Auditory Function in Patients With and Without Multiple Sclerosis

We propose to evaluate auditory function and neuropsychologic function in 150 Multiple Sclerosis (MS) patients and in 150 patients who do not have MS. Experimental subjects will be recruited by selecting patients with a verified diagnosis of MS from the registry of patients established by the Oregon Health Sciences University, Multiple Sclerosis Research Center. Control subjects will be matched with respect to age, to gender and to audiometric configuration.
