STROKE-RELATED SEIZURES AND THE ROLE OF CORTICAL AND SUBCORTICAL STRUCTURES

Of 4,425 hospitalized patients with evidence of completed stroke, 217 (4.7%) had one or more epileptic seizures. in 187 of them, ischemic st roke involved the cortical (85, 45.5%) or subcortical(61, 32.6%) struc tures, or both (41; 21.9%); in 30 patients, the stroke was hemorrhagic and was lobar (67%), subcortical (20%), or massive (13%). Seizures or iginate from cortical dysfunction, but our data indicate that subcorti cal structures also play a significant role in the genesis of epilepti c seizures of vascular origin.
