RESUMO

Introdução:

O declínio cognitivo relacionado à neurocisticercose (NC) ainda permanece mal caracterizado e pouco diagnosticado. Recentemente, nosso grupo mostrou que uma significativa parcela de pacientes com NC na fase cística ativa apresenta-se com declínio cognitivo e comprometimento funcional (Ciampi de Andrade et al., 2010). Não existem estudos controlados que avaliem essas alterações em pacientes com NC na fase calcificada na literatura até presente momento.

Objetivos:

Avaliar o desempenho cognitivo do maior subgrupo de NC, constituído de pacientes com NC na fase estritamente calcificada (C-NC). Verificar a presença de demência e comprometimento cognitivo sem demência (CCSD) nesses pacientes e tentar correlacionar os resultados obtidos a achados de neuroimagem. Investigar se existe presença de um espectro de anormalidade cognitiva na NC conforme a fase da doença. Metódos e Casuística Quarenta pacientes (média de idade = 37,6+ 11,3 anos e escolaridade média= 7,0+ 3,5 anos), com critérios diagnósticos absolutos de C-NC foram submetidos à avaliação cognitiva e funcional, sendo comparados a 40 pacientes controles saudáveis (CS) e 40 pacientes com NC ativa (A-NC), emparelhados por idade e nível educacional. Todos os pacientes do grupo C-NC foram submetidos a estudo de RM de encéfalo, a fim de excluir outras causas de epilepsia e sinais de atividade inflamatória.

Resultados:

Os doentes C-NC apresentaram uma média de 9,40 ± 3,13 testes alterados dos 30 da bateria de avaliação cognitiva quando comparados aos CS. Nenhum paciente C-NC mostrou critérios para demência e 10 (25%) tiveram critérios para CCSD. O grupo ANC tinha 5 pacientes (12,5%) com demência e 11 (27,5%) com CCSD. Mais de 50% dos doentes C-NC apresentaram desempenho inferior em memória verbal, atenção e função executiva em comparação aos CS. Não se encontrou correlação entre as alterações nos testes cognitivos nos pacientes C-NC e A-NC e os achados de neuroimagem e a frequência de crises...
ABSTRACT

Introduction:

Cognitive decline related to neurocysticercosis (NC) remains poorly characterized and underdiagnosed. We have previously shown that a significant proportion of active NC patients (A-NC) present cognitive and functional impairment. Until now, there is no control study that have evaluated cognitive abnormalities in patients in the calcified phase of NC.

Objective:

To evaluate the cognitive performance of the largest subgroup of NC, the strict calcified patients (C-NC). Check the presence of dementia and cognitive impairment no-dementia (CIND) and correlate the results with neuroimaging findings. To investigate whether there is a spectrum of cognitive abnormalities in the disease according to disease phase. Methods and

participants:

Forty treatment-naive patients with C-NC aged 37.6 ± 11.3 years and fulfilling absolute criteria for definitive C-NC were submitted to a comprehensive cognitive and functional evaluation and were compared with 40 active NC patients (A-NC) and 40 healthy controls (HC) matched for age and education. All patients of C-NC group underwent brain MRI study in order to exclude other causes of epilepsy and signs of inflammatory activity.

Results:

Patients with C-NC presented 9.4 ± 3.1 altered test scores out of the 30 from the cognitive battery when compared to HC. No C-NC patient had dementia and 10 patients (25%) presented CIND. The A-NCYST group had five patients (12.5%) with dementia and 11 patients (27.5%) with CIND. More than 50% of C-NC patients had low performance in verbal memory, attention and executive functions in comparison to CS. No significant correlation was found between cognitive performance and the number of lesions and seizure frequency. On follow-up, three out of five previously demented A-NCYST patients still presented cystic lesions with scolex on MRI and were still demented. One patient died and the remaining patient no longer fulfilled criteria for neither dementia nor CIND, presenting...
