About a third of patients suffering from major depression develop treatment-resistant depression (TRD). Although repetitive transcranial magnetic stimulation (rTMS) and intravenous ketamine have proven effective for the management of TRD, many patients remain refractory to treatment. We present the case of a patient suffering from bipolar TRD. The patient was referred to us after failure to...

Anorexia nervosa (AN) is a mental illness with the highest rates of mortality and relapse, and no approved pharmacological treatment. Using an animal model of AN, called activity‐based anorexia (ABA), we showed earlier that a single intraperitoneal injection of ketamine at a dose of 30 mg/kg (30mgKET), but not 3 mg/kg (3mgKET), has a long‐lasting effect upon adolescent females of ameliorating...

Nitrous oxide (N2O; laughing gas) has recently been reported as a putative rapid-acting antidepressant, but little is known about the underlying mechanisms. We performed transcriptomics, in situ hybridization, and electrophysiological studies to examine the potential shared signatures induced by 1 h inhalation of 50% N2O and a single subanesthetic dose of ketamine in the medial prefrontal...

Ketamine is a common medical anesthetic and analgesic but is becoming more widely used as a recreational drug. Significant side effects on the urinary tract are associated with frequent recreational ketamine use most notably ketamine-induced cystitis (KIC). Regular ketamine consumption has been shown to increase the risk of cystitis symptoms by 3- to 4-fold, and cessation of ketamine use is...
Ketamine Revisited - New Insights into NMDA Inhibitors

Electroconvulsive therapy (ECT) is highly effective both Major Depressive Disorder (MDD) and Bipolar Disorder (BD). Ketamine, an antagonist of the N-Methyl-D-aspartate receptor, has been described to have antidepressant properties. There is a hypothesis that ECT performed with anesthesia using ketamine is more effective than conventional ECT. Also, although ECT is the gold standard for BD and...

Ketamine is a phencyclidine derivative and N-methyl-D-aspartate receptor antagonist, widely popular as a dissociative anesthetic. Its use as an anesthetic in humans was progressively fallen out due to its associated adverse effects and the emergence of newer and safer anesthetics. In recent few decades, various reports related to its efficacy in the treatment of resistant depression with...

Sensory systems need to process signals in a highly dynamic way to efficiently respond to variations in the animal’s environment. For instance, several studies showed that the visual system is subject to neuroplasticity since the neurons’ firing changes according to stimulus properties. This dynamic information processing might be supported by a network reorganization. Since antidepressants...

Our knowledge regarding pathological and treatment resistance mechanisms involved in depression is far from understood. Sexual dimorphism in this topic is well acknowledged. However, the need to highlight sex-based discrepancies is unmet. Ketamine, the dissociative anesthetic, has emerged as a rapid antidepressant. This chapter reviewed sexual dimorphism in pharmacological and genetic models of...

Ketamine has been extensively used in the medical field for more than 50 years, but its exact mechanism of action remains unknown. It’s used to induce dissociative anesthesia (a state of profound analgesia, amnesia with light sleep, immobility, and a sense of disassociation from one’s own body and surroundings). Clinical studies on ketamine as a dissociative anesthetic, a model for psychosis,...

Ketamine is a derivative of phencyclidine with unique anesthetic, analgesic, as well as antidepressant pharmacological properties. Despite its clinical use, ketamine is classified on the list with new psychoactive substances having psychedelic properties. The abuse trend of ketamine increasing globally, and it became a common club drug over the past few decades. Of note, recreational use of...
