A Short Note on Multiple Sclerosis and its Types

Multiple sclerosis is a chronic disease which effects the central nervous system, especially the brain, spinal cord, and optic nerves. This can lead to many symptoms in the body Scientists do not know exactly what causes MS, but they believe it is an autoimmune disorder that affects the central nervous system (CNS). When a person has an autoimmune disease, the immune system attacks healthy tissue in the body, just as it might attack a virus or bacteria, In the case of MS, the immune system attacks the myelin sheath that surrounds and protects the nerve fibers, which causes inflammation. Myelin also helps the nerves conduct electrical signals quickly and efficiently.
