Benign paroxysmal positional vertigo (BPPV) is one of the most common causes of vertigo. It is typically associated with head movement. BPPV is thought to be due to displaced ear crystals. Like most inner ear disorders, BPPV patients experience vertigo, dizziness, loss of balance, and nausea and vomiting. More often than not it is easily diagnosed and treated, most of the time without medications using a special repositioning strategy called the Epley maneuver.
