Introduction: Vitamin D deficiency is now a well-recognized public health problem affecting almost every second person throughout the world. Recent evidence from many population-based studies has indicated that a poor vitamin D status is a predictor of future strokes. Materials and Methods: We reviewed recent studies on 25-hydroxyvitamin D [25(OH)D] and symptomatic ischemic stroke. A graded increase in the risk of symptomatic ischemic stroke with decreasing levels of plasma 25(OH)D has been found in most of the studies. Vitamin D also has a role in the poststroke period where its deficiency may hinder the rehabilitation process. Conclusions: After reviewing current literature on the subject, we conclude that there are some data to suggest the role of vitamin D in patients with stroke but it cannot be concluded as a risk factor for stroke. Larger population-based studies are needed to confirm the causative role of vitamin D in stroke.
