8Risk Factors for MS Relapses
Some major risk factors for the development of MS relapses include:
– Hormones, particularly reproductive hormones, may affect the risk of a MS relapse. For instance, it has been shown that high estrogen levels may reduce the risk. That’s why women tend to experience fewer relapses when they are pregnant.
– Age: The risk is higher in adults over 50 years old than in younger people. This may be mainly due to age-related inflammation.
– Vitamin D: A deficiency of vitamin D may increase the risk of a MS relapse.
– Infections: Both viral and bacterial infections may increase the risk of an MS relapse.
– Genetics: Certain genetic factors may increase the frequency of MS relapses. [8]
