Benign Paroxysmal positional vertigo (BPPV)
Benign Paroxysmal Positional Vertigo (BPPV) is a common disorder of the inner ear that causes episodes of intense dizziness and vertigo. It is caused by an imbalance of calcium crystals in the inner ear. BPPV can be triggered by certain head movements, such as turning over in bed or tilting the head back. During an episode, a person may experience a feeling of spinning, loss of balance, nausea, and vomiting.
BPPV is typically diagnosed through a physical examination and a series of tests, including a Dix-Hallpike maneuver, which is done by moving the person’s head in specific directions while lying down. Other diagnostic tests may include an audiogram and an electronystagmogram.
