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...

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,...

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...

BACKGROUND: Intranasal esketamine has recently emerged as an innovative treatment option for treatment-resistant depression (TRD). This retrospective, uncontrolled study aimed to evaluate the real-world effectiveness of esketamine in an naturalistic inpatient setting and explore demographic and clinical factors associated with treatment response. METHODS: We conducted a chart review of 101...

Treatment-resistant depression (TRD) remains a major clinical challenge, with inflammation increasingly implicated in its pathophysiology. C-reactive protein (CRP), an accessible biomarker, has emerged as a potential predictor of antidepressant response. While intravenous and intranasal ketamine have shown anti-inflammatory effects, evidence linking inflammation and clinical outcomes remains...

Treatment-resistant depression (TRD) presents a complex clinical challenge, particularly when comorbid with substance use disorders (SUDs) or other compulsive behaviors. With up to a third of major depressive disorder (MDD) patients failing to respond to standard antidepressant therapies, there is growing interest in interventions such as esketamine, a glutamatergic N-methyl-D-aspartate (NMDA)...

Major depressive disorder (MDD) is a leading cause of disability worldwide and contributes significantly to the global burden of disease. Recent data show an increasing prevalence of treatment-resistant depression (TRD). Patients with autism spectrum disorder (ASD) often exhibit MDD as a comorbidity and it is often resistant to conventional treatments. ASD determines emotional dysregulation and...

Background: Treatment-Resistant Depression (TRD) often persists despite adequate pharmacotherapy. Intranasal Esketamine and accelerated repetitive Transcranial Magnetic Stimulation (aTMS) are rapid-acting options, but head-to-head comparisons remain limited. Methods: We conducted a retrospective study on TRD patients receiving either aTMS (n = 18) or Intranasal Esketamine (n = 22). Depression...
