while computer displays in general present very little risk of producing seizures in pse patients (much less risk than that presented by television sets), video games with rapidly changing images or highly regular patterns can produce seizures, and video games have increased in importance as triggers as they have become more common. some people with no prior history of pse may first experience a seizure while playing a video game. often the sensitivity is very specific, "e.g.," it may be a specific scene in a specific game that causes seizures, and not any other scenes. despite this, there are questions on the dangers of this, and calls for testing all video games for causing pse.
