EEG, sindromes epilépticasResumo
Desde a última classificação internacional das síndromes epilépticas, em 1989, foram descritos novos padrões eletrográficos e novas síndromes foram publicadas, deixando a atual classificação desatualizada. 0 EEG 0 fundamental para o diagnóstico diferencial dos espasmos infantis, sobretudo com a síndrome de West, pois, Wen' de identificar a forma benigna, muito contribuiu para a atual hipótese de sua fisiopatologia. A síndrome de Lennox-Gastaut pode ser diferenciada dos pseudos Lennox-Gastaut, graças ao EEG. Na epilepsia rolandica, o EEG identifica a forma primaria e, recentemente, foi sugerida mudança no seu conceito. A identificação de atividade epileptiforme focal frontal nas ausências e na epilepsia mioclOnica juvenil (epilepsias generalizadas primarias) tem levantado novas hipóteses fisiopatológicas. A epilepsia parcial benigna da infância com crises parciais complexas ou com generalização para convulsões recebeu essa denominação graças ao EEG iotal. Os aspectos morfológicos do EEG crítico e do dipolo intercritico, na epilepsia do lobo temporal, tam contribuído para a localização da zona epileptogénica.
