- Multiple Sclerosis - Causes, Symptoms And Treatment
Multiple sclerosis is a chronic, progressive, degenerative disorder that affects nerve fibers in the brain and spinal cord. A fatty substance surrounds and insulates nerve fibers and facilitates the conduction of nerve impulse transmissions. In MS, inflammation causes the myelin to degenerate and eventually disappear. Consequently, the electrical impulses that travel along the nerves decelerate. Multiple sclerosis is unpredictable and varies in severity. In some people, multiple sclerosis is a mild illness, but it can lead to permanent disability in others. MS is two to three times as common in females as in males and its occurrence is unusual before adolescence.
About 250,000 to 350,000 people in the U.S. have MS. Usually, a patient is diagnosed with MS between 20 and 40 years of age, but MS has been diagnosed as early as age 15 and as late as age 60.
