2025年的一项研究发现,即使没有CTE,参加接触体育运动的年轻运动员也会因头部撞击而脑细胞丧失和受损。 Young athletes in contact sports suffer brain cell loss and damage from head impacts, even without CTE, a 2025 study finds.

根据"自然"杂志于2025年9月17日发表的一项研究,足球,足球和冰球等接触运动中的年轻运动员在不经心脑损伤的情况下,也会因重复撞击头部而遭受严重的脑细胞损失,炎症和血管损伤. A September 17, 2025, study in Nature finds that young athletes in contact sports like football, soccer, and ice hockey suffer significant brain cell loss, inflammation, and blood vessel damage from repeated head impacts—even without developing CTE. 研究人员对年龄在25至51岁的28名男子的脑组织进行了分析,发现在易受冲击的脑区域,56%的神经元损失,以及免疫活动和结构变化加剧,表明大脑早期受伤。 Analyzing brain tissue from 28 men aged 25 to 51, researchers found a 56% neuron loss in impact-vulnerable brain regions, along with heightened immune activity and structural changes, suggesting early brain injury. 由波士顿大学的Jonathan Cherry领导并由NIH资助的研究结果表明,这种损害可能比以前想象的早许多年就开始了,突出表明需要改进探测和预防战略,以保护年轻运动员免受长期神经风险。 The findings, led by Jonathan Cherry of Boston University and funded by the NIH, indicate such damage may begin years earlier than previously thought, underscoring the need for improved detection and prevention strategies to protect young athletes from long-term neurological risks.
