Abstract

To evaluate the risk of relapse in children with epilepsy whose anticonvulsant therapy has been withdrawn after prolonged control, we studied 148 such children for 15 to 23 years or until relapse. Forty-one of the 148 patients (28 per cent) had recurrence of seizures; of these, 35 (85 per cent) had relapses within five years of drug withdrawal. Factors associated with an increased risk of relapse were a long duration of epilepsy before control, neurologic dysfunction, and jacksonian seizures or combinations of seizure types. We found no association between risk of recurrence and age at onset of epilepsy, total number of seizures before control, age at discontinuation of therapy, electroencephalographic abnormalities, or family history of epilepsy. We conclude that children who do not have the additional risk factors noted above have an excellent chance of remaining seizure free after the withdrawal of anticonvulsant drugs.
