Wiggins et al. recently used data from 3 longitudinal studies spanning preschool and early school children to form an empirically derived framework for early childhood disruptive mood dysregulation disorder (EC-DMDD), ie, a theoretical entity based on all DMDD criteria except the age at onset. The authors showed that the presence of EC-DMDD strongly predicted irritability-related syndromes at early school-ages. The most striking result is that virtually all youths with DMDD had chronic irritability in preschool years (>99%), a finding that challenges the view that DMDD cannot be diagnosed before 6 years of age. In our opinion, the developmental view on DMDD adopted by the authors is particularly welcome to address some of the nosological issues encountered with this disorder.
Wiggins 等人最近使用了来自三个纵向研究的数据，这些研究涵盖了学龄前和小学儿童，为幼儿情绪失调障碍（EC-DMDD）形成了一个经验主义的理论框架，即基于除发病年龄以外的所有 DMDD 标准的理论实体。作者表明，EC-DMDD 的存在强烈预示着学龄早期与易激惹相关的综合征。最引人注目的结果是，几乎所有患有 DMDD 的青少年在学龄前都有慢性易激惹（>99%），这一发现挑战了 DMDD 不能在 6 岁之前诊断的观点。在我们看来，作者采用的 DMDD 发展观特别有助于解决该障碍的一些分类学问题。
