A new blood test for Alzheimer's disease is up-to 94% accurate at predicting dementia before symptoms appear. The test's accuracy is increased when genetic predisposition and age are taken into account. The new test may eventually replace PET neuroimaging, currently considered the gold standard, for early detection of Alzheimer's.
A new blood test to detect biomarkers for Alzheimer's disease is set to undergo trials in the Fall. The test will be able to identify traces of amyloid beta in blood samples with a high degree of accuracy.
Neurofilament light protein in plasma may be a noninvasive biomarker for neurodegeneration associated with Alzheimer's disease.
