ABSTRACT

Foram selecionadas 20 crianças com diagnóstico de epilepsia benigna da infância com pontas centrotemporais. Realizou-se anamnese, exame neurológico, aplicação da Escala de Maturidade Mental'' Columbia'' (1993) e eletrencefalograma digital. (EEG) O EEG digital foi gravado com eletrodos de acordo com o sistema internacional 10-20, acrescido de um eletrodo suplementar entre o eletrodos C3 eT3 ou C4 e T4 no lado onde ocorreu o maior número de pontas. Foi realizada a promediação dessas descargas para análise do local de máxima negatividade. A ocorrência de crises envolvendo um membro superior foi proporcionalmente maior nos sujeitos com pontas de máxima negatividade em C3, C4 do que em C5, C6, T3 ou T4. A atividade epileptiforme não centrotemporal associada foi mais frequente nos sujeitos com descargas centrotemporais de máxima negatividade em C3 e C4. Esse estudo demonstra a existência de diferenças clínicas e eletrencefalográficas de acordo com a localização das descargas centrotemporais

ABSTRACT

Twenty children with benign childhood epilepsy with centrotemporal spikes were studied. Anamnesis, neurological exam, "Columbia" Scale (1993) application and digital electroencephalogram were carried out. The digital electroencephalogram was recorded with electrodes according to 10-20 international system, and a supplementary electrode, between C3 and T3 or C4 and T4-C5 or C6, respectively, at the side with a higher number of spikes. The averaging of the spikes was carried. Localization and the laterality of the spikes were analyzed. Seizures involving a superior limb occurred in a higher proportion of cases with spikes of maximum negativity in C3, C4. Independent epileptiform activity, different from centrotemporal, was more frequent in the cases were the maximum negativity of the spikes occurred in C3 or C4 regions. There are clinical and electroencephalographic differences according to the localization of the discharges
