HD group.

  13. An examination of the acute and chronic effects of exercise on cognitive function in older adults

    OpenAIRE

    Joyce, Jennifer

    2013-01-01

    peer-reviewed Research suggests that older adults can experience enhanced cognitive health as a consequence of participation in chronic exercise. However, a dose-response relationship between exercise and cognitive performance has not yet been established which makes the accurate prescription of exercise for cognitive gains difficult. In the search for appropriate exercise guidelines to promote cognitive health in old age research should focus on gaining greater insight into...

    Chronic stress impairs learning and memory in humans and rodents and disrupts long-term potentiation (LTP) in animal models. These effects are associated with structural changes in hippocampal neurons, including reduced dendritic arborization. Unlike the generally reversible effects of chronic stress on adult rat hippocampus, we have previously found that the effects of early-life stress endure and worsen during adulthood, yet the mechanisms for these clinically important sequelae are poorly ...

    Full Text Available Background/Aims: Chronic stress can lead to cognitive impairment. Senescence-accelerated mouse prone 8 (SAMP8 is a naturally occurring animal model that is useful for investigating the neurological mechanisms of Alzheimer's disease. Here we investigated the impact and mechanisms of chronic stress on cognition in male SAMP8 mice. Methods: Male 6-month- old SAMP8 and SAMR1 (senescence-accelerated mouse resistant 1 mice strains were randomly divided into 4 groups. Mice in the unpredictable chronic mild stress (UCMS groups were exposed to diverse stressors for 4 weeks. Then, these mice performed Morris water maze (MWM test to assess the effect of UCMS on learning and memory. To explore the neurological mechanisms of UCMS on cognition in mice, we evaluated changes in the expression of postsynaptic density 95 (PSD95 and synaptophysin (SYN, which are essential proteins for synaptic plasticity. Five mice from each group were randomly chosen for reverse transcription polymerase chain reaction (RT-PCR and western blotting analysis of SYN and PSD95. Results: The Morris water maze experiment revealed that the cognitive ability of the SAMP8 mice decreased with brain aging, and that chronic stress aggravated this cognitive deficit. In addition, chronic stress decreased the mRNA and protein expression of SYN and PSD95 in the hippocampus of the SAMP8 mice; however, the SAMR1 mice were unaffected. Conclusion: Our results demonstrate that decreased cognition and synaptic plasticity are related to aging. Moreover, we show that chronic stress aggravated this cognitive deficit and decreased SYN and PSD95 expression in the SAMP8 mice. Furthermore, the SAMP8 mice were more vulnerable to the detrimental effects of chronic stress on cognition than the SAMR1 mice. Our results suggest that the neurological mechanisms of chronic stress on cognition might be associated with a decrease in hippocampal SYN and PSD95 expression, which is critical for structural synaptic

    Vascular dementia, being the most severe form of vascular cognitive impairment (VCI), is caused by cerebrovascular disease. Whether organophosphorus causes VCI remains unknown. Isocarbophos (0.5 mg/kg per 2 days) was intragastrically administrated to rats for 16 weeks. The structure and function of cerebral arteries were assayed. The learning and memory were evaluated by serial tests of step-down, step-through and morris water maze. Long-term administration of isocarbophos reduced the hippocampal acetylcholinesterase (AChE) activity and acetylcholine (ACh) content but did not alter the plasma AChE activity, and significantly damaged the functions of learning and memory. Moreover, isocarbophos remarkably induced endothelial dysfunction in the middle cerebral artery and the expressions of ICAM-1 and VCAM-1 in the posterior cerebral artery. Morphological analysis by light microscopy and electron microscopy indicated disruptions of the hippocampus and vascular wall in the cerebral arteries from isocarbophos-treated rats. Treatment of isocarbophos injured primary neuronal and astroglial cells isolated from rats. Correlation analysis demonstrated that there was a high correlation between vascular function of cerebral artery and hippocampal AChE activity or ACh content in rats. In conclusion, chronic administration of isocarbophos induces impairments of memory and learning, which is possibly related to cerebral vascular dysfunction. PMID:26818681

    2016-01-01

    The cognitive mechanisms underpinning chronic tinnitus (CT; phantom auditory perceptions) are underexplored but may reflect a failure to switch attention away from a tinnitus sound. Here, we investigated a range of components that influence the ability to switch attention, including cognitive control, inhibition, working memory and mood, on the presence and severity of CT. Our participants with tinnitus showed significant impairments in cognitive control and inhibition as well as lower levels of emotional well-being, compared to healthy-hearing participants. Moreover, the subjective cognitive complaints of tinnitus participants correlated with their emotional well-being whereas complaints in healthy participants correlated with objective cognitive functioning. Combined, cognitive control and depressive symptoms correctly classified 67% of participants. These results demonstrate the core role of cognition in CT. They also provide the foundations for a neurocognitive account of the maintenance of tinnitus, involving impaired interactions between the neurocognitive networks underpinning attention-switching and mood.

    Exposure to toxic industrial substances has been a topic of increasing concern to environmentalists, government agencies, industrial engineers, and medical specialists. Our study focuses on the psychologic symptom responses of a community to perceived long-term exposure to toxic waste products. We compared their symptom clusters, as shown by their responses to questions on the Hopkins Symptom Checklist-90 Item (SCL-90) and the Social Adjustment Scale (SAS), with symptom levels of normal and depressed subjects. Issues of media coverage, litigation, and potential for compensation complicate the psychiatric epidemiology of the subject.

    International Nuclear Information System (INIS)

    A variety of neuroendocrine disturbances are observed following treatment with external radiation therapy when the hypothalamic-pituitary axis (HPA) is included in the treatment field. Radiation-induced abnormalities are generally dose dependent and may develop many years after irradiation. Growth hormone deficiency and premature sexual development can occur following doses as low as 18 Gy fractionated radiation and are the most common neuroendocrine problems noted in children. Deficiency of gonadotropins, thyroid stimulating hormone, and adrenocorticotropin are seen primarily in individuals treated with > 40 Gy HPA irradiation. Hyperprolactinemia can be seen following high-dose radiotherapy (> 40 Gy), especially among young women. Most neuroendocrine disturbances that develop as a result of HPA irradiation are treatable; patients at risk require long-term endocrine follow-up

  17. Cognitive Dysfunction in Chronic Fatigue Syndrome: a Review of Recent Evidence.

    Science.gov (United States)

    Cvejic, Erin; Birch, Rachael C; Vollmer-Conna, Uté

    2016-05-01

    Cognitive difficulties represent a common and debilitating feature of the enigmatic chronic fatigue syndrome (CFS). These difficulties manifest as self-reported problems with attention, memory, and concentration and present objectively as slowed information processing speed particularly on complex tasks requiring sustained attention. The mechanisms underlying cognitive dysfunction remain to be established; however, alterations in autonomic nervous system activity and cerebral blood flow have been proposed as possibilities. Heterogeneity in the experience of cognitive impairment, as well as differences in the methods utilised to quantify dysfunction, may contribute to the difficulties in establishing plausible biological underpinnings. The development of a brief neurocognitive battery specifically tailored to CFS and adoption by the international research community would be beneficial in establishing a profile of cognitive dysfunction. This could also provide better insights into the underlying biological mechanisms of cognitive dysfunction in CFS and enhance the development of targeted treatments. PMID:27032787

    Full Text Available Background and aims: Depression and cognitive disorders were reported more frequently in patients with diabetes mellitus (DM. Our aim was to analyze the association of cognitive disorders and depression association with chronic complications of DM in a group of Romanian patients. Materials and methods: The data was analyzed from 181 patients, with a mean age of 58,3 years to whom we applied the MMSE (Mini- Mental State Examination and MADRS (Montgomery-Asberg Depression Rating Scale questionnaires. We also analyzed the presence of chronic DM complications, HbA1c and lipid profile. Results: Most patients with type 2 diabetes mellitus (T2DM had mild cognitive impairment (92%, more common in the age group 50-59 years. Chronic macrovascular complications were present in 74.58%, while chronic microvascular complications were present in 61.87% of patients with T2DM who associated mild and moderate cognitive impairment (p = 0.013. The most common form of depression was mild depression (90.2%, present in most patients with DM, regardless of progression and type of treatment. MADRS depression test scores were statistically significant correlated with the presence of peripheral artery disease - PAD (p <0.001, ischemic heart disease - IHD (p <0.001 and chronic kidney disease - CKD (p =0.05. We did not find a statistically significant correlation with HbA1c and serum lipid values (p˃0,05. Conclusion: Chronic diabetes macrovascular complications (PAD, IHD and CKD were more frequently associated with cognitive disorders and depression in patients with T2DM independent of the degree of metabolic control.

    Chronic pain is frequently experienced in adolescents; it affects functionality and requires interventions to decrease the impairments caused by pain. Cognitive behavioral therapy (CBT) has been analyzed in numerous studies that evaluated its effects on reducing the different types of chronic pain in children and adolescents. Interestingly, the outcome of CBT was initially focused on pain intensity, but, because there is no correspondence between children's pain intensity and level of disability, the ability to participate in school and social and recreational activities have been the primary focus of recent studies. There are innovative methods of CBT (such as the third generation of CBT) with and without the use of technology that facilitates the availability of this psychological treatment to adolescents with chronic pain, optimizing its accessibility and comprehensiveness, and maintaining its effectiveness. In the future, specific types of CBT could be specific to the diagnosis of chronic pain in the adolescent, sociodemographics, and other unique features. Parents of children with chronic pain are usually included in these programs, either as coaches in the intervention or as recipients of psychological therapies (including CBT) to optimize benefits. CBT has no adverse effect on chronic pain in adolescents, and there is no literature that makes reference to the effectiveness of CBT in preventing chronic pain in adolescents. A review of the role of CBT in chronic pain in adolescents via a PubMed database search was performed to identify the role of CBT in the management of chronic pain in adolescents.

    Since the introduction of behavioral medicine in the early 70s, cognitive-behavioral treatment interventions for chronic pain have expanded considerably. It is now well established that these interventions are effective in reducing the enormous suffering that patients with chronic pain have to bear. In addition, these interventions have potential economic benefits in that they appear to be cost-effective as well. Despite these achievements, there is still room for improvement. First, there is a substantial proportion of patients who do not appear to benefit from treatment interventions available. Second, although the effect sizes of most cognitive-behavioral treatments for chronic pain are comparable to those in psychopathology, they are quite modest. Third, there is little evidence for differential outcomes for different treatment methods. Fourth, there still is relatively little known about the specific biobehavioral mechanisms that lead to chronic pain and pain disability. One direction is to better match treatment programs to patients' characteristics. This can be done according to an "Aptitude X Treatment Interaction" framework, or from the perspective of the Moderator-Mediator distinction. In this introduction to the special series on what works for whom in cognitive-behavioral treatments for chronic pain, we review existing knowledge concerning both moderating and mediating variables in cognitive-behavioral treatments for chronic pain. We further argue in favor of theory-driven research as the only way to define specific a priori hypotheses about which patient-treatment interactions to expect. We also argue that replicated single-participant studies, with appropriate statistics, are likely to enhance new developments in this clinical research area.

    Full Text Available Adolescents with traumatic brain injury (TBI typically demonstrate good recovery of previously acquired skills. However, higher-order and later emergent cognitive functions are often impaired and linked to poor outcomes in academic and social/behavioral domains. Few control trials exist that test cognitive treatment effectiveness at chronic recovery stages. The current pilot study compared the effects of two forms of cognitive training, gist reasoning (top-down versus rote memory learning (bottom-up, on ability to abstract meanings, recall facts, and utilize core executive functions (i.e., working memory, inhibition in 20 adolescents (ages 12-20 who were six months or longer post-TBI. Participants completed eight 45-minute sessions over one month. After training, the gist reasoning group (n = 10 exhibited significant improvement in ability to abstract meanings and increased fact recall. This group also showed significant generalizations to untrained executive functions of working memory and inhibition. The memory training group (n = 10 failed to show significant gains in ability to abstract meaning or on other untrained specialized executive functions, although improved fact recall approached significance. These preliminary results suggest that relatively short-term training (6 hours utilizing a top-down reasoning approach is more effective than a bottom-up rote learning approach in achieving gains in higher-order cognitive abilities in adolescents at chronic stages of TBI. These findings need to be replicated in a larger study; nonetheless, the preliminary data suggest that traditional cognitive intervention schedules need to extend to later-stage training opportunities. Chronic-stage, higher-order cognitive trainings may serve to elevate levels of cognitive performance in adolescents with TBI.

    During the last few years, the time spent in front of various screens, including TV sets, video games, smartphones and computers, has dramatically increased. Numerous studies show, with a remarkable consistency, that this trend has a strong negative influence on the cognitive development of children and teenagers. The affected fields include, in particular, scholastic achievement, language, attention, sleep and aggression. We believe that this often disregarded - not to say denied - problem should now be considered a major public health issue. Primary care physicians should inform parents and children about this issue to support efficient prevention. PMID:22609414

    Full Text Available Both vitamin D deficiency and cognitive impairment are common in patients with chronic kidney disease (CKD. Vitamin D exerts neuroprotective and regulatory roles in the central nervous system. Hypovitaminosis D has been associated with muscle weakness and bone loss, cardiovascular diseases (hypertension, diabetes and hyperlipidemia, inflammation, oxidative stress, immune suppression and neurocognitive impairment. The combination of hypovitaminosis D and CKD can be even more debilitating, as cognitive impairment can develop and progress through vitamin D-associated and CKD-dependent/independent processes, leading to significant morbidity and mortality. Although an increasingly recognized comorbidity in CKD, cognitive impairment remains underdiagnosed and often undermanaged. Given the association of cognitive decline and hypovitaminosis D and their deleterious effects in CKD patients, determination of vitamin D status and when appropriate, supplementation, in conjunction with neuropsychological screening, should be considered integral to the clinical care of the CKD population.

    Full Text Available "n  "n Objective:Because of on-call responsibilities, many medical residents are subjected to chronic partial sleep deprivation, a form of sleep restriction whereby individuals have chronic patterns of insufficient sleep. It is unclear whether deterioration in cognitive processing skills due to chronic partial sleep deprivation among medical residents would influence educational exposure or patient safety. Method: Twenty-six medical residents were recruited to participate in the study. Participants wore an Actigraph over a period of 5 consecutive days and nights so their sleep pattern could be recorded. Thirteen participants worked on services that forced chronic partial sleep deprivation (<6 hours of sleep per 24h for 5 consecutive days and nights. The other thirteen residents worked on services that permitted regular and adequate sleep patterns. Following the 5-day sleep monitoring period, the participants completed the three following cognitive tasks: (a the Wisconsin Card Sorting Test (WCST to assess abstract reasoning and prefrontal cortex performance; (b the Time Perception Task (TPT to assess time estimation and time reproduction skills; and (c the Iowa Gambling Task (IGT to assess decision-making ability. "nResults: The results of independent samples t-tests found no significant differences between the group who was chronically sleep deprived and the group who rested adequately (all ps > .05. "nConclusion: These results may have emerged for several possible reasons: (a chronic partial sleep deprivation may have a lesser impact on prefrontal cortex function than on other cognitive functions; (b fairly modest chronic sleep restriction may be less harmful than acute and more significant sleep restriction; or (c our research may have suffered from poor statistical power. Future research is recommended.

  1. Caught in the thickness of brain fog: exploring the cognitive symptoms of Chronic Fatigue Syndrome

    Anthony James Ocon

    2013-04-01

    Full Text Available Chronic Fatigue Syndrome (CFS is defined as greater than 6 months of persistent fatigue that is experienced physically and cognitively. The cognitive symptoms are generally thought to be a mild cognitive impairment, but individuals with CFS subjectively describe them as brain fog. The impairment is not fully understood and often is described as slow thinking, difficulty focusing, confusion, lack of concentration, forgetfulness, or a haziness in thought processes. Causes of brain fog and mild cognitive impairment have been investigated. Possible physiological correlates may be due to the effects of chronic orthostatic intolerance in the form of the Postural Tachycardia Syndrome and decreases in cerebral blood flow. In addition, fMRI studies suggest that individuals with CFS may require increased cortical and subcortical brain activation to complete difficult mental tasks. Furthermore, neurocognitive testing in CFS has demonstrated deficits in speed and efficiency of information processing, attention, concentration, and working memory. The cognitive impairments are then perceived as an exaggerated mental fatigue. As a whole, this is experienced by those with CFS as brain fog and may be viewed as the interaction of physiological, cognitive, and perceptual factors. Thus, the cognitive symptoms of CFS may be due to altered cerebral blood flow activation and regulation that are exacerbated by a stressor, such as orthostasis or a difficult mental task, resulting in the decreased ability to readily process information, which is then perceived as fatiguing and experienced as brain fog. Future research looks to further explore these interactions, how they produce cognitive impairments, and explain the perception of brain fog from a mechanistic standpoint.

    2013-08-01

    Full Text Available Limited scientific evidence suggests that physical activity is directly related to cognitive performance in patients with chronic fatigue syndrome (CFS. To date, no other study has examined the direct relationship between cognitive performance and physical fitness in these patients. This study examined whether cognitive performance and physical fitness are associated in female patients with CFS and investigated the association between cognitive performance and physical activity level (PAL in the same study sample. We hypothesized that patients who performed better on cognitive tasks would show increased PALs and better performance on physical tests. The study included 31 women with CFS and 13 healthy inactive women. Participants first completed three cognitive tests. Afterward, they undertook a test to determine their maximal handgrip strength, performed a bicycle ergometer test, and were provided with an activity monitor. In patients with CFS, lower peak oxygen uptake and peak heart rate were associated with slower psychomotor speed (p < 0.05. Maximal handgrip strength was correlated with working memory performance (p < 0.05. Both choice and simple reaction time were lower in patients with CFS relative to healthy controls (p < 0.05 and p < 0.001, respectively. In conclusion, physical fitness, but not PAL, is associated with cognitive performance in female patients with CFS.

    Over the past decade, the prevalence of chronic kidney disease (CKD) has reached epidemic proportions. The search for novel pharmacological treatment for CKD has become an area of intensive clinical research. l-Carnitine, considered as the "gatekeeper" responsible for admitting long chain fatty acids into cell mitochondria. l-Carnitine synthesis and turnover are regulated mainly by the kidney and its levels inversely correlate with serum creatinine of normal subjects and CKD patients. Previous studies showed that l-carnitine administration to elderly people is improving and preserving cognitive function. As yet, there are no clinical intervention studies that investigated the effect of l-carnitine administration on cognitive impairment evidenced in CKD patients. Thus, we aimed to investigate the effects of l-carnitine treatment on renal function and on the cognitive performance in a rat model of progressive CKD. To assess the role of l-carnitine on CKD condition, we estimated the renal function and cognitive abilities in a CKD rat model. We found that all CKD animals exhibited renal function deterioration, as indicated by elevated serum creatinine, BUN, and ample histopathological abnormalities. l-Carnitine treatment of CKD rats significantly reduced serum creatinine and BUN, attenuated renal hypertrophy and decreased renal tissue damage. In addition, in the two way shuttle avoidance learning, CKD animals showed cognitive impairment which recovered by the administration of l-carnitine. We conclude that in a rat model of CKD, l-carnitine administration significantly improved cognitive and renal functions.

    Adverse childhood experiences can show lasting effects on physical and mental health. Major questions surround how children overcome adverse circumstances to prevent negative outcomes. A key factor determining resilience is likely to be cognitive interpretation (how children interpret the world around them). The cognitive interpretations of 1025 school children aged 10-12 years in a rural, socioeconomically disadvantaged area of South Africa were examined using the Cognitive Triad Inventory for Children (CTI-C). These were examined in relation to psychological functioning and perceptions of the school environment. Those with more positive cognitive interpretations had better psychological functioning on scales of depression, anxiety, somatization and sequelae of potentially traumatic events. Children with more negative cognitions viewed the school-environment more negatively. Children living in poverty in rural South Africa experience considerable adversity and those with negative cognitions are at risk for psychological problems. Targeting children's cognitive interpretations may be a possible area for intervention. PMID:26994348

    Cognitive deficits are a core feature of schizophrenia and we examined the cognitive profile of first-episode and chronic schizophrenia in a Chinese Han population using the MATRICS Consensus Cognitive Battery (MCCB). We recruited 79 first-episode drug-naïve (FEDN) schizophrenia, 132 chronic medicated schizophrenia inpatients and 124 healthy controls. We assessed patient psychopathology using the Positive and Negative Syndrome Scale (PANSS). MCCB total score (pEmotional Intelligence Test (MSCEIT) were significantly higher in FEDN than in chronic patients (all pMultiple regression analysis confirmed that in FEDN and chronic patients, total score and negative symptom of PANSS were independent contributors to MCCB total score, respectively. Our results not only demonstrate the applicability of the MCCB as a sensitive measure of cognitive impairment for schizophrenia patients in a Chinese Han population, but also suggest that the compromised cognition is present in the early stage of schizophrenia, some of which could be more severe in the chronic stage of illness.

    Full Text Available Few investigators have studied cognition over time in adults with heart failure (HF. A battery of neuropsychological tests was administered to 279 adults with chronic systolic or diastolic HF at baseline, three and six months. Growth mixture modeling (GMM was used to model the measure anticipated to be most sensitive, the digit symbol substitution task (DSST. We describe how and why the DSST patterns change over time. Other measures of cognition were examined to identify consistency with the DSST patterns. The sample was predominantly male (63.2%, Caucasian (62.7%, mean age 62 years. The best fit GMM revealed two trajectories of DSST scores: Average processing speed group (40.5% and Below Average processing speed (59.9%. Neither group changed significantly over the six month study. Other measures of cognition were consistent with the DSST patterns. Factors significantly associated with increased odds of being in the Below Average processing speed group included older age, male gender, Non-Caucasian race, less education, higher ejection fraction, high comorbid burden, excessive daytime sleepiness, and higher BMI. As some of the factors related to cognitive impairment are modifiable, research is needed to identify interventions to preserve and improve cognition in these patients.

    Full Text Available The precise relationship between sleep and physical and mental functioning in chronic fatigue syndrome (CFS has not been examined directly, nor has the impact of daytime napping. This study aimed to examine self-reported sleep in patients with CFS and explore whether sleep quality and daytime napping, specific patient characteristics (gender, illness length and levels of anxiety and depression, predicted daytime fatigue severity, levels of daytime sleepiness and cognitive functioning, all key dimensions of the illness experience.118 adults meeting the 1994 CDC case criteria for CFS completed a standardised sleep diary over 14 days. Momentary functional assessments of fatigue, sleepiness, cognition and mood were completed by patients as part of usual care. Levels of daytime functioning and disability were quantified using symptom assessment tools, measuring fatigue (Chalder Fatigue Scale, sleepiness (Epworth Sleepiness Scale, cognitive functioning (Trail Making Test, Cognitive Failures Questionnaire, and mood (Hospital Anxiety and Depression Scale.Hierarchical Regressions demonstrated that a shorter time since diagnosis, higher depression and longer wake time after sleep onset predicted 23.4% of the variance in fatigue severity (p <.001. Being male, higher depression and more afternoon naps predicted 25.6% of the variance in objective cognitive dysfunction (p <.001. Higher anxiety and depression and morning napping predicted 32.2% of the variance in subjective cognitive dysfunction (p <.001. When patients were classified into groups of mild and moderate sleepiness, those with longer daytime naps, those who mainly napped in the afternoon, and those with higher levels of anxiety, were more likely to be in the moderately sleepy group.Napping, particularly in the afternoon is associated with poorer cognitive functioning and more daytime sleepiness in CFS. These findings have clinical implications for symptom management strategies.

  17. Effects of chronic variable stress on cognition and Bace1 expression among wild-type mice.

    2016-01-01

    Stressful life events, activation of the hypothalamic-pituitary-adrenal (HPA) axis and glucocorticoids are now thought to have a role in the development of several neurodegenerative and psychiatric disorders including Alzheimer's disease (AD) through mechanisms that may include exacerbation of cognitive impairment, neuronal loss, and beta-amyloid (Aβ) and tau neuropathology. In the current study, we use a wild-type mouse model to demonstrate that chronic variable stress impairs cognitive function and that aged mice are particularly susceptible. We also find that stress exposure is associated with a 1.5- to 2-fold increase in the expression of Bace1 in the hippocampus of young adult mice and the hippocampus, prefrontal cortex and amygdala of aged mice. Further, the increased expression of Bace1 was associated with decreased methylation of several CpGs in the Bace1 promoter region. In a second series of experiments, exposure to environmental enrichment (EE) prevented the stress-related changes in cognition, gene expression and DNA methylation. Together, these findings re-affirm the adverse effects of stress on cognition and further suggest that aged individuals are especially susceptible. In addition, demonstrating that chronic stress results in decreased DNA methylation and increased expression of Bace1 in the brain may provide a novel link between stress, Aβ pathology and AD. Finally, understanding the mechanisms by which EE prevented the effects of stress on cognition and Bace1 expression will be an important area of future study that may provide insights into novel approaches to the treatment of AD.

    The diagnosis of Attention Deficit Hyperactivity Disorder (ADHD) often results in chronic treatment with psychostimulants such as methylphenidate (MPH, Ritalin®). With increases in misdiagnosis of ADHD, children may be inappropriately exposed to chronic psychostimulant treatment during development. The aim of this study was to assess the effect of chronic Ritalin treatment on cognitive and neural development in misdiagnosed “normal” (Wistar Kyoto, WKY) rats and in Spontaneously Hypertensive R...

  19. Neuroimaging assessment of early and late neurobiological sequelae of traumatic brain injury: implications for CTE

    2015-09-01

    Full Text Available Traumatic brain injury (TBI has been increasingly accepted as a major external risk factor for neurodegenerative morbidity and mortality. Recent evidence indicates that the resultant chronic neurobiological sequelae following head trauma may, at least in part, contribute to a pathologically distinct disease known as Chronic Traumatic Encephalopathy (CTE. The clinical manifestation of CTE is variable, but the symptoms of this progressive disease include impaired memory and cognition, affective disorders (i.e., impulsivity, aggression, depression, suicidality, etc., and diminished motor control. Notably, mounting evidence suggests that the pathology contributing to CTE may be caused by repetitive exposure to subconcussive hits to the head, even in those with no history of a clinically evident head injury. Given the millions of athletes and military personnel with potential exposure to repetitive subconcussive insults and TBI, CTE represents an important public health issue. However, the incidence rates and pathological mechanisms are still largely unknown, primarily due to the fact that there is no in vivo diagnostic tool. The primary objective of this manuscript is to address this limitation and discuss potential neuroimaging modalities that may be capable of diagnosing CTE in vivo through the detection of tau and other known pathological features. Additionally, we will discuss the challenges of TBI research, outline the known pathology of CTE (with an emphasis on Tau, review current neuroimaging modalities to assess the potential routes for in vivo diagnosis, and discuss the future directions of CTE research.

    Chronic psychosocial stress is an important environmental risk factor of psychiatric diseases such as schizophrenia. Social defeat in rodents has been shown to be associated with maladaptive cellular and behavioral consequences including cognitive impairments. Although gene expression changes upon psychosocial stress have been described, a comprehensive transcriptome profiling study at the global level in precisely defined hippocampal subregions which are associated with learning has been lacking. In this study, we exposed adult C57Bl/6N mice for 3 weeks to "resident-intruder" paradigm and combined laser capture microdissection with microarray analyses to identify transcriptomic signatures of chronic psychosocial stress in dentate gyrus and CA3 subregion of the dorsal hippocampus. At the individual transcript level, we detected subregion specific stress responses whereas gene set enrichment analyses (GSEA) identified several common pathways upregulated upon chronic psychosocial stress related to proteasomal function and energy supply. Behavioral profiling revealed stress-associated impairments most prominent in fear memory formation which was prevented by chronic lithium treatment. Thus, we again microdissected the CA3 region and performed global transcriptome analysis to search for molecular signatures altered by lithium treatment in stressed animals. By combining GSEA with unsupervised clustering, we detected pathways that are regulated by stress and lithium in the CA3 region of the hippocampus including proteasomal components, oxidative phosphorylation, and anti-oxidative mechanisms. Our study thus provides insight into hidden molecular phenotypes of chronic psychosocial stress and lithium treatment and proves a beneficial role for lithium treatment as an agent attenuating negative effects of psychosocial stress on cognition.

    Subcortical ischemic vascular dementia (SIVD) caused by chronic cerebral hypoperfusion develops with progressive white matter and cognitive impairments, yet no effective therapy is available. We investigated the temporal effects of minocycline on an experimental SIVD exerted by right unilateral common carotid arteries occlusion (rUCCAO). Minocycline treated at the early stage (day 0-3), but not the late stage after rUCCAO (day 4-32) alleviated the white matter and cognitive impairments, and promoted remyelination. The actions of minocycline may not involve the inhibition of microglia activation, based on the effects after the application of a microglial activation inhibitor, macrophage migration inhibitory factor, and co-treatment with lipopolysaccharides. Furthermore, minocycline treatment at the early stage promoted the proliferation of oligodendrocyte progenitor cells (OPCs) in subventricular zone, increased OPC number and alleviated apoptosis of mature oligodendrocytes in white matter. In vitro, minocycline promoted OPC proliferation and increased the percentage of OPCs in S and G2/M phases. We provided direct evidence that early treatment is critical for minocycline to alleviate white matter and cognitive impairments after chronic cerebral hypoperfusion, which may be due to its robust effects on OPC proliferation and mature oligodendrocyte loss. So, early therapeutic time window may be crucial for its application in SIVD.

    Growing clinical evidence suggests that persistent psychosis which occurs in methamphetamine users is closely related to schizophrenia. However, preclinical studies in animal models have focussed on psychosis-related behaviours following methamphetamine, and less work has been done to assess endophenotypes relevant to other deficits observed in schizophrenia. Altered social behaviour is a feature of both the negative symptoms and cognitive deficits in schizophrenia, and significantly impacts patient functioning. We recently found that brain-derived neurotrophic factor (BDNF) heterozygous mice show disrupted sensitization to methamphetamine, supporting other work suggesting an important role of this neurotrophin in the pathophysiology of psychosis and the neuronal response to stimulant drugs. In the current study, we assessed social and cognitive behaviours in methamphetamine-treated BDNF heterozygous mice and wildtype littermate controls. Following chronic methamphetamine exposure male wildtype mice showed a 50% reduction in social novelty preference. Vehicle-treated male BDNF heterozygous mice showed a similar impairment in social novelty preference, with a trend for no further disruption by methamphetamine exposure. Female mice were unaffected in this task, and no groups showed any changes in sociability or short-term spatial memory. These findings suggest that chronic methamphetamine alters behaviour relevant to disruption of social cognition in schizophrenia, supporting other studies which demonstrate a close resemblance between persistent methamphetamine psychosis and schizophrenia. Together these findings suggest that dynamic regulation of BDNF signalling is necessary to mediate the effects of methamphetamine on behaviours relevant to schizophrenia.

    This thesis explores some of the endocrine sequelae following irradiation and cytotoxic chemotherapy in childhood which to date have not been clearly defined. Greater understanding of these sequelae will aid the management of survivors of childhood malignancy, who by virtue of improved management of the primary disease are increasing in number and complexity. The majority of this thesis involves children who have received cranial irradiation for a brain tumour distant from the hypothalamic-pituitary axis, but endocrine sequelae in children who have undergone total body irradiation and bone marrow transplantation for haematological malignancies have also been studied.

    Mental illnesses are frequent co-morbid conditions in chronic systemic diseases. High incidences of depression, anxiety and cognitive impairment complicate cardiovascular and metabolic disorders such as hypertension and diabetes mellitus. Lifestyle changes including regular exercise have been advocated to reduce blood pressure and improve glycaemic control. The purpose of this project was to evaluate the effect of physical training on the most prevalent corollary psychiatric problems in patients with chronic organic ailments. This longitudinal study assessed the mental health of hypertensive (age: 57 ± 8 years) and/or diabetic (age: 53 ± 8 years) patients using mini-mental state examination, Beck's depression inventory, Beck's anxiety inventory and self-reporting questionnaire-20 before and after a 3-month supervised resistance and aerobic exercise programme comprising structured physical activity three times a week. Clinically relevant improvement was observed in the Beck's depression inventory and Beck's anxiety inventory scores following the 12-week training (61%, p = 0.001, and 53%, p = 0.02, respectively). Even though statistically not significant (p = 0.398), the cognitive performance of this relatively young patient population also benefited from the programme. These results demonstrate positive effects of active lifestyle on non-psychotic mental disorders in patients with chronic systemic diseases, recommending exercise as an alternative treatment option.

