Autoimmune disease
Multiple sclerosis

Multiple sclerosis (MS) is a neurodegenerative disease in which the immune system attacks myelin, a protective covering of nerve fibers in the central nervous system, causing communication problems between the brain and the rest of the body. Symptoms can include fatigue, difficulty walking, numbness or tingling, muscle weakness, and problems with coordination and balance. MS is associated with an increased risk of central nervous system cancer, primarily in the brain.
