Summary
This study follows 2,500 people aged 10 and older with depression or bipolar depression over 10 years. Researchers collect data on symptoms, brain scans, genetics, and lifestyle to find patterns that predict how someone will respond to different treatments. No experimental drugs or therapies are given—the goal is to better understand depression and improve future care.
