少数病人,在特定的外界因素刺激下,如突然的声音,光线强度的改变,皮肤受刺激,突然起立和行走速度加快,甚至复杂的思维活动如奕棋与打扑克时,可以有癫痫发作。这些因素往往为一种感觉性刺激,所以称为感觉诱发性癫痫,又称为反射性癫痫。其中尤以光敏性癫痫为最常见。自50年代以来,又有一些病例在观看电视时有癫痫发作的报道。 A small number of patients may have seizures under the influence of certain external factors, such as sudden sound, light intensity changes, skin irritation, sudden rise and walking speed, and even complicated thinking activities such as chess and playing poker. These factors are often a sensory stimulation, so called sensory-induced epilepsy, also known as reflex epilepsy. Among them, photosensitive epilepsy is the most common. Since the 1950s, there have been a number of reports of seizures while watching television.
