Abstract

Seizures are the most common neurologic manifestation in childhood. The demonstration of epileptiform disshonge on EEG not only support clinical diagnosis but also aid the classification of epilepsy. 174 patients with recurrent seizure were taken EEG studies in Chuncheon Sacred Heart Hospital from Jan. 1985 to Dec. 1990. and 71 patients (40.8%) of them occured epilepiform discharge in inital EEG recording. The incidence of epilepiform pattern in our study showed that centrotemporal spike was most frequent epileptiform discharge (29.6%) throughout the childhood and that localized spike (26.8%), Poly SW (8.5%), Atypical SW.(7.0%), Slow SW (7.0%), 3 Hz SW, MuS, hypsarrythmia, PFA occured in order of frequency. The incidence of epileptiform discharge at different age was observed that hypasrrythmia PFA and MuS occurred in mainly infancy and early childhood, fell rapidly with time, and that Poly SW and Slow SW occured through childhood, and that centrotemporal spike peaked school age and fell with the time, and that atypical SW and 3 Hz SW occured late childhood and peaked aldolescence. Localized spikes occured beyond infancy. The classification of epilepsy according to epileptiform discharge showed that partial epilepsy (57. 3%) was more frequently occured than generalized epilepsy, and that BRE was the most frequent epileptic syndrome in childhood.
