Multiple sclerosis, or MS, is a disease of the nervous system that can affect the brain and spinal cord. In the United States, MS affects approximately 350,000 people and more than two million people worldwide.

MS symptoms are caused by the progressive loss of myelin, the outer protective lining of nerve fibers. Myelin is like the coating around an electrical wire: Without enough myelin, nerve signals have trouble passing through the nerves. The full cause of MS is not completely understood, but it’s partly due to the body’s immune system mistakenly attacking myelin cells. That’s why multiple sclerosis is called an autoimmune disease.

There is more to learn about this condition, which underscores the importance of raising awareness around the globe. March is National MS Awareness Month. Donate to the National Multiple Sclerosis Society, or any of the Community Health Partner Charities, through our giving portal.
