Benign paroxysmal positional vertigo, commonly referred to as BPPV, is a vestibular disorder that causes vertigo. BPPV is caused 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.
What Causes BPPV?
There isn’t always an apparent cause when these calcium deposits break loose; however, it 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.
What Are the Symptoms of BPPV?
BPPV is the most common cause of vertigo. The episodes of spinning may be severe but usually last for less than a minute. Other symptoms include dizziness or lightheadedness, loss of balance, blurred vision, nausea, vomiting and concentration difficulties.
How Is BPPV Treated?
When a balance specialist treats BPPV, repositioning maneuvers are typically the first step to provide relief from vertigo. These medically developed exercises move the calcium crystals from the semicircular canals and back into the utricle, where they no longer cause symptoms.
