Esketamine Use in Treatment-Resistant Depression with Comorbid ADHD and Autistic Traits: A Case Report

European Psychiatry June 1, 2026 E. D. Cindik-Herbrueggen, A. S. Kucukali

Introduction Adult attention-deficit/hyperactivity disorder (ADHD) frequently co-occurs with mood and anxiety disorders (Sandstrom et al. Acta Psychiatr Scand 2021;143 380–391), and when major depressive disorder (MDD) is present, it often follows a treatment-resistant course (Thapar et al. J Child Psychol Psychiatry 2023;64 4–15). Intranasal esketamine, a non-competitive NMDA-receptor...

Introduction Ketamine and esketamine exert rapid antidepressant and dissociative effects, and the growing clinical use of intranasal esketamine for depression opens the possibility of large-scale electroencephalography (EEG) studies to explore their mechanisms through a non-invasive approach. However, understanding the neurophysiological basis of these effects requires a clear synthesis of...

Modes of Attention and the Clinical Mind: Distinguishing Meditation, Mindfulness, and Contemplation in Psychiatry

European Psychiatry June 1, 2026 J. B. French, J. Kar, B. R. Carr

Introduction The psychiatric incorporation of mindfulness has advanced without a parallel precision in definition. Within both clinical and lay discourse, mindfulness is often conflated with meditation broadly, or with forms of contemplation oriented toward ethical or spiritual ends. This conceptual slippage obscures distinct phenomenological structures and risks importing unexamined...

Mindfulness Facets, Nature Relatedness, and Eco-Anxiety: Evidence from a Hungarian Adult Sample

European Psychiatry June 1, 2026 R. Szegedi, F. Mónus, Á. Bernáth et al.

Introduction Eco-anxiety—though not a formal diagnosis—captures climate-related distress overlapping with anxiety-spectrum processes. While mindfulness is often framed as protective, facet-level links to eco-anxiety are underexplored in Central/Eastern Europe. Ecological connectedness may also heighten sensitivity to environmental threat. We examined how mindfulness facets and nature...

The therapeutic potential of psychedelic drugs: past, present, and future

European Psychiatry June 1, 2026 D. Nutt

Abstract The last decade has seen a remarkable resurgence of interest in psychedelic drugs such as psilocybin (from magic mushrooms) LSD and DMT (dimethyl tryptamine – the active ingredient of ayahuasca). This has been driven by the discovery that these psychedelics all act agonists of 5-HT2A receptors plus human imaging studies that reveal this action leads to profound alterations in brain...

The need to find more evidence-based pharmacological approaches to both TRD and BD is acute due to the high rates of partial response or...

Care Next Door: Community Outpatient Esketamine Across Urban and Rural Clinics

European Psychiatry June 1, 2026 J. García Jiménez, S. Posik, B. Herrejón et al.

Introduction Treatment-resistant depression (TRD) is highly burdensome. Intranasal esketamine is effective, yet hospital-centric delivery adds travel and continuity barriers that may hinder adherence and outcomes. We hypothesize that community outpatient, patient-proximal delivery —often with the patient’s usual psychiatrist—improves effectiveness, engagement and acceptability, consistent with...

Is the antidepressant efficacy of ketamine and esketamine mediated via opioid mechanisms?

European Psychiatry 2026 Andy Lu, Heidi Xu, Gia Han Le et al. 4 citations

The reported mixed findings suggest that the opioid system may exert a partial mediating effect of ketamine in TRD. However, given the inconsistent attenuation of ketamine's antidepressant effects by opioid receptor antagonists, the opioid system likely functions as a context-dependent modulator rather than a primary mediator, particularly at standard antidepressant doses.
