Tau proteins play an important role in Alzheimer's disease. Tau helps to stabilize neurons in the brain, but in Alzheimer's disease, tau proteins can misfold and tangle inside neurons. These tangles ...

Researchers use AI and postmortem tissue to reveal that tau PET scans are often influenced by iron and neuroinflammation rather than tau tangles alone.
