Abstract:
Objective To compare the event-related potential(ERP) difference waveforms between attention deficit hyperactivity disorder (ADHD) children and normal children in the conflict task,and to investigate the neural mechanism of conflict monitoring of ADHD. Methods ERPs elicited by performing the spatial SimonStroop task were recorded in 32 children with ADHD and 32 normal children. The differences of ERP and behavior dren with ADHD(0.80±0. 11 ,0.87 ±0.08) were less than normal children (0.88 ±0.07,0.93 ±0. 04)in Sireaction time of ADHD group( (773.03 ±99.34)ms) in the Siin were longer than the control group( (737.21 ±81.40)ms) ,the differences had statistic significance (P＜0. 05). 2. ERP results:the amplitude of N2 of the children with ADHD in the four conditions were smaller than the control group, the difference in Siin had statistic sigof prefrontal and anterior cingulate cortex of ADHD were weaker than the control group. Conclusions The results suggest that, due to the inadequate allocation of attention resources of the children with ADHD, they have conflict monitoring function defects compare with normal children. The function defects of conflict information processing related brain areas may be the main neural mechanism. The result of the behavior and ERP can become the reference indicator for the early diagnosis and treatment of ADHD.
