HISTORY OF MULTIPLE SELF‐REPORTED CONCUSSIONS IS NOT ASSOCIATED WITH REDUCED COGNITIVE ABILITIES
OBJECTIVE The long-term impact of sports-related concussion is uncertain . Several studies using traditional neuropsychological measures have found a relationship between a previous history of concussion and reduced cognitive abilities . In contrast , studies using computerized neuropsychological measures have typically found no relationship between concussion history and cognition . In the present study , we examined the association between a self-reported concussion history and cognition using traditional and computer-based neuropsychological tests . METHODS A computerized neuropsychological battery was administered to a sample of 858 collegiate male athletes . Of this sample , 298 athletes reported a history of concussion . A traditional neuropsychological battery was administered to a separate sample of 479 male collegiate athletes , 187 of whom reported a history of concussion . Finally , both a computerized and a traditional neuropsychological battery were administered to a third distinct sample of 175 male collegiate athletes , 57 of whom reported a history of concussion . Concussion history was assessed via self-report . None of the athletes had been concussed in the 6 months before testing . RESULTS No significant association was found between self-reported concussion history and performance on either  computerized or traditional neuropsychological tests .  CONCLUSION Findings suggest that athletes who report a distant history of concussion have minimal enduring neurocognitive deficits . Given conflicting findings in the literature , prospect i ve studies that attempt to identify moderating factors are necessary to help determine who is at risk for long-term cognitive difficulties after concussion
