IONA Longitudinal Cohort Study
The IONA study is a long-term observational study based in Scotland, not a drug or treatment trial. Researchers are tracking memory, thinking skills, lifestyle factors, genetics, and biological markers in people aged 50 and older over many years. The goal is to understand how dementia develops and identify who may be at higher or lower risk. This is a data-gathering effort, not a test of any therapy.
