What is Benign Paroxysmal Positional Vertigo (BPPV)?
Benign paroxysmal positional vertigo (BPPV) is the most common cause of vertigo. This occurs when calcium crystals in the inner ear, called otoconia, become dislodged from their normal location and float through the inner ear canal. If the crystals land in the semicircular canal–the portion of our ear that provides information to our brain about rotational movement–it causes a false sensation of spinning or whirling.
