<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...

OBJECTIVE: Insomnia and disrupted sleep are associated with increased risk of suicide. The N-methyl-d-aspartate antagonist ketamine has been associated with reduced suicidal thoughts, but the mechanism of action is unknown. This study sought to evaluate differences in nocturnal wakefulness in depressed individuals who did and did not have an antisuicidal response to ketamine. METHODS:...

Little is known about the antidepressive effects of repeated intravenous ketamine infusions beyond the acute phase of treatment in patients with refractory depression. Twelve subjects with treatment-resistant non-psychotic unipolar or bipolar major depression and suicidal ideation were given repeated (up to 6) thrice-weekly acute-phase intravenous infusions of ketamine (0.5mg/kg, administered...

Major depression is a serious psychiatric disorder and remains a leading cause of disability worldwide. Conventional antidepressants take at least several weeks to achieve a therapeutic response and this lag period has hindered their ability to attain beneficial effects in depressed individuals at high risk of suicide. The non-competitive N-methyl-D-aspartate glutamate receptor antagonist...

Objective - In our case report we present the treatment of a female patient suffering from therapy resistant depression. This procedure is not in practice in Hungary at present, the aim of our work to reproduce the findigs of international studies in domestic circumstances. Matter - Major depression is a common, chronic and severe mental disorder, with 16.2% lifetime prevalence. Many...

Male Sprague–Dawley rats were exposed to social defeat and subordination by aggressive male Long–Evans rats. The social defeat procedure involved the continuous exposure to an aggressive resident for 10 days, while living in a protective cage within the resident’s home cage with daily brief confrontations. These stress experiences resulted in 1) reduced body weight; 2) decreased social...

Background: The neurovascular plasticity of hippocampus is an important theory underlying major depression. Ketamine as a novel glutamatergic antidepressant drug can induce a rapid antidepressant effect within hours. In a mechanistic proof of this concept, we examined whether ketamine leads to an increase in synaptogenesis and vascularization within 24 hours after a single injection in a...

Preclinical Research The emergence of rapid-acting antidepressants such as ketamine has motivated studies aiming to reveal the molecular mechanism of the ketamine antidepressant effect and to enable the clinical application of rapid-acting antidepressants. Here, we provide an overview of studies addressing the antidepressant effects of ketamine in depressed patients and animal models of...

Glutamatergic system and the structural plasticity hypothesis are principal components for rapid and sustained antidepressant effects of novel antidepressant therapeutics. This study represents the first investigation of the structural plasticity of the hippocampus as one of the main contributed mechanisms to the sustained anti-depressive effect of ketamine. Flinders Sensitive Line (FSL) and...
