Landmark finding that showed brains of kids with ADHD mature later was actually a mirage in the data, new research finds
New research has challenged a landmark study that claimed children with ADHD have delayed brain maturation. The original findings, based on a smaller sample, may have been skewed by average sex differences in brain development. This new study suggests that the earlier conclusions about ADHD brain development were misleading.
- ▪A foundational study claimed that ADHD brains mature later, but new research indicates this was a mirage.
- ▪The earlier findings may have reflected average sex differences rather than true developmental delays in ADHD children.
- ▪The new study casts doubt on previous conclusions about brain development in children with ADHD.
