Treatments for depression in bipolar disorder (BD) are far less well developed than for unipolar major depressive disorder. Several innovative and experimental approaches have been emerging recently, including use of the dissociative anesthetic ketamine and other antagonists of central NMDA glutamate receptors, as well as unsaturated fatty acids, anti-inflammatory agents, and possibly probiotic...

Considerable recent attention has focused on the rapid antidepressant effects observed in treatment resistant patients produced by the NMDA receptor antagonist, ketamine. Surprisingly, the effects of ketamine in the context of stressor exposure, as well as the consequences of its chronic use are unclear. Thus, we assessed the impact of acute and repeated ketamine treatment together with acute...

Several pro-inflammatory cytokines have been implicated in depression and in antidepressant response. This exploratory analysis assessed: 1) the extent to which baseline cytokine levels predicted positive antidepressant response to ketamine; 2) whether ketamine responders experienced acute changes in cytokine levels not observed in non-responders; and 3) whether ketamine lowered levels of...

Over the past decade, ketamine has been studied for major depressive disorder and bipolar depression. Ketamine is believed to exert its antidepressant properties through N-methyl-D-aspartate receptor antagonism. Study authors completed a literature review of seven randomized controlled trials of ketamine usage in major depressive disorder and bipolar depression. Ketamine demonstrated a...

Major depressive disorder is a severe and complex mental disorder. Impaired neurotransmission and disrupted signalling pathways may influence neuroplasticity, which is involved in the brain dysfunction in depression. Traditional neurobiological theories of depression, such as monoamine hypothesis, cannot fully explain the whole picture of depressive disorders. In this review, we discussed new...

Objective To evaluate feasibility, efficacy and tolerability of Sudarshan Kriya yoga (SKY) as an adjunctive intervention in patients with major depressive disorder (MDD) with inadequate response to antidepressant treatment. Method Patients with MDD (defined by DSM-IV-TR) depressed despite ≥8 weeks of antidepressant treatment were randomized to SKY or a waitlist control (delayed yoga) arm for 8...

Psilocybin, a psychoactive component of magic mushrooms, is thought to have therapeutic potential in psychiatric disorders but its mechanism of action within the brain is unclear. In a study, researchers gave two doses of psilocybin to 19 patients with treatment-resistant depression, and studied blood flow within the brain using functional magnetic resonance imaging (MRI) at […]

<b><i>Introduction:</i></b> Ketamine has shown rapid though short-lived antidepressant effects. The possibility of concerning neurobiological changes following repeated exposure to the drug motivates the development of strategies that obviate or minimize the need for longer-term treatment with ketamine. In this open-label trial, we investigated whether cognitive behavioral therapy (CBT) can...
