ABSTRACT
This large classification describes disorders that usually begin or become evident in infancy, childhood, or adolescence. Any clinician using this category in children or adolescents should have a basic knowledge of child development in order to be able to distinguish true clinical syndromes from normal variations for age or developmental stage.https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781315820774/fad306a6-9f2f-469b-a373-bfcdd1211b15/content/ifig0031_B.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/>
