Multiple Sclerosis
Multiple Sclerosis (MS) is a chronic, often disabling disease that randomly attacks the central nervous system (brain and spinal cord). The progress, severity and specific symptoms of the disease can not be predicted; symptoms may range from tingling and numbness to paralysis and blindness. MS is a devastating disease because people live with its unpredictable physical and emotional effects for the rest of their lives. MS is a well-known disease, but poorly understood. In the United States there are approximately 200 new cases diagnosed each week; MS is a common disease and not always caused by genetics. Therefore, I feel we all need to have a better understanding of this disease that has no cure yet. I hope to make MS more understanding in my paper. In my paper I will explain what MS is, who gets MS, what MS has to do with the metabolism, some new techniques being used to pinpoint genetic factors, what some of the symptoms of MS is, and some treatments for MS. Multiple Sclerosis Multiple sclerosis (MS) is a progressive disabling illness that affects nerve cells in the brain and spinal cord (Bernard). Under normal conditions these nerve cells are surrounded by an insulating sheath made of fatty myelin, which speeds the passage of nerve impulses. In MS, this myelin sheath is inflamed or damaged, disrupting nerve impulses and leaving areas of scarring (sclerosis). The disruption of nerve signals within the brain and spinal cord causes a variety of symptoms that may affect vision, sensation, and body movements. “These symptoms usually wax and wane through a series of relapses (episodes when symptoms suddenly get worse) alternating with remissions (periods of recovery, when symptoms improve).” (Brunnscheiler) For many patients, a long history of MS attacks over several decades leads to slowly progressing disability, but for others the disability is more rapid and severe. MS is a life-long chronic disease diagnosed primarily in young adults who have a virtually normal life expectancy. Consequently, the economic, social, and medical costs associated with the disease are significant. Estimates place the annual costs of MS in the United States in excess of $2.5 billion. (Melvin) No one knows exactly how many people have MS. It is believed that, currently, there are approximately 250,000 to 350,000 people in the United States with MS diagnosed by a physician. (Boyden) This estimate suggests that approximately 200 new cases are diagnosed...
