The incidence of 'telephillic syndrome' (impulsive attraction to television), in three photosensitive epileptic patients who were referred to our neurophysiology clinic because they were having seizures is reported. Two were females, aged fourteen and eight respectively, one was a male aged twenty-five years. All the patients had a family history of epilepsy. The age range of onset of photosensitivity was 3.5-12 years and the most common seizure inducing factor was flickering light from the television (TV) viewing. They were all 'telephillic'. The predominant seizure type found in these patients was tonic-clonic seizure. Comprehensive electroencephalographic (EEG) investigation was carried out including hyperventilation. The basic EEG showed abnormal spike and wave activity on eye opening and eye closure in all the patients. Intermittent photic stimulation (IPS) evoked occipital spikes and photoparoxysmal response (PPRs) at a photosensitivity range of 758 flashes per second (fps). Pattern sensitivity test using a Gratings pattern revealed a sensitivity range of 1.03-3.5 cycles per second (cpd). And the predominant area of brain activity was the right mid-post temporal regions. Binocular stimulation offered no protection in one patient.
本文报告了3例光敏性癫痫患者“电视癖综合征”（对电视产生冲动性迷恋）的发病率，这3例患者因癫痫发作被转诊至我们的神经生理学诊所。其中2例为女性，分别为14岁和8岁，1例为25岁男性。所有患者均有癫痫家族史。光敏性发作的年龄范围为3.5至12岁，最常见的诱发癫痫发作的因素是看电视时电视发出的闪烁光。他们都患有“电视癖”。这些患者中最主要的癫痫发作类型为强直阵挛发作。进行了包括过度换气在内的全面脑电图（EEG）检查。基础脑电图显示，所有患者在睁眼和闭眼时均出现异常的棘波和慢波活动。间歇性光刺激（IPS）在每秒758次闪光（fps）的光敏范围内诱发枕叶棘波和光阵发性反应（PPRs）。使用光栅图案进行的图形敏感性测试显示，敏感性范围为每秒1.03至3.5个周期（cpd）。大脑活动的主要区域是右侧颞叶中后区域。双眼刺激对1例患者没有起到保护作用。
