Auditory evoked responses in multiple sclerosis. Wave I abnormality.
Far-field short latency auditory evoked potentials (AEPs) were obtained in 40 patients with definite multiple sclerosis (MS) and 20 normal control subjects. Nine of 40 patients had abnormal wave I and normal hearing as established by pure tone audiometry. It is concluded that, in the population of patients with MS tested, slightly more than one fifth had AEP evidence of subclinical involvement of the auditory portion of the eighth cranial nerve.
