Participants were memory clinic patients with variable baseline cognitive stage, ranging from SCD+ to MCI and dementia, enrolled from 8 European memory clinics. Enrollment strategies have been described in a previous article.Participants were enrolled from 8 European academic memory clinics: University and University Hospital of Geneva (Geneva, Switzerland), Amsterdam University Medical Center, Location VUmc (Amsterdam UMC; Amsterdam, the Netherlands), Centre Hospitalier Universitaire de Toulouse (CHUT; Toulouse, France), Barcelonaβeta Brain Research Center (Barcelona, Spain), University of Cologne (Cologne, Germany), University College London (UCL; London, United Kingdom), Karolinska Institutet (Stockholm, Sweden), and Centre Hospitalier Universitaire Vaudois (Lausanne, Switzerland). Three academic memory clinics (Amsterdam UMC, CHUT, and UCL) extended the recruitment to external nonacademic partnering memory clinics.Ethnicity data were collected by members of the AMYPAD-DPMS study team at the local recruiting memory clinics, who chose among options on an electronic case report form. The options were African, Asian or Asian British, Black or Black British, British, Caribbean, Chinese, Indian, Irish, multiracial (listed as “mixed”), Pakistani, White, White and Black African, White and Black Caribbean, any other Asian background, any other multiracial background, any other White background, and not stated. Subsequently, numbers of participants identified as British, Irish, White, and any other White background were grouped into a White category for reporting baseline characteristics because of the small numbers in each ethnic group.Major inclusion and exclusion criteria are reported in detail in the eMethods in
