Comparison Between Electrophysiological Approaches for Presurgical Evaluation

  • J. EngelJr.

Abstract

Electrophysiological evaluation of patients with epilepsy who are candidates for surgical resection is performed for two specific purposes. The most important is precise localization of the epileptogenic lesion responsible for most or all of the patient’s habitual seizures. The second involves functional mapping that may be required to identify primary motor and sensory cortical areas that cannot be removed without producing unacceptable neurological deficit. Considerable controversy exists concerning the necessary and sufficient electrophysiological studies for both localization and functional mapping, and a variety of approaches are currently utilized.
