Otoneurological manifestations of the Shy-Drager syndrome.
Three patients with the chief complaints of dizziness while standing up or blackouts were diagnosed correctly as having the Shy-Drager syndrome at the Department of Otolaryngology. Both the electrocardiogram R-peak to R-peak interval and the Schellong test revealed disorders of the autonomic nervous system in each of these cases. Electronystagmography also demonstrated pathology of the oculomotor system and/or central vestibular system. Postural balance was also abnormal in one of the cases. Auditory brain-stem responses were normal in all three cases.
