An origin of epileptic seizures on the sample of 100 patients with SAH, treated at the Neurological Clinic from 1981-1993, was followed. The haemorrhage was shown by CT and/or cerebrospinal fluid. The sample consisted of 45 men and 55 women. Among the patients under 30 years of age men and over 30 women were predominant. Arterial hypertension was present in 17 cases. A positive angiographical finding of cerebrovascular malformation or aneurysm was ascertained in 38 cases. In 5 cases an early epileptic seizures with generalized convulsions occurred. Three women i.e. 3% of the sample, had late epileptic seizures occurring from 1 month to 5 years after SAH. The percentage of epileptic seizures described elsewhere is higher.
