Value of the biomarkers derived from cerebrospinal fluid in the diagnosis of Alzheimer disease / 中华检验医学杂志

ABSTRACT

Alzheimer disease (AD) is a neurodegenerative disease in the elderly. Early intervention is the only reliable means to delay the progress of the disease. Referring to the diagnostic criteria of AD, this paper summarizes and analyzes the representative literatures of various AD biomarkers derived from cerebrospinal fluid in recent years, and reviews the efficacy of various cerebrospinal fluid biomarkers in the diagnosis and differential diagnosis of AD. Results show that CSF Aβ42, Aβ42/Aβ40, T-tau, p-tau, Aβ42/p-tau, growth-associated protein 43, synaptosomal-associated protein 25, neurogranin and visinin-like protein-1 are of great value in the diagnosis and differential diagnosis of AD. The above CSF biomarkers can be used in the diagnosis and differential diagnosis of AD. The laboratory should select appropriate AD CSF biomarkers according to its own conditions in daily laboratory works.
