Clinicians must consider the psychiatric issues relevant to patients undergoing neurosurgical procedures for epilepsy. Obtaining the patient's psychiatric history can facilitate stabilizing the patient's condition before operative intervention. Preoperatively, depressive and anxiety disorders are the most common psychiatric conditions diagnosed in candidates for surgical treatment of epilepsy. Although psychotic disorders occur infrequently, they demand attention because symptoms may interfere with patient compliance with follow-up care. Patients with chronic psy-chotic symptoms who have ongoing seizures postoperatively and bilateral seizure foci are at higher risk for a poor outcome and postoperative psychosis. When psychiatric disorders are present, surgical management is not contraindicated, but preoperative psychiatric intervention may be warranted. Most patients have a favorable outcome with the elimination of seizures, which simplifies the subsequent treatment of a psychiatric disorder.
