Description
Amirhossein Rabiei Rad and four co-authors, with a national Alzheimer's imaging initiative, present a 2025 study linking blood markers to shrinkage in the brain's memory hub. Blood tests for two tau related markers now promise early warning of Alzheimer's disease. How they tie to the fine subfields of the medial temporal lobe was unclear.
The team used data from 330 people with normal aging or mild thinking problems. They matched blood marker levels, and ratios between markers, with scan measures of each subfield's size. They also tested whether one marker carries the effect of another. The work aims to sharpen what a simple blood draw can say about brain change.
