The visual evoked potential (VEP) results for 404 multiple sclerosis (MS) patients are presented. In 171 patients pattern reversal with light-emitting diode (PR (LED)) VEPs and in 85 patients pattern reversal with TV (PR(TV)) VEPs also were investigated. The pathologic process of MS affects the ampl

โฆ Synopsis
Among 56 established cases of multiple sclerosis in our clinic from April 1978 to March 1985, optic neuritis was found in 38; 21 cases were bilateral. We studied pattern-evoked potentials detected with 16 electrodes placed on both the scalp and the facial area. Patternevoked potentials (PERGs) were obtainable at the facial area in multiple sclerosis patients with optic neuritis, except in long-standing cases. However, a significant reduction of amplitude was found even in cases without optic neuritis. No correlation was found between visual acuity and amplitude or peak latency of PERGs in MS patients.

The somatosensory evoked potentials (SEPs) and visual evoked potentials (VEPs) were studied in 19 patients with multiple sclerosis; 17 controls were studied during fever (38.0 degrees - 39.7 degrees C) and 2-3 days following return to normal temperature. The latencies of components N20 and P114 were
