There are limited empirical data available regarding the relationship between concussion history and neurocognitive functioning in active National Football League (NFL) players in general and NFL draft picks in particular. Potential NFL draft picks undergo 2 neurocognitive tests at the National Invitational Camp (Scouting Combine) every year: the Wonderlic and, since 2011, the Immediate Post-concussion Assessment and Cognitive Testing (ImPACT). After conclusion of the combine and before the draft, NFL teams invite potential draft picks to their headquarters for individual visits where further assessment may occur.
To examine the relationship between concussion history and neurocognitive performance (ImPACT and Wonderlic) in a sample of elite NFL draft picks.
Cohort study; Level of evidence, 3.
Over 7 years, 226 potential draft picks were invited to visit a specific NFL team's headquarters after the combine. The athletes were divided into 3 groups based on self-reported concussion history: no prior concussions, 1 prior concussion, and 2 or more prior concussions. Neurocognitive measures of interest included Wonderlic scores (provided by the NFL team) and ImPACT composite scores (administered either at the combine or during a visit to the team headquarters). The relationship between concussion history and neurocognitive scores was assessed, as were the relationships among the 2 neurocognitive tests.
Concussion history had no relationship to neurocognitive performance on either the Wonderlic or ImPACT.
Concussion history did not affect performance on either neurocognitive test, suggesting that for this cohort, a history of concussion may not have adverse effects on neurocognitive functioning as measured by these 2 tests. This study reveals no correlation between concussion history and neurocognitive test scores (ImPACT, Wonderlic) in soon-to-be active NFL athletes.
关于脑震荡史与现役国家橄榄球联盟（NFL）球员，尤其是 NFL 选秀球员的神经认知功能之间的关系，目前仅有有限的实证数据。有潜力成为 NFL 选秀球员的人每年在国家邀请赛（侦察联合赛）上要接受 2 次神经认知测试：Wonderlic 测试，以及自 2011 年以来的即刻脑震荡后评估和认知测试（ImPACT）。在联合赛后、选秀前，NFL 球队邀请潜在的选秀球员到他们的总部进行个人访问，在此过程中可能会进行进一步评估。
在一组精英 NFL 选秀球员中，检查脑震荡史与神经认知表现（ImPACT 和 Wonderlic）之间的关系。
队列研究；证据水平，3 级。
在 7 年多的时间里，有 226 名潜在的选秀球员在联合赛后被邀请到一个特定的 NFL 球队总部进行访问。根据自我报告的脑震荡史，运动员被分为 3 组：无既往脑震荡史、1 次既往脑震荡史和 2 次或更多次既往脑震荡史。感兴趣的神经认知测量指标包括 Wonderlic 分数（由 NFL 球队提供）和 ImPACT 综合分数（在联合赛或球队总部访问期间进行）。评估了脑震荡史与神经认知分数之间的关系，以及这 2 种神经认知测试之间的关系。
脑震荡史与 Wonderlic 或 ImPACT 的神经认知表现均无关系。
脑震荡史并未影响这 2 种神经认知测试中的任何一种的表现，这表明对于这一队列，脑震荡史可能不会对这 2 种测试所测量的神经认知功能产生不良影响。本研究揭示了即将成为现役 NFL 运动员的脑震荡史与神经认知测试分数（ImPACT、Wonderlic）之间没有相关性。
