摘要目的 研究注意缺陷多动障碍(ADHD)患儿空间忽视的现象.方法 对32例男性ADHD患儿和32例正常儿童进行划星试验、线等分试验,以及智能测验等非忽视测验.结果 (1)ADHD患儿线等分测试结果为(-9.37±6.57),与对照组(-5.46±4.69)相比,差异有统计学意义(t=-2.735,P<0.01);ADHD患儿左侧划星试验成绩(11.44±5.55)差于对照组(16.34±4.82)(t=-3.78,P<0.01),且左侧较右侧(17.13±6.36)差,差异均有统计学意义(t=-3.09,P<0.01).(2)两组儿童线等分测验成绩均偏向"0"值的右侧(ADHD组t=-8.064,P<0.01;对照组t=-6.585,P<0.01),两侧划星测验成绩也较"正常值""27/27"差(ADHD组:左侧t=15.85,P<0.01;右侧t=-8.78,P<0.01.对照组:左侧t=-12.52,P<0.01;右侧t=-7.39,P<0.01).结论 ADHD患儿较正常儿童存在明显左侧空间忽视现象.

abstractsObjective To detect unilateral spatial neglect phenomenon in children with attention deficit hyperactivity disorder(ADHD)and to test the hypothesis that the phenomenon is associated with ADHD.Methods Thirty two boys met with ADHD diagnostic criteria of DSM-ⅣTM(ADHD group)and the 32 healthy boys without ADHD as control group participated in this study.All the participants received the flowing managements.The spatially sensitive tools of the Line Bisection test and the Star Cancellation test and some general measures(non-spatial)were used to evaluate spatial attention.Results(1)The score of Line Bisection test of boys with ADHD was(-9.37±6.57),and that of the control group was(-5.46±4.69),the difference between two groups was significant(t=-2.735,P<0.01):the difference in left side score of the Star Cancellation test was statistically significant(t=-3.78,P<0.01)in the ADHD group versus the control group(11.44±5.55 vs.16.34±4.82),and the left side score was also lower than the right side one(17.13±6.36),the difference was significant(t=-3.09,P<0.01).(2)Both groups'scores of the Line Bisection test were biased to the right side of"O"valne respectively (ADHD group:t=-8.064,P<0.01;control group:t=-6.585,P<0.01),each side of which was lower versus"expected value""27/27"on right side (ADHD group:t=-8.78,P<0.01;control group:t=-7.39,P<0.01) and left side (ADHD group:t=15.85,P<0.01;control group:t=-12.52,P<0.01).Conclusions The results suggest that left spatial neglect may be a common general phenomenon of school age boys.Compared with normal children,children with ADHD may have obvious left spatial neglect.which suggest that there be a common neurophysiologic mechanism between left spatial bias and ADHD.
