Multiple sclerosis (MS) is a chronic condition affecting the central nervous system, comprising the brain and spinal cord. Exactly why MS occurs is unknown, and treatment options are still limited.

With MS, this myelin coating is degraded over time, slowing or entirely stopping signals from traveling along nerve fibers. This leads to problems with muscle weakness, coordination, and balance.
