Lancaster MA, et al. - In this analysis, the researchers examined potential persisting effects of the injury, which serves as a follow-up to the previous work that reported white matter (WM) changes in the acute and subacute phase of sport-related concussion (SRC) recovery. For this investigation, concussed high school and collegiate football players and well-matched teammate controls were followed up at 6 months postinjury with diffusion tensor (DTI) and diffusion kurtosis imaging (DKI) as well as measures of self-reported symptoms, cognitive functioning, and balance. Results of this study suggested that DTI and DKI could be valuable tools in evaluating concussion severity, recovery, and possible long-term effects of a concussion.
