There is a perception in the community that too many children are diagnosed with attention-deficit hyperactivity disorder (ADHD) and treated with medication. Conversely, some experts believe the disorder could be underdiagnosed and that efforts should be made to improve diagnostic reliability.^1,2 Findings of studies in different countries have shown that many children who meet diagnostic criteria for ADHD—including impairment criteria—never receive a clinical diagnosis.^3,4 Rates of diagnosis vary considerably both between and within countries, with many variables affecting the likelihood of diagnosis.

学校在多动症诊断中的作用

社区中有一种观念，即有太多儿童被诊断出患有注意力缺陷多动障碍（ADHD）并接受药物治疗。相反，一些专家认为该疾病可能未得到充分诊断，因此应努力提高诊断的可靠性。^1,2不同国家的研究结果表明，许多符合ADHD诊断标准（包括障碍标准）的儿童从未接受过临床诊断。^3,4国家之间和国家内部的诊断率差异很大，许多变量会影响诊断的可能性。
