摘　　要：为探索儿童注意障碍、多动综合征(ADHD)的客观诊断依据,我们记录并分析了36例ADHD 患儿在两种不同注意状态(主动注意和被动注意)视觉诱发电位(VEP)晚成分的变化。结果为正常组主动注意状态 P_3波出现率较被动注意状态高,主动一被动注意状态间 VEP 的 N_1-P_2波幅变异小,但轻、中、重之间 N_1-P_2波幅变异有区别且逐渐减小。观察证明,ADHD 患儿的主动注意力较正常儿差,VEP 晚成分检查可以作为 ADHD 诊断的客观指标。In this paper,the visual evoked potential(VEP)was recorded in 36 children with atten- tion deficit hyperactivity disorder(ADHD)under two different attentive conditions (active-ignored atten- tion).The result showed that in normal subjects,the P_3—wave was more emerged in active attention than in ignored attention,the amplitude difference of N_1-P_2(VEP)between the active and ignored atten- tion was small.In contrast,the P_3-wave emergent frequency in ADHD children presented little differ- ence and the amplitude difference of N_1-P_2(VEP) between the two different conditions was not signifi- cant.However,the amplitude difference of N_1—P_2 among the mild,middle and severe patients was grad- ually decreased.The findings suggested that the ADHD children have a lower active attention and the VEP is helpful to the diagnosis of ADHD.
