We analyzed data from 74 male collegiate hockey players. Each athlete's season began with a baseline administration of the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) neuropsychology test battery. Fourteen athletes sustained a sport-related head injury and were readministered the test to assess the impact of the injury. A significant decrease in performance (compared to baseline) on immediate and delayed word recall and designs followed the first concussion. Following a second sport-related concussion, the 4 affected athletes showed significant decrease in visual motor speed. Performance improved on 2 response speed measures (Ps < .01). More errors occurred during a visual processing/discrimination task and immediate recall of designs declined (Ps < .05). We discuss the results in light of recent work related to the impact of early-life concussions and head injury on late-life consequences, such as chronic traumatic encephalopathy, and more immediate issues such as return-to-play decisions for athletes.
我们分析了74名大学男子曲棍球运动员的数据。每位运动员的赛季开始时都进行了一次脑震荡后即刻评估和认知测试（ImPACT）神经心理学测试组合的基线测试。14名运动员遭受了与运动相关的头部损伤，并再次接受测试以评估损伤的影响。第一次脑震荡后，即刻和延迟单词回忆以及图案设计方面的表现（与基线相比）显著下降。第二次与运动相关的脑震荡后，4名受影响的运动员视觉运动速度显著下降。在两项反应速度测量中表现有所改善（P值<0.01）。在视觉处理/辨别任务中出现了更多错误，图案设计的即刻回忆能力下降（P值<0.05）。我们根据近期有关早年脑震荡和头部损伤对晚年后果（如慢性创伤性脑病）的影响以及运动员重返赛场决策等更直接问题的研究来讨论这些结果。
