Here, we discuss strategies for recruiting a large and representative cohort, demographics and participant retention during the first study phase, and evaluate the process of implementing innovations enabling a fully remote study design.In April 2024, a recruitment campaign was launched in collaboration with a PR company to recruit at least 3000 participants between 50-80 years from the general population. Through an online study platform, participants were enrolled and asked to answer health and lifestyle questionnaires (Step 1), guided to remotely administered cognitive testing (Step 2; using the neotivTrials app or Cognitron battery), and blood sampling at any of the 105 public regional primary care units (Step 3; Figure 1). Additionally, optional remote blood sampling complemented the primary study protocol.At abstract submission, N = 6092 participants (mean age=63.9 years, 70 %B Alzheimer’s Association International Conference %C 27 Jul 2025 - 31 Jul 2025, Toronto (Canada) Y2 27 Jul 2025 - 31 Jul 2025 M2 Toronto, Canada %K Humans %K Female %K Male %K Aged %K Middle Aged %K Alzheimer Disease: diagnosis %K Alzheimer Disease: blood %K Public Health %K Aged, 80 and over %K Biomarkers: blood %K Sweden %K Neuropsychological Tests %K Surveys and Questionnaires %K Telemedicine %K Patient Selection %K Biomarkers (NLM Chemicals) %F PUB:(DE-HGF)1 ; PUB:(DE-HGF)16 %9 AbstractJournal Article %$ pmid:41435182 %2 pmc:PMC12726296 %R 10.1002/alz70860_106340 %U https://pub.dzne.de/record/283077
