Studies of concussed adults have identified neuronal and axonal injury and time-limited metabolic disruptions. An experimental animal model has also demonstrated physiologic perturbations, including reduced cerebral blood flow (CBF).
WHAT THIS STUDY ADDS:Using MRI techniques, we found no evidence of neuronal, axonal, or metabolic disruptions in 12 children with SRC. However, when compared with cont… Show more
