Abstract
Children’s use of electronic media, including Internet and video gaming, has increased dramatically to an average in the general population of roughly 3 h per day. Some children cannot control their Internet use leading to increasing research on “internet addiction.” The objective of this article is to review the research on ADHD as a risk factor for Internet addiction and gaming, its complications, and what research and methodological questions remain to be addressed. The literature search was done in PubMed and Psychinfo, as well as by hand. Previous research has demonstrated rates of Internet addiction as high as 25% in the population and that it is addiction more than time of use that is best correlated with psychopathology. Various studies confirm that psychiatric disorders, and ADHD in particular, are associated with overuse, with severity of ADHD specifically correlated with the amount of use. ADHD children may be vulnerable since these games operate in brief segments that are not attention demanding. In addition, they offer immediate rewards with a strong incentive to increase the reward by trying the next level. The time spent on these games may also exacerbate ADHD symptoms, if not directly then through the loss of time spent on more developmentally challenging tasks. While this is a major issue for many parents, there is no empirical research on effective treatment. Internet and off-line gaming overuse and addiction are serious concerns for ADHD youth. Research is limited by the lack of measures for youth or parents, studies of children at risk, and studies of impact and treatment.

Some children cannot control their Internet use leading to increasing research on “internet addiction.” The objective of this article is to review the research on ADHD as a risk factor for Internet addiction and gaming, its complications, and what research and methodological questions remain to be addressed. The literature search was done in PubMed and Psychinfo, as well as by hand. Previous research has demonstrated rates of Internet addiction as high as 25% in the population and that it is addiction more than time of use that is best correlated with psychopathology. Various studies confirm that psychiatric disorders, and ADHD in particular, are associated with overuse, with severity of ADHD specifically correlated with the amount of use. ADHD children may be vulnerable since these games operate in brief segments that are not attention demanding. In addition, they offer immediate rewards with a strong incentive to increase the reward by trying the next level. The time spent on these games may also exacerbate ADHD symptoms, if not directly then through the loss of time spent on more developmentally challenging tasks. While this is a major issue for many parents, there is no empirical research on effective treatment. Internet and off-line gaming overuse and addiction are serious concerns for ADHD youth. Research is limited by the lack of measures for youth or parents, studies of children at risk, and studies of impact and treatment.</p></abstract><kwd-group><title>Keywords</title><kwd>ADHD</kwd><kwd>Children</kwd><kwd>Computer use</kwd><kwd>Internet addiction</kwd><kwd>Gaming</kwd></kwd-group><custom-meta-group><custom-meta><meta-name>issue-copyright-statement</meta-name><meta-value>© Springer-Verlag 2011</meta-value></custom-meta></custom-meta-group></article-meta></front><body><sec id="Sec1"><title>Introduction</title><p>The past decade has seen an exponential growth in the use of Internet, video games, downloadable television, music and movies, and social networking (Media Awareness Network <xref ref-type="bibr" rid="CR62">2005</xref>; Smith et al. <xref ref-type="bibr" rid="CR83">2009</xref>). This change in our culture has had a marked impact on the development and daily activities of children. From a cognitive point of view, it has increased the use of visual relative to auditory communication and placed a premium on short snippets of communication rather than sentences and paragraphs. Where previously childhood consisted of free play in large group games, many children now live in a world of web-based media that may be foreign to many parents and even more alien to most grandparents. The emergence of this “screen culture” has been a paradigm shift in the world of childhood, and the implications of this bear some thought.</p><p>In 2008, the McCreary Centre Society (Smith et al. <xref ref-type="bibr" rid="CR83">2009</xref>), a non-government, nonprofit organization, provided research on screen time in the general adolescent population in Canada. Results indicated that on an average school day, 25% of youth spent upwards of 3 h watching TV and/or playing on the Internet and 15% played video games for more than 3 h (Smith et al. <xref ref-type="bibr" rid="CR83">2009</xref>). This is similar to another recent study of Canadian youth by Mark et al. showing average daily screen time of 3 h/day (Mark and Janssen <xref ref-type="bibr" rid="CR61">2008</xref>). There is a suggestion that high-risk youth may spend even more time in front of screens, with a recent study showing daily screen time of almost 7 h/day in youth attending a psychiatric clinic (Baer et al. <xref ref-type="bibr" rid="CR7">2011</xref>). If the average child is spending one-third of their day on screen activities and high-risk children are spending most of their leisure hours on screens, risks and benefits must be evaluated from two points of view. First, what is the effect of this degree of exposure? Second, what is the effect of the loss of those activities that have been abandoned in its stead?