CBD Gel Promising for Fragile X Syndrome Megan Brooks Medscape, 2019 https://www.medscape.com/viewarticle/913267?nlid=129947_2052&src=WNL_mdplsnews_190524_mscpedit_psyc&uac=292598PZ&spon=12&impID=1974025&faf=1 SAN FRANSICO — A clear transdermal cannabidiol (CBD) gel (ZYN002, Zynerba Pharmaceuticals) improved emotional and behavioral symptoms experienced by children and adolescents with fragile X syndrome in a phase 2 open-label study, the company reports. ZYN002 met its primary endpoint, with patients demonstrating a 46% improvement in the total score on the Anxiety, Depression, and Mood Scale (ADAMS) at week 12 compared to baseline. ZYN002 also led to meaningful improvements in all measures of the Aberrant Behavior Checklist for Fragile X (ABC-FXS), which addresses the key symptoms of fragile X syndrome, including social avoidance, [...]

Medical Cannabis for Adult Attention Deficit Hyperactivity Disorder: Sociological Patient Case Report of Cannabinoid Therapeutics in Finland, Aleksi Mikael Markunpoika Hupli, 2018

Medical Cannabis for Adult Attention Deficit Hyperactivity Disorder: Sociological Patient Case Report of Cannabinoid Therapeutics in Finland Aleksi Mikael Markunpoika Hupli Medical Cannabis and Cannabinoids, 2018, 1, 112–118 DOI: 10.1159/000495307 https://www.karger.com/Article/FullText/495307 Abstract : This paper presents a detailed patient case report of a male patient who was diagnosed in adulthood (aged 33) with attention deficit hyperactivity disorder (ADHD) and treated initially with immediate-release methylphenidate (Ritalin® 10 mg twice daily). After experiencing adverse effects from prolonged use of this medication and afterwards other medications that were prescribed as alternatives, the patient discovered that cannabinoid therapeutics (CT) had been experimented inside the EU area to treat patients with [...]

Individual and combined effects of acute delta-9-tetrahydrocannabinol and cannabidiol on psychotomimetic symptoms and memory function, Celia J. A. Morgan et al., 2018

Individual and combined effects of acute delta-9-tetrahydrocannabinol and cannabidiol on psychotomimetic symptoms and memory function Celia J. A. Morgan, Tom P. Freeman, Chandni Hindocha, Grainne Schafer, Chelsea Gardner and H. Valerie Curran Translational Psychiatry, 2018, 8, 181 DOI 10.1038/s41398-018-0191-x https://www.researchgate.net/publication/264860201   Abstract The main active ingredient in cannabis, delta-9-tetrahydrocannabinol (THC), can acutely induce psychotic symptoms and impair episodic and working memory. Another major constituent, cannabidiol (CBD), may attenuate these effects. This study aimed to determine the effects of THC and CBD, both alone and in combination on psychotic symptoms and memory function. A randomised, double-blind crossover design compared the effects of (i) placebo, (ii) THC 8mg, (iii) CBD [...]

Cannabis Therapeutics and the Future of Neurology, Ethan B. Russo, 2018

Cannabis Therapeutics and the Future of Neurology Ethan B. RUSSO Frontiers in Integrative Neuroscience, 18 October 2018 https://doi.org/10.3389/fnint.2018.00051 Abstract : Neurological therapeutics have been hampered by its inability to advance beyond symptomatic treatment of neurodegenerative disorders into the realm of actual palliation, arrest or reversal of the attendant pathological processes. While cannabis-based medicines have demonstrated safety, efficacy and consistency sufficient for regulatory approval in spasticity in multiple sclerosis (MS), and in Dravet and Lennox-Gastaut Syndromes (LGS), many therapeutic challenges remain. This review will examine the intriguing promise that recent discoveries regarding cannabis-based medicines offer to neurological therapeutics by incorporating the neutral phytocannabinoids tetrahydrocannabinol (THC), cannabidiol [...]

