The use of the auditory evoked potential in the diagnosis of multiple

sclerosis.

K, Rudge P

Auditory evoked potentials, both early and middle components, were recorded

from 227 patients with a variety of conditions including multiple sclerosis,

brain stem vascular disease, intracranial tumours and Arnold-Chiari

malformation. Abnormalities were found in a substantial proportion of

patients with definite multiple sclerosis and a smaller proportion of those

in the less definite clinical categories of this condition. There was a high

correlation between clinical evidence of brain stem involvement and an

abnormal auditory evoked potential in multiple sclerosis. Abnormalities were

also found in a few patients presenting with an isolated episode of central

nervous system dysfunction involving the brain stem. The auditory evoked

potential was abnormal in other patients with known diagnoses including half

of those with Arnold-Chiari malformation. Tumours involving the brain stem

caused abnormalities of the brain stem evoked potentials in some cases and

more frequently distortion of the middle components. The specificity of these

auditory evoked potential abnormalities to multiple slcerosis is discussed.
