The causes of MS are not well understood and there are a number of factors to be considered. You may wonder whether you did something to cause your MS or if you could have stopped MS from happening to you. The answer is 'no'. No one could have advised you how to prevent your MS.
The cause of MS is a very active area of research and it seems likely that a number of different factors come together to trigger MS. Some of these factors are in the world around us and there is some evidence that lack of sunshine may play a part. Other possibilities include being exposed to certain common viruses and carrying certain genes. However, no one knows for certain.
Will my family get MS?
MS is not considered an inherited condition as it's not passed on in a predictable way like some conditions, such as haemophilia or muscular dystrophy. Most people have no previous family history of MS. Some genes make it more likely that someone develops MS but having these genes is definitely not enough on its own as other factors are needed to trigger the condition.
This means that the risk of other members of your family getting MS is small.
