What Is Multiple Sclerosis?

Multiple Sclerosis

Say: MUL-tih-pul sklare-OH-sis

Nerves are great for sending messages between the brain and the body. But nerves don't work the right way in a person who has multiple sclerosis, or MS. That means the signals don't get where they need to go.

People with MS may have trouble walking. They may have numbness or tingling in their hands or feet. They may have trouble seeing or remembering things. MS is mostly something that adults get. There is no cure for MS, but medicines can help control symptoms.
