Relationship between benign paroxysmal positional vertigo (BPPV) and sleep quality

Abstract

Background: Benign paroxysmal positional vertigo (BPPV) is a common cause of vertigo precipitated mainly by changes in head position for example during sleep. The relationship between sleep quality and BPPV has not been studied sufficiently. We decided to compare sleep quality between posterior canal BPPV patients and controls. Methods: A total of 120 patients with posterior canal BPPV and 120 controls without BPPV were included. Demographic data as well as body mass index (BMI), cigarette smoking and medical history of the subjects were documented. The sleep quality of the participants was assessed using the Pittsburgh Sleep Quality Index (PSQI). Results: Mean scores in subjective sleep quality (0.48 vs. 0.19; P ¼ 0.002), sleep disturbances (2.97 vs. 1.85; P ¼ 0.007), use of sleep medications (0.6 vs. 0.25; P ¼ 0.001), and daytime dysfunction (0.76 vs. 0.47; P ¼ 0.07) were significantly higher in the BPPV group than in control group. Poor sleep quality (i.e., total PSQI score >5) was found in 42 patients in the BPPV group (35%) and in 16 controls (13.3%); P < 0.001. Poor sleep quality was significantly more common in those whose vertigo attacks had been started more than 12 months earlier (19 of 33 cases, 57.6%) than the patients whose symptoms had started in the past 12 months (23 of 87 cases, 26.4%); P ¼ 0.001. Conclusion: Patients with posterior canal BPPV have poorer sleep quality when compared to controls without this condition, especially in women and those with disease duration longer than 12 months. These finding suggest that close attention should be paid to sleep quality of patients with BPPV.

Chronic Vestibular Hypofunction Is Associated with Impaired Sleep: Results from the DizzyReg Patient Registry

“…A large population-based study found that sleep duration per night was either significantly shortened or very prolonged in persons with vestibular vertigo [ 16 ]. Also, looking at specific vestibular pathologies, patients with benign paroxysmal positional vertigo (BPPV) [ 17 ] or vestibular migraine [ 18 ] reported significantly worse sleep quality than healthy controls. This detrimental effect on sleep was even more pronounced in patients with a longer history of BPPV [ 17 ].…”

This detrimental effect on sleep was even more pronounced in patients with a longer history of BPPV [ 17 ]. Moreover, these combined findings lead to the hypothesis that chronic or long-term vestibular disorders such as unilateral vestibular hypofunction have an even greater negative impact on sleep quality than acute vestibular problems [ 19 ].…”

Mood disorders in benign paroxysmal positional vertigo before and after treatment

“…Previous studies have reported that the incidence of sleep disorders in patients with BPPV uctuates between 35% and 60% [21,22] . This uctuation could be related to the included population and the accuracy of the scale evaluation.…”

Understanding Benign Paroxysmal Positional Vertigo (BPPV) and Its Impact on Quality of Life: A Systematic Review

“…BPPV-related dizziness and imbalance can also result in social withdrawal and isolation due to concerns about experiencing vertigo in public settings [10,11]. Sleep disturbances are common, as positional changes in bed can trigger vertigo episodes, affecting the overall quality of rest and contributing to fatigue and irritability during the day [10][11][12]. The impact of BPPV on mental health should not be overlooked, as chronic dizziness and the associated limitations can lead to depression and decreased overall well-being [13].…”
