Clinical Cohort of Memory Disorders

Sponsor: Yonsei University

Summary

This observational study is designed as a multicenter clinical cohort to collect and bank blood specimens linked to clinical and brain imaging data for biomarker discovery and validation in memory disorders. The protocol lists Severance Hospital, Gangnam Severance Hospital, and Yongin Severance Hospital as study sites. Planned enrollment is 1,550 participants: 1,500 adults aged 50 years or older and 50 healthy young adult controls aged 19-30 years. Participants are enrolled according to eligibility criteria and consent, irrespective of the specific medication received. Clinical information, cognitive assessments, and available brain magnetic resonance imaging (MRI) and positron emission tomography (PET) data will be collected to investigate diagnosis, disease severity, and clinical course. A total of 6 mL of research blood will be collected for banking, separated into plasma and buffy coat, and stored at -70°C. Young adult controls will provide a comparison for age-related and disease-related biomarker differences. The target follow-up duration for the memory disorder cohort is 5 years; young adult controls attend a single study visit. The overall study period is 120 months from IRB approval.
