Alzheimer's disease, a type of dementia that profoundly alters a person’s memory and cognitive function, affects an estimated 6.7 million U.S. adults at least 65 years old, according to the ...

The results showed that patients with amyloid values of over 7.1 in their CSF had PET scans that mostly did not pick up anything abnormal—meaning they tested negative for Alzheimer's.

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 plasma p-tau217 levels and MK6420 Tau PET scans from them. Compared with p-tau217 assays, the VeraBIND assay was less specific and less sensitive at predicting a person’s amyloid status, ...

These proteins also form clumps in the brain, and their presence is more reliably associated with Alzheimer's disease than amyloid-beta clumps. Positron emission tomography (PET) scans are good at ...

Samsung C&T announced Thursday that its Life Science Fund, established in collaboration with Samsung Biologics, Samsung ...

Sex differences in tau may help explain why women face higher Alzheimer's dementia risk than men. At high levels of brain ...

Since amyloid-beta pathology often precedes tau ... labor and sensitivity. At present, tau-PET scans can pick up the signal from neurofibrillary tangles only when a large number are present ...
