and the National MS Society
What is MS?
Multiple sclerosis is a chronic, unpredictable disease of the central nervous system
(CNS), which is made up of the brain, spinal cord, and optic nerves. It is thought to
be an immune-mediated disorder, in which the immune system incorrectly attacks
healthy tissue in the CNS.
MS can cause many symptoms, including blurred vision, loss of balance, poor
coordination, slurred speech, tremors, numbness, extreme fatigue, problems with
memory and concentration, paralysis, blindness, and more. These problems may
come and go or persist and worsen over time. Most people are diagnosed between
the ages of 20 and 50, although individuals as young as 2 and as old as 75 have
More than 2.3 million people are affected by MS worldwide. Because the Centers
for Disease Control and Prevention (CDC) does not require U.S physicians to
report new cases, and because symptoms can be completely invisible, the
prevalence of MS in the U.S. can only be estimated.
