What is the definition or description of: benign positional vertigo?

BPPV: This is an inner ear disorder in which the nerve endings in our ears that normally contribute to our sense of balance are inappropriately sending signals to our brain. These signals give us the sense we are moving when in fact we are not, and this results in vertigo. It is caused when microscopic particles of calcium carbonate (otoliths) in the inner ear are dislodged. www.mainlineent.com.

Quick vertigo: Benign paroxysmal positional vertigo or bppv is the most common cause of vertigo. The sensation of spinning is classically triggered by changes in head position and is self limited. The spinning lasts seconds to minutes. A popular theory is that there is debris loose in the fluid of the semicircular canal of the inner ear. This debris can move the fluid triggering certain nerves to cause vertigo.
