Abstract

In epilepsy various psychiatric symptoms occur, such as neurotic symptoms，mood disorder-like symptoms, and schizophrenia-like symptoms. The incidence of psychotic symptoms among epileptic patients is significantly higher than among the general population. Sengoku et al. reported the incidence of psychosis among epileptic patients to be 4.4％. Psychotic disorders associated with epilepsy are divided into three groups: ictal psychosis, periictal psychosis, and interictal psychosis. Altemative psychosis and postictal psychosis are classified as acute periictal and interictal psychosis. We report a case of postictal psychosis and discuss the psychotic state, comparlng it with that of alternative psychosis. This postictal psychosis exhibited various features different from those of altemative psychosis, and many features of these symptoms are similar to those described in other reports. Many studies suggest that postictal psychoses and altemative psychoses have different features from case to case. Postictal psychoses often exhibit abnormally elevated mood and few schizophrenia-like symptoms such as Schneider's first-rank symptoms, whereas alternative psychoses often do exhibit Schneider's first-rank symptoms. This case showed typical features of postictal psychosis.
