Functional, but minimal microstructural brain changes present in aging Canadian football league players years after retirement

This brain imaging study examined subjects with a history of repetitive concussive and sub-concussive impacts sustained over the course of their careers in the Canadian Football League (CFL). We hypothesized that microstructural and functional abnormalities, assessed using diffusion tensor imaging (DTI) and resting state functional magnetic resonance imaging (rsfMRI) respectively, would be present in these retired athletes, that are not present …
