摘要 阿尔茨海默病(ad)是一种以痴呆为主要特征的渐进性神经变性疾病,除不到1%的患者为家族遗传性者外,决大多数为散发的起病年龄超过65岁的老年期ad.ad的患病率随着年龄的增加而上升,70岁以上人群中约占10%;85岁以上则达25% ~45%.对ad正确而合理的治疗依靠准确的诊断.ad的诊断目前主要还是依赖于临床对痴呆症状的评估,但是随着对ad发病机制和特征的认识的越来越明确和深入,对ad的诊断也不断在进步,也提出了更高的、更规范的要求,需要有更为客观的生物标记物的支持.本文主要就目前已基本得到认可的ad生物标记物,如β淀粉样蛋白42( aβ42)、总的微管相关蛋白( t-tau)和磷酸化微管相关蛋白(p-tau)的检测技术及进展进行综述.
