Risk of seizure recurrence following a first unprovoked seizure in children

Abstract

The aim of the study was to determine seizure recurrence rate and risk factors of a first unprovoked seizure in children. Ninety-one children aged 2 months-15 years who had a first unprovoked seizure were enrolled and followed-up. History and physical examination were undertaken. The results were displayed as a Kaplan-Meier survival curve. Multivariate analysis was performed with Cox proportional-hazards model. The cumulative probability of recurrence rate was 68 per cent and incidence density was 6.85 per 100 person-months. The cumulative risk of recurrence was 50 per cent at 4 months and 66 per cent at 12 months. No risk of seizure recurrence was found in this study.
