New research out of the Netherlands suggests that sun exposure, and not necessarily vitamin D, might be the key to easing common depressive and fatigue symptoms in multiple sclerosis.
To date, there has been much research whether vitamin D can prevent MS. Or, for those who already have MS, if vitamin D can slow the progression of the disease or help remit the disease or help reduce brain lesions.
However, no one has yet looked to see if vitamin D might help those with MS for some of the symptoms they suffer from, things like depression, anxiety, fatigue and cognitive impairment. Fatigue is the most common symptom of MS, with up to 92% of patients suffering from fatigue. Depression (40%), anxiety (20-40%) and cognitive impairment (40-70%) are common symptoms, too.
In this present study, researchers led by Dr Knippenberg of Maastricht University wanted to look at these very symptoms, and see if they correlated at all to vitamin D blood levels or sun exposure.
