Damage To Brains Of Vitamin D-Deficient Stroke Patients Is Far Greater

Stroke does the most brain damage when patients are deficient in vitamin D, a U.S. study shows. In addition, stroke patients with low vitamin D levels were found to be less likely than those with normal levels to have good outcomes in the three months following stroke. The area of dead tissue in the brains of vitamin D-deficient patients resulting from blood supply obstruction was about twice as large as in patients with normal levels. The findings apply equally to patients who suffer brain artery strokes (lacunar) and patients whose strokes are caused by carotid disease or a clot that originates somewhere else in the body (non-lacunar).