</p><p>Concerns about overuse of these electronic tools have led to use of the term “internet addiction” (Byun et al. <xref ref-type="bibr" rid="CR11">2009</xref>). Various definitions for Internet addiction have been proposed based largely on criteria for substance abuse and impulse control disorders including compulsive gambling (Beard <xref ref-type="bibr" rid="CR8">2005</xref>; Demetrovics et al. <xref ref-type="bibr" rid="CR26">2008</xref>; Ko et al. <xref ref-type="bibr" rid="CR45">2005b</xref>; <xref ref-type="bibr" rid="CR51">2009c</xref>; Shaw and Black <xref ref-type="bibr" rid="CR78">2008</xref>; Tao et al. <xref ref-type="bibr" rid="CR87">2010</xref>; Fu et al. <xref ref-type="bibr" rid="CR30">2010</xref>). Proposed criteria focus on such factors as children’s preoccupation with Internet activities, their inability to control their use, and their distress when use is limited. Continued use despite interference with other essential activities in children’s lives such as learning, socializing, eating, or sleep is a key factor. There are marked differences of opinion between parents and children about whether Internet gaming is a good use of time, and differences between parents and children in ADHD research in general are endemic in the field. Concern about this phenomenon is widespread, with some arguing it should be included as a “disorder” for the Diagnostic and Statistical Manual V (Block <xref ref-type="bibr" rid="CR10">2008</xref>; Hinic et al. <xref ref-type="bibr" rid="CR36">2008</xref>; Kratzer and Hegerl <xref ref-type="bibr" rid="CR54">2008</xref>; Miller <xref ref-type="bibr" rid="CR64">2007</xref>; Pies <xref ref-type="bibr" rid="CR73">2009</xref>).</p><p>In 2006, Ha and colleagues did an early study that showed out of 455 children and 836 adolescents, 14% of children and 20% of adolescents screened positive for excessive Internet use (Ha et al. <xref ref-type="bibr" rid="CR33">2006</xref>). Similar studies reporting Internet addiction in children and youth have been reproduced around the world: in Korea (Cho et al. <xref ref-type="bibr" rid="CR21">2008</xref>; Park et al. <xref ref-type="bibr" rid="CR72">2008</xref>), Turkey (Ceyhan <xref ref-type="bibr" rid="CR15">2008</xref>), Taiwan (Lin and Yu <xref ref-type="bibr" rid="CR59">2008</xref>; Wan and Chiou <xref ref-type="bibr" rid="CR91">2006</xref>) Czechoslovakia (Simkova and Cincera <xref ref-type="bibr" rid="CR81">2004</xref>), Singapore (Mythily et al. <xref ref-type="bibr" rid="CR66">2008</xref>), Romania (Chirita et al. <xref ref-type="bibr" rid="CR20">2006</xref>), Italy (Coniglio et al. <xref ref-type="bibr" rid="CR22">2007</xref>; Ferraro et al. <xref ref-type="bibr" rid="CR29">2007</xref>), Iran (Ghassemzadeh et al. <xref ref-type="bibr" rid="CR31">2008</xref>), Greece (Siomos et al. <xref ref-type="bibr" rid="CR82">2008</xref>), Norway (Johansson and Gotestam <xref ref-type="bibr" rid="CR38">2004</xref>), and China (Song et al. <xref ref-type="bibr" rid="CR84">2010</xref>; Xu et al. <xref ref-type="bibr" rid="CR94">2008</xref>). Reported rates of addiction typically range between 2 and 20% with some reporting as high as 25% (Zboralski et al. <xref ref-type="bibr" rid="CR102">2009</xref>). A comparative study found significantly higher rates of Internet addiction in China than the United States, suggesting cultural factors may play a role (Jackson et al. <xref ref-type="bibr" rid="CR37">2008</xref>). Baer et al. have shown that the presence of addictive features is correlated with psychopathology and functional impairment, whereas as screen time in the absence of addiction is not (Baer et al. <xref ref-type="bibr" rid="CR7">2011</xref>).</p><p>ADHD is well known to impart an increased risk of substance abuse disorders (Cumyn et al. <xref ref-type="bibr" rid="CR23">2009</xref>; Ohlmeier et al. <xref ref-type="bibr" rid="CR69">2007</xref>, <xref ref-type="bibr" rid="CR70">2008</xref>) as well as impulse control disorders such as compulsive gambling (Lawrence et al. <xref ref-type="bibr" rid="CR58">2009</xref>). This raises the question whether children with ADHD are more at risk of overuse of the Internet or off-line gaming.</p><p>Parents frequently complain about their children spending excessive amounts of time on gaming and the difficulty they experience in getting their child to comply with turning off the game. Children who are not otherwise oppositional may experience extreme rages if a parent pulls the plug in the middle of a game when a child is non-compliant with instructions to turn it off. Parents present clinicians with many questions: “How much time on the computer is reasonable?” “How can I get my child to learn how to turn the computer off?” “If he is on the computer all the time, he’s not playing with other children or playing sports, is this a problem?” While some guidelines on “screen time” have been created (AAP <xref ref-type="bibr" rid="CR1">2001</xref>), clinicians are typically left to rely on their personal opinions in answering many of these questions.