Alzheimer's Diagnosis: Blood Test Breakthrough
Early Detection and Improved Accuracy
A significant advancement towards the diagnosis of Alzheimer's disease through a simple blood test has been made by scientists. Researchers reported on Sunday that new blood tests may allow doctors to determine Alzheimer's disease with greater speed and accuracy, aiding in the early detection and treatment of this neurodegenerative disorder.
Ptau-217 and APS2 Blood Tests
The ptau-217 blood test, one of the new developments, demonstrated comparable accuracy to FDA-approved cerebrospinal fluid tests in detecting amyloid buildup, a protein implicated in Alzheimer's. Additionally, the amyloid probability score 2 (APS2) test achieved 91% accuracy in diagnosing Alzheimer's disease in individuals with mild cognitive decline or memory difficulties.
