Validation of the Wechsler Memory Scale-III in a population of people with intractable temporal lobe epilepsy.

The Wechsler Memory Scale-Third Edition (WMS-III) was developed to overcome the limitations of the Wechsler Memory Scale-Revised and is now routinely used for pre-surgical assessment of memory for patients considering elective surgery for the relief of temporal lobe epilepsy (TLE). We investigated the validity of this relatively new measure in a population of people with resistant TLE. The sample consisted of 99 patients with a diagnosis if TLE in which the epileptogenic focus was clearly identified and localised to either the right or left hemisphere.
