Tel Aviv, Israel: The administration of CBD-rich oil extracts in children with autism is associated with reduced impulsivity and improvements in other ADHD-related symptoms, according to data published in the journal Current Neuropharmacology.
Israeli researchers assessed the efficacy of CBD-dominant extracts in a cohort of children diagnosed with ASD (autism spectrum disorder) and ADHD (attention deficit hyperactivity disorder) over three-to-six months. Study participants were assessed at baseline and at the completion of the study by their schoolteachers utilizing a standardized rating scale (the Conners’ Teaching Rating Scale questionnaire).
Assessments revealed “significant improvements … in the following categories: anxious-shyness, perfectionism, ADHD index, emotional liability, and hyperactive-impulsivity.” Participants also demonstrated reduced hyperactivity and improvements in their ability to maintain attention, though these changes did not reach statistical significance.
The study’s authors concluded: “This is the first prospective study to evaluate the effects of CBD-rich cannabis on ADHD symptoms in children with ASD using standardized teacher-based Assessments (CTRS). The findings indicate improvements in core behavioral domains. While previous studies have focused primarily on parent-reported outcomes or small-scale trials, our results support emerging evidence on the role of cannabinoids in modulating attention and emotional regulation. … These findings support the need for future clinical trials to validate efficacy and determine optimal dosing.”
Placebo-controlled clinical trials have previously demonstrated that CBD-rich cannabis extracts are safe and effective in mitigating symptoms in children with ASD, while observational studies indicate that cannabis inhalation reduces ASD symptoms in adults.
