Abstract A central challenge in neuroscience is understanding how the human brain is organised to support optimal functioning and adaptability. One approach to characterise complex brain dynamics is by artificially perturbing whole-brain models. Here, we asked whether whole-brain organisation under perturbation in major depressive disorder (MDD) changes after intervention with psilocybin and...

Introduction: Treatment-resistant depression (TRD) is a major public health and societal challenge, associated with persistent symptoms, functional impairment, and increased healthcare and economic burden. Intranasal esketamine has emerged as a rapid-acting adjunctive therapy with a distinct glutamatergic mechanism of action. This systematic review summarizes current evidence on its...

Background: Intranasal esketamine (ESK-NS) is an effective treatment for treatment-resistant depression (TRD), but whether antidepressant outcomes differ by sex and age remains insufficiently explored. Methods: This secondary analysis of the REAL-ESK study included 210 patients with TRD treated with ESK-NS in routine clinical practice and assessed at baseline (T0), one month (T1), and three...

Depression and its severe outcomes, suicidal ideation and behavior, are exacerbated by stress. A broad literature links dysregulation of the hypothalamic-pituitary-adrenocortical (HPA) stress response system to depression, suicidal ideation and behavior. Our midazolam-controlled clinical trial of subanesthetic, intravenous ketamine infusion for suicidal depressed patients found rapid reduction...

Major depressive disorder (MDD) and treatment-resistant depression (TRD) are prevalent and debilitating conditions. Over 50% of patients have inadequate response to first-line serotonergic antidepressants and are left with suboptimal treatment options. Rapid-acting and individually tailored treatments for MDD remain major unmet needs. This review discusses promising rapid-acting treatments,...

Introduction: Depressive disorders are one of the greatest public health challenges worldwide, affecting up to 16% of the population over a lifetime and significantly impacting quality of life, disability, and premature mortality. Major depressive disorder (MDD) is a leading cause of disability, despite the availability of numerous treatment options. In 20–50% of patients, traditional...

Background: Treatment-resistant depression (TRD) is associated with substantial functional impairment, suicide risk, and health-care costs. Ketamine and its S-enantiomer, esketamine, have emerged as rapid-acting glutamatergic treatment options for TRD. Aim: This review aims to synthesize current evidence on the different ketamine administration routes for TRD, with a focus on acute and...

Abstract Major depressive disorder (MDD) is a leading cause of disability worldwide with risk of onset and recurrence linked to depressive ruminative thought patterns. Mindfulness-based cognitive therapy (MBCT) is an evidence-based treatment for depression that targets the ability to recognise, decenter, and disengage from ruminative thought patterns. Elucidating how MBCT impacts hierarchical...

Background: Guided by Acceptance and Commitment Therapy (ACT), this study examined whether trait mindfulness and psychological inflexibility and experiential avoidance-related processes, assessed using the Acceptance and Action Questionnaire-II (AAQ-II), were statistically linked to the association between physical exercise and depressive symptoms among college students. Methods: A...
