Benign paroxysmal positional vertigo (BPPV) is a common vestibular disorder characterized by episodes of dizziness triggered by specific changes in head position. It occurs when tiny calcium carbonate crystals, known as otoconia, become dislodged from their usual location in the utricle of the inner ear and migrate into one of the semicircular canals, disrupting normal balance signals sent to the brain. Understanding BPPV is crucial for comprehending how vestibular disorders impact postural control and balance mechanisms.
