Changes are occurring in the multiple sclerosis community. The disease, which has always been considered autoimmune, may be related to vascular problems, in which circulation in the cerebrospinal system is impaired, thereby preventing the proper drainage of venous blood from the brain. This timely book includes a history of MS, an explanation of autoimmunity, and examines the recent research relating to this new theory of MS and how the venous model compares to the standard model of the disease. It also offers practical suggestions for people with MS who wish to seek evaluation and possible treatment under the new model, as well as a chapter detailing experiences of some people who have recently received treatment.
