What is multiple sclerosis?
Multiple sclerosis, often called MS, is a disease that affects the central nervous system—the brain and spinal cord. It can cause problems with muscle control and strength, vision, balance, feeling, and thinking.
Your nerve cells have a protective covering called myelin. Without myelin, the brain and spinal cord can't communicate with the nerves in the rest of the body. MS gradually destroys myelin in patches throughout the brain and spinal cord, causing muscle weakness and other symptoms. These patches of damage are called lesions.
MS is different for each person. You may go through life with only minor problems. Or you may become seriously disabled. Most people are somewhere in between. Generally, MS follows one of four courses:
- Relapsing-remitting, where symptoms fade and then return off and on for many years.
- Secondary progressive, which at first follows a relapsing-remitting course and then becomes progressive. “Progressive” means it steadily gets worse.
- Primary progressive, where the disease is progressive from the start.
- Progressive relapsing, where the symptoms come and go but nerve damage steadily gets worse.
Whatever your symptoms are, treatment and self-care can help you maintain your quality of life. There is no cure for MS, but it is not fatal except in rare cases.
