Sun Exposure During Teenage Years May Affect MS Development

October 8, 2015

Danish researchers report that people with MS who spent time in the sun every day during the summer as teens developed MS later than those who did not. The investigators ruled out other possible genetic and lifestyle factors. This study lends more evidence to the role of vitamin D in MS development; the National MS Society is funding a clinical trial to determine whether vitamin D supplements can slow MS activity in people who already have the disease.

About Multiple Sclerosis

Multiple sclerosis is an unpredictable, often disabling disease of the central nervous system that disrupts the flow of information within the brain, and between the brain and body. Symptoms range from numbness and tingling to blindness and paralysis. The progress, severity and specific symptoms of MS in any one person cannot yet be predicted, but advances in research and treatment are leading to better understanding and moving us closer to a world free of MS. Most people with MS are diagnosed between the ages of 20 and 50, with at least two to three times more women than men being diagnosed with the disease. MS affects more than 2.3 million people worldwide.
