Effects of GABA-B receptor positive modulator on ketamine-induced psychosis-relevant behaviors and hippocampal electrical activity in freely moving rats.

Psychopharmacology October 2017 Jingyi Ma, L Stan Leung

Decreased GABAB receptor function is proposed to mediate some symptoms of schizophrenia. In this study, we tested the effect of CGP7930, a GABAB receptor positive allosteric modulator, on ketamine-induced psychosis-relevant behaviors and hippocampal electrical activity in behaving rats. Electrodes were bilaterally implanted into the hippocampus, and cannulae were placed into the lateral...

Ketamine's dose-related effects on anxiety symptoms in patients with treatment refractory anxiety disorders.

Journal of Psychopharmacology October 2017 Paul Glue, Natalie J. Medlicott, Sarah Harland et al.

The N-methyl-D-aspartate receptor antagonist ketamine has rapid onset activity in treatment-resistant depression, post-traumatic stress disorder and obsessive compulsive disorder. Due to similarities in brain network activity in depression and anxiety disorders, we hypothesized that ketamine might also be active in other refractory anxiety disorders. We evaluated the efficacy and safety of...

[Biomarkers for Mood Disorders and a Novel Antidepressant (R)-ketamine].

Brain and nerve = Shinkei kenkyu no shinpo October 2017 Kenji Hashimoto

Depression is often misdiagnosed as major depressive disorder in patients with bipolar disorder. Therapeutic drugs for these two disorders are quite different, but the anesthetic ketamine shows fast-acting antidepressant effects in treatment-resistant patients with these disorders. Here, we discuss biomarkers for both disorders, recent findings regarding ketamine, and predictable biomarkers for...

Dreamless: the silent epidemic of REM sleep loss.

Annals of the New York Academy of Sciences October 1, 2017 Rubin Naiman

We are at least as dream deprived as we are sleep deprived. Many of the health concerns attributed to sleep loss result from a silent epidemic of REM sleep deprivation. REM/dream loss is an unrecognized public health hazard that silently wreaks havoc with our lives, contributing to illness, depression, and an erosion of consciousness. This paper compiles data about the causes and extent of...

Effect of ketamine dose on self-rated dissociation in patients with treatment refractory anxiety disorders

Journal of Psychopharmacology October 1, 2017 Cameron Castle, Andrew Gray, Shona Neehoff et al. 20 citations

Patients receiving ketamine for refractory depression and anxiety report dissociative symptoms in the first 60 min post-dose. The most commonly used instrument to assess this is the Clinician-Administered Dissociative States Scale (CADSS), developed based on the assessment of patients with dissociative symptoms. Its psychometric properties for ketamine-induced dissociation have not been...

Exploring Thematic Nightmare Content and Associated Self-Harm Risk.

Suicide and Life-Threatening Behavior September 28, 2017 Kevin D Hochard, Sam Ashcroft, Janine Carroll et al.

Nightmares have been shown to be robust predictors of self-harm risk, beyond depressive symptoms and hopelessness at times. However, few studies have investigated associations between nightmare content and increased self-harm risk. This study explored associations of thematic nightmare content with history of self-harm, and risk of self-harm phenomena the morning following a nightmare. A...

The Use of Virtual Reality Facilitates Dialectical Behavior Therapy® “Observing Sounds and Visuals” Mindfulness Skills Training Exercises for a Latino Patient with Severe Burns: A Case Study

Frontiers in Psychology September 25, 2017 J. Gómez, H. Hoffman, Steven L. Bistricky et al.

Sustaining a burn injury increases an individual's risk of developing psychological problems such as generalized anxiety, negative emotions, depression, acute stress disorder, or post-traumatic stress disorder. Despite the growing use of Dialectical Behavioral Therapy® (DBT®) by clinical psychologists, to date, there are no published studies using standard DBT® or DBT® skills learning for...

Ketamine: New Use for an Old Hat

Journal of Clinical Anesthesia and Pain Management September 22, 2017 Khidr Hassan, S El-Mallakh Rif

Depression is one of the leading causes of disability not only in the US but worldwide as well. It is ranked third for global disease burden by the WHO and estimated to affect 350 million people worldwide. The economic burden of depression is estimated to have increased by 21.5% from 2005 to 2010 (from $173.2 billion to $210.5 billion).

Psychedelic Drugs in Biomedicine

TIPS - Trends in Pharmacological Sciences September 22, 2017 Evan J. Kyzar, Charles D. Nichols, Raul R. Gainetdinov et al. 155 citations

Psychedelic drugs, such as lysergic acid diethylamide (LSD), mescaline, and psilocybin, exert profound effects on brain and behavior. After decades of difficulties in studying these compounds, psychedelics are again being tested as potential treatments for intractable biomedical disorders. Preclinical research of psychedelics complements human neuroimaging studies and pilot clinical trials,...

Ketamine: differential neurophysiological dynamics in functional networks in the rat brain.

Translational Psychiatry September 19, 2017 A Ahnaou, H Huysmans, R Biermans et al.

Recently, the N-methyl-d-aspartate-receptor (NMDAR) antagonist ketamine has emerged as a fast-onset mechanism to achieve antidepressant activity, whereas its psychomimetic, dissociative and amnestic effects have been well documented to pharmacologically model schizophrenia features in rodents. Sleep-wake architecture, neuronal oscillations and network connectivity are key mechanisms supporting...
