The Internet can foster various addictions including addiction to<unk> playing. Addictive playing of MMORPGs is associated with negative effects, whereas normal play is not. Younger people and men are more likely to experience a gaming disorder than older people and women respectively. Adolescents are at a higher risk of sustaining<unk> <unk>  disorder over time than adults. An international meta-analysis over 34 jurisdictions quantified the effect size of gender as small, with most effect in Asia, lesser in Europe and Africa, and null in North America, and further finding that economic factors, internet availability, social norms and addiction-related health factors mediate the effect of gender, with nations with a greater GDP per capita having less differences in<unk>  between genders. Comorbid psychiatric disorders act as both risk factors and consequences. Indeed, there is a strong association between<unk>  and anxiety, depression, ADHD, social phobia, and poor psycho-social support. ADHD and its symptoms, such as impulsivity and conduct problems, also increase risks of developing<unk> <unk>  disorder. Although internet gaming disorder has a strong relationship with obsessive-compulsive disorder, it is not specific and internet gaming disorder is both phenomenologically and neurobiologically distinct, which indicates that internet gaming disorder is more characterized by impulsivity than compulsivity. Familial factors appear to play an important role, although not well understood. Some personality traits, such as high neuroticism, high impulsivity, and high aggressiveness are consistently significant predictors of internet gaming disorder, and combination of personality traits seem to play a pivotal role in the acquisition, maintenance and development of the disorder.
