Neurologists are medical doctors who specialize in diagnosing and treating disorders of the brain, spinal cord, and nerves. They complete at least 12 years of education and training before practicing independently, making them among the most extensively trained physicians in medicine. If you or someone you know has been referred to a neurologist, or you’re simply curious about what they do, here’s what sets them apart from other doctors.
What Neurologists Do
A neurologist’s core job is figuring out what’s going wrong in the nervous system and managing it, usually without surgery. They handle conditions that can affect nearly every part of the body, since the brain and nerves control everything from movement and speech to memory and sleep. Some of the most common conditions they manage include epilepsy, multiple sclerosis, Parkinson’s disease, Alzheimer’s disease and other dementias, stroke, ALS (Lou Gehrig’s disease), and brain or spinal cord injuries.
Neurologists also treat problems that might seem unrelated to the brain at first glance, like chronic pain, carpal tunnel syndrome, and sleep disorders. Because so many symptoms can trace back to the nervous system, neurologists often serve as diagnostic detectives, piecing together clues from a patient’s history, physical exam, and testing to identify what’s causing the problem.
How They Differ From Neurosurgeons and Psychiatrists
The simplest distinction between a neurologist and a neurosurgeon: they both treat the same organ system, but neurosurgeons operate and neurologists don’t. When a neurologist discovers a structural problem like a brain tumor through imaging, they’ll refer the patient to a neurosurgeon. After surgery, the neurology team often takes over again for chemotherapy coordination and long-term care. The two specialties frequently work as one team, each handling different aspects of the same patient’s needs.
The line between neurology and psychiatry is blurrier. Historically, neurologists focused on brain disorders that present with physical signs you can detect on an exam, like the tremor of Parkinson’s or the weakness of a stroke. Psychiatrists focused on disorders of mood and thought, like depression, anxiety, and schizophrenia, where a standard neurological exam may appear normal. In practice, there’s significant overlap, and some neurologists subspecialize in behavioral neurology and neuropsychiatry to bridge that gap.
Education and Training
Becoming a neurologist requires four years of college, four years of medical school, and then a residency program. Adult neurology residencies are four years long, including an internship year in internal medicine. Child neurology residencies run five years and include two years of pediatrics training. That’s a minimum of 12 to 13 years of education after high school before a neurologist can practice independently.
To become board certified, neurologists must pass an examination administered by the American Board of Psychiatry and Neurology. This requires completing an accredited training program, holding an unrestricted medical license, and demonstrating clinical competence through a formal evaluation process. Board certification isn’t a one-time achievement. Neurologists participate in a continuing certification program throughout their careers.
Subspecialties Within Neurology
Neurology is broad enough that many neurologists narrow their focus further through fellowship training. There are currently 31 types of neurology subspecialty fellowships in the United States, with 17 accredited by major credentialing bodies. Some of the largest include pain medicine (104 fellowship sites nationwide), vascular neurology focused on stroke (99 sites), clinical neurophysiology (89 sites), sleep medicine (84 sites), and epilepsy (77 sites).
Other subspecialties address more specific populations or conditions. Movement disorder specialists focus on Parkinson’s disease and related conditions. Neuro-oncologists treat nervous system cancers. Neuromuscular medicine specialists handle diseases affecting the connection between nerves and muscles, like myasthenia gravis. Headache medicine specialists manage chronic migraines and other headache disorders. There are even subspecialties in autonomic disorders, which affect involuntary functions like heart rate and digestion, and geriatric neurology for age-related brain conditions.
What Happens at a Neurology Appointment
A neurological exam tests six main areas: mental status, cranial nerves, sensory function, motor strength, cerebellar function (which controls balance and coordination), and reflexes. Much of this exam looks deceptively simple. Your neurologist might ask you to follow a finger with your eyes, push against their hand, walk heel-to-toe in a straight line, or identify a light touch on your skin. Each task is testing a specific pathway in the nervous system, and subtle abnormalities can point toward a diagnosis.
Beyond the physical exam, neurologists rely on several key diagnostic tools. An EEG records the brain’s electrical activity and is particularly useful for identifying seizure disorders and certain sleep disturbances. Nerve conduction studies and electromyography help determine whether muscle weakness or numbness is caused by a problem in the nerve, the spinal nerve root, the connection between nerve and muscle, or the muscle itself. These tests can pinpoint conditions ranging from a ruptured disc to diabetic neuropathy.
Imaging plays a major role too. CT scans can quickly identify bleeding, strokes, tumors, and other structural abnormalities in the brain. MRI provides more detailed images of both the brain and spinal cord. A spinal tap, or lumbar puncture, involves collecting a small sample of the fluid surrounding the brain and spinal cord. This fluid is checked for signs of infection, inflammation, tumors, or bleeding, and the procedure can also measure pressure inside the skull.
When You Might Be Referred to One
Most people see a neurologist after a referral from their primary care doctor, though the specific symptoms that prompt a referral vary widely. Persistent numbness or tingling in the hands and feet, particularly in a “glove and stocking” pattern, often warrants neurological evaluation once common causes like vitamin B12 deficiency, thyroid problems, and diabetes have been ruled out. Sudden, one-sided numbness requires urgent evaluation for a possible stroke.
Tremors are another common reason for referral. A tremor that appears on one side of the body, or one accompanied by stiffness, slowness, balance problems, or difficulty walking, should be evaluated by a neurologist before any treatment is started, as these features can indicate Parkinson’s disease. Essential tremor, the most common type, is sometimes managed by a primary care doctor first, with neurological referral if initial treatment doesn’t help or the tremor becomes disabling.
Chronic headaches, unexplained seizures, memory problems, persistent dizziness, difficulty speaking or swallowing, and sudden changes in vision are all symptoms that can lead to a neurology referral. Because the nervous system touches every part of the body, neurologists often see patients whose symptoms have puzzled other specialists, making their diagnostic skills one of their most valuable tools.
