This retrospective study assessed tolerability and efficacy of cannabidiol-rich cannabis, in 60 children with ASD and severe behavioral problems (age = 11.8 +/- 3.5, range 5.0-17.5; 77% low functioning; 83% boys). Efficacy was assessed using the Caregiver Global Impression of Change scale. Adverse events included sleep disturbances (14%) irritability (9%) and loss of appetite (9%). One girl who used higher tetrahydrocannabinol had a transient serious psychotic event which required treatment with an antipsychotic. Following the cannabis treatment, behavioral outbreaks were much improved or very much improved in 61% of patients. This preliminary study supports feasibility of CBD-based cannabis trials in children with ASD.

Cannabinoid treatment for autism: a proof-of-concept randomized trial / Adi ARAN in Molecular Autism, 12 (2021)  

Public ISBD [article]  inMolecular Autism > 12 (2021) . - 6p. Titre : Cannabinoid treatment for autism: a proof-of-concept randomized trial Type de document : texte imprimé Auteurs : Adi ARAN, Auteur ; Moria HAREL, Auteur ; Hanoch CASSUTO, Auteur ; Lola POLYANSKY, Auteur ; Aviad SCHNAPP, Auteur ; Nadia WATTAD, Auteur ; Dorit SHMUELI, Auteur ; Daphna GOLAN, Auteur ; Francisco Xavier CASTELLANOS, Auteur Article en page(s) : 6p. Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Behavior  Cannabidiol  Cannabinoids  Child psychiatry  Clinical trials randomized controlled  Developmental disorders  Entourage effect  Neuropsychology  Tetrahydrocannabinol Index. décimale : PER Périodiques Résumé : BACKGROUND: Endocannabinoid dysfunction in animal models of autism spectrum disorder (ASD) and accumulating, albeit anecdotal, evidence for efficacy in humans motivated this placebo-controlled double-blind comparison of two oral cannabinoid solutions in 150 participants (age 5-21 years) with ASD. METHODS: We tested (1) BOL-DP-O-01-W, a whole-plant cannabis extract containing cannabidiol and Δ9-tetrahydrocannabinol at a 20:1 ratio and (2) BOL-DP-O-01, purified cannabidiol and Δ9-tetrahydrocannabinol at the same ratio. Participants (N = 150) received either placebo or cannabinoids for 12-weeks (testing efficacy) followed by a 4-week washout and predetermined cross-over for another 12 weeks to further assess tolerability. Registered primary efficacy outcome measures were improvement in behavioral problems (differences between whole-plant extract and placebo) on the Home Situation Questionnaire-ASD (HSQ-ASD) and the Clinical Global Impression-Improvement scale with disruptive behavior anchor points (CGI-I). Secondary measures were Social Responsiveness Scale (SRS-2) and Autism Parenting Stress Index (APSI). RESULTS: Changes in Total Scores of HSQ-ASD (primary-outcome) and APSI (secondary-outcome) did not differ among groups. Disruptive behavior on the CGI-I (co-primary outcome) was either much or very much improved in 49% on whole-plant extract (n = 45) versus 21% on placebo (n = 47; p = 0.005). Median SRS Total Score (secondary-outcome) improved by 14.9 on whole-plant extract (n = 34) versus 3.6 points after placebo (n = 36); p = 0.009). There were no treatment-related serious adverse events. Common adverse events included somnolence and decreased appetite, reported for 28% and 25% on whole-plant extract, respectively (n = 95); 23% and 21% on pure-cannabinoids (n = 93), and 8% and 15% on placebo (n = 94). Limitations Lack of pharmacokinetic data and a wide range of ages and functional levels among participants warrant caution when interpreting the results. CONCLUSIONS: This interventional study provides evidence that BOL-DP-O-01-W and BOL-DP-O-01, administrated for 3 months, are well tolerated. Evidence for efficacy of these interventions are mixed and insufficient. Further testing of cannabinoids in ASD is recommended. Trial registration ClinicalTrials.gov: NCT02956226.

Cognitive Abilities and Irritability Are the Main Factors Influencing Initial Placement of Autistic Preschoolers in Special or Mainstream Education in Israel / Moran BACHRACH in Autism Research, 19-3 (March 2026)

These settings differ in their staff composition and expertise, ability to implement structured autism interventions, ability to integrate autistic and typically developing children, and costs. Here, we examined whether there were significant differences in the behavioral abilities and developmental difficulties of children placed in special versus mainstream public education in Israel, where there is a systematic dichotomy between the two educational settings. We analyzed data from 165 autistic children, 120 in special and 45 in mainstream education, who completed comprehensive behavioral assessments at a mean age of 37.8?months, as they entered their first preschool setting. Children placed in special education exhibited significantly poorer cognitive abilities and higher irritability and hyperactivity than children in mainstream education while there were no significant differences in autism severity or adaptive behaviors across groups. Moreover, cognitive and irritability scores were sufficient for classifying children across the two settings with an average accuracy of 76.4% when using a pruned decision tree algorithm and a 5-fold cross-validation procedure. These findings extend previous research by demonstrating that cognitive abilities and irritability are the strongest predictors of preschool educational placement. Further longitudinal research is needed to determine whether these placement decisions benefit the children as they develop.

How Adolescents with Autism Spectrum Disorder (ASD) Spontaneously Attend to Real-World Scenes: Use of a Change Blindness Paradigm / Michal HOCHHAUSER in Journal of Autism and Developmental Disorders, 48-2 (February 2018)

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 detail of the scene. Change detection response times were measured and compared between groups. Marginal details were more difficult to detect than central details of the scenes in both groups, however, the response times of the ASD group were lower than the TD group. These results challenge the hypothesis of superior visual detection in ASD.

Investigating attention in young adults with autism spectrum disorder (ASD) using change blindness and eye tracking / Michal HOCHHAUSER in Research in Autism Spectrum Disorders, 84 (June 2021)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 84 (June 2021) . - 101771 Titre : Investigating attention in young adults with autism spectrum disorder (ASD) using change blindness and eye tracking Type de document : texte imprimé Auteurs : Michal HOCHHAUSER, Auteur ; Adi ARAN, Auteur ; Ouriel GRYNSZPAN, Auteur Article en page(s) : 101771 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Change blindness  Eye tracking  Social interaction  Young adults Index. décimale : PER Périodiques Résumé : Background Social interaction at its core entails allocating attention to relevant stimuli. As such, the perception of change requires attention, but studies have suggested that the social impairment in people with autism spectrum disorder (ASD) occurs at the attentual level of "on-line" social cognition. Method Forty-four young adults—22 with autism spectrum disorder (ASD) and 22 with typical development (TD)—participated in two experiments. The first used a change blindness (CB) paradigm where attention was investigated through the detection of changed items with central and marginal levels of interest when viewing images of everyday scenarios. Eye-tracking was used to compare response times, first fixations and total fixation time on changes. The second used social films with eye tracking of gaze fixations. Results Participants with ASD were slower in response time and first fixation than were participants with TD. Participants with TD showed longer fixation on items with marginal (compared to central) levels of interest. The social-film experiment showed that participants with ASD were slower to orient their gazes towards the characters’ faces and looked at speaking characters for less time than did the group with TD. This result correlates with less use of mental verbs in their narratives and less time spent looking at marginal items in the CB experiment. Conclusions Results suggest reduced processing speed in young adults with ASD, which is associated with enhanced processing of local details. Clinically, these results imply that teaching strategies (e.g., cognitive cues) to process social context efficiently could benefit individuals with ASD.
