We have tried to ascertain whether the increased visual evoked potential (VEP) amplitude found in adult migraineurs is present also in children with migraine. We investigated 43 children, 26 male and 17 female, with a mean age of 11.4 years, 24 with common and 19 with classic migraine, and compared them with a control group of 20 children, 11 male and 9 female, with a mean age of 9.7 years. Flash and pattern reversal VEPs were recorded in both groups, and the study was carried out in the pain-free interval between attacks. The children with migraine showed a significant (p less than 0.01) increase in VEP amplitude on flash stimulation but not on pattern reversal. There were no differences between classic and common migraine. The abnormal responsiveness of the visual system seems to be related to variations in light intensity rather than to spatial contrasts.
我们试图确定在成年偏头痛患者中发现的视觉诱发电位（VEP）振幅增加在偏头痛儿童中是否也存在。我们调查了43名儿童，其中26名男性和17名女性，平均年龄为11.4岁，24名患有普通偏头痛，19名患有典型偏头痛，并将他们与20名儿童组成的对照组进行比较，对照组中有11名男性和9名女性，平均年龄为9.7岁。两组均记录了闪光和图形翻转VEP，并且该研究是在发作间期无痛状态下进行的。偏头痛儿童在闪光刺激时VEP振幅显著增加（p小于0.01），但在图形翻转时没有增加。典型偏头痛和普通偏头痛之间没有差异。视觉系统的异常反应似乎与光强度的变化有关，而不是与空间对比度有关。
