Brain-stem auditory evoked potentials in different age groups.

Brain-stem auditory potential (BAEP) latencies were measured from individuals with normal or nearly normal hearing. Different age groups were studied separately. Males have 0.1-0.2 msec longer latencies of waves III and V and longer I-V IPLs than females in all age groups. The latencies of waves I, III and V increase 0.1-0.2 msec with increasing age, but the I-V IPL was the same in all age groups. The recognizability was very good for waves I, III and V and fairly good for waves II and IV. There was no interaural time difference.

Auditory brain stem responses in patients with vertigo.

Sixty-two patients with vertigo were examined with ABR. Eight of the 30 patients with vestibular neuronitis had abnormal ABR indicating brain stem dysfunction. Most of the patients with abnormal ABR showed continued ABR abnormality after recovery from the disease. Only one patient with epidemic vertigo had abnormal ABR, the remaining 15 patients had no signs of brain stem involvement. All 16 patients with benign positional vertigo had normal ABR.
