关于儿童和青少年脑震荡的持续影响的现有文献有限且参差不齐，对于患者、临床医生、研究人员或政策制定者来说，还没有明确的答案。这项研究的目的是检查过去的脑震荡是否对青少年运动员有持续的影响。这项研究的参与者包括 643 名年龄在 13 至 17 岁之间的矮脚和侏儒曲棍球运动员（按比赛划分，最优秀的占 20%）（平均年龄 = 15.5，SD = 1.2）。使用季前调查问卷（PSQ）回顾性记录基线评估时的脑震荡历史，该问卷由父母和球员在基线测试之前在家中完成。以英语作为第二语言、自我报告的注意力或学习障碍、基线 6 个月内脑震荡或疑似无效测试资料的玩家被排除在这些分析之外。对五种复合/领域的人口统计调整标准分数以及来自简短的脑震荡后立即评估和认知测试 (ImPACT) 计算机化电池的原始症状评级进行了分析。之前有过一次或两次或多次脑震荡的青少年运动员在 ImPACT 上的神经认知功能并不比没有脑震荡的青少年运动员明显更差。与没有或一次脑震荡的患者相比，有两次或两次以上脑震荡的患者报告的症状明显更多。曾多次遭受脑震荡的青少年的基线症状水平较高，但使用这种简短的计算机化电池后，神经认知功能没有组间差异。
The existing literature on lingering effects from concussions in children and adolescents is limited and mixed, and there are no clear answers for patients, clinicians, researchers, or policy makers. The purpose of this study was to examine whether there are lingering effects of past concussions in adolescent athletes. Participants in this study included 643 competitive Bantam and Midget hockey players (most elite 20% by division of play) between 13 and 17 years of age (mean age = 15.5, SD = 1.2). Concussion history at baseline assessment was retrospectively documented using a pre-season questionnaire (PSQ), which was completed at home by parents and players in advance of baseline testing. Players with English as a second language, self-reported attention or learning disorders, a concussion within 6 months of baseline, or suspected invalid test profiles were excluded from these analyses. Demographically adjusted standard scores for the five composites/domains and raw symptom ratings from the brief Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) computerized battery were analyzed. Adolescent athletes with one or two or more prior concussions did not have significantly worse neurocognitive functioning on ImPACT than did those with no previous concussions. There were significantly more symptoms reported in those with two or more prior concussions than in those with no or one prior concussion. Adolescents with multiple previous concussions had higher levels of baseline symptoms, but there were not group differences in neurocognitive functioning using this brief computerized battery.
