Book excerpt: Benign paroxysmal positional vertigo, or BPPV, is dizziness that comes from the inner ear. It affects more than eight million people in the United States alone. The good news is that this condition can be managed at home. Carol A. Foster, an Associate Professor of Otolaryngology at the University of Colorado, Denver School of Medicine, developed a maneuver that allows sufferers to treat their own symptoms. Her YouTube video demonstrating the maneuver has more than five million views. Written in a friendly and approachable tone, Overcoming Positional Vertigo provides readers a more in-depth guide to the diagnosis of BPPV, the specifics of treatments and maneuvers, and preventative measures one can take to avoid recurrence.
