Auditory brain stem responses in patients with vertigo

Abstract

Patients (62) with vertigo were examined with ABR [auditory brainstem response]. Of the 30 patients with vestibular neuronitis, 8 had abnormal ABR indicating brain stem dysfunction. Most of the patients with abnormal ABR showed continued ABR abnormality after recovery from the disease. Only 1 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.
