Ketamine is an effective intervention for treatment-resistant depression (TRD), including late-in-life (LL-TRD). The proposed mechanism of antidepressant effects of ketamine is a glutamatergic surge, which can be measured by electroencephalogram (EEG) gamma oscillations. Yet, non-linear EEG biomarkers of ketamine effects such as neural complexity are needed to capture broader systemic effects,...

Abstract Background Recent preclinical and clinical studies have shed light on the possible impact of sex and estrous/menstrual cycle on ketamine’s antidepressant action but with incongruous results. The preclinical studies that have shown the effects of ovarian sex hormones have not done so in animal models of depression. Thus, the aim of the present study is to scrutinize the acute behavioral...

Ketamine (KA), commonly used as an anesthetic, is now widely studied as an antidepressant for the treatment of depression. However, due to its side effects, such as addiction and cognitive impairment, the dosage and frequency of (S)‐ketamine approved by the FDA for the treatment of refractory depression is very low, which limits its efficacy. Here, a new multifunctional nanocarrier system...

: Treatment-resistant depression is a common psychiatric disorder that can lead to significant disability and decreased quality of life for patients. In recent years, there has been growing interest in the combination of intravenous ketamine and electroconvulsive therapy (ECT) for the treatment of treatment-resistant depression. Ketamine is an anesthetic that is an N-methyl-D-aspartate (NMDA)...

Although consensus in the field is lacking, the most common definition for treatment-resistant depression (TRD) requires a minimum of 2 prior treatment failures with confirmed adequate dose and duration. This article presents a clinical example of TRD in a patient with a long history of depression and inadequate response to treatment. The prominent feature is the patient's persistent...

BACKGROUND For individuals with treatment-resistant depression (TRD), transcranial magnetic stimulation (TMS) has become a well-established approach. In the past decade, intravenous (IV) racemic ketamine has also emerged as a potential treatment for TRD. Currently, little data is available on the clinical effects of IV racemic ketamine in TRD patients who experienced TMS-failure. METHODS...

Background: Depression is a debilitating disease with a high socioeconomic burden. Regular antidepressants usually require several weeks to ameliorate symptoms; however, numerous patients do not achieve remission. What is more, sleep disturbances are one of the most common residual symptoms. Ketamine is a novel antidepressant with rapid onset of action with a proven antisuicidal effect. Little...

INTRODUCTION Ketamine treatment prompts a rapid antidepressant response in treatment-resistant depression (TRD). We performed an exploratory investigation of how ketamine treatment in TRD affects different cognitive domains and relates to antidepressant response. METHODS Patients with TRD (N = 66; 30 M/35F; age = 39.5 ± 11.1 years) received four ketamine infusions (0.5 mg/kg). Neurocognitive...

The relationship between subjective drug experience and antidepressant outcomes for ketamine derivatives is poorly understood but of high clinical relevance. Esketamine is the patented (S)-enantiomer of ketamine and has regulatory approval for psychiatric applications. We examined the relationship between acute dissociation, as measured by the Clinician-Administered Dissociative States Scale...

Deficiencies in standard of care antidepressants are driving novel drug discovery. A new age of antidepressant medications has emerged with the introduction of rapid-acting antidepressants with efficacy in treatment-resistant patients. The newly approved medicines and those in clinical development for major depressive disorder (MDD) are documented in this scoping review of newly approved and...
