The lateralizing value of IQ in mesiotemporal epilepsy: differences between patients with unitemporal and bitemporal epileptiform discharges.

Purpose: We investigated the lateralizing ability of intelligence scores in mesial temporal lobe epilepsy (MTLE) patients according to the distribution of interictal epileptiform discharges (IEDs).

Methods: This study enrolled 82 MTLE patients. All patients had preoperative neuropsychological evaluations, including Korean Wechsler Adult Intelligence Scale.
