In a study of biomarkers in Alzheimer’s dementia, plasma p-tau217 had greater agreement with CSF and amyloid-PET biomarker ...

For the first time, scientists say, they have evidence that using a biologic drug to remove sticky beta amyloid plaques from ...

they were able to remove more amyloid from the brain. But other biomarker data is less clear. PET imaging scans, for example, didn’t show much of a difference in the amounts of tau protein in ...

These drugs work by clearing amyloid from the brain, which doctors can see on specialized imaging called a PET brain scan. Administered through a needle placed in an arm vein, these medications ...

Not the Same. In amyloid-negative people (left) few tangles accumulate over a decade. In amyloid-positives (right), tangles grow faster in women (red) than men (blue). [Courtesy of Gillian Coughlan, ...

Along with another protein, amyloid beta, tau can build up in the ... s because no single test is definitive. One exam, a tau PET scan, relies on a radioactive tracer injected into the body ...
