Multiple sclerosis is an autoimmune disease in which thebody's immune system targets the myelin sheath, a protective covering thatencases nerve cells. When these sheaths are damaged, the brain and spinal cordlose the ability to properly communicate. Symptoms are varied, and can includemuscle weakness or spasms, problems with normal locomotion, tremors, doublevision and issues with attention span, judgment and memory loss. Prognosis forthe disease varies from case to case, and though multiple sclerosis is chronicand there is no cure, a patient stricken with the disease can expect nearly anormal lifespan.
According to the
National MS Society, approximately 2.1million people suffer from multiple sclerosis globally. An estimated 100,000people have multiple sclerosis in the United Kingdom, but since "the
Centersfor Disease Control and Prevention does not require U.S. physicians to reportnew cases, and because symptoms can be completely invisible, the prevalence ofMS in the U.S. can only be estimated."
