Among those who live until their 80s, 10% have been affected. Approximately 2.4% of people are affected at some point in time. The first medical description of the condition occurred in 1921 by Róbert Bárány. Short-term self-resolution of BPPV is unlikely because the effective cure maneuvers induce strong vertigo which the patient will naturally resist and not accidentally perform. One can needlessly suffer from BPPV for years despite there being a simple and very effective cure. When untreated, it might resolve in days to months however, it may recur in some people.

BPPV is not a serious medical condition, but may present serious risks of injury through falling or other spatial disorientation-induced accidents.

There is tentative evidence that betahistine may help with vertigo, but its use is not generally needed. Medications, including antihistamines such as meclizine, may be used to help with nausea. īPPV is easily treated with a number of simple movements such as the Epley maneuver or Half Somersault Maneuver (in case of diagonal/rotational nystagmus), the Lempert maneuver (in case of horizontal nystagmus), the deep head hanging maneuver (in case of vertical nystagmus) or sometimes the less effective Brandt–Daroff exercises. In typical cases, medical imaging is not needed. Diagnosis is typically made when the Dix–Hallpike test results in nystagmus (a specific movement pattern of the eyes) and other possible causes have been ruled out. When found, the underlying mechanism typically involves a small calcified otolith moving around loose in the inner ear. Often, a specific cause is not identified. It can result from a head injury or simply occur among those who are older. īPPV is a type of balance disorder along with labyrinthitis and Ménière's disease. BPPV is one of the most common causes of vertigo.

Each episode of vertigo typically lasts less than one minute. This can occur with turning in bed or changing position. Symptoms are repeated, brief periods of vertigo with movement, characterized by a spinning sensation upon changes in the position of the head.
