Summary in Seconds: New research points to stress granules—tiny, normally protective structures inside cells—as a potential early driver of Alzheimer’s disease. When these granules persist longer than they should, they may disrupt essential cellular functions, promote the buildup of toxic proteins, and quietly set the stage for disease years before symptoms appear—offering a promising new path toward earlier detection and intervention. The Path Forward: From Cellular Clues to Real-World Impact If stress granules are indeed early drivers of Alzheimer’s disease, the implications are profound. What began as a cellular curiosity is now shaping into a promising frontier for early detection,
