专家反应:接触运动的头部敲门可能会损害年轻运动员的大脑

在运动运动迹象之前,在运动体育运动时被击中的年轻人可能会损害他们的大脑,这是对美式足球运动员的一项小型研究。慢性创伤性脑病(CTE)与头部重复命中有关,只能在死后诊断。但是,研究人员发现尚未患有这种疾病的足球运动员的大脑受到破坏,例如失去神经细胞和对血管的损害。他们建议,可能有一些方法可以早些发现该疾病,并强调了保护年轻运动员的重要性。

"This study used a powerful tool called single-nucleus RNA sequencing to examine how human brain cells respond to repetitive head impacts. The study authors examined brain cells from postmortem tissue from younger men (aged between 25 and 51) who had played contact sports, comparing three groups: eight healthy controls with little or no history of contact sports, nine athletes with a history of repetitive head impacts but no chronic traumatic encephalopathy (CTE)和11名在死后被诊断出患有早期CTE的运动员

“尽管对大脑捐赠研究的常见进行了检查,但该研究提供了对大脑对重复头部影响的反应的宝贵洞察力。该研究的重点是额叶皮层,这是CTE早期经常受到影响的领域,这是CTE早期影响的领域,但并未直接看着围绕血液的斑点病理学的斑点,因此,斑点的脑电图定义了,因此,斑点的病理越来越多,因此发现了一个斑点,因此发现了一个发现,从而发现了一群斑点。曝光

"The study shows that the repetitive head impact and CTE brains had fewer neurons within a specific cortical layer deep in the folds of the brain. This is the area most affected by shear stress during a head knock and the area where CTE lesions specifically develop. Importantly, the reduction in neuron number did not correlate with the amount of tau pathology in that region, suggesting that these changes happen early, before the established markers of CTE pathology appear.但是,数据还表明,个体之间的神经元数量差异很大,并且尚不清楚这些变化对大脑功能意味着什么

尚不清楚这些变化对脑功能 在一起,这些变化表明,即使没有CTE病理学,仅重复的头部影响也与炎症过程有关 上次更新:2025年9月17日2:22 pm 上次更新:
