Multiple Sclerosis- MS

Good Essays
Multiple sclerosis (MS) is a disorder of the brain and spinal cord. This potentially deliberating disease attacks the protective sheath (myelin) that covers the nerves causing problems by interfering with the communication between the brain, spinal cord and other areas of the body. It can cause various symptoms that come and go at first for several years. Though over time, some symptoms can become permanent and can cause disability. There is no cure for MS, however, various drugs and therapies may reduce the number of flare-ups and can help to ease symptoms and extent of disability. There are many thousands of nerve fibers that convey electrical impulses among different parts of the brain and spinal cord. Each nerve fiber is surrounded by a protective sheath substance known as myelin. This myelin sheath insulates much like the covering on an electrical wire and is necessary for the electrical impulse to travel properly along the nerve fiber. These nerves fibers travel from the brain and spinal cord taking messages to and from the muscles, skin, body organs and tissues. MS is believed to be an autoimmune disease because when the disease is in an active state, parts of the immune system, specifically the T cells, attack the myelin sheath that surrounds the nerve fibers in the brain and spinal cord causing inflammation. Normally the immune system would attack bacteria and viruses and so forth, but instead it attacks the parts of the body. There is no known cause for the immune system to act this way but it is speculated the result to be a viral or an environmental factor to be triggers, especially those with a certain genetic makeup. When there is inflammation surrounding the myelin sheath, it stops the nerve fibers from working p... ... middle of paper ... ...ited "Diseases and conditions Multiple Sclerosis." MayoClinic.
