Multiple Sclerosis (MS) is a disease of the central nervous system that affects over 400,000 people in the United States. MS occurs when the immune system attacks the protective myelin sheath surrounding the nerve fibers. This damages communication between the brain and body. Symptoms vary depending on location of lesions in the brain, spinal cord, or optic nerves and can include vision issues, mobility problems, numbness, and more. While there is no cure for MS, treatments aim to manage symptoms, speed recovery from attacks, and slow disease progression.
