Alharbi YR 2015 UL http://nsj.org.sa/content/20/4/329.abstract AB Multiple sclerosis (MS) is a common neurological disease, and its etiology remains unknown. In recent years, increasing attention has been paid to the possible association between MS and vitamin D deficiency. Here, we review the current literature between MS and vitamin D, showing clear evidence that vitamin D deficiency is a risk factor for MS despite the lack of direct evidence for the effects of vitamin D in MS progression.
