Ketamine and its enantiomer esketamine are efficacious in 30-35% of the patients with treatment-resistant depression (TRD). Increased serum brain-derived neurotrophic factor (BDNF) following treatment has been proposed as a potential biomarker of antidepressant response. This is based on studies evaluating single intravenous ketamine treatment. BDNF expression at different treatment schedules...
OBJECTIVE: To establish consensus recommendations for initiating dextromethorphan-bupropion extended release (45 mg/105 mg) (AUVELITY) for the treatment of major depressive disorder (MDD) in adults. METHODS: = 10) with clinical experience treating MDD participated in a 3-stage modified Delphi panel procedure. An initial literature review was performed to assist in the development of draft...
Abstract This randomized controlled trial examined whether mindfulness-based exposure and response prevention (MB-EX/RP) improves outcomes for adults with comorbid obsessive-compulsive disorder (OCD) and major depressive disorder (M, addressing cognitive rigidity and emotion dysregulation that can limit standard exposure and response prevention. Fifty-four participants were assigned to MB-EX/RP...
The question of whether the striking antidepressant effects of psilocybin reported in randomised trials can be reproduced in everyday care remains largely unanswered. This is because those trials enrol highly selected patients, withdraw concomitant medication and deliver treatment under tightly standardised protocols. In this issue, Jungwirth et al. provide one of the first responses from...
The introduction of ketamine and its S-enantiomer, esketamine, has been one of the most consequential advances in treatment-resistant depression (TRD) in recent decades, demonstrating that rapid and clinically meaningful antidepressant effects can occur within hours, even in patients who have not responded to conventional treatments.However, this advance has not resolved the clinical problem of...
Background: Cannabis use among adolescents with depression is prevalent. Dysfunction of the reward system has been implicated in each condition separately, yet rarely examined together. Here, we investigated resting-state properties of reward networks in an adolescent sample with diverse internalizing psychopathology and cannabis use patterns. Methods: Clinicians interviewed adolescents and...
Mindfulness-based cognitive therapy (MBCT) was developed for relapse prevention in people with remitted depression but is increasingly used for those with difficult-to-treat depression (DTD). A key question regarding this broader application is whether ongoing depressive symptoms constrain therapeutic responsiveness or disrupt MBCT's proposed mechanism, decentering. We explored whether baseline...
Bipolar II disorder (BD-II) is characterised by hypomanic and depressive episodes with the latter tending to dominate the clinical course of the disorder, and they are often associated with suicidality. Despite available guideline-based recommendations for first-line pharmacological treatments, patient outcomes remain suboptimal, especially for those with chronic depression and suicidal...
The occupancy-driven pharmacology model in psychopharmacology has guided drug discovery and development for decades, whereby the goal is stable receptor occupancy over an extended period with a direct relationship of drug exposure to pharmacodynamic and therapeutic response. Event-driven pharmacology (EDP) is a concept where the acute pharmacodynamic actions of a plastogen, a transient binding...
Abstract Background Research on psilocybin's antidepressant effects has been investigated rigorously over the last 20 years. Psilocybin has been used in both major depressive disorder (MDD) and treatment resistant depression (TRD) cohort with promising results. Aims The aim of this review was to summarize the reporting practices used in psilocybin-assisted therapy (PAT) trials for MDD and TRD....
