A team of researchers at the USC Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC has identified important differences in how early ...

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 ...

Dr. Gary Small answers the question: 'MRI, PET Scan for Alzheimer's Diagnosis?' May 4, 2009 -- Question: When are imaging diagnostics, such as an MRI or PET scan, used to determine whether I have ...

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 ...

Professor of Medical Imaging at the University of Arizona Lars Furenlid, the project’s lead researcher. Professor of Radiology at UMass Chan Medical School Michael King. In order to better study and ...

NEW ORLEANS (June 23, 2025)—A novel PET imaging approach has revealed distinct patterns of brain inflammation in patients with progressive apraxia of speech (PAOS), a rare neurodegenerative disorder ...

Routine brain scans are starting to reveal something that was invisible to doctors a decade ago: subtle structural changes that may foreshadow Alzheimer’s disease long before memory tests fail.

Biologically speaking, there is no organ as vital or complex as the brain. And yet, the brain still remains somewhat a of a mystery—there’s a lot that even experts don’t know. Another troubling fact ...

USC researchers have found a promising new brain scan marker that could better detect Alzheimer’s risk — but only for some. The tau-based benchmark works in Hispanic and White populations when paired ...

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.
