Auditory brain stem evoked potentials in patients with multiple sclerosis. Investigations in patients with different degrees of diagnostic probability.

Auditory brain stem evoked potentials (ABEPs) were investigated in 54 patients with the definite or presumed diagnosis of multiple sclerosis and compared with the results of 42 controls. All patients but one had no hearing impairment on clinical examinations. Investigation of ABEPs have shown to be useful when the diagnosis of multiple sclerosis is uncertain.
