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.
