Relationship between presurgical memory performance on the Wechsler Memory Scale-III and memory change following temporal resection for treatment of intractable epilepsy.

Previous research demonstrated a relationship between preoperative memory measured by the Wechsler Memory Scale-Revised (WMS-R) and postsurgical memory change in patients who underwent left (LATL), but not right (RATL) anterior temporal lobectomy. The current study replicated previous efforts using the Wechsler Memory Scale-Third Edition (WMS-III) in a larger sample. The WMS-III was administered to 161 patients with medically intractable epilepsy prior to and approximately 6 months following LATL or RATL.
