There is no definitive answer to the question “what causes multiple sclerosis?”, but scientists believe it could be a combination of several factors. Researchers are working hard to help determine the cause of MS so that it can be better treated, prevented and of course at some point, cured.
We’ve put together a list of possible causes of multiple sclerosis with help from information from the National Multiple Sclerosis Society.
Researchers have found that the prevalence of MS is higher the further away from the equator you get, which has led them to believe that vitamin D (or a lack of it) may play a large role in the development of multiple sclerosis. Higher levels of vitamin D are thought to help support the immune system and reduce the risk of autoimmune diseases like MS.
Smoking has also been linked to multiple sclerosis in some studies and quitting smoking is thought to slow down the progression of the disease.
