Objetivo: Describir las características neuropsicológicas de pacientes con demencia frontotemporal varianteconductual (DFTvc) y compararlas con las de pacientes con enfermedad de Alzheimer (EA). Pacientes y métodos:Se evaluó una muestra de 60 controles sanos, 60 pacientes con EA y 32 pacientes con DFTvc, empleando una bateríaneuropsicológica clásica. Resultados: Los pacientes con DFTvc tienen peor rendimiento que pacientes con EA enalgunos parámetros de atención y funciones ejecutivas (FE) y menor compromiso de la memoria. La evaluaciónde atención muestra diferencia altamente significativa en el rendimiento del Trail Making Test (TMT)-A entre EAy DFTvc (t28=-2,18, p<0,001). De la misma manera, en la evaluación de FE, sólo el TMT-B (t31= -6,8, p<0,001) ylas respuestas perseverativas en el Wisconsin Card Sorting Test (WCST) (U = 30,5, p<0,001) alcanzaron diferenciaestadísticamente significativa entre los grupos EA y DFTvc. Conclusiones: Los pacientes con DFTvc en estadiosleve a moderado presentan una relativa menor afectación de memoria, lenguaje y habilidades viso-constructivas/viso-espaciales, pero con un marcado deterioro de atención y FE.

Neste trabalho, tentamos identificar índices de simulação na avaliação neuropsicológica forense, através da avaliação dos padrões de resposta em provas neuropsicológicas. A amostra foi constituída por 56 sujeitos com traumatismo crânioencefálico. Todos se encontravam numa situação de possível recompensa monetária por incapacidade. Utilizamos os instrumentos Wisconsin Card Sorting Test (WCST), Trail Making Test (TMT), Inventário de Sintomas Psicopatológicos (BSI), e a grelha de análise dos autos do processo. Cerca de 30% da amostra enquadrou-se no grupo de prováveis simuladores. Essa porcentagem é congruente com a literatura. Verificou-se uma grande homogeneidade entre os indivíduos com e sem indicadores de simulação, a nível sintomatológico e características sócio-demográficas, o que reforça a necessidade de desenvolvimento de métodos eficazes na detecção da simulação.

Background: Schizophrenia is severe disorders and imposes a considerable burden on patients, their families and society. Schizophrenia tends to run in family, like most mental disorder shows complex inheritance. Therefore, it is important to increase our knowledge about the disorder. Cognitive dysfunction is one of the core features of Schizophrenia. This study aims to compare the cognitive function of first degree unaffected relative of patient of schizophrenia and a group of healthy control.Methods: The study include 48 first degree normative relative of patient with Schizophrenia and 48 controls. Compared for age, sex, education level. Cognitive functions of each case and control were assessed using TMT (Trail making Test), Paced auditory serial addition Test (PASAT) and Wisconsin card sorting test (WCST-64).Results: First degree relative performed significantly poorly as compared to controls on Wisconsin card sorting Test-64 (WCST-64). No significant difference was observed in tests performances between first degree relative of Schizophrenia and control group for TMT (trail making test) and Paced auditory serial addition Test (PASAT).Conclusions: The study shows possibility of cognitive impairment in first degree normative relative of Schizophrenia with regards to parameters like poor performance in shifting cognitive sets and poor understanding of test. Nevertheless, it is not clear weather this finding is an enduring trait mark or finding that fluctuates with sample size, nature of case and control.

Abstract Background In Oman, anecdotal and impressionistic observation have helped parse and categorize various manifestations of spirit possession into two broad and distinct categories: intermittent dissociative phenomenon and transitory dissociative phenomenon. The primary aim of the present study was to compare the performance of participants on neuropsychological tests among different grades of possession. Other correlates were also sought. Methods Assessment criteria for the two groups included measures examining executive functioning: controlled oral word association test Verbal Fluency, Wisconsin Card Sorting Test (Perseverative error and the number of categories achieved), Trail Making Test and the Tower of London Test (number of correctly solved problems). Sociodemographic variables and the history of trauma were also sought. Result Among 84 participants, one third of them presented the intermittent possession type and two thirds, the transitory possession type. Their mean age was 34.17 ± 11.82 and 56% of them were female. Nearly 35% of them endorsed a history of a traumatic experience. Both the multivariate models showed statistical significance (F (5, 78) = 5.57, p < 0.001, R2 = 0.22), F (5, 78) = 11.38, p < 0.001, R2 = 0.39) with an independent predictor of intermittent dissociative phenomenon (β = − 3.408, p < 0.001), (β = 63.88, p < 0.001) for Verbal Fluency and Trail Making Test, respectively. The history of the traumatic event was also statistically significant with the results of the Trail Making Test (β = − 26.01, p < 0.041. Furthermore, the subtype of Pathogenic Possession turned out to be an independent predictor across all models: Wisconsin Card Sorting Test perseverative error, Wisconsin card sorting test categories achieved and the number of problems solved in the Tower of London Test (OR = 3.70, 95% C.I. 2.97–4.61; p < 0.001), (OR = 0.57, 95% C.I.0.39–0.84; p = 0.004) and (OR = 0.80, 95% C.I. 0.65–0.99; p < 0.037) respectively. Conclusions This study suggests that typology of spirit possession found in Oman tends to differ on indices of executive function. Those with ‘diagnosis’ of intermittent possession showed impairment in many indices of executive functioning. Despite its wide prevalence, spirit possession has not been examined in terms of its neuropsychological functioning. We believe that this study will be instrumental in laying the groundwork for a more robust methodology.

