Inflection points and transitions in Alzheimer’s disease
Abstract Alzheimer’s disease is widely depicted as a linear cascade from amyloid-β accumulation to Tau pathology and neurodegeneration. We propose instead that the disease unfolds through discrete molecular, cellular and network phases organized around biological inflection points. At these thresholds, stress-driven loss of homeostasis produces qualitative shifts in cellular behavior that alters disease progression.

Human microglial transitions at the Aβ–tau inflection point associate with divergent pathways to dementia and resilience
|
Abstract Alzheimer’s disease (AD) is not an inevitable outcome of pathology but a dynamic process shaped by how brain cells respond to amyloid-β (Aβ) and tau. To disentangle these responses, we combined spatial transcriptomics and single-nucleus RNA sequencing of the superior frontal cortex from octogenarians living with or without dementia and from cognitively intact centenarians with comparable Aβ accumulation.
