The case of a 25-year-old white male, who had migrainous headaches each time he sat in front of his personal computer screen, is described. Changing the screen frequency from 60 to 75 Hz through a Windows command could abolish the headaches. In several surveys, computer screens have been reported to be a migraine trigger. We hypothesize that this environmental trigger may be related to the abnormal flicker fusion thresholds that have been described in migraineurs. It may be that modifying the frequencies of light sources, such as computer screens, could become a non-pharmacological approach to prevent migraine attacks.
本文描述了一名25岁白人男性的病例，他每次坐在个人电脑屏幕前都会出现偏头痛。通过Windows命令将屏幕频率从60赫兹改为75赫兹可以消除头痛。在几项调查中，电脑屏幕被报告为偏头痛的触发因素。我们推测，这种环境触发因素可能与偏头痛患者中描述的异常闪烁融合阈值有关。也许改变光源频率，如电脑屏幕的频率，可能成为预防偏头痛发作的一种非药物方法。
