The author reviews the issue on whether Rett syndrome (RS) is a subtype of pervasive developmental disorders (PDDs). More than 200 articles of RS have been published in the last 10 years. Internal and external validities of RS have been established by several independent studies. There remains the question whether RS presents clinical features that meet the total criteria for PDDs. The available data seem to support the idea of classifying RS as a subtype of PDDs in the DSM-IV.
作者回顾了关于雷特综合征（RS）是否为广泛性发育障碍（PDDs）亚型的问题。在过去十年中已发表了200多篇关于RS的文章。多项独立研究确立了RS的内部和外部效度。RS是否呈现出符合PDDs全部标准的临床特征这一问题依然存在。现有数据似乎支持在《精神疾病诊断与统计手册》第四版（DSM-IV）中将RS归类为PDDs亚型的观点。
