Evoked potentials in multiple sclerosis.

ABSTRACT

Short-latency somatosensory short-latency auditory, and pattern evoked visual potentials were recorded in 115 patients with suspected, possible, probable, or clinically definite multiple sclerosis. An abnormality of at least one evoked potential was found in 94% of the clinically definite cases, in 67% of the summed suspected, possible, and probable cases, and in 80% of the entire series. Abnormalities of all three modalities of evoked potentials were correlated with severity of illness. Short-latency auditory evoked potential abnormalities were correlated with clinical judgement in respect to localization of lesions and activity of disease.
