Target: All ADHD (80 authors, 27 countries, 366 endorsers) Type: InternationalConsensusStatement Grade: A

3-Line Summary

What: The World Federation of ADHD (WFADHD) selected only large-scale studies (2,000+ participants) or meta-analyses of 5+ studies to derive 208 evidence-based conclusions about ADHD.
Who: All individuals and caregivers who need scientific consensus on the nature, course, causes, and treatment of ADHD.
Result: This consensus statement confirmed ADHD as a real neurodevelopmental disorder related to brain developmental processes. Twin and adoption studies indicate a substantial genetic contribution at the population level (estimated ~74%), and neuroimaging studies have observed group-level structural and functional differences. However, this figure is a population-level statistical estimate, not a predictor of individual diagnosis.
