Doctor's Notes on Benign Paroxysmal Positional Vertigo
Benign Paroxysmal Positional Vertigo (BPPV) is a form of vertigo, which is a spinning sensation. BPPV is a result of a problem with the balance center (vestibular system) in the inner ear. The spinning sensation or dizziness from benign paroxysmal positional vertigo usually only lasts a short time and gets worse when the head position changes. The vertigo is intermittent and comes and goes, and it is not associated with any specific illness. Known causes of BPPV include viral infections, nerve inflammation, complications resulting from ear surgery, and side effects of medications. In about half the cases of BPPV, the cause is unknown.
