Psychedelic Therapies in the Management of Post-Traumatic Stress Disorder

Journal of Education, Health and Sport July 16, 2026 Jakub Bajer, Aleksandra Włodarczyk, Hubert Kulawinek et al.

Background. Post-Traumatic Stress Disorder (PTSD) is an important public health challenge typically treated with trauma-focused psychotherapy and Selective Serotonin Reuptake Inhibitors (SSRIs). However, high rates of residual symptoms associated with these standard treatments have led to a renewed interest in psychedelic-assisted therapies. Aim. This review attempts to examine emerging...

Interrogating roles for VTA dopamine neurons in locomotion and ultrasonic vocalizations elicited by different classes of rewarding drugs.

Psychopharmacology July 14, 2026 Kate A Lawson, Stephen V Mahler

In humans, researchers can readily query the subjective states elicited by drugs of abuse, but no such introspective readout is currently available in rodents. Rats can convey information relevant to their internal states via ultrasonic vocalizations (USVs). We sought to measure USVs and locomotor behavior as parallel behavioral indices of the effects of drugs and ventral tegmental area...

Enhancing plasticity to treat depression and other central nervous system diseases using event-driven pharmacology.

Journal of Psychopharmacology July 13, 2026 Todd D Gould, Sanjay J. Mathew, Maurizio Fava et al.

The occupancy-driven pharmacology model in psychopharmacology has guided drug discovery and development for decades, whereby the goal is stable receptor occupancy over an extended period with a direct relationship of drug exposure to pharmacodynamic and therapeutic response. Event-driven pharmacology (EDP) is a concept where the acute pharmacodynamic actions of a plastogen, a transient binding...

A conceptual framework based on current and emerging treatments for treatment-resistant depression: mechanistic evolution, clinical evidence, and future directions.

Expert Review of Neurotherapeutics July 1, 2026 Stephen Rush, Henry A Nasrallah

Treatment-resistant depression (TRD) represents an unmet challenge, accounting for disproportionate morbidity, disability, and healthcare burden in depression. Limitations of monoaminergic antidepressants have prompted a conceptual shift toward models emphasizing impaired neuroplasticity, synaptic dysfunction, and network dysregulation. This expert review synthesizes preclinical, translational,...

Psychedelics as a potential treatment for borderline personality disorder: A narrative review.

Psychiatry Research July 1, 2026 Erin Artna, Guneet Sandhu, Noah Chisamore et al. 1 citation

Borderline personality disorder (BPD) is a serious mental illness with high rates of morbidity and stigma; however, successful remission is frequently limited by a paucity of accessible treatment options. In an era of growing interest in psychedelics as novel psychiatric treatment modalities, patients with BPD are often excluded from research due to perceived safety risks, particularly...

Psychedelics in treatment-resistant depression: a comprehensive review of mechanisms, clinical evidence, and recommendations.

Neuropsychiatrie June 30, 2026 Cielo A Estela-Fernandez, Reem Mohamed Yousif Elsheikh, Dal Bianco Beatrice et al.

Major depressive disorder (MDD) is a heterogeneous, debilitating disorder. A distinct subgroup within the MDD spectrum is identified to have treatment-resistant depression (TRD). There is an impetus to find alternative treatments for TRD to reduce disease burden and improve quality of life. Psychedelics have been used in the treatment of various psychiatric disorders since the 1950s, with...

Intrinsic excitation-inhibition imbalance in major depressive disorder.

Journal of Affective Disorders June 29, 2026 Yao Ge, Lijuan Chen, Yu Shen et al.

Major depressive disorder (MDD) ranks among the foremost contributors to disability worldwide, yet its neurophysiological mechanisms remain poorly understood. Excitation-inhibition (E/I) imbalance has been implicated in MDD pathophysiology, but cortex-wide E/I ratio and its molecular substrates in MDD remain unknown. Resting-state functional magnetic resonance imaging data from 254 MDD patients...

NMDA receptor subtype differential affinity as a key enabler for precision neuropsychiatry.

Progress in Neuro-Psychopharmacology and Biological Psychiatry June 20, 2026 Aline Freyssin, Reina Benabou, Hanna Zoe Müller et al.

Despite recent advances in neuropsychiatry, translational development for many targets remains challenging, particularly when receptors exist as families with complex subunit-dependent pharmacology and safety concerns. This is the case for NMDA receptor (NMDAR) antagonists. R,S-ketamine illustrates this issue: although it produces rapid antidepressant effects in the clinic, its use is limited...

Psychometric validation of the French version of the five-dimensional altered states of consciousness questionnaire (5D-ASC) and associated 11 OAV subscales.

Progress in Neuro-Psychopharmacology and Biological Psychiatry June 20, 2026 Ewen Kervadec, Pauline Mathieu, Baptiste Fauvel et al.

The renewal of psychedelic medicine has garnered significant scientific interest, with large efforts dedicated to the understanding of the complex subjective experiences induced by these substances. The Altered States of Consciousness (ASC) questionnaire represents the most comprehensive instrument for measuring such experiences yet lacks a validated French translation despite its centrality to...

Development and validation of a short-form (6-item) version of the clinician-administered dissociative states scale (CADSS-SF).

European Journal of Psychotraumatology June 15, 2026 V Ursule Taujanskaite, Sunjeev K. Kamboj

Background: State dissociation is commonly assessed using the Clinician Administered Dissociative States Scale (CADSS; 19-items). A briefer CADSS would have many advantages, enabling assessment of transient dissociative states and allowing repeated assessment within short intervals while minimizing participant burden. This is especially relevant in studies of dissociative drugs which cause...
