What is the definition of benign positional vertigo?

Crystals in your ear: Benign positional paroxysmal vertigo (bppv) is an ear disease. A doctor can diagnose this on a physical exam and rule out other diseases. Little "crystals" in your ear that get lose and irritate sensors in your balance organ in your ear. We all have those crystals. A neurologist or ear-nose-throat doctor can re-position them with a harmless physical maneuver.

The definition: Benign (nothing to worry about) positional (occurring only when changing head position) vertigo (the sensation of motion where there is no motion). Typically patients experience the sensation of vertigo lasting for a few seconds only when changing position. Between these episodes the patient is fine. It is helped by the epley maneuver. It is caused by loose calcium deposits in the inner ear.
