Multiple Sclerosis: Causes, Symptoms, and Treatment

What kind of doctor treats Multiple Sclerosis?
A neurologist, a doctor who treats diseases of the brain and nerves, usually treats multiple sclerosis (MS). Some neurologists have advanced training in treating MS. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is multiple sclerosis?
Multiple sclerosis (MS) is an autoimmune disease that affects the brain and spinal cord (central nervous system). In an autoimmune disease, the immune system mistakenly attacks healthy cells. MS damages myelin, the protective coating around your nerve cells. Myelin helps nerves send messages quickly. When it's damaged, messages between your brain and body slow down or get blocked.
MS is grouped into types based on how the disease changes over time. Relapsing-remitting MS is the most common type. People have flare-ups of new or worsening symptoms, called relapses, followed by periods of recovery with few or no symptoms.
Symptoms
MS symptoms vary from person to person, and they depend on which nerves are affected. Common symptoms may include:
- Blurry or double vision, or eye pain, often due to optic neuritis, which is inflammation of the optic nerve.
- Trouble with bladder control.
- Muscle weakness, stiffness, or spasms.
- Trouble with coordination, walking, or balance.
- Numbness, tingling, or a "pins and needles" feeling.
- Thinking or memory problems.
- Fatigue, dizziness, or mood changes.
Attacks can last for days, weeks, or months. Attacks are followed by remissions, which are periods of reduced symptoms or no symptoms. Fever, hot baths, sun exposure, and stress can trigger or worsen attacks.
Causes and who gets it
No one knows the exact cause of MS. Several factors may work together to raise the risk of MS, including:
- A previous infection with Epstein-Barr virus, which is the most common cause of mononucleosis (mono).
- Smoking, little sun exposure, or low levels of vitamin D.
- Certain genes. Having certain genes may increase your risk, but not everyone with these genes gets the disease.
- A family history of MS. Having a parent or sibling with MS increases the chances of getting MS.
- Living farther from the equator, where MS is more common.
MS is two to three times more common in women than in men. It most often begins between the ages of 20 and 40.
How doctors diagnose it
There is no specific test for MS. MS is diagnosed by finding signs of more than one attack on the brain or spinal cord and by checking for other conditions. Your health care provider may use several tools, including:
- A review of your health history and symptoms.
- A physical exam and neurological exam, which checks your reflexes, strength, and senses.
- An MRI scan, a scan that uses magnets to take pictures, to look for damage in the brain and spinal cord.
- Blood tests to rule out other conditions.
- A lumbar puncture (spinal tap) to check the fluid around your brain and spinal cord for signs of MS.
Treatment
There is no cure for MS, but treatment can help manage symptoms and slow the disease. Treatments may include:
- Disease-modifying medicines, which help slow MS and reduce relapses. They may be taken as pills, injections, or infusions.
- Steroids to lower the severity of attacks. They make recovery from an attack faster but do not change the long-term outcome of the disease.
- Medicines for symptoms, such as muscle stiffness or pain.
- Physical and occupational therapy to help with movement, strength, and daily activities.
Helpful steps can also include a planned exercise program early in the course of the disease and a healthy lifestyle with good nutrition and enough rest.
When to see a doctor
Symptoms of MS may mimic those of many other nervous system problems, so a provider needs to check you. Call 911 or go to the emergency room if you have chest pain or discomfort lasting two minutes or more, serious trouble breathing, fainting or loss of consciousness, or confusion or a sudden change in how you act.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. A direct primary care doctor can do an initial evaluation, coordinate care with a neurologist and therapists, and review your medicines at follow-up visits.
Common questions
Can multiple sclerosis be cured?
No. There is no cure for MS, but treatment can help manage symptoms and slow the disease.
Is multiple sclerosis an autoimmune disease?
Yes. MS is an autoimmune disease that affects the brain and spinal cord.
Does multiple sclerosis shorten life?
Often not. The outcome varies and is hard to predict. Life expectancy can be normal or almost normal.
Who gets multiple sclerosis?
Women get MS more often than men. It is most often found between ages 20 and 40, but it can happen at any age.
