慢性抽动障碍儿童持续性注意力的对照研究

Study on sustained attention in children with chronic tic disorders

【目的】探索伴与不伴注意缺陷多动障碍(attention deficit hyperactivity disorder,ADHD)的慢性抽动障碍(chronic tic disorders,CTD)儿童持续性注意力的特征。【方法】对伴与不伴ADHD的CTD儿童和正常对照儿童采用视听整合持续操作测验(integrated visual and auditory continuous performance test,IVA-CPT)进行对比分析。【结果】三组间综合控制商数、听觉和视觉控制商数、综合注意商数、听觉注意商数、视觉和听觉的谨慎商数、一致性商数及注意集中商数、听觉警醒商数和听觉速度商数的差异有显著性(P<0.05)。不伴ADHD的CTD组和对照组、不伴ADHD和伴ADHD的CTD组之间的差异均有显著性(P<0.05)。【结论】不伴ADHD的CTD儿童也存在反应控制力和持续性注意力的损害,伴有的ADHD加重了这种损害。

[Objective] Explore the character of sustained attention in children with chronic tie disorders （CTD）. [ Methods] CTD children with and without eomorbid attention deficit hyperactivity disorder （ADHD） as well as normal controls were assessed by integrated visual and auditory continuous performance test（ IVA CPT）. The scores between groups were compared. [Results] There were significant differences between three groups in most of the scores. The differences between CTD without ADHD group and controls, CTD with and without ADHD group were both significant（P〈0.05）. [Conclusions] The ability of response control and sustained attention of children with CTD is impaired, even without eomorbid ADHD. Comorbid ADHD is associated with more response control and attention impairment.
