Abstract

Post-ictal psychoses have so far received little attention. The clinical details of 14 cases, diagnosed according to newly formulated criteria, were examined. Psychoses were usually precipitated by a run of seizures and occurred after a lucid interval. The seizures were partial complex with secondary generalisation in 11 cases. Catego analysis of the Present State Examination confirmed pleomorphic phenomenology. Follow-up details were available in all cases, for up to eight years. Psychoses tended to recur. Similarities with chronic epileptic psychosis are discussed, and a possible organic aetiology for post-ictal psychosis is proposed.