Este estudo comparou e relacionou o desempenho de idosos com Comprometimento Cognitivo Leve e Demência Tipo Alzheimer em testes de controle executivo e de memória episódica verbal. Para a avaliação da memória episódica verbal utilizamos a Tarefa de Recordação de Palavras Imediata e a Tarefa de Recordação de Palavras com Intervalo. Na avaliação do controle executivo foram utilizados, os seguintes testes: Random Number Generation, Trail Making Test, Fluência Verbal semântica e fonológica, Wisconsin Card Sorting Test, Reading Span Test e Brow-Peterson Test. Treze idosos do grupo controle foram equiparados quanto à idade e escolaridade com nove idosos com Comprometimento Cognitivo Leve e oito idosos com Demência Tipo Alzheimer. Foram encontradas diferenças e associações estatisticamente significantes em relação aos testes de controle executivo entre os grupos investigados. Apesar da presença de associações significativas entre a memória episódica verbal e o controle executivo, não foram evidenciados déficits do controle executivo nos idosos com Comprometimento Cognitivo Leve.

A cluster analytic solution based upon a battery of tests consisting of the Halstead Category and Tactual Performance Tests, the Trail Making Test, and the Wisconsin Card Sorting Test was compared with a solution based on the subtests of the Wechsler intelligence scales, utilizing a sample of 221 schizophrenic patients. Both analyses permitted four-cluster solutions, and we found a weak but significant degree of association between solutions. Examination of external validity of the two solutions revealed stronger associations with clinical variables for the Wechsler-scale-based solution. The major conclusions were that the existence of cognitive heterogeneity in schizophrenia exists across a broad range of abilities, and appears to reflect a combination of continuity of ability level and existence of possible subtypes requiring further neuropsychological and neurobiological verification.

Introdução: O funcionamento executivo preservado para a manutenção de comportamentos adaptativos é condição necessária para obtenção de desfechos clínicos favoráveis no tratamento de sujeitos em dependência química. A confirmação da hipótese de disfunção executiva pode fornecer subsídios ao tratamento comportamental, do sujeito com dependência química. Objetivo: O estudo consistiu na realização de uma avaliação neuropsicológica das funções executivas de mulheres dependentes químicas de cocaína ou crack. Método: A avaliação se deu através de anamnese/exame clínico, entrevistas e testes neuropsicológicos. Para a caracterização da amostra foi utilizado o Protocolo de Anamnese Neuropsicológica. A avaliação neuropsicológica das funções executivas consistiu da aplicação do Wisconsin Card Sorting Test (WCST), Subteste Dígitos - Wechsler Adult Intelligence Scale (WAIS-III), Blocos de Corsi, Trail Making Test (TMT), Stroop Test e o Montreal Cognitive Assessment (MoCA), a fim de investigar oito componentes executivos, a saber: memória operacional, flexibilidade cognitiva, categorização, fluência verbal, atenção seletiva e alternada, rastreamento visuomotor e controle inibitório. Resultados: Os resultados permitiram concluir que mulheres com dependência química, pelo uso de cocaína e <em>crack,</em>apresentam disfunção executiva. Foram encontradas relações clinicamente significativas entre tempo de uso e déficits do funcionamento executivo, indicando que quanto maior o tempo de dependência, mais expressiva a disfunção executiva.<p><strong>Descritores:</strong><strong> </strong>Função Executiva; Neuropsicologia; Transtornos Relacionados ao Uso de Substâncias.</p>

Background:Obesity is a chronic condition associated with poorer cognitive functioning. Wisconsin Card Sorting Test (WCST) is a useful tool for evaluating executive functions. In this study, we assessed the association between dopaminergic gene polymorphisms: DAT1 (SLC6A3), COMTVal158Met, DRD4 (48-bp variable number of tandem repeats - VNTR) and WCST parameters to investigate the functions of the frontal lobes in obese individuals.Objective:To find the significant correlations between polymorphisms of DAT1, COMTVal158Met, DRD4 and executive functions in obese subjects.Methods:The analysis of the frequency of individual alleles was performed in 248 obese patients (179 women, 69 men). Evaluation of the prefrontal cortex function (operating memory and executive functions) was measured with the Wisconsin Card Sorting Test (WCST). Separate analyzes were performed in age subgroups to determine different activities and regulation of genes in younger and older participants.Results:Scores of WCST parameters were different in the subgroups of women and men and in the age subgroups. Regarding the COMT gene, patients with A/A and G/A polymorphisms showed significantly better WCST results in WCST_P, WCST_CC and WCST_1st. Regarding DAT1 men with L/L and L/S made less non-perseverative errors, which was statistically significant. In DRD4, significantly better WCST_1st results were found only in older women with S allele.Conclusion:Obtained results indicate the involvement of dopaminergic transmission in the regulation of prefrontal cortex function. Data analysis indicates that prefrontal cortex function may ensue, from different elements such as genetic factors, metabolic aspects of obesity, and hormonal activity (estrogen).