    Good sleep is necessary for optimal health, especially for mental health. Insomnia, sleep deprivation will make your ability to learn and memory impaired. Nevertheless, the underlying pathophysiological mechanism of sleep disorders-induced cognitive decline is still largely unknown. In this study, the sleep deprivation of animal model was induced by chronical sleep interruption (CSI), the behavioral tests, biochemical index determinations, and a liquid chromatography-mass spectrometry (LC-MS) based serum metabolic profiling analysis were performed to explore the effects of CSI on cognitive function and the underlying mechanisms. After 14-days CSI, the cognitive function of the mice was evaluated by new objects preference (NOP) task and temporal order judgment (TOJ) task. Serum corticosterone (CORT), and brain Malondialdehyde (MDA), Superoxide Dismutase (SOD), and Catalase (CAT) levels were determined by ELISA kits. Data were analyzed by Principal Component Analysis (PCA), Partial Least Squares project to latent structures-Discriminant Analysis (PLS-DA), and Student's t-test. We found that the cognitive function of the mice was significantly affected by CSI. Besides, levels of CORT and MDA were higher, and SOD and CAT were lower in CSI mice than those of control. Obvious body weight loss of CSI mice was also observed. Thirteen potential serum biomarkers including choline, valine, uric acid, allantoic acid, carnitines, and retinoids were identified. Affected metabolic pathways involve metabolism of purine, retinoid, lipids, and amino acid. These results showed that CSI can damage the cognitive performance notably. The cognitive decline may ascribe to excessive oxidative stress and a series of disturbed metabolic pathways. PMID:26747207

    Chronic cerebral hypoperfusion (CCH) induces cognitive impairment, but the compensative mechanism of cerebral blood flow (CBF) is not fully understood. The present study mainly investigated dynamic changes in CBF, angiogenesis, and cellular pathology in the cortex, the striatum, and the cerebellum, and also studied cognitive impairment of rats induced by bilateral common carotid artery occlusion (BCCAO). Magnetic resonance imaging (MRI) techniques, immunochemistry, and Morris water maze were employed to the study. The CBF of the cortex, striatum, and cerebellum dramatically decreased after right common carotid artery occlusion (RCCAO), and remained lower level at 2 weeks after BCCAO. It returned to the sham level from 3 to 6 weeks companied by the dilation of vertebral arteries after BCCAO. The number of microvessels declined at 2, 3, and 4 weeks but increased at 6 weeks after BCCAO. Neuronal degeneration occurred in the cortex and striatum from 2 to 6 weeks, but the number of glial cells dramatically increased at 4 weeks after BCCAO. Cognitive impairment of ischemic rats was directly related to ischemic duration. Our results suggest that CCH induces a compensative mechanism attempting to maintain optimal CBF to the brain. However, this limited compensation cannot prevent neuronal loss and cognitive impairment after permanent ischemia. PMID:25853908

    An instrumental step in assessing the validity of animal models of chronic cognitive disorders is to document disease-related deficits in learning/memory capacity. The water maze (WM) is a popular paradigm because of its low cost, relatively simple protocol and short procedure time. Despite being broadly accepted as a spatial learning task, inference of generalized, bona fide "cognitive" dysfunction can be challenging because task accomplishment is also reliant on non-cognitive processes. We review theoretical background, testing procedures, confounding factors, as well as approaches to data analysis and interpretation. We also describe an extended protocol that has proven useful in detecting early performance deficits in murine models of neuropsychiatric lupus and Alzheimer's disease. Lastly, we highlight the need for standardization of inferential criteria on "cognitive" dysfunction in experimental rodents and exclusion of preparations of a limited scientific merit. A deeper appreciation for the multifactorial nature of performance in WM may also help to reveal other deficits that herald the onset of neurodegenerative brain disorders. PMID:27229758

    Cognitive impairments, including dementia, can present as first symptoms at the acute stage, and/or as sequelae in the chronic stages, in some patients with bacterial meningitis (BM) or encephalitides. BM and encephalitides are lifethreatening neurological emergencies, and early recognition, efficient decision-making, and rapid commencement of therapy can be lifesaving. Empirical therapy should be initiated promptly whenever BM or encephalitides are a probable diagnosis. In this article cognitive impairments, including dementia, presenting in patients with BM, Herpes simplex virus encephalitis (HSVE), Human herpesvirus-6 (HHV-6) encephalitis, and Anti N-methyl-d-aspartate (NMDA) receptor encephalitis are reviewed. In the above mentioned diseases, cognitive impairment without fever might be observed at the time of disease onset. cognitive impairment has been also noted in some aged or immunocompromised patients at the onset of BM. Immediate memory disturbance as one of the first symptoms of HHV-6 encephalitis presented in 74% of patients with this disease. Cognitive impairment, including dementia as sequela, was also found in 10-27% of patients with BM, 54-69% of patients with HSVE, 33% of HHV-6 encephalitis patients, and 39% of patients with anti-NMDA receptor encephalitis. Suitable therapeutic management of these diseases at the acute stage is thus required in order to avoid these sequelae. PMID:27056850

    The prefrontal cortex (PFC) provides top-down regulation of behavior, cognition, and emotion, including spatial working memory. However, these PFC abilities are greatly impaired by exposure to acute or chronic stress. Chronic stress exposure in rats induces atrophy of PFC dendrites and spines that correlates with working memory impairment. As similar PFC grey matter loss appears to occur in mental illness, the mechanisms underlying these changes need to be better understood. Acute stress expo...

    Nicotine, the major specific alkaloid in tobacco smoke, exhibits widespread pharmacological effects and may contribute to deterioration in behaviour. The present study thus examined the effects of its chronic administration on some cognitive and mood associated behaviours. Adult rats weighing between 150 and 200g were randomly divided into 4 groups each of 5 females and 5 males. Three groups were administered graded doses of nicotine at 0.25, 2 and 4mg/kg body weight via subcutaneous injections. One group served as control and received normal saline (vehicle for nicotine). Behavioural tests were performed using the Y-maze, elevated-plus maze (EPM) and tail suspension tests (TST) at various time points. Nicotine produced no significant effect in spontaneous alternation on Y-maze, nor on six parameters scored on EPM (open arm entries, time spent in open arms, time per open arm entries, open/closed arm quotient, closed arm entries, and total arm entries), and also no significant effect on immobility time in TST. This lack of effects was observed to be independent of sex and dose administered. The study shows that nicotine does not produce long-term changes in some cognitive and mood associated behaviours, thus suggesting it could be well tolerated even following chronic administration.

    The purpose of this pilot study is to evaluate the feasibility of a cognitive-behavioural training program for adolescents with chronic pain irrespective of pain localisation. A secondary aim was to give an impression of the effect of the program on pain and quality of life. Eight adolescents (14-18 years) with chronic non-organic pain recruited from the general population (and their parents) participated in this pilot study. The intervention included five group meetings alternated with four telephone contacts (during the self-management weeks) over a period of 9 weeks. The training aimed to change pain behaviour through pain education, relaxation strategies, problem-solving techniques, assertiveness training, cognitive restructuring and by stimulating the adolescent's physical activity level. The training further addresses the social context of pain by inviting parents to attend two meetings for the parents only, and by asking the adolescents to bring a peer to one of the meetings. Adolescents and their parents were positive about the program. Adolescents felt they were more in control of their pain and parents valued the support they experienced in helping their children to master the pain. The training was considered to be feasible in daily life. Further, the preliminary data showed an effect on pain and quality of life in the expected direction. The results underline the need for a definitive study with a larger sample size and a random controlled design. PMID:16257616

    The present study established a rat model of chronic intermittent hypoxia (CIH) to simulate obstructive sleep apnea syndrome. CIH rats were evaluated for cognitive function using the Morris water maze, and neuronal pathology in the hippocampus was observed using hematoxylin-eosin staining. In addition, hippocampal choline acetyl transferase (ChAT) and nicotinic acetylcholine receptor (nAChR) expression was determined by immunohistochemistry. Our results revealed necrotic hippocampal neurons, decreased ChAT and nAChR expression, as well as cognitive impairment in CIH rats. These results suggest that hippocampal neuronal necrosis and decreased cholinergic activity may be involved in CIH-induced cognitive impairment in rats.

Research has shown that psychosocial factors such as anxiety and depression as well as the symptoms of the illness, have a significant impact on the quality of life of people with ME/CFS. In addition, individuals may suffer from deficits in memory and concentration. This study set out to explore the relationships between variables which have been found to contribute to cognitive performance, as measured by prospective and retrospective memory, and cognitive failures. Methods: Eighty-seven people with ME/CFS answered questionnaires measuring fatigue, depression, anxiety, social support, and general self-efficacy. These were used in a correlational design (multiple regression to predict cognitive function (self-ratings on prospective and retrospective memory, and cognitive failures. Results: Our study found that fatigue, depression, and general self-efficacy were directly associated with cognitive failures and retrospective (but not prospective memory. Conclusion: Although it was not possible in this study to determine the cause of the deficits, the literature in this area leads us to suggest that although the pathophysiological mechanisms of ME/CFS are unclear, abnormalities in the immune system, including proinflammatory cytokines, can lead to significant impairments in cognition. We suggest that fatigue and depression may be a result of the neurobiological effects of ME/CFS and in addition, that the neurobiological effects of the illness

    The effects of chronic and repeated radiofrequency electromagnetic radiation (RFEMR) exposure on spatial cognition and hippocampal architecture were investigated in prepubescent rats. Four weeks old male Wistar rats were exposed to RF-EMR (900 MHz; SAR-1.15 W/kg with peak power density of 146.60 μW/cm(2)) for 1 h/day, for 28 days. Followed by this, spatial cognition was evaluated by Morris water maze test. To evaluate the hippocampal morphology; H&E staining, cresyl violet staining, and Golgi-Cox staining were performed on hippocampal sections. CA3 pyramidal neuron morphology and surviving neuron count (in CA3 region) were studied using H&E and cresyl violet stained sections. Dendritic arborization pattern of CA3 pyramidal neuron was investigated by concentric circle method. Progressive learning abilities were found to be decreased in RF-EMR exposed rats. Memory retention test performed 24 h after the last training revealed minor spatial memory deficit in RF-EMR exposed group. However, RF-EMR exposed rats exhibited poor spatial memory retention when tested 48 h after the final trial. Hirano bodies and Granulovacuolar bodies were absent in the CA3 pyramidal neurons of different groups studied. Nevertheless, RF-EMR exposure affected the viable cell count in dorsal hippocampal CA3 region. RF-EMR exposure influenced dendritic arborization pattern of both apical and basal dendritic trees in RF-EMR exposed rats. Structural changes found in the hippocampus of RF-EMR exposed rats could be one of the possible reasons for altered cognition.

    Cerebral ischemia is one of the leading causes of death and long-term disability in aging populations, due to the frequent occurrence of irreversible brain damage and subsequent loss of neuronal function which lead to cognitive impairment and some motor dysfunction. In the present study, the real time course of motor and cognitive functions were evaluated following the chronic cerebral ischemia induced by permanent, bilateral occlusion of the common carotid arteries (PBOCCA). Male Sprague Dawley rats (200-300g) were subjected to PBOCCA or sham-operated surgery and tested 1, 2, 3 and 4 weeks following the ischemic insult. The results showed that PBOCCA significantly reduced step-through latency in a passive avoidance task at all time points when compared to the sham-operated group. PBOCCA rats also showed significant increase in escape latencies during training in the Morris water maze, as well as a reduction of the percentage of times spend in target quadrant of the maze at all time points following the occlusion. Importantly, there were no significant changes in locomotor activity between PBOCCA and sham-operated groups. The BDNF expression in the hippocampus was 29.3±3.1% and 40.1±2.6% on day 14 and 28 post PBOCCA, respectively compared to sham-operated group. Present data suggest that the PBOCCA procedure effectively induces behavioral, cognitive symptoms associated with cerebral ischemia and, consequently, provides a valuable model to study ischemia and related neurodegenerative disorder such as Alzheimer's disease and vascular dementia.

    Full Text Available Background: Functional magnetic resonance imaging (fMRI, a non-invasive technique with high spatial resolution and blood oxygen level dependent (BOLD contrast, has been applied to localize and map cognitive functions in the clinical condition of chronic intractable epilepsy. Purpose: fMRI was used to map the language and memory network in patients of chronic intractable epilepsy pre- and post-surgery. Materials and Methods: After obtaining approval from the institutional ethics committee, six patients with intractable epilepsy with an equal number of age-matched controls were recruited in the study. A 1.5 T MR scanner with 12-channel head coil, integrated with audio-visual fMRI accessories was used. Echo planar imaging sequence was used for BOLD studies. There were two sessions in TLE (pre- and post-surgery. Results: In TLE patients, BOLD activation increased post-surgery in comparison of pre-surgery in inferior frontal gyrus (IFG, middle frontal gyrus (MFG, and superior temporal gyrus (STG, during semantic lexical, judgment, comprehension, and semantic memory tasks. Conclusion: Functional MRI is useful to study the basic concepts related to language and memory lateralization in TLE and guide surgeons for preservation of important brain areas during ATLR. This will help in understanding future directions for the diagnosis and treatment of such disease.

    Full Text Available The diagnosis of Attention Deficit Hyperactivity Disorder (ADHD often results in chronic treatment with psychostimulants such as methylphenidate (MPH, Ritalin®. With increases in misdiagnosis of ADHD, children may be inappropriately exposed to chronic psychostimulant treatment during development. The aim of this study was to assess the effect of chronic Ritalin treatment on cognitive and neural development in misdiagnosed “normal” (Wistar Kyoto, WKY rats and in Spontaneously Hypertensive Rats (SHR, a model of ADHD. Adolescent male animals were treated for four weeks with oral Ritalin® (2 × 2 mg/kg/day or distilled water (dH2O. The effect of chronic treatment on delayed reinforcement tasks (DRT and tyrosine hydroxylase immunoreactivity (TH-ir in the prefrontal cortex was assessed. Two weeks following chronic treatment, WKY rats previously exposed to MPH chose the delayed reinforcer significantly less than the dH2O treated controls in both the DRT and extinction task. MPH treatment did not significantly alter cognitive performance in the SHR. TH-ir in the infralimbic cortex was significantly altered by age and behavioural experience in WKY and SHR, however this effect was not evident in WKY rats treated with MPH. These results suggest that chronic treatment with MPH throughout adolescence in “normal” WKY rats increased impulsive choice and altered catecholamine development when compared to vehicle controls.

    Chronic lung disease (CLD) in children represents a heterogeneous group of many clinico-pathological entities with risk of adverse impact of chronic or intermittent hypoxia. So far, few researchers have investigated the cognitive function in these children, and the role of auditory P300 in the assessment of their cognitive function has not been investigated yet. This study was designed to assess the cognitive functions among schoolchildren with different chronic pulmonary diseases using both auditory P300 and Stanford-Binet test. This cross-sectional study included 40 school-aged children who were suffering from chronic chest troubles other than asthma and 30 healthy children of similar age, gender and socioeconomic state as a control group. All subjects were evaluated through clinical examination, radiological evaluation and spirometry. Audiological evaluation included (basic otological examination, pure-tone, speech audiometry and immittancemetry). Cognitive function was assessed by auditory P300 and psychological evaluation using Stanford-Binet test (4th edition). Children with chronic lung diseases had significantly lower anthropometric measures compared to healthy controls. They had statistically significant lower IQ scores and delayed P300 latencies denoting lower cognitive abilities. Cognitive dysfunction correlated to severity of disease. P300 latencies were prolonged among hypoxic patients. Cognitive deficits in children with different chronic lung diseases were best detected using both Stanford-Binet test and auditory P300. P300 is an easy objective tool. P300 is affected early with hypoxia and could alarm subtle cognitive dysfunction. PMID:27075686

    Bilobalide (BB), a unique constituent of Ginkgo biloba, has powerful neuroprotection and stress-alleviating properties. However, whether BB exerts a positive effect on depression and cognitive deficit induced by chronic stress is not known. The present study was designed to investigate the influence of BB on depression and cognitive impairments induced by chronic unpredictable mild stress (CUMS) in mice. During daily exposure to stressors for 5 consecutive weeks, mice were administered BB at the doses of 0, 3, or 6 mg/kg/day intraperitoneally. We replicated the finding that CUMS induced depression-like behavior and cognitive deficits as the CUMS+vehicle (VEH) group showed a significant increase in immobility in the tail suspension test, a decrease in the discrimination index of the novel object recognition task, and increased latency to platform and decreased number of platform crossings in the Morris water maze compared with the control+VEH group. Chronic administration of BB effectively reversed these alterations. In addition, the CUMS+VEH group showed significantly higher levels of baseline serum corticosterone than those of the control+VEH group and BB dose-dependently inhibited this effect. Our results suggest that BB may be useful for inhibition of depression-like behavior and cognitive deficits, and this protective effect was possibly exerted partly through an action on the hypothalamic-pituitary-adrenal axis.

    Full Text Available Previous reports documented abnormalities in cognitive functions and decision-making (DM in patients with chronic pain, but these changes are not consistent across studies. Reasons for these discordant findings might include the presence of confounders, variability in chronic pain conditions, and the use of different cognitive tests. The present study was aimed to add evidence in this field, by exploring the cognitive profile of a specific type of chronic pain, i.e.: chronic low back pain (cLBP.Twenty four cLBP patients and 24 healthy controls underwent a neuropsychological battery and we focused on emotional DM abilities by means of Iowa gambling task (IGT. During IGT, behavioral responses and the electroencephalogram (EEG were recorded in 12 patients and 12 controls. Event-related potentials (ERPs were averaged offline from EEG epochs locked to the feedback presentation (4000 ms duration, from 2000 ms before to 2000 ms after the feedback onset separately for wins and losses and the feedback-related negativity (FRN and P300 peak-to-peak amplitudes were calculated. Among cognitive measures, cLBP patients scored lower than controls in the modified card sorting test (MCST and the score in this test was significantly influenced by pain duration and intensity. Behavioural IGT results documented worse performance and the absence of a learning process during the test in cLBP patients compared to controls, with no effect of pain characteristics. ERPs findings documented abnormal feedback processing in patients during IGT.cLBP patients showed poor performance in the MCST and the IGT. Abnormal feedback processing may be secondary to impingement of chronic pain in brain areas involved in DM or suggest the presence of a predisposing factor related to pain chronification. These abnormalities might contribute to the impairment in the work and family settings that often cLBP patients report.

    Chronic restraint stress (CRS) causes hippocampal neurodegeneration and hippocampus-dependent cognitive deficits. Flupirtine represents neuroprotective effects and we have previously shown that flupirtine can protect against memory impairment induced by acute stress. The present study aimed to investigate whether flupirtine could alleviate spatial learning and memory impairment and hippocampal apoptosis induced by CRS. CRS mice were restrained in well-ventilated Plexiglass tubes for 6h daily beginning from 10:00 to 16:00 for 21 consecutive days. Mice were injected with flupirtine (10mg/kg and 25mg/kg) or vehicle (10% DMSO) 30min before restraint stress for 21 days. After stressor cessation, the spatial learning and memory, dendritic spine density, injured neurons and the levels of Bcl-2, Bax, p-Akt, p-GSK-3β, p-Erk1/2 and synaptophysin of hippocampal tissues were examined. Our results showed that flupirtine significantly prevented spatial learning and memory impairment induced by CRS in the Morris water maze. In addition, flupirtine (10mg/kg and 25mg/kg) treatment alleviated neuronal apoptosis and the reduction of dendritic spine density and synaptophysin expression in the hippocampal CA1 region of CRS mice. Furthermore, flupirtine (10mg/kg and 25mg/kg) treatment significantly decreased the expression of Bax and increased the p-Akt and p-GSK-3β, and flupirtine (25mg/kg) treatment up-regulated the p-Erk1/2 in the hippocampus of CRS mice. These results suggested that flupirtine exerted protective effects on the CRS-induced cognitive impairment and hippocampal neuronal apoptosis, which is possibly associated with the activation of Akt/GSK-3β and Erk1/2 signaling pathways.

    Two chronic, traumatic brain injury (TBI) cases are presented, where cognitive function improved following treatment with transcranial light emitting diodes (LEDs). At age 59, P1 had closed-head injury from a motor vehicle accident (MVA) without loss of consciousness and normal MRI, but unable to return to work as development specialist in internet marketing, due to cognitive dysfunction. At 7 years post-MVA, she began transcranial LED treatments with cluster heads (2.1" diameter with 61 diodes each - 9x633nm, 52x870nm; 12-15mW per diode; total power, 500mW; 22.2 mW/cm2) on bilateral frontal, temporal, parietal, occipital and midline sagittal areas (13.3 J/cm2 at scalp, estimated 0.4 J/cm2 to brain cortex per area). Prior to transcranial LED, focused time on computer was 20 minutes. After 2 months of weekly, transcranial LED treatments, increased to 3 hours on computer. Performs nightly home treatments (now, 5 years, age 72); if stops treating >2 weeks, regresses. P2 (age 52F) had history of closed-head injuries related to sports/military training and recent fall. MRI shows fronto-parietal cortical atrophy. Pre-LED, was not able to work for 6 months and scored below average on attention, memory and executive function. Performed nightly transcranial LED treatments at home (9 months) with similar LED device, on frontal and parietal areas. After 4 months of LED treatments, returned to work as executive consultant, international technology consulting firm. Neuropsychological testing (post- 9 months of transcranial LED) showed significant improvement in memory and executive functioning (range, +1 to +2 SD improvement). Case 2 reported reduction in PTSD symptoms.

    Moderator analyses are reported for posttreatment outcomes in a large, randomized, controlled effectiveness trial for chronic pain for hip and knee osteoarthritis (N = 256). Pain Coping Skills Training, a form of cognitive behavioral therapy, was compared to usual care. Treatment was delivered by nurse practitioners in patients' community doctors' offices. Consistent with meta-analyses of pain cognitive behavioral therapy efficacy, treatment effects in this trial were significant for several primary and secondary outcomes, but tended to be small. This study was designed to examine differential response to treatment for patient subgroups to guide clinical decision-making for treatment. Based on existing literature, demographic (age, sex, race/ethnicity, and education) and clinical variables (disease severity, body mass index, patient treatment expectations, depression, and patient pain coping style) were specified a priori as potential moderators. Trial outcome variables (N = 15) included pain, fatigue, self-efficacy, quality of life, catastrophizing, and use of pain medication. Results yielded 5 significant moderators for outcomes at posttreatment: pain coping style, patient expectation for treatment response, radiographically assessed disease severity, age, and education. Thus, sex, race/ethnicity, body mass index, and depression at baseline were not associated with level of treatment response. In contrast, patients with interpersonal problems associated with pain coping did not benefit much from the treatment. Although most patients projected positive expectations for the treatment prior to randomization, only those with moderate to high expectations benefited. Patients with moderate to high osteoarthritis disease severity showed stronger treatment effects. Finally, the oldest and most educated patients showed strong treatment effects, while younger and less educated did not. PMID:27227692

    James J. Pestka

    2010-06-01

    Full Text Available The trichothecene mycotoxin deoxynivalenol (DON is commonly encountered in human cereal foods throughout the world as a result of infestation of grains in the field and in storage by the fungus Fusarium. Significant questions remain regarding the risks posed to humans from acute and chronic DON ingestion, and how to manage these risks without imperiling access to nutritionally important food commodities. Modulation of the innate immune system appears particularly critical to DON’s toxic effects. Specifically, DON induces activation of mitogen-activated protein kinases (MAPKs in macrophages and monocytes, which mediate robust induction of proinflammatory gene expression—effects that can be recapitulated in intact animals. The initiating mechanisms for DON-induced ribotoxic stress response appear to involve the (1 activation of constitutive protein kinases on the damaged ribosome and (2 autophagy of the chaperone GRP78 with consequent activation of the ER stress response. Pathological sequelae resulting from chronic low dose exposure include anorexia, impaired weight gain, growth hormone dysregulation and aberrant IgA production whereas acute high dose exposure evokes gastroenteritis, emesis and a shock-like syndrome. Taken together, the capacity of DON to evoke ribotoxic stress in mononuclear phagocytes contributes significantly to its acute and chronic toxic effects in vivo. It is anticipated that these investigations will enable the identification of robust biomarkers of effect that will be applicable to epidemiological studies of the human health effects of this common mycotoxin.

    Resveratrol is a polyphenol exhibiting antioxidant and neuroprotective effects in neurodegenerative diseases. However, neuroprotective properties during normal aging have not been clearly demonstrated. We analyzed the in vivo effects of chronic administration of resveratrol (20 mg/kg/day for 4 weeks) in old male rats (Wistar, 20 months), on tryptophan hydroxylase (TPH) and tyrosine hydroxylase (TH) activities which mediate central monoaminergic neurotransmitters synthesis, and besides, on hippocampal-dependent working memory test (radial maze). Our results show an age-related decline in neurochemical parameters that were reversed by resveratrol administration. The resveratrol treatment enhances serotonin (5-HT) levels in pineal gland, in hippocampus, and in striatum, and those of noradrenaline (NA) in hippocampus and also dopamine (DA) in striatum. These changes were largely due to an increased activity of TPH-1 (463 % in pineal gland), TPH-2 (70-51 % in hippocampus and striatum), and TH (150-36 % in hippocampus and striatum). Additionally, the observed hippocampal effects correlate with a resveratrol-induced restorative effect on working memory (radial maze). In conclusion, this study suggests resveratrol treatment as a restoring therapy for the impaired cognitive functions occurring along normal aging process, by preventing 5-HT, DA, and NA neurotransmission decline.

    Full Text Available Abstract Background Chronic neuroinflammation is a hallmark of several neurological disorders associated with cognitive loss. Activated microglia and secreted factors such as tumor necrosis factor (TNF-α are key mediators of neuroinflammation and may contribute to neuronal dysfunction. Our study was aimed to evaluate the therapeutic potential of a novel analog of thalidomide, 3,6'-dithiothalidomide (DT, an agent with anti-TNF-α activity, in a model of chronic neuroinflammation. Methods Lipopolysaccharide or artificial cerebrospinal fluid was infused into the fourth ventricle of three-month-old rats for 28 days. Starting on day 29, animals received daily intraperitoneal injections of DT (56 mg/kg/day or vehicle for 14 days. Thereafter, cognitive function was assessed by novel object recognition, novel place recognition and Morris water maze, and animals were euthanized 25 min following water maze probe test evaluation. Results Chronic LPS-infusion was characterized by increased gene expression of the proinflammatory cytokines TNF-α and IL-1β in the hippocampus. Treatment with DT normalized TNF-α levels back to control levels but not IL-1β. Treatment with DT attenuated the expression of TLR2, TLR4, IRAK1 and Hmgb1, all genes involved in the TLR-mediated signaling pathway associated with classical microglia activation. However DT did not impact the numbers of MHC Class II immunoreactive cells. Chronic neuroinflammation impaired novel place recognition, spatial learning and memory function; but it did not impact novel object recognition. Importantly, treatment with DT restored cognitive function in LPS-infused animals and normalized the fraction of hippocampal neurons expressing the plasticity-related immediate-early gene Arc. Conclusion Our data demonstrate that the TNF-α synthesis inhibitor DT can significantly reverse hippocampus-dependent cognitive deficits induced by chronic neuroinflammation. These results suggest that TNF-α is a

    Full Text Available Animals that experience adverse events in early life often have life-long changes to their physiology and behavior. Long-term effects of stress during early life have been studied extensively, but less attention has been given to the consequences of negative experiences solely during the adolescent phase. Adolescence is a particularly sensitive period of life when regulation of the glucocorticoid stress hormone response matures and specific regions in the brain undergo considerable change. Aversive experiences during this time might, therefore, be expected to generate long-term consequences for the adult phenotype. Here we investigated the long-term effects of exposure to chronic unpredictable stress during adolescence on adult decision making, coping response, cognitive bias, and exploratory behavior in rats. Rats exposed to chronic unpredictable stress (e.g. isolation, crowding, cage tilt were compared to control animals that were maintained in standard, predictable conditions throughout development. Unpredictable stress during adolescence resulted in a suite of long-term behavioral and cognitive changes including a negative cognitive bias (F1,12 = 5.000, P < 0.05, altered coping response (T1,14 = 2.216, P = 0.04, and accelerated decision making (T1,14 = 3.245, P = 0.01. Exposure to chronic stress during adolescence also caused a short-term increase in boldness behaviors; in a novel object test 15 days after the last stressor, animals exposed to chronic unpredictable stress had decreased latencies to leave a familiar shelter and approach a novel object (T1,14 = 2.240, P = 0.04; T1,14 = 2.419, P = 0.03, respectively. The results showed that stress during adolescence has long-term impacts on behavior and cognition that affect the interpretation of ambiguous stimuli, behavioral response to adverse events, and how animals make decisions. Stress during adolescence also induced short-term changes in the way animals moved around a novel environment.

    BACKGROUND: Cognitive behaviour therapy (CBT) is known to reduce fatigue severity in chronic fatigue syndrome (CFS). How this change in symptomatology is accomplished is not yet understood. The purpose of the present study was to determine whether the effect of CBT on fatigue is mediated by an increase in physical activity. METHOD: Three randomized controlled trials were reanalysed, previously conducted to evaluate the efficacy of CBT for CFS. In all samples, actigraphy was used to assess the...

    Individuals with chronic fatigue syndrome (CFS) have heightened sensitivity and increased symptoms following various physiologic challenges, such as orthostatic stress, physical exercise, and cognitive challenges. Similar heightened sensitivity to the same stressors in fibromyalgia (FM) has led investigators to propose that these findings reflect a state of central sensitivity. A large body of evidence supports the concept of central sensitivity in FM. A more modest literature provides partia...

    Chronic pain is a major health problem in developed countries where it may affect as much as 20% of the adult population. There have been no significant clinical breakthroughs in therapeutic options for persons with chronic neuropathic pain. These limitations underscore the importance of developing new therapies for this disabling pain syndrome. We have reviewed the limitations of the present treatment strategies for chronic pain, neurophysiology of somatosensory transmission and nociception, mechanisms of neuropathic pain, the concept of a "pain matrix" and the "top-down" modulation of pain, and the cognitive affective role in processing of the pain experience. We found that affective and cognitive aspects of pain constitute important considerations in achieving improvements in the outcomes of pain neuromodulation in patients with chronic neuropathic pain. Based on our review, we propose that future novel neuromodulatory therapeutic strategies should be directed at areas in the brain that are involved in the neural mechanisms of reward valuation and appetitive motivation such as nucleus accumbens, ventral tegmental area, and prefrontal cortex.

    Increasing numbers of studies have suggested that the gut microbiota is involved in the pathophysiology of stress-related disorders. Chronic stress can cause behavioral, cognitive, biochemical, and gut microbiota aberrations. Gut bacteria can communicate with the host through the microbiota-gut-brain axis (which mainly includes the immune, neuroendocrine, and neural pathways) to influence brain and behavior. It is hypothesized that administration of probiotics can improve chronic-stress-induced depression. In order to examine this hypothesis, the chronic restraint stress depression model was established in this study. Adult specific pathogen free (SPF) Sprague-Dawley rats were subjected to 21 days of restraint stress followed by behavioral testing (including the sucrose preference test (SPT), elevated-plus maze test, open-field test (OFT), object recognition test (ORT), and object placement test (OPT)) and biochemical analysis. Supplemental Lactobacillus helveticus NS8 was provided every day during stress until the end of experiment, and selective serotonin reuptake inhibitor (SSRI) citalopram (CIT) served as a positive control. Results showed that L. helveticus NS8 improved chronic restraint stress-induced behavioral (anxiety and depression) and cognitive dysfunction, showing an effect similar to and better than that of CIT. L. helveticus NS8 also resulted in lower plasma corticosterone (CORT) and adrenocorticotropic hormone (ACTH) levels, higher plasma interleukin-10 (IL-10) levels, restored hippocampal serotonin (5-HT) and norepinephrine (NE) levels, and more hippocampal brain-derived neurotrophic factor (BDNF) mRNA expression than in chronic stress rats. Taken together, these results indicate an anti-depressant effect of L. helveticus NS8 in rats subjected to chronic restraint stress depression and that this effect could be due to the microbiota-gut-brain axis. They also suggest the therapeutic potential of L. helveticus NS8 in stress-related and possibly other

    Full Text Available Chronic pain is a complex physiological and psychological phenomenon. Implicit learning mechanisms contribute to the development of chronic pain and to persistent changes in the central nervous system. We hypothesized that these central abnormalities can be remedied with Cognitive Behavioral Therapy (CBT. Specifically, since regions of the anterior Default Mode Network (DMN are centrally involved in emotional regulation via connections with limbic regions, such as the amygdala, remediation of maladaptive behavioral and cognitive patterns as a result of CBT for chronic pain would manifest itself as a change in the intrinsic functional connectivity (iFC between these prefrontal and limbic regions. Resting-state functional neuroimaging was performed in patients with chronic pain before and after 11-week CBT (n = 19, as well as a matched (ages 19–59, both sexes active control group of patients who received educational materials (n = 19. Participants were randomized prior to the intervention. To investigate the differential impact of treatment on intrinsic functional connectivity (iFC, we compared pre–post differences in iFC between groups. In addition, we performed exploratory whole brain analyses of changes in fractional amplitude of low frequency fluctuations (fALFF. The course of CBT led to significant improvements in clinical measures of pain and self-efficacy for coping with chronic pain. Significant group differences in pre–post changes in both iFC and fALFF were correlated with clinical outcomes. Compared to control patients, iFC between the anterior DMN and the amygdala/periaqueductal gray decreased following CBT, whereas iFC between the basal ganglia network and the right secondary somatosensory cortex increased following CBT. CBT patients also had increased post-therapy fALFF in the bilateral posterior cingulate and the cerebellum. By delineating neuroplasticity associated with CBT-related improvements, these results add to

    Objectives and Methods: A systematic review and meta-analysis were performed to estimate the size and variability of the association between chronic pain (CP) and poorer cognitive test performances as a function of individual tests, pain sub-types, and study sources on 22 studies having (1) a control group, (2) reported means and standard deviations (SDs) and (3) tests studied at least 3 times. Results: CP patients performed significantly poorer with small to moderate effects (d = −.31 to −.57) on Digit Span Backward; STROOP Word; Color and Color-Word; Digit Symbol; Trail Making A and B; Rey Auditory Learning Immediate and Delayed Recall and Recognition. For these 10 measures, single effects (no interaction) were supported (I2 = 0%–8%) and Random and Fixed models yielded similar results. No group differences were found for Corsi Blocks Forward or Wisconsin Cart Sorting Test Categories Achieved, or Perseveration. Effects for the Rey Complex Figure Immediate and Delayed Recall were significant, but effect size was inconclusive, given moderate to high heterogeneity and lack of consistency between Random and Fixed models. For the Paced Auditory Serial Addition Test, there was a homogeneous (I2 = 0%) and significantly lower performance in fibromyalgia (d = −.47), but no effect in diagnostically undifferentiated pain samples, and wide variability across studies of whiplash (d = −.15 to −1.04, I2 = 60%). Conclusion: The magnitude and consistency of the CP – cognition effect depended on the test, pain subgroup and study source. Summary points Among tests showing a chronic pain (CP) – cognition effect, the magnitude of this association was consistently small to moderate across tests. Effect size estimation was inconclusive for Digit Span Forwards, the Paced Auditory Serial Addition Test and the Rey Complex Figure Test. Variance was too heterogeneous for testing cognitive domain specificity of the CP – cognition effect. PMID:27583141

The aim of the present study was to evaluate the effects of adjunctive treatment with donepezil on cognition in patients with chronic schizophrenia. This was a 12-week, double-blind, randomized, placebo-controlled study of donepezil as an adjunct to antipsychotic drug therapy in patients with chronic stable schizophrenia. Sixty-one subjects were randomized to receive donepezil 5 mg/day (n=31 and/or placebo (n=30. A nine-test neuropsychological assessment battery was administered at baseline and at the end of the study. At the 12-week end point, the donepezil group showed significant improvements in the Wechsler Memory Scale Third Edition Spatial Span, Brief Visuospatial Memory Test total recall and delayed recall, Trail-Making Test Part A, and Category Fluency Test-animal naming (all P≤0.018. Compared with placebo, donepezil was associated with significant improvement in several cognitive domains, including working memory, speed of information processing, and visual learning and memory (P≤0.008. The results of the present study suggest that adjunctive use of donepezil is beneficial for improving cognitive function in patients with schizophrenia.

