Consultation Prep
Turn the card into questions before consultation
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.
