The Copenhagen acute headache clinic offered an opportunity to record EEG during migraine attacks in eleven patients with common migraine and ten patients with classical migraine. The median duration of the attacks was 9 h in common migraine. Three patients were studied during prodromes of classical migraine and seven in the early headache phase. The EEG was recorded in the resting state, during hyperventilation and during photic stimulation. No abnormalities were encountered in patients with common migraine nor in eight patients with classical migraine. In two patients with classical migraine mild abnormalities were seen during prodromes and in the early headache phase, but they were also present at a control EEG taken outside an attack. The present study indicates that migraine attacks are rarely associated with EEG abnormalities.
哥本哈根急性头痛诊所为11例普通偏头痛患者和10例典型偏头痛患者在偏头痛发作期间记录脑电图提供了机会。普通偏头痛发作的中位持续时间为9小时。3例患者在典型偏头痛的前驱期接受研究，7例在头痛早期接受研究。脑电图在静息状态、过度换气期间和光刺激期间进行记录。普通偏头痛患者以及8例典型偏头痛患者均未发现异常。2例典型偏头痛患者在前驱期和头痛早期出现轻度异常，但在发作间期进行的对照脑电图检查中也有这些异常。本研究表明，偏头痛发作很少与脑电图异常相关。
