Cannabis for refractory epilepsy in children : a review focusing on CDKL5 Deficiency Disorder, Tristan Dale et al., 2019

Cannabis for refractory epilepsy in children : a review focusing on CDKL5 Deficiency Disorder Tristan Dale, Jenny Downs, Heather Olson, Ann Marie Bergin, Stephanie Smith and Helen Leonard Epilepsy Research, 2019 DOI: https://doi.org/doi:10.1016/j.eplepsyres.2019.02.001   Abstract Severe paediatric epilepsies such as CDKL5 Deficiency Disorder (CDD) are extremely debilitating, largely due to the early-onset and refractory nature of the seizures. Existing treatment options are often ineffective and associated with a host of adverse effects, causing those that are affected to seek alternative treatments. Cannabis based products have attracted significant attention over recent years, primarily driven by reports of miraculous cures and a renewed public preference for ‘natural’ therapies, [...]

Medical Cannabis and Cannabinoids : An Option for the Treatment of Inflammatory Bowel Disease and Cancer of the Colon?, Magdalena Grill et al., 2018

Medical Cannabis and Cannabinoids : An Option for the Treatment of Inflammatory Bowel Disease and Cancer of the Colon? Magdalena Grill, Carina Hasenoehrl, Martin Storr, Rudolf Schicho Medical Cannabis and Cannabinoids, 2018, 1, 28–35 © 2018 The Author(s) Published by S. Karger AG, Basel E-Mail karger@karger.com www.karger.com/mca DOI: 10.1159/000489036   Abstract : In the past few years, we have witnessed a surge of new reports dealing with the role of cannabinoids, synthetic as well as herbal, in the mechanisms of inflammation and carcinogenesis. However, despite the wealth of in vitro data and anecdotal reports, evidence that cannabinoids could act as beneficial drugs in inflammatory bowel disease (IBD) or in [...]

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 [...]

Cannabinoid Delivery Systems for Pain and Inflammation Treatment, Natascia Bruni et al., 2018

Cannabinoid Delivery Systems for Pain and Inflammation Treatment Natascia Bruni, Carlo Della Pepa, Simonetta Oliaro-Bosso, Enrica Pessione, Daniela Gastaldi and Franco Dosio Molecules, 2018, 23, 2478 doi:10.3390/molecules23102478        www.mdpi.com/journal/molecules Abstract : There is a growing body of evidence to suggest that cannabinoids are beneficial for a range of clinical conditions, including pain, inflammation, epilepsy, sleep disorders, the symptoms of multiple sclerosis, anorexia, schizophrenia and other conditions. The transformation of cannabinoids from herbal preparations into highly regulated prescription drugs is therefore progressing rapidly. The development of such drugs requires well-controlled clinical trials to be carried out in order to objectively establish therapeutic efficacy, dose ranges 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. [...]
