Cannabidiol attenuates haloperidol-induced catalepsy and c-Fos protein expression in the dorsolateral striatum via 5-HT1A receptors in mice, Andreza B. Sonego et al., 2016

Cannabidiol attenuates haloperidol-induced catalepsy and c-Fos protein expression in the dorsolateral striatum via 5-HT1A receptors in mice Andreza B. Sonego; Felipe V. Gomes; Elaine A. Del Bel; Francisco S. Guimaraes Behavioural Brain Research, 2016, 21. Doi : 10.1016/j.bbr.2016.04.042   Highlights  Cannabidiol (CBD) attenuated haloperidol-induced catalepsy.  CBD reduced c-Fos protein expression in the dorsal striatum induced by haloperidol.  CBD effects were blocked by 5-HT1A receptor antagonist.   Abstract Cannabidiol (CBD) is a major non-psychoactive compound from Cannabis sativa plant. Given that CBD reduces psychotic symptoms without inducing extrapyramidal motor side-effects in animal models and schizophrenia patients, it has been proposed to act as an atypical antipsychotic. In addition, CBD [...]

Acceptance of pharmaceutical cannabis substitution by cannabis using patients with schizophrenia, Jan van Amsterdam et al., 2018

Acceptance of pharmaceutical cannabis substitution by cannabis using patients with schizophrenia Jan van Amsterdam, Jojanneke Vervloet, Gerdien de Weert, Victor J. A. Buwalda, Anna E. Goudriaan and Wim van den Brink Harm Reduction Journal, 2018, 15, 47, 1-4. Doi : 10.1186/s12954-018-0253-7   Abstract Background : Cannabis-smoking patients with a psychotic disorder have poorer disease outcomes than non-cannabis-smoking patients with poorest outcomes in patients smoking high-potency cannabis (HPC) containing high Δ9-tetrahydrocannabinol (THC) and low cannabidiol (CBD). Quitting cannabis smoking or substitution of HPC by cannabis variants containing less THC and/or more CBD may benefit these patients. The present study explores whether daily HPC-smoking patients with schizophrenia accept smoking [...]

Adolescent Cannabis Use : What is the Evidence for Functional Brain Alteration ?, V. Lorenzetti et al., 2016

Adolescent Cannabis Use : What is the Evidence for Functional Brain Alteration ? V. Lorenzetti, S. Alonso-Lanaa, G. J. Youssef, A. Verdejo-Garcia, C. Suo, J. Cousijn, M. Takagi, M. Yücel and N. Solowij Current Pharmaceutical Design, 2016, 22, 1-14. DOI: 10.2174/1381612822666160805155922   Abstract Background : Cannabis use typically commences during adolescence, a period during which the brain undergoes profound remodeling in areas that are high in cannabinoid receptors and that mediate cognitive control and emotion regulation. It is therefore important to determine the impact of adolescent cannabis use on brain function. Objective : We investigate the impact of adolescent cannabis use on brain function by reviewing the functional [...]

Psychiatry & the psychedelic drugs. Past, present & future, James J.H. Rucker et al., 2018

Psychiatry & the psychedelic drugs. Past, present & future James J.H. Rucker, Jonathan Iliff, David J. Nutt Neuropharmacology, 2018, 142, 200e218 https://doi.org/10.1016/j.neuropharm.2017.12.040   a b s t r a c t The classical psychedelic drugs, including psilocybin, lysergic acid diethylamide and mescaline, were used extensively in psychiatry before they were placed in Schedule I of the UN Convention on Drugs in 1967. Experimentation and clinical trials undertaken prior to legal sanction suggest that they are not helpful for those with established psychotic disorders and should be avoided in those liable to develop them. However, those with so-called ‘psychoneurotic’ disorders sometimes benefited considerably from their tendency to [...]

Comment le cannabis peut favoriser les troubles psychotiques : conséquences, dépistage et prise en charge, Alain Dervaux, 2019

Comment le cannabis peut favoriser les troubles psychotiques : conséquences, dépistage et prise en charge Alain Dervaux L’Information Psychiatrique, 2019, 95, (8), 672-678 * Travail présenté aux 37es journées de la Société de l’Information Psychiatrique, Antibes, 4-6 octobre 2018. Résumé Les relations complexes entre cannabis et psychoses ont fait l’objet de nombreux travaux depuis une vingtaine d’années. La consommation de cannabis peut s’accompagner de symptômes psychotiques chez certains sujets (jusqu’à 15 % des consommateurs) qui disparaissent avec l’élimination du -9-THC de l’organisme. Elle peut aussi augmenter par deux le risque de troubles psychotiques, notamment de schizophrénie. Le risque est d’autant plus élevé que la consommation de cannabis [...]

Could cannabidiol be used as an alternative to antipsychotics ?, Marc Fakhoury, 2016

Could cannabidiol be used as an alternative to antipsychotics ? Marc Fakhoury Journal of Psychiatric Research · May 2016 Doi : 10.1016/j.jpsychires.2016.05.013   Abstract Schizophrenia is a mental disorder that affects close to 1% of the population. Individuals with this disorder often present signs such as hallucination, anxiety, reduced attention, and social withdrawal. Although antipsychotic drugs remain the cornerstone of schizophrenia treatment, they are associated with severe side effects. Recently, the endocannabinoid system (ECS) has emerged as a potential therapeutic target for pharmacotherapy that is involved in a wide range of disorders, including schizophrenia. Since its discovery, a lot of effort has been devoted to the [...]
