Psilocybin-assisted therapy is emerging as a promising approach for depression, particularly treatment-resistant cases where standard antidepressants show limited efficacy and burdensome side effects. Research suggests psilocybin can produce rapid and sustained reductions in depressive symptoms, partly by enhancing neuroplasticity and facilitating meaningful psychological experiences. When embedded in a structured therapeutic model with preparation, dosing, and integration sessions, psilocybin may foster emotional openness, cognitive flexibility, and long-term positive change, highlighting a potential paradigm shift in how depression is treated within modern clinical research frameworks.
