Antiepileptic drugs in aneurysmal subarachnoid hemorrhage

Abstract

Seizures may occur during or soon after rupture of an intracranial aneurysm. The use of antiepileptic drugs (AEDs) is a controversial issue. The overall conclusions from 2 recent studies in aneurysmal subarachnoid hemorrhage are that 1) many patients receive AEDs but should not; 2) long-term use is associated with worse outcome; and 3) short-term use is safer. Phenytoin may not be the first choice for seizure prophylaxis; newer AEDs such as levetiracetam might be more helpful in prevention and treatment of seizures.
