Repeated exposure to ketamine leads to mental behavioral disorders and cognitive deficits in mice. As a neurotransmitter receptor, dopamine receptor 1 (DRD1) is involved in mental regulation and memory formation. However, the role of DRD1 in ketamine's behavioral disorder and neurotoxicity remains unclear. We found that seven-day ketamine exposure induced anxiety-like, depressive-like behavior...
Intravenous (IV) ketamine is an emerging intervention for treatment-resistant depression (TRD), yet the temporal dynamics of response and the optimal number of infusions remain unclear, particularly in real-world clinical populations with psychiatric comorbidities. We conducted a retrospective chart review of 209 adults with TRD treated with IV ketamine at an interventional psychiatry program....
The postpartum period is notorious for rapid and profound changes for birthing individuals and their families. Significant shifts to hormonal and physical health, routines and family roles, and the salience of personal and community risk factors all contribute to potential psychiatric and psychological distress for parents, sometimes diagnosed as a postpartum mood or anxiety disorder (PMAD)....
Objectives: Schizophrenia (SCZ) is characterized by significant impairments in perception and cognitive flexibility. Making accurate plans for therapy demands a deeper comprehension of the brain mechanisms behind these disorders. The purpose of our investigation is to analyze the protective effects of papaverine, a phosphodiesterase-10 inhibitor, on ketamine-induced SCZ -like behavioral and...
Surgical stress can lead to postoperative anxiety and depression, especially in adolescents. These complications reduce quality of life and increase medical burdens, but perioperative psychological interventions for adolescents are limited, and related mechanisms remain unclear. Esketamine (S-ketamine), an N-methyl-D-aspartate receptor (NMDAR) antagonist, has analgesic, sedative,...
Ketamine is a dissociative anesthetic with potential for treating mood, anxiety, and related disorders; however, concerns have emerged regarding hepatotoxicity in the context of chronic treatment. Systematic searches of PubMed, Scopus, and Ovid databases were conducted from inception to August 2025. Eligible studies included randomized controlled trials (RCTs), observational studies, and case...

Postoperative pain is the most notable issue after cesarean section (CS). The contributing factors include hyperalgesia, anxiety, depression, sleep disorders, and inflammation. In this study, we explored the effects of esketamine on pain, hyperalgesia, depression, anxiety, sleep disorders, and inflammation after CS. This randomized, blinded, controlled trial enrolled single-term pregnant women...
Intranasal esketamine has proven its worth for patients whose depression will not yield to standard medicines, yet the realities of cost and clinic-based monitoring bar many people from long-term use. The situation is especially frustrating for those who respond spectacularly to a first dose only to watch the benefits fade when they can no longer afford repeat treatments.That was the...

Relevant to the study of neurodevelopmental disorders, maternal immune activation (MIA) models reproduce the high incidence of anxiety disorders and molecular alterations in the cerebellum reported in patients with schizophrenia and autism. In parallel, ketamine, a fast-acting antidepressant, has shown beneficial effects in psychiatric disorders with immune-related components. To investigate...

This randomized, double-blind, parallel-group trial evaluated the efficacy of a single intravenous dose of esketamine (0.3mg/kg) administered at anesthesia induction in reducing postoperative depression and anxiety among patients undergoing cardiac valve surgery. A total of 142 patients from three centers were randomly assigned to receive esketamine or saline. The primary outcomes were the...
