The cause of MS is unknown for now, but scientists have discovered several factors that may contribute to MS. The possible factors are:
 * What causes multiple sclerosis?**
 * //Infectious (virus):// Some viruses are recognized as causing demyelination and inflammation, and it is possible that a virus or other infectious agent like bacteria triggers MS. Although many viruses and bacteria have been researched, none are found to have definitely triggered MS.
 * //Environmental//: MS is more common farther north or south of the Equator, like in Scandinavian areas, Northern Americas, Canada, and South America. Also, scientists think Vitamin D has something to do with MS. People living nearer to the equator get more sunlight year round, meaning more Vitamin D. Farther, they get less Vitamin D and sunlight.
 * //Genetics//: you have a higher chance of getting MS if a close relative has it, but it is not contagious or directly inherited. Also, certain genes in populations have higher chances of developing MS.
 * //Gender/age:// women get MS 2 to 3 times more often than men, and it usually occurs at ages 20 to 35, sometimes up to 40. It is possible to get MS when you're older or younger than that, but it is extremely rare, hence the name "Prime of Life disease".
