Video game addiction is a real condition, WHO says. Here's what that means.

The World Health Organization on Monday officially recognized "gaming disorder" as a condition in its International Classification of Diseases, saying that it is possible to be addicted to video games. Simply playing a lot of video games does not automatically mean that someone has a problem. The hallmark of the disorder is that playing games overtakes other desires, and that it continues or escalates despite negative consequences. A diagnosis would have to include evidence of this type of behavior lasting for more than 12 months, the organization said. The disorder affects no more than 3 percent of gamers, the Associated Press reported, with some estimates as low as 1 percent.
