Latest researches are raising the hypothesis of a link between the onset of the main behavioral symptoms of ASD and the chronic neuroinflammatory condition of the autistic brain; increasing evidence of this connection is shedding light on new possible players in the pathogenesis of ASD. The endocannabinoid system (ECS) has a key role in neurodevelopment as well as in normal inflammatory responses and it is not surprising that many preclinical and clinical studies account for alterations of the endocannabinoid signaling in ASD....

Abstract Clinical and preclinical findings have suggested a role of the endocannabinoid system (ECS) in the etiopathology of autism spectrum disorder (ASD). Previous mouse studies have investigated the role of ECS in several behavioral domains; however, none of them has performed an extensive assessment of social and communication behaviors, that is, the main core features of ASD. This study employed a mouse line lacking the primary endocannabinoid receptor (CB1r) and characterized ultrasonic communication and social interaction in CB1−/−, CB1+/−, and CB1+/+ males and females. Quantitative and qualitative alterations in ultrasonic vocalizations (USVs) were observed in CB1...

Abstract Introduction: Autism Spectrum Disorder is characterized by persistent deficits in social communication, social interaction, and restricted and repetitive patterns of behavior. Some studies have shown that substances derived from Cannabis sativa improve the quality of life of autistic children without causing serious adverse effects, thus providing a therapeutic alternative. Method: This was a randomized, double-blind, placebo-controlled clinical trial to evaluate the efficacy and safety of a cannabis extract rich in cannabidiol (CBD) in autistic children. Sixty children, aged between 5 and 11 years, were selected and divided into two groups: the treatment group, which received the CBD-rich cannabis extract, and the control group, which received...

ABSTRACT Cannabis use in the United States is increasing, with highest consumption among men attheir peak reproductive years. We previously demonstrated widespread changes in spermDNA methylation with cannabis exposure in humans and rats, including genes important inneurodevelopment. Here, we use anin vitrohuman spermatogenesis model to recapitulatechronic cannabis use and assess DNA methylation at imprinted and autism spectrum dis-order (ASD) candidate genes in spermatogonial stem cell (SSC)- and spermatid-like cells.Methylation at maternally imprinted genesSGCEandGRB10was significantly altered in SSC-and spermatid-like cells, respectively, whilePEG3was significantly differentially methylatedin spermatid-like cells. Two of ten randomly selected ASD candidate genes,HCN1andNR4A2,had significantly altered methylation with cannabis exposure in SSC-like cells. Theseresults...

Abstract: Introduction: Cannabis-based medicinal products (CBMPs) have been identified as a promising novel therapeutic for symptoms and comorbidities related to autism spectrum disorder (ASD). However, there is a paucity of clinical evidence of their efficacy and safety. Objective: This case series aims to assess changes to health-related quality of life and the incidence of adverse events in patients treated with CBMPs for associated symptoms of ASD enrolled on the UK Medical Cannabis Registry (UKMCR). Methods: Patients treated with CBMPs for ASD-related symptoms for a minimum of 1 month were identified from the UKMCR. Primary outcomes were changes in validated patient-reported outcome measures [Generalised Anxiety...

Abstract Objective: The objective of this study was to evaluate the safety and efficacy of medications commonly used in autism spectrum disorder (ASD) and compare this to what current research has shown regarding medical cannabis use in this population. Methods: Searches were performed to collect information surrounding currently used medications and their safety and efficacy profiles, biologic plausibility of cannabis use for symptoms of ASD, and studies detailing cannabis' safety and efficacy profile for use in the ASD population. Results were used to compare medications to cannabis as a proposed treatment. Results: The heterogeneity of ASD produces great difficulties...

Abstract This case study aims to demonstrate the use of cannabidiol (CBD) with low-dose tetrahydrocannabinol (THC) in managing symptoms associated with autism spectrum disorder (ASD) to increase the overall quality of life for these individuals and their families. ASD is a neurodevelopmental disorder affecting cognitive development, behavior, social communication, and motor skills. Despite the increasing awareness of ASD, there is still a lack of safe and effective treatment options. The study includes a nine-year-old male patient who was diagnosed with nonverbal ASD. He exhibited emotional outbursts, inappropriate behaviors, and social deficits including challenges in communicating his needs with others. Since the patient was unable...

Please use this link to access publication Abstract Background Autism spectrum disorder is specifically approved for medical cannabis consumption in 20 U.S. states, the District of Columbia, and the Territory of Puerto Rico. Despite increased access, there is limited knowledge about who consumes medical cannabis, what they consume, and perceived effectiveness. We addressed these gaps by conducting a natural history study of medical cannabis consumption. Method Children and their families engaged with a large pediatric care system were recruited to complete a telephonic study regarding their medical cannabis consumption. All children had to be consuming approved medical cannabis products issued from a state that had legalized medical cannabis for the treatment of ASD or related behaviors (irritability, hyperactivity, anxiety)...

Abstract:  Background: Autistic Spectrum Disorder (ASD) is a common neurodevelopmental disorder and no effective treatment for the core symptoms is currently available. The present study is part of a larger clinical trial assessing the effects of cannabis oil on autism co-morbidities. Objectives: The aim of the present study was to assess the safety of a CBD-rich oil treatment in children and adolescents with ASD. Methods: Data from 59 children and young adults (ages 5–25 years) from a single-arm, ongoing, prospective, open-label, one center, phase III study was analyzed. Participants received the Nitzan Spectrum® Oil, with cannabis extracts infused in medium chain triglyceride (MCT) oil with a cannabidiol:THC...

Abstract In recent years there has been growing interest in the potential benefits of CBD-rich cannabis treatment for children with ASD. Several open label studies and one double-blind placebo-controlled study have reported that CBD-rich cannabis is safe and potentially effective in reducing disruptive behaviors and improving social communication. However, previous studies have mostly based their conclusions on parental reports without the use of standardized clinical assessments. Here, we conducted an open label study to examine the efficacy of 6 months of CBD-rich cannabis treatment in children and adolescents with ASD. Longitudinal changes in social communication abilities and restricted and repetitive behaviors (RRB) were quantified...
