Summary in Seconds: Emerging research suggests that stress granules—tiny, stress-responsive structures inside cells—may play a central role in the early development of Alzheimer’s disease. Normally protective, these granules can persist abnormally in brain cells, disrupting protein balance, impairing cellular communication, and contributing to the buildup of toxic proteins like amyloid-beta and tau. Crucially, scientists believe this process may begin years before symptoms appear, opening the door to earlier detection and entirely new strategies for prevention and treatment. What if the earliest signs of Alzheimer’s disease appear long before memory loss begins—hidden deep within the cell? Recent research points to an
