Brain study reveals secrets of placebo effect in depression

NCT ID NCT02562430

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study looked at why some people with depression feel better after taking a placebo (a sugar pill with no active drug). Researchers used brain scans and other tests to find biological markers linked to this placebo response. The goal is to improve future depression treatments and clinical trials by understanding how the brain's own healing mechanisms work.
