Tau tracers track first emergence of tangles in familial Alzheimer's

PET imaging transformed Alzheimer’s research when it enabled scientists to track the spread of Aß pathology in living people. It revealed that amyloid plaques appear decades before symptoms of Alzheimer’s disease emerge. But what about neurofibrillary tangles?
