Summary
Benign paroxysmal positional vertigo (BPPV) affects approximately 10.7 per 100,000 people in Japan, with higher incidence in females. The condition typically emerges in the fourth decade of life.
Area of Science:
- Otolaryngology
- Neurology
- Epidemiology
Background:
- The Research Committee of Peripheral Vestibular Disorders in Japan was established in 1980.
- Initial efforts focused on establishing diagnostic criteria for vestibular disorders like BPPV and vestibular neuronitis.
Purpose of the Study:
- To conduct epidemiological surveys on peripheral vestibular disorders in Japan.
- To estimate the incidence and identify demographic characteristics of benign paroxysmal positional vertigo (BPPV).
Main Methods:
- Data collection from a national survey of 783 vestibular disorder patients, including 101 BPPV cases.
- Data collection from the Neuro-otological Clinic of Toyama Medical and Pharmaceutical University Hospital, including 559 vestibular disorder patients, with 103 BPPV cases.
- Comparison of BPPV epidemiological features with Meniere's disease and sudden deafness.
Main Results:
- The estimated incidence of BPPV in Japan was 10.7 per 100,000 population.
- Toyama prefecture showed a higher BPPV incidence of 17.3 per 100,000 population.
- BPPV demonstrated a higher prevalence in females, with onset peaking in the fourth decade for both sexes.
Conclusions:
- Epidemiological findings for BPPV share similarities with Meniere's disease.
- Distinct epidemiological differences were observed between BPPV and sudden deafness.
