What is Multiple Sclerosis?
Multiple Sclerosis, or MS, is a disease of the central nervous system where nerve impulses are disrupted. With MS, the immune system attacks the nervous system. The protective cover over the nerves, called myelin, is damaged or destroyed, and nerve impulses no longer flow smoothly. The scar tissue on the myelin is called sclerosis, giving the disease its name. MS occurs in people who respond to environmental factors that trigger the disease.
