Neuroscience Research¶
7.5 Alzheimer's brain changes detected years before amyloid plaques appear¶
A 20-year longitudinal study of healthy older adults found structural brain changes occurring at least seven years before amyloid plaques become detectable by PET scans. The research, published in Nature Neuroscience, suggests disease processes in Alzheimer's may begin far earlier than current imaging can detect, enabling earlier disease identification.
- Structural brain changes detected 7+ years before amyloid plaques appear
- Study tracked healthy older adults over nearly 20 years
- Published in Nature Neuroscience
- Changes detected in cognitively normal individuals
- Earliest signal detected on brain scans to date
