"Researchers have studied a variety of possible causes for MS, and a combination of factors appears to be involved. A popular theory looks at commonly known slow-acting viruses (one that could remain dormant for many years), such as measles, herpes, human T-cell lymphoma, and Epstein-Barr. After being exposed to one of these viruses, some researchers theorize that MS may develop in genetically susceptible people. Research to identify the specific genes involved in MS is also ongoing.
Some scientists are looking for a connection between MS and nutritional factors, including fat intake, as well as deficiencies in fish oil and vitamin D. In addition to food and supplements, vitamin D is also derived from sunlight, which may be involved in the development of MS. As noted in the following section, populations living closer to the equator (and exposed to more sunlight) experience a lower incidence of MS." taken from

"Preliminary studies have suggested that a phenomenon called Chronic Cerebrospinal Venous Insufficiency (CCSVI), a reported abnormality in blood drainage from the brain and spinal cord, may contribute to nervous system damage in MS..." For more go to
