Clinical Cohort of Memory Disorders
This is an observational study, meaning no treatment is given. Researchers at three Severance Hospital sites in Korea will collect a small blood sample, along with cognitive tests and brain scans, from about 1,550 people. They will bank the samples to look for blood markers of memory disorders. No phase applies. Nothing is being tested for effectiveness.
