See this aricle in Pubmed

Article Abstract
We followed 208 patients identified on the day of their 1st unprovoked seizure for a mean duration of 4 years.Seizures recurred in 64.Recurrence risks were estimated to be 14%,29%,and 34%at 1,3,and 5 years following the 1st episode.A history of previous neurologic insult(remote symptomatic)was associated with a 2.5-fold increased risk of recurrence.Among idiopathic cases,a sibling with epilepsy,a generalized spike and wave EEG,or a history of acute symptomatic seizure increased risk for recurrence.Among remote symptomatic cases,status epilepticus,a prior acute symptomatic seizure,or Todd's paresis increased risk.Depending upon clinical features, recurrence risk at 5 years following a 1st seizure ranged from 23%to 80%. Treatment with anticonvulsant medication was not associated with a decrease in recurrence risks.
