Demyelinating diseases are uncommon conditions in which the myelin sheath is attacked, resulting in neurodegeneration and eventual disability. The myelin sheath surrounds axons in the brain and peripheral nervous system. Axons are nerve cells that extend neurons. While neurons coordinate sensory and motor information in the brain, the axons deliver that information to where it needs to go; either between neurons or outside the brain to organs and tissues within the body.
