Abstract
The early identification of Alzheimer’s disease requires efficient and non-invasive detection methods. Plasma biomarkers, with their convenient sampling, repeatable detection, and suitability for large-scale application, have become core elements in the construction of auxiliary diagnostic models. Indicators such as β-amyloid-related ratios, phosphorylated tau181, phosphorylated tau217, neurofilament light chain, and glial fibrillary acidic protein in plasma can stably reflect the core pathological processes in the brain. The diagnostic efficacy of single-indicator and multi-indicator combined models continues to improve. The correlation between plasma biomarkers and changes in brain structure and function, as well as cognitive assessment, is becoming increasingly clear, driving the development of auxiliary diagnostic models towards precision and intelligence. This provides stable support for early screening, risk stratification, and disease progression monitoring.
