An estimated 2.8 million people worldwide have multiple sclerosis (MS). This autoimmune condition is the result of the immune system damaging parts of the nerves in the brain and spinal cord, which can lead to problems with movement, vision, balance and sensation.

While many MS symptoms can be managed, there’s currently no way to cure or prevent the condition.
