Benign Paroxysmal Positional Vertigo (BPPV) is a degeneration of the inner ear that increasingly affects people as they age. It is the most common cause of vertigo (spinning sensation).
Prominent symptoms of BPPV include a sudden feeling as if everything is spinning around when the head is moved or changes position, such as when lying down, getting up, rolling over, lifting the head up and bending the head down. The symptoms last only a short time following a head movement and then gradually abate. When people with the condition move their head again in the same position, the symptoms may recur, but less intensely. In case of intense vertigo, the symptoms may include nausea and vomiting.
Vertigo may occur several times a day. The usual course of the illness is a gradual lessening of symptoms over a period of weeks to months, but the symptoms may recur after months or years.
