Multiple sclerosis, also known as MS, is a chronic and sometimes debilitating disease, in which the immune system destroys the myelin, a substance that protects the nerve fibers in the central nervous system (brain and spinal cord). Damage to the myelin causes an interruption in communication with the brain, spinal cord and other areas of your body.
What causes Multiple Sclerosis?
There is no known cause for MS. It is believed to be an autoimmune disease, a disease that attacks its own tissue. It is also believed that genetics and childhood infections may play a part in the disease.
