Ketamine: a paradigm shift for depression research and treatment

Neuron March 1, 2019 John H. Krystal, Chadi G. Abdallah, Gerard Sanacora et al. 443 citations

Ketamine is the first exemplar of a rapid-acting antidepressant with efficacy for treatment-resistant symptoms of mood disorders. Its discovery emerged from a reconceptualization of the biology of depression. Neurobiological insights into ketamine efficacy shed new light on the mechanisms underlying antidepressant efficacy. The rapid, profound, and sustainable antidepressant effects of ketamine...

ELEctroconvulsive therapy (ECT) vs. Ketamine in patients with Treatment-resistant Depression: The ELEKT-D study protocol.

Contemporary Clinical Trials February 1, 2019 S. Mathew, S. Wilkinson, Murat Altinay et al. 54 citations

Major depressive disorder (MDD) is the most common mental illness and the leading cause of disability worldwide. Electroconvulsive therapy (ECT) is the most effective treatment for MDD and the gold-standard therapy for treatment-resistant depression (TRD), yet it remains underutilized due to factors such as limited availability, stigma, and concerns about cognitive side effects. Ketamine has...

Structural Plasticity Induced by Ketamine in Human Dopaminergic Neurons as Mechanism Relevant for Treatment-Resistant Depression

Chronic Stress 2019 Ginetta Collo, Laura Cavalleri, Emilio Merlo Pich

The mechanisms underlying the antidepressant effects of ketamine in treatment-resistant depression are only partially understood. Reactivation of neural plasticity in prefrontal cortex has been considered critical in mediating the effects of standard antidepressants, but in treatment-resistant depression patients with severe anhedonia, other components of the affected brain circuits, for...

Role of Actinobacteria and Coriobacteriia in the antidepressant effects of ketamine in an inflammation model of depression

Pharmacology, Biochemistry and Behavior 2019 Nian-nian Huang, Dongyu Hua, Gaofeng Zhan et al.

ABSTRACT Ketamine, an N‐methyl‐d‐aspartic acid receptor (NMDAR) antagonist, elicits rapid‐acting and sustained antidepressant effects in treatment‐resistant depressed patients. Accumulating evidence suggests that gut microbiota via the gut‐brain axis play a role in the pathogenesis of depression, thereby contributing to the antidepressant actions of certain compounds. Here we investigated the...

NMDA Antagonists for Treatment-Resistant Depression.

Handbook of experimental pharmacology 2019 Nuri B Farber

Fifteen to thirty percent of patients with major depressive disorder do not respond to antidepressants that target the monoaminergic systems. NMDA antagonists are currently being actively investigated as a treatment for these patients. Ketamine is the most widely studied of the compounds. A brief infusion of a low dose of this agent produces rapid improvement in depressive symptoms that lasts...

Repeat-dose ketamine augmentation for treatment-resistant depression with chronic suicidal ideation: A randomized, double blind, placebo controlled trial.

Journal of Affective Disorders 2019 Dawn F. Ionescu, Kate H Bentley, M. Eikermann et al. 179 citations

BACKGROUND Several studies indicate that ketamine has rapid antidepressant effects in patients with treatment-resistant depression (TRD). The extent to which repeated doses of ketamine (versus placebo) reduce depression in the short and long term among outpatients with TRD and chronic, current suicidal ideation remains unknown. METHODS Twenty-six medicated outpatients with severe major...

Efficacy of ketamine therapy in the treatment of depression

Indian Journal of Psychiatry 2019 Suprio Mandal, VinodKumar Sinha, Nishant Goyal 92 citations

BACKGROUND: Severe depressive disorder is among most debilitating condition. Conventional pharmacotherapy usually takes several weeks (usually 4-12 weeks) to improve symptoms. Ketamine is an N-methyl-D aspartate receptor antagonist having rapid action on depressive symptoms. OBJECTIVES: The effect of subanesthetic dose of ketamine was assessed on depressive and anxiety symptoms. Illness...
