Activity-dependent neuroprotective protein (ADNP) syndrome is a rare neurodevelopmental disorder resulting in intellectual disability, developmental delay and autism spectrum disorder (ASD) and is due to mutations in the ADNP gene. Ketamine treatment has emerged as a promising therapeutic option for ADNP syndrome, showing safety and apparent behavioral improvements in a first open label study....
Studies have confirmed the rapid antidepressant action of ketamine in depressive episodes. Nevertheless, a standardized procedure for the delivery of ketamine infusion in individuals suffering from treatment-resistant depression, particularly in terms of infusion frequency and total dosage, remains undetermined. In addition, an efficacious ketamine regimen for persistent pain management...
Background: Low doses of different ketamine enantiomers have demonstrated rapid behavioural and biological actions in animals with depressive-like behavior. However, some authors report different effects depending on model of depression and ketamine isomer used. Objective: Our primary aim was to evaluate the effect of ketamine enantiomers on depressive-like behavior, anhedonic-like behavior and...
Participants who received ketamine at the NIMH were among the first to receive ketamine for depression in controlled clinical trials, providing a unique opportunity to assess long-term outcomes. This analysis evaluated the relationship between participating in a ketamine clinical trial and subsequent ketamine/esketamine use after leaving the research setting. Participants seen within the NIMH...
The discovery of racemic (R, S)-ketamine as a rapid-acting antidepressant and the subsequent FDA approval of its (S)-enantiomer, esketamine, for treatment-resistant depression (TRD) are significant advances in the development of novel neuropsychiatric therapeutics. Esketamine is now recognized as a powerful tool for addressing persistent symptoms of TRD compared to traditional oral...
The anesthetic, analgesic and antidepressant drug ketamine produces dissociation with symptoms of psychosis and anxiety, an effect attributed to neuronal nitric oxide depletion following N-methyl-d-aspartate blockade. There is evidence that dissociation induced by racemic ketamine, containing both ketamine enantiomers (S- and R-ketamine) but not esketamine (the S-isomer) is inhibited by nitric...
Introduction: Ketamine has been shown to have rapid antidepressant effects. In addition, the use of EEG in depression offers a new approach to diagnose patients. It is necessary to understand locational-based EEG and MEG changes following ketamine in patients with depression to establish a potential biomarker panel. This study sought to identify consistent changes in band power as well as to...
Ketamine, a dissociative anesthetic, is widely utilized in both human and veterinary anesthesia. Its (S)-enantiomer, esketamine, is similarly employed for anesthesia and analgesia. The anesthetic effects of both ketamine and esketamine arise from their antagonism of the N-methyl-D-aspartate receptor (NMDAR). In field of psychiatry, the rapid-acting antidepressant properties of ketamine for...

In spite of the variety of antidepressant drugs available for treating depressive disorder, treatment resistant depression (TRD) is still prevalent among the population. Despite being used mainly in anesthesia, and mostly phased out by more modern anesthetics, ketamine shows potential when it comes to depressive disorder treatment. We've set out to investigate the the relevant body of work to...
Background: Low-dose ketamine infusion has been demonstrated to exert antisuicidal effects on patients with treatment-resistant depression (TRD) and strong suicidal ideation. Although evidence suggests an association between hopelessness and suicidality, very few studies have investigated the antihopelessness effects of ketamine. Methods: This study included 84 patients with TRD and strong...
