The aim of this study was to find out any abnormality of SEPs in focal epilepsies due to a cerebral lesion. The aim was also to define the relationships between abnormal SEPs and the electro-clinical and neuroradiological features of these patients. Fourty patients entered the study and underwent short and long latency SEPs. All patients had a diagnosis of symptomatic partial epilepsy with a well documented lesion on CT scan (usually focal atrophy, porencephaly, cysts, asymmetrical ventricular enlargement). SEPs were abnormal in all patients with a lesion located near to the postrolandic central regions. In these case, short latency SEPs could be normal but long latency components were invariably abnormal. Moreover, the degree of SEPs abnormality was strictly related to the degree of neurological involvement. We conclude that SEPs (mostly the long-latency components) may well correlate with the site of cerebral lesion and the degree of neurological involvement in symptomatic focal epilepsies.
