FEBRILE SEIZURES - RATE AND RISK-FACTORS OF RECURRENCE

The rate of recurrence of febrile seizures and the factors predictive of a recurrence were prospectively examined in a cohort of 98 Saudi ch ildren who presented consecutively with their first febrile seizure at the pediatric emergency department of the King Khalid University Hosp ital, Riyadh, Saudi Arabia. Children with prior afebrile seizures or e vidence of a neurodevelopmental deficit were excluded. The median age was 15 months (range, 4 to 60 months). Of the 98 children, 72 had simp le and 26 had complex initial febrile seizures. In a follow-up of 3 to 6 years (mean, 49 months), 26% of the 98 untreated children had at le ast one recurrence and only 8% had more than three recurrent febrile s eizures; 30% of first recurrences took place within 3 months, 60% with in 6 months, 72% within 12 months, and 96% within 24 months of the ons et. Four major risk factors for recurrent febrile seizures were identi fied: early age at onset (< 12 months), first-degree consanguinity of parents, epilepsy in a first-degree relative, and complex initial febr ile seizure. Gender, family history of febrile seizures, and degree of fever were not related to recurrence.
