Clinical and EEG Findings in Eleven Patients with Insular Epilepsies

Purpose: We have attempted to study auras, seizure semiology, and EEG findings in insular epilepsies. Methods: We reviewed the clinical and EEG data of eleven patients with epileptogenic lesions in the insular region. Ten patients underwent EEG-video intensive monitoring with surface electrodes and three patients subsequently underwent invasive EEG recording with subdural grid electrodes. One outpatient had only a routine EEG taken. Clinical data of two patients were excluded: One patient was too handicapped to report auras reliably. The other patient had an additional large extrainsular lesion making it unclear…
