Reversibility by Temporal-Lobe Resection of the Behavioral Abnormalities of Temporal-Lobe Epilepsy

Abstract

Aggression and psychosis were frequent preoperative complications in over 250 patients with temporal-lobe epilepsy who underwent unilateral temporal lobectomy. Pathological findings in the resected specimens, which included the hippocampus and the lateral amygdala, were mesial temporal sclerosis in about 1/2, hamartomas in 1/4, miscellaneous lesions such as scars and infarcts in 1/10, and nonspecific lesions in the remainder.
