A study was made of 58 children with learning disorders, in all of whom a spontaneous EEG as well as a Visual Evoked Response (VER) was registered. The latencies in the secondary complex of the VER were increased and the amplitudes of waves II and III were increased as compared with normal subjects. Two subgroups--children with a good and children with a poor clinical test score--did not differ in VER parameters. A spontaneous EEG evaluated as abnormal was present in 45% of the children. These children showed more absence of peaks in both VER complexes and more increased latencies in the primary complex than children with a normal EEG. The findings show that the VER is a valuable supplement to EEG in demonstrating organic changes in children with learning disorders.
对58名学习障碍儿童进行了研究，所有儿童均记录了自发脑电图以及视觉诱发电位（VER）。与正常受试者相比，VER次级复合波的潜伏期延长，波II和波III的波幅增加。两个亚组——临床测试成绩好的儿童和成绩差的儿童——在VER参数上没有差异。45%的儿童自发脑电图评估为异常。与脑电图正常的儿童相比，这些儿童在两个VER复合波中出现波峰缺失的情况更多，并且初级复合波的潜伏期延长得更多。研究结果表明，在显示学习障碍儿童的器质性变化方面，VER是脑电图的一项有价值的补充。
