Objective: The purpose of this study was to analyze risk factors of residual dizziness (RD) after successful treatment for benign paroxysmal positional vertigo (BPPV) in middle-aged and older adults.
Methods: 181 patients with BPPV, after successful canalith repositioning maneuver (CRM) treatment, were recruited. All patients were divided into the middle-aged group (aged 45-59 years, n = 101) and the older group (over 60 years, n = 80). The clinical characteristics were recorded, including age, gender, numbers of maneuvers, involved canal, affected side, RD, comorbidities, dizziness handicap inventory score, and generalized anxiety disorder's 7-item scale score.
Results: The incidence of RD in the older group was significantly higher than that of the middle-aged group (p = 0.033). Multivariate logistic regression analysis shows that age (odds ratio = 1.042, p = 0.006), moderate to severe dizziness (odds ratio = 2.017, p = 0.034), and moderate to severe anxiety (odds ratio = 2.228, p = 0.017) were independently associated with RD in middle-aged and older adults.
Conclusion: Older adults exhibited higher incidence of RD after successful treatment for BPPV. Age, moderate to severe dizziness, and moderate to severe anxiety were independent risk factors of RD in middle-aged and older adults.
