The World Health Organization (WHO) might classify "gaming disorder" as a mental health condition in its 2018 manual on diseases.

In the beta draft of the WHO's 11th update of International Classification of Diseases (ICD-11), gaming disorder has been included in the category of "mental, behavioral or neurodevelopmental disorders."

To warrant a diagnosis of such a disorder, one shall have "impaired control over gaming," and give "increasing priority to gaming to the extent that gaming takes precedence over other life interests and daily activities," and continue gaming "despite the occurrence of negative consequence," according to the draft.

Such a behavior pattern is of sufficient severity to result in significant impairment in personal, family, social, educational, occupational or other important areas of functioning, says the ICD-11.

The ICD is used by health professionals globally and serves as an international standard for defining health conditions and diseases.

Sudden deaths and physical symptoms linked to online gaming are on the rise in recent years.

In 2014, a 27-year-old Chinese woman suffered a sudden death after playing video games for over 10 consecutive hours.
