Traumatic brain injury (TBI) is an independent risk factor for stroke, according to a review published online April 4 in the International Journal of Stroke.
Grace M. Turner, Ph.D., from the University of Birmingham in the United Kingdom, and colleagues conducted a systematic literature review to examine the association between TBI and stroke risk.
Based on 18 included studies (2,606,379 participants from four countries), the researchers found that TBI patients had a significantly increased risk for stroke versus controls (pooled hazard ratio, 1.86). Stroke risk may be highest in the first four months post-TBI but can remain significantly elevated up to five years post-TBI.
