背景情况:

血管痴呆症 (VaD) 的管理需要有效和特定的生物标志物.
对人类血液代谢的系统查对于识别VaD介质至关重要.

研究的目的:

系统地选人类血液代谢组,以寻找血管痴呆的潜在媒介.
通过两样本的门德尔随机化 (MR) 设计,识别用于VaD风险和管理的新型基于血液的生物标志物.

主要方法:

利用了3个代谢基因组全基因组关联研究 (GWASs) 与147,827名欧洲祖先的参与者.
采用两个样本的孟德尔随机化 (MR) 设计,并从血管痴呆症的欧洲血统GWAS (859例,211,300对照) 收集总结统计数据.
应用反变量加权MR和灵敏度分析来评估血液代谢物的因果作用.

主要成果:

基因决定型葡萄糖蛋白和O-甲基亚松酸盐与血管痴呆风险有负面关联.
基因决定的总胆固醇和低密度脂蛋白 (LDL) 胆固醇与血管痴呆风险有积极的关联.
灵敏度分析证实了这些关联的稳定性,没有检测到显著的定向向性.

结论:

葡萄糖蛋白,O-甲基酸盐,总胆固醇和LDL胆固醇是血管痴呆症的潜在血液生物标志物.

Dementia l: Introduction

Dementia l: Introduction

Dementia is an acquired, progressive syndrome characterized by a decline in multiple cognitive domains severe enough to impair daily functioning and reduce independence. Although memory loss is a central feature, the diagnosis requires additional deficits involving language, executive function, visuospatial skills, judgment, calculation, or abstract reasoning. These cognitive impairments reflect underlying neurodegenerative or vascular processes that gradually disrupt neuronal networks...
