MS is a chronic, disabling disease of the central nervous system. It causes injury to the sheath called myelin that covers nerve fibers in the brain, spinal cord, and optic nerves.
MS is usually diagnosed in adults between the ages of 20-50. The condition also affects children in an estimated 2%-5% of cases.
