Acoustic truncal evoked potentials (ATEP) were studied in 24 patients in the first 48 hours after concussion of the brain. The absolute peak latency of components 1, 3, and 5, the interpeak intervals 1-3, 3-5, and 1-5, and the interaural difference were determined. The results were compared with those of examination of a control group of 24 healthy individuals. Individual and group appraisal failed to reveal any significant differences from normal values in none of the studied parameters in patients with brain concussion. The informativeness of the method in mild craniocerebral trauma is discussed.
