Quality of Life in Patients with Treatment-Resistant Depression Treated with Intranasal Esketamine as Add-On Therapy to an SSRI—A Prospective, Comparative Study in Real-World Clinical Practice

Pharmaceuticals October 19, 2026 Daniel Szawarnoga, Joanna Fojcik, Michał Kamil Górski et al.

Treatment-resistant depression (TRD) remains one of the most clinically challenging forms of depressive disorders. In many patients, reduction in symptom severity does not translate into full functional recovery; therefore, assessment of treatment effectiveness should also include health-related quality of life (HRQoL). Objective: The aim of the study was to compare changes in HRQoL in patients...

Baseline Response Criterion and Changes in Emotional Bias as Markers of Esketamine Response in Treatment-Resistant Depression

medRxiv October 15, 2026 Chlöé Müh, Pauline Favre, Isabel Karen Lütkenherm et al. preprint

Abstract Negative emotional bias, including reduced processing of positive information and negative interpretation of ambiguous stimuli, is a core feature of depression. Esketamine, an N-methyl-D-aspartate (NMDA) receptor antagonist with rapid antidepressant effects in treatment-resistant depression (TRD), reduces depressive symptoms, but its effects on distinct components of emotional...

Longitudinal peripheral DNA methylation remodeling following ketamine-assisted psychotherapy in major depressive disorder

Epigenetics October 15, 2026 Arghavan Nepton, Sonya C. Faber, Zachary A. Kaminsky et al.

Ketamine produces rapid antidepressant effects, but the molecular processes associated with their persistence remain poorly defined in humans. We examined longitudinal DNA methylation changes in 10 adults with major depressive disorder undergoing ketamine-assisted psychotherapy using two pre-treatment assessments (T1, T2) and one post-treatment assessment (T3). Participants received three...

Reality stabilization: a unified framework for psychosis and post-psychotic depression

Frontiers in Psychology October 14, 2026 Georgi Panov, Presiyana Panova

Both quantum mechanics and cognitive neuroscience challenge the classical view of a passively perceived reality. Instead, they suggest that reality arises through a process of selection and stabilization from a field of possibilities. This article proposes that this “reality stabilization” framework can unify our understanding of psychosis and post-psychotic depression—two conditions that are...

Intranasal Esketamine for Treatment-Resistant Depression: A Practical Clinical Guide to Patient Selection, Dosing, Combination Strategies and Adverse-Event Management

Preprints.org October 14, 2026 Domenico de Berardis, Tommaso Barlattani, Alessandro Carano et al. preprint

Intranasal esketamine has been available for treatment-resistant depression (TRD) since 2019, but the trials that led to its approval answer only some of the questions prescribers face. About 97% of trial participants had failed only one or two antidepressant classes, and patients with bipolar disorder, psychosis, obsessive–compulsive disorder, four personality disorders, moderate-to-severe...

The Hidden Therapeutic Bridge: Exploring Psilocybin’s Role in Depression, Inflammation, and Pain – A Narrative Review

Current Neuropharmacology October 14, 2026 Mareli Vázquez-Barreto, Mariana Ugarte-Rocha, Abraham Flores Vargas et al.

Mental disorders are among the leading causes of non-fatal health loss worldwide and are associated with significant individual, social, and economic burdens. On the other hand, neuropathic pain affects approximately 7-8% of the world's adult population and is a leading reason for medical consultations. A bidirectional relationship between depression and pain has been widely documented....

Ketamine administered biomedically or as psychedelic-assisted therapy in treatment-resistant depression: Differing efficacy based on depressive subtype or presence of childhood trauma?

Australasian Psychiatry October 13, 2026 Adam Bayes, Colleen Loo

ObjectiveThe ideas presented in this paper are based on a presentation at a festschrift event marking the retirement of Professor Gordon Parker from UNSW, Sydney. Drawing on Gordon's depressive subtyping approach and his critiques of a unitary view of major depressive disorder and treatment-resistant depression (TRD), we aim to (i) explore differing models of ketamine for TRD - biomedical...

Augmentation strategies for intravenous ketamine in treatment-resistant depression: A systematic review and meta-analysis.

Journal of Affective Disorders October 12, 2026 Reinhard Janssen-Aguilar, Jithin Joseph, Huda Al-Shamali et al.

Treatment-resistant depression (TRD) affects 30-60% of individuals with major depressive disorder and carries substantial morbidity and healthcare costs. Intravenous (IV) ketamine (KET) is a rapid-acting antidepressant, but benefits are often transient, prompting augmentation to sustain efficacy or improve tolerability. We conducted a systematic review and meta-analysis of randomized controlled...

Ketamine's mechanisms of action in major depressive disorder and treatment-resistant depression: Is brain topological change a candidate convergent systems-level pathway?

Asian Journal of Psychiatry October 12, 2026 Gia Han Le, Sabrina Wong, Simryn Selby et al.

Ketamine is a rapid-acting antidepressant with demonstrated efficacy in major depressive disorder and treatment-resistant depression, yet the mechanisms by which its molecular actions translate into sustained clinical improvement remain incompletely understood. Prevailing models have emphasized N-methyl-D-aspartate receptor antagonism and downstream glutamatergic signaling; however, convergent...
