Epilepsy and psychotic disorders such as schizophrenia co-occur more often than would be expected by chance, and there are several syndromes - the "psychoses of epilepsy" - in which seizures and epilepsy are known to give rise to psychotic signs and symptoms (for a review see Trimble (1991)). Here, we describe a man with schizoaf-fective disorder and epilepsy whose case demonstrates a new type of epilepsy-related psychotic phenomena; highlights the complex interplay between neurology, psychiatry and pharmacology; and offers support for a "neural hypersensitivity" model of psychosis (Heinks-Maldonado et al., 2007).
