Electroencephalogram Abnormalities on Unprovoked First Seizure in Children with Normal Development Are Not a Risk Factor for Recurrence

抄録

The purpose of this study was to retrospectively investigate the utility of electroencephalography (EEG) for estimating the recurrence rate of seizures in pediatric patients with normal development who experienced an unprovoked first seizure. Subjects included 100 children aged 0 to 15 years with normal development who underwent an EEG for suspected first seizure between December 1, 2012 and December 31, 2016. Among the 100 subjects, 61 showed EEG abnormalities, and seizures recurred in 43 of them. Normal brain waves were observed in 39 subjects, among whom seizures recurred in 23. No statistically significant difference was found in EEG abnormalities or the rate of seizure recurrence between the groups. The EEG did not appear to be a useful tool for prediction of the possible recurrence of epileptic seizures in the future in this patient population.
