This research focuses on the promising use of esketamine in perinatal depression, a widespread disorder impacting postpartum women's mental health. Despite esketamine's known rapid antidepressant effects, its precise mechanisms are not fully understood. This study integrates clinical and preclinical approaches to explore esketamine's efficacy in treating perinatal depression and its actions...
INTRODUCTION Anhedonia, defined as the diminished ability to experience or anticipate pleasure, is a core symptom of major depressive disorder (MDD) and bipolar depression (BD), and associated with depression severity, suicidality and poor treatment outcomes. Conventional antidepressants demonstrate limited efficacy against anhedonia. Esketamine nasal spray (ESK-NS) - a novel NMDA receptor...
OBJECTIVE: This review explores ketamine's expanding role in managing both chronic pain and mental health conditions, focusing on its pharmacologic mechanisms, clinical applications, and therapeutic potential. We assess its analgesic properties, FDA-approved application in the form of Spravato (esketamine) for depression, and off-label use for analgesia and psychiatric disorders. METHODS: A...
Anxiety and depression are highly prevalent mental health disorders, imposing significant burdens on individuals and healthcare systems. Mindfulness-based cognitive therapy (MBCT) has demonstrated effectiveness in reducing these symptoms. Electronic health MBCT (eMBCT) offers a scalable alternative, but its efficacy in alleviating anxiety and depression in adults remains unclear. To examine the...
Abstract Background and Aims Psilocybin has emerged as a potential treatment for alcohol use disorder (AUD), but early efficacy data are inconsistent. Depression following alcohol detoxification significantly increases the risk of relapse. This pilot study aimed to evaluate the feasibility, acceptability, and preliminary efficacy of psilocybin‐assisted psychotherapy for patients with comorbid...
We investigated the potential role of the opioid system in modulating glutamatergic effects of ketamine administration in major depressive disorder. Twenty-six adults with major depressive disorder participated in a double-blind crossover study, receiving oral placebo or 50 mg naltrexone before an intravenous infusion of 0.5 mg per kg ketamine. Brain glutamatergic activity in the anterior...
Holistic management of persons living with Major Depressive Disorder (MDD) and Bipolar Disorder (BD) invites the need for evaluation of positive mental health (PMH; pleasure attainment and meaning-in-life), alongside conventional measures of psychopathology. The aforementioned dimensions of PMH involve aspects of mindfulness and grit. Herein, we evaluate these aspects using ecological momentary...
The current trial aimed to assess the effectiveness of Mindfulness-Based Stress Reduction training on salivary cortisol and α-amylase levels, anxiety and depression of students. This research was an experimental trial with a pre-test-post-test design and a control group. The statistical population of the research included all students studying in the universities of Khoy, Iran in 2021. The...
Comorbid mental health symptoms impact 30-40% of cancer patients, significantly compromising treatment adherence and increasing mortality rates. Among patients undergoing radiation therapy, which is delivered with palliative intent in nearly half of all cases and for those nearing end-of-life, these rates may be even higher. Emerging research underscores the promising potential of...
Objectives: (R)-ketamine hydrochloride injection is a novel, rapid-acting antidepressant for the treatment of treatment-resistant depression. The aim of this study was to assess the pharmacokinetics, safety, and tolerability of (R)-ketamine hydrochloride injection in healthy Chinese subjects following ascending single intravenous doses ranging from 10.0 mg to 180 mg. Methods: This randomized,...
Abstract Determining the scale of neural representations is a central challenge in neuroscience. While localized representations have traditionally dominated, evidence suggests information is also encoded in distributed, hierarchical networks. Recent research indicates that the hierarchy of causal influences shaping functional patterns serves as a signature of distinct brain states, with...
OBJECTIVES: Ketamine is a prototypical rapid-acting antidepressant for treatment-resistant bipolar depression (TRBD), yet many patients do not achieve a meaningful response. This study explored features of ketamine nonresponse in TRBD. METHODS: In a post hoc analysis of a naturalistic study, 35 TRBD patients received a four-week ketamine regimen (intravenous 0.5 mg/kg or oral 2.0/2.5 mg/kg)....
Depression during pregnancy is often overlooked and undertreated. Ketamine has been shown to exert prompt and sustained antidepressant effects in patients with depression, although concerns of potential neurotoxicity prohibit its use in pregnant women. Here, we aim to investigate the neurobehavioral effects of subanesthetic ketamine on pregnant mice and their offspring. We found that pregnant...

Interventional psychiatric procedures (IPPs) such as electroconvulsive therapy (ECT), transcranial magnetic stimulation (TMS), and ketamine intravenous treatments (KIT) are widely used for treatment resistant depression (TRD), but we lack studies of their real-world impact compared to standard outpatient medication management (MM). Longitudinal electronic health records of 22,481 patients in a...

Background: Insomnia, as one of the most common sleep disorders, is a significant health problem, especially among patients suffering from drug-resistant depression. Problems related to the quality of sleep in that population can significantly affect the effectiveness of treatment and quality of life, which is why it is necessary to search for effective therapeutic interventions in this area....
Ketamine has emerged as a versatile therapeutic agent with applications spanning anesthesia, pain management, and psychiatric disorders. This review examines ketamine's clinical utility across diverse administration routes, including intravenous, intramuscular, intranasal, and oral, emphasizing the need to individualize dosing regimens. We explore factors influencing ketamine dosing, such as...
Background: The present study investigated the sustained effects of a 5-week EmotionCore mindfulness training program on emotion regulation, emotional intelligence (EI), trait mindfulness, depression, and anxiety among 120 undergraduates, while exploring the mediating mechanisms of training effect and heterogeneous effects across subgroups. Methods: Participants were randomly assigned to a...
Depression in children is a concerning societal issue and can be associated with poor academic performance, school dropout, and poor overall quality of life. Additionally, child depression is often associated with parallel stress and depression in parents. This scenario highlights the urgent need for the development and implementation of accessible and scalable solutions that may cobenefit...
The therapeutic potential of psychedelic substances, particularly psilocybin, for treatment-resistant depression (TRD) has garnered considerable attention. However, the necessity of subjective psychedelic experiences for therapeutic efficacy remains unclear, creating a critical gap in the field. To determine whether subjective psychedelic experiences induced by psilocybin are required for its...
Cerebrolysin (CBL), a peptide derived from pig brain, is recognized for its neuroprotective and anti-inflammatory properties. This research aimed to investigate the effects of CBL on anxiety- and depression-like behaviors, spatial memory, the tryptophan/kynurenine (TRP/KYN) pathway, and inflammation in the prefrontal cortex (PFC) of a mouse model for schizophrenia. Thirty-six male BALB/c mice...
