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 ...

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 ...

PET scan brain images show four distribution patterns (T1-T4) of the FDDNP signals that reflect different levels of abnormal brain proteins (tau and amyloid). According to researchers, the patterns ...

At first glance, it might appear that better access to so-called amyloid-PET scans could compensate for some of the racial inequities in Alzheimer’s disease, as Linda Goler Blount called for in a ...
