Publicado por Elsevier España, S.L.U. All rights reserved. doi : 10.1016/j.nrl.2018.12.004 Abstract Drugs impact brain reward circuits, causing dependence and addiction, in a condition currently described as substance use disorders. Mechanisms of synaptic plasticity in these circuits are crucial in the development of addictive behaviour, and endocannabinoids, particularly anandamide and 2-arachidonyl-glycerol, participate in normal neuroplasticity. Substance use disorders are known to be associated with disruption of endocannabinoid-mediated synaptic plasticity, among other phenomena. Endocannabinoids mediate neuroplasticity in the short and the long term. In the short term, [...]

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 [...]

Société Psychédélique Française, novembre 2019 D’après l’Organisation mondiale de la santé, une personne sur quatre dans le monde sera affectée à un moment donné de sa vie par des troubles mentaux ou neurologiques. Or, après des décennies d’oubli, nous assistons en dehors de nos frontières à un regain de la recherche clinique psychothérapeutique sur les psychédéliques et au développement de thérapies novatrices impliquant ces substances. Les psychédéliques sont des composés, issus du monde vivant ou de la chimie, provoquant des effets analogues sur le psychisme [...]

Cannabis sativa (cannabis) is on of the oldest plants cultivated by men. Cannabidiol (CBD) is the major non-psychomimetic compound derived from cannabis. It has been proposed to have a therapeutic potential over a wide range of neuropsychiatric disorders. In this narrative review, we have summarized a selected number of pre-clinical and clinical studies, examining the effects of CBD in neuropsychiatric [...]
Lire la suiteWhy Psychiatry Needs 3,4 Methylenedioxymeth-amphetamine : A Child Psychiatrist’s Perspective Ben SESSA Neurotherapeutics, 2017, 14, (3), 741-749. doi:10.1007/s13311-017-0531-1 Abstract Since the late 1980s the psychoactive drug 3,4-methylenedioxymethamphetamine (MDMA) has had a well-known history as the recreationally used drug ecstasy. What is less well known by the public is that MDMA started its life as a therapeutic agent and that in recent years an increasing amount of clinical research has been undertaken to revisit the drug’s medical potential. MDMA has unique pharmacological properties that translate well to its proposed agent to assist trauma-focused psychotherapy. Psychological trauma—especially that which arises early in life from child abuse—underpins many [...]
Lire la suitePsychedelics as Medicines for Substance Abuse Rehabilitation : Evaluating Treatments with LSD, Peyote, Ibogaine and Ayahuasca Michael Winkelman Current Drug Abuse Reviews, 2014, 7, 101-116 Abstract : Substances known as psychedelics, hallucinogens and entheogens have been employed in ethnomedical traditions for thousands of years, but after promising uses in the 1950’s and 1960’s they were largely prohibited in medical treatment and human research starting in the 1970’s as part of the fallout from the war on drugs. Nonetheless, there are a number of studies which suggest that these substances have potential applications in the treatment of addictions. While these substances are generally classified as [...]
Lire la suiteClinical potential of psilocybine as a treatment for mental health conditions Jeremy Daniel & Margaret Haberman Mental Health Clinician, 2017, Vol. 7, No. 1, pp. 24-28 https://doi.org/10.9740/mhc.2017.01.024 Abstract Psilocybin, a classic hallucinogen, is a chemical produced by more than 100 species of mushrooms worldwide. It has high affinity for several serotonin receptors, including 5-HT1A, 5-HT2A, and 5-HT2C, located in numerous areas of the brain, including the cerebral cortex and thalamus. With legislation introduced in 1992, more work is being done to further understand the implications of psilocybin use in a number of disease states. Certain mental health disease states and symptoms have been studied, including [...]
