Multiple Sclerosis
Multiple Sclerosis or MS is a disease that affects the brain, nerves and spinal cord. It often disables the central nervous system and causes the affected person to be paralyzed or lose control of their limbs. MS was first discovered in 1868 by Jean Martin Charcot. Currently about 400,000 people in the U.S. have MS, and about 2.5 million people in the world have it.
The cause of MS is still unknown, although scientists believe that the disease is triggered by unidentified environmental factors in a person who is genetically predisposed to respond.
Some symptoms of MS are loss of vision, pain, fatigue, and impaired coordination. The symptoms vary from person to person. Some people could go their entire life without symptoms, while others may experience chronic pain.
MS can be treated, but there is not a known cure. Physical therapy and medications that suppress the immune system can help slow the disease but can not get rid of it.
MS is not spread from person to person, but could be genetic. It is not known where it came from or how to cure it but there is treatment to slow down the disease.
