The Role of Cannabis within an Emerging Perspective on Schizophrenia Jegason P. Diviant, Jacob M. Vigil, and Sarah S.

Carhart-Harris Neuropharmacology, 2018, 142, 263e269. https://doi.org/10.1016/j.neuropharm.2017.12.041 Abstract Recent evidence indicates that psilocybin with psychological support may be effective for treating depression. Some studies have found that patients with depression show heightened amygdala responses to fearful faces and there is reliable evidence that treatment with SSRIs attenuates amygdala responses (Ma, 2015). We hypothesised that amygdala responses to emotional faces would be altered post treatment with psilocybin. In this open-label study, 20 individuals diagnosed with moderate to severe, treatment-resistant depression, underwent two separate dosing [...]

Back Frontiers in Psychiatry, 2018, 1-10. doi : 10.3389/fpsyt.2018.00277 Abstract Background : Despite advances in behavioral and pharmacotherapy interventions, substance use disorders (SUDs) are frequently refractory to treatment. Glutamatergic dysregulation has received increasing attention as one common neuropathology across multiple substances of abuse. Ketamine is a potent N-methyl-D-aspartate (NMDA) glutamatergic receptor antagonist which has been found to be effective in the treatment of severe depression. Here we review the literature on the efficacy of ketamine in [...]
Lire la suiteFDA's Rapid Approval of Esketamine for Severe Depression Questioned Pauline Anderson Medscape, November 13, 2019 https://www.medscape.com/viewarticle/921248 While some experts have hailed intranasal esketamine (Spravato, Janssen) as a "game changer" for treatment-resistant depression (TRD), others are concerned over the US Food and Drug Administration's (FDA) rapid approval of the drug. Dr Erick Turner In an editorial published online October 31 in Lancet Psychiatry, Erick H. Turner, MD, who sits on one of the FDA advisory committees that recommended approval of Spravato, said the drug did not meet standard criteria for FDA approval and that there was little evidence to support its safety and efficacy based on data from [...]
Lire la suiteA Chocolate a Day Keeps Depression Away ? Megan Brooks, Laurie Barclay Medscape, 13 / 09 /2019 https://www.medscape.org/viewarticle/917963 Clinical Context Accumulating evidence suggests that dietary factors, such as eating chocolate, may affect depressive symptoms. The potential mood-enhancing properties of chocolate may relate to its orosensory properties, psychoactive ingredients, and activation of neural reward pathways. However, only a few studies have analyzed associations between chocolate consumption and depressive symptoms, with conflicting results. The goal of this analysis was to evaluate associations between chocolate consumption and depressive symptoms in a large, representative sample of US adults enrolled in the US National Health and Nutrition Examination Survey (NHANES) between [...]

In a review of scientific studies that analyzed the impact of medicinal cannabinoids on six mental health disorders, the researchers found “a lack of evidence for their effectiveness.” Their findings have important implications for countries such as the United States, Australia, Britain and Canada, where medical cannabis is being made available for patients with certain [...]
