Evolution and Comparative Analysis of Clinical Trials on Psilocybin in the Treatment of Psychopathologies: Trends in the EU and the US

Researchers are studying psilocybin, a compound from certain mushrooms, as a potential treatment for depression, anxiety, and addiction. The United States has significantly more clinical trials underway than the European Union, reflecting different regulatory approaches and funding levels. While US trials progress faster, EU trials emphasize safety and careful evaluation. Both regions show promising results when psilocybin is combined with professional psychological support in controlled settings.

Effect of psilocybin on marble burying in ICR mice: role of 5-HT1A receptors and implications for the treatment of obsessive-compulsive disorder

Researchers tested whether psilocybin mushrooms could help treat obsessive-compulsive disorder (OCD) using mice. They found that psilocybin reduced compulsive burying behavior in mice, similar to how approved OCD medications work. The study revealed that this anti-compulsive effect works through different brain mechanisms than previously thought, and that combining psilocybin with another drug called buspirone might block psychedelic effects while keeping therapeutic benefits.

How to account for hallucinations in the interpretation of the antidepressant effects of psychedelics: a translational framework

Psychedelic drugs like LSD and psilocybin show promise in treating depression with effects lasting months after single doses. However, scientists debate whether the hallucinations and mystical experiences these drugs produce are necessary for their healing effects. This review proposes a framework to test whether lower doses without hallucinations might still provide antidepressant benefits, similar to how anesthesia-administered ketamine works without the patient’s awareness.

The Effectiveness of Microdosed Psilocybin in the Treatment of Neuropsychiatric Lyme Disease: A Case Study

A 70-year-old man suffering from severe depression and anxiety caused by chronic Lyme disease and related tick-borne infections found relief after taking small doses of psilocybin mushrooms three times a week. Within days of starting treatment, his mood improved dramatically, and he remained symptom-free for two years. This case suggests that psilocybin’s ability to reduce inflammation in the brain may help patients with infectious-caused psychiatric conditions who cannot tolerate standard medications.
