Five-Year Remission After Psilocybin Therapy for Depression: Quietly Durable Benefits in a Small Long-Term Follow-Up
A small, early long-term follow-up of psilocybin-assisted therapy for major depressive disorder suggests that the benefits can endure for five years. In the study, about two-thirds of participants who received two doses of psilocybin paired with psychotherapy remained in complete remission from depression five years later, with broad improvements in anxiety, functioning, and well-being. Yet the findings come from a limited, open-label follow-up of a single-trial cohort, underscoring both the promise and the caution needed when translating these results into wider practice. The new data offer a rare glimpse into the durability of psychedelic-assisted treatment, while highlighting the substantial questions that remain about who benefits most, how to scale such therapies responsibly, and how they might fit into Thailand’s mental health landscape.
