Abstract
Three hundred eight patients with childhood and adolescent epilepsy were examined to clarify the incidence of epileptic discharges on initial and follow-up electroencephalograms. Epileptic discharges were found in 75.6% patients on the initial electroencephalogram, which is higher than figures previously reported for adults. The cumulative incidence of epileptic discharges was 92.3% by the third electroencaphalogram recording. However, in 17.1% patients with nonspecific idiopathic generalized epilepsy, no epileptic discharges were found even after three electroencaphalogram recordings. The incidence of epileptic discharges in patients with generalized epilepsy (84.3%) was significantly higher than in patients with localization-related epilepsy (71.6%). The incidence of epileptic discharges in patients with partial seizures was lower than those in patients with generalized seizures. The incidence of epileptic discharges was low in the 0- to 3-year-old and 15- to 20-year-old groups, and high in the 3- to 12-year-old groups. In the positive epileptic discharge patients, 38.8% of electroencephalograms were abnormal only during the waking or sleeping portion of the recordings. Knowing the incidence of epileptic discharges for each type of epilepsy will be useful in planning further electroencephalogram research and performing electroencephalograms in the clinical setting.
