The Clinical Reliability of Brain Stem Auditory Evoked Responses

Abstract
Auditory evoked responses thought to originate In the brain atom were Investigated In patients with and without good evidence of brain stem pathology, and In healthy volunteers. The purpose of the Investigation was to find a method of quantifying those evoked responses which would ba clinically useful. The best quantitative meaaure waa the latencies of certain poaks In the evoked response considered In combination. This measure Indicated abnormal brain stem evoked responses In 64% of patlanta with good Independent ovtdence of brain stem pathology; 23% of patients with equivocal Independent evldonco of brain atam pathology; and 0% of healthy volunteers.
