Development of Ketamine Administration as a Treatment for Chronic PTSD, Abigail B. Collins et al., 2020

Development of Ketamine Administration as a Treatment for Chronic PTSD Abigail B. Collins, BS; Sarah B. Rutter, MA; and Adriana Feder, MD Psychiatric Annals, 2020, 50, (2), 68-76. doi : 10.3928/00485713-20200109-01   ABSTRACT Posttraumatic stress disorder (PTSD) is a highly prevalent, chronic, and dis-abling condition for which currently available pharmacotherapies are insuf-ficiently effective. Ketamine, which is a glutamate N-methyl-D-aspartate (NMDA) receptor antagonist, has emerged as a promising and rapid-act-ing novel treatment intervention for this disorder. Findings from a proof-of-concept, randomized, controlled cross-over study of single-dose intravenous ketamine administration (compared to single-dose midazolam) in patients with chronic PTSD suggest that ketamine is associated with rapid improvement in [...]

How Cannabis-Based Therapeutics Could Help Fight COVID Inflammation, Liz Scherer, 2020

How Cannabis-Based Therapeutics Could Help Fight COVID Inflammation Liz Scherer Medscape.com, November 03, 2020   Editor's note: Find the latest COVID-19 news and guidance in Medscape's Coronavirus Resource Center. Plagued by false starts, a few dashed hopes, but with perhaps a glimmer of light on the horizon, the race to find an effective treatment for COVID-19 continues. At last count, more than 300 treatments and 200 vaccines were in preclinical or clinical development (not to mention the numerous existing agents that are being evaluated for repurposing). There is also a renewed interest in cannabinoid therapeutics — in particular, the nonpsychoactive agent cannabidiol (CBD) and the prospect of [...]

Psilocybin Delivers ‘Remarkable’ Relief in Severe Depression, Batya Swift Yasgur, 2020

Psilocybin Delivers 'Remarkable' Relief in Severe Depression Batya Swift Yasgur, MA, LSW Medscape.com, November 05, 2020   Psilocybin, the psychedelic compound in "magic mushrooms," rapidly improves symptoms and produces remission in as little as two sessions for patients with major depression, new research suggests. Results of a small randomized trial showed that treatment with psilocybin was associated with a greater than 50% reduction in depressive symptoms in 67% of study participants. In addition, 71% showed improvement at 4-week follow-up, with more than 50% achieving remission. "The finding that the majority of people whom we treated showed efficacy was quite a remarkable and gratifying finding and really sets the [...]

Use of Genetically Informed Methods to Clarify the Nature of the Association Between Cannabis Use and Risk for Schizophrenia, Nathan A. Gillespie, Kenneth S. Kendler, 2020

Use of Genetically Informed Methods to Clarify the Nature of the Association Between Cannabis Use and Risk for Schizophrenia Nathan A. Gillespie, Kenneth S. Kendler JAMA Psychiatry,  Published online November 4, 2020   Cohort studies and meta-analyses have documented a robust association between cannabis use, heavy use, and misuse with future risk of schizophrenia.1-3 Despite adjusting for covariates, including current psychotic symptoms, other psychopathology, and social integration,(1) the ability of these models to determine the degree to which cannabis causes schizophrenia is limited and dependent on their ability to capture all relevant confounders. When evaluating efforts to reduce cannabis use as a means of [...]

Effects of Psilocybin-Assisted Therapy on Major Depressive Disorder. A Randomized Clinical Trial, Alan K. Davis et al., 2020

Effects of Psilocybin-Assisted Therapy on Major Depressive Disorder. A Randomized Clinical Trial Alan K. Davis, PhD; Frederick S. Barrett, PhD; Darrick G. May, MD; Mary P. Cosimano, MSW; Nathan D. Sepeda, BS; Matthew W. Johnson, PhD; Patrick H. Finan, PhD; Roland R. Griffiths, PhD JAMA Psychiatry, 2020, E1-E9. doi : 10.1001/jamapsychiatry.2020.3285   IMPORTANCE : Major depressive disorder (MDD) is a substantial public health burden, but current treatments have limited effectiveness and adherence. Recent evidence suggests that 1 or 2 administrations of psilocybin with psychological support produces antidepressant effects in patients with cancer and in those with treatment-resistant depression. OBJECTIVE : To investigate the effect of psilocybin [...]

Psychedelics as a Treatment for Alzheimer’s Disease Dementia, Simon Andrew Vann Jones and Allison O’Kelly, 2020

Psychedelics as a Treatment for Alzheimer’s Disease Dementia Simon Andrew Vann Jones and Allison O’Kelly Cornwall Partnership NHS Foundation Trust, Liskeard, United Kingdom Frontiers in Synaptic Neuroscience, August 2020 | Volume 12 | Article 34 doi : 10.3389/fnsyn.2020.00034   Currently, there are no disease-modifying treatments for Alzheimer’s disease (AD) or any other dementia subtype. The renaissance in psychedelic research in recent years, in particular studies involving psilocybin and lysergic acid diethylamide (LSD), coupled with anecdotal reports of cognitive benefits from micro-dosing, suggests that they may have a therapeutic role in a range of psychiatric and neurological conditions due to their potential to stimulate neurogenesis, provoke neuroplastic [...]

Minor Cannabinoids of Cannabis sativa L., Fabian Thomas & Oliver Kayser, 2019

Minor Cannabinoids of Cannabis sativa L. Fabian Thomas & Oliver Kayser Journal of Medical Science, 2019, 88, (3), 141-149. Doi : 10.20883/jms.367   ABSTRACT Cannabinoids from Cannabis sativa L. play an important role as natural products in clinics. The major cannabinoids compromise tetrahydrocannabinolic acid (THCA) and cannabidiolic acid (CBDA) and its decarboxylated analogs. In this review, we focus on often neglected minor cannabinoids and discuss biosynthetic and chemical degradation routes to other neglected cannabinoids in Cannabis sativa starting from THCA, CBDA and cannabichromenic acid (CBCA). Based on the literature, patents and scientific reports, essential routes for the chemical modifi cation of cannabinoids are discussed to explain [...]
