新研究显示,运动员重复头部受伤会导致血脑屏障持续泄漏, 增加CTE和阿尔茨海默病等大脑疾病的风险. Repetitive head injuries in athletes cause lasting blood-brain barrier leaks, raising risks for brain diseases like CTE and Alzheimer’s, new research shows.

一项新的研究将运动员重复头部受伤与持续漏血脑屏障联系起来, 即使是从橄球和拳击等接触体育比赛中退休多年之后. A new study links repetitive head injuries in athletes to a persistent leaky blood-brain barrier, even years after retiring from contact sports like rugby and boxing. 研究人员使用先进的MRI扫描和死后脑组织发现, 障碍物损伤使有害物质进入大脑, 与认知能力下降以及像中风性瘤和阿尔茨海默症等神经退行性疾病的增加风险相关. Using advanced MRI scans and postmortem brain tissue, researchers found that barrier damage allows harmful substances into the brain, correlating with cognitive decline and increased risk of neurodegenerative diseases like CTE and Alzheimer’s. 这些发现表明MRI扫描可以检测早期预警信号,从而可能进行预防性干预,并强调需要更广泛的研究和公共卫生行动,特别是对于年轻人和业余运动员. The findings suggest MRI scans could detect early warning signs, potentially enabling preventive interventions, and highlight the need for broader research and public health action, especially for young and amateur athletes.
