How We Help BPPV in Older Adults

BPPV a Common Cause of Dizziness in Seniors

BPPV happens when loose crystals (otoconia) fall out into one of the canals

One of the most common causes of dizziness in seniors is Benign Paroxysmal Positional Vertigo, or BPPV.  This happens when calcium carbonate crystals (otoconia), that we all have in one part of the inner ear, become displaced into one or more of the inner ear’s semicircular canals. When otoconia move into one of the inner ear’s semicircular canals where they aren’t supposed to be, that canal sends different information to the brain about certain head movement than the other ear.  Both ears should be saying the same thing about what our head movements are, and they should be agreeing with what our eyes are seeing and our joints are feeling.  When there is a mismatch in these systems, it makes us feel dizzy.  BPPV is the most common cause of vertigo, which is an illusion of the room spinning or moving.

What Happens in the Inner Ear When the Room Starts Spinning?

Taking apart what's really happening to a BPPV patients as they experience vertigo can help patients to feel less frightened by it. The start of the problem often happens at night when a person is laying down.  Loose crystals can fall out into one of the canals, and when the person gets up in the morning these crystals are trapped out in the canal.  From that point forward any time the person moves their head into a position where gravity moves the loose crystals, that canal sends a message to the brain that is an error.  The most commonly provoking movements are getting in or out of bed, rolling over in bed, bending, looking upward and quick head movements.

Because of the connections between our inner ears and our eye muscles, during the time the crystals are moving, the incorrect signal makes our eyes move in a way that makes it appear like the room is spinning.  In the most common form of BPPV, the spinning only lasts until the crystals stop moving because they’ve reached the lowest point in the canal, which takes less than 1 minute.  If things are spinning longer than 1 minute, it is either a rarer form of BPPV called cupulolithiasis, or it is a condition other than BPPV.  A well-trained Vestibular Rehabilitation Therapist, ideally using special goggles allowing for a magnified look at your eye movements, can help you determine whether or not you have BPPV, and if so, what form you’ve got and what canal the loose crystals have moved into.  This then determines the treatment maneuver that should be used.

How We Treat Bening Paroxysmal Positional Vertigo (BPPV)

To help sufferers of BPPV a vestibular rehabilitation professional uses techniques to locate the crystals that are out of place and employs maneuvers to reposition them back to the correct chamber with the help of gravity.  Typically after 1-3 visits peoples’ BPPV is corrected.   Sometimes people have some mild sensitivity to motion and/or some balance issues that persist after the BPPV is cleared, but these are typically easily remedied with some simple home exercises.
