Plasma Cystatin C and High-Density Lipoprotein Are Important Biomarkers of Alzheimer’s Disease and Vascular Dementia: A Cross-Sectional Study

Abstract

Plasma Cys C levels were higher in patients with AD/VaD than in healthy subjects.Plasma HDL levels were lower in patients with AD/VaD than in healthy subjects.Plasma Cys C levels were significantly correlated with dementia.The ROC curve for the combination of Cys C and HDL showed potential diagnostic value in distinguishing AD/VaD from healthy subjects.
