Low Vitamin D Linked to Worse Recovery and More Falls After Stroke

Key Insight

This study suggests vitamin D levels may be a useful signal of recovery risk after a stroke.


Older stroke patients with atrial fibrillation were tested for vitamin D within two days of their stroke. Those with lower levels had worse physical recovery three months later, more depressive symptoms, and a higher chance of falling over the next year. About 60 percent of them were below 20 ng/mL. This is a snapshot in time, so it does not prove that low vitamin D caused the poorer outcomes.
