摘要
目的:探讨注意缺陷多动障碍(ADHD)儿童执行功能的特征。方法:采用Stroop效应、视觉和听觉Go/No-Go反应、倒背数字、延缓期的空间位置记忆广度、伦敦塔任务和连线测验分别测试40例ADHD儿童和25例正常对照组儿童的反应抑制、语音工作记忆、视空间工作记忆、计划能力和定势转移能力。结果:1.ADHD儿童完成字义与字色相矛盾的字色命名时间较正常对照组儿童明显延长(P﹤0.05)。2.ADHD儿童完成视觉和听觉的Go/No-Go反应所犯错误数均较正常对照组儿童明显增多(P﹤0.01)。3.ADHD儿童倒背数字分数和延缓期的空间位置记忆广度均较正常对照组儿童明显低(P﹤0.01)。4.ADHD儿童完成两步、四步和五步伦敦塔任务的时间均较正常对照组儿童明显延长、犯错误数明显增多(P﹤0.05);而完成四步、五步伦敦塔任务的最初计划时间则较正常对照组儿童明显缩短(P﹤0.01)。5.ADHD儿童完成连线测验甲式的时间和犯错误数与正常对照组儿童无显著性差异(P﹥0.05),而完成乙式所需时间则较正常对照组儿童明显延长、犯错误数较正常对照组儿童明显增多(P﹤0.05)。结论:ADHD儿童存在反应抑制、语音工作记忆、视空间工作记忆、计划能力和定势转移能力等多项执行功能的缺陷。
Objectives: To study the executive function (EF) profiles in children with ADHD. Methods: 1.We used some neuropsychological tests,including Stroop test, visual and auditory Go/No-Go tasks, digits reciting inverse, delayed spacial position memory span test, tower of London (TOL), tail making test (TMT),to evaluate the capacity of response inhibition, phonological working memory, visual-spacial working memory, planning and set-shifting of subjects. Results: 1.The ADHD children spent more time to accomplish color naming when the word color was inconsistent with the word meaning than normal control (NC) in Stroop test(p﹤0.05). 2.The ADHD children made more errors than NC in both visual and auditory Go/No-Go test(p﹤0.01). 3.The scores of digits reciting inverse was lower in ADHD than NC(p﹤0.01). 4.The representation of ADHD was poorer than NC in delayed spacial position memory span test(p﹤0.01). 5. In TOL test, the ADHD children spent more time in all of two-move, four-move and five-move tasks than NC, and broke rules more frequently than NC(p﹤0.05). 6.In TMT, the ADHD children spent more time and made more errors on part B than NC(p﹤0.05), and there was no significant difference on part A (p﹥0.05). Conclusions: The obvious impaired executive functions are found in children with ADHD, involving poor response inhibition,impaired working memory, dysfunction of planning and set-shifting.
