Benign Paroxysmal Positional Vertigo (BPPV) is the most common type of peripheral vertigo. It becomes more common with age. It may begin following a head trauma, or the exact cause may be unknown.

Symptoms are due to debris that has collected within a canal in the inner ear. The debris consists of small calcium carbonate crystals often referred to as “ear rocks.” These calcium carbonate crystals move through the canal as head position changes. This sends incorrect signals to the brain, producing the sensation of vertigo (otherwise known as dizziness).

Head positions and movements that provoke vertigo are often getting in or out of bed, bending over to pick something off the floor or tie shoes, or looking up when reaching for something overhead.
