Cannabidiol as a pharmacological intervention in attention deficit hyperactivity disorder (ADHD): a narrative review
Abstract
Introduction: attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by inattention, impulsivity, and hyperactivity, impacting social and academic performance. Conventional treatment includes stimulant and non-stimulant medications, along with cognitive-behavioral therapy, but side effects may limit adherence. Objective: to review the literature on the use of cannabidiol (CBD) in the treatment of ADHD. Methods: a narrative literature review through searches in scientific databases, including experimental and clinical studies evaluating the effects of CBD in animal models and human subjects. Results: animal studies demonstrated reduced hyperactivity and improved social behavior, without significant changes in attention. In a clinical trial with adults, CBD treatment improved impulsivity and showed a trend toward better attention. Conclusion: although findings are promising, further controlled clinical studies are needed to confirm the efficacy and safety of cannabidiol in ADHD management.
