Benign paroxysmal positional vertigo (BPPV) is linked to poorer sleep quality and altered sleep structure. Sleep apnea, indicated by a high apnea hypopnea index (AHI), is a significant risk factor for developing BPPV.
Area of Science:
- Neurology
- Sleep Medicine
- Otolaryngology
Background:
- Benign paroxysmal positional vertigo (BPPV) is a common vestibular disorder.
- Sleep disorders are increasingly recognized as potential contributing factors to various health conditions.
Purpose of the Study:
- To investigate the association between benign paroxysmal positional vertigo (BPPV) and sleep disorders.
- To analyze subjective and objective sleep parameters in BPPV patients compared to controls.
Main Methods:
- Utilized the Pittsburgh Sleep Quality Index (PSQI) for subjective sleep assessment.
- Conducted polysomnography (PSG) for objective sleep analysis.
- Employed SPSS 23.0 for statistical comparison and regression analysis in 45 BPPV patients and 50 controls.
Main Results:
- BPPV patients exhibited significantly poorer subjective sleep quality (PSQI scores) and altered sleep structure compared to controls.
- Elevated apnea hypopnea index (AHI) was observed in BPPV patients.
- A higher AHI was independently associated with an increased risk of BPPV, with AHI ≥ 5 increasing risk by 3.94 times.
Conclusions:
- Benign paroxysmal positional vertigo is associated with diminished sleep quality and disrupted sleep architecture.
- The apnea hypopnea index (AHI) is identified as a significant risk indicator for BPPV.
