Evoked potentials

Abstract

Evoked potentials (EPs) are electrical potentials, generated by the nervous system, that are evoked by certain sensory stimuli. These tests have been used for the past 25 years by clinicians seeking to diagnose multiple sclerosis (MS). They have also been applied in research in the pathophysiology of demyelination and as an adjunct in MS therapeutic trials. EPs have found a permanent role in several diagnostic and research areas (1-5).
