In 2018, the World Health Organization (WHO) released the 11th revision of the International Classification of Diseases (ICD-11). This revision included a statement regarding gaming behavior as follows:

Gaming disorder is defined as a pattern of gaming behavior (“digital-gaming” or “video-gaming”) characterized by impaired control over gaming, increasing priority given to gaming over other activities to the extent that gaming takes precedence over other interests and daily activities, and continuation or escalation of gaming despite the occurrence of negative consequences.

For gaming disorder to be diagnosed, the behavior pattern must be of sufficient severity to result in significant impairment in personal, family, social, educational, occupational or other important areas of functioning and would normally have been evident for at least 12 months.

The inclusion of gaming disorder in ICD-11 follows the development of treatment programs for people with health conditions identical to those characteristic of gaming disorder in many parts of the world, and will result in the increased attention of health professionals to the risks of development of this disorder and, accordingly, to relevant prevention and treatment measures.

Note: The WHO’s definition of gaming disorder intentionally omits games that have gambling elements built in.
