Alzheimer's disease biomarkers

Alzheimer's disease biomarkers are measurable indicators in the body that help diagnose and track the progression of the disease. These include proteins in the brain, such as amyloid-beta and tau, which can be detected through brain imaging or spinal fluid analysis. High levels of amyloid-beta suggest plaque buildup, while tau indicates tangles, both of which are characteristic of Alzheimer's. Detecting these biomarkers can aid in early diagnosis, allowing for timely treatment and better management of symptoms, even before significant cognitive decline occurs.
