Abstract
Epilepsy is associated with interictal behavioral disturbances. The pattern of specific psychopathology differs from that of other chronic diseases because of the higher incidence of psychosis and characterological disorders. Approximately 7 percent of epileptics develop a chronic atypical psychosis with paranoid and affective features, and this may be more common in patients with a definite temporal lobe focus. Brief psychotic episodes occur and are more directly related to cerebral dysrhythmia. A subgroup of epileptics develop specific personality traits, aggressive behaviors under certain circumstances, and hyposexuality. Affective illness and suicide are also prevalent. There are special issues in the management of psychopathology in the setting of epilepsy such as the relative seizure threshold lowering effects of psychotropic drugs and the behavioral effects of altering the seizure control. This article discusses both diagnostic and management aspects of the interictal psychopathology of epilepsy.
