prioritizing gaming over other interests and activities
continuing gaming despite its negative consequences.

These behaviors must be so severe that they affect a person’s:

family life
social life
personal life

anxiety disorders
depression
stress

People who remain physically inactive for extended periods due to gaming may also have a higher risk of obesity, sleep problems, and other health issues.
Addiction to gaming is similar in many ways to other types of addiction. People with the disorder often spend many hours playing games, have a strong emotional attachment to this behavior, and may experience fewer social connections as a result.
