UNLABELLED To show the results of the exploration conducted with intracerebral electrodes in a patients affected by epileptic nocturnal wanderings (ENWs). METHOD The patient was investigated with long-term video-stereo-electroencephalographic (SEEG) monitoring by means of stereotactically introduced intracerebral electrodes. RESULTS We recorded four nocturnal seizures with typical features of ENWs. The SEEG ictal recordings demonstrated a well-localized initial discharge always confined to the right temporal structures with secondary spread to the cingulate regions. DISCUSSION Together with paroxysmal arousals and nocturnal paroxysmal dystonia, ENWs has been considered as a manifestation of the nocturnal frontal lobe epilepsy. Our investigation and the result of surgical outcome in this patient indicate that in some cases such episodes could have a temporal-lobe origin.
