The most frequent reason of seizures in elderly are vascular diseases of the brain. The early-onset seizures occur in first 7 days after stroke, and the late-onset seizures occur after 7 days after stroke. The aim of the study was to estimate the frequency of seizures in patients who have taken a stand in acute period of stroke, the incidence of seizures in different types of stroke, the frequency of the types of seizures and the risk of death depending on the type of seizure. One hundred and sixty seven patients with ischemic stroke and seizures were enrolled in this retrospective study. Patients have been divided into 2 groups: group I-with early-onset seizures and group II- with late-onset seizures. In our study seizure was the first symptom of acute stroke in 2.4% of ischemic stroke and 3.2% among patients with cerebral hemorrhage. Seizures occurred in 3.9% of patients with PACI stroke. The primary tonic-clonic generalised seizures occurred in 46.7% patients with early-onset seizures. In the group with early-onset seizures the mortality was 13.3%. In the group of poststroke epilepsy the mean time from stroke to seizure was 21 month. The early-onset seizures occurred in 2.5% patients with acute stroke. The early-onset seizures are most related to PACI stroke and cerebral hemorrhages. The primary tonic-clonic generalised seizures are most common in both groups. The highest mortality among early-onset seizures is related to primary tonic-clonic generalized and focal complex seizures.
