“Autism Spectrum Disorder (ASD) lacks an established pharmacological treatment protocol, prompting interest in alternative therapeutic approaches, such as cannabidiol (CBD). This systematic review evaluates the potential efficacy and safety of CBD-rich formulations in managing ASD symptoms. A comprehensive search of PubMed, Embase, Scopus, Web of Science, and the Cochrane Library identified seven studies encompassing 494 patients from Brazil and Israel.
Preliminary findings suggest that CBD-rich formulations may provide modest benefits for sleep and social interaction, with a reduction in anxiety symptoms. Regarding core ASD symptoms and behavioral outcomes, cannabinoids demonstrated greater efficacy compared to placebo in some studies. However, adverse events varied, and response to treatment was inconsistent across individuals. While cannabinoids, particularly CBD-rich formulations, appear to be relatively safe and potentially beneficial, further large-scale, controlled trials comparing CBD to established ASD treatments are essential to clarify its role and long-term impact in ASD management.”
