[The neuro-otological findings of the multiple sclerosis (author's transl)].

The present paper is based on an exact analysis of the neurootological findings in 30 cases of multiple sclerosis (MS). Ms-diagnosis was verified using Schumacher's criteria and cerebro-spinal fluid findings. Central vestibular disorders were found in most of the cases. From our observation it may be assumed that the brainstem is an early site of involvement causing imbalance which can only be verified by an accurate neuro-otological evaluation. The most important pathological findings are the following: central spontaneous nystagmus, gaze-deviation nystagmus, positional nystagmus, disinhibition of induced (caloric and galvanic) nystagmus, delay of the reversal phenomenon of galvanic nystagmus,dysrhythmia as well as distorted optokinetic nystagmus. An extensive neuro-otological investigation is of clinical importance with respect to detecting cases of MS at an early stage of this disease.
