The purpose of our study was to describe electroclinical features of auditory aura and to find a possible lateralizing value in partial epilepsy. 123 epileptic patients with auditory features over 8000 were enrolled; according to the dominant type of aura, they were divided into four subgroups: simple or complex hallucinations, positive or negative illusions. Comparing the side of auditory symptoms, EEG and neuroradiological findings, ictal lateralizing signs as aphasia, we suggest that the side of aura is scarcely useful in the lateralization of epileptic focus. Complex hallucinations with musical content seem more probably refer to non-dominant, those with verbal content to dominant hemisphere. Negative illusion may be more frequent in dominant hemisphere foci. We confirm that auditory aura is a rare symptom in partial epilepsy.
