Why it matters
What
Researchers identified a biological shift between amyloid and tau pathology linked to progression from Alzheimer’s disease to dementia.
Why
Donor brain tissue showed microglia shifting from inflammatory to antigen-presenting states across disease stages.
Watch
Researchers may explore whether targeting microglial states at specific times can delay dementia.

Summary
- Researchers identified a biological shift linked to progression from Alzheimer's to dementia.
- Study used donor brain tissue across dementia, non-dementia, and centenarian groups.
- Six tissue domains revealed a critical transition between amyloid and tau pathology.
- Microglia shift from inflammatory to antigen-presenting states correlates with disease stages.
- Findings suggest therapies could target microglial states and timing to delay dementia.
