据估计,到 2050 年,全球阿尔茨海默病 (AD) 患者的数量将从目前的 3600 万人增加四倍。迄今为止,在尸检之前,还没有任何一项测试可以确认一个人患有AD。因此,迫切需要准确、灵敏的 AD 早期诊断工具。 AD 的复杂病因和多种发病机制要求对当前可用的生物标志物进行系统级理解,并通过基于网络的异构数据类型建模来研究新的生物标志物。在这篇综述中,我们总结了将 AD 作为连通性综合征进行研究的最新研究。我们认为,基于网络的生物标志物发现方法将为充分理解网络退化假说(疾病在特定网络区域开始并逐渐扩散到初始位点网络的连接区域)提供关键见解,对早期诊断和疾病缓解治疗具有潜在影响。我们引入了一种新的生物标志物定量研究框架,有助于缩短 AD 学术研究和临床诊断之间的过渡。
By 2050 it is estimated that the number of worldwide Alzheimer’s disease (AD) patients will quadruple from the current number of 36 million people. To date, no single test, prior to postmortem examination, can confirm that a person suffers from AD. Therefore, there is a strong need for accurate and sensitive tools for the early diagnoses of AD. The complex etiology and multiple pathogenesis of AD call for a system-level understanding of the currently available biomarkers and the study of new biomarkers via network-based modeling of heterogeneous data types. In this review, we summarize recent research on the study of AD as a connectivity syndrome. We argue that a network-based approach in biomarker discovery will provide key insights to fully understand the network degeneration hypothesis (disease starts in specific network areas and progressively spreads to connected areas of the initial loci-networks) with a potential impact for early diagnosis and disease-modifying treatments. We introduce a new framework for the quantitative study of biomarkers that can help shorten the transition between academic research and clinical diagnosis in AD.
