Abstract:
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.
