Biomarkers for Alzheimer's

Biomarkers for Alzheimer's are measurable indicators in the body that signal the presence or risk of the disease. They often come from tests analyzing cerebrospinal fluid, blood, or brain imaging, and can detect abnormal protein build-up like amyloid plaques and tau tangles, which are characteristic of Alzheimer's. These markers help doctors diagnose the disease earlier, monitor its progression, and evaluate treatment effectiveness, often before significant memory loss occurs. Overall, biomarkers provide valuable insights into Alzheimer's at a molecular level, improving early detection and personalized care.
