Anhedonia, defined as a significant loss of interest or pleasure, is one of the core symptoms of treatment- resistant depression (TRD) and is often associated with poor prognosis. This article primarily investigates the changes in anhedonia symptoms, inflammatory markers, and cortisol levels in TRD patients after low-dose esketamine treatments. A total of sixty patients with TRD were enrolled...

As the diagnosis rate of depression continues to rise, effective treatment options for this condition have become one of the most researched areas in the field. Earlier antidepressants were primarily developed based on mechanisms that involve regulating imbalanced neurotransmitters. For example, the widely known Selective Serotonin Reuptake Inhibitors (SSRIs) and various tricyclic...

Improving safe and effective access to ketamine therapy is of high priority given the growing burden of mental illness. Telehealth-supported administration of sublingual ketamine is being explored toward this goal. In this longitudinal study, moderately-to-severely depressed patients received four doses of ketamine at home over four weeks within a supportive digital health context. Treatment...

Major depressive disorder (MDD) and posttraumatic stress disorder (PTSD) are debilitating psychiatric conditions associated with poor health outcomes similarly observed in non-pathological aging. Ketamine is a dissociative anesthetic and NMDA receptor antagonist with demonstrated rapid reduction in symptoms associated with Treatment Resistant Depression (TRD) and PTSD. Ketamine’s effects on...

Dear Editor, Ketamine is used off-label for indications ranging from depression to chronic pain. We know of no report of the successful use of oral ketamine, administered without psychotherapy, for complex posttraumatic stress disorder (cPTSD).[1,2] We describe a patient with chronic depression and cPTSD who failed >30 previous interventions but had dramatic and persistent relief from chronic...

About one-third of patients with depression do not achieve adequate response to current treatment options. Although intravenous and intranasal administrations of (es)ketamine have shown antidepressant properties, their accessibility and scalability are limited. We investigated the efficacy, safety, and tolerability of generic oral esketamine in patients with treatment-resistant depression (TRD)...

Over 300 million people worldwide suffer from major depressive disorder (MDD). Unfortunately, only 30-40% of patients with MDD achieve complete remission after conventional monoamine antidepressant therapy. In recent years, ketamine has revolutionized the treatment of MDD, with its rapid antidepressant effects manifesting within a few hours as opposed to weeks with conventional antidepressants....

We conducted a systematic review and meta-analysis to investigate the comparative effectiveness of ketamine versus electroconvulsive therapy (ECT) for the treatment of major depressive episodes (MDEs). PubMed, EMBASE and Cochrane Library databases were systematically searched for randomized controlled trials (RCTs) comparing ketamine and ECT for MDE. The primary outcome was response rate, for...

Ketamine, an N-methyl-D-aspartate receptor antagonist, is a racemic mixture of esketamine and arketamine used to treat unipolar and bipolar depression. Preliminary reports indicate that it may be beneficial for depressed patients reporting symptoms of anhedonia. In this systematic review we aim to assess and analyze the existing body of evidence regarding the therapeutic effects of ketamine on...

Electroconvulsive shocks (ECS) and ketamine are antidepressant treatments with a relatively fast onset of therapeutic effects compared to conventional medication and psychotherapy. While the exact neurobiological mechanisms underlying the antidepressant response of ECS and ketamine are unknown, both interventions are associated with neuroplasticity. Restoration of neuroplasticity may be a...
