Benign Paroxysmal Positional Vertigo (BPPV) is a common inner ear disorder that causes brief episodes of dizziness or spinning sensations. It occurs when tiny calcium crystals in the inner ear become dislodged and move into the semicircular canals, disrupting the normal balance signals sent to the brain. This can happen due to head injuries, aging, or sometimes without any clear reason. Symptoms of BPPV are often triggered by specific head movements, such as turning over in bed or looking up. While the episodes can be unsettling, BPPV is generally considered harmless and can often be treated effectively with physical therapy maneuvers, such as the Epley maneuver.
