Brief Summary

Multiple sclerosis (MS) is a disease of the nervous system. The exact cause of MS is unknown, but it is believed to be an autoimmune condition. Autoimmune conditions are diseases that cause the body's immune system and natural defenses to attack healthy cells. In the case of MS, the immune system begins attacking myelin, the cells that make up the sheath covering nerves. Without myelin, nerves are unable to transmit signals effectively and symptoms occur. This study is directed toward a better understanding of the cause of Multiple Sclerosis (MS). Researchers will evaluate patients with a tentative diagnosis of MS or other neurological diseases possibly caused by a immunological reaction. Patients will undergo a series of three MRIs, taken once a month for three months and submit blood samples for immunological studies.
