Review of the 20-year UCLA experience with surgery for epilepsy1

Author and Disclosure Information


During the past 20 years, a series of 175 patients with medically intractable complex partial epilepsy has been treated surgically or evaluated with depth electrodes at the UCLA Center for the Health Sciences. Lately, emphasis has been placed on the value of performing the operation on only those patients who have undergone independent evaluations to determine a focal cerebral dysfunction which would confirm electroencephalographic localization. Depth-electrode implantation and telemetric recording of seizures remain an important part of the UCLA evaluation protocol for many of these patients; however, recent experiences have shown that other tests may supersede depth recordings for selected persons.
