Abstract
Introduction : Subjective cognitive decline (SCD) in amyloid-positive (Aβ+) indi-viduals was proposed as a clinical indicator of Stage 2 in the Alzheimer’s disease(AD) continuum, but this requires further validation across cultures, measures, andrecruitment strategies. Methods : Eight hundred twenty-one participants from SILCODE and DELCODEcohorts, including normal controls (NC) and individuals with SCD recruited from thecommunity or from memory clinics, underwent neuropsychological assessments overup to 6 years. Amyloid positivity was derived from positron emission tomography orplasma biomarkers. Global cognitive change was analyzed using linear mixed-effectsmodels. Results : In the combined and stratified cohorts, Aβ+ participants with SCD showedsteeper cognitive decline or diminished practice effects compared with NC or Aβ− par-ticipants with SCD. These findings were confirmed using different operationalizationsof SCD and amyloid positivity, and across different SCD recruitment settings. Discussion : Aβ+ individuals with SCD in German and Chinese populations showedgreater global cognitive decline and could be targeted for interventional trials.
