It is now recognized that repetitive head impacts (RHI) in sport have the potential for long-term neurological impairments. In order to identify targets for intervention and/or pharmacological treatment, it is necessary to characterize the neurobiological mechanisms associated with RHI. This review aims to summarize animal and human studies that specifically address Blood Brain Barrier (BBB) dysfunction, abnormal neuro-metabolic and neuro-inflammatory processes as well as Tau aggregation associated with RHI in collision sports. Additionally, we examine the influence of physical activity and genetics on outcomes of RHI, discuss methodological considerations, and provide suggestions for future directions of this burgeoning area of research.
现在人们已经认识到,运动中的重复性头部冲击(RHI)有可能造成长期的神经损伤。为了确定干预和/或药物治疗的靶点,有必要描述与 RHI 相关的神经生物学机制。本综述旨在总结专门针对碰撞运动中 RHI 相关的血脑屏障(BBB)功能障碍、异常神经代谢和神经炎症过程以及 Tau 聚集的动物和人类研究。此外,我们还研究了体育活动和遗传因素对 RHI 结果的影响,讨论了方法学方面的考虑,并为这一新兴研究领域提供了未来的发展方向。
