What causes multiple sclerosis has long been debated, discussed, and argued. Since the 1800's the cause has evaded scientists, doctors, and researchers. But even though no single cause has ever been found, several keep showing up as the possible reason someone might develop MS.
The environment, genetics, a virus, and most recently hormones or the lack of them, have all been studied as the possible cause for multiple sclerosis. Vitamin deficiency, as in the case of B12 and D3, have both been implicated as well.
Stress and smoking are also possible causes in developing MS. There are recent studies implicating both, but the research for stress is weaker.
More than likely, the cause is a combination of two or more of the above factors. Possibly environmental and genetic or a virus that triggers the disease to develop in someone who is genetically susceptible.
