Longitudinal study of the relationship between plasma amyloid-β1-42 and brain amyloid deposition

Takeaway

  • In this longitudinal study, low plasma amyloid-β1-42 levels were inversely associated with brain amyloid deposition in people with normal cognition.

Why this matters

    A blood test that predicts the extent of amyloid plaque deposition in the brain could provide earlier detection of those at higher risk of Alzheimer’s disease.
