Psychiatric aspects of epilepsy.

Patients who have epilepsy frequently have comorbid psychiatric disorders. Research into the relationship between seizures and psychiatric disorders has begun to reveal a complex relationship between neurobiology and behavior. This article reviews the diagnosis and treatment of mood disorders, psychotic disorders, and aggression in epilepsy. The psychopharmacology of anti-epileptic drugs and other psychotropics in epilepsy, including relevant information about drug—drug interactions, is summarized to assist with treatment decisions. Finally, a discussion of psychogenic seizures and epilepsy surgery reviews recent treatment recommendations.
