Early seizures caused by stroke are a common cause of epilepsy in adults. The protocol for treatment in such a case is not clear. Patients were studied retrospectively after early poststroke seizures. Two groups of patients were compared: one treated group included 35 patients who continued therapy for 2 years; the second group of 23 patients were untreated following a first attack, receiving anticonvulsive therapy only after a second seizure. The data of 61 patients (35 treated and 26 untreated) were analyzed. In the treated group, 24 patients were on treatment with carbamazepine, 9 with valproic acid and 2 with phenytoin. Seizure-free rate after 2 years was 85% in group I and 61% in group II (p = 0.042). Comparing the seizure rate and the event-free period (number/follow-up at risk) during the 2 years of no anticonvulsive therapy, both groups experienced about the same seizure rate (4.8 vs. 6.2%, p = 0.605) and similar seizure-free curve survival analysis (p = 0.85). We conclude that treatment of seizures immediately after the first attack after cerebral infarctions decreases the risk of recurrent seizure during the first 2 years of antiepileptic treatment. This subgroup of patients receiving antiepileptic medication immediately after the first poststroke seizure continues to be at the same rate of risk after treatment was stopped as the untreated group during the first 2 years. Antiepileptic therapy is an option in the medical management of poststroke seizure patients, but has no influence on the development of recurrent seizures after discontinuing medication.
