Abstract

Background: We carried out a clinical and electroencephalographic (EEG) study to reveal the pathophysiology of acute symptoms elicited by a TV animation program.

Methods: Clinical data and EEG were obtained from 20 patients ranging in age from 6 to 30 years. A pattern presentation and an intermittent photic stimulation were performed.

Results: Of 20 patients, 13 had a convulsion and seven had other symptoms, mainly nausea and/or vomiting. A photoparoxysmal response (PPR) was confirmed in 12 of 13 patients (92.3%) who had a convulsion. Only one of seven patients (14.3%) without a convulsion showed a PPR. The incidence of PPR was significantly higher in patients with convulsion than those without convulsion. There were no significant differences in the family history of convulsion, gender, parameters associated with TV watching and basic EEG between the two groups. All patients with PPR had a convulsion or consciousness disturbance.

Conclusion: Acute symptoms, such as convulsion and impairment of consciousness, are supposed to be based on photosensitivity.

电视动画引起的光敏痉挛:一项脑电图研究。

背景:我们进行了临床和脑电图(EEG)研究，以揭示由电视动画节目引起的急性症状的病理生理学。方法:收集20例6 ~ 30岁患者的临床资料及脑电图资料。进行模式展示和间歇性光刺激。结果:20例患者中，13例有抽搐，7例有其他症状，主要是恶心和/或呕吐。13例惊厥患者中有12例(92.3%)发生光性发作反应(PPR)。7例无惊厥的患者中仅有1例(14.3%)出现小反刍兽疫。惊厥患者PPR的发生率明显高于无惊厥患者。两组惊厥家族史、性别、电视相关参数及基本脑电图无显著差异。所有小反刍兽疫患者均有惊厥或意识障碍。结论:急性症状，如惊厥和意识障碍，应以光敏性为基础。
