ABSTRACT
There is great progress in the study of the diagnosis of hyperkinetic disorders in China within the latest ten years, but it is not enough. Three features are referred by reanalyzing 281 articles dating from 1997 to 2004 collected by the CJFD: 1) Several editions of diagnostic criteria and diagnostic methods are simultaneously used; 2) Comparing with the rate of utilization of the new edition, the old editions of diagnostic criteria constitute a small percentage ; 3) Diagnostic criteria and diagnostic tools have some shortcomings. Four recommendations maybe help to solve these problems:1) Make parents and teachers advance their acknowledgement of hyperkinetic disorders; 2) Develop and improve the diagnostic criteria and diagnostic tools through more researches; 3) Use advanced scientific apparatuses more widely; 4) Establish a perfect diagnostic system according to our culture.
