血小板活动与阿尔茨海默病早期风险

from 生命哲学

此新闻稿概述了一项研究的发现,该研究表明对中年人进行血液血小板活性筛查可能有助于及早识别阿尔茨海默病的风险,为可能的预防性干预提供机会。研究人员发现,血管功能障碍中的血液凝血过程与中年人的阿尔茨海默病关键生物标志物有关,并指出血小板聚集是这种机制之一。该研究分析了“弗雷明汉心脏研究”中没有痴呆症的参与者的数据,并将他们的血小板聚集反应与阿尔茨海默病的PET 和 MRI 脑部标志物相关联。结果表明,血小板聚集更强的人往往大脑中淀粉样蛋白和 tau 蛋白水平也更高,这些都是阿尔茨海默病的特征。科学家们得出结论,循环血小板可能在症状出现前数十年就提供阿尔茨海默病风险的早期线索。前往小宇宙评论区与主播互动
