"Pre-Alzheimer's Silent Brain Changes Uncovered by Researchers"

A large study in China tracked middle-aged and older adults for 20 years, revealing that people who eventually developed Alzheimer's had higher levels of an Alzheimer's-linked protein in their spinal fluid 18 years prior to diagnosis. The study offers a timeline for how brain abnormalities associated with Alzheimer's pile up, providing potential insight for future interventions. The findings emphasize the importance of tracking silent brain changes for developing new therapies and preventions for Alzheimer's.
