Can we predict amyloid deposition by objective cognition and regional cerebral blood flow in patients with subjective cognitive decline?
Abstract
Subjective cognitive decline (SCD) may herald the first symptoms of Alzheimer s disease (AD) whereas individuals with beta‐amyloid (Aβ) deposition are regarded as a high‐risk group for AD. Recently, amyloid positron emission tomography (PET) studies have demonstrated clinical and cognitive feature differences between Aβ‐positive and negative SCD, but details of their differences remain unclear. We aimed to investigate the relationships among Aβ deposition, clinical, and cognitive features in patients with SCD.
