MS is classified as an autoimmune disease, meaning the immune system is thought to be attacking normal tissue, for an unknown reason. MS should be classified as an infectious disease—it is caused by a chronic intracellular infection in the central nervous system. The immune system tries unsuccessfully to attack the intracellular infection; and the attack generates inflammation, abnormal proteins, inclusions, and damage to tissue in the central nervous system.
