Is MS an autoimmune disease?
MS is presumably an autoimmune disease. In this type of disease, the body’s immune system, which normally fights infections, inappropriately attacks parts of the body; in the case of MS, myelin (the protective sheath around the nerves) and axons (a part of the nerve itself) are the immune systems targets. 3. Does MS affect survival? No, MS does not affect survival. With the current state of medical care and new treatments, MS patients have a normal life span.
