When you have multiple sclerosis (MS), your body’s immune system attacks your central nervous system.
But no one knows exactly what triggers the immune system to attack the central nervous system. Most experts believe it occurs when a person with a genetic predisposition to MS is exposed to certain environmental conditions,
Since it isn’t known exactly what causes MS, physicians can’t foresee with certainty who will develop the disease, but they do know there are some things that may put you at higher risk.

Multiple sclerosis (MS) is a potentially disabling disease of the brain and spinal cord (central nervous system).
In MS, the immune system attacks the protective sheath (myelin) that covers nerve fibers and causes communication problems between your brain and the rest of your body. Eventually, the disease can cause permanent damage or deterioration of the nerves.
Signs and symptoms of MS vary widely and depend on the amount of nerve damage and which nerves are affected. Some people with severe MS may lose the ability to walk independently or at all, while others may experience long periods of remission without any new symptoms.
There’s no cure for multiple sclerosis. However, treatments can help speed recovery from attacks, modify the course of the disease and manage symptoms.
