Summary
This study tests whether psilocybin, the active ingredient in magic mushrooms, can improve emotional wellbeing by promoting brain plasticity. Sixty adults with mild emotional decline will receive different doses of psilocybin, sometimes combined with a drug that causes temporary amnesia. Researchers will use brain scans and questionnaires to measure changes in mood and brain function.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Psilocybin
- What this could lead to
- If successful, this could help explain how psilocybin improves wellbeing by changing the brain, pointing toward new ways to treat emotional distress.
- What could go wrong
- This is an early Phase 1 study with only 60 people, so results may not apply broadly. The low dose and amnesia-inducing drug may limit effects.
