benign paroxysmal positional vertigo (bppv): what you need to know

Benign means “harmless,” while paroxysmal means “occurring in attacks.” Benign paroxysmal positional vertigo (BPPV) is one of the most common causes of vertigo, the sudden sensation of head spinning. BPPV causes brief episodes of mild to intense dizziness. It is usually triggered by specific changes in your head’s position. This might occur when you tip your head up or down, when you lie down, or when you turn over or sit up in bed.

The signs and symptoms of benign paroxysmal positional vertigo (BPPV) may include:

The signs and symptoms of benign paroxysmal positional vertigo (BPPV) may include:

BPPV is caused by a disorder of the balance organ in the inner ear. Ear crystals, also known as canaliths, are tiny calcium carbonate crystals in the inner ear that play a crucial role in maintaining balance and spatial orientation. In patients with BPPV, these crystals become dislodged and move to a different location within the balance organ, where they do not belong. This irritates the balance organ when movement occurs.

A neurologist usually makes the diagnosis based on your symptoms and the results of a physical examination. During this examination, the doctor will likely try to induce dizziness with a test called a provocation test. The diagnosis is usually clear quickly, and further testing is not necessary.

BPPV is generally easily treated. A neurologist or physical therapist can perform a head tilt procedure (Epley maneuver), which involves various head movements. The goal is to move particles from the fluid-filled semicircular canals of the inner ear into a tiny bag-like open area (vestibule) that houses one of the otolith organs in the ear. The dizziness experienced will usually disappear on its own within a few weeks to months. Occasionally, the dizziness returns or persists longer. In rare situations when the maneuver is not successful, a physician may recommend a surgical procedure.
