The specific type of gaming disorder (GD) that is the focus of this review is "disordered video-gaming," or more precisely the addictive potential of interactive video games played on mobile phones, gaming consoles, individual computers, and over networks. Certain characteristics of such games, including structured rewards and multi-modal sensory stimulation, contribute to that addictive potential. Networked games also allow for direct social engagement through role playing and cooperation with others. They also lead to further opportunities for participation in a wider community of players on forums outside gameplay, such as discussion platforms, video play-through analyses, or live-streaming.
The authors performed a systematic search of the peer-review literature, and identified 29 studies exploring the relationship between Addend GD.
All studies found a positive association between ADHD and GD. Of studies reporting effect sizes, seven reported small effect sizes, three reported medium ones, and three reported large ones. There was a similarly wide variety of reported effect sizes among studies that reported correlations between ADHD scales and GD scales. These ranged from r = .12 (small) to r = .45(large).
Three studies examined longitudinal outcomes. One reported that lower ADHD scores at baseline predicted positive long-term recovery. Another noted that GD was more likely to develop into significant psychiatric symptoms and poorer educational outcomes two years later. The third study found that higher ADHD and GD scores were associated with higher incidences of delinquent or aggressive behaviors and externalizing problems, as compared to a sample with ADHD but not GD. All three studies reported that ADHD was a risk factor for the development of problematic gaming behavior. There was no clear indication of the reverse relationship - GD predicting ADHD.
The authors concluded, "This review found a consistent positive association between ADHD and GD, particularly for the inattention subscale. The strength of the association between ADHD and GD was variable. On symptom severity ratings, there was a positive relationship between scores measuring GD and ADHD pathology in some studies. Fewer studies in this review showed hyperactivity was commonly associated with GD. It is well known that hyperactivity in ADHD tends to improve significantly with age. It is possible that the natural progression of the disorder resulted in lower rates of hyperactivity. Such a hypothesis is strengthened by findings of a stronger association with hyperactivity among children aged between 4 and 8."
Ideas for policy interventions to address disordered video gaming include:
· Parental controls on games.
· Warning messages similar to those on cigarette packaging.
· Organizing help services for gamers.
The authors called for further study on:
· Effectiveness of intervention strategies.
· The contribution of GD to the dysfunction associated with ADHD.
· The relationship between the content of play (e.g., violence) and motivation to play (e.g., escapism) and ADHD symptoms.

"Clinicians should beware that ADHD is common in GD," the authors emphasized, "and we, therefore, recommend that ADHD is screened for when evaluating GD as part of routine practice. This would ensure interventions aimed at ADHD can be successfully combined with GD treatment, potentially improving patient outcomes."
