Complex epileptic palilalia: a case report.

Palilalia is a kind of motor perseveration involving speech, consisting in the continuous repetition of words or phrases, or both. Rarely it occurs in seizure disorders as ictal or post-ictal manifestation. We report a case of epileptic palilalia in a 71-year-old patient with a previous history of intracerebral haemorrhage in the left frontal region, characterized by the continuous repetition of the same speech sequence for few minutes. EEG recordings during NREM sleep and wakefulness showed recurrent and prolonged focal subclinical epileptiform paroxysms in the left mesial frontal region. Our case confirms the role of the left frontal lobe, reliably of the supplementary motor area (SMA), as neuroanatomic origin of ictal palilalia.