    It has been recognized that during chronic inflammatory systemic diseases (CIDs) maladaptations of the immune, nervous, endocrine and reproductive system occur. Maladaptation leads to disease sequelae in CIDs. The ultimate reason of disease sequelae in CIDs remained unclear because clinicians do not consider bodily energy trade-offs and evolutionary medicine. We review the evolution of physiological supersystems, fitness consequences of genes involved in CIDs during different life-history sta...

    Full Text Available Background/Aims: In recent years, the relationship between chronic kidney disease (CKD and cognitive impairment has been attracting attention. Cerebral small vessel disease (SVD is also associated with an increased risk of cognitive impairment. However, it is still unknown whether CKD markers are associated with cognitive impairment independently of SVD in elderly diabetic patients. Methods: Seventy-nine type 2 diabetic patients (mean age, 76.0 years were enrolled in the present study. CKD was defined as the presence of albuminuria and/or a low estimated glomerular filtration rate (eGFR 2. SVD was evaluated by the presence and severity of silent brain infarcts (SBIs and white matter lesions (WMLs on brain magnetic resonance imaging. Neuropsychological tests were assessed using four validated cognitive instruments. Results: In multiple linear regression analyses, albuminuria was associated with worse modified Stroop Color Word scores (β = 0.284, p = 0.017 and low eGFR was associated with reduced Digit Symbol Substitution scores (β = -0.224, p = 0.026 after adjustment for age, sex, education years, diabetes duration, hypertension, multiple SBIs, and advanced WMLs. In contrast, there were no significant associations between CKD markers and Mini-Mental State Examination or Word Recall scores. Conclusion: Our findings suggest that albuminuria and low eGFR are associated with frontal lobe dysfunction independently of SVD in elderly type 2 diabetic patients.

    Exercise rehabilitation is recommended increasingly for patients with chronic obstructive pulmonary disease (COPD). This study examined the effect of exercise and education on 79 older adults (M age = 66.6 +/- 6.5 years; 53% female) with COPD, randomly assigned to 10 weeks of (a) exercise, education, and stress management (EXESM; n = 29); (b) education and stress management (ESM; n = 25); or (c) waiting list (WL; n = 25). EXESM included 37 sessions of exercise, 16 educational lectures, and 10 weekly stress management classes. ESM included only the 16 lectures and 10 stress management classes. Before and after the intervention, assessments were conducted of physiological functioning (pulmonary function, exercise endurance), psychological well-being (depression, anxiety, quality of life), and cognitive functioning (attention, motor speed, mental efficiency, verbal processing). Repeated measures multivariate analysis of variance indicated that EXESM participants experienced changes not observed among ESM and WL participants, including improved endurance, reduced anxiety, and improved cognitive performance (verbal fluency).

    Full Text Available In a pilot group of six patients suffering from chronic temporal lobe epilepsy, single photon emission computerized tomography (SPECT has been used to image the changes in relative cerebral blood flow between rest (static scan and conditions of cognitive activation (activated scan. The cognitive challenge used during activation comprised a test of word memory, and the performance was expressed as a word memory score (WMS for each individual. An activation index (AI was calculated from the mean normalized density counts in specific regions of interest (ROIs, and values obtained were analysed for correlation with the WMS. The mean AI was increased significantly in the right lateral temporal cortex, the right and left inferior frontal regions, the left temporal pole, and the right medial temporal cortex. A positive correlation with the WMS was found in the medial temporal cortices, and this relationship was significant for the right medial temporal ROI.

    Previous reports on survivors of Reye's syndrome have indicated a high proportion of significant neurological and intellectual sequelae. However, increasingly sophisticated monitoring and therapeutic techniques have diminished both the mortality and morbidity of this disease. Our present study documented the relatively good intellectual and neurological prognosis for recent survivors of Reye's at our institution and explored the emotional impact of this illness on survivor's families. The significant emotional problems of the children and their families were in striking contrast to the relatively good intellectual and academic recovery. Nine of the 16 survivors showed emotional disruption (primarily somatic complaints, anxiety, and depression). Fourteen of 16 mothers interviewed continued to suffer from anxiety, depression, and overprotective behavior as long as 5 years after their child's illness. In many respects, the parents endured more prolonged and profound suffering than did the children. These findings have implications for the delivery of follow-up care to families of survivors.

    Opioids constitute the basis for pharmacological treatment of moderate to severe pain in cancer pain and non-cancer pain patients. Their action is mediated by the activation of opioid receptors, which integrates the pain modulation system with other effects in the central nervous system including cognition resulting in complex interactions between pain, opioids and cognition. The literature on this complexity is sparse and information regarding the cognitive effects of opioids in chronic pain patients is substantially lacking. Two previous systematic reviews on cancer pain and non-cancer pain patients only using controlled studies were updated. Fourteen controlled studies on the cognitive effects of opioids in chronic non-cancer pain patients and eleven controlled studies in cancer pain patients were included and analyzed. Opioid treatment involved slightly opposite outcomes in the two patient groups: no effects or worsening of cognitive function in cancer pain patients and no effect or improvements in the chronic non-cancer pain patients, however, due to methodological limitations and a huge variety of designs definite conclusions are difficult to draw from the studies. In studies of higher quality of evidence opioid induced deficits in cognitive functioning were associated with dose increase and the use of supplemental doses of opioids in cancer patients. Future perspectives should comprise the conduction of high quality randomized controlled trials (RCTs) involving relevant control groups and validated neuropsychological assessments tools before and after opioid treatment in order to further explore the complex interaction between pain, opioids and cognition.

    Performing a cognitive task while balancing can result in either increased or decreased sway depending on the nature of the cognitive task, and is commonly used in pathologic populations to evaluate postural performance. A total of 39 participants were recruited into two groups: uninjured controls (n=20, age: 21.9±2.1 years, height: 175.0±11.2cm, mass: 71.3±14.9kg) and chronic ankle instability (n=19, age: 22.1±5.6 years, height: 169.7±7.7cm, mass: 72.9±17.3kg). Participants were asked to perform one of three cognitive tasks while maintaining single limb balance. Cognitive tasks included backwards counting by 3 (BC), the manikin test (MAN), and random number generation (RNG). Time-to-boundary minima, mean, and standard deviations were calculated and compared between groups as pre to post change scores. Effect sizes and 95% confidence intervals were also calculated to test for group differences and the effect of task performance on sway. No significant main effects of Group or Group by Task interactions were identified (p>0.05). However, a significant multivariate main effect of Task was identified in BC (p=0.001, F(6, 32)=4.804) and RNG (ppostural-suprapostural interactions across multiple cognitive task domains. Both the BC and RNG tasks resulted in less sway for all participants. Our results suggest that dual-task interference in the CAI population may not be present as previous research would suggest.

    The irritable bowel syndrome (IBS) is a common chronic functional gastrointestinal disorder world wide that lasts for decades. The human gut harbors a diverse population of microbial organisms which is symbiotic and important for well being. However, studies on conventional, germ-free, and obese animals have shown that alteration in normal commensal gut microbiota and an increase in pathogenic microbiota-termed "dysbiosis", impact gut function, homeostasis, and health. Diarrhea, constipation, visceral hypersensitivity, and abdominal pain arise in IBS from the gut-induced dysfunctional metabolic, immune, and neuro-immune communication. Dysbiosis in IBS is associated with gut inflammation. Gut-related inflammation is pivotal in promoting endotoxemia, systemic inflammation, and neuroinflammation. A significant proportion of IBS patients chronically consume alcohol, non-steroidal anti-inflammatories, and fatty diet; they may also suffer from co-morbid respiratory, neuromuscular, psychological, sleep, and neurological disorders. The above pathophysiological substrate is underpinned by dysbiosis, and dysfunctional bidirectional "Gut-Brain Axis" pathways. Pathogenic gut microbiota-related systemic inflammation (due to increased lipopolysaccharide and pro-inflammatory cytokines, and barrier dysfunction), may trigger neuroinflammation enhancing dysfunctional brain regions including hippocampus and cerebellum. These as well as dysfunctional vago-vagal gut-brain axis may promote cognitive impairment. Indeed, inflammation is characteristic of a broad spectrum of neurodegenerative diseases that manifest demntia. It is argued that an awareness of pathophysiological impact of IBS and implementation of appropriate therapeutic measures may prevent cognitive impairment and minimize vulnerability to dementia.

    Self-management programs based on social cognitive theory are useful to improve health care outcomes for patients with chronic diseases in Western culture. The purpose of this review is to identify and synthesize published research on the theory to enhance self-efficacy in disease management and examine its applicability to Korean culture regarding the learning strategies used. Ultimately, it was to identify the optimal use of these learning strategies to improve the self-efficacy of Korean patients in self-management of their hypertension and diabetic mellitus. The authors searched the Korean and international research databases from January 2000 to September 2009. Twenty studies were selected and reviewed. The most frequently used learning strategies of social cognitive theory was skill mastery by practice and feedback (N = 13), followed by social or verbal persuasion by group members (N = 7) and, however, observation learning and reinterpretation of symptoms by debriefing or discussion were not used any of the studies. Eight studies used only one strategy to enhance self-efficacy and six used two. A lack of consistency regarding the content and clinical efficacy of the self-efficacy theory-based self-management programs is found among the reviewed studies on enhancing self-efficacy in Koreans with hypertension and diabetes mellitus. Further research on the effectiveness of these theory-based self-management programs for patients with chronic diseases in Korea and other countries is recommended.

    Objective To estimate the prevalence of cognitive impairment (CI) among patients recently diagnosed with type 2 diabetes (RDD) and to identify any relationships between CI and RDD comorbidities. Methods: One thousand seven hundred twelve patients with RDD participated in a cross-sectional study. The patients’ sociodemographic and clinical data were registered. Results The sample population had an average age of 51 ± 11 years, and 63.26% of the patients were female. CI was diagnosed in 38 patients (2.2%) and was more common among both females (2.8% vs. 1.3%, p = 0.063) and the elderly (0% at an age ≤ 30 years vs. 10.4% at an age > 70 years, p = 0.0001). Rheumatoid arthritis (present in 15.8% vs. absent in 2.1%) and asthma (13% vs. 2.1%) correlated significantly with CI based on the results of our logistic regression analysis. Conclusion Age, female gender, rheumatoid arthritis and asthma are risk factors for CI in the setting of RDD. PMID:26517541

Methods A hypoxia-reoxygen device was used to prepare the model of CIH. Meanwhile, the PD mouse model was built by intraperitoneal injection of paraquat (PQ. The cognitive function was evaluated by Y-type electric maze and step-down test. Syn expression in the hippocampus was estimated by immunohistochemistry. The neuron structure in the hippocampus was observed by HE staining, Nissl staining and the electron microscope. Results Comparing to control group, a significant decrease was found in learning and memorizing performance (P < 0.05, for all and the amount of neuron, while a significant increase was seen in total reaction time (TRT and error reaction (ER in Y-type electric maze and step-down test and the gray value of Syn in the hippocampus in PQ, CIH, and PQ + CIH groups. Various degrees of anomaly were observed in neuron structure of hippocampus by HE staining, Nissl staining and electron microscopy in PQ, CIH, and PQ + CIH groups, while presented most obviously in thelatter group. Conclusion The PQ-induced impairment of cognitive function in PD model mice was aggravated by CIH, which may be related to the damage of neuron structure and the decrease of synaptic function in hippocampus.

    Repeated mild traumatic brain injury (mTBI) can cause sustained cognitive and psychiatric changes, as well as neurodegeneration, but the underlying mechanisms remain unclear. We examined histologic, neurophysiological, and cognitive changes after single or repeated (three injuries) mTBI using the rat lateral fluid percussion (LFP) model. Repeated mTBI caused substantial neuronal cell loss and significantly increased numbers of activated microglia in both ipsilateral and contralateral hippocampus on post-injury day (PID) 28. Long-term potentiation (LTP) could not be induced on PID 28 after repeated mTBI in ex vivo hippocampal slices from either hemisphere. N-Methyl-D-aspartate (NMDA) receptor-mediated responses were significantly attenuated after repeated mTBI, with no significant changes in α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor-mediated responses. Long-term potentiation was elicited in slices after single mTBI, with potentiation significantly increased in ipsilateral versus contralateral hippocampus. After repeated mTBI, rats displayed cognitive impairments in the Morris water maze (MWM) and novel object recognition (NOR) tests. Thus, repeated mTBI causes deficits in the hippocampal function and changes in excitatory synaptic neurotransmission, which are associated with chronic neuroinflammation and neurodegeneration.

    Limiting enzymes in the synthesis of brain monoamines seems to be susceptible to oxidative damage, one of the most important factors in aging. It has been suggested that the use of anti-oxidants can reduce the rate of free radical production related with aging and the associated damage. Therefore, this study aims to analyze the effects of the chronic treatments with the anti-oxidant α-tocopherol (vitamin E) on central monoamines (high-performance liquid chromatography [HPLC] analysis) mediating cognitive functions, as well as on the evaluation of memory and motor abilities in old rats measured by radial maze, Barnes maze, novel object recognition test, and rotarod test. Results show that α-tocopherol significantly increased in a dose- and/or time-dependent manner the synthesis rate and the levels of monoaminergic neurotransmitters (serotonin, dopamine, and noradrenaline) in the hippocampus and striatum, brain regions involved in memory processing and motor coordination. These positive neurochemical effects, largely due to an increased activity of the limiting enzymes in monoamines synthesis, tryptophan hydroxylase and tyrosine hydroxylase, were accompanied by an improvement in cognitive and motor abilities in old rats. Altogether these findings suggest that α-tocopherol exhibits neuroprotective actions in old rats; thus, diets with α-tocopherol might represent a promising strategy to mitigate or delay the cognitive and motor decline associate with aging and related-diseases.

    Full Text Available Background and aim: Preliminary evaluation of a wild green oat extract (WGOE (Neuravena® ELFA®955, Frutarom, Switzerland revealed an acute cognitive benefit of supplementation. This study investigated whether regular daily WGOE supplementation would result in sustained cognitive improvements. Method: A 12-week randomised, double-blind, placebo-controlled cross-over trial of WGOE supplementation (1500 mg/day versus placebo was undertaken in 37 healthy adults aged 67 ± 0.8 years (mean ± SEM. Cognitive assessments included the Stroop colour-word test, letter cancellation, the rule-shift task, a computerised multi-tasking test battery and the trail-making task. All assessments were conducted in Week 12 and repeated in Week 24 whilst subjects were fasted and at least 18 h after taking the last dose of supplement. Result: Chronic WGOE supplementation did not affect any measures of cognition. Conclusion: It appears that the cognitive benefit of acute WGOE supplementation does not persist with chronic treatment in older adults with normal cognition. It remains to be seen whether sustained effects of WGOE supplementation may be more evident in those with mild cognitive impairment.

    Anger is among the earliest occurring symptoms of mental health, yet we know little about its developmental course. Further, no studies have examined whether youth with persistent anger are at an increased risk of exhibiting antisocial personality features in adulthood, or how cognitive control abilities may protect these individuals from developing such maladaptive outcomes. Trajectories of anger were delineated among 503 boys using annual assessments from childhood to middle adolescence (ages ∼7-14). Associations between these trajectories and features of antisocial personality in young adulthood (age ∼28) were examined, including whether cognitive control moderates this association. Five trajectories of anger were identified (i.e., childhood-onset, childhood-limited, adolescent-onset, moderate, and low). Boys in the childhood-onset group exhibited the highest adulthood antisocial personality features (e.g., psychopathy, aggression, criminal charges). However, boys in this group were buffered from these problems if they had higher levels of cognitive control during adolescence. Findings were consistent across measures from multiple informants, replicated across distinct time periods, and remained when controlling for general intelligence and prior antisocial behavior. This is the first study to document the considerable heterogeneity in the developmental course of anger from childhood to adolescence. As hypothesized, good cognitive control abilities protected youth with persistent anger problems from developing antisocial personality features in adulthood. Clinical implications and future directions are discussed. PMID:26618654

    Viral meningitis is considered to be a benign illness with only mild symptoms. In contrast to viral encephalitis and bacterial meningitis, the prognosis is usually good. However, retrospective studies have demonstrated that patients suffering from viral meningitis may experience cognitive impairment following the acute course of infection. Larger controlled studies are needed to elucidate the potential neuropsychiatric adverse outcome of viral meningitis.

    Full Text Available Abstract Background Coping with a chronic illness (CI challenges children's psychosocial functioning and wellbeing. Cognitive-behavioral intervention programs that focus on teaching the active use of coping strategies may prevent children with CI from developing psychosocial problems. Involvement of parents in the intervention program may enhance the use of learned coping strategies in daily life, especially on the long-term. The primary aim of the present study is to examine the effectiveness of a cognitive behavioral based group intervention (called 'Op Koers' 1 for children with CI and of a parallel intervention for their parents. A secondary objective is to investigate why and for whom this intervention works, in order to understand the underlying mechanisms of the intervention effect. Methods/design This study is a multicentre randomized controlled trial. Participants are children (8 to 18 years of age with a chronic illness, and their parents, recruited from seven participating hospitals in the Netherlands. Participants are randomly allocated to two intervention groups (the child intervention group and the child intervention combined with a parent program and a wait-list control group. Primary outcomes are child psychosocial functioning, wellbeing and child disease related coping skills. Secondary outcomes are child quality of life, child general coping skills, child self-perception, parental stress, quality of parent-child interaction, and parental perceived vulnerability. Outcomes are evaluated at baseline, after 6 weeks of treatment, and at a 6 and 12-month follow-up period. The analyses will be performed on the basis of an intention-to-treat population. Discussion This study evaluates the effectiveness of a group intervention improving psychosocial functioning in children with CI and their parents. If proven effective, the intervention will be implemented in clinical practice. Strengths and limitations of the study design are discussed

    Beta-amyloid (Aβ) oligomers contribute to the pathophysiology of Alzheimer disease (AD), and metabotropic glutamate receptor 5 (mGluR5) has been shown to act as a receptor for both Aβ oligomers and cellular prion proteins. Furthermore, the genetic deletion of mGluR5 in an APPswe/PS1ΔE9 mouse model of AD improves cognitive function and reduces Aβ plaques and Aβ oligomer concentrations. Here, we show that chronic administration of the orally bioavailable mGluR5-selective negative allosteric modulator CTEP, which is similar in structure, potency, and selectivity to Basimglurant (RO4917523), which is currently in phase II clinical development for major depressive disorder and fragile X syndrome, reverses cognitive decline in APPswe/PS1ΔE9 mice and reduces Aβ plaque deposition and soluble Aβ oligomer concentrations in both APPswe/PS1ΔE9 and 3xTg-AD male mice. These findings suggest that CTEP or its analogue Basimglutant might potentially be an effective therapeutic for the treatment of AD patients. PMID:27210751

    Intervention studies have found that psychotherapeutic interventions that explicitly integrate clients' spiritual and religious beliefs in therapy are as effective, if not more so, in reducing depression than those that do not for religious clients. However, few empirical studies have examined the effectiveness of religiously (vs. spiritually) integrated psychotherapy, and no manualized mental health intervention had been developed for the medically ill with religious beliefs. To address this gap, we developed and implemented a novel religiously integrated adaptation of cognitive-behavioral therapy (CBT) for the treatment of depression in individuals with chronic medical illness. This article describes the development and implementation of the intervention. First, we provide a brief overview of CBT. Next, we describe how religious beliefs and behaviors can be integrated into a CBT framework. Finally, we describe Religiously Integrated Cognitive Behavioral Therapy (RCBT), a manualized therapeutic approach designed to assist depressed individuals to develop depression-reducing thoughts and behaviors informed by their own religious beliefs, practices, and resources. This treatment approach has been developed for 5 major world religions (Christianity, Judaism, Islam, Buddhism, and Hinduism), increasing its potential to aid the depressed medically ill from a variety of religious backgrounds.

  16. Neuromuscular strain as a contributor to cognitive and other symptoms in chronic fatigue syndrome: hypothesis and conceptual model.

    Science.gov (United States)

    Rowe, Peter C; Fontaine, Kevin R; Violand, Richard L

    2013-01-01

    Individuals with chronic fatigue syndrome (CFS) have heightened sensitivity and increased symptoms following various physiologic challenges, such as orthostatic stress, physical exercise, and cognitive challenges. Similar heightened sensitivity to the same stressors in fibromyalgia (FM) has led investigators to propose that these findings reflect a state of central sensitivity. A large body of evidence supports the concept of central sensitivity in FM. A more modest literature provides partial support for this model in CFS, particularly with regard to pain. Nonetheless, fatigue and cognitive dysfunction have not been explained by the central sensitivity data thus far. Peripheral factors have attracted attention recently as contributors to central sensitivity. Work by Brieg, Sunderland, and others has emphasized the ability of the nervous system to undergo accommodative changes in length in response to the range of limb and trunk movements carried out during daily activity. If that ability to elongate is impaired-due to movement restrictions in tissues adjacent to nerves, or due to swelling or adhesions within the nerve itself-the result is an increase in mechanical tension within the nerve. This adverse neural tension, also termed neurodynamic dysfunction, is thought to contribute to pain and other symptoms through a variety of mechanisms. These include mechanical sensitization and altered nociceptive signaling, altered proprioception, adverse patterns of muscle recruitment and force of muscle contraction, reduced intra-neural blood flow, and release of inflammatory neuropeptides. Because it is not possible to differentiate completely between adverse neural tension and strain in muscles, fascia, and other soft tissues, we use the more general term "neuromuscular strain." In our clinical work, we have found that neuromuscular restrictions are common in CFS, and that many symptoms of CFS can be reproduced by selectively adding neuromuscular strain during the

    Body awareness has been proposed as one of the major mechanisms of mindfulness interventions, and it has been shown that chronic pain and depression are associated with decreased levels of body awareness. We investigated the effect of Mindfulness-Based Cognitive Therapy (MBCT) on body awareness in patients with chronic pain and comorbid active depression compared to treatment as usual (TAU; N = 31). Body awareness was measured by a subset of the Multidimensional Assessment of Interoceptive Awareness (MAIA) scales deemed most relevant for the population. These included: Noticing, Not-Distracting, Attention Regulation, Emotional Awareness, and Self-Regulation. In addition, pain catastrophizing was measured by the Pain Catastrophizing Scale (PCS). These scales had adequate to high internal consistency in the current sample. Depression severity was measured by the Quick Inventory of Depressive Symptomatology—Clinician rated (QIDS-C16). Increases in the MBCT group were significantly greater than in the TAU group on the “Self-Regulation” and “Not Distracting” scales. Furthermore, the positive effect of MBCT on depression severity was mediated by “Not Distracting.” These findings provide preliminary evidence that a mindfulness-based intervention may increase facets of body awareness as assessed with the MAIA in a population of pain patients with depression. Furthermore, they are consistent with a long hypothesized mechanism for mindfulness and emphasize the clinical relevance of body awareness. PMID:27445929

    Emerging evidence indicates that methamphetamine (MA) abuse can impact cardiovascular disease. In humans, MA abuse is associated with an increased risk of stroke as well as an earlier age at which the stroke occurs. However, little is known about how chronic daily MA exposure can impact ischemic outcome in either humans or animal models. In the present study, mice were injected with MA (10 mg/kg, i.p.) or saline once daily for 10 consecutive days. Twenty-four hours after the final injection, mice were subjected to transient middle cerebral artery occlusion (tMCAO) for one hour followed by reperfusion. Mice were tested for novel object memory at 96 h post-reperfusion, just prior to removal of brains for quantification of infarct volume using 2,3,5-Triphenyltetrazolium Chloride (TTC) staining. Mice treated with MA prior to tMCAO showed decreased object memory recognition and increased infarct volume compared to saline-treated mice. These findings indicate that chronic MA exposure can worsen both cognitive and morphological outcomes following cerebral ischemia. PMID:27021292

    Although the positive effects of different kinds of physical activity (PA) on cognitive functioning have already been demonstrated in a variety of studies, the role of cognitive engagement in promoting children's executive functions is still unclear. The aim of the current study was therefore to investigate the effects of two qualitatively different chronic PA interventions on executive functions in primary school children. Children (N = 181) aged between 10 and 12 years were assigned to either a 6-week physical education program with a high level of physical exertion and high cognitive engagement (team games), a physical education program with high physical exertion but low cognitive engagement (aerobic exercise), or to a physical education program with both low physical exertion and low cognitive engagement (control condition). Executive functions (updating, inhibition, shifting) and aerobic fitness (multistage 20-m shuttle run test) were measured before and after the respective condition. Results revealed that both interventions (team games and aerobic exercise) have a positive impact on children's aerobic fitness (4-5% increase in estimated VO2max). Importantly, an improvement in shifting performance was found only in the team games and not in the aerobic exercise or control condition. Thus, the inclusion of cognitive engagement in PA seems to be the most promising type of chronic intervention to enhance executive functions in children, providing further evidence for the importance of the qualitative aspects of PA.

  1. Neuropsychological sequelae of postradiation somnolence syndrome

    International Nuclear Information System (INIS)

    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

    AIM: To study the effects of centrophenoxine (CPH, meclofenoxate) on chronic cerebral hypoperfusion induced deficits in rats. METHODS: Chronic hypoperfusion in rats was performed by permanent bilateral ligation of the common carotid arteries. Morris water maze was used to measure spatial memory performance. Spectrophotometrical techniques were used to assay SOD, GPx activities, MDA content, TXB2, and 6-keto-PGF1α levels. Morphological change was examined by HE staining. The expression of Bax and p53 protein were assayed by immunohistochemistry analysis. RESULTS: Chronic hypoperfusion in rats resulted in spatial memory impairments shown by longer escape latency and shorter time spent in the target quadrant. These behavioral dysfunction were accompanied by increase in SOD and GPx activities, the content of MDA, the levels of pro-inflammatory mediators (TXB2, 6-keto-PGF1α), overexpression of Bax and P53 protein, and delayed degeneration of neurons in cortex and hippocampus. Oral administration of CPH (100 mg/kg, once per day for 37 d) markedly improved the memory impairment, reduced the increase in antioxidant enzyme activities, MDA content and the levels of pro-inflammatory mediators to their normal levels, and attenuated neuronal damage. CONCLUSION: The abilities of CPH to attenuate memory deficits and neuronal damage after ischemia may be beneficial in cerebrovascular type dementia.

Participants included were 273 adolescents (205 females and 68 males), aged 11 to 17 years with mixed chronic pain conditions and their parents, who were randomly assigned in a parallel-group design to Internet-delivered CBT (n = 138) or Internet-delivered Education (n = 135). Assessments were completed before treatment, immediately after treatment, and at 6-month follow-up. All data collection and procedures took place online. The primary analysis used linear growth models. Results demonstrated significantly greater reduction on the primary outcome of activity limitations from baseline to 6-month follow-up for Internet CBT compared with Internet education (b = -1.13, P = 0.03). On secondary outcomes, significant beneficial effects of Internet CBT were found on sleep quality (b = 0.14, P = 0.04), on reducing parent miscarried helping (b = -2.66, P = 0.007) and protective behaviors (b = -0.19, P = 0.001), and on treatment satisfaction (P values Internet CBT were found for parent-perceived impact (ie, reductions in depression, anxiety, self-blame about their adolescent's pain, and improvement in parent behavioral responses to pain). In conclusion, our Internet-delivered CBT intervention produced a number of beneficial effects on adolescent and parent outcomes, and could ultimately lead to wide dissemination of evidence-based psychological pain treatment for youth and their families.

    Full Text Available BACKGROUND Thromboembolism is a common and serious complication of joint replacement surgery. Cognitive decline occurs in 5-29% of patients, undergoing major orthopaedic surgery. Many studies show that systemic embolism may occur in the absence of venous-arterial shunts leading to cognitive dysfunction and neurological sequelae. METHODS We present two cases of neurological consequences occurring post bilateral TKR. Cases were successfully done under Combined Spinal Epidural Anaesthesia. Steroids were not used intraoperatively. RESULTS Both cases had neurological complications following completion of surgery. First case had posterior circulation TIA while the other had a right upper motor neuron facial palsy. CONCLUSION We suspect both as cases of cerebral fat microembolism in the absence of any venous-arterial shunt.

    Borg al inicio de la prueba (r = 0,747; p Chronic airway obstruction (CAO resulting from tuberculosis (TB sequelae (CAO-TB is a frequent condition in our population. However the information in the medical literature is scarce. The management of these patients usually follows guidelines for other illnesses such as chronic obstructive pulmonary disease (COPD or asthma. To better characterize CAO-TB, 25 patients with this condition that never smoked nor were diagnosed having asthma, were studied by means of spirometry, arterial blood gases and 6-minute walk test. Furthermore, they were compared with 12 COPD patients with similar FEV1 values. CAO-TB patients had history of tuberculosis 35 ± 11 years earlier, and all of them presented with lung scarring in one or both upper lobes. They were younger than COPD (58 ± 11 vs 69 ± 6 y.o.; p = 0.001 and females predominated over males (20/5 vs 2/10; p = 0.001. The FEV1/FVC ratio pre- and post-bronchodilator were higher in CAO-TB than in COPD patients (67% ± 12 vs 54% ± 9 pre; p = 0.001; 65% ± 14 vs 51% ± 7; p = 0.003 post, respectively. There were no differences in the remaining spirometric indices nor in arterial blood gases. The 6-min distance walked was comparable in both groups: 343 m (69% in CAO-TB and 361 m (76% in COPD. There were no differences in the oxygen saturation nor in heart rate neither at the beginning nor at the end of the 6-min walk test. However, CAO-TB patients had a higher respiratory rate at the beginning (22.7 ± 4.7 vs 19.8 ± 3.1 breath/min; p = 0.05 and at the end of the walk test (27.3 ± 6.7 vs 21.9 ± 3.3; p = 0.01 than COPD patients; although the Borg dyspnoea score was not different (1 ± 0,7 vs 1 ± 0.5 initial, 3 ± 1.5 vs 2.5 ± 0.8 final. Furthermore, a significant linear correlation between respiratory rate and Borg score was found both at the beginning (r = 0.747; p < 0.001 and at the end (r = 0.507; p = 0.01 of the walk test. In conclusion, CAO-TB patients are functionally comparable

    Chronic sleep restriction (CSR) induces neurobehavioral deficits in young and healthy people with a morning failure of sustained attention process. Testing both the kinetic of failure and recovery of different cognitive processes (i.e., attention, executive) under CSR and their potential links with subject’s capacities (stay awake, baseline performance, age) and with some biological markers of stress and anabolism would be useful in order to understand the role of sleep debt on human behavior. Twelve healthy subjects spent 14 days in laboratory with 2 baseline days (B1 and B2, 8 h TIB) followed by 7 days of sleep restriction (SR1-SR7, 4 h TIB), 3 sleep recovery days (R1–R3, 8 h TIB) and two more ones 8 days later (R12–R13). Subjective sleepiness (KSS), maintenance of wakefulness latencies (MWT) were evaluated four times a day (10:00, 12:00 a.m. and 2:00, 4:00 p.m.) and cognitive tests were realized at morning (8:30 a.m.) and evening (6:30 p.m.) sessions during B2, SR1, SR4, SR7, R2, R3 and R13. Saliva (B2, SR7, R2, R13) and blood (B1, SR6, R1, R12) samples were collected in the morning. Cognitive processes were differently impaired and recovered with a more rapid kinetic for sustained attention process. Besides, a significant time of day effect was only evidenced for sustained attention failures that seemed to be related to subject’s age and their morning capacity to stay awake. Executive processes were equally disturbed/recovered during the day and this failure/recovery process seemed to be mainly related to baseline subject’s performance and to their capacity to stay awake. Morning concentrations of testosterone, cortisol and α-amylase were significantly decreased at SR6-SR7, but were either and respectively early (R1), tardily (after R2) and not at all (R13) recovered.

    To date, there is yet no established effective treatment (medication or cognitive intervention) for post-traumatic brain injury (TBI) patients with chronic sequelae. Enriched environment (EE) has been recognized of importance in brain regulation, behaviour and physiology. Rodents reared in, or pre-exposed to EE, recovered better from brain insults. Using the concussive head trauma model of minimal TBI in mice, we evaluated the effect of transition to EE following a weight-drop (30g or 50g) induced mTBI on behavioural and cognitive parameters in mice in the Novel Object Recognition task, the Y- and the Elevated Plus mazes. In all assays, both mTBI groups (30g, 50g) housed in normal conditions were equally and significantly impaired 6 weeks post injury in comparison with the no-mTBI (pjuggling training and intensive cognitive stimulation.

