Psycho-affective健康、认知和神经生理学功能后体育运动员脑震荡的症状和无症状

提出正常恢复窗口concussive-injury 10 - 14天。然而,很大一部分运动员维持体育脑震荡症状(SRC)除此之外恢复窗口。对神经和神经生理差异在这些slow-to-recover运动员,这也许可以解释这些长期复苏时期。本研究旨在调查psycho-affective和神经心理症状和无症状的运动员最近经历了SRC。此外,我们这些有脑震荡的运动员与健康对照组相比,没有脑震荡的历史。因此,78名参与者的脑震荡(26症状,26日无症状)和26名健康对照组神经和神经心理学测试电池完成;包括贝克抑郁指数(BDI II)的情绪状态(盐)和后任务。此外,与事件相关脑电位(erp)是记录在一个实验性的古怪的范例。结果表明,运动员报告症状明显恶化水平的抑郁症状和负面情绪,改变运动员相比,无症状和控制。此外,有症状的运动员展示贫困后的性能测试,以增加委员会错误和较慢的反应时间。 Finally, ERP analyses revealed that both symptomatic and asymptomatic athletes demonstrated reduced allocation of attentional resources during the oddball task, indexed by reduced P3b amplitude. However, only asymptomatic athletes exhibited prolonged P3 latency indicative of delayed information processing. Taken together these results suggest that compared to asymptomatic and healthy athletes, athletes with persistent concussive-like symptoms not only report greater disruptions in affect and mood, but also demonstrate impaired cognitive and neurophysiologic function.
