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 T2 - Alzheimer’s Association International Conference CY - 27 Jul 2025 - 31 Jul 2025, Toronto (Canada) Y2 - 27 Jul 2025 - 31 Jul 2025 M2 - Toronto, Canada KW - Humans KW - Female KW - Male KW - Aged KW - Middle Aged KW - Alzheimer Disease: diagnosis KW - Alzheimer Disease: blood KW - Public Health KW - Aged, 80 and over KW - Biomarkers: blood KW - Sweden KW - Neuropsychological Tests KW - Surveys and Questionnaires KW - Telemedicine KW - Patient Selection KW - Biomarkers (NLM Chemicals) LB - PUB:(DE-HGF)1 ; PUB:(DE-HGF)16 C6 - pmid:41435182 C2 - pmc:PMC12726296 DO - DOI:10.1002/alz70860_106340 UR - https://pub.dzne.de/record/283077 ER -
