The International Classification of Diseases contains codes as well as signs and symptoms of diseases and disorders to be used by healthcare and clinicians across the globe. It's called gaming disorder, and it's described by "a pattern of persistent or recurrent gaming behavior", or all the more essentially, a dependence on gaming.
The disorder is not characterized by playing a video game here or there, but rather by lack of ability to control when one games, "increasing priority give to gaming to the extent that gaming takes precedence over other life interests and daily activities", and continuing to game avidly despite having negative consequences for doing so.
These symptoms normally must appear over a period of 12 months for a diagnosis, though it may be diagnosed in a shorter amount of time depending on the severity.
The ICD - a diagnostic manual that's published by the World Health Organization - was last updated 27 years ago, in 1990.
Newsweek writes that gaming addiction has not been recognized as an official condition in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5).
"Most people who play video games don't have a disorder, just like most people who drink alcohol don't have a disorder either".
There's no denying that as the gaming industry continues to grow, so does the controversy surrounding whether or not games are risky for your health. But ICD-11, which will be rolled out in 2018, will include a new proposed class of mental conditions called "gaming disorder". But as with everything, moderation is key.
