Who these studies look for
Studies usually require a confirmed diagnosis and stable circumstances, and they monitor safety closely. If you are in crisis, contact a crisis line or emergency services rather than a study.
Matching a page like this one never means you qualify. Each research team decides eligibility at screening.
Questions
Will joining affect my current treatment?
Some studies require changes to medicines, which the study team manages; others add to your usual care. Talk to your own clinician before making any change.
