Multiple sclerosis (MS) may be a potentially disabling disease of the brain and medulla spinalis (central nervous system). In MS, the system attacks the protective sheath (myelin) that covers nerve fibers and causes communication problems between your brain and therefore the remainder of your body. Eventually, the disease can cause permanent damage or deterioration of the nerves. Signs and symptoms of MS vary widely and depend upon the quantity of nerve damage and which nerves are affected. Some people with severe MS may lose the power to steer independently or in the least, while others may experience long periods of remission with none 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.
