Investigation of poststroke epilepsy (INPOSE) study: a multicenter prospective study for prediction of poststroke epilepsy.

Poststroke epilepsy occurs in almost 6% of patients within 3 years after stroke onset. Hemorrhagic stroke and subcortical lesion appear to be significantly associated with likelihood of developing epilepsy. Thus, prophylactic administration of antiepileptic drugs could be useful for stroke patients with these two risk factors.
