Description

Subjects were 626 patients reporting vertigo or dizziness seen at the University Hospital Department of Otolaryngology from April 2001 to September 2003. Patients were diagnosed based on diagnostic criteria prescribed by the Japan Society for Equilibrium Research. The most common peripheral vestibular disorder was benign paroxysmal positional vertigo (32%), followed by Meniere's disease (12%). All peripheral vestibular disorders accounted for 65%. Central vestibular disorder accounted for 7%, of which space-occupying lesions in the posterior fossa accounted for 1.0% and cerebral infarction 1.9%. Dizziness due to orthostatic hypotension accounted for 4.0%. Among past reports on clinical statistics of vertigo, the incidence of vertigo and dizziness disorders differed greatly, but our research and the past 2 reports based on diagnostic criteria prescribed by the Japan Society for Equilibrium Research showed almost the same incidence, i. e., BPPV of 30-40%, Meniere's disease of 7-10%, other peripheral vestibular disorders of 15-20%, and central vestibular disorder of 6-8%. Unified diagnostic criteria are thus important in the statistical analysis of vertigo disorders.
