Importance: Few pharmacotherapies are approved for treatment-resistant depression, and many patients do not achieve remission following treatment with those therapies. Objective: To examine the efficacy and safety of single-day treatment with a synthetic formulation of inhaled mebufotenin (GH001) vs placebo in patients with treatment-resistant depression. Design, Setting, and Participants: This...

Major depressive disorder is a highly prevalent psychiatric condition that can affect individuals across the lifespan, yet its pathophysiology remains incompletely understood. Classical hypotheses, informed by preclinical and clinical studies, emphasized dysregulated monoaminergic neurotransmission and guided the development of widely prescribed antidepressants, including selective serotonin...

Treatment-resistant depression affects up to one third of patients with major depressive disorder and is frequently accompanied by persistent cognitive impairments that significantly hinder functional recovery. Emerging evidence suggests that sub-anesthetic esketamine does not appear to be associated with cognitive deterioration and may be associated with procognitive effects; however, no...

The trajectory and predictors of response under routine clinical care of esketamine nasal spray (ESK NS) over treatment-resistant depression (TRD) require elucidation. This retrospective, longitudinal cohort study was conducted across three Spanish centers. Adults diagnosed with TRD who initiated ESK NS and completed at least the induction phase were included. Assessments occurred at baseline,...

Contemporary psychiatry primarily utilizes biomedical models that categorize mental disorders through observable symptoms, which risks overlooking how these experiences are actually lived by individuals. This article examines melancholic depression through the lens of phenomenological psychopathology, arguing that it represents a radical, structural transformation of the subject’s...

Major depressive disorder (MDD) is a highly prevalent psychiatric illness for which rapid-acting antidepressants such as ketamine provide only transient benefit. Because κ-opioid receptor (KOR) signaling contributes to stress-related dysphoria and impaired neuroplasticity, we examined whether KOR antagonism could prolong ketamine’s antidepressant-like effects in a mouse model of adolescent...

To investigate the regulatory role of glutamatergic neurons in the medial prefrontal cortex (mPFC) in the antidepressant effects of esketamine. A total of 150 male C57BL/6J mice were randomly divided into 15 groups (n=10). The mice subjected to the chronic restraint stress (CRS), and those exhibiting depressive-like behaviors following CRS received either esketamine or saline treatment, and...

Depression and psychological distress are highly prevalent among patients with cancer and are associated with impaired quality of life, reduced treatment adherence, and poorer clinical outcomes. Standard pharmacological and psychosocial interventions often demonstrate limited efficacy or delayed onset of action in oncological and palliative settings. Psilocybin-assisted therapy has recently...

Electroconvulsive therapy (ECT) is an established treatment of major depressive disorder (MDD), particularly in severe cases and in cases resistant to pharmacological interventions. Anesthesia plays an important role in optimizing patient tolerability during ECT but may attenuate the treatment effect, as anesthetic agents elevate the seizure threshold. This review aims to examine the impact of...

Importance: Psychedelic-assisted therapy (PAT) trials have high levels of functional unblinding, which biases results when comparing PAT with blinded interventions. Because PAT is effectively always open label, treatment results should be compared with those of open-label traditional antidepressants (TADs), so potential benefits associated with patients knowing their treatment is equal between...
