THE SPINNING ROOM
Vertigo
is the sensation that you are moving while you are actually
sitting or standing still. Typically, you might feel like the
room is spinning around in circles. This feeling is often
associated with nausea and a sense of imbalance. Other symptoms
might include sweating, hearing loss, ringing in your ears, and
abnormal eye movements.
Your sense of balance is controlled by delicate communication
between several locations – your eyes, your sensory nerves which
carry signal to and from your skin, muscles, and joints, and
your inner ear. Your inner ear contains the organ of balance –
the labyrinth which contains calcium particles which move when
your head is moving and send signals to your brain detecting
gravity and back-and-forth movement. If these systems are not
working, you may develop symptoms of vertigo. The symptoms of
vertigo are made worse by moving the head.
Vertigo can have many causes and, before initiating treatment,
your doctor will want to make a more precise diagnosis. Most
causes of vertigo are benign and should go away quickly but a
few rare causes can be more dangerous. Benign paroxysmal
positional vertigo (BPPV) is associated with a change in the
position of the head and is one of the most common causes of
vertigo. It occurs when the calcium particles in your inner ears
shift. BPPV becomes more common with aging and may be associated
with head trauma. Inflammation in the inner ear – vestibular
neuronitis or labyrinthitis – may be caused by a viral infection
and is characterized by sudden, intense vertigo sometimes
lasting for several days, including nausea and vomiting,
difficulty walking, and requiring bed rest. An acoustic neuroma
is a benign tumor which usually develops slowly and may be
characterized by ringing and hearing loss in only one ear.
Meniere’s disease involves excessive build-up of fluid in the
inner ear. This is characterized by episodes of vertigo lasting
30-60 minutes and typically includes ringing in the ears and
hearing loss. A vestibular migraine is a variant of a migraine
headache in which typical migraine triggers such as watching
television or riding in a vehicle may lead to vertigo symptoms
which may or may not involve headache symptoms. In very unusual
circumstances, vertigo can be a sign of more serious disease
like stroke, brain hemorrhage, or multiple sclerosis.
In diagnosing vertigo, your doctor will typically want to
understand your symptoms. He or she may ask you whether you feel
like you are losing your balance, whether you have hearing loss
or ringing in your ears, and whether you have other neurologic
symptoms like headaches or weakness in an arm or leg. Your
doctor will examine you for abnormal eye movements and sometimes
will do a special test to see if you have vertigo symptoms when
lying down and turning your head. Usually these tests will be
adequate to make the diagnosis but sometimes your doctor will
order a CT or MRI scan, blood tests, and an EKG.
The treatment prescribed will depend on your doctor’s diagnosis.
Infection of the middle ear will likely require antibiotics.
Meniere’s disease may by treated with a low-salt diet and
medication to increase urine output. BPPV is often treated with
drugs but may also require treatment with exercises which
attempt to move the calcium stones to their normal position.
Medications prescribed for BPPV often include Antivert or
Benadryl. In some cases, your primary care doctor may need to
refer you to an ear, nose, and throat (ENT) specialist for
comprehensive care.
Of course, if you have symptoms of vertigo, you should take
precautions to prevent harm to yourself and others. Do not drive
a car or operate heavy machinery until you have been thoroughly
evaluated by your physician and your symptoms have resolved. Sit
down immediately if you feel dizzy. If you need to, consider
walking with a cane. Avoid use of alcohol or other substances
which might make you more unsteady.
