Television (TV) and video games (VG) can provoke seizures in patients with photosensitive epilepsies. Flicker frequency is the most important factor in screen activation. We tested conventional 50-Hz versus 100-Hz monitors during TV viewing and VG playing in 30 photosensitive subjects, 23 of whom had a history of TV or VG seizures or both. Fifteen subjects' discharges were activated by 50-Hz TV; 17 by 50-Hz VG; and one by a 100-Hz screen. Thus, 100-Hz screens protect against screen activation.
电视（TV）和电子游戏（VG）可诱发光敏性癫痫患者发作。闪烁频率是屏幕激活的最重要因素。我们在30名光敏性受试者观看电视和玩电子游戏时，对传统的50赫兹与100赫兹显示器进行了测试，其中23人有电视或电子游戏诱发癫痫发作的病史。15名受试者的放电由50赫兹电视激活；17名由50赫兹电子游戏激活；1名由100赫兹屏幕激活。因此，100赫兹屏幕可防止屏幕激活。
