Multiple sclerosis or MS is an autoimmune disease that attacks parts of the central nervous system components or the optic nerves, spinal cord, and brain. An irregular reaction from the immune system triggers severe inflammation that first damages the myelin. Myelin is what insulates the nerve fibers, or the fatty substance that encapsulates the nerve fibers for protection. This immune system response also causes significant damage to the specialized type of cells that produce myelin and the nerve fibers that myelin is meant to protect.
Information. The regions and tissues that sustain damage become surrounded in scar tissue, which is why the disease is named multiple sclerosis. The transmissions among the central nervous system are impaired or stopped entirely as a result of the damage that characterizes multiple sclerosis. There are four types of multiple sclerosis including relapsing remitting MS, clinically isolated syndrome, primary progressive MS, and secondary progressive MS. There is no determined cause of multiple sclerosis, however, genetics are suspected to play a role in addition immune system abnormalities and environmental factors.
