Alternative therapy for neurological and psychiatric disorders using psilocybin

Psilocybin, when given under professional supervision, shows promise for treating difficult-to-treat conditions such as treatment-resistant depression, PTSD, anxiety, and substance dependence. In patients with treatment-resistant depression, a few doses significantly improved symptoms. For anxiety and PTSD, psilocybin reduced symptom intensity and improved emotional well-being. It also helped reduce addictions to alcohol and nicotine. The proposed mechanism is that psilocybin enhances brain connectivity, aiding trauma reprocessing and restructuring negative thought patterns. More research is needed to fully understand its mechanisms, effects, and risks.

Abstract

Introduction: In recent years, psilocybin has been explored as an alternative therapy for neurological and psychiatric disorders, such as depression, anxiety, post-traumatic stress disorder (PTSD), and substance dependence. Studies suggest that when administered under professional supervision, psilocybin can offer relief for patients with treatment-resistant disorders. Objective: The aim of this study was to analyze the therapeutic potential of psilocybin in treating difficult-to-treat conditions, including treatment-resistant depression, PTSD, anxiety, and substance dependence. Methods: A systematic review of clinical and experimental studies published in the past 5 years was conducted. The research was based on databases such as PubMed, Scopus, and SciELO, prioritizing studies on psilocybin in psychiatric disorder treatment. Randomized clinical trials, meta-analyses, and case studies were reviewed. Results: Studies showed that psilocybin positively affected patients with treatment-resistant depression, improving symptoms significantly with just a few doses. In patients with anxiety and PTSD, psilocybin reduced symptom intensity and improved emotional well-being. It also showed efficacy in reducing addictions such as alcohol and nicotine, offering new perspectives on addiction. The mechanisms of action suggest that psilocybin enhances brain connectivity, aiding in trauma reprocessing and restructuring negative thought patterns. Conclusion: Psilocybin is a promising alternative therapy for hard-to-treat disorders, including treatment-resistant depression, PTSD, and substance dependence. Administered under professional supervision, it offers benefits and a favorable safety profile. However, more research is required to understand its mechanisms, effects, and risks.
