INTRODUÇÃO: A epilepsia é um distúrbio neurológico com crises recorrentes, promovendo o aumento do risco de desenvolvimento de desajustes psicossociais, restrições e prejuízos na qualidade de vida (QV) de crianças e seus familiares. OBJETIVOS: Avaliar a QV de crianças com epilepsia refratária ao tratamento medicamentoso e de seus cuidadores. MÉTODO: Estudo hipotético-dedutivo-observacional-transversal. Utilizou-se questionários de QV (AUQEI, WHOQOL-bref) e Escalas de Inteligência Wechsler (WAIS-III e WISC-III). RESULTADOS E CONCLUSÕES: A criança com epilepsia refratária tem QV prejudicada (média 47,25). Seu cuidador mostra satisfatória QV (média 83,41).
The study suggests that spatial orientation memory relies on the integrity of the right hippocampus. Nevertheless, further studies are necessary to confirm this hypothesis.
Objective: To identify tools available in literature for assessing the financial management capacity of elderly persons with and without cognitive deficit or impairment. Methods: An integrative literature review was performed. Scientific publications indexed in the PubMed, LILACS (Latin American and Caribbean Health Sciences Literature), Psychology Index and Cochrane Library databases by November 2015 were evaluated. Results: Of the 609 articles obtained from the databases, 29 were considered eligible for this review, and involved 11 instruments for the evaluation of financial management capacity, the most cited of which was the Financial Capacity Instrument (FCI). Conclusion: There are several scales and instruments available which are used to investigate both daily and instrumental activities of daily living, which allow the independence and effective functioning of the elderly on a day to day basis to be verified. Non-Brazilian literature also describes specific instruments for the assessment of financial management capacity. However, no references to a specific scale that evaluates this construct and which has been validated and adapted for the Brazilian population were identified.
RESUMOPassados mais de 50 anos, desde que Brenda Milner começou a avaliar pacientes com epilepsia refratária, os testes utilizados nos centros de cirurgia de epilepsia são praticamente os mesmos. Pouco progresso ocorreu em relação ao surgimento de novas técnicas e métodos mais sensíveis e específicos para este fim. Parece que alcançamos o máximo com as técnicas padrões que possuímos o que nos leva a concluir, que sem a inclusão de novas metodologias, a possibilidade de diagnósticos mais específicos e fidedignos, não será mais possível. Novos paradigmas precisam ser desenvolvidos, assim como técnicas que permitam o mapeamento de funções cognitivas, como a Ressonância Magnética funcional. Neste artigo, discutimos a investigação neuropsicológica de pacientes com epilepsia refratária e questionamos alguns aspectos da avaliação da linguagem e memória, bem como sua utilidade para predizer a extensão dos déficits de memória que poderão ocorrer após a cirurgia. Além disso, fazemos referência as novas perspectivas de investigação neste contexto. ABSTRACT News perspectives in epilepsy cirurgy neuropsychological evaluationMore than fifth years have passed since Brenda Milner has started the epilepsy surgery neuropsychological evaluation and tests in use nowadays are mostly the same, i.e., there was little if any progress in terms of the development of new and more sensitive or specific methods. We may have reached the maximum of diagnostic differentiation with standard neuropsychological tests, and without inclusion of experimental test condition, more elaborate diagnostics will not be possible. We have examined several issues relevant to the utility of the current evaluation and also, some alternatives to help making surgery more safe in relation to the cognitive functions. We discuss also, the development of new paradigms to activate cortical functions, like functional Magnetic Resonance. In this article, we discuss neuropsychological investigation of patients epilepsy surgery and whether the approach of memory and language evaluation used is useful in predicting the extent of memory deficits following epilepsy surgery. Moreover, we make reference the new perspectives of investigation in this context.
There are individuals who have a progressive language deficit without presenting cognitive deficits in other areas. One of the diseases related to this presentation is primary progressive aphasia (PPA). Objective: Identify by means of diffusion tensor imaging (DTI) and measurements of cortical volume, brain areas that lead to dysphasia when presenting signs of impaired connectivity or reduced volume. Method: Four patients with PPA were evaluated using DTI, and measurements of cortical volumes in temporal areas. These patients were compared with two normal volunteers. Results: There is a trend to a difference in the number and volume of related fibers between control group and patients with PPA. Comparing cortical volumes in temporal areas between groups yielded a trend to a smaller volume in PPA patients. Conclusion: Patients with PPA have a trend to impairment in cortical and subcortical levels regarding relevant areas.

