Abstract

In this case-controlled study, PET scanning reflective of microglial activation and diffusion-tensor imaging assessing white matter integrity was performed on 14 National Football League players (four current, 10 retired) and compared to 16 matched controls, suggesting significant ongoing localized brain injury and repair along with subtle white matter changes in professional football players.
