Investigation of the relationship between posterior semicircular canal benign paroxysmal positional vertigo and sleep quality

Aim: The aim of this study was to investigate the relationship between posterior semicircular canal benign paroxysmal positional vertigo (P-BPPV) and sleep quality. Material and Methods: In this prospective study, 35 patients with P-BPPV and 30 healthy volunteers were evaluated. Pittsburgh Sleep Quality Index (PSQI) and Insomnia Severity Index (ISI) were applied to all subjects. Adult Dizziness Handicap Index (ADHI) was applied to the patients with P-BPPV. The PSQI and ISI scores of the P-BPPV patient group and the control group were compared. ADHI scores were compared with PSQI and ISI scores. PSQI and ISI scores of recurrent P-BPPV patients and P-BPPV patients who had their first attack were compared. Results: The PSQI and ISI scores of the patients with P-BPPV were significantly worse than the control group (p=0.02, p
