Treating addiction with an addictive drug: the ketamine paradox revisited

Frontiers in Psychiatry July 9, 2026 Alqassem Y. Hakami

Background Substance use disorders (SUDs) and treatment-resistant depression (TRD) remain a major global health challenge, marked by high relapse rates and limited long-term effectiveness of existing treatments. Ketamine, a glutamatergic modulator with rapid neuroplastic effects, has emerged as a novel intervention for TRD and is increasingly investigated as an adjunctive treatment for...

A randomized controlled trial comparing a mindfulness-based program with standard therapeutic follow-up during pregnancy: Effects on maternal mental health, infant outcomes, and mother-infant attachment.

Contemporary Clinical Trials July 8, 2026 Clara Beauvois, Andrea Soubelet

Pregnancy and childbirth represent a major transition into motherhood, marked by psychosocial changes that may increase women's vulnerability to mental health difficulties such as prenatal depression, anxiety, or PTSD, in addition to physical pain. These difficulties can negatively impact maternal well-being, the mother-infant relationship, and child development. Prenatal mindfulness-based...

What therapy is effective for treating vivid dreams associated with antidepressant use?

Zenodo (CERN European Organization for Nuclear Research) July 4, 2026 preprint

There is no direct evidence for therapies specifically targeting vivid dreams from antidepressant use. Cognitive Behavioral Therapy, Imagery Rehearsal Therapy, and certain medications are viable options derived from broader contexts of nightmare treatment.

Effects of sub-anesthetic doses of esketamine on immune function and postoperative negative emotions in acoustic neuroma patients: a randomized clinical trial.

Annals of medicine July 3, 2026 Zheping Chen, Yaozhu Wang, Peilin Cong et al.

Patients undergoing acoustic neuroma (AN) surgery often experience postoperative negative emotions, including anxiety, depression, and immune function suppression. This trial evaluated whether perioperative sub-anesthetic esketamine improves early postoperative negative emotions and immune function. In this single-center, double-blind, randomized trial, 84 patients scheduled for AN surgery were...

Real‐World Effectiveness and Cost‐Differential of Intranasal Esketamine Versus Intramuscular Ketamine

Psychiatric Research and Clinical Practice July 2, 2026 Kush V. Bhatt, Tara Austin, Danny Alam et al.

Objective This study evaluated whether intramuscular (IM) ketamine is non‐inferior to intranasal (IN) esketamine for treatment‐resistant depression (TRD) and assessed differences in safety and healthcare costs. Methods In a retrospective, observational sequential cohort at the VA San Diego, 179 Veterans with TRD received eight treatments of either IN esketamine ( n = 89) or IM ketamine ( n =...

Microglial brain-derived neurotrophic factor (BDNF) supports the behavioral and synaptogenic effects of ketamine.

Brain, Behavior, and Immunity July 2, 2026 Samuel C Woodburn, Alexander M Kuhn, Kelly E Bosis et al.

Ketamine promotes spine growth on the apical dendrites of pyramidal neurons in the prefrontal cortex (PFC), which are critical for its behavioral effects. Follow-up studies show that brain-derived neurotrophic factor (BDNF) signaling is critical for these effects. In this context, we sought to determine if microglial BDNF contributes to the synaptic and behavioral effects of ketamine....

Effect of Yoga Intervention for Health Care Workers During the COVID-19 Pandemic: A Systematic Review.

Journal of Integrative and Complementary Medicine July 2026 I-Jung Chen, Yuan-Sheng Tzeng, Shu-Yu Wu et al.

Health care workers (HCWs) faced unprecedented stress, anxiety, and burnout during the COVID-19 pandemic. Yoga, a mind-body practice combining physical postures, breathing, and meditation, has demonstrated benefits for mental and physical resilience. This systematic review evaluated the effectiveness of yoga interventions in addressing mental health challenges and promoting overall well-being...

Dissociation and Antidepressant Response to Subcutaneous Esketamine: A Clinical Study

Journal of Psychiatric Research July 1, 2026 K S de Freitas Goncalves, Vagner Deuel O de Tavares, Fernanda Palhano-Fontes et al.

ABSTRACT: Introduction Ketamine and esketamine have reemerged as promising interventions for treatment-resistant depression (TRD), yet debate persists regarding the clinical relevance of acute dissociative experiences. This secondary exploratory analysis examined the relationship between dissociative experiences induced by subcutaneous esketamine and antidepressant response in patients with...

Combined Ketamine and Cognitive-Behavioral Therapy: Leveraging Metaplasticity to Enhance Treatment Outcomes

FOCUS: The Journal of Lifelong Learning in Psychiatry July 1, 2026 Morgan S. Hardy, S. William Li, Samuel T. Wilkinson

Over the past two decades, ketamine has emerged as a rapid-acting antidepressant, especially among patients with treatment-resistant depression. As an N-methyl-d-aspartate glutamate receptor antagonist, ketamine has reshaped the understanding of the underlying neurobiological mechanisms of depression treatment. Ketamine induces a transient state of enhanced neuroplasticity and likely...

N,N-dimethyltryptamine elicits antidepressant and anxiolytic effects in helpless mice: a comparative study with S-ketamine.

Neuropharmacology July 1, 2026 Anne Nathalia De Sousa-Silva, Clarissa de Almeida Moura, Carina Ioná De Oliveira Torres et al. 1 citation

N,N-dimethyltryptamine (DMT) is an naturally occurring indoleamine with hallucinogenic and antidepressant effects in humans. Here, we compared the effects of DMT and S-ketamine, a fast-acting antidepressant, in helpless mice. To induce helplessness, male single and group-housed mice were exposed to inescapable footshock stress; only helpless animals were subsequently treated with S-ketamine 10...
