Mood disorders in benign paroxysmal positional vertigo before and after treatment

Abstract

Aim Benign paroxysmal positional vertigo (BPPV) is associated with mood disorders. This study aimed to assess changes in anxiety, distress, and sleep in patients with BPPV before and after treatment. Methods Changes in mood disorders in patients with BPPV before and after treatment were evaluated with the dizziness handicap inventory (DHI), the Berg balance scale (BBS), the Hamilton Anxiety Rating Scale (HAMA), the Subjective Units of Distress Scale (anxiety level rating) (SUDS) and the Pittsburgh Sleep Quality Index (PSQI) questionnaires. Multiple-linear regression analysis was used to analyze factors influencing dizziness in patients with BPPV. Results After treatment, dizziness and mood disorders were alleviated (P < .001), and balance and sleep improved (P < .001). However, their symptoms were worse than the patients’ healthy family members who were the controls (P < .001). Multiple-linear regression analysis showed that BBS, HAMA, and SUDS influenced DHI in BPPV (r² = 0.66, P < .001). Conclusions This study identified variables that influenced BPPV, demonstrating that anxiety, distress, and impaired balance acted as independent predictors for BPPV.
