Foram estudadas, do ponto de vista eletrencefalográfico, 20 crianças que apresentaram crise convulsiva única, com intuito de verificar se nessas condições já ocorrem alterações que possam estar relacionadas com processos orgânicos encefálicos. Considerado de maneira global, o EEG mostrou-se alterado em 13 casos (65%) e foi normal em 7 (35%); as alterações foram do tipo focal em 12 casos e difusas em um. Os eletrencefalogramas com rítmo de base irregular e disritmia paroxística registrada durante a ativação pela hiperpnéia (8 casos ou 40%) corresponderam aos pacientes que, ulteriormente, apresentaram recorrência da convulsão.


The authors studied the EEG of 20 children with history of a single epileptic seizure, in order to establish a presumptive pathological factor in the central nervous system. In this series, 13 patients (65%) had abnormal tracings, and 7 (35%) had normal EEG records. The most frequent abnormality found was a focal change, recorded in 12 patients, while the diffuse type was found in just one. Abnormal tracings, either at rest or during overventilation, were most frequently seen in 8 patients which had recurrent seizures, registered in a three years follow-up.
