What Is Benign Paroxysmal Positional Vertigo (BPPV)?
Benign (non life-threatening) Paroxysmal (sudden onset) Positional (occurring with certain changes in head position) Vertigo (dizziness) or "BPPV" is one of the most common causes of vertigo in adults. The classic symptom is that of vertigo, the illusion of movement, which occurs within a few seconds after a position change. Most commonly a brief sensation of spinning is experienced after lying down in bed, arising in the morning, or rolling over in bed at night, but may also occur when one looks up to a high shelf, or down under furniture. Typically, the symptoms last a few seconds or a minute or so before resolving. To many people, the BPPV experience is very frightening, and should one observe a person having this type vertigo, one would witness jerking movements of the eye called nystagmus. Sometimes these eye movements are in a circular or torsional direction. View these short videos for a demonstration of the following balance disorders:
