title: Clinical features of benign paroxysmal positional vertigo (BPPV) in Taiwan: differences between young and senior age groups.
abstract: BPPV is a common cause of vertigo. Several treatment procedures can facilitate recovery. In this study, we aimed to identify the demographic features, resolution and recurrence rates and impacts on daily activities in BPPV patient between young and senior age groups in Taiwan. This retrospective study recruited 218 patients of BPPV. Medical history, canal involvement, treatment required for complete resolution, symptom free period and recurrence rates were evaluated between the two age groups. Up to 80.7% of patients were successfully treated by a single treatment. For patients aged more than 65 years, the recurrence rate was 1.7 times higher than that in the younger age group (p = 0.07). The symptom-free period before recurrence was nearly 2.2 times longer in the senior age group (p = 0.03). Work-related activities were influenced more by BPPV in the younger age group (p = 0.03). We conclude that BPPV is prone to occur and recur in people of senior age. Clinicians should have the knowledge to diagnose different types of BPPV and treat it accordingly to prevent further complications.
