Blink reflexes elicited by electrical, acoustic and visual stimuli. II. Their relation to visual-evoked potentials and auditory brain stem evoked potentials in the diagnosis of multiple sclerosis.
Blink reflexes, elicited by flashes of light, tone bursts and electrical stimuli, as well as checkerboard reversal visual-evoked potentials and brain stem auditory evoked potentials were investigated in 55 patients with different degrees of diagnostic probability of multiple sclerosis. It is demonstrated that electrically and acoustically elicited blink reflexes are simple but rather sensitive methods of indicating brain stem lesions. They should be used complementarily with brain stem auditory potentials. Flash-elicited blink reflexes, although sensitive, are thought to be of minor importance, since they give only restricted localizing information.
