An interesting brain imaging study suggests that cerebral blood flow recovery in the brain may be used as a a potential biomarker to determine the prognosis and outcomes of patients with concussions. "To our knowledge, this study provides the first prospective evidence of reduced CBF and subsequent recovery following concussion in a homogenous sample of collegiate football athletes and also demonstrates the potential of quantified CBF as an objective biomarker for concussion," the study concludes.
