Visual evoked potentials (VEPs) were performed in a blind fashion in 114 children aged 3 to 17 years with different types of headaches, in order to investigate whether this could be helpful in the diagnosis of migraine versus other types of headaches in children. The study showed that the amplitude between P100 and N2 was significantly larger in children with migraine headaches (mean 19.8 microvol, SD 7.75) compared with other types of headaches (mean 13.1 microvol, SD 7.45). These results suggest that the sensitivity of VEP P100 amplitude to distinguish migraine headaches in children is 67%, the specificity of VEP is 83%, and the predictive positive value is 83%. VEP study might be helpful in work-up of a child with headache, particularly a young child, when signs and symptoms may not be characteristic.
对114名3至17岁患有不同类型头痛的儿童进行了盲法视觉诱发电位（VEP）检测，以研究其是否有助于儿童偏头痛与其他类型头痛的诊断。研究表明，与其他类型头痛的儿童（平均13.1微伏，标准差7.45）相比，偏头痛儿童P100与N2之间的波幅明显更大（平均19.8微伏，标准差7.75）。这些结果表明，VEP P100波幅区分儿童偏头痛的敏感性为67%，VEP的特异性为83%，预测阳性值为83%。当体征和症状不典型时，VEP研究可能有助于对头痛儿童，尤其是幼儿进行检查。
