Auditory brain stem responses were recorded in 10 eating disorder patients and 10 normal control subjects. Absolute latencies, interwave latencies, absolute amplitudes, and amplitude ratios were investigated. A nonsignificant difference was found between the eating disorder group and the normal control group as far as the absolute latencies and interwave latencies were concerned. But the eating disorder patients had significantly smaller amplitude ratios (HI/I, IV‐V/I) and absolute amplitude (V) than did the control subjects. These findings suggest that some dysfunction exists in the region of brain stem. It may be related with the pathophysiology in patients with eating disorder.
