Association of Sarcopenia and Lower Bone Density With Positional Vertigo in the Morning: Insights From a Nationwide Survey

Morning PV is common among middle-aged and older adults and is associated with systemic frailty markers, particularly sarcopenia and bone loss, in the presence of vestibular dysfunction. These associations were more pronounced in older adults, suggesting a vestibulo-musculoskeletal interaction that may contribute to balance impairment and functional decline with aging. Screening for sarcopenia and bone health, along with vestibular and lifestyle interventions, may help reduce recurrent vertigo and improve functional aging.
