Massachusetts General Hospital researchers developed an analysis method that can measure tau progression in Alzheimer's patients regardless of the stage they are in with the help of molecular PET measurements and found that tau signals first appear in the rhinal cortex, independently from beta-amyloid prior to spreading throughout the brain. The investigators used PET scans to measure tau signals of 443 adults, according to results published in Science Translational Medicine.
