[Borderline infarcts with symptomatic epilepsy--clinical and electroencephalographic findings]

In 6 patients with repeating seizures early after stroke periodic lateralizing epileptiform discharges were detected in EEG. Computed tomography scans showed border-zone infarctions including the territories of the middle and the posterior cerebral artery in four patients; sonographic and angiographic findings were suspicious of embolic stroke in five cases. Seizures and EEG-discharges resolved during a short term treatment with anticonvulsants. In contrast to cerebral infarctions of other regions with comparable EEG-changes long term treatment was necessary in none of the patients.
