The ADHD Overdiagnosis Debate — What a 334-Study Review Reveals

3-Line Summary

1. What: A systematic scoping review that organized evidence on ADHD overdiagnosis through five frameworks.
2. Who: Parents and caregivers wondering, "Are too many children being diagnosed with ADHD these days?"
3. Result: Increases in diagnosis rates (45 studies), additional diagnoses in mild cases (25 studies), and increasing medication use (83 studies) were identified. However, this review does not conclude that "overdiagnosis is fact" — rather, it organizes the current state and context of evidence suggesting the possibility.

Action Tips

• If you have doubts about your child's diagnosis, you can ask the specialist, "What criteria and procedures were used for the evaluation?" This is not questioning the diagnosis — it is a natural step in understanding the process.
• When feeling anxious about "overdiagnosis," remember that this review discusses the context of diagnostic processes, not that your child's diagnosis is wrong.
• You can ask whether the evaluation combined information from multiple settings (home, school).
