Breakthrough Blood Test Shows Promise in Early Alzheimer's Detection.

Doctors are optimistic about a new blood test designed to detect Alzheimer's disease in its early stages, offering hope for accessible and affordable diagnosis. The test, utilizing a protein called phosphorylated tau 217 assay, demonstrates over 90% accuracy in diagnosing Alzheimer's before symptoms appear. This development eliminates the need for costly PET scans and invasive spinal fluid assessments, marking a significant step forward in Alzheimer's research and diagnosis.
