If it feels like the room is spinning around you and you have
trouble staying steady on your feet, you might have a type of
dizziness called vertigo. Vertigo can be a symptom of several
health conditions affecting your inner ear and your vestibular
system. The vestibular system is what helps you sense your
body's position in space, coordinate your movements, and stay
upright and balanced.
Benign
paroxysmal positional vertigo
Benign paroxysmal positional vertigo (BPPV) is a common inner
ear disorder. With BPPV,
tiny bits of calcium in part of your inner ear get loose and
move to places they don't belong. The system doesn't work the
way it should and sends your brain the wrong signals.
It's often caused by the natural breakdown of cells that happens
with age. A head injury can cause it, too.
You'll feel it briefly when you tilt or turn your head, and
especially when you roll over in bed or sit up. BPPV isn't
serious and usually goes away on its own. If not – or you'd like
to help it along – it can be treated with special head exercises
to get the pieces of calcium back in place. Your doctor can help
you perform these exercises.
Meniere's disease
People with Meniere's disease have too much fluid in their inner
ear. This condition brings on intense periods of vertigo that
can last hours. You may feel fullness or pressure in one ear.
Other symptoms include ringing in your ears, hearing loss, and
nausea. You may feel exhausted after the attack passes.
Doctors don't know what causes it, and there's no cure for it.
It's usually treated with diet changes (a low-salt diet) and
medicine to control the dizziness.
Inner
ear infection
Inflammation of the nerves in your ears due to infection also
causes vertigo. Vestibular neuritis and labyrinthitis are two
types of infections that can cause problems in the inner ear.
Vestibular neuritis affects your vestibular nerve, and labyrinthitis affects
both your vestibular nerve and your cochlear nerve – a nerve in
your ear involved in hearing. These infections are often caused
by a virus.
Central vertigo
It occurs when you have a condition affecting your brain,
like an infection, stroke or traumatic brain injury. People
with central vertigo usually have more severe symptoms like
severe instability or difficulty walking.
Other
causes of vertigo
Some other causes of vertigo include:
- A noncancerous tumor that puts pressure on the vestibular
nerve called an acoustic neuroma
- Some medications that hurt the inner ear, such as aminoglycoside
antibiotics, diuretics, or salicylates
- Head injury
- Stroke
- Multiple sclerosis
- Vestibular migraine
