The first case of epileptiform seizures related to a
video game was reported in 1981.
[6] Since then, "many cases of seizures triggered by VGs were reported, not only in photosensitive, but also in nonphotosensitive children and adolescents with epilepsy.....Specific preventive measures concerning the physical characteristics of images included in commercially available VGs (flash rate, choice of colors, patterns, and contrast) can lead in the future to a clear decrease of this problem."
[6] Risks can be reduced through measures such as keeping a safe distance away from the screen (at least 2 meters).

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.
[7] Laws requiring PSE warnings be displayed on packages and/or stores have been proposed
[8] and legal firms are keeping an eye on developments.
