The role of biology
Women have a higher risk of developing multiple sclerosis than men, in fact, women are twice as likely to develop it than men. Northern European individuals with white ethnicities are the most commonly afflicted – much higher than any other race. Another risk factor is if a parent or sibling has had MS. Having a hereditary history of MS doesn’t necessarily mean you will develop the disease, but if you have a genetic predisposition and a family history of the disease, you could end up developing it. If you are a white, northern European woman, deficient in Vitamin D, and a heavy smoker with a history of MS in your family, you may not develop the disease, but you are at a significantly higher risk than the rest of the population.
It is important to keep in mind with MS, there is no single cause of the disease and if there is, it hasn’t been found yet. As research is currently being conducted and is ongoing, more insights into the cause of MS might begin to surface.
