More than half of Americans—up to 180 million adults and children—have a neurological disorder, according to the American Academy of Neurology. These conditions affect your nervous system, which includes your brain, spinal cord, and nerves.
“Your nervous system controls important body functions, such as speech, movements, and thinking,” says Rani Sarkis, MD, MSc, a neurologist with the Mass General Brigham Neuroscience Institute. Dr. Sarkis cares for patients at Brigham and Women’s Hospital. Neurological disorders are the leading cause of disability and the second leading cause of death worldwide, according to the Noncommunicable Diseases (NCD) Alliance. Here, Dr. Sarkis explains warning signs of common neurological disorders and when you should see a neurologist for care.
A neurologist is a medical doctor who specializes in diagnosing and treating nervous system disorders. The prefix “neuro” stems from the Greek word “neuron,” which means nerve. A neurologist may specialize in a specific neurological disorder or treat a range of conditions.
Neurosurgeons are neurologists who have additional surgical training. “Neurologists treat conditions with medications and nonsurgical therapies,” says Dr. Sarkis. “If a patient needs spine surgery, tumor removal, an implantable device, or other surgical procedure, we refer them to a neurosurgeon.”
There are more than 400 neurological disorders. Some of the more common ones that neurologists treat include:
Signs of neurological disorders vary depending on the condition. You should contact your primary care provider (PCP) anytime you have unusual symptoms or health concerns. “If your provider sees signs of a neurological problem, they can refer you to a neurologist for a full evaluation and neurological examination,” says Dr. Sarkis.
You should also see a healthcare provider if you have neurological symptoms, such as:
A stroke cuts off blood flow to your brain, putting you at risk for irreversible brain damage, paralysis, and death. You should call 9-1-1 if you or someone you know is having a stroke. Emergency medical responders can provide treatments while on the way to the hospital, providing the best chance of recovery.
The American Stroke Association (ASA) promotes the acronym BE FAST to help you remember common stroke symptoms and the importance of getting emergency care. BE FAST stands for:
Certain conditions and environmental factors may increase your risk of neurological problems. For example:
The good news is that you can lower your risk of developing certain neurological problems. “Healthy blood circulation is as important for the health of your nervous system as it is for your heart,” says Dr. Sarkis. The NCD Alliance estimates that people could prevent 90% of strokes, 40% of dementia cases, and 30% of epilepsy cases by taking certain actions.
These actions include:
Dr. Sarkis also recommends checking your McCance Brain Care Score™ using an assessment tool developed by Mass General Brigham researchers.
“You receive a brain health score based on information about your physical health, diet and lifestyle, and social and emotional health,” he says. “You also get recommendations that you can share with your provider to improve brain health.”
