Sleep in Different Types of Dizziness
By Joffily L, de Lima MASD, Araújo JF and 1 others.
Abstract
Objective
Sleep disturbances and dizziness are frequently comorbid, yet the specific sleep profiles across different vestibular disorders remain poorly characterized. This study aimed to investigate distinct sleep signatures in patients with benign paroxysmal positional vertigo (BPPV), vestibular migraine (VM), and persistent postural-perceptual dizziness (PPPD) compared to healthy controls.
Methods
We conducted a cross-sectional study with 90 participants: 24 healthy controls, 21 with BPPV, 23 with PPPD, and 22 with VM. Sleep was assessed using a multimodal approach: 14-day actigraphy, a single-night home sleep apnea test (Watch-PAT), and validated questionnaires, including the Pittsburgh Sleep Quality Index (PSQI), Dizziness Handicap Inventory (DHI), and Beck Anxiety/Depression Inventories.