Cannabinoid CB2 Receptor Gene and Environmental Interaction in the Development of Psychiatric Disorders, Hiroki Ishiguro et al., 2018

Cannabinoid CB2 Receptor Gene and Environmental Interaction in the Development of Psychiatric Disorders Hiroki Ishiguro, Yasue Horiuch, Koichi Tabata, Qing-Rong Liu, Tadao Arinami and Emmanuel S. Onaivi Molecules, 2018, 23, 1836; doi : 10.3390/molecules23081836 Abstract : CB2 cannabinoid receptor (CB2R) gene is associated with depression. We investigated the gene-environment interaction between CB2R function and diverse stressors. First, anxiety-like behavior during chronic-mild-stress (CMS) was evaluated in C57BL/6JJmsSlc mice following treatment with CB2R agonist JWH015 or inverse-agonist AM630. Second, locomotor activity and anxiety-like behavior were measured following exposure to an immune poly I:C stressor. Gene expressions of HPA axis related molecules, Fkbp5, Nr3c1 and Crf and [...]

Chronic Adolescent D9-Tetrahydrocannabinol Treatment of Male Mice Leads to Long-Term Cognitive and Behavioral Dysfunction, Which Are Prevented by Concurrent Cannabidiol Treatment, Michelle Murphy et al., 2017

Chronic Adolescent D9-Tetrahydrocannabinol Treatment of Male Mice Leads to Long-Term Cognitive and Behavioral Dysfunction, Which Are Prevented by Concurrent Cannabidiol Treatment Michelle Murphy,Sierra Mills, Joanna Winstone, Emma Leishman, Jim Wager-Miller, Heather Bradshaw, and Ken Mackie Cannabis and Cannabinoid Research, Volume 2.1, 2017 DOI: 10.1089/can.2017.0034 Abstract Introduction : The high prevalence of adolescent cannabis use, the association between this use and later psychiatric disease, and increased access to high-potency cannabis highlight the need for a better understanding of the long-term effects of adolescent cannabis use on cognitive and behavioral outcomes. Furthermore, increasing Δ9-tetrahydrocannabinol (THC) in high-potency cannabis is accompanied by a decrease in cannabidiol (CBD), thus [...]

Chapter : The endocannabinoid system in Fragile X Syndrome, Henry G. S. Martin et al., 2017

Chapter : The endocannabinoid system in Fragile X Syndrome Henry G. S. Martin, Daniela Neuhofer and Olivier J.J. Manzoni Fragile X Syndrome : From Genetics to Targeted Treatment, 2017, Pages 241-259 DOI: 10.1016/B978-0-12-804461-2.00012-3 Addresses: INSERM U901, INMED and UMR S901, Aix-Marseille University Marseille 13009, France. Abstract : Endocannabinoid signaling is a finely tuned system of molecules and lipid messengers that modulate neurotransmission in a rapid and sustained manner at many central synapses. The endocannabinoid system is important for many brain activities, but is also implicated in several neuropsychiatric disorders. In this chapter we discuss emerging evidence of dysfunction in endocannabinoid signaling in Fragile X Syndrome from the Fmr1 knockout mouse model. [...]

Cannabinoid Actions on Neural Stem Cells : Implications for Pathophysiology, Rui S. Rodrigues et al., 2019

Cannabinoid Actions on Neural Stem Cells : Implications for Pathophysiology Rui S. Rodrigues, Diogo M. Lourenço, Sara L. Paulo, Joana M. Mateus, Miguel F. Ferreira, Francisco M. Mouro, João B. Moreira, Filipa F. Ribeiro, Ana M. Sebastião and Sara Xapelli Molecules, 2019, 24, 1350, 59 pp. Abstract : With the increase of life expectancy, neurodegenerative disorders are becoming not only a health but also a social burden worldwide. However, due to the multitude of pathophysiological disease states, current treatments fail to meet the desired outcomes. Therefore, there is a need for new therapeutic strategies focusing on more integrated, personalized and effective approaches. The prospect [...]

Modulation of Astrocyte Activity by Cannabidiol, a Nonpsychoactive Cannabinoid, Ewa Kozela et al., 2017

Modulation of Astrocyte Activity by Cannabidiol, a Nonpsychoactive Cannabinoid. Ewa Kozela, Ana Juknat, and Zvi Vogel International Journal of Molecular Sciences, 2017, 18, 1669, 20 pp. doi:10.3390/ijms18081669 PMID : 28788104   PMCID : PMC5578059 Abstract The astrocytes have gained in recent decades an enormous interest as a potential target for neurotherapies, due to their essential and pleiotropic roles in brain physiology and pathology. Their precise regulation is still far from understood, although several candidate molecules/systems arise as promising targets for astrocyte-mediated neuroregulation and/or neuroprotection. The cannabinoid system and its ligands have been shown to interact and affect activities of astrocytes. Cannabidiol (CBD) is the main [...]
