    Background and Objectives: Cross-sectional studies suggest marked dopamine (DA) decline in aging, but longitudinal evidence is lacking. The aim of this study was to estimate within-person decline rates for DA D2-like receptors (DRD2) in aging, and examine factors that may contribute to individual differences in DRD2 decline rates. Methods: We investigated 5-year within-person changes in DRD2…
