Postictal psychosis after temporal lobectomy

Abstract

Three of 282 consecutive patients who had temporal resections for intractable epilepsy developed postoperative postictal psychosis. These three patients had seizure recurrence contralateral to the resection, whereas none of the patients with ipsilateral seizure recurrence developed any psychiatric symptoms after surgery. Two had left amygdalo-hippocampectomy and one right temporal lobectomy. The de novo occurrence of postoperative postictal psychosis is a well-defined complication of surgery for temporal lobe epilepsy, and may relate to contralateral epileptogenesis.
