Can a blood test predict Alzheimer’s? New research shows the pTau217 biomarker detects amyloid accumulation and cognitive ...

How and Why a PET Scan Is Done and Possible Side Effects ...

A new study by investigators at Mass General Brigham has found that a blood test of plasma phosphorylated tau 217 (pTau217), an Alzheimer's disease biomarker, can predict the progression of amyloid ...

PET scans can detect amyloid plaques and tau tangles in the brain, which are often early signs of Alzheimer’s disease. But they’re not enough on their own to make a diagnosis. Alzheimer’s disease is ...

Tau proteins play an important role in our normal brain function, mainly by helping to stabilize neurons in the brain. But in Alzheimer’s disease, tau proteins can misfold and tangle inside neurons.

PET scans reveal amyloid plaques, which appear as warm colors such as red, yellow and orange. On the left is a patient with Alzheimer's disease, and on the right is a person with no detectable amyloid ...
