The concept of ‘perisylvian epilepsy’ was originally introduced by Munari et al., in an attempt to distinguish this form of epilepsy from temporal lobe epilepsy proper. It should be noted, however, that in perisylvian the epileptogenic zone often encompasses the first temporal gyrus, accounting for the frequent presence of simple auditory hallucinations in this form of epilepsy, and explaining why the term ‘temporo-perisylvian’ is preferable to that of ‘perisylvian’. Apart from simple auditory hallucinations, temporo-perisylvian seizures are characterized by the presence of symptoms reflecting the involvement of the frontal and parietal operculum (hemifacial motor or somato-sensory symptoms, gustatory hallucinations, hypersalivation), the secondary somato-sensory area (various types of ipsilateral, contralateral or bilateral somatosensory symptoms), and the temporo-perisylvian vestibular cortex (vertigo).
