The WHO is poised to classify what they are calling “gaming disorder” as a mental health problem, where according to the organization’s draft, it can be diagnosed if it “is of sufficient severity to result in significant impairment in personal, family, social, educational, occupational or other important areas of functioning,”
Basically if you do enjoy video games every now and then, this classification probably does not concern you. However if you find yourself losing control when you play games where there is an “increasing priority give to gaming to the extent that gaming takes precedence over other life interests and daily activities,” then perhaps you might have a problem.
We have heard some pretty tragic stories in the past where some gamers get so addicted to video games where they end up neglecting their health to the point where they collapse and die, or where they end up neglecting the health and welfare of others, leading to their death.
