Benign Paroxysmal Positional Vertigo (BPPV)
What is benign paroxysmal positional vertigo (BPPV)? Benign paroxysmal positional vertigo (BPPV) is a common inner ear disorder. With BPPV, changes in your head position — such as tipping your head backward or sitting up in bed — lead to sudden vertigo (a feeling that the room is spinning). BPPV isn’t a sign of a serious problem, and it usually disappears on its own within a few days of the first episode. (It could take several weeks for some people.) However, the symptoms of BPPV can be very frightening and may be dangerous, especially in adults over the age of 65. The unsteadiness of BPPV can lead to falls, which are a leading cause of fractures.
Who does benign paroxysmal positional vertigo affect? BPPV can affect people of all ages, but it’s most common in adults over the age of 50. About half of all people in this age range experience at least one episode of BPPV in their lifetime. BPPV can affect children, but it’s rare.
How common is BPPV? Benign paroxysmal positional vertigo is the most common inner ear disorder. In fact, approximately 20% of people who are evaluated for dizziness are diagnosed with BPPV.
Is BPPV permanent?
BPPV usually goes away on its own.
However, until it’s successfully treated, it can come back. In some cases,
months — or even years — go by before another episode occurs.
What are the symptoms of benign
paroxysmal positional vertigo?
Vertigo is the main symptom of BPPV.
This vertigo sensation can range from mild to severe and may last seconds, or
up to 1 minute. It may be accompanied by other benign paroxysmal positional
vertigo symptoms, including:
Dizziness.
Lightheadedness.
Balance problems.
Nausea and vomiting.
Blurred vision.
Nystagmus (rapid, involuntary eye
movements).
While BPPV usually only affects one
ear at a time, it can potentially affect both ears.
What triggers BPPV?
BPPV is almost always triggered by a
change in your head’s position. Some people may notice symptoms when lying down
or sitting up in bed. Others might notice symptoms when they tilt their head
back or to the side. These symptoms often worsen with age due to normal wear
and tear of the inner ear structures.
In some instances, BPPV may be a
symptom of another inner ear condition, such as:
Labyrinthitis.
Vestibular neuritis.
Acoustic neuroma.
Additionally, BPPV may accompany
migraines, or it may develop after a traumatic event — such as a fall, accident
or sports injury.
Why do changes in head position
cause BPPV?
BPPV develops when calcium carbonate
particles (otoconia) move into your semicircular canals (inner ear structures
that control balance) and become trapped. Normally, the otoconia are part of
your utricle, a vestibular organ next to your semicircular canals.
In your utricle, the otoconia may
become loose due to injury, infection or age. As your head position changes,
the otoconia roll around and push on tiny hair-like structures (cilia) within
your semicircular canals. Those cilia help transmit information about balance
to your brain. Vertigo develops when the cilia are stimulated by the rolling
otoconia.
How is benign paroxysmal positional
vertigo diagnosed?
Your healthcare provider can
diagnose BPPV during an office visit. They’ll perform a physical examination
and ask questions about your symptoms and medical history.
What is the fastest way to cure
BPPV?
The most effective benign paroxysmal
positional vertigo treatments involve physical therapy exercises. The goal of
these exercises is to move the calcium carbonate particles out of your
semicircular canals and back into your utricle. Here, the particles resorb more
easily and don’t cause uncomfortable symptoms.
You can also take motion sickness
medications to relieve your symptoms. However, you shouldn’t take these
medications long term.
Benign paroxysmal positional vertigo
exercises: How do they work?
BPPV exercises — sometimes called
canalith repositioning procedures — typically take about 15 minutes to
complete. Particle repositioning involves a series of physical movements that
change the position of your head and body. These actions shift the otoconia out
of your semicircular canals and back into their proper location in your
utricle.
A single particle repositioning
procedure is effective in treating about 80% to 90% of cases of BPPV.
Additional BPPV exercises may be needed if symptoms continue.
Your healthcare provider can perform
this maneuver during an office visit. They can also demonstrate how to do these
exercises at home to ease your BPPV symptoms.
In the meantime, here are some
step-by-step instructions to try:
Step 1: Start by sitting up on a bed
or table. Turn your head 45 degrees toward the affected ear.
Step 2: Quickly lie back, keeping
your head turned toward the affected ear as you lie back with your head
slightly over the edge of the bed or table. Wait about a minute or until you
stop having symptoms.
Step 3: Without raising your head,
turn your head quickly in the opposite direction so that your “good” ear is
parallel with — but slightly over the edge of — the table or bed. Wait about a
minute or until you stop having symptoms.
Step 4: Roll onto your side.
Continue to turn your head another 90 degrees in the same direction as step 3
so that your nose is now facing the floor. Wait about a minute.
Step 5: Keeping your chin tucked in
toward your shoulder, sit up in the direction your body is facing. Follow any
post-particle repositioning instructions given to you by your healthcare
provider.