  10. PI3K/Akt signal pathway involved in the cognitive impairment caused by chronic cerebral hypoperfusion in rats.

    Directory of Open Access Journals (Sweden)

    Yi Shu

    Full Text Available Chronic cerebral hypoperfusion (CCH is a common pathophysiological state that usually occurs in conditions such as vascular dementia and Alzheimer's disease, both of which are characterized by cognitive impairment. In previous studies we found that learning capacity and memory were gradually impaired with CCH, which altered the expression of synaptophysin, microtubule associated protein-2, growth associated protein-43, brain-derived neurotrophic factor, nerve growth factor, N-methyl-D-aspartate receptor subunit 1, cAMP response element-binding protein and tau hyperphosphorylation in the hippocampus. However, the molecular basis of cognitive impairment in CCH remains obscure. Here we explore the hypothesis that the phosphoinositide 3-kinase (PI3K/protein kinase B (Akt signal pathway is involved in this type of cognitive impairment. In order to determine if the expression of PI3K, Akt and phosphorylated Akt (p-Akt proteins are altered at different stages of CCH with differing levels of cognitive impairment. we performed permanent, bilateral occlusion of the common carotid arteries (2-VO to induce CCH. Adult male SD rats were randomly divided into sham-operated group, 2-VO 1 week group, 2-VO 4 weeks group and 2-VO 8 weeks group. Behavior tests were utilized to assess cognitive abilities, while western blots were utilized to evaluate protein expression. Rats in the 2-VO groups spent less time exploring novel objects than those in the sham-operated group, and the discrimination ratio of the 2-VO 8 weeks group and the sham-operated group were higher than chance (0.50. Escape latencies in the Morris water maze task in the 2-VO 1 week group were longer than those in the sham-operated group on day 4 and day 5, while escape latencies in the 2-VO 4 weeks group were longer than those in the sham-operated group from day 3 to day 5. Escape latencies in 2-VO 8 weeks group were longer than those in the sham-operated group from day 2 to day 5. NE (northeast

    The aim of this study was to examine whether amantadine (AMA), as a low-affinity noncompetitive N-methyl-d-aspartate (NMDA) receptor antagonist, is able to improve cognitive deficits caused by chronic stress in rats. Male Wistar rats were divided into four groups: control, control + AMA, stress and stress + AMA groups. The chronic stress model combined chronic unpredictable stress (CUS) with isolated feeding. Animals were exposed to CUS continued for 21 days. AMA (25 mg/kg) was administrated p.o. for 20 days from the 4th day of CUS to the 23rd. Weight and sucrose consumption were measured during model establishing period. Spatial memory was evaluated using the Morris water maze (MWM) test. Following MWM testing, both long-term potentiation (LTP) and depotentiation were recorded in the hippocampal CA1 region. NR2B and postsynaptic density protein 95 (PSD-95) proteins were measured by Western-blot analysis. AMA increased weight and sucrose consumption of stressed rats. Spatial memory and reversal learning in stressed rats were impaired relative to controls, whereas AMA significantly attenuated cognitive impairment. AMA also mitigated the chronic stress-induced impairment of hippocampal synaptic plasticity, in which both the LTP and depotentiation were significantly inhibited in stressed rats. Moreover, AMA enhanced the expression of hippocampal NR2B and PSD-95 in stressed rats. The data suggest that AMA may be an effective therapeutic agent for depression-like symptoms and associated cognitive disturbances.

  13. Neuropsychological sequelae of medulloblastoma in adults

    International Nuclear Information System (INIS)

    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

    Bone marrow mesenchymal stem cells (BMSCs) transplantation can ameliorate cognitive impairment in chronic ischemic brain injury, but the underlying mechanism is poorly understood. It is considered that the hippocampus holds the capabilities of memory consolidation and spatial navigation, and the gamma amino butyric acid (GABA)ergic system plays an important role in the control of learning and memory processes. Herein, we investigated whether transplantation of BMSCs could improve cognitive impairment via regulating the hippocampal GABAergic system in a rat model of chronic cerebral hypoperfusion. Animals treated with permanent bilateral occlusion of the common carotid arteries (two-vessel occlusion, 2VO) (a rat model of chronic cerebral hypoperfusion) received intravenous injections of BMSCs or saline as experimental group and control group I, the sham-operated rats received intravenous injections of BMSCs or saline as the sham group and control group II. Four weeks later, the Morris Water Maze was employed to evaluate the cognitive changes of each group, immunohistochemistry and western blotting was used to investigate the GABAergic system expression including GABA, glutamic acid decarboxylase 67 (GAD67) or GABA(B) receptor 1 (GABA(B)R1) in the hippocampus. Our results showed that the 2VO model presented decreased capacities of learning and memory and down-regulated the expression of GABA, GAD67 or GABA(B)R1 in the hippocampal CA1 subfield in comparison to the sham group (P<0.05), while administration of BMSCs (experimental group) manifested increased performances of learning sessions and probe tasks, as well as up-regulated expression of GABA, GAD67 or GABA(B)R1 compared with the control group I (P<0.05). Collectively, these findings suggest that transplantation of BMSCs is capable of improving cognitive impairment via up-regulating the hippocampal GABAergic system in a rat model of chronic cerebral hypoperfusion. Hence, BMSCs transplantation could serve as an

    The treatment of patients with chronic pain disorders is complex. In the rehabilitation of these patients, coping with chronic pain is seen as important. The aim of this study was to explore the meaning of attachment and mindfulness-based cognitive therapy (CT) among patients with chronic pain and psychiatric co-morbidity. A phenomenological approach within a lifeworld perspective was used. In total, 10 patients were interviewed after completion of 7- to 13-month therapy. The findings reveal that the therapy and the process of interaction with the therapist were meaningful for the patients' well-being and for a better management of pain. During the therapy, the patients were able to initiate a movement of change. Thus, CT with focus on attachment and mindfulness seems to be of value for these patients. The therapy used in this study was adjusted to the patients' special needs, and a trained psychotherapist with a special knowledge of patients with chronic pain might be required.

  16. Neuromuscular strain as a contributor to cognitive and other symptoms in Chronic Fatigue Syndrome: Hypothesis and conceptual model.

    Peter C. Rowe

    2013-05-01

    Full Text Available Individuals with chronic fatigue syndrome (CFS have heightened sensitivity and increased symptoms following various physiologic challenges, such as orthostatic stress, physical exercise, and cognitive challenges. Similar heightened sensitivity to the same stressors in fibromyalgia (FM has led investigators to propose that these findings reflect a state of central sensitivity. A large body of evidence supports the concept of central sensitivity in FM. A more modest literature provides partial support for this model in CFS, particularly with regard to pain. Nonetheless, fatigue and cognitive dysfunction have not been explained by the central sensitivity data thus far. Peripheral factors have attracted attention recently as contributors to central sensitivity. Work by Brieg, Sunderland, and others has emphasized the ability of the nervous system to undergo accommodative changes in length in response to the range of limb and trunk movements carried out during daily activity. If that ability to elongate is impaired—due to movement restrictions in tissues adjacent to nerves, or due to swelling or adhesions within the nerve itself—the result is an increase in mechanical tension within the nerve. This adverse neural tension, also termed neurodynamic dysfunction, is thought to contribute to pain and other symptoms through a variety of mechanisms. These include mechanical sensitization and altered nociceptive signaling, altered proprioception, adverse patterns of muscle recruitment and force of muscle contraction, reduced intra-neural blood flow, and release of inflammatory neuropeptides. Because it is not possible to differentiate completely between adverse neural tension and strain in muscles, fascia, and other soft tissues, we use the more general term neuromuscular strain. In our clinical work, we have found that neuromuscular restrictions are common in CFS, and that many symptoms of CFS can be reproduced by selectively adding neuromuscular strain

Methods  There were 22-week-old wild-type C57BL/6 male mice (control group, N = 15 and APP/PS-1 double transgenic male mice [N = 27: AD group (N = 13 and AD + CUMS group (N = 14] tested in this study. Morris water maze test was used to evaluate spatial learning and memory of the mice. Amyloid deposition in the hippocampus was determined by Congo red staining. The ultrastructure of neurons in hippocampal CA1 region was observed by transmission electron microscope (TEM.  Results  Compared with control group, AD + CUMS group had significantly longer fifth-day escape latency [(33.14 ± 14.37 s vs (21.22 ± 12.16 s; t = -2.701, P = 0.045], and significantly shortened time spent in platform quadrant [(9.74±1.35 s vs (15.02 ± 1.33 s; t = 2.639, P = 0.012] in Morris water maze test. Compared with AD group, the percentage of amyloid plaque area in hippocampal area was increased in AD + CUMS group [(0.59 ± 0.03% vs (0.04 ± 0.03%; t = -2.900, P = 0.005]. The ultrastructure of hippocampal neurons in AD group was slightly damaged: cellular membrane was intact; cell matrix was uniform; intracelluar lipofuscin could be seen; the structure of nucleus and nuclear membrane had no obvious changes; mild fusion of cristae and membrane was seen in mitochondria; Golgi apparatus was partially indistinct; endoplasmic reticulum was mildly expanded. The ultrastructure of hippocampal neurons in AD + CUMS group was obviously damaged, including blurred cell membrane, reduced low-density and high-density granules in cytoplasm, uneven cell matrix, reduced number of organelles, lipofuscin and autophagosome deposition, obvious condensation of chromatin distributing over

    Fifteen adults with multiple sclerosis were given 16 sessions of treatment for chronic pain that included 4 sessions each of 4 different treatment modules: (a) an education control intervention; (b) self-hypnosis training (HYP); (c) cognitive restructuring (CR); and (d) a combined hypnosis-cognitive restructuring intervention (CR-HYP). The findings supported the greater beneficial effects of HYP, relative to CR, on average pain intensity. The CR-HYP treatment appeared to have beneficial effects greater than the effects of CR and HYP alone. Future research examining the efficacy of an intervention that combines CR and HYP is warranted.

    The present study examined the incidence of chronic stress in business executives (109 subjects: 75 male and 34 female) and its relationship with cortisol levels, cognitive performance, and autonomic nervous system (ANS) reactivity after an acute mental stressor. Blood samples were collected from the subjects to measure cortisol concentration. After the sample collection, the subjects completed the Lipp Inventory of Stress Symptoms for Adults and the Stroop Color-Word Test to evaluate stress and cognitive performance levels, respectively. Saliva samples were collected prior to, immediately after, and five minutes after the test. The results revealed that 90.1% of the stressed subjects experienced stress phases that are considered chronic stress. At rest, the subjects with chronic stress showed higher cortisol levels, and no gender differences were observed. No differences were found between the stressed and non-stressed subjects regarding salivary amylase activity prior to test. Chronic stress also impaired performance on the Stroop test, which revealed higher rates of error and longer reaction times in the incongruent stimulus task independently of gender. For the congruent stimulus task of the Stroop test, the stressed males presented a higher rate of errors than the non-stressed males and a longer reaction time than the stressed females. After the acute mental stressor, the non-stressed male group showed an increase in salivary alpha-amylase activity, which returned to the initial values five minutes after the test; this ANS reactivity was not observed in the chronically stressed male subjects. The ANS responses of the non-stressed vs stressed female groups were not different prior to or after the Stroop test. This study is the first to demonstrate a blunted reactivity of the ANS when male subjects with chronic psychological stress were subjected to an acute mental stressor, and this change could contribute to impairments in cognitive performance.

Chronic stress also impaired performance on the Stroop test, which revealed higher rates of error and longer reaction times in the incongruent stimulus task independently of gender. For the congruent stimulus task of the Stroop test, the stressed males presented a higher rate of errors than the non-stressed males and a longer reaction time than the stressed females. After the acute mental stressor, the non-stressed male group showed an increase in salivary alpha-amylase activity, which returned to the initial values five minutes after the test; this ANS reactivity was not observed in the chronically stressed male subjects. The ANS responses of the non-stressed vs stressed female groups were not different prior to or after the Stroop test. This study is the first to demonstrate a blunted reactivity of the ANS when male subjects with chronic psychological stress were subjected to an acute mental stressor, and this change could contribute to impairments in cognitive

    The present study examined the incidence of chronic stress in business executives (109 subjects: 75 male and 34 female) and its relationship with cortisol levels, cognitive performance, and autonomic nervous system (ANS) reactivity after an acute mental stressor. Blood samples were collected from the subjects to measure cortisol concentration. After the sample collection, the subjects completed the Lipp Inventory of Stress Symptoms for Adults and the Stroop Color-Word Test to evaluate stress and cognitive performance levels, respectively. Saliva samples were collected prior to, immediately after, and five minutes after the test. The results revealed that 90.1% of the stressed subjects experienced stress phases that are considered chronic stress. At rest, the subjects with chronic stress showed higher cortisol levels, and no gender differences were observed. No differences were found between the stressed and non-stressed subjects regarding salivary amylase activity prior to test. Chronic stress also impaired performance on the Stroop test, which revealed higher rates of error and longer reaction times in the incongruent stimulus task independently of gender. For the congruent stimulus task of the Stroop test, the stressed males presented a higher rate of errors than the non-stressed males and a longer reaction time than the stressed females. After the acute mental stressor, the non-stressed male group showed an increase in salivary alpha-amylase activity, which returned to the initial values five minutes after the test; this ANS reactivity was not observed in the chronically stressed male subjects. The ANS responses of the non-stressed vs stressed female groups were not different prior to or after the Stroop test. This study is the first to demonstrate a blunted reactivity of the ANS when male subjects with chronic psychological stress were subjected to an acute mental stressor, and this change could contribute to impairments in cognitive performance.

  2. RELIABILITY OF PHYSIOLOGICAL, PSYCHOLOGICAL AND COGNITIVE VARIABLES IN CHRONIC FATIGUE SYNDROME AND THE ROLE OF GRADED EXERCISE

    Full Text Available The objective of this study was to assess variability in symptoms and physical capabilities in chronic fatigue syndrome (CFS participants both before and after a graded exercise intervention. Sixty-one CFS subjects participated in a 12-week randomized controlled trial of either graded exercise (n =32 or relaxation/stretching therapy (n = 29. Specific physiological, psychological and cognitive variables were assessed once weekly over a four-week period both prior to and after the intervention period. All scores were assessed for reliability using an intraclass correlation coefficient (ICC. Apart from mental and physical fatigue, baseline ICC scores for all variables assessed were moderately to highly reliable, indicating minimal variability. Baseline scores for mental and physical fatigue were of questionable reliability, indicating a fluctuating nature to these symptoms (R1 = 0.64 and 0.60, respectively. Variability in scores for mental fatigue was reduced after graded exercise to an acceptable classification (R1 = 0.76. Results from this study support a variable nature to the symptoms of mental and physical fatigue only. Consequently, in order to more accurately report the nature of mental and physical fatigue in CFS, future studies should consider using repeated-measures analysis when assessing these symptoms. Graded exercise resulted in the reclassification of scores for mental fatigue from questionable to acceptable reliability

    Objective: To explored the effects of puerarin on cognitive deficits and tissue oxidative stress and the underlying mechanisms. Methods: 6 to 8 week old male Wistar rats were adopted as experimental animals. Morris water maze (MWM) test was adopted to test the learning and memory function of rats. MDA, glutathione peroxidase and total thiol assessment was done to reflect the oxidative stress in the brain tissue. Cell Counting Kit-8 (CCK8) and flow cytometry (FCM) were performed to examine the cell viability and apoptosis rate. Reactive oxygen species (ROS) generation was determined by the 2’, 7’-dichlorofluorescein diacetate (DCFH-DA) assay. qPCR and Western blot (WB) were adopted to test the molecular function mechanisms of puerarin. Results: Our results indicated a protective effect of puerarin on vascular dementia. Administration of puerarin could improve the impaired learning and memory function. The levels of MDA were partially decreased by puerarin. The levels of glutathione peroxidase and total thiol were partially restored. Cell viability was improved in a dose-dependent pattern (P < 0.05). Cell apoptosis rate was reduced in a dose-dependent pattern (P < 0.05). Puerarin could scavenge ROS generation induced by pre-treatment of hydrogen peroxide. The results showed up-regulated levels of Nrf2, FoxO1, FoxO3 and FoxO4 (P < 0.05). Conclusion: Puerarin is protective on the vascular dementia by reducing oxidative stress and improving learning and memory functions. On the molecular level, Nrf2, FoxO1, FoxO3 and FoxO4 were up regulated by puerarin. PMID:26191159

    Full Text Available Aim. To evaluate the efficacy of cognitive behavioral therapy (CBT-I in chronic insomnia treatment. Method. 236 patients with ICD-10 nonorganic insomnia were assigned to group CBT-I (6 sessions, 6-10 patients. From this pool, 72 participants with no history of other psychiatric or sleep disorders conditions were selected. Eventually, 51 patients (40 female, mean age: 54.6±13.9y, mean insomnia duration: 7±6.3y and 51 matched healthy controls (mean age: 55.4±14.3y completed the study. Outcomes in the insomnia group at baseline and post-treatment were compared to control group. Subjects underwent sleep diary, the Athens Insomnia Scale (AIS, the Beck Depression Inventory (BDI, the Ford Insomnia Response to Stress Test (FIRST, the SF-36 questionnaire and the State-Trait Anxiety Inventory (STAI. Results. At baseline, groups differed significantly in most dependent variables. At post-treatment, a substantial improvement in all sleep parameters was observed in insomnia group: sleep latency, number of awakenings, wake time after sleep onset, sleep time, sleep efficiency, sleep quality and frequency of hypnotic use. These outcomes were accompanied by lower AIS and FIRST scores, reductions of depression and anxiety symptoms, and improved energy and social functioning ratings. All changes were maintained during the 3-month follow-up. Only 10/51 patients had no clinically meaningful improvement at any post-treatment time points. After the therapy, patients did not differ significantly from good sleepers in number of awakenings, sleep quality, feeling in the morning, depression and anxiety symptoms, and quality of life related to mental health. Conclusions. The CBT-I produced a sustained, clinically meaningful improvement in nocturnal sleep and daytime functioning.

    Single doses of resveratrol have previously been shown to increase cerebral blood flow (CBF) with no clear effect on cognitive function or mood in healthy adults. Chronic resveratrol consumption may increase the poor bioavailability of resveratrol or otherwise potentiate its psychological effects. In this randomised, double-blind, placebo-controlled, parallel-groups study, a total of sixty adults aged between 18 and 30 years received either placebo or resveratrol for 28 d. On the 1st and 28th day of treatment, the performance of cognitively demanding tasks (serial subtractions, rapid visual information processing and 3-Back) (n 41 complete data sets) was assessed, alongside blood pressure (n 26) and acute (near-IR spectroscopy (NIRS)) and chronic (transcranial Doppler) measures of CBF (n 46). Subjective mood, sleep quality and health questionnaires were completed at weekly intervals (n 53/54). The results showed that the cognitive effects of resveratrol on day 1 were restricted to more accurate but slower serial subtraction task performance. The only cognitive finding on day 28 was a beneficial effect of resveratrol on the accuracy of the 3-Back task before treatment consumption. Subjective ratings of 'fatigue' were significantly lower across the entire 28 d in the resveratrol condition. Resveratrol also resulted in modulation of CBF parameters on day 1, as assessed by NIRS, and significantly increased diastolic blood pressure on day 28. Levels of resveratrol metabolites were significantly higher both before and after the day's treatment on day 28, in comparison with day 1. These results confirm the acute CBF effects of resveratrol and the lack of interpretable cognitive effects. PMID:26344014

    Full Text Available Abstract Background Most people with a spinal cord injury rate neuropathic pain as one of the most difficult problems to manage and there are no medical treatments that provide satisfactory pain relief in most people. Furthermore, psychosocial factors have been considered in the maintenance and aggravation of neuropathic spinal cord injury pain. Psychological interventions to support people with spinal cord injury to deal with neuropathic pain, however, are sparse. The primary aim of the CONECSI (COping with NEuropathiC Spinal cord Injury pain trial is to evaluate the effects of a multidisciplinary cognitive behavioural treatment programme on pain intensity and pain-related disability, and secondary on mood, participation in activities, and life satisfaction. Methods/Design CONECSI is a multicentre randomised controlled trial. A sample of 60 persons with chronic neuropathic spinal cord injury pain will be recruited from four rehabilitation centres and randomised to an intervention group or a waiting list control group. The control group will be invited for the programme six months after the intervention group. Main inclusion criteria are: having chronic (> 6 months neuropathic spinal cord injury pain as the worst pain complaint and rating the pain intensity in the last week as 40 or more on a 0-100 scale. The intervention consists of educational, cognitive, and behavioural elements and encompasses 11 sessions over a 3-month period. Each meeting will be supervised by a local psychologist and physical therapist. Measurements will be perfomed before starting the programme/entering the control group, and at 3, 6, 9, and 12 months. Primary outcomes are pain intensity and pain-related disability (Chronic Pain Grade questionnaire.

    Pseudoaneurysm is an uncommon sequela of infective endocarditis. We treated a 44-year-old man who had an active case of group B streptococcal infective endocarditis of the aortic valve despite no evidence of valvular dysfunction or vegetation on his initial transesophageal echocardiogram. After completing 6 weeks of intravenous antibiotic therapy, the patient developed a sinus of Valsalva pseudoaneurysm and severe aortic regurgitation caused by partial detachment of the left coronary cusp. We used a pericardial patch to close the pseudoaneurysm and repair the coronary cusp. This case shows the importance of routine clinical follow-up evaluation in infective endocarditis, even after completion of antibiotic therapy. Late sequelae associated with infective endocarditis or its therapy include recurrent infection, heart failure caused by valvular dysfunction (albeit delayed), and antibiotic toxicity such as aminoglycoside-induced nephropathy and vestibular toxicity.

    Acute viral bronchiolitis (AVB) is a common disease found throughout the world. Various aspects of it are being studied: its epidemiology, diagnosis, prognosis and treatment. Most of these studies are being conducted in developed countries, with only a few taking place in developing countries. Risk factors such as poor nutrition, an adverse environment and early weaning should be studied where these features are common. Treatment aspects such as cost-effectiveness in low income settings need further study. Use of ribavirin and respiratory syncytial virus (RSV)-immunoglobulin are good examples. Post-bronchiolitic sequelae also need to be studied in low income countries. There is evidence that bronchiolitis obliterans is unusually frequent in some Latin-American countries such as Argentina and Brazil. It will be helpful to undertake combined studies in countries with the same socio-economics, investigating the preventive and management aspects of AVB and its sequelae to reduce the morbidity and mortality.

    As the massive outbreak of Ebola virus disease (EVD) in west Africa wanes, it has become increasingly clear that thousands of survivors have many sequelae, some of which might be very severe, such as arthritis and vision-threatening uveitis. The mental health effects of EVD on survivors and other family and community members is similarly profound. Furthermore, it is increasingly being recognised that Ebola virus might persist for weeks or months in selected body compartments of survivors, most notably in the semen of men, bringing risk of renewed transmission where it has previously been eliminated. These challenges to EVD survivors constitute a new emergency in terms of addressing individual patient need and to control the disease spread. In this Review, we assess what is known regarding the sequelae of EVD, including possible delayed virus clearance. We discuss some of the key challenges regarding the provision of care to survivors and implementation of necessary future research. PMID:27020309

    The prevalence of distress in aspects of perceived health and its relation to involvement of poliomyelitis sequelae were studied with the Nottingham Health Profile (NHP) in 113 outpatients (mean age 57 years). The leisure and employment situation was also recorded. Most distress was found in the NHP dimensions physical mobility, pain and energy, and least distress in social isolation. Most health-related problems were reported in housework, employment and leisure. Three-quarters of the persons were satisfied with their leisure, although many of them had problems. Fifty-nine per cent of the subjects of working age were in gainful employment, and no difference in employment rate due to the distribution of polio involvement was found. In comparison with norm values for the respective age groups, the subjects with poliomyelitis sequelae aged below 45 and 45-65 years had more distress in a larger number of NHP dimensions than older subjects.

    Schwartz, S M; Gramling, S E

    1997-07-01

    Most well-accepted etiological models of facial pain (e.g., temporomandibular disorders and headache) implicate emotional distress as an important factor in the development and maintenance of pain. Data exists to support the notion that some facial pain sufferers are more emotionally distressed than no pain controls. However, many of these dependent measures of emotional distress are either lengthy assessment batteries, lack clear cut psychotherapeutic treatment implications, or focus exclusively on pain related sequela. As cognitive-behavioral interventions become more integrated into the treatment of chronic pain conditions, including various facial pain conditions, it becomes more imperative that the tools used to assess psychological functioning provide the clinician with specific cognitive/behavioral targets for change. The purpose of this study was to assess the degree to which symptomatic treatment seeking facial pain sufferers (N = 25), symptomatic non-treatment seeking facial pain sufferers (N = 48), and healthy pain-free controls (N = 70) differed on the Rational Beliefs Inventory (RBI). The RBI is a reliable, valid questionnaire assessing rational beliefs that are operationalized within a Rational Emotive Therapy (RET) framework. RET is a cognitive-behavioral treatment paradigm that focuses on how an individual's maladaptive cognitive errors or distortions exacerbate emotional distress. Group differences were assessed using a oneway Analysis of Covariance (ANCOVA) with the total RBI score serving as the dependent measure, and a Multivariate Analysis of Covariance (MANCOVA) using individual RBI belief subscales as dependent measures. These results indicated that groups differed significantly on the total score and several of the individual belief subscales. These findings indicated that facial pain sufferers generally hold maladaptive beliefs that may be of clinical significance for cognitive/behavioral treatment approaches.

    Objective: To evaluate the ameliorative effect of melatonin on sub-chronic chlorpyrifos (CPF) and cypermethrin (CYP)-evoked cognitive changes in male Wistar rats. Methods:Fifty adult male Wistar rats, divided into five groups of ten rats each, were used for the study. Groups 1 and II were given distilled water and soya oil (2 mL/kg) respectively. Group III was administered with melatonin at 0.5 mg/kg only. Group IV was administered with CPF [7.96 mg/kg (1/10th LD50)] and CYP [29.6 mg/kg (1/10th LD50)] , and Group V was administered with CPF [7.96 mg/kg (1/10th LD50)] and CYP [29.6 mg/kg (1/10th LD50)] 30 min after melatonin (0.5 mg/kg). The regimens were administered by gavage once daily for 12 weeks. Thereafter, cognitive performances were determined and the brain was evaluated for malonaldehyde concentration. Results: CPF and CYP induced cognitive deficits and increased brain malonaldehyde concentration, which were all ameliorated by melatonin.Conclusion: Cognitive deficits elicited by CPF and CYP was mitigated by melatonin due to its antioxidant property.

    Full Text Available Abstract Background Patients with chronic fatigue syndrome experience extreme fatigue, which often leads to substantial limitations of occupational, educational, social and personal activities. Currently, there is no consensus regarding the treatment. Patients try many different therapies to overcome their fatigue. Although there is no consensus, cognitive behavioural therapy is seen as one of the most effective treatments. Little is known about multidisciplinary rehabilitation treatment, a combination of cognitive behavioural therapy with principles of mindfulness, gradual increase of activities, body awareness therapy and pacing. The difference in effectiveness and cost-effectiveness between multidisciplinary rehabilitation treatment and cognitive behavioural therapy is as yet unknown. The FatiGo (Fatigue-Go trial aims to compare the effects of both treatment approaches in outpatient rehabilitation on fatigue severity and quality of life in patients with chronic fatigue syndrome. Methods One hundred twenty patients who meet the criteria of chronic fatigue syndrome, fulfil the inclusion criteria and sign the informed consent form will be recruited. Both treatments take 6 months to complete. The outcome will be assessed at 6 and 12 months after the start of treatment. Two weeks after the start of treatment, expectancy and credibility will be measured, and patients will be asked to write down their personal goals and score their current performance on these goals on a visual analogue scale. At 6 and 14 weeks after the start of treatment, the primary outcome and three potential mediators—self-efficacy, causal attributions and present-centred attention-awareness—will be measured. Primary outcomes are fatigue severity and quality of life. Secondary outcomes are physical activity, psychological symptoms, self-efficacy, causal attributions, impact of disease on emotional and physical functioning, present-centred attention-awareness, life

  3. The Putative Role of Viruses, Bacteria, and Chronic Fungal Biotoxin Exposure in the Genesis of Intractable Fatigue Accompanied by Cognitive and Physical Disability.

    2016-05-01

    Patients who present with severe intractable apparently idiopathic fatigue accompanied by profound physical and or cognitive disability present a significant therapeutic challenge. The effect of psychological counseling is limited, with significant but very slight improvements in psychometric measures of fatigue and disability but no improvement on scientific measures of physical impairment compared to controls. Similarly, exercise regimes either produce significant, but practically unimportant, benefit or provoke symptom exacerbation. Many such patients are afforded the exclusionary, non-specific diagnosis of chronic fatigue syndrome if rudimentary testing fails to discover the cause of their symptoms. More sophisticated investigations often reveal the presence of a range of pathogens capable of establishing life-long infections with sophisticated immune evasion strategies, including Parvoviruses, HHV6, variants of Epstein-Barr, Cytomegalovirus, Mycoplasma, and Borrelia burgdorferi. Other patients have a history of chronic fungal or other biotoxin exposure. Herein, we explain the epigenetic factors that may render such individuals susceptible to the chronic pathology induced by such agents, how such agents induce pathology, and, indeed, how such pathology can persist and even amplify even when infections have cleared or when biotoxin exposure has ceased. The presence of active, reactivated, or even latent Herpes virus could be a potential source of intractable fatigue accompanied by profound physical and or cognitive disability in some patients, and the same may be true of persistent Parvovirus B12 and mycoplasma infection. A history of chronic mold exposure is a feasible explanation for such symptoms, as is the presence of B. burgdorferi. The complex tropism, life cycles, genetic variability, and low titer of many of these pathogens makes their detection in blood a challenge. Examination of lymphoid tissue or CSF in such circumstances may be warranted. PMID

    Full Text Available The treatment of patients with chronic pain disorders is complex. In the rehabilitation of these patients, coping with chronic pain is seen as important. The aim of this study was to explore the meaning of attachment and mindfulness-based cognitive therapy (CT among patients with chronic pain and psychiatric co-morbidity. A phenomenological approach within a lifeworld perspective was used. In total, 10 patients were interviewed after completion of 7- to 13-month therapy. The findings reveal that the therapy and the process of interaction with the therapist were meaningful for the patients’ well-being and for a better management of pain. During the therapy, the patients were able to initiate a movement of change. Thus, CT with focus on attachment and mindfulness seems to be of value for these patients. The therapy used in this study was adjusted to the patients’ special needs, and a trained psychotherapist with a special knowledge of patients with chronic pain might be required.

    It has been demonstrated that selective unilateral surgical ablation of posteroventral globus pallidus interna relieves the movement disorders associated with advanced Parkinson's disease, without necessarily incurring the executive cognitive sequelae that have been observed following gross pathological lesions to this brain region. This finding is consistent with established theory that underlying neuronal circuitry is functionally segregated into parallel cortico-striatal-pallidal-thalamo-cortical 'loops'. We have studied a series of 12 patients with advanced Parkinson's disease at baseline, and then following bilateral pallidotomy, with a battery of neuropsychological tests including the Cambridge Neuro psychological Test Automated Battery. We identified a selective and universal loss of individual patients' ability to shift attention to novel dimensions in a test of abstract rule-learning following surgery, which was not reliably associated with any other change in cognition, personality, mood or medication. This finding is rare in its specificity and has implications for theoretical models of the functional architecture and pathophysiology of the globus pallidus, and the clinical practice of pallidotomy.

  6. Effect of aerobic exercise training and cognitive behavioural therapy on reduction of chronic fatigue in patients with facioscapulohumeral dystrophy: protocol of the FACTS-2-FSHD trial

    Full Text Available Abstract Background In facioscapulohumeral dystrophy (FSHD muscle function is impaired and declines over time. Currently there is no effective treatment available to slow down this decline. We have previously reported that loss of muscle strength contributes to chronic fatigue through a decreased level of physical activity, while fatigue and physical inactivity both determine loss of societal participation. To decrease chronic fatigue, two distinctly different therapeutic approaches can be proposed: aerobic exercise training (AET to improve physical capacity and cognitive behavioural therapy (CBT to stimulate an active life-style yet avoiding excessive physical strain. The primary aim of the FACTS-2-FSHD (acronym for Fitness And Cognitive behavioural TherapieS/for Fatigue and ACTivitieS in FSHD trial is to study the effect of AET and CBT on the reduction of chronic fatigue as assessed with the Checklist Individual Strength subscale fatigue (CIS-fatigue in patients with FSHD. Additionally, possible working mechanisms and the effects on various secondary outcome measures at all levels of the International Classification of Functioning, Disability and Health (ICF are evaluated. Methods/Design A multi-centre, assessor-blinded, randomized controlled trial is conducted. A sample of 75 FSHD patients with severe chronic fatigue (CIS-fatigue ≥ 35 will be recruited and randomized to one of three groups: (1 AET + usual care, (2 CBT + usual care or (3 usual care alone, which consists of no therapy at all or occasional (conventional physical therapy. After an intervention period of 16 weeks and a follow-up of 3 months, the third (control group will as yet be randomized to either AET or CBT (approximately 7 months after inclusion. Outcomes will be assessed at baseline, immediately post intervention and at 3 and 6 months follow up. Discussion The FACTS-2-FSHD study is the first theory-based randomized clinical trial which evaluates the effect and the

    Five painful (group A) and five symptomless (group B) hips in nine patients with late sequelae of Perthes` disease were studied with plain radiography and magnetic resonance imaging (MRI) in order to correlate MRI findings with symptomatology. The unaffected hips were also studied. In group A hips, poor congruence of the articular cartilage surfaces was present in three of five cases, whereas good congruence was found in all group B hips. In one spherical but painful hip (group A), MRI revealed a protuberance in the anterolateral cartilage of the femoral head. The joint cartilage in group A and B hips was, on average, 0.5 and 1.5 mm thicker, respectively, than the cartilage in the unaffected hips. The lateral joint capsule was, on average, 3.0 mm thicker in group A hips than in the unaffected hips (P < 0.05), which possibly reflects reactive changes due to chronic irritation in the painful hips. The mean joint capsule thickness differed by only 0.5 mm between the unaffected and group B hips. Mean anterior acetabular coverage by MRI was 97 % in group A and 98 % in group B, while in the unaffected hips mean anterior coverage was 102 %. In an aspherical painful hip, MRI revealed a juxta-articular cyst not visible by radiography. A symptomless intra-articular fragment, due to osteochondritis dissecans, was well visualized with MRI. MRI is recommended for evaluation of pain in hips with late sequelae of Perthes` disease. It may show abnormalities in bony structures, as well as in joint capsule and cartilage. (orig.).