Objetivo: Identificar, pela imagenologia, áreas cerebrais que quando sofrem atrofia, ou quando seu sistema de conexões apresenta alterações, levam a disfasia. Método: Foram avaliados quatro pacientes com APP, utilizando-se ressonância magnética com as técnicas de imagem por tensores da difusão (DTI) e medida do volume cortical em áreas de interesse previamente definidas. Estes pacientes foram comparados com um grupo controle constituído por dois voluntários. Resultados: Redução da média dos volumes dos giros temporais esquerdos no grupo de pacientes, em relação ao grupo controle, e alterações quanto ao volume e número de fibras nos tratos correspondentes. Conclusão: Pacientes com APP têm tendência a apresentar danos tanto ao nível cortical quanto subcortical.

OBJECTIVEThe purpose of the present study was to prospectively quantify the normal limits of brain perfusion using specific software in a group of asymptomatic young volunteers submitted to single-photon emission tomography (SPECT) with 99mTc-ethyl cysteinate dimer (99mTc-ECD).METHODSWe used 15 MBq/kg of intravenous 99mTc-ECD in 30 healthy volunteers submitted to brief neuropsychological tests and a clinical questionnaire. These data were normalized relative to the cerebellum (Group 1) and to the brain cortex (Group 2). Statistical analysis was performed with Student's t-test. The average radioactivity was 6.5 million counts/study.RESULTSThe normalized (Group I) revealed an average value of 78.03%, with standard deviation (SD) of 4.07. Two volunteers in this group had slightly greater than two standard deviations from the mean. When we used (Group II), the average value was 71.01%, with a SD of 4.66. We observed a difference between groups of 9% (P<0.001).CONCLUSIONThe present study suggests normal cortical perfusional values for a group of young asymptomatic volunteers, utilizing 99mTc-ECD. This allows further quantification of neuro-SPECT data, specifically comparisons across patient populations. Furthermore, this method represents a new tool that can be used to further explore the field of neuroimaging, particularly neuropsychiatry.
Psychogenic nonepileptic seizures (PNES) may be defined as paroxysmal changes in behavior that are similar to epileptic seizures but are not associated with quantifiable alterations in the electrical activity of the brain. At the Epilepsy Surgery Program (ESP) of the São Lucas Hospital at PUCRS (HSL-PUCRS), we studied 52 individuals (37 females and 15 males) with a diagnosis of PNES, associated (57%) or not (23%) with refractory epileptic seizures. We found emotional abuse (100%), physical abuse (80%), emotional neglect (80%), physical negligence (70%) and sexual abuse (30%), mood (40%) and anxiety disorders (50%), as the main psychological components in such population. Although the medical and psychosocial impact of PNES can be estimated as significant, the absence of specialized services for its treatment is striking. Multiple diagnostic and therapeutic procedures and the participation of a specialized multidisciplinary team -where neuropsychology functions as a link between the mental processes/psychopathologies and the brain -are required to ensure proper management of such cases.Key words: psychogenic nonepileptic seizures, neuropsychological evaluation. RESUMO Aspectos neuropsicológicos de crises não-epilépticas psicogênicasCrises não-epilépticas psicogênicas podem ser definidas como episódios de alterações paroxísticas no comportamento, similares a crises epilépticas, porém não associadas a alterações quantificáveis da atividade elétrica cerebral. No Programa de Cirurgia de Epilepsia do Hospital São Lucas da PUCRS estudamos 52 indivíduos (37 mulheres e 15 homens) com o diagnóstico de CNEP, associadas (57%) ou não (23%) a epilepsia refratária. Aspectos psicológicos nesta população incluíram abuso emocional (100%), abuso físico (80%), negligência física (70%), abuso sexual (30%), desordens de humor (40%) e ansiedade (50%). O impacto médico e psicossocial deste diagnóstico é elevado, fazendo contraponto a carência de serviços especializados em seu tratamento. Múltiplos procedimentos diagnósticos e terapêuticos e a participação de um time multiprofissional -onde a neuropsicologia representa o elo natural entre a psicopatologia e o cérebro -são necessários para o melhor atendimento a estes pacientes.
