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

7 Early Adulthood Neighborhood Conditions Linked to Midlife Cardiovascular Risk¶
Northwestern Medicine researchers found that adverse neighborhood conditions in early adulthood are associated with increased coronary artery calcification risk by midlife, according to a study published in Nature Communications. The research analyzed decades of data from the CARDIA longitudinal cohort using a neighborhood social determinants index measuring socioeconomic status, food access, physical activity opportunities, and local crime.

- Study published in Nature Communications using CARDIA longitudinal cohort data
- Index measures socioeconomic conditions, food access, activity opportunity, crime rates
- Coronary artery calcification is established early marker of cardiovascular disease
