ABSTRACT
Frequency of common etiologies of adult onset epilepsy is different in various studies. The aim of this study is to evaluate the frequency of common ‎etiologies of late adult onset epilepsies. ‎ All patients referred to Razi and Imam Khomeini Hospitals ‎in the year 2003 with at least two seizure attacks beginning after age of 50 were evaluated. In the majority of cases neuroimaging, electroencephalography and ‎echocardiography were done and risk factors for atherosclerosis and cerebrovascular ‎diseases were investigated. All medical records and previous medical histories ‎were reviewed. ‎A total of 97 patients were included. We found hemorrhagic stroke in 10 (10.3%), ‎ischemic stroke in 43 (44.3%) and space-occupying lesion (all of them were ‎tumors) in 19 patients (19.6%). In 24 (24.7%) cases we could not find a clear ‎cause for seizure attacks. ‎In conclusion, since seizures were associated with a central nervous system ‎disease in about 75% of the patients, careful investigation is necessary. We ‎also recommend better control of risk factors for cerebrovascular diseases in our country.
