This document summarizes benign paroxysmal positional vertigo (BPPV), a common cause of positional vertigo. It describes the pathophysiology of BPPV, involving debris accumulating in the posterior or horizontal semicircular canals, causing vertigo when the head is moved into certain positions. It outlines diagnostic tests like the Dix-Hallpike maneuver and treatments including the Epley maneuver and particle repositioning maneuvers, which aim to move the debris out of the affected canal.
