Longitudinal associations between blood‐based biomarkers of Alzheimer's disease and MRI‐measured cortical thickness and grey matter volume in subjective cognitive decline

Abstract

Background: Blood‐based biomarkers have been established as reliable markers of Alzheimer's disease (AD)‐related pathology in individuals with subjective cognitive decline (SCD). It remains unclear how these biomarkers and their longitudinal changes are associated with gray matter atrophy in SCD.
