BackgroundThis study compared the incidence of Meniere's disease (MD) in the elderly aged >65 years between the first (2001-2010) and second (2011-2020) decades to investigate the evolution of geriatric MD.MethodsTotally, 1605 and 2550 patients with definite MD were experienced at the neurotological clinic during the first and the second decades, respectively. All patients were divided into three groups by 30-year age band, namely elderly (aged 65-94 years), adult (aged 35-64 years) and young (aged 5-34 years) groups, and underwent an inner ear test battery. Factors relating to the incidence of MD during the past two decades were analyzed.ResultsThe elderly MD group comprised 198 (12.4%) of 1605 MD cases during the first decade, and 463 (18.2%) of 2550 MD cases during the second decade, showing a significantly increased incidence of elderly MD. Correlation between annual life expectancy (x) in Taiwan and annual prevalence (y) of the elderly MD in relation to total MD cases revealed y = 0.023x - 1.660 via linear regression analysis. In contrast, the adult MD group significantly differed in terms of age and gender ratio, but not incidence, between the two decades. Conversely, the young MD group exhibited significantly decreased incidence from the first decade (22.3%) to the second decade (13.8%).ConclusionEvolution of geriatric MD during the past two decades reveals an increased incidence of the elderly MD patients, likely due to increased life expectancy coupled with altered life style.Copyright © 2022 Formosan Medical Association.
