We just published a paper in PNAS, showing microstructural changes to the hippocampus in aging and presymptomatic Alzheimer's disease - in humans, in vivo.

We continue to show the value of structural MRI beyond simply measuring large-scale atrophy!

🚨 Brain Age vs Direct Models in Alzheimer’s disease (AD) 🚨 A thread 🧵

1/ Brain age is a powerful indicator of general brain health, trained on massive datasets. But does this translate to better prediction for specific outcomes, like AD?
