Background Late-life depression with inadequate antidepressant response is a pressing clinical issue with limited proven therapies. Nitrous oxide (N 2 O) may offer a new therapeutic avenue with rapid and safe antidepressant effects in late-life depression with inadequate antidepressant response. Methods We conducted a double-blind, randomised, placebo-controlled, single-dose trial (November...

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...

Abstract Mindfulness training (MT) and progressive muscle relaxation (PMR) are widely used stress-reduction practices, yet their neurochemical specificity remains almost unexplored. In a randomized, pre–post study, 30 healthy right-handed female speech-language therapy students were assigned to six weeks of MT or PMR. Short-echo time single-voxel H 1 -MRS (3T PRESS, TE ≈ 35 ms) and structural...

Current antidepressants have shown certain limitations in the treatment of unipolar depression. Their long onset of action, interactions, and side effects are obstacles to achieving lasting remission of this prevalent, often chronic or recurrent, pathology. Faced with this clinical necessity, research efforts have intensified in recent years around psychedelic drugs, with a particular focus on...

ABSTRACT Dissociation is a widespread difficulty among patients suffering from Posttraumatic Stress Disorder (PTSD). However, there is no gold standard treatment for dissociative symptoms. Recent studies propose a cognitive and behavioral conceptualization for dissociation. The aim of this study was to explore the efficacy of a group program of Dissociation-Focused Cognitive Behavior Therapy...

Mindfulness meditation (MM) and hypnosis practices are gaining interest in mental health, but their physiological mechanisms remain poorly understood. This study aimed to synthesize the functional, morphometric and metabolic changes associated with each practice using magnetic resonance imaging (MRI), and to identify their similarities and differences. MRI studies investigating MM and hypnosis...

We conducted a scientometric analysis to outline clinical research on posttraumatic stress disorder (PTSD). Our primary objective was to perform a broad-ranging scientometric analysis to evaluate key themes and trends over the past decades. Our secondary objective was to measure research network performance. We conducted a systematic search in the Web of Science Core Collection up to 15 August...

Nitrous oxide (N2O) has recently emerged as a potential fast-acting antidepressant but the cerebral mechanisms involved in this effect remain speculative. We hypothesized that the antidepressant response to an Equimolar Mixture of Oxygen and Nitrous Oxide (EMONO) would be associated with changes in cerebral connectivity and brain tissue pulsations (BTP). Thirty participants (20 with a major...

ABSTRACT Introduction A number of studies have investigated the relationship between mindfulness and dissociation and suggested that mindfulness-based interventions could be effective in the treatment of dissociative symptoms. A recent study in healthy volunteers found that attention and emotional acceptance mediates this relationship. However, no study has yet been performed among a clinical...

Introduction: Major depressive disorder (MDD) is more likely to resist to usual treatment when it is associated with post-traumatic stress disorder (PTSD). Capitalizing on the effect of ketamine in both treatment-resistant depression (TRD) and PTSD, we conducted a study in order to assess the efficacy of intranasal (IN) Esketamine in patients having TRD with comorbid PTSD. Materials and...

Henri Ey suggested that all hallucinations occur against the background of depersonalization, which is an alteration in experience that people find hard to describe, where the subject feels a strangeness pervading the world and her/his own body, emotions and thoughts. Embracing Ey’s proposal, this paper draws a comparison between depersonalization in hallucinations and depersonalization in some...
