How Adolescents with Autism Spectrum Disorder (ASD) Spontaneously Attend to Real-World Scenes : Use of a Change Blindness Paradigm Michal Hochhauser, Adi Aran, Ouriel Grynszpan Journal of Autism and Developmental Disorders, 2018, 48, 502–510 DOI 10.1007/s10803-017-3343-6 https://www.researchgate.net/publication/320647151_How_Adolescents_with_Autism_Spectrum_Disorder_ASD_Spontaneously_Attend_to_Real-World_Scenes_Use_of_a_Change_Blindness_Paradigm [accessed Jul 16 2019].   Abstract Visual attention of adolescents with autism spectrum disorder (ASD) was assessed using a change blind-ness paradigm. Twenty-five adolescents with ASD aged 12–18 years and 25 matched typically developing (TD) adolescents viewed 36 pairs of digitized real-world images. Each pair of images was displayed in a ‘flicker paradigm’ whereby a particular item alternately appeared and disappeared. This item was either a central or a marginal [...]

Ibogaine and Subjective Experience: Transformative States and Psychopharmacotherapy in the Treatment of Opioid Use Disorder, Thomas K. Brown et al., 2019

Ibogaine and Subjective Experience : Transformative States and Psychopharmacotherapy in the Treatment of Opioid Use Disorder Thomas K. Brown, PhDa, Geoff E. Noller, PhDb, and Julie O. Denenberg, MAc Journal of Psychoactive Drugs, 2019 https://doi.org/10.1080/02791072.2019.1598603 ABSTRACT This article examines the therapeutic potential of ibogaine, a powerful oneiric alkaloid derived from Tabernanthe iboga, through exploring the subjective experiences of 44 participants from two observational treatment studies for opioid use disorder. Following treatment with ibogaine HCl, the participants (Mexico, n = 30; New Zealand, n = 14) completed the States of Consciousness Questionnaire (SCQ) to quantify the magnitude of their psychotropic experience. Participants were asked to provide [...]

Utilisation du Dronabinol (Marinol®) en France, Sarah Lejczak, RESPADD – GRECC, juin 2019

UTILISATION DU DRONABINOL (MARINOL ®) EN FRANCE Dr Sarah Lejczak AH, CETD, CHU Nantes sarah.lejczak@chu-nantes.fr 20.06.2019     Utilisation du Marinol en France : enquête auprès des prescripteurs Sarah Lejczak CHU de Nantes Sarah Lejczak, médecin algologue, rappelle qu’il est possible de prescrire du Marinol depuis 2006. Le premier essai clinique sur le cannabis thérapeutique a été réalisé au XIXe siècle, avec des patients atteints de choléra et de tétanos. Ces essais ont été suivis de dérives et de périodes de prohibition. Fort heureusement, des équipes de chercheurs se sont de nouveau emparées de ce sujet à partir des années 1970. Aux États-Unis, l’approche de ce sujet diverge selon les États. [...]

Improved Social Interaction, Recognition and Working Memory with Cannabidiol Treatment in a Prenatal Infection (poly I:C) Rat Model, Ashleigh L. Osborne, 2017

Improved Social Interaction, Recognition and Working Memory with Cannabidiol Treatment in a Prenatal Infection (poly I:C) Rat Model Ashleigh L. Osborne, Nadia Solowij, Ilijana Babic, Xu-Feng Huang and Katrina Weston-Green Neuropsychopharmacology, 2017, 42, 1447–1457 0893-133X/17 www.neuropsychopharmacology.org doi:10.1038/npp.2017.40 Neuropsychiatric disorders such as schizophrenia are associated with cognitive impairment, including learning, memory and attention deficits. Antipsychotic drugs are limited in their efficacy to improve cognition; therefore, new therapeutic agents are required. Cannabidiol (CBD), the non-intoxicating component of cannabis, has anti-inflammatory, neuroprotective and antipsychotic-like properties; however, its ability to improve the cognitive deficits of schizophrenia remains unclear. Using a prenatal infection model, we examined the effect of chronic CBD [...]

Purified Cannabidiol, the main non-psychotropic component of Cannabis sativa, alone, counteracts neuronal apoptosis in experimental multiple sclerosis, S. GIACOPPO, 2015

Purified Cannabidiol, the main non-psychotropic component of Cannabis sativa, alone, counteracts neuronal apoptosis in experimental multiple sclerosis S. GIACOPPO, T. SOUNDARA RAJAN, M. GALUPPO, F. POLLASTRO, G. GRASSI, P. BRAMANTI, E. MAZZON European Review for Medical and Pharmacological Sciences, 2015, 19, 4906-4919. Abstract. – OBJECTIVE : Multiple Sclerosis (MS) is a global concern disease leading to a progressive, chronic and demyelinating condition, affecting the central nervous system (CNS). The pathology has an inflammatory/autoimmune origin; nevertheless, neuronal cell death mechanisms are not to be underestimated. The present study was designed to test the effects of intraperitoneal administration of cannabidiol (CBD), the main non-psychotropic cannabinoid of [...]

Therapeutic Potential of Cannabinoids in Psychosis, Leweke F.M. et al., 2016

Therapeutic Potential of Cannabinoids in Psychosis. Leweke F.M., Mueller J.K., Lange B., Rohleder C. Biological Psychiatry, 2016, 79, (7) 604-612. doi: 10.1016/j.biopsych.2015.11.018.   Abstract Over recent years, the interest in the endocannabinoid system (ECS) as a new target for the treatment of schizophrenia has evolved. The ECS represents one of the most relevant neurotransmitter systems in the brain and mainly fulfills a homeostatic role in terms of neurotransmission but also with respect to inflammatory processes. Two main approaches to the modulation of endocannabinoid functioning have been chosen so far. First, the selective blockade or inverse agonism of the type 1 cannabinoid receptor has been tested for [...]

Despite their devastating social, health, and economic impact, to date no pharmacological treatment has been approved for the clinical management of cannabis dependence. Cannabidiol (CBD), one of the main compounds—together with Δ9-THC—present in the plant Cannabis sativa, has been reported to possess anxiolytic, antidepressant, and antipsychotic-like effects and neuroprotective properties. And, contrary to Δ9-THC, CBD does not appear to have addictive properties. Taken [...]
