AI Unmasks 40-Gene Shield Against Alzheimer’s Decline
TL;DR Summary
AI analysis across normal and Alzheimer’s brains identified a precise 40-gene signature that predicts cognitive resilience despite full pathology, outperforming prior signatures. Mouse studies linked Chromogranin A (CgA) to protection against memory decline and tau tangles, with sex-specific effects, suggesting that therapies targeting CgA-centered pathways could boost cognitive resilience before symptoms appear rather than focusing on clearing plaques after damage.
