biomarkers in Alzheimer's disease

Biomarkers in Alzheimer's disease are measurable signs that indicate the presence or progression of the illness. They can include substances found in the blood, cerebrospinal fluid, or brain imaging results. Examples include low levels of the protein amyloid-beta and high levels of tau protein, both associated with Alzheimer’s. These biomarkers help doctors diagnose the disease earlier and more accurately, monitor its progression, and evaluate the effectiveness of treatments. Understanding biomarkers is crucial for advancing research and improving care for individuals with Alzheimer's disease.
