What is multiple sclerosis?

Multiple sclerosis (MS) is a disease of the central nervous system, estimated to affect 2.3 million people worldwide. It is a chronic disease in which the immune system abnormally attacks the insulation and support around the nerve cells (myelin sheath) in the brain, spinal cord and optic nerves, causing inflammation and consequent damage. MS is a leading cause of non-traumatic disability in young people, usually striking between 20 and 40 years of age. There is no cure for MS, but research continues to better understand and treat the disease.
