What causes MS?

No one knows what causes MS.  There are a lot of theories but no true answers.  For years, doctors have looked at many possible causes, including environmental factors, viral infections, dietary factors, and genetics. While that research has yielded a lot of valuable information, we still can’t determine a cause.  The current thinking is that a combination of these factors causes MS—which would explain why it’s proving so difficult to figure out.  To give you a sense of the complexity of this problem, here are a few interesting facts:  MS occurs two to three times more in women than men.  It is most common in Caucasians and people with Northern European heritage, but in no way limited to those populations—especially as there is more inter-culture marriage.  People who grew up in colder, temperate climates are as much as five times more likely to develop MS.  Recent studies have suggested that Vitamin D play an important role.  In short, it’s a mystery we are still trying to figure out.
