【目的】探讨注意缺陷多动障碍(attention deficit hyperactivity disorder,ADHD)与抽动障碍(tic disorder,TD)共病(comorbid attention deficit hyperactivity disorder and tic disorder,CAT)患儿智力特征。【方法】采用韦氏儿童智力量表(China-Wechsler Intelligence Scale for Children,C-WISC)对CAT组60例、ADHD组79例、TD组60例及正常对照组71名儿童进行智力测验,分别计算各分测验的量表分、言语智商(verbal intelligence quotient,VIQ)、操作智商(per-formance intelligence quotient,PIQ)和总智商(full intelligence quotient,FIQ),进行对比分析。【结果】 CAT组与ADHD组比较,10项分测验及VIQ、PIQ、FIQ两组比较差异均无统计学意义(P>0.05);CAT组与TD组比较,言语测验中的算术分测验,操作测验中的译码分测验低于TD组(P<0.01),而操作测验中的填图分测验高于TD组(P<0.05);与正常对照组相比,CAT组儿童言语测验中的算术分测验得分低于对照组(P<0.05),言语测验中的领悟分测验及操作测验中的译码分测验得分低于对照组(P<0.01)。【结论】 CAT患儿总智商在正常范围,但存在智力结构发展不均衡的状况,ADHD可能是影响认知功能的主要原因。
【Objective】 To investigate the mental characteristics of children with attention deficit hyperactivity disorder (ADHD) and tic disorder (tic disorder, TD). 【Methods】 Sixty-six patients in CAT group, 79 in ADHD group, 60 in TD group and 71 in normal control group were subjected to intelligence test using China-Wechsler Intelligence Scale for Children (C-WISC) The scores of verbal intelligence quotient, verbal intelligence quotient (VIQ), per-formance intelligence quotient (PIQ) and total intelligence quotient (FIQ) were calculated for comparative analysis. 【Results】 There was no significant difference between CAT group and ADHD group in 10 sub-tests and VIQ, PIQ and FIQ (P> 0.05) The decoding sub-test in the operation test was lower than that in the TD group (P <0.01), while the operation test in the test sub-test was higher than that in the TD group (P <0.05). Compared with the normal control group, (P <0.05). The scores of comprehension subtest and operation subtest in verbal test were lower than those of the control group (P <0.01). 【Conclusion】 The total IQ of CAT children is in the normal range, but there is an unbalanced development of mental structure. ADHD may be the main reason that affects cognitive function.
