Summary:
- The article discusses a new study that provides a detailed timeline of how Alzheimer's disease progresses in the brain, showing that changes start as a trickle and then become a torrent.
- The study found that the first signs of Alzheimer's, such as the buildup of amyloid proteins, can begin 20 to 30 years before symptoms appear, and the disease then accelerates rapidly in the final stages.
- The findings suggest that early detection and intervention may be crucial for slowing the progression of Alzheimer's, and that targeting the disease in its earliest stages could be a more effective approach to treatment.
