Benign paroxysmal positional vertigo, commonly referred to as BPPV, is a vestibular disorder that causes vertigo. It occurs when calcium deposits in the inner ear become dislodged from the otolithic membrane and settle in the semicircular canals. Any change in the position of the head causes these tiny crystals to shift, triggering dizziness.<\/p>\n\n\n\n
What Causes BPPV?\u00a0\u00a0<\/h2>\n\n\n\n
It isn\u2019t always known what causes these calcium deposits to break loose, though this is commonly the result of a head injury, inner ear infection, damage from ear surgery or prolonged back position associated with bed rest. Migraines might also play a role. Older patients are susceptible to degeneration of the otolithic membrane related to normal aging.<\/p>\n\n\n\n
