Introduction[edit | edit source]
Benign paroxysmal positional vertigo (BPPV) is the most common cause of vertigo that arises from a peripheral vestibular disorder. It accounts for 20 to 30 percent of all patients seen for vertigo in clinics that specialise in dizziness.[1]
While the overall incidence of BPPV in the general population is around 2.5 percent,[1] it is more common in older adults. Some studies show that 50 percent of older adults have BPPV.[2]
Symptoms tend to be provoked by head movements, such as:[3]
- Looking up
- Lying down flat quickly
- Bending forwards
- Rolling in bed
BPPV is a biomechanical problem in which one or more of the semicircular canals is inappropriately excited, resulting in vertigo, nystagmus and occasionally nausea.[3] It occurs when there is displacement of calcium-carbonate crystals or otoconia from the utricle into one of the three fluid-filled semicircular canals of the inner ear.[3][4] For more information on the anatomy of the vestibular system, please click here.
