Traumatic brain injury is among the most common neurological disorders. Sports related injuries are a major cause of mild TBI among youth and young adults. We followed two ice hockey teams over a season and performed MRI and neuropsychological testing at pre-season and post-season and at serial timepoints following concussions. We measured changes in diffusion tensor imaging parameters using both a region of interest analysis and tract-based spatial statistics. We found evidence of brain structure changes in both concussed and non-concussed players.
