What
is a Neurologist?
Protecting
and treating the brain and nervous system is the essence of a neurologists'
work.
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 specialezed training in children's neurological
disorders.
A
neurologist's educational background and medical training includes an
undergraduate degree, four years of medical shcool, a one-year internship
and possibly additional years of training in internal medicine, and at
least three more years of specialized training in the field of neurology.
Many neurologists also have additional training in one area of neurology
such as stroke, epilepsy or movement disorders.
Neurologists
are principal care providers or consultants to other physicians. When
a person has a neurologic 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 diagnosis and treat a neurological
disorder and then advise the primary care physician managing the person's
overall health. For example, a neurologist would act in a consulting role
for conditions such as stroke, consussion 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 tratments of the brain or nervous
system.
The
human brain is the most complex structure in our world. Its intricacies
remain unsolved and unending. How we think, reason, move, sense, learn
and communicate - all are determined by the brain.
The
medical specialty of neurology focuses on the total nervous system, which
includes the brain, spine, nerves and muslces. In recent years, research
performed by neurologists has greatly advanced understanding of the brain
and nervous system. With this new understanding, neurologists are developing
new treatments and, ultimately, cures for a host of neurological diseases,
which are among the most destructive and costly public health problems
in the United States.
For
example, today neurologists can successfully treat stroke patients with
clot-busting mdedication 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
for patients with Parkinson's disease. These are just a few of the many
advances neurologists use to help improve the lives of millions of men,
women and children around the world with neurological disorders.
The
future is promising for the medical specialty of neurology. Advanced therapies,
new diagnostic techniques and the aging population ensure a strong demand
for neurologists today and in the future.
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
- Tremor
- Brain
and spinal cord injuries
- Brain
tumors
- Peripheral
nerve and muscle disorders
- Amyotrophic
Lateral Sclerosis
Many
neurological disorders can be treated. Treatment or symptomatic relief
is different for each coondition. To find treatment options, neurologist
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.
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 cognition, 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.
An
examination is used when a family doctor or non-neurologist seeks a specialized
opinion about a patient whose symptoms may involve the brain or nervous
system. The examination 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.
Common
Neurological tests utililized include image or sound wave tests and electrical
activity or response 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 filings,
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.
- 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.
- Transcranial
Doppler (TCD): This test 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 intracranial blood vessels. This test is
painless.
- 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 weakiness in the muscles or nerves.
Small needles are inserted into the muscle and mild electrical shocks
are fiven to stimulate the nerve. Discomfort may be associated with
this test.
- Evoked
Potentials (EP): The EP 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: Involve tests that diagnose specific causes of sleep problems.
To perform 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 performed is - Cerebral Spinal Fluid Analysis (Spinal
tap or lumbar puncture): This test is used to check for bleeding,
hemorrhage, infection or other disorder 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.
To
become a neurologist in the United States, extensive education and training
is required. After graduating from an undergraduate college or university,
a student must then graduate from an accredited medical school with either
a doctor of medicine or doctor of osteopathy degree.
To
be eligible for board certification, physicians planning to specialize
in neurology must enroll in a residency program accredited by the Accreditation
Council for Graduate Medical Education. These residency programs provide
supervised neurology training in both hospital and ambulatory care settings.
Educational conferences and research training also supplement neurology
residency programs.
Physicians
specializing in adult neurology will complete at least one year of an
internship (with a mininum of eight months in internal medicine) and three
years of neurology residency. Those specializing in child neurology will
spend two years in a general pediatric residency, or a year in both internal
medicine and pediatrics, or one year in research and one year in pediatrics.
Residents in child neurology then spend at least one year in adult neurology
service and two years in a child neurology service.
After
completing residency training, neurologists can choose to enroll in a
fellowship program. A fellowship offers a neurologist the opportunity
to develop expertise in a subspecialty of neurology such as stroke, dementia
or movement disorders. Fellowship programs range from one to two years.
Upon
completion of residency training, a neurologist may seek certification
from the American Board of Psychiatry and Neurology. To be eligible for
certification, applicants must:
- possess
an unrestricted state license to practice medicine;
- complete
the required years of residency training in the United States;
- pass
both a written and oral examination administered by the American
Board of Psychiatry and Neurology.
