A Two-Year watch: can brain scans and surveys predict depression and anxiety in teens?
NCT ID NCT07744490
First seen Aug 04, 2026 · Last updated Aug 05, 2026 · Updated 1 time
Summary
This study follows 200 children and teens aged 7-17 who are at higher risk for depression, anxiety, or obsessive-compulsive disorder (OCD) due to family history or early symptoms. Over two years, researchers will use interviews, questionnaires, brain scans (EEG and MRI), and biological samples to track who develops these disorders and what factors might predict that. The goal is to identify early warning signs that could lead to better prevention and support for young people at risk.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could lead to better ways to identify children and teens at risk for depression, anxiety, or OCD before full-blown disorders develop, enabling earlier support and prevention.
- What could go wrong
- This is an observational study, not a treatment trial, so it won't directly test any intervention. The findings may not apply to all populations, and the two-year follow-up may be too short to capture all cases.

Who is studied
Approximately 200 children and adolescents aged 7-17 years who are at elevated risk for depressive disorders, anxiety disorders, or obsessive-compulsive disorder will be enrolled. Elevated risk is defined by a relevant family history or clinically significant subthreshold emotional or repetitive behavioral symptoms. Participants will not meet the full diagnostic criteria for the target disorders at baseline and will be followed prospectively for two years.
