目的：确定运动性脑震荡后神经心理和电生理功能是否存在年龄差异。设计：横断面研究。参与者：96名运动员（9-12岁，n = 32; 13-16岁，n = 34;成人，n = 30），其中一半患有运动性脑震荡。认知功能进行了评估，使用标准化的神经心理学测试和事件相关电位引起的视觉3刺激oddball范式。PCSS用于评估受伤时的症状。主要结果测量：神经心理学评估与国家曲棍球联盟使用的电池的适应。P3 a和P3 b的波幅和波幅按组（脑震荡组与对照组）和年龄进行分析。结果：所有脑震荡运动员的P3 b波幅均显著低于其未受伤的队友（p > 0.05）。结论：这些数据表明脑震荡后至少6个月存在持续的神经生理缺陷。此外，青少年对脑震荡的后果比儿童或成人更敏感。
Objective: To determine whether age differences exist with respect to neuropsychological and electrophysiological functioning following a sport concussion.Design: Cross-sectional study.Participants: Ninety-six athletes (9-12 years, n = 32; 13-16 years, n = 34; adults, n = 30), half of whom had a sport concussion.Intervention: Cognitive functioning was assessed using standardized neuropsychological tests and event-related potentials elicited by a visual 3-stimulus oddball paradigm. The PCSS was used to assess symptoms experienced at the time of injury. Main outcome measurements: Neuropsychological assessment with an adaptation of the battery used by the National Hockey League. Latencies and amplitudes of the P3a and P3b were analysed in terms of group (concussed vs. control) and age.Results: All concussed athletes had significantly lower amplitude for the P3b component compared to their non-injured teammates (p > 0.05). Adolescents also showed persistent deficits in working memory (p > 0.05).Conclusions: These data suggest persistent neurophysiological deficits that are present at least 6 months following a concussion. Moreover, adolescents are more sensitive to the consequences of concussions than are children or adults.
