Abstract

This is a comparative video-electroencephalographic (EEG) study of typical absence seizures in 4 epileptic syndromes. In 20 patients, 224 absences were recorded and analysed. Significant clinical and EEG differences were found in the seizure patterns of childhood absence epilepsy (CAE), juvenile absence epilepsy (JAE), juvenile myoclonic epilepsy with absences (JMEA) and myoclonic absence epilepsy (MAE). Clinically, CAE demonstrated more severe impairment of consciousness than JAE while, in JMEA, ictal manifestations were frequently mild and difficult to detect. In the latter, the adolescent patient usually continued his activity, was able to perform even mathematical calculations and often his speech was not disturbed. In children with JMEA, impairment of consciousness was more apparent and sometimes severe. Automatisms occurred in all 4 epileptic syndromes and were proportional to the severity of the demonstrated impairment of consciousness, being rare in JMEA but frequent in CAE and JAE. Expressive speech and overbreathing usually persisted for 1-2 s after the onset of the EEG ictal discharge in CAE. It was less disturbed in JAE where in some absence seizures, interrupted speech and overbreathing were restored during the ict...Continue Reading
