Psilocybin has demonstrated promise for improving depressive symptoms in treatment-resistant depression, but its effects on anxiety, quality of life, functioning, and posttraumatic stress symptoms are less well studied. This study reports exploratory findings from an open-label trial in Veterans with TRD. Participants received a single 25-mg dose of psilocybin administered with psychological...

A single dose of psilocybin may provide rapid relief for people with major depressive disorder (MDD), with benefits emerging within days and lasting for several weeks, according to a randomized clinical trial published May 15 in JAMA Network Open . Researchers of the study, “Short‐Term and Late‐Term Effects of Psilocybin on Symptoms in Major Depression: A Randomized Clinical Trial,” found that...

BACKGROUND: Several recent trials indicate positive effects of psilocybin in patients with major depressive disorder. However, questions need to be addressed regarding the relationship between dosage and therapeutic outcomes, such as the recommended dose range and frequency for optimal practice as well as the dose-dependent adverse effects. OBJECTIVE: (1) to assess the effectiveness and...

Psilocybin shows encouraging outcomes for patients with cancer and major depressive disorder (MDD). However, there is insufficient evidence on the use of evidence-based psychotherapeutic interventions to consistently guide and standardize psilocybin preparation, dosing, and integration. Meaning-centered psychotherapy (MCP) is a manualized, brief psychotherapeutic intervention that enhances...

Psilocybin shows promise for treatment-resistant depression (TRD), but long-term data are limited. This study examined the antidepressant effect of one or two psilocybin doses with adjunct psychotherapy in TRD until twelve months. This is a naturalistic follow-up of a phase 2b, randomized, active placebo-controlled trial, where participants were randomized to receive two drug administrations...

Importance: Psilocybin has been proposed as a rapid-acting antidepressant (onset 6 weeks), but evidence from randomized clinical trials remains limited, particularly in the broader major depressive disorder (MDD) population. Objective: To assess short-term and long-term antidepressant effects of psilocybin therapy in patients with MDD. Design, Setting, and Participants: This double-blind,...

Background: Treatment-resistant depression (TRD) affects a significant proportion of individuals with major depressive disorder and remains difficult to manage with conventional treatments. Psychedelic-assisted therapies and neuromodulation have emerged as innovative interventions targeting neurobiological mechanisms beyond traditional antidepressant approaches. Objectives: This scoping review...

Abstract Background: Conventional pharmacotherapy for treatment-resistant depression (TRD) has been found to provide limited benefit in a subset of patients. Psilocybin‑assisted therapy has emerged as a promising modality due to its rapid‑acting antidepressant effects and favourable tolerability profile shown in early trials. Despite growing research interest in psilocybin‑assisted therapy the...

Aging is associated with chronic, low-grade inflammation ("inflammaging"), which contributes to neuropsychiatric and neurodegenerative disorders such as depression, Alzheimer's disease, and Parkinson's disease. Conventional pharmacotherapies often provide limited benefit in older adults and are further complicated by polypharmacy and drug-drug interactions. Psilocybin, a serotonergic...
