Tau markers
WebAug 18, 2024 · Scientists have been examining whether another form of the tau protein, called ptau217, can also serve as an early marker of Alzheimer’s development. Both are found in the tau tangles that accumulate in the brain and can spill into the bloodstream. Two new studies tested different ways of measuring ptau217 in blood samples. WebDec 7, 2024 · Additionally, spatial reasoning was related to elevated entorhinal tau, inferior temporal tau, and neocortical amyloid. Given the observed cognitive heterogeneity in early stages of AD, we explored the relationship between different aspects of digital clock performance and amyloid and tau pathology across the cortical surface.
