Despite a great deal of research, it is still not known what causes MS. Here are some ideas about factors that could be involved in the causes:
MS seems to be more common in people who live farther from the equator. Another theory proposes that Decreased sunlight exposure and Vitamin D production may help cause MS
MS is not considered a hereditary disease however increasing scientific evidence suggests that genetics may play a role in determining a person’s susceptibility to MS.
Perhaps some sort of childhood illness can link to MS, but there is no reliable proof of any specific virus responsible for MS
