Abstract
Introduction: Sleep disorders can affect the overall health and quality of life of patients. This study was conducted to compare the differences of sleep disorders in vestibular migraine (VM) patients and benign paroxysmal positional vertigo (BPPV) patients.Methods: VM patients, BPPV patients, and healthy controls (HCs) were recruited. Pittsburgh sleep quality index and polysomnography monitoring were used as subjective and objective, respectively, evaluation methods to evaluate the sleep quality of participants in the latest month.Results: Fifty-seven BPPV patients, 48 VM patients, and 42 HCs were included in this study. There were 79.16% VM patients, 54.39% BPPV patients, and 14.28% HCs with sleep disorders. The difference in the incidence rate of sleep disorders was significant between VM patients and BPPV patients (p = 0.008) and significantly higher in both the VM group (p < 0.00001) and BPPV group (p = 0.00004) than in the HC groups (14.28%). Compared with BPPV patients, the VM patients had the significantly lower sleep efficiency (p < 0.001) and N3 (p < 0.001) and the significantly higher time of wake-up after sleep onset (p < 0.001), N1 (p < 0.001), and N2 (p < 0.001). Meanwhile, the VM patients had significantly higher incidence rates of severe obstructive sleep apnea hypoventilation syndrome (p = 0.001) and periodic leg movement in sleep (p = 0.016).Conclusion: The incidence rate of sleep disorders was significantly higher in both VM and BPPV patients than in the HC groups. To improve the curative effects, clinicians should pay more attention to the comorbidity of sleep disorders in treating VM and BPPV.

Sleep disorders can affect the overall health and quality of life of patients
57 benign paroxysmal positional vertigo (BPPV) patients, 48 vestibular migraine (VM) patients, and 42 healthy controls (HCs) were included in this study
The results showed that the proportion of patients with sleep disorders was significantly higher in the VM group (79.16%) than in the BPPV group (54.39%) (p = 0.008) and was significantly higher in both the VM group (p < 0.00001) and BPPV group (p = 0.00004) than in the HC groups (14.28%)
Summary
Sleep disorders can affect the overall health and quality of life of patients. This study was conducted to compare the differences of sleep disorders in vestibular migraine (VM) patients and benign paroxysmal positional vertigo (BPPV) patients. Sleep disorders and dizziness/vertigo are common clinical diseases with a high incidence rate. A previous study reported that there was a close relationship between sleep disorders and dizziness/vertigo: (i) sleep disorders will affect the therapeutic effect of drugs and quality of life of patients with dizziness/vertigo [1], and (ii) dizziness/vertigo attacks will interfere with the patient’s sleep [2]. Sowerby et al found that sleep apnea and daytime sleepiness were associated with idiopathic dizziness, and they suggested that sleep disorders might have diagnostic value and prognostic prediction value for vestibular diseases [3]. Its etiology is still needed to be further explored, there may be a certain relationship between sleep disorders and dizziness/vertigo.
