What This Study Found

CBD efficacy for treating seizures has been confirmed by RCTs for LGS, Dravet syndrome, and TSC. Side effects are frequent but mostly mild to moderate and transient. There is no global consensus on regulatory approval, but CBD is considered promising with a good safety profile.

Key Numbers

69 articles reviewed; efficacy confirmed for LGS, Dravet, TSC; side effects mostly mild-moderate and transient

How They Did This

Critical literature review of 69 articles from PubMed, Cochrane, and SciELO databases, without date, language, or study design restrictions, covering CBD for refractory epilepsy in pediatric populations.

Why This Research Matters

For families of children with treatment-resistant epilepsy, knowing that CBD has been confirmed effective through rigorous clinical trials provides evidence-based guidance in a landscape full of unproven claims.

The Bigger Picture

While CBD has become the most successful cannabinoid medicine to date, regulatory approaches vary globally. The evidence base continues to support expanding access for children with these specific epilepsy syndromes.

What This Study Doesn't Tell Us

Review focused on published literature which may have publication bias. Long-term safety data in pediatric populations remain limited.

Questions This Raises

  • ?Could CBD be effective for other childhood epilepsy syndromes beyond the three approved indications?
  • ?What are the long-term neurodevelopmental effects of chronic CBD use in children?
