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...
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...
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...
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...
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)....

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....
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...
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...
