Multiple Sclerosis (MS)
Multiple sclerosis (MS) is a slowly progressive, degenerative condition in which the myelin sheaths surrounding nerves in the brain and spinal cord are lost. Myelin sheaths are a type of connective tissue, composed of fats and proteins, that insulate nerve fibers. They protect nerves and are required for effective transmission of nerve impulses. Indirect evidence suggests that MS may be an autoimmune disease, wherein the immune system attacks myelin in the central nervous system.
