| Protecting and treating the brain
and nervous system is the essence of neurologists' work.
What
is a Neurologist?
A neurologist is a medical doctor with specialized training
in diagnosing, treating and managing disorders of the
brain and nervous system. Pediatric neurologists are
doctors with specialized training in children’s
neurological disorders.
A neurologist’s educational background
and medical training includes an undergraduate degree,
four years of medical school, a one-year internship
and three years of specialized training. Many neurologists
also have additional training in one area of neurology
such as stroke, epilepsy or movement disorders.
What is the role
of a neurologist?
Neurologists are principal care providers or consultants
to other physicians. When a patient has a neurological
disorder that requires frequent care, a neurologist
is often the principal care provider. Patients with
disorders such as Parkinson’s disease, Alzheimer’s
disease or multiple sclerosis may use a neurologist
as their principal care physician.
In a consulting role, a neurologist will
diagnose and treat a neurological disorder and then
advise the primary care physician managing the patient’s
overall health. For example, a neurologist would act
in a consulting role for conditions such as stroke,
concussion or headache.
Neurologists can recommend surgical treatment,
but do not perform surgery. When treatment includes
surgery, neurologists will monitor surgically treated
patients and supervise their continuing treatment. Neurosurgeons
are medical doctors who specialize in performing surgical
treatments of the brain or nervous system.
What does a neurologist
treat?
Neurologists treat disorders of the nervous system,
brain, spinal cord, nerves, muscles and pain. Common
neurological disorders include:
Stroke
Alzheimer’s disease
Headache
Epilepsy
Parkinson’s disease
Sleep disorders
Multiple sclerosis
Pain
Movement disorders
Brain and spinal cord injuries
Brain tumors
Peripheral nerve disorders
Amyotrophic lateral sclerosis
Learning/attention problems
Cerebral palsy
How are neurological
disorders treated?
Many disorders can be treated. Treatment or symptomatic
relief is different for each condition. To find treatment
options, neurologists will perform and interpret tests
of the brain or nervous system. Treatment can help patients
with neurological disorders maintain the best possible
quality of life.
What is a neurological
examination?
During a neurological examination, the neurologist reviews
the patient’s health history with special attention
to the current condition. The patient then takes a neurological
exam. Typically, the exam tests vision, strength, coordination,
reflexes and sensation. This information helps the neurologist
determine if the problem is in the nervous system. Further
tests may be needed to confirm a diagnosis or to find
a specific treatment.
Why do patients
need a neurological examination?
An examination is used when a family doctor seeks a
specialized opinion about a patient whose symptoms may
involve the brain or nervous system. The examination
may also be performed when a patient wants a second
opinion from a neurologist. The neurologist’s
expertise in disorders of the brain and nervous system
can give patients effective diagnosis and treatment
for neurological disorders.
Who advocates for
greater patient access to neurologists?
The American Academy of Neurology supports a patient’s
choice to receive principal care services from either
a neurologist or other physician. The American Academy
of Neurology also supports direct access to neurologists
and standing referrals for those who require frequent
specialty care because of complex neurological conditions.
Advocating for patients, the American
Academy of Neurology supports legislation assuring fair
treatment of patients with neurological disorders and
access to necessary medical care.
How can research
help patients?
In recent years, research has advanced understanding
of the brain’s fundamental mechanisms. With this
new understanding, neurologists are finding new treatments
and, ultimately, cures for many neurological diseases,
which are among the most destructive and costly public
health problems in the United States.
For example, research breakthroughs now
allow neurologists to successfully treat stroke patients
with clot-busting medication proven to reduce deaths
and decrease disability. Research developments have
also produced new medications that relieve migraines,
slow the progression of multiple sclerosis and improve
movement in Parkinson’s patients. These are just
a few of the many advances gained from research that
are improving the lives of millions of men and women
around the world suffering from neurological disorders.
What are the American
Academy of Neurology and the American Academy of Neurology
Education & Research Foundation?
The goal of both the American Academy of Neurology and
the American Academy of Neurology Education & Research
Foundation is to support the best possible care for
patients with neurological disorders.
The American Academy of Neurology is a
nonprofit professional medical association of neurologists
and allied neuroscience professionals.
The mission of the American Academy of
Neurology Education & Research Foundation is to
encourage research and education in the neurosciences
while advancing public understanding of the disorders
of the brain and nervous system.
Common Neurological Tests
Image or sound wave tests
Computerized tomography
or computer assisted tomography (CT or CAT scan)
This test uses x-rays and computers to create two-dimensional
pictures of selected body parts. Dye may be injected
into a patient’s vein to obtain a better picture.
Other than needle insertion for the dye, this test is
painless.
Magnetic resonance
imaging (MRI)
An MRI is an advanced way of taking pictures of the
inner brain. It is harmless and involves magnetic fields
and radio waves. It is performed when a patient is lying
in a small chamber for about 30 minutes. Because MRI
utilizes a very strong magnet, if you have metal in
your body other than dental fillings, notify your physician.
Be sure to tell your physician if you suffer from claustrophobia
(fear of closed areas). A physician can offer recommendations
that can help you relax. This test is painless.
Transcranial Doppler
(TCD)
A test that uses sound waves to look at major blood
vessels in the brain. A microphone is placed on different
parts of the head to view the blood vessels. This test
is painless.
Neurosonography
This test uses ultra high frequency sound waves to analyze
blood flow and blockage in the blood vessels in or leading
to the brain. This test is painless.
Electrical activity or response tests
Electroencephalogram
(EEG)
The EEG records the brain’s continuous electrical
activity through electrodes attached to the scalp. It
is used to help diagnose structural diseases of the
brain and episodes such as seizures, fainting or blacking
out. This test is painless.
Electromyogram
(EMG)
An EMG measures and records electrical activity from
the muscles and nerves. This may be helpful in determining
the cause of pain, numbness, tingling or weakness in
the muscles or nerves. Small needles are inserted into
the muscles and mild electrical shocks are given to
stimulate the nerve. Discomfort may be associated with
this test.
Evoked potentials
This test records the brain’s electrical response
to visual, auditory and sensory stimuli. This test is
useful in evaluating and diagnosing symptoms of dizziness,
numbness and tingling, as well as some visual disorders.
Discomfort may be associated with this test.
Sleep studies
Involves tests that diagnose specific causes of sleep
problems. To perform the tests, it is often necessary
for a patient to spend the night in a sleep laboratory.
Brain wave activity, heart rate, electrical activity
of the heart, breathing and oxygen in the blood are
all measured during the sleep test. This test is painless.
Another common
test
Cerebral spinal fluid analysis
(Spinal tap or lumbar puncture)
This test is used to check for bleeding, hemorrhage,
infection or other disorders of the brain, spinal cord
and nerves. In this test the lower back is numbed with
local anesthesia, and a thin needle is placed into the
space that contains the spinal fluid. The amount of
spinal fluid needed to diagnose the specific problem
is removed and the needle is withdrawn. Discomfort may
be associated with this test.
