This review examines how psilocybin, a compound found in certain mushrooms, may help people recover from traumatic brain injuries. The research suggests that psilocybin could reduce harmful inflammation in the brain, help the brain form new connections to compensate for damage, and improve mood and depression commonly experienced after brain injuries. While promising, the authors emphasize that more clinical trials are needed to confirm safety and effectiveness before psilocybin can be used to treat brain injury patients.