    2009-02-01

    Noma is a gangrenous disease leading to destruction of soft and hard tissue of the face. It mainly affects young poor children with poor oral care. Without treatment noma is fatal in 70 to 90% of cases. In survivors, esthetic and functional sequelae are severe. Emergency intravenous antibiotherapy improves survival but restoration of the face requires reconstructive surgery. Different surgical techniques with various degrees of complexity and reliability have been proposed. The purpose of this article is to describe the nasogenal flap technique. This simple, single-stage technique is well suited to conditions in Africa.

Materials and methods: A comparative study was carried out on patients with CHF to examine the effect of combined treatment, including the experimental application of FSCs, on the morphofunctional parameters of the left ventricle and cognitive functions. Patients were examined before FSC treatment (FSCT, and 1 month, 3 months, and 6 months after treatment. The control group consisted of 20 CHF patients of similar age, sex, and New York Heart Association class. Results: It has been proven that FSCs positively affect objective and subjective clinical parameters. A significant reduction of serum type B brain natriuretic peptide was reported as early as 1 month after treatment. Significant increases in the left ventricle ejection fraction and decreases of the end diastolic volume were observed 6 months after treatment. Cognitive performance tests showed improvements on the Mini-Mental State Examination and Frontal Assessment Battery (conceptualization, mental flexibility, programming, sensitivity to interference, inhibitory control, and environmental autonomy scales. The treatment resulted in significant improvements in the general score and across all cognitive areas of the Mini-Mental State Examination (recall, orientation, attention, calculation, and complex commands after 3 months, and significant improvements across all Frontal Assessment Battery areas after 6 months. In the control group, these scores showed significant increases only at 6 months after the treatment. In the study group, depression was significantly reduced within 1 month after treatment versus 3 months in the control

    2011-08-01

    Full Text Available Abstract Background Effective treatment strategies for chronic depression are urgently needed since it is not only a common and particularly disabling disorder, but is also considered treatment resistant by most clinicians. There are only a few studies on chronic depression indicating that traditional psycho- and pharmacological interventions are not as effective as in acute, episodic depression. Current medications are no more effective than those introduced 50 years ago whereas the only psychotherapy developed specifically for the subgroup of chronic depression, the Cognitive Behavioral Analysis System of Psychotherapy (CBASP, faired well in one large trial. However, CBASP has never been directly compared to a non-specific control treatment. Methods/Design The present article describes the study protocol of a multisite parallel-group randomized controlled trial in Germany. The purpose of the study is to estimate the efficacy of CBASP compared to supportive psychotherapy in 268 non-medicated early-onset chronically depressed outpatients. The intervention includes 20 weeks of acute treatment with 24 individual sessions followed by 28 weeks of continuation treatment with another 8 sessions. Depressive symptoms are evaluated 20 weeks after randomisation by means of the 24-item Hamilton Rating Scale of Depression (HRSD. Secondary endpoints are depressive symptoms after 12 and 48 weeks, and remission after 12, 20, and 48 weeks. Primary outcome will be analysed using analysis of covariance (ANCOVA controlled for pre-treatment scores and site. Analyses of continuous secondary variables will be performed using linear mixed models. For remission rates, chi-squared tests and logistic regression will be applied. Discussion The study evaluates the comparative effects of a disorder-specific psychotherapy and a well designed non-specific psychological approach in the acute and continuation treatment phase in a large sample of early-onset chronically

  13. A combined robotic and cognitive training for locomotor rehabilitation: Evidences of cerebral functional reorganization in two chronic traumatic brain injured patients

    2011-11-01

    Full Text Available It has been demonstrated that automated locomotor training can improve walking capabilities in spinal cord-injured subjects but its effectiveness on brain damaged patients has not been well established. A possible explanation of the discordant results on the efficacy of robotic training in patients with cerebral lesions could be that these patients, besides stimulation of physiological motor patterns through passive leg movements, also need to train the cognitive aspects of motor control. Indeed, another way to stimulate cerebral motor areas in paretic patients is to use the cognitive function of motor imagery. A promising possibility is thus to combine sensorimotor training with the use of motor imagery. The aim of this paper is to assess changes in brain activations after a combined sensorimotor and cognitive training for gait rehabilitation. The protocol consisted of the integrated use of a robotic gait orthosis prototype with locomotor imagery tasks. Assessment was conducted on two patients with chronic traumatic brain injury and major gait impairments, using functional magnetic resonance imaging. Physiatric functional scales were used to assess clinical outcomes. Results showed greater activation post-training in the sensorimotor and supplementary motor cortices, as well as enhanced functional connectivity within the motor network. Improvements in balance and, to a lesser extent, in gait outcomes were also found.

    Childhood maltreatment is a serious public health problem and represents a significant challenge to pediatricians. Maltreated children present with a variety of emotional and behavioral problems. Pediatricians should screen for risk factors associated with maltreatment and psychiatric sequelae associated with maltreatment. Because of the complexity of psychiatric sequelae in childhood maltreatment, children who have been maltreated will likely require multidisciplinary treatment in mental health care settings. Therefore, pediatricians need to be knowledgeable about mental health services in their communities and actively assist the family in obtaining services. Although we are gaining a more sophisticated understanding of the impact that maltreatment has on the mental health of children and adolescents, much remains to be done. It is critical for pediatricians to work within their professional organizations and their individual communities to address the systemic issues that create barriers to care for patients who have suffered maltreatment. It is also critical for pediatricians to encourage their professional organizations to establish good working relationships with other organizations in areas where they share interest, need, and commitment. Such collaborative relationships at local, state, and national levels can facilitate governmental policy changes that are needed to protect and care for children and adolescents. Only through such efforts can we bring about lasting changes that will support the health and well-being of children and adolescents. PMID:12846017

    Radiotherapy may result in endocrine abnormalities, osteoporosis, obesity and neurological sequelae in patients treated for cancer. In the hypothalamo-pituitary area, GH deficiency is the most frequent complication. The frequency, delay of appearance and severity of GH deficiency depend most on the dose delivered during cranial irradiation but variables as age at treatment and fractionation schedule may play an important role as well. Other hypothalamo-pituitary dysfunctions are also dose-dependent. Low dose cranial irradiation may induce precocious or early puberty, while high doses are related to gonadotropin deficiency. Endocrine complications due to extracranial irradiation such as gonadal or thyroid abnormalities are described. In spite of normal GH secretion, linear growth may be impaired by bone lesions secondary to craniospinal or total body irradiation. Results on final height have been optimized by better indicators of GH therapy associated with adequate treatment of early or precocious puberty. The purpose of this review is to explore the late endocrine sequelae of radiotherapy. (author)

  1. Radiotherapy for pituitary adenoma: long-term outcome and sequelae

    International Nuclear Information System (INIS)

    Purpose/Objective: To review outcome and treatment sequelae in patients treated with external-beam radiotherapy for pituitary adenomas. Materials and Methods: One hundred forty-one patients with pituitary adenomas received radiotherapy and had 2-year minimum follow-up. One hundred twenty-one patients had newly diagnosed adenomas and 20 patients had recurrent tumors. Newly diagnosed tumors were treated with surgery and radiotherapy (S + RT; n=98) or radiotherapy alone (RT; n=23). Patients with recurrent tumors received salvage treatment with S+RT (n=10) or RT (n=10). The impact of age, sex, presenting symptoms, tumor extent, surgery type, degree of resection, hormonal activity, primary or salvage therapy, and radiotherapy dose on local control and cause-specific survival was analyzed. Effect of therapy on vision, hormonal function, life satisfaction, neurocognitive function, and affective symptoms was examined. A Likert scale survey was used for assessment of life satisfaction, neurocognitive status, and affective symptoms after therapy. Survey results from the RT patients were compared to a control group treated with transsphenoidal surgery alone (S). Survival analysis employed the Kaplan-Meier method. Multivariate analysis used the forward step-wise sequence of chi-squares for the log-rank test. Results: At 10 years, local control for the S+RT group (S + RT) was 95% and not statistically different (p=.58) than for patients in the RT group (90%). Cause-specific survival rates were also similar (p=.88) between the S+RT (97%) and RT (99%) groups. Patients with prolactin- and ACTH-secreting tumors had significantly worse local control, as did patients treated for recurrent tumors. Cause-specific survival was not decreased in any patient group. Multivariate analysis for local control and cause-specific survival revealed only young age to be predictive of worse outcome (p=.0354 and p=.0355 respectively). Visual function was either unaffected or improved in most patients

    Full Text Available Abstract Background Many patients suffer from chronic neck pain following a whiplash injury. A combination of cognitive, behavioural therapy with physiotherapy interventions has been indicated to be effective in the management of patients with chronic whiplash-associated disorders. The objective is to present the design of a randomised controlled trial (RCT aimed at evaluating the effectiveness of a combined individual physical and cognitive behavioural-graded activity program on self-reported general physical function, in addition to neck function, pain, disability and quality of life in patients with chronic neck pain following whiplash injury compared with a matched control group measured at baseline and 4 and 12 months after baseline. Methods/Design The design is a two-centre, RCT-study with a parallel group design. Included are whiplash patients with chronic neck pain for more than 6 months, recruited from physiotherapy clinics and an out-patient hospital department in Denmark. Patients will be randomised to either a pain management (control group or a combined pain management and training (interventiongroup. The control group will receive four educational sessions on pain management, whereas the intervention group will receive the same educational sessions on pain management plus 8 individual training sessions for 4 months, including guidance in specific neck exercises and an aerobic training programme.

    The neuropsychiatric sequelae of chronic Lyme disease remains unclear. This study sought to characterize the psychological status of a group of participants who met criteria for post-Lyme syndrome (PLS). These measures were then used to examine the influence of psychological status on neuropsychological performances. Thirty PLS participants completed a structured psychiatric interview, the Positive and Negative Affect Schedule, the Lyme Symptom Checklist, and a battery of neuropsychological tests. As a group, the PLS participants did not appear to have an elevated incidence of psychiatric disorders, and psychiatric history was not useful for understanding neuropsychological performances or symptom reports. The mood of the PLS participants was characterized by lowered levels of positive affect (PA) and typical levels of negative affect. This combination can be distinguished from depression and is consistent with previous findings of affect patterns in individuals with chronic fatigue syndrome. PA was also linked to both total symptom severity and severity of cognitive complaints, but not to duration of illness, neurological manifestations at initial diagnosis, or treatment history. Relative to published normative data, neuropsychological performances were not in the impaired range on any measure. Neither psychological status nor symptom report were useful for understanding any aspect of cognitive functioning. It is concluded that decreased PA is the most useful marker of psychological functioning in PLS.

    Full Text Available Varicella zoster infection is known to cause neurological involvement. The infection is usually self-limiting and resolves without sequelae. We present a series of three cases with neurological presentations following chicken pox infection. The first case is a case of meningitis, cerebellitis and polyradiculopathy, the second is a florid case of acute infective demyelinating polyradiculoneuropathy (Guillian-Barrι syndrome in a middle-aged female and the third case is a young man in whom we diagnosed acute transverse myelitis. All these cases presented with distinct neurological diagnoses and the etiology was established on the basis of history and serological tests confirmatory for chicken pox. The cases responded differently to treatment and the patients were left with minimum disability.

    Transcranial dopplerography was performed in 125 children with late (1-3 years) neurologic sequelae of acute neuroinfections. Decreased blood flow velocity (BFV) in middle cerebral arteries of (0.61 of the value in control group) was found in patients with movement disorders. Impairment of the intracranial venous outflow together with both acceleration and asymmetry of blood flow in basal veins was prevalent in children with intracranial hypertension and hydrocephaly syndrome. Hyperconstriction of cerebral vessels together with a low BFV (30% of the initial value) was observed during hyperventilation on the side of the lesion in patients with epileptic syndrome. In children with cerebrasthenic syndrome the effect of cavinton treatment depended on the type of changes in cerebral blood flow: positive effect was found in patients with asymmetric decrease of BFV in anterior cerebral arteries.

  6. Cranial radiation in childhood acute lymphocytic leukemia. Neuropsychologic sequelae

    International Nuclear Information System (INIS)

    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

    Beneficial effects on psychological measures in orthopedic inpatient rehabilitation of patients with chronic low back pain (CLBP) and co-exist-ing depressive symptoms have been shown only for multidisciplinary approaches that incorporate psychotherapeutic interventions. Aim of this study was to verify these findings for pain coping outcomes (pain-related psychological disability, pain-related coping). Short-, mid-, and long-term effects of a standard pain management program that was either solely provided or combined with a supplemental cognitive-behavioral depression management were examined in a consecutive sample of n=84. Patients in both groups showed long-term beneficial effects in pain coping measures. Thus, the standard rehabilitation revealed specific and long-term effects on pain coping. However, further evidence suggests that diagnosis-specific psychotherapeutic treatment elements are required to improve psychological symptoms. PMID:24838435

    2016-09-01

    Cognitive-behavioral couple therapy (CBCT) is an approach to assisting couples that has strong empirical support for alleviating relationship distress. This paper provides a review of the empirical status of CBCT along with behavioral couple therapy (BCT), as well as the evidence for recent applications of CBCT principles to couple-based interventions for individual psychopathology and medical conditions. Several meta-analyses and major reviews have confirmed the efficacy of BCT and CBCT across trials in the United States, Europe, and Australia, and there is little evidence to support differential effectiveness of various forms of couple therapy derived from behavioral principles. A much smaller number of effectiveness studies have shown that successful implementation in community settings is possible, although effect sizes tend to be somewhat lower than those evidenced in randomized controlled trials. Adapted for individual problems, cognitive-behavioral couple-based interventions appear to be at least as effective as individual cognitive behavioral therapy (CBT) across a variety of psychological disorders, and often more effective, especially when partners are substantially involved in treatment. In addition, couple-based interventions tend to have the unique added benefit of improving relationship functioning. Findings on couple-based interventions for medical conditions are more varied and more complex to interpret given the greater range of target outcomes (psychological, relational, and medical variables).

    Background:Cognitive impairment is a severe complication caused by obstructive sleep apnea (OSA).The mechanisms of causation are still unclear.The Wnt/β-catenin signaling pathway is involved in cognition,and abnormalities in it are implicated in neurological disorders.Here,we explored the Wnt/β-catenin signaling pathway abnormalities caused by chronic intermittent hypoxia (CIH),the most characteristic pathophysiological component of OSA.Methods:We divided 32 4-week-old male C57/BL mice into four groups of eight each:a CIH + normal saline (NS) group,CIH + LiC1 group,sham CIH + NS group,and a sham CIH + LiC1 group.The spatial learning performance of each group was assessed by using the Morris water maze (MWM).Protein expressions of glycogen synthase kinase-3β (GSK-3β) and β-catenin in the hippocampus were examined using the Western blotting test.EdU labeling and terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling staining methods were used,respectively,to determine the proliferation and apoptosis of neurons in the hippocampal dentate gyrus region.Results:Mice exposed to CIH showed impaired spatial learning performance in the MWM,including increased mean escape latencies to reach the target platform,decreased mean times passing through the target platform and mean duration in the target quadrant.The GSK-3β activity increased,and expression of β-catenin decreased significantly in the hippocampus of the CIH-exposed mice.Besides,CIH significantly increased hippocampal neuronal apoptosis,with an elevated apoptosis index.Meanwhile,LiCl decreased the activity of GSK-3β and increased the expression of β-catenin and partially reversed the spatial memory deficits in MWM and the apoptosis caused by CIH.Conclusions:Wnt/β-catenin signaling pathway abnormalities possibly play an important role in the development of cognitive deficits among mice exposed to CIH and that LiCl might attenuate CIH-induced cognitive impairment via Wnt

    Background: Radiation-induced esophagitis is a frequent acute side effect in curative and palliative radiotherapy of thoracal and cervical tumors. Late reactions are rare but might be severe. Methods: A resarch for reports on prophylactic and supportive therapies of radiation-induced esophagitis was performed (Medline, Cancerlit, and others). Results: Nutrition must be ensured and symptomatic relief of sequelae is important, especially in the case of dysphagia. The latter can be improved by topic or systemic analgetics. If esophageal spasm occurs, calcium antagonists might help. In case of gastro-esophageal reflux proton pump inhibitors should be used. There is no effective prophylactic measure for radiation esophagitis. Late side effects with clinical relevance are rare in conventional radiotherapy. Chronic ulcera, fistula or stenosis may develop. Before any treatment, a tumor infiltration of the esophagus should be excluded by biopsy. This can lead more often to late complications than radiation therapy itself. Nutrition should be ensured by endoscopic dilation, stent-implantation, or endoscopic percutaneous gastrostomy. Local injection of steroids might be used to avoid an early restenosis. Conclusions: An intensive symptomatic therapy of acute esophagitis is reasonable. Effective prophylaxis do not exist. Late radiation induced sequelae is rare. Therefore, a tumor recurrenc e should be excluded in cases of dysphagia. Securing nutrition by PEG, stent, or port is well in the fore. (orig.)

    Objective To analyze the characteristics of Montreal Cognitive Assessment (MoCA) scale and P300 changes in the patients with senile chronic cerebral circulation insufficiency (CCCI) for improving diagnostic accuracy of cognition impairment in the patients with CCCI. Methods Cognitive function in 22 cases of inpatients with senile CCCI and 16 cases of control were evaluated using MoCA.P300 was measured with auditory sense oddball program of myoeletricity-evoked potential apparatus.Results patients in the senile CCCI group had lower score of MoCA as compared with the patients in the control group and the difference was statistically significant (18.23 ±-1.8 vs 22.19-4-5.96, P < 0.05).There was also striking differences between two groups in spatial disorientation and executive function and memory(2.18±0. 66 vs 2.62± 1.15, P < 0.05; 2.64-1-0.66 vs 3.44± 1.15, P < 0.05). The P300 latency in the senile CCCI group was significantly longer than that in the control group(445.45::k37.51) ms vs(336.38± 16.50)ms, P < 0.01. Conclusions senile CCCI patients had cognition impairment and the impairment of spatial disorientation, executive function and memory was very obvious. Delay of P300 latency could reflect cognition impairment of senile CCCI patients. MoCA and P300 were can be used easily as effective methods to evaluate cognitive function of senile CCCI patients.%目的 分析老年性慢性脑供血不足(CCCI)蒙特利尔认知评估量表(MoCA)及P300改变的特点,以期提高对CCCI认知功能受损的诊断水平.方法 使用MoCA对22例住院老年CCCl患者及16例对照组进行认知功能测定.使用肌电-诱发电位仪的oddball程序检测患者及对照组的P300.结果 老年CCCI组MoCA评定总分低于对照组,差异显著(18.23±1.8 vs 22.19±5.96,P<0.05)对各项得分分析显示,主要表现在视空间与执行功能和记忆两项差异显著(2.18±0.66 vs 2.62±1.15,P<0.05;2.64±0.66 vs 3.44±1.15,P<0.05).老年CCCI组P300

    One hundred forty-three patients who received radiation therapy for childhood tumors, and survived to the age of skeletal maturity, were studied by retrospective review of oncology records and roentgenograms. Diagnoses for the patients were the following: Hodgkin's lymphoma (44), Wilms's tumor (30), acute lymphocytic leukemia (26), non-Hodgkin's lymphoma (18), Ewing's sarcoma (nine), rhabdomyosarcoma (six), neuroblastoma (six), and others (four). Age at the follow-up examination averaged 18 years (range, 14-28 years). Average length of follow-up study was 9.9 years (range, two to 18 years). Asymmetry of the chest and ribs was seen in 51 (36%) of these children. Fifty (35%) had scoliosis; 14 had kyphosis. In two children, the scoliosis was treated with a brace, while one developed significant kyphosing scoliosis after laminectomy and had spinal fusion. Twenty-three (16%) patients complained of significant pain at the radiation sites. Twelve of the patients developed leg-length inequality; eight of those were symptomatic. Three patients developed second primary tumors. Currently, the incidence of significant skeletal sequelae is lower and the manifestations are less severe than reported in the years from 1940 to 1970. The reduction in skeletal complications may be attributed to shielding of growth centers, symmetric field selection, decreased total radiation doses, and sequence changes in chemotherapy.

    This pilot, open-protocol study examined whether scalp application of red and near-infrared (NIR) light-emitting diodes (LED) could improve cognition in patients with chronic, mild traumatic brain injury (mTBI). Application of red/NIR light improves mitochondrial function (especially in hypoxic/compromised cells) promoting increased adenosine triphosphate (ATP) important for cellular metabolism. Nitric oxide is released locally, increasing regional cerebral blood flow. LED therapy is noninvasive, painless, and non-thermal (cleared by the United States Food and Drug Administration [FDA], an insignificant risk device). Eleven chronic, mTBI participants (26-62 years of age, 6 males) with nonpenetrating brain injury and persistent cognitive dysfunction were treated for 18 outpatient sessions (Monday, Wednesday, Friday, for 6 weeks), starting at 10 months to 8 years post- mTBI (motor vehicle accident [MVA] or sports-related; and one participant, improvised explosive device [IED] blast injury). Four had a history of multiple concussions. Each LED cluster head (5.35 cm diameter, 500 mW, 22.2 mW/cm(2)) was applied for 10 min to each of 11 scalp placements (13 J/cm(2)). LEDs were placed on the midline from front-to-back hairline; and bilaterally on frontal, parietal, and temporal areas. Neuropsychological testing was performed pre-LED, and at 1 week, and 1 and 2 months after the 18th treatment. A significant linear trend was observed for the effect of LED treatment over time for the Stroop test for Executive Function, Trial 3 inhibition (p=0.004); Stroop, Trial 4 inhibition switching (p=0.003); California Verbal Learning Test (CVLT)-II, Total Trials 1-5 (p=0.003); and CVLT-II, Long Delay Free Recall (p=0.006). Participants reported improved sleep, and fewer post-traumatic stress disorder (PTSD) symptoms, if present. Participants and family reported better ability to perform social, interpersonal, and occupational functions. These open-protocol data suggest that placebo

    The brains of fatal cases of cerebral malaria exhibit capillary occlusion, punctiform hemorrhages, and focal necrosis in subcortical white matter. Some studies have suggested that the brain pathology of survivors is similar to that of fatal cases. The purpose of this study was to investigate the hypothesis that cerebral malaria survivors would exhibit neuropsychological impairment due to the residual cerebral damage sustained from the infection. Vietnam veterans reporting a history of cerebral malaria were compared with a group of veterans with a history of combat-related injuries on standard neuropsychological tasks and on dichotic listening (DL). The cerebral malaria group performed worse on memory tasks and exhibited greater clinical impairments on DL, consistent with presumed disruption of subcortical white matter tracts. PMID:16318473

    This retrospective study aimed at determining the predicted risks of clinical and radiographic complications in primary teeth following traumatic dental injuries, according to injury type, severity and child's age. Data were collected from records of children treated at a Dental Trauma Center in Brazil for nine years. Records of 576 children were included; clinical sequelae were assessed in 774 teeth, and radiographic sequelae, in 566 teeth. A total of 408 teeth (52.7%) had clinical sequelae and 185 teeth (32.7%), radiographic sequelae. The type of injury with the highest number of clinical sequelae was the crown-root fracture (86.4%). Clinical sequelae increased with injury severity (p teeth with enamel fracture, and 26.0% (95%CI 14-40) for teeth with enamel dentin fracture as well as enamel dentin pulp fracture. Risk of periapical radiolucency was higher for teeth with enameldentinpulp fracture (61.1% 95%CI 35-82) and those with subluxation (15.8% 95%CI 10-22). Risk of premature loss was 27.3% (95%CI 13-45) for teeth with extrusive luxation, and 10.2% (95%CI 5-17) for those with intrusive luxation. The assessment of predicted risks of sequelae showed that teeth with hard tissue trauma tended to present color change, periapical radiolucency and premature loss, whereas teeth with supporting tissue trauma showed color change, abnormal position, premature loss and periapical radiolucency as the most common sequelae. Knowledge about the predicted risks of complications may help clinicians establish appropriate treatment plans.

    The authors examined the role of food insecurity in the etiology of children's cognitive and mental health problems. Data from a prospective longitudinal study of 1,116 United Kingdom families with twins (sample constructed in 1999–2000) were used to test associations among household food insecurity; income; maternal personality; household sensitivity to children's needs; and children's cognitive, behavioral, and emotional development. Food-insecure children had lower IQs and higher levels of behavioral and emotional problems relative to their peers. After differences in household income, the personalities of children's mothers, and the sensitivity of household organization to children's needs were accounted for, food-insecure children had moderately higher levels of emotional problems relative to food-secure children (β = 0.22, P = 0.02). Differences in children's cognitive development were accounted for by household income, and differences in their behavioral development were accounted for by their mothers’ personalities and their households’ sensitivity to children's needs. Results suggest that food insecurity was associated with school-aged children's emotional problems but not with their cognitive or behavioral problems after accounting for differences in the home environments in which children were reared. Mothers’ personality and household sensitivity to children's needs may present challenges to improving outcomes of children with food insecurity. PMID:20716700

    Full Text Available The essential oil of Syzygium aromaticum has been widely used in traditional medicine to treat a variety of diseases, including some neurological disorders. This study aims at testing, in vivo, the possible anxiolytic and antidepressant effects, of the Syzygium aromaticum essential oil against chronic manganese chloride (4.79 mg/l intoxication during the gestation and lactation period, in Wistar rat pups. Wistar rat pups were exposed to manganese via their dams’ drinking water from postnatal day (PND 1 to (PND 21. After their weaning, the rats exposed to manganese received injections of essential oil of Syzygium aromaticum (0.1 ml/kg for 18 days. The level of anxiety, depression and locomotor activity were studied. Locomotor activity (open field test, anxiety (elevated plus maze tests, and depression (forced swimming test were evaluated. The results of the present study indicate that Manganese exposure induces, on the one hand, impairments of body (p<0.001 and of brain weight (p<0.05. On the other hand, it increases level of anxiety (p<0.05, depression (p<0.001 and locomotor hyporactivity (p<0.001, when compared to control rats. Administration of essential oil of Syzygium aromaticum leads to a reduction in the level of anxiety (p<0.05, of depression (p<0.001 and corrects locomotor hyporactivity (p<0.05 in rats exposed to manganese beforehand. These results suggest that essential oil of Syzygium aromaticum can employ as a natural, protective agent against neuro-toxicity induced by manganese chloride during the gestation and lactation periods.

    During the past three decades, improvements in the treatment of childhood leukemia have resulted in high cure rates, particularly for acute lymphoblastic leukemia (ALL). Unfortunately, successful therapy has come with a price, as significant morbidity can result from neurological affects which harm the brain and spinal cord. The expectation and hope is that chemotherapy, as a primary means of CNS therapy, will result in acceptable disease control with less CNS morbidity than has been observed with combinations of chemotherapy and radiotherapy over the past several decades. In this review we discuss the poignant, historical aspects of CNS leukemia therapy, outline current methods of systemic and CNS leukemia therapy, and present imaging findings we have encountered in childhood leukemia patients with a variety of acute neurological conditions. A major objective of our research is to understand the neuroimaging correlates of acute and chronic effects of cancer and therapy. Specific features related to CNS leukemia and associated short-term toxicities, both disease- and therapy-related, are emphasized in this review with the specific neuroimaging findings. Specific CNS findings are similarly important when treating acute myelogenous leukemia (AML), and details of leukemic involvement and toxicities are also presented in this entity. Despite contemporary treatment approaches which favor the use of chemotherapy (including intrathecal therapy) over radiotherapy in the treatment of CNS leukemia, children still occasionally experience morbid neurotoxicity. Standard neuroimaging is sufficient to identify a variety of neurotoxic sequelae in children, and often suggest specific etiologies. Specific neuroimaging findings frequently indicate a need to alter antileukemia therapy. It is important to appreciate that intrathecal and high doses of systemic chemotherapy are not innocuous and are associated with acute, specific, recognizable, and often serious neurological

    Full Text Available Abstract Background Early trauma-focused cognitive-behavioural therapy (TFCBT holds promise as a preventive intervention for people at risk of developing chronic post-traumatic stress disorder (PTSD. The aim of this review was to provide an updated evaluation of the effectiveness of early TFCBT on the prevention of PTSD in high risk populations. Methods We performed a systematic literature search in international electronic databases (MEDLINE, EMBASE, PsycINFO, CENTRAL, CINAHL, ISI and PILOTS and included randomised controlled trials comparing TFCBT delivered within 3 months of trauma, to alternative interventions. All included studies were critically appraised using a standardised checklist. Two independent reviewers selected studies for inclusion and assessed study quality. Data extraction was performed by one reviewer and controlled by another. Where appropriate, we entered study results into meta-analyses. Results Seven articles reporting the results of five RCTs were included. All compared TFCBT to supportive counselling (SC. The study population was patients with acute stress disorder (ASD in four trials, and with a PTSD diagnosis disregarding the duration criterion in the fifth trial. The overall relative risk (RR for a PTSD diagnosis was 0.56 (95% CI 0.42 to 0.76, 1.09 (95% CI 0.46 to 2.61 and 0.73 (95% CI 0.51 to 1.04 at 3–6 months, 9 months and 3–4 years post treatment, respectively. A subgroup analysis of the four ASD studies only resulted in RR = 0.36 (95% CI 0.17 to 0.78 for PTSD at 3–6 months. Anxiety and depression scores were generally lower in the TFCBT groups than in the SC groups. Conclusion There is evidence for the effectiveness of TFCBT compared to SC in preventing chronic PTSD in patients with an initial ASD diagnosis. As this evidence originates from one research team replications are necessary to assess generalisability. The evidence about the effectiveness of TFCBT in traumatised populations without an ASD

  14. Chronic kidney disease, 24-h blood pressure and small vessel diseases are independently associated with cognitive impairment in lacunar infarct patients

    International Nuclear Information System (INIS)

    Although the relationships between chronic kidney disease (CKD) and cognitive impairment (CI) have been highlighted, the etiology of CI in CKD remains uncertain. Subjects comprised 224 consecutive patients with symptomatic lacunar infarction who underwent magnetic resonance imaging and ambulatory blood pressure monitoring (ABPM). Diurnal blood pressure (BP) patterns were categorized into three groups: dippers, non-dippers and risers. Lacunar infarcts (LIs), including both symptomatic and silent and diffuse white matter lesions (WMLs), were graded into three grades according to their degree. The results of kidney function were evaluated using estimated glomerular filtration rate (eGFR), categorized into three groups: stage 1, >60; stage 2, 30-60; and stage 3, -1 per 1.73 m2. There were 44 patients with CI. Confluent WMLs, including WML 2 and WML 3, were found in 36 patients (81.8%), and multiple lacunae including LI 2 and LI 3 were found in 30 patients (68.1%) with CI. Age >75 years (odds ratio (OR), 5.5; P-1 per 1.73 m2 (OR, 2.9; P-1 per 1.73 m2 (OR, 23.8; P75 years (OR, 4.1; P-1 per 1.73 m2 (OR, 3.7; P-1 per 1.73 m2 (OR, 8.7; P<0.05) were independently associated with WML grade 3. Extensive small vessel diseases, CKD and non-dipping status were independently associated with CI. CKD appears to mainly contribute to vascular CI, whereas possibilities of overlapping with other mechanisms such as degenerative CI cannot be excluded. Strict night time BP control and renoprotective treatment may be warranted to prevent CI. (author)

    Abstract Background Socioeconomic gradients in health persist despite public health campaigns and improvements in healthcare. The Psychosocial and Biological Determinants of Ill-health (pSoBid) study was designed to uncover novel biomarkers of chronic disease that may help explain pathways between socioeconomic adversity and poorer physical and mental health. Methods We examined links between indicators of early life adversity, possible intermediary phenotypes, and markers of ill health in adult subjects (n = 666) recruited from affluent and deprived areas. Classical and novel risk factors for chronic disease (lung function and atherosclerosis) and for cognitive performance were assessed, and associations sought with early life variables including conditions in the parental home, family size and leg length. Results Associations were observed between father\\'s occupation, childhood home status (owner-occupier; overcrowding) and biomarkers of chronic inflammation and endothelial activation in adults (C reactive protein, interleukin 6, intercellular adhesion molecule; P < 0.0001) but not number of siblings and leg length. Lung function (forced expiratory volume in 1 second) and cognition (Choice Reaction Time, the Stroop test, Auditory Verbal Learning Test) were likewise related to early life conditions (P < 0.001). In multivariate models inclusion of inflammatory variables reduced the impact and independence of early life conditions on lung function and measures of cognitive ability. Including variables of adult socioeconomic status attenuated the early life associations with disease biomarkers. Conclusions Adverse levels of biomarkers of ill health in adults appear to be influenced by father\\'s occupation and childhood home conditions. Chronic inflammation and endothelial activation may in part act as intermediary phenotypes in this complex relationship. Reducing the \\'health divide\\' requires that these life course determinants are taken into account.

    The effects of addictive drugs change with repeated use: many individuals become tolerant of their pleasurable effects but also more sensitive to negative sequelae (e.g., anxiety, paranoia, and drug craving). Understanding the mechanisms underlying such tolerance and sensitization may provide valuable insight into the basis of drug dependency and addiction. We have recently shown that chronic cocaine administration reduces the ability of an acute injection of cocaine to affect impulsivity in rats. However, animals become more impulsive during withdrawal from cocaine self-administration. We have also shown that chronic administration of cocaine increases expression of the transcription factor DeltaFosB in the orbitofrontal cortex (OFC). Mimicking this drug-induced elevation in OFC DeltaFosB through viral-mediated gene transfer mimics these behavioural changes: DeltaFosB over-expression in OFC induces tolerance to the effects of an acute cocaine challenge but sensitizes rats to the cognitive sequelae of withdrawal. Here we report novel data demonstrating that increasing DeltaFosB in the OFC also sensitizes animals to the locomotor-stimulant properties of cocaine. Analysis of nucleus accumbens tissue taken from rats over-expressing DeltaFosB in the OFC and treated chronically with saline or cocaine does not provide support for the hypothesis that increasing OFC DeltaFosB potentiates sensitization via the nucleus accumbens. These data suggest that both tolerance and sensitization to cocaine's many effects, although seemingly opposing processes, can be induced in parallel via the same biological mechanism within the same brain region, and that drug-induced changes in gene expression within the OFC play an important role in multiple aspects of addiction.

