Risk Factors for Multiple Sclerosis (MS)
A risk factor is something that raises the chances of getting a health problem. A person can get MS with or without the risk factors listed below. The chances of getting MS are greater in people who have many risk factors.
MS is more common in people between the ages of 16 and 40. This is when MS is most often found. It is also more common in people of European descent.
Other things that may raise the risk are:
- Milk that has vitamin D added
- Cod liver oil
The sun also triggers a person's body to make vitamin D.
A viral infection may trigger MS. Researchers have been looking into human herpes virus-6 and Epstein-Barr virus. Some believe that it is the way some people respond to the virus that may trigger MS.
People who have had optic neuritis (inflammation of the optic nerve) have a high risk.
