A comparison between auditory and visual evoked responses in multiple sclerosis.

Sixteen patients, 6 males and 10 females, all fullfilling the criteria of clinically definite multiple sclerosis, were examined. All but one patient presented anamnestic data or clinical findings suggesting a previous or present brain stem lesion. The result obtained by visual (VER) and auditory evoked responses (ABR) were compared. In all cases abnormal VER were observed. Abnormal ABR were only recorded in 9 of the 16 patients. Consequently VER is the method of choice in establishing the multiple sclerosis diagnosis.
