Persistent or recurrent" behavior pattern of "sufficient severity to result in significant impairment in personal, family, social, educational, occupational or other important areas of functioning."
In my opinion its not a real health disorder because it apply's to almost every gamer who likes or plays video games in themselves
Most kids play video games and its not like everyone will stop playing them. Unless you have some issues and is effected by games like call of duty ww2 and viloent games like that.
Youtuber's like mark and jack are effected by this because there channels are revolved around gaming and that's how they make a living.So no i do not think that they can call gaming a disorder.
But it can be used as education like khan academy.
Most people who should be informed about this is parents and not so much kids because if kids play for only so long and they know they are not addicted to the game they are fine.But sadly its gonna be offending to most people who use twitch and other streaming of video games. Mostly youtuber's should be informed about this "disorder".
