Video games may eat into time spent on more conventional socialising or other recreational pursuits. And there is concern that they may be addictive. The American Medical Association considered recognising the existence of video game addiction in 2007, and although it ultimately rejected this idea, there are already clinics treating this addiction in Holland and South Korea. Like almost all compulsive activities, gaming increases levels of dopamine in the brain, and because of their combination of structured tasks and regular rewards, certain kinds of games produce especially high levels of dopamine. A study at Stanford University suggests that men are more likely than women to respond compulsively to games, while a poll of US children and teenagers concluded that 8.5 percent of youth gamers could be classified as addicted to playing video games.
