Alzheimer biomarkers

Amyloid, tau, neurodegeneration, imaging, CSF, and blood markers used to frame Alzheimer diagnosis, staging, and risk.

這是什麼

Alzheimer biomarkers are biological measurements used to frame whether Alzheimer-related brain changes are present and how the disease may be staged.[1]

為什麼重要

The 2024 criteria define Alzheimer disease biologically and incorporate core biomarkers, including imaging, CSF, and validated plasma approaches.[1]

它會影響哪些判斷

  • Biomarkers can support diagnosis, staging, and risk framing, but they do not replace clinical interpretation or predict the fate of a single neuron.[1,2]

解讀陷阱

  • The criteria state that clinical biomarker use is presently intended for symptomatic individuals and not for cognitively unimpaired people outside research contexts.[1]
