1 Multiple sclerosis (MS) is a disease that causes demyelination (disruption of the myelin that insulates and protects nerve cells) of spinal nerve and brain cells. 2  Although the exact case is unknown, multiple sclerosis is considered to be an autoimmune disease.
Autoimmune disease can be either organ-specific illnesses (eg, thyroid disease, type 1 diabetes mellitus, myasthenia gravis) or systemic illnesses (eg, rheumatoid arthritis (RA), systemic lupus erythematosus (SLE)). The cause of autoimmune damage may be mainly due to either autoantibodies or autoimmune T lymphocytes.
