Electroconvulsive Therapy and (Es)Ketamine in Treatment-Resistant Depression: A Review of Current Evidence

European Psychiatry June 1, 2026 J. Marta, Â. Ferreira, C. Batista et al.

Introduction Treatment-Resistant Depression (TRD) is a major clinical challenge, affecting about 30% of patients with major depressive disorder. It is associated with high morbidity and mortality, reflected in increased suicide risk, hospitalizations, and impaired quality of life. Electroconvulsive Therapy (ECT) remains the therapeutic gold standard, particularly in severe cases with psychotic...

Longitudinal Assessment of Ketamine-Assisted Community of Practice Therapy: A Retrospective 5-Year Study on Depression, Anxiety and PTSD

European Psychiatry June 1, 2026 A. Kuzma-Hunt, Z. Hamadeh, V. Tsang

Introduction Ketamine-assisted therapy shows rapid benefit in treatment-resistant depression, anxiety, and PTSD (Walsh et al. BJPsych Open 2022;8:e19). The Roots to Thrive Ketamine assisted Therapy (RTT-KaT) program is a unique 12-week program that combines 12 Community of Practice (group therapy) sessions and three ketamine medicine sessions (Tsang et al. Ther Adv Psychopharmacol...

Trial of Subcutaneous Ketamine for Psychotic Depression in an Older Adult With Comorbid Physical Illness: A Case Report

BJPsych Open June 1, 2026 Roshan Ganeshan, Tharun Zacharia

Aims: Ketamine is an N-methyl-D-aspartate (NMDA) receptor antagonist used for anaesthesia and analgesia, with increasing interest in its rapid antidepressant effects. This case evaluates the feasibility, tolerability and clinical response to subcutaneous ketamine in a medically frail older adult with psychotic depression, hypothesising that ketamine would rapidly improve engagement and...

Long-term maintenance therapy with ketamine infusions for treatment-resistant depression: a retrospective chart review

European Psychiatry June 1, 2026 E. Peters, A. Al Hasani, K. Shukla et al.

Introduction Ketamine therapy for treatment-resistant depression has a well-established rapid antidepressant effect for acute symptom management. However, there is far less research on the efficacy of long-term maintenance therapy for relapse prevention. Objectives To examine the utility of long-term maintenance therapy with ketamine infusions delivered in a naturalistic treatment setting....

Does Intranasal Esketamine Show Differential Efficacy with SSRIs versus SNRIs in Treatment-Resistant Depression?

European Psychiatry June 1, 2026

Introduction Treatment-resistant depression (TRD) represents a major challenge in psychiatry. Nearly one-third of patients with major depressive disorder fail to achieve remission despite adequate antidepressant therapy, and about 30% attempt suicide during their lifetime. Given this elevated risk, identifying treatments that rapidly reduce depressive symptoms and suicidality while improving...

Clinical Outcomes of Ketamine Therapy for Depression, Anxiety, and PTSD in Post-TBI Patients

European Psychiatry June 1, 2026 W. Aldulaimy, A. Shah

Introduction TBI patients often suffer from severe, treatment-resistant depression and PTSD. Ketamine shows promise in non-TBI populations, but its efficacy in TBI patients needs exploration for efficacy and tolerability. Objectives Evaluate ketamine’s clinical effectiveness and safety (PHQ-9, GAD-7, PCL-5 scores) in post-TBI patients, comparing IM, intranasal, and oral routes. Methods Design:...

Addressing diversity gaps in esketamine clinical trials: a registry-based cross-sectional analysis of sex, race and ethnicity.

International journal of psychiatry in clinical practice June 1, 2026 Damian Swieczkowski, Aleksander Kwaśny, Michal Pruc et al.

To explore sex, racial and ethnic disparities in esketamine clinical trials for mental health disorders registered on ClinicalTrials.gov. We conducted a registry-based cross-sectional analysis of interventional esketamine trials with results posted on ClinicalTrials.gov (cut-off date: 10 February 2025). Using predefined eligibility criteria, two investigators independently extracted and...

Long-term treatment with esketamine nasal spray in patients with treatment resistant depression: Results from the ESCAPE-LTE study.

European neuropsychopharmacology : the journal of the European College of Neuropsychopharmacology June 1, 2026 Andreas Reif, Yağcıoğlu Ae Anıl, Istvan Bitter et al. 3 citations

Optimising patient outcomes in treatment resistant depression (TRD) requires treatments which provide sustained remission, without relapse, and tolerability in the long term. ESCAPE-LTE (NCT04829318) was a phase IV, single-arm, 2-year (104 weeks) long-term extension of ESCAPE-TRD (NCT04338321; 32 weeks), a rater-blinded, randomised, active-controlled trial, which evaluated the safety,...

Effectiveness and factors associated with esketamine response during the 4-week induction period for treatment-resistant depression: post-hoc analysis of the real-world ESKALE study.

Journal of Psychiatric Research June 1, 2026 Ludovic Samalin, Maud Rothärmel, Lila Mekaoui et al.

In patients with treatment-resistant depression (TRD), the efficacy and tolerance of intranasal esketamine (ESK) spray, alone or combined with oral antidepressants, has been supported by clinical trials and observational studies. The French real-world ESKALE study assessed the benefit of ESK in 157 patients with TRD. In this post-hoc analysis of the ESKALE study we aimed to describe the...

Regional Blood Flow Signatures of Opioidergic Modulation of Ketamine in Major Depressive Disorder: A Randomized Crossover Study.

The American journal of psychiatry June 1, 2026 Luke A. Jelen, Owen O'Daly, Fernando O Zelaya et al. 2 citations

Accumulating evidence suggests that the opioid system may modulate ketamine's rapid antidepressant effects. The objective of this study was to test whether opioid system modulation via naltrexone alters ketamine's acute effects on regional cerebral blood flow (rCBF) in major depressive disorder (MDD), and whether these changes relate to symptom measures and map onto receptor density profiles....
