Anxiety characteristics in benign paroxysmal positional vertigo: first vs. recurrent episodes

Abstract

Purpose To assess the difference in state and trait anxiety levels in patients with Benign Paroxysmal Positional Vertigo (BPPV) at the first episode (FE) versus recurrent episodes (RE), before and after vestibular physiotherapy. A secondary objective was to assess the difference in the prevalence of underlying health conditions between FE and RE BPPV patients. Methods Fifty-five patients with BPPV, aged 40–70, were recruited. The diagnosis of BPPV was confirmed based on subjective complaints of vertigo and positive results from the Dix–Hallpike and Supine Roll tests. Twenty-four patients were in their FE, and 31 had RE. All patients completed the State–Trait Anxiety Inventory (STAI) questionnaire three times; before, immediately after, and a week after vestibular physiotherapy treatment. Results The RE group demonstrated higher trait anxiety than the FE group in all testing points: before treatment (median value of 38 versus 29, p-value = 0.02), immediately after treatment (median value of 36 versus 28, p-value < 0.01) and a week later (median value of 38 versus 28, p-value < 0.01). State anxiety decreased immediately after treatment in both groups, but at the second session, it was significantly higher in the RE than in the FE group (median value of 38 versus 28.5, p-value = 0.03). Hypothyroidism was significantly more frequent in the RE group (RE 16%, FE 0%, p-value = 0.04). Conclusions Based on the current study’s findings, we recommend assessing anxiety levels in patients with recurrent BPPV and consider referring them for appropriate treatment when necessary.
