NCT ID NCT07764211
First seen Aug 13, 2026 · Last updated Aug 14, 2026 · Updated 1 time
Summary
This study follows 400 adults with generalized anxiety disorder (GAD) to understand how symptoms and health change over time. Researchers will collect clinical assessments, blood samples, and brain measurements at multiple visits. The goal is to identify factors that may predict symptom improvement, recurrence, and treatment outcomes. This could help develop more personalized approaches to diagnosing and managing GAD.
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 predict how anxiety symptoms change over time and support more personalized treatment plans.
- What could go wrong
- This is an observational study, so it cannot prove what causes changes in anxiety. Results may not apply to people outside this specific clinic group.
