目的探讨注意缺陷多动障碍(ADHD)儿童视觉信息整合能力及视觉工作记忆能力,进一步揭示其脑认知功能.方法采用1∶1病例对照研究方法选取45例5～14岁ADHD儿童及对照组进行空间轮廓整合能力、空间位置噪声、时序记忆、模式记忆测试.结果 ADHD儿童空间轮廓整合能力左右眼成绩分别为[(1.62±0.81)分,(1.69±0.87)分],低于对照儿童左右眼成绩[分别为(2.02±1.10)分,(1.98±0.81)分],差异有显著性(P＜0.05).空间位置噪声左右眼成绩[分别为(1.98±0.89)分,(2.20±1.10)分]低于对照儿童左右眼成绩[分别为(2.20±0.97)分,(2.30±0.83)分],差异无显著性(P＞0.05).时序记忆及模式记忆的完成能力[分别为(1.89±1.30)分,(1.18±0.44)分]低于对照组儿童[分别为(2.98±1.25)分,(1.44±0.66)分],差异有显著性(P＜0.05).结论 ADHD儿童存在视觉知觉、视觉信息整合能力方面的缺陷,ADHD儿童存在视觉工作记忆处理能力缺陷、存在执行功能障碍.

Objective To find out the brain function characters of visual information integration and visual working memory with attention deficit hyperactivity disorder (ADHD) children. Methods 1∶ 1 case-control study was used on the study. 45 ADHD children who met DSM-IV criteria were recruited as case group,45 normal children from primary school were chosen as control group. Two groups children received the test of contour-integration,positional noise, temporal order memory, pattern memory. Results The ADHD double eyes' contour integration ( ( 1.62 ± 0. 81 ), ( 1.69 ± 0.87 ) ) were significantly lower than the control group' ( (2.02 ± 1.10), ( 1.98 ±0.81 )). There was no significant difference of double eyes' positional noise between case group( (1.98 ±0.89 ), ( 2.20 ± 1.10 ) ) and the control group ( ( 2.20 ± 0. 97 ), ( 2.30 ± 0. 83 ) ). The temporal order memory,pattern memory ( ( 1.89 ± 1.30), ( 1.18 ± 0.44) ) showed significantly lower in case group(P＜ 0.05 ) than that in control group ( ( 2.98 ± 1.25 ), ( 1. 44 ± 0. 66) ). Conclusion Results indicate that children with ADHD have deficiency in visual perception and the ability of visual information integration, and have significantly deficiency in visual working memory and executive-function.
