Stroke is one of the most frequent causes of acute symptomatic status epilepticus. The aim of this study was to investigate the electroclinical features of status epilepticus in acute ischemic stroke. Nine consecutively admitted patients with status epilepticus during ischemic stroke were examined: five of them had convulsive unilateral or generalized status epilepticus for from 24 hours to 9 days after a large hemispheric infarction, always associated with EEG epileptiform abnormalities; the remaining four had focal motor status epilepticus during the first 24 hours after a small cortical or subcortical infarction, and showed no clear EEG changes. Status epilepticus in acute ischemic stroke may have two distinct electroclinical patterns of different prognostic significance.
