Cognitive and psychotic effects of ketamine "short- vs. long-term" therapy in a rat model of depression: Hippocampal TrkB/Akt/GSK-3β/mTOR/autophagy trajectories.

Progress in Neuro-Psychopharmacology and Biological Psychiatry September 1, 2025 Safaa K. Aref, Mohamed Z. Habib, Dalia M. Eid et al. 7 citations

Accumulating evidence indicates the role of ketamine as a rapid-onset antidepressant, with a rising controversy regarding its cognitive and psychotic effects, especially with long-term use. However, no previous experimental study has directly compared short-term and long-term ketamine effects using a time schedule that simulates infusion protocols in major depressive disorder patients. This...

Intravenous Ketamine Followed by Intranasal Esketamine in 2 Subsequent Treatment-resistant Depressive Episodes: Insights From a Case Series.

Journal of Psychiatric Practice September 1, 2025 Matteo Carminati, Mattia Tondello, Barbara Barbini et al. 2 citations

Treatment-resistant depression (TRD) remains a relevant issue in psychiatric practice, driving the exploration of innovative therapeutic alternatives. Ketamine and its enantiomer, esketamine, are emerging as treatments known for their effectiveness as rapid-acting antidepressants. Although previous comparative studies have highlighted some differences in their effects, they did not concurrently...

Self-Reported Improvements in Comorbid Post-Traumatic Stress Disorder Symptoms, Depression, Anxiety, and Sleep Among Real-World Patients Receiving Medical Ketamine: Exploring the Role of Adjunct Therapies.

European Journal of Trauma & Dissociation September 1, 2025 Shahar Almog, Albert Garcia‐romeu, Kathryn Walker et al. 1 citation

Post-traumatic stress disorder (PTSD) presents severe symptomology and often co-occurs with depression, warranting novel treatment approaches to address both conditions simultaneously. Ketamine has emerged as a rapid antidepressant and potential treatment for PTSD, with some real-world evidence for effectiveness regardless of comorbidities. The purpose of this secondary analysis was to explore...

Comparative efficacy and safety of intravenous racemic ketamine, repetitive transcranial magnetic stimulation and electroconvulsive therapy for Stage 2 or higher treatment-resistant depression: A systematic review and network meta-analysis.

Psychiatry and Clinical Neurosciences Reports September 1, 2025 Itsuki Terao, Takahiro Tsuge, Tomoo Sato et al. 2 citations

Although electroconvulsive therapy (ECT) is the standard treatment for Stage 2 or higher treatment-resistant depression, it has several drawbacks. Repetitive transcranial magnetic stimulation (rTMS) and intravenous racemic ketamine (IV ketamine) have emerged as potential alternatives, but their comparative effectiveness and safety remain unclear due to limited evidence. We systematically...

The Association between Intranasal Esketamine and Treatment-emergent Insomnia in the Treatment of Treatment-resistant Major Depression: A Meta-analysis.

Clinical Psychopharmacology and Neuroscience August 31, 2025 Cagdas Türkmen, Rutger Boesjes, Anne-Fleur Zandbergen et al.

Intranasal (IN) esketamine represents a novel add-on treatment for treatment-resistant depression (TRD) with reported favourable effects on insomnia. IN esketamine treatment might similarly reduce the incidence of insomnia as an adverse event (AE). The present meta-analysis therefore investigated whether IN esketamine relative to placebo is associated with a lower incidence of insomnia as an AE...

Ketamine Therapy in Psychiatry: A Comprehensive Review

Journal of Psychiatric Nursing August 30, 2025 Asif Khan, Satyaveer *, Shrikant K. Nair et al.

Ketamine, traditionally known as an anesthetic agent, has garnered attention for its rapid acting antidepressant properties, particularly in patients with treatment resistant depression (TRD). The compound’s unique pharmacological profile primarily as an NMDA receptor antagonist has enabled its repositioning in psychiatric settings, where conventional antidepressants often fall short. This...

Ketamine infusion therapy in an elderly patient with complex regional pain syndrome and major depression

International Journal of Community Medicine and Public Health August 30, 2025 Parinda Parikh, Jeremy Kays, Zoe Gellert et al.

Complex regional pain syndrome (CRPS) is a chronic pain disorder that severely affects mobility and quality of life. This case report describes an 86-year-old man who has a long-standing history of CRPS-related back and leg pain. Traditional treatments, including opioids and duloxetine, did not improve his symptoms, and due to religious beliefs restricting specific interventions, standard...

Esketamine use in real-world clinical practice in patients with treatment-resistant depression.

European Psychiatry August 26, 2025 Ismaël Conejero, Raquel Alvarez García, Alejandro Porras-Segovia et al. 2 citations

Esketamine has been shown to produce a major antidepressant response in patients with treatment-resistant depression (TRD). We evaluated the factors associated with achieving remission in these individuals. The study was carried out across four psychiatry departments in Madrid, Spain. Patients aged over 18 years were included if they received esketamine as an augmentation treatment for TRD....

Ketamine to enhance methadone treatment retention in patients with opioid use disorder and co-morbid depression

The American Journal of Drug and Alcohol Abuse August 22, 2025 Peter Manza, Annabelle M. Belcher, Heather Fitzsimons et al.

ABSTRACT Background: Opioid use disorder (OUD) is a chronic relapsing condition with a high mortality rate. While medications such as methadone are valuable first-line therapies, retention is poor, with the highest dropout rates early in a treatment attempt. Poor outcomes are due in part to the very high rates of co-morbid depression in people with OUD, as depression can drive opioid use....

Synbiotic diet produces antidepressant-like effects but alters ketamine activity in an avian model of treatment-resistant depression

Behavioural Pharmacology August 21, 2025 Stephen W. White, Tara D. Clover, Kenneth J. Sufka

Pre- and probiotics promote a diverse and functional gut microbiota and have demonstrated both anxiolytic and antidepressant effects; however, how synbiotic diet interacts with antidepressant medications has not been fully investigated. This study sought to evaluate the potential anxiolytic or antidepressant effects of a synbiotic diet in an avian model that presents homologies with...
