Summary
This completed study looked at 210 cognitively normal older adults (ages 60-75) to see if sleep quality and race are linked to brain amyloid buildup, a marker of Alzheimer's risk. Participants wore sleep monitors and had brain scans over two years. The goal was to understand why African-Americans have higher Alzheimer's rates, not to test a treatment.
