In the first comparative study to examine cognitively healthy footballers at both college- and career-level, researchers investigated the long-term impacts of concussion on players. While most previous research into football-based head impacts has focused on cognitively impaired footballers; the study at University of North Carolina at Chapel Hill (NC, USA), published in the journal Radiology, compared the neuroimaging of former players with no evidence of cognitive impairment, to analyze the effects that differing playing histories and exposure to concussion could have later in life.
