Risk of seizure recurrence after a first unprovoked seizure: a prospective study among Jordanian children.
OBJECTIVE
There is wide variation in the reported recurrence rate after a first unprovoked seizure in children. We investigated the risk of recurrence after a first unprovoked seizure in Jordanian children and the risk factors associated with increased recurrence rate.


METHODS
All consecutive patients aged 3 months-14 years who presented with their first unprovoked seizures between January 1997 and 2000, were included in a prospective study and followed up for 3 years for possible recurrence. Of the patients studied, there was slight male predominance (56.6%) and 55% of them were 2-9 years of age. Generalised seizures were reported in 75% and the remaining 25% had partial seizures. The duration of seizure was 1-4 minutes in 59%. Family history of epilepsy was positive in 31% and parental consanguinity in 32%. The role of these factors in increasing the risk of recurrence was also investigated.


RESULTS
Two hundred sixty-five patients were included in the study and continued follow up for 3 years. Ninety-eight (37%) of them experienced seizure recurrence. Among the predictor factors for recurrence, partial seizure (P = 0.003) and positive family history (P = 0.000) were associated with a statistically significant increased risk. Sex, age, duration of seizure and consanguinity were not associated with increased risk of recurrence.


CONCLUSIONS
Thirty-seven percent of the children studied experienced a second attack after a first unprovoked seizure over the 3 years follows up period. The risk of recurrence was significantly higher in children with a partial seizure (55%) and among those with a positive family history of epilepsy (59%). Age at first seizure, sex, duration of seizure and consanguinity were not significantly related to the risk of recurrence.
