Major depressive disorder (MDD) imposes a substantial burden worldwide, with treatment-resistant depression (TRD) and major depressive disorder with acute suicidal ideation or behavior (MDSI) representing two of the most severe clinical challenges. Conventional antidepressants often require several weeks to exert benefit, leaving patients symptomatic and at risk during this delay. Esketamine...

Treatment-resistant depression (TRD), defined as failure to respond to at least two adequately administered antidepressant (AD) regimens, imposes major clinical and economic burdens. Esketamine nasal spray offers rapid antidepressant clinical effects, yet previous evaluations compared it only with unrealistic comparators such as AD monotherapy. This study assessed the cost-effectiveness of...

Neuroimaging techniques offer valuable insights for understanding pharmacological treatment effects in neuropsychiatric disorders. Here, we present a novel approach that simultaneously assesses hemodynamic and neurometabolic brain responses to psychotropic drugs using interleaved pharmacological magnetic resonance imaging (phMRI) and pharmacological magnetic resonance spectroscopy (phMRS). This...

Background: Posttraumatic stress disorder (PTSD) is a severe and frequent affection that is highly comorbid to major depressive disorder. Comorbid PTSD and depression increase the risk of treatment-resistant depression (TRD), with a high risk of functional impairment and suicide. Esketamine nasal spray is a recent validated treatment for TRD, but its efficacy on comorbid TRD-PTSD remains...

Introduction: Treatment-resistant depression (TRD) represents a significant clinical challenge, particularly when associated with suicidal ideation. Intranasal esketamine has emerged as an effective therapeutic option in refractory cases, while monoamine oxidase inhibitors (MAOIs) remain relevant in the management of severe and resistant conditions. Objective: To describe the clinical course of...

Esketamine is a fast-acting antidepressant drug which induces acute psychoactive effects. The most frequent is a dissociative state which seems unrelated to therapeutic efficacy. Other esketamine-induced effects, including psychedelic-like mystical experiences, have been poorly studied in terms of phenomenology and frequency, and may carry specific therapeutic relevance. In this study, we...

Ketamine, a dissociative anesthetic, has been extensively used in clinical anesthesia and sedation. However, its use in general anesthesia is gradually declining because of numerous adverse effects. In 2019, esketamine was introduced to the Chinese market. This narrative review aimed to summarize the current status of clinical applications and research progress of esketamine and to explore its...

Background: Depression is a significant mental health condition affecting numerous individuals worldwide, leading to disability within society and posing a heightened risk of suicide, thereby diminishing overall quality of life. Depression, often a contributing factor in suicides, is associated with various prevalent medical conditions such as obesity, diabetes, stroke, Parkinson's disease, and...

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,...
