THERE have been few studies of the incidence and prognosis of seizures in patients with nonembolic cerebral infarction. Jackson in 18641 was amongst the first to comment upon a relationship between seizures and vascular disease, particularly embolic cerebrovascular occlusion, but he had no pathological confirmation of his diagnosis. Gowers in 18812 collected and reported 66 patients with "hemiplegia" and epilepsy, in some of whom the hemiplegia was thought to have resulted from embolic cerebrovascular occlusion. Two thirds of his patients were less than 5 years of age, and pathological confirmation of the specific cause of "hemiplegia" was not obtained. Dunham in 19163 reported seven patients with epileptic seizures found in a group of 100 patients consecutively admitted because of cerebrovascular accidents. The group was composed of patients with cerebrovascular disease of all sorts, and the fact that four of the seven epileptics also had syphilis
