The diagnosis of acephalgic migraine is complicated by the fact that other neurological conditions such as transient ischaemic attacks, demyelinating disease, simple partial epilepsy, and even glaucoma, can present with similar symptoms. Using both flash and pattern stimulation, visual evoked potentials (VEPs) were examined as a means of differentiating between acephalgic migraine, migraine with aura, migraine without aura, demyelinating disease and a control group. This study demonstrated that by analysing the amplitude of the background fast activity in the flash and pattern VEP, acephalgic migraine can be differentiated from demyelinating disease, migraine with aura, migraine without aura and absolute controls.
无头痛性偏头痛的诊断较为复杂，因为其他神经系统疾病，如短暂性脑缺血发作、脱髓鞘疾病、单纯部分性癫痫，甚至青光眼，都可能表现出类似症状。使用闪光和图形刺激，对视诱发电位（VEP）进行检测，以此作为区分无头痛性偏头痛、有先兆偏头痛、无先兆偏头痛、脱髓鞘疾病和对照组的一种方法。这项研究表明，通过分析闪光和图形VEP中背景快速活动的振幅，可以将无头痛性偏头痛与脱髓鞘疾病、有先兆偏头痛、无先兆偏头痛以及绝对对照区分开来。
