Patients with migraine-associated vertigo (MAV) may have a higher incidence of photic-driven electroencephalography (EEG) response. The occurrence of photic-driven responses for stimulation at frequencies of 10, 12, and 15 Hz can be considered a positive indicator for MAV. Although photic driving is not specific to migraine, patients with MAV have a higher incidence of photic driving. The distinction between Ménière's disease and MAV by means of EEG would be another interesting topic of research.
The objective of this study was to distinguish between patients with MAV and patients with other vestibulopathies (VPs) using EEG.
EEG with intermittent photic stimulation (PS) at frequencies between 3 and 24 Hz was recorded to quantify photic driving in patients with MAV (n = 21) and VPs (n = 15). The presence or absence of photic driving was determined; a score of 1 was counted for response to a particular frequency.
Total scores were calculated for each patient for statistical comparison. There was a significant difference in the average total score between MAV and VP patients (p < 0.05), and photic-driven responses were observed for 10, 12, and 15 Hz stimulation.
偏头痛相关性眩晕（MAV）患者可能有更高的光驱动脑电图（EEG）反应发生率。对于10、12和15Hz频率刺激出现光驱动反应可被视为MAV的一个阳性指标。虽然光驱动并非偏头痛所特有，但MAV患者的光驱动发生率更高。通过脑电图区分梅尼埃病和MAV将是另一个有趣的研究课题。
本研究的目的是使用脑电图区分MAV患者和其他前庭病变（VP）患者。
记录在3至24Hz频率下进行间歇性光刺激（PS）时的脑电图，以量化MAV患者（n = 21）和VP患者（n = 15）的光驱动情况。确定是否存在光驱动；对特定频率的反应计为1分。
计算每位患者的总分以进行统计比较。MAV患者和VP患者的平均总分存在显著差异（p < 0.05），并且在10、12和15Hz刺激下观察到了光驱动反应。
