✓ The purpose of this investigation was to determine the short-term behavioral and emotional effects of anterior temporal lobectomy (ATL). Forty-one patients who underwent ATL were administered a standardized measure of emotional adjustment (Mental Health Inventory) on four occasions: preoperatively, and 1,3, and 6 months postoperatively.
