中文摘要：

目的：探讨视觉图形工作记忆、视觉空间工作记忆在不同亚型注意缺陷多动障碍（ADHD）儿童及对照组儿童的脑反应特征及其差异。方法：采用1：1病例对照研究，对6-12岁102例ADHD儿童[注意缺陷型（PI）59例，多动／冲动型（HI）20例，混合型（CT）23例]和102例正常对照组儿童进行视觉图形工作记忆、视觉空间工作记忆测试。结果：①ADHD儿童视觉图形工作记忆、视觉空间工作记忆各项指标均显著低于对照组儿童（P〈0．05、P〈0．01）。②PI型、CT型ADHD儿童视觉图形工作记忆、视觉空间工作记忆各项指标均显著低于对照组（P〈0．05、P〈0．01），且PI型、CT型ADHD儿童在图形记忆正确数、相反顺序点圆数低于HI型ADHD儿童（P〈0．05）。结论：不同亚型ADHD儿童存在明显的视觉图形记忆、视觉空间记忆处理能力不足，执行功能损害，而且各亚型之间的损害程度有所不同。

英文摘要：

Objective： To find out response characters and differences of Vision Working Memory Test among three different subtypes ADHD and the age -matched normal controls. Methods： 102 ADHD subjects （Predominantly inattentive type, PI： 59 cases; Predominantly hyperactive/impulsive type, HI： 20 cases; Combined type, CT： 23 cases） age from 6 -12 and 102 normal children in the control group were included in this study. All children examed the Vision Working Memory Test. Results： ①Compared to the normal control group, the vision graph memory and vision space memory of ADHD group showed significantly lower （P 〈 0. 05, P 〈 0. 01 ） . ②Compared to every group, PI type and CT type were less in the scores of all indices of vision graph memory and vision space memory than the normal control group （ P 〈 0. 05, P 〈 0. 01 ） . And PI type and CT type were less in the number of vision graph memory and the number of opposite order pointing circle than HI type （P 〈 0. 05） . Conclusion： Results indicate that children with ADHD have significantly visiongraph memory and vision space memory dciency and executive -function impairment. And there are different impairment characters among three different subtypes ADHD.
