Magic mushroom compound targets Depression's blahs in small trial

NCT ID NCT06230757

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times

Summary

This small pilot study tested whether a single 25mg dose of psilocybin, given with psychological support, could help people with treatment-resistant depression who still struggle with anhedonia—the inability to feel pleasure or interest. Twenty adults took either the full dose or a very low 'active placebo' dose. Researchers measured changes in self-reported anhedonia scores over time. The study is already completed, and results may show whether this approach is worth testing in larger trials.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
psilocybin (a psychedelic compound)
What this could lead to
If it works, this could point toward a new way to treat the loss of pleasure and interest (anhedonia) that often doesn't improve with standard antidepressants.
What could go wrong
This is a very small pilot study with only 20 people, so results may not apply broadly. Psilocybin can cause intense psychological effects and is not yet approved for depression.
