Will video games cause seizures in my children?

Posted under Ask the Mediatrician.

Q: The manual for my teenage son’s favorite video game contains a warning that says that some games cause seizures and that parents should watch for seizure symptoms or ask their children if they’ve experienced any symptoms while playing. I can’t monitor every minute of game play, and if I asked my son about it, I’m not sure he would admit any symptoms to anything he thought might lead me to limit his game time. How worried should I be?
