研究目的:

1)评估不同CLIA平台检测血浆生物标志物p-tau217和p-tau181在反映淀粉样蛋白PET(aβ-PET)状态分类准确性的相关性,对比单个标志物的检测性能,为优化临床检测方案提供参考; 2)对比APOE ε4蛋白检测与APOE基因分型的性能,评估在常规临床中应用ApoE4蛋白型免疫测定患者(考虑接受靶向淀粉样蛋白单抗治疗)的ApoE4状态的准确性和可行性。 3)构建并验证基于多模态数据(如MRI、PET、神经认知评估、生物标志物、检验指标等)的AD认知衰退预测模型,探索多模态数据在AD认知衰退预测中的协同效应,提高预测的准确性与个性化水平,为早期干预和个性化治疗提供理论依据。  

Objectives of Study:

To evaluate the correlation of plasma biomarkers p-tau217 and p-tau181 detected by different CLIA platforms in reflecting the classification accuracy of amyloid PET (Aβ-PET) status, compare the detection performance of individual biomarkers, and provide a reference for optimizing clinical testing protocols.To compare the performance of APOE ε4 protein detection and APOE genotyping, and assess the accuracy and feasibility of applying ApoE4 protein immunoassay for determining ApoE4 status in patients (who are candidates for targeted amyloid monoclonal antibody therapy) in routine clinical practice.To construct and validate an AD cognitive decline prediction model based on multimodal data (such as MRI, PET, neurocognitive assessment, biomarkers, laboratory indicators, etc.), explore the synergistic effect of multimodal data in predicting AD cognitive decline, improve the accuracy and personalization level of prediction, and provide a theoretical basis for early intervention and personalized treatment.
