Central disorders in vestibular neuronitis.
Between 1972 and 1993 equilibrium and audiological examinations were made on 73 patients who had been diagnosed to suffer from vestibular neuronitis. In 23 of these patients, central nervous disorders (CND) were suspected from the result of tests of positional and positioning nystagmus, smooth pursuit, optokinetic nystagmus or auditory brainstem response. In this group of patients the frequency of associated disorders and vertiginous symptoms (dizziness) was statistically higher than in the remainder 50 patients who did not have CND. In the CND group the time interval between the onset and improvement or disappearance of all vertiginous symptoms, nystagmus and canal paresis was longer than in the non-CND group.
