Abstract: The paradigm for diagnosing and treating Alzheimer's disease(AD) is undergoing a profound transformation, moving towards a biomarker-driven and early-intervention-oriented stage. In diagnosis, the emergence of high-performance biomarkers such as plasma p-tau217 has significantly advanced the ultra-early detection of AD pathology, substantially shifting the diagnostic window forward.Meanwhile, multimodal molecular imaging techniques based on the ATN(VIS) biomarkers diagnosis framework, including amyloid β-protein(Aβ)-PET and tau-PET, enable in vivo visualization and typing of pathological burden, greatly enhancing diagnostic accuracy. The therapeutic field has also witnessed significant progress, with anti-Aβ monoclonal antibody drugs like Lecanemab and Donanemab receiving approval, demonstrating that disease-modifying therapy(DMT) targeting core pathology can effectively delay clinical decline. Current research has expanded to multiple pathological mechanisms, such as Aβ, tau and neuroinflammation, alongside active exploration of personalized combination therapy strategies. Future challenges lie in promoting the clinical translation and equitable application of these innovations to address the growing public health burden. This article systematically reviews the latest advancements in the field of biomarkers diagnosis and targeted therapy for AD, aiming to provide important references for establishing an early and precise diagnosis and treatment system and promoting clinical translation applications.

摘要: 阿尔茨海默病的诊断与治疗范式正处于深刻变革中,逐步迈向以生物学标志物为导向、早干预为核心的新阶段。诊断方面,血浆p-tau217等高性能生物学标志物的涌现推动阿尔茨海默病病理的超早期识别,使诊断窗口大幅前移;基于ATN(VIS)生物学标志物诊断框架的多模态分子影像学技术[如β-淀粉样蛋白(Aβ)-PET、tau-PET]实现对病理负荷的可视化与分型评估,显著提高诊断的准确性。治疗领域亦迎来重要进展,以仑卡奈单抗、多奈单抗为代表的抗Aβ单克隆抗体药物相继获批,证实针对核心病理的疾病修饰治疗可以有效延缓疾病进展。目前研究前沿已拓展至靶向Aβ、tau蛋白和神经炎症等多重病理环节,并积极探索个体化联合治疗策略。未来挑战在于推动这些创新成果的临床转化与普惠应用,以应对日益严峻的公共卫生负担。本文系统梳理阿尔茨海默病在生物学标志物诊断与靶向治疗领域的新进展,旨在为构建早期精准诊疗体系及推动临床转化应用提供重要参考。
