“A hidden Alzheimer’s tipping point may decide who gets dementia”
An Alzheimer’s threshold may influence who develops dementia
Key points
- 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.
