Psilocybin has shown long-lasting antidepressant effects in preclinical and clinical trials, but the mechanisms responsible are unclear. As both passive coping strategies and pattern separation deficits are characteristics of major depression, we used adult female rats subjected to adolescent chronic restraint stress (aCRS) to investigate the effects of psilocybin on forced swim test (FST) and...

Background: Patients with missed miscarriages are usually accompanied by varying degrees of depression, which is closely related to the patient's prognosis. We investigated whether Esketamine could alleviate postoperative depression symptoms in patients with missed miscarriages who underwent painless curettage.

Ketamine therapies can offer rapid relief of depression and an antisuicidal effect, making them of particular interest for adolescents with treatment-resistant depression. In 1 randomized, double-blind study of adolescents with severe major depression, ketamine had a strong effect size for reducing depressive symptoms 24 hours after infusion. Currently, there is minimal investigation and few...

Abstract Background Preclinical evidence indicates that the κ-opioid receptor (KOR)/dynorphin pathway is implicated in depressive-like behaviors. Ketamine is believed to partly exert its antidepressant effects by modulating the opioid system. This post hoc study examined the following research questions: (1) at baseline, were there differences in KOR or dynorphin plasma levels between...

Introduction Synapses and spines play a significant role in major depressive disorder (MDD) pathophysiology, recently highlighted by the rapid antidepressant effect of ketamine and psilocybin. According to the Bayesian brain and interoception perspectives, MDD is formalized as being stuck in affective states constantly predicting negative energy balance. To understand how spines and synapses...

Objective Self-compassion as an outcome and potential mediator in mindfulness-based interventions has gained increased attention in the last years. However, most mediation studies had several methodological shortcomings which precluded robust conclusions regarding its mediating role. This randomized controlled study aimed to address these issues by assessing self-compassion, as proposed...

Abstract Objectives Indigenous university students experience high rates of anxiety and depression due primarily to the pernicious and persistent effects of colonialism, racism, and discrimination. Mindfulness-based interventions (MBIs) hold promise, but likely require adaptation to make them culturally relevant for Indigenous peoples. We sought to gather Indigenous students’ perspectives on...

BackgroundThe emergence of the COVID-19 pandemic has created an environment in which numerous determinants of poor mental health are intensified. Lockdown, re-lockdown, and media coverage of the spread of the virus, have the potential to contribute to increased levels of anxiety and depression. Mindfulness may act as a buffer against COVID-19-related depressive and anxiety disorders.MethodsWe...

Introduction: Compelling evidence indicates that a single sub-anesthetic dose of (S)-ketamine elicits rapid and robust antidepressant effects. However, the underlying mechanisms behind the antidepressant effects of (S)-ketamine remain unclear. Methods: Here, using a chronic variable stress (CVS) model in mice, we analyzed changes inthe lipid compositions of the hippocampus and prefrontal cortex...

Cognitive impairment has been observed in patients with various psychiatric disorders, including schizophrenia, major depressive disorder (MDD), and bipolar disorder (BD). Although modern therapeutic drugs can improve certain symptoms (i.e., psychosis, depression) in these patients, these drugs have not been found to improve cognitive impairment. The N-methyl-D-aspartate receptor antagonist...

Introduction Current treatment options for major depressive disorder (MDD) have limited efficacy and are associated with adverse effects. Recent studies investigating the antidepressant effect of serotonergic psychedelics—also known as classic psychedelics—have promising preliminary results with large effect sizes. In this context, we conducted a review of the putative neurobiological...

Objectives: At least one in four persons with bipolar disorder (BD) are estimated to have experienced auditory verbal hallucinations (AVH) or heard voices at some point. Yet few studies have investigated AVH in detail in this population. This preliminary study examined the phenomenology of AVH in BD to identify commonalities and differences relative to other psychiatric disorders where AVH are...

In the present study, we examined the effectiveness of three interventions on emotion dysregulation and insomnia severity: 1) mindfulness; 2) physical activity, and 3) mindfulness plus physical activity. Method A total of 50 participants (mean age...

Three weeks after dosing, psilocybin 25 mg and, to a lesser degree, 10 mg improved measures of patient-reported depression severity, anxiety, affect, and functioning. These results extend the primary findings from the largest randomised clinical trial of psilocybin for TRD to examine other outcomes that are of importance to patients.

Background Dysfunction of the amygdala is the core pathogenesis of major depressive disorder (MDD). However, it remains unclear whether ketamine treatment could modulate characteristics of amygdala-related networks. We aimed to explore the relationship between changes in the resting-state functional connectivity (RSFC) of the amygdala and the treatment of ketamine in MDD patients and to...

Results of a systematic review and meta‐analysis comprising six clinical trials suggest that electroconvulsive therapy (ECT) is more efficacious than ketamine in reducing the severity of depressive symptoms in patients with a major depressive episode. No significant between‐group differences in the prevalence of adverse events were observed. Results of the meta‐analysis were published online...
