Plasma Aβ42/Aβ40 predicts longitudinal amyloid pathology and clinical progression in amyloid-PET negative individuals with subjective cognitive decline

Early detection of amyloid-β (Aβ) pathology is critical for timely intervention in Alzheimer’s disease (AD). Changes in plasma Aβ42/Aβ40 levels appear early in the AD continuum, but whether they precede amyloid deposition detected by Aβ-PET requires further research. Data from 16...