    The pathogenesis of cancer anorexia/cachexia is still unclear, partly explaining why its treatment remains disappointing. Anorexia plays a central role but cancer cachexia is more complex than chronic starvation. One of the key differences is the preferential mobilization of fat and the sparing of skeletal muscle in simple starvation compared to an equal mobilization of fat and skeletal muscle in cancer patients. An increase in basal energy expenditure also appears to play a contributory role in many patients. Cytokines, essentially but not exclusively tumor necrosis factor-alpha, play an essential pathogenic role and the syndrome can be compared to a low grade chronic inflammatory state. Parenteral nutrition could facilitate the administration of complete doses of chemotherapy or radiotherapy but no significant survival benefit or decrease in treatment-induced toxicity have been demonstrated in prospective randomized trials. The gut should have the preference for nutritional support. Percutaneous endoscopic gastrostomy is used more and more often in patients with a functionally intact gastrointestinal tract, especially in patients with head and neck cancer. Progestational drugs can to some extent stimulate appetite, food intake, energy level, increase weight and decrease the severity of nausea and vomiting. However, pharmacological treatment of cancer cachexia remains disappointing and more trials with anticytokine drugs, anabolic agents or polyunsaturated fatty acids should be conducted.

    Tuberculosis (TB), caused by Mycobacterium tuberculosis, is an ancient infectious disease that remains a global health problem. Chest radiography is the method commonly employed in assessing the evolution of TB. However, lung damage quantification methods are usually performed on a computerized tomography (CT). This objective quantification is important in the radiological monitoring of the patient by assessing the progression and treatment of TB. However, precise quantification is not feasible by the number of CT examinations necessary due to the high dose subjected to the patient and high cost to the institution. The purpose of this work is to develop a tool to quantify pulmonary sequelae caused by TB through chest X-rays. Aiming the proposed objective, a computational algorithm was developed, creating a three-dimensional representation of the lungs, with regions of dilated sequelae inside. It also made the quantification of pulmonary sequelae of these patients through CT scans performed in upcoming dates, minimizing the differences in disease progression. The measurements from the two methods were compared with results suggest that the effectiveness and applicability of the developed tool, allowing lower doses radiological monitoring of the patient during treatment.

    Left atrial wall dissection is a rare condition; most cases are iatrogenic after mitral valve surgery. A few have been reported as sequelae of blunt chest trauma, acute myocardial infarction, and invasive cardiac procedures. On occasion, infective endocarditis causes left atrial wall dissection. We report a highly unusual case in which a 41-year-old man presented with native mitral valve infective endocarditis that had caused left atrial free-wall dissection. Although our patient died within an hour of presentation, we obtained what we consider to be a definitive diagnosis of a rare sequela, documented by transthoracic and transesophageal echocardiography.

    2010-11-01

    Full Text Available Phencyclidine (PCP induces a behavioural syndrome in rodents that bears remarkable similarities to some of the core symptoms observed in schizophrenic patients, among those cognitive deficits. The successful alleviation of cognitive impairments associated with schizophrenia (CIAS has become a major focus of research efforts as they remain largely untreated. The aim of the present study was to investigate the effects of selected antipsychotic and cognition enhancing drugs, namely haloperidol, risperidone, donepezil, and modafinil in an animal model widely used in preclinical schizophrenia research. To this end, the novel object recognition (NOR task was applied to rats abstinent following sub-chronic treatment with PCP. Rats were administered either PCP (5 mg/kg, i.p. or vehicle twice a day for 7 days, followed by a 7-day washout period, before testing in NOR. Upon testing, vehicle-treated rats successfully discriminated between novel and familiar objects, an effect abolished in rats that had previously been exposed to PCP-treatment. Acute treatment with modafinil (64 mg/kg, p.o. ameliorated the PCP-induced deficit in novel object exploration, whereas haloperidol (0.1 mg/kg, s.c., risperidone (0.2 mg/kg, i.p. and donepezil (3 mg/kg, p.o. were without significant effect. Given the negligible efficacy of haloperidol and risperidone, and the contradictory data with donepezil to treat CIAS in the clinic, together with the promising preliminary pro-cognitive effects of modafinil in certain subsets of schizophrenic patients, the sub-chronic PCP-NOR abstinence paradigm may represent an attractive option for the identification of potential novel treatments for CIAS.

    [Purpose] The present study investigated a wide range of stroke patients living in South Korea using the Korean Community Health Survey raw data to determine the correlation between stroke and physical activity. [Subjects and Methods] This study used raw data from the 2012 Korean Community Health Survey. The total number of participants was 228,921; of the 4,475 stroke patients who had been diagnosed by a medical doctor or an oriental medical doctor, the data for 4,460 patients, excluding 15 whose amount of physical activity was unclear, were used in the analysis. [Results] The amount of physical activity performed by patients who had sequelae was significantly lower than that performed by patients who no longer had sequelae. Similarly, for the type of sequelae, palsy in the arms and legs, facial palsy, communication disability, swallowing or eating disability, and visual disability were associated with lower physical activity. Furthermore, as the number of sequelae increased, patients performed significantly less physical activity. [Conclusion] The findings suggest that when decisions on national policies and budgets are made, methods for increasing the physical activity of patients with a history of stroke should be considered.

Dressing-related trauma is recognized as a clinical and economic burden to patients and health care providers. This study was conducted to garner expert opinion on clinical sequelae and resource use associated with dressing-related trauma in a UK setting.Methods: This was an exploratory study with two phases: qualitative pilot interviews with six wound care specialists to explore dressing-related trauma concepts, sequelae, and resource utilization; and online quantitative research with 30 wound care specialists to validate and quantify the concepts, sequelae, and resource utilization explored in the first phase of the study. Data were collected on mean health care professional time, material costs, pharmaceutical costs, and inpatient management per sequela occurrence until resolution. Data were analyzed to give total costs per sequela and concept occurrence.Results: The results demonstrate that dressing-related trauma is a clinically relevant concept. The main types of dressing-related trauma concepts included skin reactions, adherence to the wound, skin stripping, maceration, drying, and plugging of the wound. These were the foundation for a number of clinical sequelae, including wound enlargement, increased exudate, bleeding, infection, pain, itching/excoriation, edema, dermatitis, inflammation, and anxiety. Mean total costs range from £56 to £175 for the complete onward management of each occurrence of the six main concepts.Conclusion: These results provide insight into the hidden costs of dressing-related trauma in a UK setting.

    2002-09-01

    Lyme disease is currently the most common vector-borne illness in the United States. The disease is multisystemic, and chronic disease, in particular, may be associated with neuropsychological deficits. However, to date, only a few empirical studies exist, which examine the neuropsychological sequelae associated with chronic Lyme disease. A review of the literature shows that the deficits observed in adults with chronic Lyme disease are generally consistent with the deficits that can be seen in processes with primarily frontal systems involvement. These observations are generally consistent with neuroradiologic findings. The clinical presentation in chronic Lyme disease and the nature of the neuropsychological deficits are discussed, as are several central issues in understanding neuropsychological functioning in chronic Lyme disease, such as the impact of chronic illness, response to treatment, and the relationship between neuropsychological performance and depression, fatigue, and neurological indicators of disease.

  8. Navigating Adolescence with a Chronic Health Condition: A Perspective on the Psychological Effects of HAIR-AN Syndrome on Adolescent Girls

    2006-01-01

    Full Text Available HAIR-AN syndrome is a subphenotype of polycystic ovary syndrome and is characterized by acne, obesity, hirsutism, and acanthosis nigricans. It usually manifests in early adolescence, a time of significant developmental change in females across physical, cognitive, social, and emotional domains. We contend that adolescent development for females is difficult, even in the best of circumstances, and having a chronic health condition, like HAIR-AN syndrome, will likely impact the afflicted individual’s development and psychological well-being. While many researchers have discussed the long-term health effects of HAIR-AN and similar disorders, little has been written about the potential psychological sequelae of HAIR-AN on the adolescent girl. We discuss the normal developmental sequence for adolescent girls across early, middle, and late adolescence; discuss common mental health problems that adolescents experience; define HAIR-AN syndrome and its clinical manifestations; and discuss its likely psychological impact on adolescent girls. We also make suggestions for future clinical interventions and research in the area of HAIR-AN syndrome and its psychological sequelae.

  10. Clinical Evaluation of Effects of Chronic Resveratrol Supplementation on Cerebrovascular Function, Cognition, Mood, Physical Function and General Well-Being in Postmenopausal Women—Rationale and Study Design

    Directory of Open Access Journals (Sweden)

    Hamish Michael Evans

    2016-03-01

    Full Text Available Background: This methodological paper presents both a scientific rationale and a methodological approach for investigating the effects of resveratrol supplementation on mood and cognitive performance in postmenopausal women. Postmenopausal women have an increased risk of cognitive decline and dementia, which may be at least partly due to loss of beneficial effects of estrogen on the cerebrovasculature. We hypothesise that resveratrol, a phytoestrogen, may counteract this risk by enhancing cerebrovascular function and improving regional blood flow in response to cognitive demands. A clinical trial was designed to test this hypothesis. Method: Healthy postmenopausal women were recruited to participate in a randomised, double-blind, placebo-controlled (parallel comparison dietary intervention trial to evaluate the effects of resveratrol supplementation (75 mg twice daily on cognition, cerebrovascular responsiveness to cognitive tasks and overall well-being. They performed the following tests at baseline and after 14 weeks of supplementation: Rey Auditory Verbal Learning Test, Cambridge Semantic Memory Battery, the Double Span and the Trail Making Task. Cerebrovascular function was assessed simultaneously by monitoring blood flow velocity in the middle cerebral arteries using transcranial Doppler ultrasound. Conclusion: This trial provides a model approach to demonstrate that, by optimising circulatory function in the brain, resveratrol and other vasoactive nutrients may enhance mood and cognition and ameliorate the risk of developing dementia in postmenopausal women and other at-risk populations.

    Age-related cognitive impairment undergoes a continuous progression:pre-mild cognitive impairment(preMCI),mild cognitive impairment(MCI)and Alzheimer’s disease(AD). So far,chronic dehydration is regarded as a common symptom for the patients with age-related cognitive impairment,in particular of those with AD. Monitored with an infrared-CCD camera,a marked decrease in the drinking frequency(P65 years old)and in the hippocampus of Alzheimer’s patients. Regularly drinking water relieves not only chronic dehydration for aging people,but also significantly decreases the concentration of endogenous formaldehyde, which may offer protection of central nervous system. Therefore,building the habit to regularly drink water should be emphasized at the early stage to relieve chronic dehydration and scavenge cytotoxic metabolic products including formaldehyde for aging people,which might be beneficial to mitigate age-related cognitive impairment at its early stage.%老年认知损伤被认为是一个连续发展的病理生理学过程,包括轻度认知损伤前期(pre-mild cognitive impairment,pre-MCI)、轻度认知损伤(mild cognitive impairment,MCI)、阿尔茨海默病(Alzheimer’s disease, AD)三个阶段,慢性脱水是老年性痴呆患者共同具有的一种特征。红外线摄像监控C57 BL/6小鼠饮水频率和饮水量的结果显示,老龄鼠的饮水频率和饮水量均较年轻对照组显著减少(P65岁)而逐渐升高,且AD病人脑内甲醛含量也显著升高。研究表明,甲醛代谢失调所造成的中枢神经系统慢性损伤被认为是老年认知损伤的原因之一,合理饮水不但可以改善老龄化人群的慢性脱水状态,同时能够明显降低体内的甲醛浓度,防止甲醛过量对中枢神经系统的危害,因此,合理饮水习惯的建立,被认为是减缓中老年人慢性脱水和体内细胞毒性代谢产物累积的方法之一,也可能在某种程度上,起

    Cognitive and affective impairments are important non-motor features of ischemic stroke (IS) related to white-matter hyperintensity, including periventricular hyperintensity (PVH). To confirm the usefulness of a novel computerized touch panel-type screening test, we investigated cognitive and affective functioning among 142 IS patients and 105 age-and gender-matched normal control subjects. Assessment using the mini-mental state examination, Hasegawa Dementia Scale-Revised, and frontal assessment battery revealed reduced cognitive function in IS patients, with the most severe reduction exhibited by cardiogenic embolism patients, followed by lacunar infarction patients, and atherothrombotic infarction patients. Our novel touch panel screening test revealed a similar pattern of results. In addition, PVH grading, classified using Fazekas' magnetic resonance imaging method, was also correlated with cognitive decline and touch panel screening test performance. In contrast, affective function, assessed with the 15-item Geriatric Depression Scale, vitality index, and apathy scale, was not significantly decreased in IS, and did not correlate with touch panel screening test results or PVH, although the number of microbleeds was correlated with apathy scale results. The present findings revealed that IS and PVH grading were significantly correlated with decline in general cognitive status (mini-mental state examination and Hasegawa Dementia Scale-Revised) and frontal lobe function (frontal assessment battery). Performance on all touch panel screening tests was correlated with IS and PVH grading, but was largely independent of depression or apathy. Touch panel screening tests were easily understood and performed by almost all patients with mild cognitive and motor dysfunction, due to visually clear images and simple methods not involving detailed manual-handling tasks such as writing. Touch panel screening tests may provide a useful tool for the early screening of cognitive

    Full Text Available Over the past few decades, chronic obstructive lung disease (COPD has been considered a disease of the lungs, often caused by smoking. Nowadays, COPD is regarded as a systemic disease. Both physical effects and effects on brains, including impaired psychological and cognitive functioning, have been demonstrated. Patients with COPD may have cognitive impairment, either globally or in single cognitive domains, such as information processing, attention and concentration, memory, executive functioning, and self-control. Possible causes are hypoxemia, hypercapnia, exacerbations, and decreased physical activity. Cognitive impairment in these patients may be related to structural brain abnormalities, such as gray-matter pathologic changes and the loss of white matter integrity which can be induced by smoking. Cognitive impairment can have a negative impact on health and daily life and may be associated with widespread consequences for disease management programs. It is important to assess cognitive functioning in patients with COPD in order to optimize patient-oriented treatment and to reduce personal discomfort, hospital admissions, and mortality. This paper will summarize the current knowledge about cognitive impairment as extrapulmonary feature of COPD. Hereby, the impact of smoking on cognitive functioning and the impact of cognitive impairment on smoking behaviour will be examined.

    Braun-Falco, O; Schultze, U; Meinhof, W; Goldschmidt, H

    1975-10-29

    The paper presents statistical data on the therapeutic effects and radiation sequelae following Chaoul contact therapy of 818 cutaneous hemangiomas treated between 1938 and 1952. 73.3% of all irradiated hemangiomas showed initial improvement but complete involution with an excellent cosmetic result was observed in only 50% of lesions 5 years after treatment. During the same period of time, more than one-third of all patients developed mild to moderate cutaneous radiation sequelae (hyper- or hypopigmentation and telangiectases, rarely atrophy). The high incidence of late radiation effects is probably relation to the high total doses administered in this series of patients, the very short intervals between treatments and the age of the patients. Other radiation radiation hazards are also discussed. Since large studies have proven conclusively that spontaneous involution occurs in 95% of hemangiomas after several years, indications for radiotherapy of hemangiomas are extremely limited.

    Electrical impedance is one of the most frequently used parameters for characterizing material properties. The resistive and capacitive characteristics of tissue may be revealed by electrical impedance spectroscopy (EIS) as electrical biopsy. This technique could be used to monitor the sequelae after irradiation. In this study, rat intestinal tissues after irradiation were assessed by EIS system based on commercially available integrated circuits. The EIS results were fitted to a resistor-capacitor circuit model to determine the electrical properties of the tissue. The variations in the electrical characteristics of the tissue were compared to radiation injury score (RIS) by morphological and histological findings. The electrical properties, based on receiver operation curve (ROC) analysis, strongly reflected the histological changes with excellent diagnosis performance. The results of this study suggest that electrical biopsy reflects histological changes after irradiation. This approach may significantly augment the evaluation of tissue after irradiation. It could provide rapid results for decision making in monitoring radiation sequelae prospectively.

    Full Text Available Abstract Introduction The outcome of cerebral ischemic stroke associated with cannabis use is usually favorable. Here we report the first case of cannabis-related stroke followed by neuropsychiatric sequelae. Case presentation A 24-year-old Caucasian man was discovered in a deeply comatose non-reactive state after cannabis use. A magnetic resonance imaging scan of his brain showed bilateral multiple ischemic infarcts. The patient remained deeply comatose for four days, after which time he developed other behavioral impairments and recurrent seizures. Conclusion Stroke related to cannabis use can be followed by severe neuropsychiatric sequelae. Concomitant alcohol intoxication is essential neither to the occurrence of this neurologic event nor to its severity.

  4. Late sequelae and cosmetic outcome after radiotherapy in breast conserving therapy

    International Nuclear Information System (INIS)

    Radiotherapy after breast-conserving therapy for early breast cancer is reported to adversely affect the cosmetic outcome. The incidence of radiation-induced fibro-atrophy is around 10% at 5 years. A better knowledge of its pathophysiology has revealed the essential role of activated fibroblasts and reactive oxygen species, mediated by TGF beta 1, allowing the development of antioxidant in the management of the established radiation-induced fibro-atrophy. Cosmetic sequelae are evaluated with standardized scales, such as the LENT-SOMA and must be monitored during at least 5 years. The main factors determining the occurrence of sequelae are a large breast volume, dose heterogeneity and the use of tumour bed boost after whole-breast radiation therapy. Intensity modulated radiotherapy and partial breast irradiation position themselves as a good alternatives to reduce the incidence of late skin side effects. The use of predictive tests of intrinsic radiosensitivity might fit into the therapeutic strategy. (authors)

    Full Text Available Abstract Background Bacterial meningitis (BM is a severe infection responsible for high mortality and disabling sequelae. Early identification of patients at high risk of these outcomes is necessary to prevent their occurrence by adequate treatment as much as possible. For this reason, several prognostic models have been developed. The objective of this study is to summarize the evidence regarding prognostic factors predicting death or sequelae due to BM in children 0-18 years of age. Methods A search in MEDLINE and EMBASE was conducted to identify prognostic studies on risk factors for mortality and sequelae after BM in children. Selection of abstracts, full-text articles and assessment of methodological quality using the QUIPS checklist was performed by two reviewers independently. Data on prognostic factors per outcome were summarized. Results Of the 31 studies identified, 15 were of moderate to high quality. Due to substantial heterogeneity in study characteristics and evaluated prognostic factors, no quantitative analysis was performed. Prognostic factors found to be statistically significant in more than one study of moderate or high quality are: complaints >48 hours before admission, coma/impaired consciousness, (prolonged duration of seizures, (prolonged fever, shock, peripheral circulatory failure, respiratory distress, absence of petechiae, causative pathogen Streptococcus pneumoniae, young age, male gender, several cerebrospinal fluid (CSF parameters and white blood cell (WBC count. Conclusions Although several important prognostic factors for the prediction of mortality or sequelae after BM were identified, the inability to perform a pooled analysis makes the exact (independent predictive value of these factors uncertain. This emphasizes the need for additional well-conducted prognostic studies.

    Full Text Available Abstract Objective Incomplete recovery from facial palsy has a long-term impact on the quality of life, and medical options for the sequelae of Bell's palsy are limited. Invasive treatments and physiotherapy have been employed to relieve symptoms, but there is limited clinical evidence for their effectiveness. Acupuncture is widely used on Bell's palsy patients in East Asia, but there is insufficient evidence for its effectiveness on Bell's palsy sequelae. The objective is to evaluate the efficacy and safety of acupuncture in patients with sequelae of Bell's palsy. Method/Design This study consists of a randomized controlled trial with two parallel arms: an acupuncture group and a waitlist group. The acupuncture group will receive acupuncture treatment three times per week for a total of 24 sessions over 8 weeks. Participants in the waitlist group will not receive any acupuncture treatments during this 8 week period, but they will participate in the evaluations of symptoms at the start of the study, at 5 weeks and at 8 weeks after randomization, at which point the same treatment as the acupuncture group will be provided. The primary outcome will be analyzed by the change in the Facial Disability Index (FDI from baseline to week eight. The secondary outcome measures will include FDI from baseline to week five, House-Brackmann Grade, lip mobility, and stiffness scales.

  9. Tool for objective quantification of pulmonary sequelae in monitoring of patients with tuberculosis

    International Nuclear Information System (INIS)

    Tuberculosis (TB), caused by Mycobacterium tuberculosis, is an ancient infectious disease that remains a global health problem. Chest radiography is the method commonly employed in assessing the evolution of TB. However, lung damage quantification methods are usually performed on a computerized tomography (CT). This objective quantification is important in the radiological monitoring of the patient by assessing the progression and treatment of TB. However, precise quantification is not feasible by the number of CT examinations necessary due to the high dose subjected to the patient and high cost to the institution. The purpose of this work is to develop a tool to quantify pulmonary sequelae caused by TB through chest X-rays. Aiming the proposed objective, a computational algorithm was developed, creating a three-dimensional representation of the lungs, with regions of dilated sequelae inside. It also made the quantification of pulmonary sequelae of these patients through CT scans performed in upcoming dates, minimizing the differences in disease progression. The measurements from the two methods were compared with results suggest that the effectiveness and applicability of the developed tool, allowing lower doses radiological monitoring of the patient during treatment

    Full Text Available TEMA: cirurgia, radioterapia e quimioterapia são as modalidades terapêuticas usadas no tratamento de câncer bucal. Podem ser usadas isoladas ou conjuntamente. Radiação ionizante causa lesões nos tecidos normais localizados no campo de radiação. Isto se torna particularmente evidente nas regiões de cabeça, uma área complexa composta de várias estruturas diferentes que respondem diferentemente à radiação. As seqüelas orais resultantes podem causar problemas substanciais durante e depois da terapia de radiação e são os maiores fatores de determinação na qualidade de vida dos pacientes. Dentre as complicações da radioterapia estão a xerostomia, osteorradionecrose, mucosite e candidose. OBJETIVO: apresentar aos profissionais de saúde uma reflexão sobre as questões pertinentes às sequelas bucais da radioterapia de cabeça e pescoço. CONCLUSÃO: o acompanhamento odontológico sistemático pode minimizar os efeitos da radiação sobre os tecidos da cavidade bucal.BACKGROUND: surgery, radiotherapy and chemotherapy are therapeutic modalities used in the treatment of oral cancer. They can be used separately or in combination. Ionizing irradiation causes damage to normal tissues located at the radiation field. This becomes particularly evident in the head and neck region, a complex area composed of several dissimilar structures that respond differently to radiation. The resulting oral sequelae may cause substantial problems during and after radiation therapy and are major factors in determining the patient's quality of life. Xerostomia, osteoradionecrosis, mucositis and candidosis are some of radiotherapy's complications. PURPOSE: introduce health professionals to reflect on issues relevant to oral sequelae of head and neck radiotherapy. CONCLUSION: regular dental follow-up may reduce the effects of radiation in the tissues of the oral cavity.

    From psychosomatic view point, the psychological or social stresses and depressive or anxiety disorders are very important factors in the course and the maintenance for migraine patients. These factors are very complex, and often lead the migraine becoming chronic. In the psychosomatic approach, not only the physical assessment for chronic migraine but also the assessments for stress and mental states are done. As the psychosomatic therapies for chronic migraine, autogenic training, biofeedback therapy and cognitive therapy are effective. PMID:22277516

    Horrigan, Patrick; Braman, Jonathan P; Harrison, Alicia

    2016-01-01

    Fractures and dislocations of the elbow can result in adverse outcomes. The elbow is a unique joint that allows for great mobility but is predisposed to instability, either simple or complex, in traumatic settings. Even simple elbow instability, in which no fracture is present, may be associated with tremendous soft-tissue injury. Surgical treatment is often required for complex instability in which various fractures are present. The treatment goals for fixation of elbow fractures and dislocations include stable fracture fixation, a stable concentrically reduced joint, and early range of motion. Continued pain, stiffness, and instability as well as heterotopic ossification are common sequelae of elbow fractures and dislocations. PMID:27049181

    2016-01-01

    Background Data on maternal deaths occurring after the 42 days postpartum reference time is scarce; the objective of this analysis is to explore the trend and magnitude of late maternal deaths and deaths from sequelae of obstetric causes in the Americas between 1999 and 2013, and to recommend including these deaths in the monitoring of the Sustainable Development Goals (SDGs). Methods Exploratory data analysis enabled analyzing the magnitude and trend of late maternal deaths and deaths from sequelae of obstetric causes for seven countries of the Americas: Argentina, Brazil, Canada, Colombia, Cuba, Mexico and the United States. A Poisson regression model was developed to compare trends of late maternal deaths and deaths from sequelae of obstetric causes between two periods of time: 1999 to 2005 and 2006 to 2013; and to estimate the relative increase of these deaths in the two periods of time. Findings The proportion of late maternal deaths and deaths from sequelae of obstetric causes ranged between 2.40% (CI 0.85% – 5.48%) and 18.68% (CI 17.06% – 20.47%) in the seven countries. The ratio of late maternal deaths and deaths from sequelae of obstetric causes per 100,000 live births has increased by two times in the region of the Americas in the period 2006-2013 compared to the period 1999-2005. The regional relative increase of late maternal death was 2.46 (p<0.0001) times higher in the second period compared to the first. Interpretation Ascertainment of late maternal deaths and deaths from sequelae of obstetric causes has improved in the Americas since the early 2000’s due to improvements in the quality of information and the obstetric transition. Late and obstetric sequelae maternal deaths should be included in the monitoring of the SDGs as well as in the revision of the International Classification of Diseases’ 11th version (ICD-11).

    2014-08-01

    Health care organizations, both large and small, frequently undergo processes of change. In fact, if health care organizations are to improve over time, they must change; this includes pain services. The purpose of the present study was to examine a process of change in treatment model within a specialty interdisciplinary pain service in the UK. This change entailed a switch from traditional cognitive-behavioural therapy to a form of cognitive-behavioural therapy called acceptance and commitment therapy. An anonymous online survey, including qualitative and quantitative components, was carried out approximately 15 months after the initial introduction of the new treatment model and methods. Fourteen out of 16 current clinical staff responded to the survey. Three themes emerged in qualitative analyses: positive engagement in change; uncertainty and discomfort; and group cohesion versus discord. Quantitative results from closed questions showed a pattern of uncertainty about the superiority of one model over the other, combined with more positive views on progress reflected, and the experience of personal benefits, from adopting the new model. The psychological flexibility model, the model behind acceptance and commitment therapy, may clarify both processes in patient behaviour and processes of staff experience and skilful treatment delivery. This integration of processes on both sides of treatment delivery may be a strength of acceptance and commitment therapy.

  10. Stress and Cognition: A Cognitive Psychological Perspective

    Science.gov (United States)

    Bourne, Lyle E., Jr.; Yaroush, Rita A.

    2003-01-01

    Research in cognitive psychology has made a significant contribution to our understanding of how acute and chronic stress affect performance. It has done so by identifying some of the factors that contribute to operator error and by suggesting how operators might be trained to respond more effectively in a variety of circumstances. The major purpose of this paper was to review the literature of cognitive psychology as it relates to these questions and issues. Based on the existence of earlier reviews (e.g., Hamilton, & Warburton, 1979; Hockey, 1983) the following investigation was limited to the last 15 years (1988-2002) and restricted to a review of the primary peer-reviewed literature. The results of this examination revealed that while cognitive psychology has contributed in a substantive way to our understanding of stress impact on various cognitive processes, it has also left many questions unanswered. Concerns about how we define and use the term stress and the gaps that remain in our knowledge about the specific effects of stressors on cognitive processes are discussed in the text.

    International Nuclear Information System (INIS)

    8 patients of delayed CO sequelae were evaluated using Brain CT and 99mTc-HMPAO SPECT. The results were as follows; 1) CT findings of delayed CO sequelae were bilateral low density lesion in globus pallidus (1 pt.), diffuse low density in white matter with bilateral low density in white matter (1 pt.), diffuse low density in white matter with bilateral low density in globus pallidus (1 pt.), diffuse low density in white matter with cortical atrophy (1 pt.), bilateral low density in globus pallidus and diffuse low density in white matter with cortical atrophy (1 pt.) and normal in 3 pts. 2) 99mTc-HMPAO Brain SPECT findings of delayed CO sequelae were decreased regiona1 cerebral blood flow (rCBF) in frontal (1 among 8 pts.), frontal and basal ganglia (3 among 8 pts.), and diffuse patch decreased rCBF pattern (4 among 8 pts.) 3) 99mTc-HMPAO Brain SPECT study was well correlated with neurologic symptoms and signs in delayed CO sequelae. Our results may suggest that reduced cerebral blood flow contributes to the development of delayed CO sequelae.

    Full Text Available Objective. To investigate the factors affecting intraoperative hemorrhage and postoperative sequelae after orthognathic surgery. Materials and Methods. Eighty patients with mandibular prognathism underwent surgical mandibular setback with intraoral vertical ramus osteotomy (IVRO. The correlation between the blood loss volume and postoperative VAS with the gender, age, and operating time was assessed using the t-test and Spearman rank correlation coefficient. The correlation between the magnitude of mandibular setback with the presence of TMJ clicking symptoms and lip sensation was also assessed. Results. The mean operating time and blood loss volume for men and women were 249.52 min and 229.39 min, and 104.03 mL and 86.12 mL, respectively. The mean VAS in men and women was 3.21 and 2.93, and 1.79 and 1.32 on the first and second postoperative days. There is no gender difference in the operating time, blood loss, VAS, TMJ symptoms, and lip numbness. The magnitude of mandibular setback was not correlated with immediate and long-term postoperative lip numbness. Conclusion. There are no gender differences in the intraoperative hemorrhage and postoperative sequelae (pain, lip numbness, and TMJ symptoms. In addition, neither symptom was significantly correlated with the amount of mandibular setback.

    Leprosy sequelae patients surmount the inconvenience by the handicap. When people with the handicap are able to do the same act as healthy people, we may not pay attention to the originality and creativity for it. Therefore, we are not able to notice some risks which are hidden. We turned our attention to the denture in the oral region. The methods of putting in and taking out the denture of leprosy sequelae patients are characteristic. Even a partial denture, there are many patients who take out their denture using only their tongue, without touching a clasp with a finger. And they put in the denture by biting. But we had never not announced the details of their methods. So, we investigated how to handle their denture in National Sanatorium Nagashima Aiseien. We explain their methods and show the results. On the other hand, there are a lot of cases of the denture breakage in National Sanatorium Nagashima Aiseien. We think most of these matters occur due to their handicaps. We researched on the cases with dentures broken. In addition, we also describe our countermeasure. PMID:27008825

  16. Animal Models of Virus-Induced Neurobehavioral Sequelae: Recent Advances, Methodological Issues, and Future Prospects

    2010-01-01

    Full Text Available Converging lines of clinical and epidemiological evidence suggest that viral infections in early developmental stages may be a causal factor in neuropsychiatric disorders such as schizophrenia, bipolar disorder, and autism-spectrum disorders. This etiological link, however, remains controversial in view of the lack of consistent and reproducible associations between viruses and mental illness. Animal models of virus-induced neurobehavioral disturbances afford powerful tools to test etiological hypotheses and explore pathophysiological mechanisms. Prenatal or neonatal inoculations of neurotropic agents (such as herpes-, influenza-, and retroviruses in rodents result in a broad spectrum of long-term alterations reminiscent of psychiatric abnormalities. Nevertheless, the complexity of these sequelae often poses methodological and interpretational challenges and thwarts their characterization. The recent conceptual advancements in psychiatric nosology and behavioral science may help determine new heuristic criteria to enhance the translational value of these models. A particularly critical issue is the identification of intermediate phenotypes, defined as quantifiable factors representing single neurochemical, neuropsychological, or neuroanatomical aspects of a diagnostic category. In this paper, we examine how the employment of these novel concepts may lead to new methodological refinements in the study of virus-induced neurobehavioral sequelae through animal models.

    A stroke and aging process can modify the postural control. We aimed to compare the postural control of health elderly individuals to that of individuals with stroke sequelae. This cross-sectional transversal study was made with individuals capable of walking without any assistance and that were considered clinically stable. The study had 18 individuals in the group with stroke sequelae (SG) and 34 in the healthy elderly control group (CG). The participants were evaluated for the timed up and go test (TUG) and force platform. The SG showed the worst results in relation to the time of execution of the TUG and the force platform evaluation. The displacement of center of pressure was worse for both groups in the eyes-closed situation, especially in the anteroposterior direction for the CG. The GS showed worse results in the static and dynamic postural control. The healthy elderly showed more dependence on sight to maintain their static balance and there was no difference in the balance tests in relation to the side affected by the stroke.

    Grounded cognition rejects traditional views that cognition is computation on amodal symbols in a modular system, independent of the brain's modal systems for perception, action, and introspection. Instead, grounded cognition proposes that modal simulations, bodily states, and situated action underlie cognition. Accumulating behavioral and neural evidence supporting this view is reviewed from research on perception, memory, knowledge, language, thought, social cognition, and development. Theories of grounded cognition are also reviewed, as are origins of the area and common misperceptions of it. Theoretical, empirical, and methodological issues are raised whose future treatment is likely to affect the growth and impact of grounded cognition.

