前庭神経炎症例における中枢障害所見の検討

抄録

Equilibrium and audiological examinations were conducted in 73 patients with a diagnosis of vestibular neuronitis during 1972 and 1993. In 23 patients central nervous system disorders were suspected from the results of tests of positional and positioning nystagmus, smooth pursuit, optokinetic nystagmus or auditory brainstem response. In this group of patients the mean age and the frequency of associated disorders and vertigo (dizziness) were significantly higher than in other patients, and the time intervals between the onset and improvement or disappearance of vertigo, nystagmus and canal paresis were longer. These findings suggest that aging and associated disorders of the central nervous system increase susceptibility to vestibular neuronitis.
