What is Benign Paroxysmal Positional Vertigo – BPPV?
(Symptoms, Causes & Treatment)
According to Johns Hopkins University, Benign Paroxysmal Positional Vertigo (BPPV) is the most common of vestibular disorders and the one that is most easily treated. In the majority of patients, BPPV can be cured with a simple physical therapy maneuver. BPPV is most common in people over the age of 60, but can affect anyone.
BPPV occurs when otoconia (small microsized calcium crystals) become dislodged from their normal location on the utricle (an inner ear sensory organ). If the otoconia become detached, they are free to flow in the fluid filled spaces of the inner ear (including the semicircular canals which sense the rotation of the head) and form into clumps. Because they are heavy, they migrate into the lowest part of the inner ear, the posterior semicircular canal. Once in the semicircular canal, they may still move when the head changes position, such as looking up or down, over the shoulder. It is the movement of these stones that causes an unwanted flow of fluid in the semicircular canal even after the head has stopped moving. This leads to a false sense that the head and body are spinning around or that the world around you is spinning around.