    The purpose of this study was to compare cognitive-processing therapy (CPT) with prolonged exposure and a minimal attention condition (MA) for the treatment of posttraumatic stress disorder (PTSD) and depression. One hundred seventy-one female rape victims were randomized into 1 of the 3 conditions, and 121 completed treatment. Participants were assessed with the Clinician-Administered PTSD Scale, the PTSD Symptom Scale, the Structured Clinical Interview for DSM-IV, the Beck Depression Inventory, and the Trauma-Related Guilt Inventory. Independent assessments were made at pretreatment, posttreatment, and 3 and 9 months posttreatment. Analyses indicated that both treatments were highly efficacious and superior to MA. The 2 therapies had similar results except that CPT produced better scores on 2 of 4 guilt subscales. PMID:12182270

    Full Text Available The present study examined the effects of squid phosphatidylserine (Squid-PS on the learning and memory function and the neural activity in rats with TMT-induced memory deficits. The rats were administered saline or squid derived Squid-PS (Squid-PS 50 mg kg−1, p.o. daily for 21 days. The cognitive improving efficacy of Squid-PS on the amnesic rats, which was induced by TMT, was investigated by assessing the passive avoidance task and by performing choline acetyltransferase (ChAT and acetylcholinesterase (AchE immunohistochemistry. 18F-Fluorodeoxyglucose and performed a positron emission tomography (PET scan was also performed. In the passive avoidance test, the control group which were injected with TMT showed a markedly lower latency time than the non-treated normal group (P<0.05. However, treatment of Squid-PS significantly recovered the impairment of memory compared to the control group (P<0.05. Consistent with the behavioral data, Squid-PS significantly alleviated the loss of ChAT immunoreactive neurons in the hippocampal CA3 compared to that of the control group (P<0.01. Also, Squid-PS significantly increased the AchE positive neurons in the hippocampal CA1 and CA3. In the PET analysis, Squid-PS treatment increased the glucose uptake more than twofold in the frontal lobe and the hippocampus (P<0.05, resp.. These results suggest that Squid-PS may be useful for improving the cognitive function via regulation of cholinergic enzyme activity and neural activity.

    INTRODUCTION. Patients with chronic migraine often report lower cognitive performance, which affects their quality of life. AIMS. To analyse whether the mnemonic capacity of patients with chronic migraine is altered or not. SUBJECTS AND METHODS. A cross-sectional study was conducted in patients with chronic migraine evaluated consecutively in our unit, and paired by age (18-60 years) and gender with a control group consisting of cognitively healthy volunteers. The following cognitive instruments were administered: Folstein Minimental State Examination (MMSE), Memory Alteration Test (M@T), Montreal Cognitive Assessment (MoCA) and working memory. RESULTS. A total of 30 patients with chronic migraine were included (mean age: 49.33 ± 10.05 years) paired with a control group of 30 healthy volunteers (mean age: 44.83 ± 10.91 years). The mean elapsed time since onset of the patients with chronic migraine was 4.47 ± 2.74 years. On performing a comparative analysis between the two groups, significant differences were found with overall lower scores in the group of patients with chronic migraine in the MoCA (24.16 versus 29), M@T (43.76 versus 48.8) and working memory tests (17.5 versus 24.26). Performance in the MMSE was similar in both groups. CONCLUSIONS. Patients with chronic migraine can have lower cognitive performance regardless of distracting elements, such as pharmacological factors or psychiatric comorbidity, since chronic migraine can be understood as yet another element within the spectrum of chronic pain.

    Objective: Chronic occupational solvent exposure is associated with long-term cognitive deficits. Cognitive reserve may protect solvent-exposed workers from cognitive impairment. We tested whether the association between chronic solvent exposure and cognition varied by educational attainment, a proxy for cognitive reserve. Methods: Data were drawn from a prospective cohort of French national gas and electricity (GAZEL) employees (n = 4,134). Lifetime exposure to 4 solvent types (chlorinated solvents, petroleum solvents, benzene, and nonbenzene aromatic solvents) was assessed using a validated job-exposure matrix. Education was dichotomized at less than secondary school or below. Cognitive impairment was defined as scoring below the 25th percentile on the Digit Symbol Substitution Test at mean age 59 (SD 2.8; 88% of participants were retired at testing). Log-binomial regression was used to model risk ratios (RRs) for poor cognition as predicted by solvent exposure, stratified by education and adjusted for sociodemographic and behavioral factors. Results: Solvent exposure rates were higher among less-educated patients. Within this group, there was a dose-response relationship between lifetime exposure to each solvent type and RR for poor cognition (e.g., for high exposure to benzene, RR = 1.24, 95% confidence interval 1.09–1.41), with significant linear trends (p < 0.05) in 3 out of 4 solvent types. Recency of solvent exposure also predicted worse cognition among less-educated patients. Among those with secondary education or higher, there was no significant or near-significant relationship between any quantification of solvent exposure and cognition. Conclusions: Solvent exposure is associated with poor cognition only among less-educated individuals. Higher cognitive reserve in the more-educated group may explain this finding. PMID:22641403

    Ionizing radiation is an important treatment modality for a variety of malignant conditions. However, development of radiation-induced skin changes is a significant adverse effect of radiation therapy (RT). Cutaneous repercussions of RT vary considerably in severity, course, and prognosis. When they do occur, cutaneous changes to RT are commonly graded as acute, consequential-late, or chronic. Acute reactions can have severe sequelae that impact quality of life as well as cancer treatment. Th...

    Full Text Available Introduction. The prevalence of chronic diseases in adolescence is constantly increasing, especially in the last two decades. Adolescence is a period of important changes: body growth and development, sexual development, development of cognitive abilities, change in family relations and between peers, formation of personal identity and personal system of values, making decisions on future occupation etc. Chronic diseases in adolescence. Chronic disorders affect all development issues and represent an additional burden for adolescents. The interaction between chronic disorders and various development issues is complex and two-way: the disease may affect development, and development may affect the disease. Developmental, psychosocial and family factors are of great importance in the treatment of adolescents with chronic disorders. Chronic disorders affect all aspects of adolescent life, including relations with peers, school, nutrition, learning, traveling, entertainment, choice of occupation, plans for the future. Physicians should keep in mind that chronic diseases and their treatment represent only one aspect of person's life. Adolescents with chronic diseases have other needs as well, personal priorities, social roles and they expect these needs to be recognized and respected. Adolescent health care should be adjusted to the life style of adolescents.

  5. Frontal Lobe Contusion in Mice Chronically Impairs Prefrontal-Dependent Behavior.

    Directory of Open Access Journals (Sweden)

    Austin Chou

    Full Text Available Traumatic brain injury (TBI is a major cause of chronic disability in the world. Moderate to severe TBI often results in damage to the frontal lobe region and leads to cognitive, emotional, and social behavioral sequelae that negatively affect quality of life. More specifically, TBI patients often develop persistent deficits in social behavior, anxiety, and executive functions such as attention, mental flexibility, and task switching. These deficits are intrinsically associated with prefrontal cortex (PFC functionality. Currently, there is a lack of analogous, behaviorally characterized TBI models for investigating frontal lobe injuries despite the prevalence of focal contusions to the frontal lobe in TBI patients. We used the controlled cortical impact (CCI model in mice to generate a frontal lobe contusion and studied behavioral changes associated with PFC function. We found that unilateral frontal lobe contusion in mice produced long-term impairments to social recognition and reversal learning while having only a minor effect on anxiety and completely sparing rule shifting and hippocampal-dependent behavior.

    Priapism is a common complication of sickle cell anemia. We report a little known sequela of priapism: painless megalophallus, with significant penile enlargement. The patient had had an intense episode of priapism 9 years previously and his penis remained enlarged. Blood oxygen level-dependent magnetic resonance imaging revealed enlarged, hypoxic corpora cavernosa. Megalophallus probably resulted from permanent loss of elasticity of the tunica albuginea due to severe engorgement during the episode of priapism. This sequela needs to be recognized by physicians because no intervention is necessary and sexual function seems to remain intact. PMID:10962334

    This small clinical trial utilized a novel rehabilitation strategy, rapid-resisted elliptical training, in an effort to increase motor, and thereby cognitive, processing speed in ambulatory individuals with traumatic brain injury (TBI). As an initial step, multimodal functional abilities were quantified and compared in 12 ambulatory adults with and 12 without TBI. After the baseline assessment, the group with TBI participated in an intensive 8-week daily exercise program using an elliptical trainer and was reassessed after completion and at an 8-week follow-up. The focus of training was on achieving a fast movement speed, and once the target was reached, resistance to motion was increased in small increments to increase intensity of muscle activation. Primary outcomes were: High-Level Mobility Assessment Tool (HiMAT), instrumented balance tests, dual-task (DT) performance and neurobehavioral questionnaires. The group with TBI had poorer movement excursion during balance tests and poorer dual-task (DT) performance. After training, balance reaction times improved and were correlated with gains in the HiMAT and DT. Sleep quality also improved and was correlated with improved depression and learning. This study illustrates how brain injury can affect multiple linked aspects of functioning and provides preliminary evidence that intensive rapid-resisted training has specific positive effects on dynamic balance and more generalized effects on sleep quality in TBI.

  9. Physeal involvement in chronic recurrent multifocal osteomyelitis

    International Nuclear Information System (INIS)

    Chronic recurrent multifocal osteomyelitis is a recently recognized disease characterized by remissions and exacerbations of multiple bone lesions which radiographically and pathologically have the appearance of hematogenous osteomyelitis. No consistent etiology can be identified, and antimicrobial agents seem to have no beneficial effect. A review of the appearances on imaging modalities and the clinical and pathologic manifestations is undertaken in seven cases of CRMO. No therapeutic regimen resulted in consistent clinical or radiographic improvement. We suggest the sequelae of this process are not as benign as previously reported. (orig.)

    Branding is a form of body art wherein third-degree burns are inflicted on the skin to produce permanent scars. This method of scarification is a common practice among many indigenous cultures and has become exceedingly common in western societies. As with other forms of body art, branding is not a manifestation of a psychiatric disorder but, rather, a method of self-expression. The process can be performed through the use of electrocautery, laser, chemicals, freezing, and hot metal. Complications arising from the procedure include acute infection, transmission of blood-borne pathogens, allergic reactions, and sequelae arising from third-degree burns. In addition, skin branding has been shown to be associated with substance abuse and high-risk behaviors among adolescents. The purpose of this article is to present the following case report and review to familiarize clinicians with this dangerous method of body art.

    We report a 7-year-old girl with hemophagocytic lymphohistiocytosis and an uncommon complication of vascular retinopathy and visual sequelae. She was also verified to be complicated with dysfibrinogenemia. The patient was treated with etoposide, dexamethasone, and cyclosporin A. During the fifth hospital week, a generalized tonic-clonic convulsion developed followed by deep coma. When she regained full consciousness, she complained of a visual disturbance. The ophthalmologic examination showed bilateral extensive retinal edema with numerous cotton-wool spots, indicative of vaso-occlusive retinopathy. This is inconsistent with the main finding of previous cases with ocular involvement, namely papilledema. Severely reduced visual acuity and visual field defects remained in both eyes even after systemic therapy. An awareness of this rare but serious complication is important because it may be preventable by early institution of chemotherapy. The pathogenesis of the retinopathy is also discussed.

    2010-10-01

    Cognitive ecology is the study of cognitive phenomena in context. In particular, it points to the web of mutual dependence among the elements of a cognitive ecosystem. At least three fields were taking a deeply ecological approach to cognition 30 years ago: Gibson's ecological psychology, Bateson's ecology of mind, and Soviet cultural-historical activity theory. The ideas developed in those projects have now found a place in modern views of embodied, situated, distributed cognition. As cognitive theory continues to shift from units of analysis defined by inherent properties of the elements to units defined in terms of dynamic patterns of correlation across elements, the study of cognitive ecosystems will become an increasingly important part of cognitive science.

    Little is known about the effect of migraine on neural cognitive networks. However, cognitive dysfunction is increasingly being recognized as a comorbidity of chronic pain. Pain appears to affect cognitive ability and the function of cognitive networks over time, and decrements in cognitive function can exacerbate affective and sensory components of pain. We investigated differences in cognitive processing and pain–cognition interactions between 14 migraine patients and 14 matched healthy con...

    Full Text Available Tuberculosis meningitis (TBM is common CNS infection associated with neurologic sequelae and mortality if untreated. Recommended treatment regimen consists; two months of daily Isoniazide (INH, Rifampin (RIF, Pyrazinamide (PZA and either Streptomycin (SM or Ethambutol (EMB followed by 7–10 months of INH and RIF. Optic atrophy as neurologic complication may develop in TBM patients with anti TB therapy. Infection and/or drugs can be an etiologic factor also. In this case patient was diagnosed with TBM at the age of three years and was on anti TB drugs. At the age of four years he was completely cured from TBM but developed seizure as neurologic sequelae. Provisionally, child was diagnosed as known case of TBM with seizures and visual defect. Ophthalmologist revealed; bilateral optic atrophy and Neurophysician confirmed as Neurological sequelae and bilateral optic atrophy developed due to TBM treatment. A thorough patient history including past medication history is a clinical pearl to identify such rare clinical complication. In this case optic atrophy and neurological sequelae was confirmed only after thorough history and evaluation by various specialists. Not only confirmation of rare clinical syndrome is important, also identification of possible etiology and appropriate management is required for better management. Clinical pharmacists play a crucial role even in identification and reporting of such rare clinical condition as a part of health care system to create awareness among others.

    @@ Infection of hepatitis B virus (HBV) is ubiquitous although the prevalence of hepatitis B surface antigen (HBsAg) varies considerably worldwide. Persistent HBV infection may lead to severe sequelae such as cirrhosis and hepatocellular carcinoma. Thus, clarification of the mechanism of susceptibility to persistent HBV infection would be valuable for the prevention and treatment of chronic hepatitis B.

  4. Chronic inflammatory systemic diseases: An evolutionary trade-off between acutely beneficial but chronically harmful programs.

    2016-01-01

    It has been recognized that during chronic inflammatory systemic diseases (CIDs) maladaptations of the immune, nervous, endocrine and reproductive system occur. Maladaptation leads to disease sequelae in CIDs. The ultimate reason of disease sequelae in CIDs remained unclear because clinicians do not consider bodily energy trade-offs and evolutionary medicine. We review the evolution of physiological supersystems, fitness consequences of genes involved in CIDs during different life-history stages, environmental factors of CIDs, energy trade-offs during inflammatory episodes and the non-specificity of CIDs. Incorporating bodily energy regulation into evolutionary medicine builds a framework to better understand pathophysiology of CIDs by considering that genes and networks used are positively selected if they serve acute, highly energy-consuming inflammation. It is predicted that genes that protect energy stores are positively selected (as immune memory). This could explain why energy-demanding inflammatory episodes like infectious diseases must be terminated within 3-8 weeks to be adaptive, and otherwise become maladaptive. Considering energy regulation as an evolved adaptive trait explains why many known sequelae of different CIDs must be uniform. These are, e.g. sickness behavior/fatigue/depressive symptoms, sleep disturbance, anorexia, malnutrition, muscle wasting-cachexia, cachectic obesity, insulin resistance with hyperinsulinemia, dyslipidemia, alterations of steroid hormone axes, disturbances of the hypothalamic-pituitary-gonadal (HPG) axis, hypertension, bone loss and hypercoagulability. Considering evolved energy trade-offs helps us to understand how an energy imbalance can lead to the disease sequelae of CIDs. In the future, clinicians must translate this knowledge into early diagnosis and symptomatic treatment in CIDs. PMID:26817483

    2014-01-01

    Background: Chronic obstructive pulmonary disease (COPD) is a costly long-term condition associated with frequent Accident and Emergency (A&E) and hospital admissions. Psychological difficulties and inadequate self-management can amplify this picture. Aims: To compare a cognitive-behavioural manual versus information booklets (IB) on health service use, mood and health status. Methods: Two hundred and twenty-two COPD patients were randomly allocated to receive either the COPD breathlessness manual (CM) or IB. They were instructed to work through their programme at home, over 5 weeks. Guidance from a facilitator was provided at an initial home visit plus two telephone call follow-ups. Results: After 12 months, total A&E visits had reduced by 42% in the CM group, compared with a 16% rise in the IB group. The odds of people in the IB group attending A&E 12 months post-intervention was 1.9 times higher than for the CM group (CI 1.05–3.53). Reduction in hospital admissions and bed days were greatest in the CM group. At 6 months, there were significantly greater improvements in anxiety (F (2,198)=5.612, P=0.004), depression (F (1.8,176.1)=10.697, P⩽0.001) and dyspnoea (F (2,198)=18.170, P⩽0.001) in the CM group. Estimated savings at 12 months were greatest in the CM group, amounting to £30k or £270 per participant. Conclusion: The COPD manual, which addresses physical and mental health, is a straightforward cost-effective intervention that is worth offering to COPD patients within primary or secondary care.

    2016-06-01

    : More than 12% of women will be diagnosed with breast cancer at some point in their lives, and 78% of them can be expected to survive for at least 15 years. More than 2.8 million breast cancer survivors currently reside in the United States. After breast cancer treatment, as many as 90% of survivors report physical problems that can reduce functional ability, produce or exacerbate emotional problems, negatively affect body image, and diminish quality of life. Many survivors will seek care for late and long-term effects of treatment, which will not necessarily be recognized as such by health care providers and appropriately treated. In this article, the authors discuss the underlying causes of late and long-term sequelae of breast cancer treatment and describe effective assessment and management strategies. They focus specifically on the most common and potentially debilitating upper body effects of breast cancer surgery and external radiation therapy: lymphedema, axillary web syndrome, postmastectomy pain syndrome, rotator cuff syndrome, adhesive capsulitis, arthralgias, cervical radiculopathy, and brachial plexopathy.

    Reverse shoulder arthroplasty (RSA) represents an established procedure for treatment of fracture sequelae (FS) after proximal humerus fractures. The present work evaluates which factors are of influence for the clinical outcome. Fifty cases (mean age 69, range 44-89) have been evaluated postoperatively clinically [Constant Score (CS)] and radiographically (mean FU 34; range 24-93 months). The type of primary treatment, the amount of a metaphyseal bone defect, the preoperative status of the rotator cuff, the number of previous operative interventions and the type of FS according to Boileau were analysed whether they are of influence for clinical outcome. The mean CS increased significantly from 16.9 ± 6.7 preoperatively to 54.1 ± 15.7 points postoperatively. The CS of primary conservative treatment was significantly higher in comparison to primary operative treatment. Patients with a metaphyseal bone defect of more than 3 cm had significantly lower CS results. Degenerative changes of the teres minor muscle also had a significant negative influence on clinical results. Score results decreased with increasing number of previous operations. There were no significant difference in between patients classified as Boileau type I and II (category 1) compared to types III and IV (category 2). RSA significantly improved the clinical result. A metaphyseal bone defect and preoperative degeneration of the teres minor showed to be negative prognostic factors. Primary operative treatment and the number of previous operations also negatively influenced the clinical result.

    A number of people injured during the second world war harbour foreign bodies such as grenade splinters or bullets in some part of the body. Most of these metal fragments remain clinically silent. Some of them, however, may cause delayed complications. The purpose of this study was to determine the characteristics of delayed complications associated with foreign bodies after world war II injuries. 159 patients with retained foreign bodies after world war II injuries were retrospectively identified radiologically in our data bases in the time interval from 1997 to 2009. Diverse delayed complications secondary to the metal objects were diagnosed in 3 cases (2%): one patient with grenade splinter migration into the choledochal duct, one case with pseudotumoural tissue reaction, and one patient with late osteomyelitis. The time from injury to clinical presentation varied from 56 to 61 years. PubMed and Medline were screened for additional cases with delayed sequelae after foreign body acquisition during the 2nd world war. A 30 year search period from 1980 up to date was selected. 15 cases were identified here. Our study demonstrates that health consequences of the 2nd world war extend into the present time, and therefore physicians should be aware of the presence of hidden foreign bodies and their different possible late reactions.

    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. PMID:3343496

  16. Evaluation of some oral postradiotherapy sequelae in patients treated for head and neck tumors

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate the oral sequelae of radiotherapy in patients treated between 1999 and 2003 for head and neck tumors. One-hundred patients (24 women, 76 men) ranging in age from 30 to 83 years (mean 59.2 years) were examined. Time since radiotherapy ranged from 1 to 72 months (mean 28 months). The total mean radiation dose received by the patients was 5,955 cGy. The evaluation protocol included anamnesis, intraoral and extraoral examination, measurement of stimulated salivary flow and salivary pH. Symptoms reported by the patients included dry mouth (68%), dysphagia (38%), and dysgeusia (30%). In 64% of the patients, the mean stimulated salivary flow rate was less than 0.7 ml/min. The mean salivary pH was 6.97 (± 0.714). Stimulated salivary flow increased with increasing postradiotherapy time (p < 0.05). The prevalence of mucositis was associated with higher radiation doses (p < 0.05), and the prevalence of atrophic candidiasis was related to a longer post-treatment period (p < 0.05). Two cases of recurrence of the primary tumor were detected during the study. The main effect of radiotherapy in the head and neck region was a reduction of the salivary flow rate, even though our study demonstrated that there was a modest late improvement of the salivary flow.

  17. Late cardiac, thyroid, and pulmonary sequelae of mantle radiotherapy for Hodgkin's disease

    International Nuclear Information System (INIS)

    Cardiac, thyroid and pulmonary function were evaluated in 25 patients aged 35 years or under, treated for Hodgkin's disease by mantle radiotherapy 5-16 years previously. No patient had symptoms of heart disease. Although thallium myocardial perfusion scintigraphy was normal in all patients, abnormalities of myocardial function were detected in 6 (24%) patients using gated equilibrium rest and exercise radionuclide ventriculography. Resting left ventricular ejection fraction (LVEF) was abnormal in 1 patient, and in 3 patients there was an abnormal LVEF response to exercise. All 6 patients had right ventricular dilatation. Apical hypokinesia was present in 4 of these patients. A small asymptomatic pericardial effusion was detected by M-Mode echocardiography in only 2 (8%) patients. Twenty-three (92%) patients had evidence of abnormal thyroid function. Two (8%) patients had become clinically hypothyroid. Serum TSH was elevated in 13 (52%) patients and TRH stimulation test was abnormal in a further 10 (40%) patients in whom TSH was normal. Pulmonary function studies showed a moderate decrease in diffusing capacity (72% of predicted) and a minor reduction in lung volume. Although a high incidence of cardiac, thyroid and pulmonary abnormalities was detected, only the 2 patients who had become hypothyroid were symptomatic. Modification of the irradiation technique may reduce the incidence of cardiac abnormalities, but is unlikely to alter significantly the thyroid or pulmonary sequelae

    This article evaluated the common physical sequelae that affect return to work (RTW) after traumatic brain injury (TBI). We performed a Medline search and evaluation of current TBI rehabilitation texts. The information presented is a combination of published literature and clinical guidelines. The limitations faced by many patients with TBI can best be overcome through clever job search, job redesign, and community linkages with business and industry that are willing to partner in helping the patient with TBI regain employment. The physician plays a key role in communicating suggestions to the vocational specialist. The comorbidities described represent challenges to successful RTW. These problems are recurrent, long-term, and clearly affect job procurement, nature of job, level of required support, and likelihood of job retention. Conversely, these challenges should not be viewed as impenetrable obstacles. With appropriate supports such as compensatory strategies, job coaching, assistive technology, medical management, and job restructuring, successful RTW is viable option. Physicians must focus on employment outcomes in real jobs and not settle for volunteer work, sheltered work, or assessment and planning. Individuals should be placed in real work for real pay. Through close collaboration between the survivor of TBI, the physician, the vocational specialist, and community resources, successful employment for survivors of TBI is possible and must be prescribed a high value.

    2013-01-01

    Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is a sporadically occurring, acquired neuropathic condition of autoimmune origin with chronic progressive or relapsing-remitting disease course. CIDP is a treatable disorder; a variety of immunosuppressive and immunomodulatory agents are available to modify, impede, and even reverse the neurological deficits and sequelae that manifest in the course of the disease. However, in many cases CIDP is not curable. Challenges that remain in the treatment of CIDP patients are well recognized and include a remarkably individual heterogeneity in terms of disease course and treatment response as well as a lack of objective and feasible measures to predict and monitor the responsiveness to the available therapies. In this chapter an overview of the currently used drugs in the treatment of CIDP patients is given and some important and controversial issues that arise in the context of care for CIDP patients are discussed.

    Full Text Available Vascular pathology of the brain is the second most common cause of cognitive impairment after Alzheimer's disease. The article describes the modern concepts of etiology, pathogenetic mechanisms, clinical features and approaches to diagnosis and therapy of vascular cognitive impairment (VCI. Cerebrovascular accident, chronic cerebral circulatory insufficiency and their combination, sometimes in combination with a concomitant neurodegenerative process, are shown to be the major types of brain lesions leading to VCI. The clinical presentation of VCI is characterized by the neuropsychological status dominated by impairment of the executive frontal functions (planning, control, attention in combination with focal neurological symptoms. The diagnosis is based on comparing of the revealed neuropsychological and neurological features with neuroimaging data. Neurometabolic, acetylcholinergic, glutamatergic, and other vasoactive drugs and non-pharmacological methods are widely used to treat VCI. 

  3. The impact of otitis media on cognitive and educational outcomes.

    2009-11-01

    Otitis media is a common disease in childhood that can adversely affect cognitive and educational outcomes. The literature in this area is equivocal, and findings may be influenced by research design. The impact of otitis media on individual children's development appears to depend on the inter-relationship between several factors. Children who have early-onset otitis media (under 12 months) are at high risk of developing long-term speech and language problems. Otitis media has been found to interact negatively with pre-existing cognitive or language problems. For biological or environmental reasons, some populations have a pattern of early onset, higher prevalence and episodes of longer duration; this pattern leads to a higher risk of long-term speech and language problems. These factors suggest that Indigenous children may be at higher risk of cognitive and educational sequelae than non-Indigenous children.

    This collection of research papers on visual cognition first appeared as a special issue of Cognition: International Journal of Cognitive Science. The study of visual cognition has seen enormous progress in the past decade, bringing important advances in our understanding of shape perception, visual imagery, and mental maps. Many of these discoveries are the result of converging investigations in different areas, such as cognitive and perceptual psychology, artificial intelligence, and neuropsychology. This volume is intended to highlight a sample of work at the cutting edge of this research area for the benefit of students and researchers in a variety of disciplines. The tutorial introduction that begins the volume is designed to help the nonspecialist reader bridge the gap between the contemporary research reported here and earlier textbook introductions or literature reviews.

    Phencyclidine (PCP) induces a behavioural syndrome in rodents that bears remarkable similarities to some of the core symptoms observed in schizophrenic patients, among those cognitive deficits. The successful alleviation of cognitive impairments associated with schizophrenia (CIAS) has become a major focus of research efforts as they remain largely untreated. The aim of the present study was to investigate the effects of selected antipsychotic and cognition enhancing drugs, namely haloperidol...

    Objective: To observe the effect of acupuncture on blood oxygen free radical (OFR) and nitric oxide(NO) levels in the treatment of apoplectic sequelae. Methods: A total of 61 cases of apoplectic patients were subject-ed into this study and randomly divided into "JIN San Zhen" group (n=30) and control group (n=31). Blood lipid per-oxidase (LPO), superoxide dismutase (SOD), glutathione peroxidase(GSH-Px) and nitric oxide (NO) contents beforeand after acupuncture treatment were determined with radioimmunoassay. In both groups, acupuncture was given oncedaily, six times a week, with 4 weeks being a therapeutic course and with the interval between two weeks being aweek, 3 courses all together. In "JIN San Zhen" group, acupoints of "JIN San Zhen" were used predominately, whilein control group, scalp-point Motor Sensory Area (MS 8) was used as the main point. Results: Self-comparison showedthat after 3 courses of treatment, in both groups, LPO and NO levels decreased significantly ( P < 0.05 - 0.01 ), SODand GST-Px values increased considerably ( P< 0.05 - 0.01 ). Comparison between two groups indicated that the ef-fects of "JIN San Zhen" group are significantly superior to those of control group in raising blood SOD and GST-Px lev-els ( P< 0.05- 0.01 ) and in lowering blood NO content ( P< 0.01 ). Analysis on the correlation between the restora-tion of neural function and the changes of LPO, SOD and GST-Px levels suggested that the effect of acupuncture in im-proving neural function may be related to changes of the aforementioned indexes. Conclusion: Acupuncture therapy cansignificantly lower blood LPO and NO levels and evidently raise blood SOD and GST-Px levels in stroke patients.

    Introduccion. Las alteraciones cognitivas y emocionales asociadas al insomnio cronico son poco conocidas. Desarrollo. Tras revisar la etiologia y fisiopatologia del insomnio cronico, considerando la vulnerabilidad a este y su heredabilidad, se describe el estado actual de conocimientos acerca de los deficits cognitivos y las alteraciones emocionales observados en el insomnio cronico. Conclusiones. La mayoria de los modelos etiologicos incluye factores que predisponen al insomnio, que lo precipitan y que lo mantienen. Los factores predisponentes pueden ser de tipo biologico o psicosocial. Un factor predisponente que desempeña un importante papel es la vulnerabilidad al insomnio, que se relaciona con un modo no adaptativo de afrontar el estres (centrado en la emocion en vez de en el problema) y la internalizacion de las emociones negativas, lo cual favorece un estado de hiperactivacion fisiologica, cognitiva y emocional que altera el sueño y puede desembocar en insomnio. Esta vulnerabilidad es en gran parte hereditaria. Se han descrito dos fenotipos, basados en la duracion objetiva del sueño, que difieren en la gravedad del trastorno. Los insomnes con duracion objetiva del sueño menor de seis horas presentan deficits cognitivos significativos. Estos se manifiestan en tareas que requieren gran cantidad de recursos cognitivos, tareas de atencion complejas, cambio de foco de atencion, proceso de consolidacion de la memoria durante el sueño y memoria operativa. Estos datos sugieren la existencia de una disfuncion prefrontal. Se da una alta comorbilidad entre insomnio y ansiedad-depresion. La ansiedad-depresion provocada por la internalizacion de las emociones predispone al insomnio, y este, a su vez, intensifica la depresion.

  11. The woodchuck as an animal model for pathogenesis and therapy of chronic hepatitis B virus infection

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    This review describes the woodchuck and the woodchuck hepatitis virus (WHV) as an animal model for pathogenesis and therapy of chronic hepatitis B virus (HBV) infection and disease in humans. The establishment of woodchuck breeding colonies, and use of laboratory-reared woodchucks infected with defined WHV inocula, have enhanced our understanding of the virology and immunology of HBV infection and disease pathogenesis, including major sequelae like chronic hepatitis and hepatocellular carcinoma. The role of persistent WHV infection and of viral load on the natural history of infection and disease progression has been firmly established along the way. More recently, the model has shed new light on the role of host immune responses in these natural processes,and on how the immune system of the chronic carrier can be manipulated therapeutically to reduce or delay serious disease sequelae through induction of the recovery phenotype. The woodchuck is an outbred species and is not well defined immunologically due to a limitation of available host markers. However, the recent development of several key host response assays for woodchucks provides experimental opportunities for further mechanistic studies of outcome predictors in neonatal- and adult-acquired infections. Understanding the virological and immunological mechanisms responsible for resolution of self-limited infection, and for the onset and maintenance of chronic infection, will greatly facilitate the development of successful strategies for the therapeutic eradication of established chronic HBV infection. Likewise, the results of drug efficacy and toxicity studies in the chronic carrier woodchucks are predictive for responses of patients chronically infected with HBV. Therefore, chronic WHV carrier woodchucks provide a well-characterized mammalian model for preclinical evaluation of the safety and efficacy of drug candidates, experimental therapeutic vaccines, and immunomodulators for the treatment and

    Cardiac arrest is associated with a number of cognitive processes as well as long term psychological outcomes. Recent studies have indicated that approximately 10-20% of cardiac arrest survivors report cognitive processes, including the ability to recall specific details of their resuscitation from the period of cardiac arrest. In addition it has been demonstrated that these cognitive processes are consistent with the previously described near death experience and that those who have these experiences are left with long term positive life enhancing effects. There have also been numerous studies that have indicated that although the quality of life for cardiac arrest survivors is generally good, some are left with long term cognitive impairments as well as psychological sequelae such as post-traumatic stress disorder. This paper will review near death experiences, cognitive function and psychological outcomes in survivors of cardiac arrest.

    Full Text Available El dolor crónico constituye un grave problema de salud pública, dada su elevada prevalencia y las consecuencias personales y sociales que produce. La presencia de dolor crónico se ha asociado con un deterioro cognitivo leve, sobre todo en los pacientes afectados por fibromialgia o dolor neuropático, habiéndose relacionado esto con la concurrencia en estos pacientes, de otros procesos, como la ansiedad, la depresión, los trastornos del sueño y el consumo de ciertos fármacos, todos ellos habituales en los pacientes con dolor crónico. En esta revisión, hacemos un repaso del complejo proceso de la cognición así como de los distintos elementos que lo integran. Asimismo, revisamos los mecanismos mediante los que el dolor crónico puede afectar el proceso de la cognición y el modo en el que este puede verse afectado por la concurrencia de otras patologías, o por los fármacos habitualmente utilizados para su tratamiento. Finalmente se plantea la necesidad de evaluar el deterioro cognitivo en los pacientes con dolor crónico, con el objetivo de evitar la progresión de la enfermedad cognitiva hacia un cuadro de deterioro más grave, así como de contribuir a mejorar la respuesta terapéutica al dolor y el aumento de la calidad de vida de los pacientes.Chronic pain constitutes a serious public health problem due to its high prevalence and the social and personal consequences.

    Full Text Available Chronic fatigue syndrome (CFS is characterized by fatigue, sleep dysfunction, and cognitive deficits (Fukuda et al., 1994. Research surrounding cognitive functioning among patients with CFS has found difficulty with memory, attention, and information processing. A similar disorder, postural tachycardia syndrome (POTS, is characterized by increased heart rate, fatigue, and mental cloudiness (Raj et al., 2009. Potential implications of cognitive deficits for patients with CFS and/or POTS are discussed, including difficulties with school and/or employment. A few biological theories (i.e., kindling, impairments in the central nervous system, and difficulty with blood flow have emerged as potential explanations for the cognitive deficits reported in both CFS and POTS Future research should continue to examine possible explanations for cognitive impairments in CFS and POTS, and ultimately use this information to try and reduce cognitive impairments for these patients.

  20. Offloading Cognition onto Cognitive Technology

    Dror, Itiel

    2008-01-01

    "Cognizing" (i.e., thinking, understanding, knowing, and having the capacity to do what cognizers can do) is a mental state. Systems without mental states, such as cognitive technology, can sometimes also do some of what cognizers can do, but that does not make them cognizers. Cognitive technology allows cognizers to offload some of the functions they would otherwise have had to execute with their own brains and bodies alone; it also extends cognizers' performance powers beyond those of brains and bodies alone. Language itself is a form of cognitive technology that allows cognizers to offload some of their brain functions onto the brains of other cognizers. Language also extends cognizers' individual and joint performance powers, distributing the load through interactive and collaborative cognition. Reading, writing, print, telecommunications and computing further extend cognizers' capacities. And now the web, with its distributed network of cognizers, digital databases and sofware agents, has become the Cogn...

    Acne, psoriasis and atopic eczema are common diseases and have been consistently associated with adverse psychological sequelae including stigmatization. Being teased on the basis of appearance has been associated with psychiatric morbidity in children and adolescents. The objective of this qualitative study was to explore the experiences of teasing and bullying in patients with acne, psoriasis and eczema, and the role of appearance-related teasing and bullying as mediators of psychological morbidity in these patients. Data collection consisted of 62 in-depth semi-structured interviews with patients with acne, psoriasis or atopic eczema recruited from both specialist dermatology and general practices. Data analysis was cumulative and concurrent throughout the data collection period reflecting a grounded theory approach. Analysis followed the analytic induction method, allowing themes to emerge from the data. Teasing, taunting or bullying was a considerable problem for a significant minority of acne, psoriasis and atopic eczema participants. Themes that emerged were the universally negative nature of the teasing, the use of teasing as an instrument of social exclusion, and as a means of establishing or enforcing power relationships, teasing related to contagion and fear, the emotional and psychological sequelae of teasing and the theme of 'insensate' teasing. For those who had suffered teasing or bullying, this was causally linked in respondents' accounts with psychological sequelae, especially self-consciousness and effects on self-image and self-esteem. Experiences of teasing and bullying were found to have principally occurred during the adolescence of participants and the perpetrators were other adolescents, but there were findings of respondents with psoriasis also having been subjected to ridicule or derogatory remarks by health professionals. Teasing, taunting and bullying may represent an underappreciated source of psychological morbidity in children and

    The immunopathogenesis of Chlamydia trachomatis-induced oviduct pathological sequelae is not well understood. Mice genetically deficient in perforin (perforin(-/-) mice) or tumor necrosis factor alpha (TNF-α) production (TNF-α(-/-) mice) displayed comparable vaginal chlamydial clearance rates but significantly reduced oviduct pathology (hydrosalpinx) compared to that of wild-type mice. Since both perforin and TNF-α are effector mechanisms of CD8(+) T cells, we evaluated the role of CD8(+) T cells during genital Chlamydia muridarum infection and oviduct sequelae. Following vaginal chlamydial challenge, (i) mice deficient in TAP I (and therefore the major histocompatibility complex [MHC] I pathway and CD8(+) T cells), (ii) wild-type mice depleted of CD8(+) T cells, and (iii) mice genetically deficient in CD8 (CD8(-/-) mice) all displayed similar levels of vaginal chlamydial clearance but significantly reduced hydrosalpinx, compared to those of wild-type C57BL/6 mice, suggesting a role for CD8(+) T cells in chlamydial pathogenesis. Repletion of CD8(-/-) mice with wild-type or perforin(-/-), but not TNF-α(-/-), CD8(+) T cells at the time of challenge restored hydrosalpinx to levels observed in wild-type C57BL/6 mice, suggesting that TNF-α production from CD8(+) T cells is important for pathogenesis. Additionally, repletion of TNF-α(-/-) mice with TNF-α(+/+) CD8(+) T cells significantly enhanced the incidence of hydrosalpinx and oviduct dilatation compared to those of TNF-α(-/-) mice but not to the levels found in wild-type mice, suggesting that TNF-α production from CD8(+) T cells and non-CD8(+) cells cooperates to induce optimal oviduct pathology following genital chlamydial infection. These results provide compelling new evidence supporting the contribution of CD8(+) T cells and TNF-α production to Chlamydia-induced reproductive tract sequelae.

    Purpose: To define the cranial magnetic resonance imaging (MRI) features of the chronic stage of carbon monoxide (CO) poisoning in patients with and without neuropsychiatric sequelae. Material and Methods: Eight patients who had neither symptoms nor neurological sequelae and eight patients with neuropsychiatric sequelae were included in the study. Patients aged between 9 to 57 (mean 32.2 years). All patients had been comatose at initial admittance and awoke after normobaric 100% oxygen therapy within 1-7 days. In this study, the patients were being examined with routine cranial MRI between 1 and 10 years (mean 3.4 years) after exposure to CO. Results: The most common finding was bilateral symmetric hyperintensity of the white matter, which was more significant in the centrum semiovale, with relative sparing of the temporal lobes and anterior parts of the frontal lobes on T2-weighted and FLAIR images in all patients. Cerebral cortical atrophy was seen in 10 patients; mild atrophy of cerebellar hemispheres in 8; and vermian atrophy in 11. Corpus callosum was atrophic in one patient. Bilateral globus pallidus lesions were seen in three patients. The lesions were hypointense on T1-weighted images and hyperintense on T2-weighted and FLAIR images. Conclusion: Patients with severe CO intoxication may develop persistent cerebral changes independently of their neuropsychiatric findings in the chronic stage. They may present with characteristic MRI findings as described here, even if asymptomatic. The history of CO exposure is therefore helpful for recognizing and interpreting the MRI findings of chronic stage CO intoxication.

    Traumatic dental injuries (TDIs) can result in the premature loss of primary anterior teeth due to an immediate avulsion, extraction later after the injury because of poor prognosis or late complications, or early exfoliation. There are a number of potential considerations or sequelae as a result of this premature loss that have been cited in the dental literature, which include esthetics, quality of life, eating, speech development, arch integrity (space loss), development and eruption of the permanent successors, and development of oral habits. This article provides a comprehensive review of the dental literature on the possible consequences of premature loss of maxillary primary incisors following TDI.

  6. Human cognition

    International Nuclear Information System (INIS)

    The study of human cognition encompasses the study of all mental phenomena, from the receipt and interpretation of sensory information to the final control of the motor system in the performance of action. The cognitive scientist examines all intermediary processes, including thought, decision making, and memory and including the effects of motivation, states of arousal and stress, the study of language, and the effects of social factors. The field therefore ranges over an enormous territory, covering all that is known or that should be known about human behavior. It is not possible to summarize the current state of knowledge about cognition with any great confidence that we know the correct answer about any aspect of the work. Nontheless, models provide good characterizations of certain aspects of the data and situations. Even if these models should prove to be incorrect, they do provide good approximate descriptions of people's behavior in some situations, and these approximations will still apply even when the underlying theories have changed. A quick description is provided of models within a number of areas of human cognition and skill and some general theoretical frameworks with which to view human cognition. The frameworks are qualitative descriptions that provide a way to view the development of more detailed, quantitative models and, most important, a way of thinking about human performance and skill

    2013-02-01

    Chronic insomnia (symptoms for ≥ 6 months) is the most common sleep disorder, affecting 6% to 10% of adults in the general population, with even higher rates in patients with comorbid conditions (eg, hypertension, 44%; cardiac disease, 44.1%; breathing problems, 41.5%). Traditionally, chronic insomnia occurring with another condition has been considered secondary and rarely received direct treatment because treatment of the primary condition was expected to improve the insomnia. However, this approach often failed because chronic insomnia is maintained by behaviors, cognitions, and associations that patients adopt as they attempt to cope with poor sleep but that end up backfiring (eg, increasing caffeine, spending more time in bed, trying harder to sleep). Cognitive behavioral treatment of insomnia (CBTi) targets those behaviors, cognitions, and associations and is effective across a variety of populations, including those with medical and psychologic comorbidities. Thus, in 2005, a National Institutes of Health expert consensus panel on chronic insomnia recommended dropping the term "secondary insomnia" in favor of the term "comorbid insomnia." Because CBTi does not carry the risks associated with some sleep medications (eg, dependency, polypharmacy, cognitive and psychomotor impairment), it is an attractive option for patients with other conditions. Through the Society of Behavioral Sleep Medicine (www.behavioralsleep.org) and the American Board of Sleep Medicine (www.absm.org), it is possible to find practitioners with expertise in CBTi (as well as other aspects of behavioral sleep medicine) and other behavioral sleep resources. Given the currently limited number of trained practitioners, exploration of alternative delivery methods (eg, briefer protocols, self-help, Internet) to improve access to this highly effective treatment and expanded training in these treatments are warranted.

    2012-03-01

    Cognitive linguistics is one of the fastest growing and influential perspectives on the nature of language, the mind, and their relationship with sociophysical (embodied) experience. It is a broad theoretical and methodological enterprise, rather than a single, closely articulated theory. Its primary commitments are outlined. These are the Cognitive Commitment-a commitment to providing a characterization of language that accords with what is known about the mind and brain from other disciplines-and the Generalization Commitment-which represents a dedication to characterizing general principles that apply to all aspects of human language. The article also outlines the assumptions and worldview which arises from these commitments, as represented in the work of leading cognitive linguists.

    Recent neuroscientific research shows that the health of your brain isn't, as experts once thought, just the product of childhood experiences and genetics; it reflects your adult choices and experiences as well. Professors Gilkey and Kilts of Emory University's medical and business schools explain how you can strengthen your brain's anatomy, neural networks, and cognitive abilities, and prevent functions such as memory from deteriorating as you age. The brain's alertness is the result of what the authors call cognitive fitness -a state of optimized ability to reason, remember, learn, plan, and adapt. Certain attitudes, lifestyle choices, and exercises enhance cognitive fitness. Mental workouts are the key. Brain-imaging studies indicate that acquiring expertise in areas as diverse as playing a cello, juggling, speaking a foreign language, and driving a taxicab expands your neural systems and makes them more communicative. In other words, you can alter the physical makeup of your brain by learning new skills. The more cognitively fit you are, the better equipped you are to make decisions, solve problems, and deal with stress and change. Cognitive fitness will help you be more open to new ideas and alternative perspectives. It will give you the capacity to change your behavior and realize your goals. You can delay senescence for years and even enjoy a second career. Drawing from the rapidly expanding body of neuroscience research as well as from well-established research in psychology and other mental health fields, the authors have identified four steps you can take to become cognitively fit: understand how experience makes the brain grow, work hard at play, search for patterns, and seek novelty and innovation. Together these steps capture some of the key opportunities for maintaining an engaged, creative brain. PMID:18159786

    1984-05-01

    Chronicity in psychopathology is indicative of a term, a decay. Chronicization only leads the way to this term. Here, chronicization is taken literally as an inscription in the time course of delusions. The mechanism of systematization seems to be a central mark in the approach to chronic delusions. It is not an alienation or an irreversible closing but an attempted accommodation with reality in the life of psychotic subjects, irrespective of the delusional structure. The role of therapy and drug treatment as a follow-up may in that case assume another meaning.

    Leg discrepancy is common after poliomyelitis. Tibial lengthening is an effective way to solve this problem. It is believed lengthening over a tibial intramedullary nail can provide a more comfortable lengthening process than by the conventional technique. However, patients with sequelae of poliomyelitis typically have narrow intramedullary canals allowing limited space for inserting a tibial intramedullary nail and Kirschner wires. To overcome this problem, we tried using humeral nails instead of tibial nails in the lengthening procedure. In this study, we used humeral nails in 20 tibial lengthening procedures and compared the results with another group of patients who were treated with tibial lengthening over tibial intramedullary nails. The mean consolidation index, percentage of increase and external fixation index did not show significant differences between the two groups. However, less blood loss and shorter operating time were noted in the humeral nail group. More patients encountered difficulty with the inserted intramedullary nail in the tibial nail group procedure. The complications did not show a statistically significant difference between the two techniques on follow-up. In conclusion, we found the humeral nail lengthening technique was more suitable in leg discrepancy patients with sequelae of poliomyelitis.

    Full Text Available Myelomeningocele is a congenital malformation that affects the fetus during pregnancy. It can causes numerous consequences for the development of the child and consequently in their schooling process. So, there are several challenges that can be experienced by these children in their inclusion at school. The use of assistive technology in the school context has been implanted with goal to high from the functional abilities of these students. In Brazil are conducted a lot of studies to know the reality of children with myelomeningocele. Therefore, the goal of this study was to investigate, from the teacher ́s perspective of regular and multifunctional class, as was the process of schooling for students with myelomeningocele sequelae and resource utilization of assistive technology in the school context. The participants of this research were seven teachers and four students with myelomeningocele sequels enclosed in regular scholl.The researcher confectioned the instruments used in interviews. Data were analyzed using content of interview analysis. The results reveal that there are present challenges for inclusion of students with myelomeningocele sequelae and that teachers did not use assistive technology resources at school. It is considered that for the real practice of educational inclusion of these students the knowledge about meningomyelocele and various technologies that can be used in the school context must be published.

    Taylor's (1983) cognitive adaptation theory posits that when people go through life transitions, such as being diagnosed with a chronic disease, they adjust to their new reality. The adjustment process revolves around three themes: search for positive meaning in the experience or optimism, attempt to regain a sense of mastery in life, as well as an effort to enhance self-esteem. In the sample of 57 patients with nonmelanoma skin cancer the Cognitive Adaptation Index successfully predicted participants' distress (p accounting for 60% of the variance and lending support for the Taylor's theory of cognitive adaptation in this population.

    Full Text Available The global prevalence of physiologically defined chronic obstructive pulmonary disease (COPD in adults aged >40 yr is approximately 9-10 per cent. Recently, the Indian Study on Epidemiology of Asthma, Respiratory Symptoms and Chronic Bronchitis in Adults had shown that the overall prevalence of chronic bronchitis in adults >35 yr is 3.49 per cent. The development of COPD is multifactorial and the risk factors of COPD include genetic and environmental factors. Pathological changes in COPD are observed in central airways, small airways and alveolar space. The proposed pathogenesis of COPD includes proteinase-antiproteinase hypothesis, immunological mechanisms, oxidant-antioxidant balance, systemic inflammation, apoptosis and ineffective repair. Airflow limitation in COPD is defined as a postbronchodilator FEV1 (forced expiratory volume in 1 sec to FVC (forced vital capacity ratio <0.70. COPD is characterized by an accelerated decline in FEV1. Co morbidities associated with COPD are cardiovascular disorders (coronary artery disease and chronic heart failure, hypertension, metabolic diseases (diabetes mellitus, metabolic syndrome and obesity, bone disease (osteoporosis and osteopenia, stroke, lung cancer, cachexia, skeletal muscle weakness, anaemia, depression and cognitive decline. The assessment of COPD is required to determine the severity of the disease, its impact on the health status and the risk of future events (e.g., exacerbations, hospital admissions or death and this is essential to guide therapy. COPD is treated with inhaled bronchodilators, inhaled corticosteroids, oral theophylline and oral phosphodiesterase-4 inhibitor. Non pharmacological treatment of COPD includes smoking cessation, pulmonary rehabilitation and nutritional support. Lung volume reduction surgery and lung transplantation are advised in selected severe patients. Global strategy for the diagnosis, management and prevention of Chronic Obstructive Pulmonary Disease

    As the population getting older, the chronic diseases will be more prevalent as diabetes mellitus (DM) and diseases characterized by cognitive deficits, as dementia. Studies have already shown an association between DM and cardiovascular risk factors associated with cognitive impairment. Besides the vascular complications of DM, studies have proposed the role of hyperglycemia and advanced glycosilation end products (AGEP) causing oxidative stress and beta-amyloid protein brain deposition. Other factors have also been investigated, such as the role of insulinemia, genetic and IGF-1 (insulin-like growth factor-1). Some studies showed that good glucose control and intake of polyunsaturated fat, Omega-3 or anti-oxidative food can play a protector role against cognitive deficits. Improving knowledge about the association between DM and cognition and its physiopathology, can be essential for the prevention and treatment of cognitive impairment, leading to a beneficial impact on the quality of life of elderly patients with DM.

    2015-09-01

    The mild cognitive impairment (MCI) is described as an intermediate state of cognitive impairment whereby individuals present with mild clinical symptoms but with nearly normal daily living activities. These subjects do not meet the clinical criteria for dementia, yet their cognitive functioning is below what we would expect for age and education in healthy people. In the other hand, older adults are at risk for sleep disorders including obstructive sleep apnea syndrome, restless legs syndrome, REM sleep behavioral disorder and chronic insomnia, which could have an impact on cognitive functioning and are exclusion criteria for the MCI diagnosis. Moreover, REM sleep behavioral disorder represents a risk factor for the development of neurodegenerative diseases. In subjects more 65 years of age the association between chronic insomnia and cognitive changes is still debated. The main aim of this paper is to focus on identification of sleep disorders in the context of cognitive disturbances among professionals working with the elderly. PMID:26395305

    Posttraumatic stress disorder (PTSD) and mild traumatic brain injury (mTBI) are highly prevalent among Veterans of the conflicts in Iraq and Afghanistan. These conditions are associated with common and unique neuropsychological and neuroanatomical changes. This review synthesizes neuropsychological and neuroimaging studies for both of these disorders and studies examining their co-occurrence. Recommendations for future research, including utilizing combined neuropsychological and advanced neuroimaging techniques to study these disorders alone and in concert, are presented. It is clear from the dearth of literature that more attention in the literature should be given to examining temporal relationships between PTSD and mTBI, risk and resilience factors associated with both disorders and their co-occurrence, and mTBI-specific factors such as time since injury and severity of injury, utilizing comprehensive, yet targeted cognitive tasks.

    Cognitive computing and cognitive technologies are game changers for future engineering systems, as well as for engineering practice and training. They are major drivers for knowledge automation work, and the creation of cognitive products with higher levels of intelligence than current smart products. This paper gives a brief review of cognitive computing and some of the cognitive engineering systems activities. The potential of cognitive technologies is outlined, along with a brief description of future cognitive environments, incorporating cognitive assistants - specialized proactive intelligent software agents designed to follow and interact with humans and other cognitive assistants across the environments. The cognitive assistants engage, individually or collectively, with humans through a combination of adaptive multimodal interfaces, and advanced visualization and navigation techniques. The realization of future cognitive environments requires the development of a cognitive innovation ecosystem for the engineering workforce. The continuously expanding major components of the ecosystem include integrated knowledge discovery and exploitation facilities (incorporating predictive and prescriptive big data analytics); novel cognitive modeling and visual simulation facilities; cognitive multimodal interfaces; and cognitive mobile and wearable devices. The ecosystem will provide timely, engaging, personalized / collaborative, learning and effective decision making. It will stimulate creativity and innovation, and prepare the participants to work in future cognitive enterprises and develop new cognitive products of increasing complexity. http://www.aee.odu.edu/cognitivecomp

    Chronic cerebral hypoperfusion (CCH) is a common condition associated with the development and/or worsening of age-related dementia.We previously reported persistent memory loss and neurodegeneration after CCH in middle-aged rats. Statin-mediated neuroprotection has been reported after acute cerebral ischemia. Unknown, however, is whether statins can alleviate the outcome of CCH. The present study investigated whether atorvastatin attenuates the cognitive and neurohistological outcome of CCH. Rats (12–15 months old) were trained in a non-food-rewarded radial maze, and then subjected to CCH. Atorvastatin (10 mg/kg, p.o.) was administered for 42 days or 15 days, beginning 5 h after the first occlusion stage. Retrograde memory performance was assessed at 7, 14, 21, 28, and 35 days of CCH, and expressed by “latency,” “number of reference memory errors” and “number of working memory errors.” Neurodegeneration was then examined at the hippocampus and cerebral cortex. Compared to sham, CCH caused profound and persistent memory loss in the vehicle-treated groups, as indicated by increased latency (91.2% to 107.3%) and number of errors (123.5% to 2508.2%), effects from which the animals did not spontaneously recover across time. This CCH-induced retrograde amnesia was completely prevented by atorvastatin (latency: −4.3% to 3.3%; reference/working errors: −2.5% to 45.7%), regardless of the treatment duration. This effect was sustained during the entire behavioral testing period (5 weeks), even after discontinuing treatment. This robust and sustained memory-protective effect of atorvastatin occurred in the absence of neuronal rescue (39.58% to 56.45% cell loss). We suggest that atorvastatin may be promising for the treatment of cognitive sequelae associated with CCH.

    Intimate partner violence (IPV) is a global public health and human rights problem that causes physical, sexual and psychological harms to men and women. IPV includes physical aggression, sexual coercion, psychological abuse and/or controlling behaviours perpetrated by a current or previous intimate partner in a heterosexual or same-sex relationship. IPV affects both men and women, but women are disproportionately affected with nearly one third reporting IPV during their lifetime. Physical and sexual harms from IPV include injury, increased risk for sexually transmitted diseases, pregnancy complications and sometimes death. Psychological consequences include depression, anxiety, posttraumatic stress disorder, substance abuse, impulsivity and suicidality and non-specific physical complaints thought to be related to the traumatic nature and chronic stress of IPV. Children who witness IPV are also negatively impacted in the short and long term. This paper reviews prevalence, risk factors, adverse effects and current evidence-based mental health treatment advice for IPV victims. PMID:26711508

    The Hilbert space structure of classical field theory is proposed as a general theoretical framework to model human cognitive processes which do not often follow classical (Bayesian) probability principles. This leads to an extension of the circumplex model of affect and a Poincar\\'{e} sphere representation. A specific toy field theoretic model of the brain as a coherent structure in the presence of noise is also proposed that agrees qualitatively with Pavlovian fear conditioning studies.

    Children's air pollution exposures are associated with systemic and brain inflammation and the early hallmarks of Alzheimer's disease (AD). The Apolipoprotein E (APOE) 4 allele is the most prevalent genetic risk for AD, with higher risk for women. We assessed whether gender, BMI, APOE and metabolic variables in healthy children with high exposures to ozone and fine particulate matter (PM2.5) influence cognition. The Wechsler Intelligence Scale for Children (WISC-R) was administered to 105 Mexico City children (12.32±5.4 years, 69 APOE 3/3 and 36 APOE 3/4). APOE 4v 3 children showed decrements on attention and short-term memory subscales, and below-average scores in Verbal, Performance and Full Scale IQ. APOE 4 females had higher BMI and females with normal BMI between 75-94% percentiles had the highest deficits in Total IQ, Performance IQ, Digit Span, Picture Arrangement, Block Design and Object Assembly. Fasting glucose was significantly higher in APOE 4 children p=0.006, while Gender was the main variable accounting for the difference in insulin, HOMA-IR and leptin (p75% to <94% BMI percentiles are at the highest risk of severe cognitive deficits (1.5-2SD from average IQ). Young female results highlight the urgent need for gender-targeted health programmes to improve cognitive responses. Multidisciplinary intervention strategies could provide paths for prevention or amelioration of female air pollution targeted cognitive deficits and possible long-term AD progression.

    The older patient population is growing rapidly around the world and in the USA. Almost half of seniors over age 65 who live at home are dissatisfied with their sleep, and nearly two-thirds of those residing in nursing home facilities suffer from sleep disorders. Chronic and pervasive sleep complaints and disturbances are frequently associated with excessive daytime sleepiness and may result in impaired cognition, diminished intellect, poor memory, confusion, and psychomotor retardation all of which may be misinterpreted as dementia. The key sleep disorders impacting patients with dementia include insomnia, hypersomnolence, circadian rhythm misalignment, sleep disordered breathing, motor disturbances of sleep such as periodic leg movement disorder of sleep and restless leg syndrome, and parasomnias, mostly in the form of rapid eye movement (REM) sleep behavior disorder (RBD). RBD is a pre-clinical marker for a class of neurodegenerative diseases, the "synucleinopathies", and requires formal polysomnographic evaluation. Untreated sleep disorders may exacerbate cognitive and behavioral symptoms in patients with dementia and are a source of considerable stress for bed partners and family members. When left untreated, sleep disturbances may also increase the risk of injury at night, compromise health-related quality of life, and precipitate and accelerate social and economic burdens for caregivers.

    Full Text Available HIV-positive children and adolescents are at increased risk of both central nervous system (CNS sequelae and mental disorders owing to a number of factors, including the impact of HIV infection on the brain, social determinants of health (e.g. poverty and orphanhood and psychosocial stressors related to living with HIV. Every effort should be made to identify perinatally HIV-infected children and initiate them on antiretroviral therapy early in life. HIV clinicians should ideally screen for mental health and neurocognitive problems, as part of the routine monitoring of children attending antiretroviral clinics. This guideline is intended as a reference tool for HIV clinicians to support the early identification, screening and management of mental health disorders and/or CNS impairment in children and adolescents. This guideline covers mental disorders (section 1 and HIV-associated neurocognitive disorders (section 2 among children and adolescents.

    Atraumatic distal clavicular osteolysis (DCO) has been described in adult male weightlifters. Our purpose was to investigate the frequency, magnetic resonance imaging (MRI) characteristics, risk factors, and long-term sequelae of DCO in young patients. Individuals with atraumatic DCO were identified in a retrospective review of 1,432 consecutive MRI shoulder reports in patients between 13 and 19 years of age. MRI findings of DCO, association with athletic activity, short-term clinical outcome after 3-6 months, and long-term clinical and MRI outcome after 2 years were analyzed. A pre-MRI questionnaire assessed the patients' athletic history including overhead activity and weightlifting. At a mean age of 15.9 years, 6.5 % (93/1432) of patients had atraumatic DCO, and 24 % were females. The combination of an overhead sport (basketball, volleyball, tennis, swimming) and supplemental weight training was a risk factor for DCO (odds ratio = 38, p = 0.01). Ninety-three percent of patients responded to conservative therapy. On follow-up imaging, 71 % of DCO patients had acromioclavicular (AC) joint osteoarthritis (vs. 35 % in controls, p = 0.006); 79 % had flattening of the distal clavicle and interval widening of the AC joint to a mean of 5.0 mm (compared to 2.4 mm in controls, p < 0.001). Severity of DCO edema was associated with pain (p < 0.02) at initial presentation and with AC joint osteoarthritis (p = 0.004) on follow-up. In athletic teenagers, the combination of weightlifting and overhead activity is a risk factor for atraumatic DCO, and females are affected in 24 %. Long-term sequelae include widening of the AC joint and AC joint osteoarthritis. (orig.)

    In our unit, breast cancer patients suffering mild sequelae of conservative cancer treatment receive fat transfer (lipomodelling), following a precise protocol, based on mammographic and ultrasound examinations and MRI. Available data do not seem to indicate any deleterious impact on patient outcome, notably in view of radiological images, but recurrence (or rather occurrence of new ipsilateral or contralateral cancer) is frequent. The correlation between new or recurrent breast cancer and lipomodelling is high; misinterpretations are possible and frequently arise. The present paper is a description of five complex clinical cases and a discussion of the medicolegal issues that may possibly arise; it also provides tentative expert evaluation of the cases. Clinical findings are reported and analyzed. The second step is a discussion of the radiological impact of lipomodelling, and of the problems caused by the transfer of potentially malignant cells when no preoperative diagnosis of recurrence is made; the morphological and esthetic benefits of the method are described, as well as the potential beneficial impact of fat transfer, notably associated with lower breast density and injections of fat stem cells. Our conclusion is that specialized radiologists, as well as plastic surgery and oncology experts should address the question of fat transfer in operated breast cancer patients and give their reasoned opinion about potentially litigious cases. This would help minimize or solve the conflicts between patients, doctors and experts. Establishing common ground between the different stakeholders would allow the development of the technique, as lipomodelling is, according to our experience, a tremendous advance in the treatment of sequelae from conservative breast cancer surgery.

    Full Text Available Background and Objectives: According to Spanish legislation, the psychological harm suffered by the victim of a criminal act is determined by assessing its impact on the victim's mental state. Usually, the victim's pain and suffering is estimated by administering clinical scales. The aim of the present study was to explore the effectiveness of psychopathological assessment using commonly used scales in clinical practice and whose results are presented as legal evidence in a forensic context in order to detect malingered psychological sequelae (anxiety, depression and low self-esteem in victims of intimate partner violence in forensic contexts. Methods: In the present study three scales based in a clinical setting and regularly used in a forensic context were administered (BDI, STAI and Rosenberg to assess malingering of symptoms. The sample comprised 66 women: 36 students, and 30 real victims. The non-clinical sample was evaluated twice: the first time they gave sincere responses, and the second time they were instructed to answer as if they were victims. The real victims underwent testing in a forensic context. Results and Conclusions: The results of our research show that, even without previous knowledge of the scales, people can distort the test results by malingering symptoms that are normally accepted as sequelae of intimate partner violence, especially depression and low self-esteem; however, the results for anxiety, were less homogeneous. Although these tests are used extensively in clinical psychology, our study confirms that, just by themselves, they are not a reliable source of information in a forensic context.

    Apathy remains a common neuropsychiatric disturbance in the Human Immunodeficiency Virus (HIV-1) despite advances in anti-retroviral treatment (ART). The goal of the current review is to recapitulate findings relating apathy to the deleterious biobehavioral effects of HIV-1 in the post-ART era. Available literatures demonstrate that the emergence of apathy with other neurocognitive and neuropsychiatric symptoms may be attributed to neurotoxic effects of viral proliferation, e.g., aggregative effect of Tat and gp120 on apoptosis, transport and other enzymatic reactions amongst dopaminergic neurons and neuroglia. An assortment of neuroimaging modalities converge on the severity of apathy symptoms associated with the propensity of the virus to replicate within frontal-striatal brain circuits that facilitate emotional processing. Burgeoning research into functional brain connectivity also supports the effects of microvascular and neuro-inflammatory injury linked to aging with HIV-1 on the presentation of neuropsychiatric symptoms. Summarizing these findings, we review domains of HIV-associated neurocognitive and neuropsychiatric impairment linked to apathy in HIV. Taken together, these lines of research suggest that loss of affective, cognitive and behavioral inertia is commensurate with the neuropathology of HIV-1.

    Inflammatory markers are increased systematically and locally (e.g., skeletal muscle) in stroke patients. Besides being associated with cardiovascular risk factors, proinflammatory cytokines seem to play a key role in muscle atrophy by regulating the pathways involved in this condition. As such, they may cause severe decrease in muscle strength and power, as well as impairment in cardiorespiratory fitness. On the other hand, physical exercise (PE) has been widely suggested as a powerful tool for treating stroke patients, since PE is able to regenerate, even if partially, physical and cognitive functions. However, the mechanisms underlying the beneficial effects of physical exercise in poststroke patients remain poorly understood. Thus, in this study we analyze the candidate mechanisms associated with muscle atrophy in stroke patients, as well as the modulatory effect of inflammation in this condition. Later, we suggest the two strongest anti-inflammatory candidate mechanisms, myokines and the cholinergic anti-inflammatory pathway, which may be activated by physical exercise and may contribute to a decrease in proinflammatory markers of poststroke patients.

    A 16-year-old galactosemic patient, homozygous for the 5.5-kb gene deletion, suffered severe neurologic regression following streptococcal infection. Since the gene deletion includes the promoter of interleukin-11a receptor involved in neuronal apoptosis, we questioned whether this patient had no interleukin-11a receptor activity-resulting in neuronal toxicity during septicemia. We hypothesized that interleukin-11 levels would be elevated because of a loss of feedback induced by the absent interleukin-11Ra receptor complex. To assess this, we compared interleukin-11 levels in the proband and 2 of his siblings with the same genetic deletion, to age-matched controls. No differences were found in interleukin-11 levels between groups. Our study was not carried out during acute infective states, when the disrupted immunoregulation triggered by sepsis is relevant, and is thus limited. In conclusion, although interleukin-11 was not chronically elevated in individuals with galactosemia and 5.5-kb gene deletion, data do not rule out potential interleukin-11 dysfunction during acute infection.

This method is useful in the diagnosis of injuries to the spine and cord. A total of 64 patients of both sexes aged 6 to 67 were examined. The primary diagnosis of traumatic changes in the spine and cord was confirmed by MRT in only 62% of cases. Two groups of patients were singled out: with acute and chronic injuries, subdivided into subgroups with and without spinal cord dysfunction. The detected changes were divided into extramedullary (traumatic disk hernias, compression of the cord or radicles with a dislocated bone fragment, epidural hematoma) and intramedullary (edema, hemorrhages, spinal cord disruption); MRT diagnosis of intramedullary changes is particularly important, more so in the absence of bone injuries. In remote periods after the trauma the clinical picture was determined by spinal canal stenosis, cicatricial atrophic and adhesive changes eventually blocking the liquor space. Intramedullary changes presented as spinal cord cysts or syringomyelia. A classification of the detected changes by the types of injuries and their aftereffects is presented in the paper. The authors emphasize the desirability of MRT in spinal injuries with signs of cord dysfunction. PMID:7801568

    The clinicopathologic features of calcific myonecrosis are presented from results of an examination of 3 cases of this rare syndrome and review of the literature. Calcific myonecrosis is a painful, expansile, calcified mass that develops in muscle several decades after lower extremity trauma that typically has been associated with vascular injury. Plain radiographs show a well-defined and heavily calcified mass replacing the leg musculature. The calcifications are present in a thin, linear pattern and are organized around the periphery of the lesion. Smooth erosion of the adjacent bone may be present, whereas magnetic resonance imaging shows a heterogeneous signal with enhancement limited to the periphery of the mass. Pathologic features consist of a centrally cystic mass arising in muscle filled with friable, tan to dark red, soft debris. The cyst walls are firm and fibrous and contain many needle-like, elongated, calcified shards of necrotic tissue composed of hypocellular fibrous tissue with focal aggregates of hemosiderin-laden macrophages. The cyst contents are composed of necrotic skeletal muscle and acellular amorphous debris containing many cholesterol crystals, fibrin, and recent hemorrhage, including focal aggregates of organizing thrombus. The pathologic findings suggest that calcific myonecrosis might expand with time by virtue of recurrent intralesional hemorrhage into a chronic calcified mass that eventually becomes symptomatic. Surgical intervention is associated with a high rate of complication, particularly in cases in which intralesional procedures have been done. PMID:7671519
