CUHK Brain Health Longitudinal Study
This is a long-term observational study at the Chinese University of Hong Kong that is tracking people with brain diseases, people at high risk for them, and healthy volunteers over time. Researchers are collecting questionnaires, medical records, and phone interviews to identify what risk factors lead to stroke, dementia, and other brain conditions. There is no drug or device being tested — this is a data-gathering study, with no phase designation.
