Pathophysiology and Diagnosis of BPPV

Abstract

Benign paroxysmal positional vertigo (BPPV), a disorder of the inner ear characterized by sudden, repeated episodes of positional vertigo, is the most common of the peripheral vestibular disorders and is believed to be the leading cause of vertigo worldwide. It has a favorable prognosis for recovery, with approximately 50% of cases resolving spontaneously within 3 months, and is rarely associated with any serious underlying CNS disorder [1–3].