</p><p>The objective of this article is to review the research on the relationship between use of the Internet and non-Internet-based (off-line) video gaming with ADHD. This review will address several issues. What research has been done to determine whether ADHD is a risk factor for increased time in front of the computer or gaming station? If so, what do we know about ADHD that might make these children more vulnerable? Is there any suggestion that Internet and gaming may worsen or improve ADHD core symptoms? We will review what has been written about the treatment for overuse of Internet and gaming activities or “internet addiction.” Finally, we will summarize what is known to date, methodological limitations in the research, and possible areas of future study.</p></sec><sec id="Sec2"><title>The relationship between ADHD, the Internet, and off-line video gaming</title><p>While most of the studies on Internet use are cross-sectional, one recent prospective study followed over 2,000 adolescents for 2 years to determine whether the presence of psychiatric symptoms would predict later development of Internet addiction (Ko et al. <xref ref-type="bibr" rid="CR50">2009b</xref>). While depression and social phobia were also associated with later problems (particularly in girls), ADHD was shown to be the most significant predictor for the development of Internet addiction, followed by hostility, after controlling for sex and age. Looking at gender groups separately, hostility was the strongest predictor in boys and ADHD was the strongest predictor for girls.</p><p>This prospective study is consistent with results from several cross-sectional studies looking at the association between ADHD symptoms and Internet addiction (Chan and Rabinowitz <xref ref-type="bibr" rid="CR18">2006</xref>; Ha et al. <xref ref-type="bibr" rid="CR33">2006</xref>; Yen et al. <xref ref-type="bibr" rid="CR95">2007</xref>, <xref ref-type="bibr" rid="CR96">2009</xref>; Yoo et al. <xref ref-type="bibr" rid="CR97">2004</xref>). Yen et al. found that ADHD symptoms correlated with Internet addiction in a sample of over 2,500 college students (Yen et al. <xref ref-type="bibr" rid="CR96">2009</xref>). The strongest association was seen in female students, similar to the results in the Ko et al. prospective study. Similar associations have been found in younger age groups as well, with Yoo et al. showing higher ADHD symptoms in elementary students with Internet addiction (Yoo et al. <xref ref-type="bibr" rid="CR97">2004</xref>). Associations between ADHD and Internet addiction have also been shown in the adolescent population with Yen et al. reporting higher levels of ADHD, depression, and hostility in boys with Internet addiction, and higher levels of ADHD and depression in girls with Internet addiction (Yen et al. <xref ref-type="bibr" rid="CR95">2007</xref>). Chan et al. have noted a correlation between severity of ADHD symptoms (particularly inattention) and time spent on the Internet (Chan and Rabinowitz <xref ref-type="bibr" rid="CR18">2006</xref>).</p><p>ADHD traits such as impulsivity (Cao and Su <xref ref-type="bibr" rid="CR12">2007</xref>; Cao et al. <xref ref-type="bibr" rid="CR13">2007</xref>), extraversion (Mottram and Fleming <xref ref-type="bibr" rid="CR65">2009</xref>), disinhibition (Sun et al. <xref ref-type="bibr" rid="CR86">2009</xref>), and low self-esteem (Niemz et al. <xref ref-type="bibr" rid="CR68">2005</xref>) correlate with Internet use and abuse. One small study directly compared video game playing in children with ADHD versus controls (Bioulac et al. <xref ref-type="bibr" rid="CR9">2008</xref>). Interestingly, there was no difference in frequency or duration of video game play between the two groups. However, the children with ADHD showed higher levels of addiction than controls, suggesting that it is not time so much as the capacity for use to become more driven and problematic that differentiates Internet use in ADHD compared to the general population.</p><p>Further evidence for a connection between ADHD and Internet use is found in a provocative treatment study by Han et al. looking at the effect of methylphenidate treatment on video game play (Han et al. <xref ref-type="bibr" rid="CR35">2009</xref>). In this study, 62 drug-naïve children with ADHD and Internet addiction were treated with 8 weeks of methylphenidate. Along with reduction in ADHD symptoms, both Internet usage times and scores on Internet addiction tests were shown to decrease over the treatment period.</p><p>In summary, there is a growing body of evidence for an association between problematic Internet and off-line video gaming use and ADHD. While other psychiatric symptoms such as depression and anxiety have also been shown to be associated with Internet addiction (Chak and Leung <xref ref-type="bibr" rid="CR16">2004</xref>; Ryu et al. <xref ref-type="bibr" rid="CR75">2004</xref>; Shapira et al. <xref ref-type="bibr" rid="CR77">2000</xref>), the Ko et al. prospective study shows that ADHD is the strongest predictor (Ko et al. <xref ref-type="bibr" rid="CR50">2009b</xref>). This begs the question, why? What is it about children with ADHD that makes them particularly vulnerable to overuse of the Internet and off-line gaming?</p><p>ADHD youth may have a predisposed vulnerability to the immediacy of feedback as well as the multimodal and high stimulation nature of games. Most games are built so that there is an incentive to “get to the next level,” which has an immediacy that makes it a particularly salient reward incentive to ADHD patients. In addition, rapidly changing screens put minimal demands on attention and working memory (Van De Voorde et al. <xref ref-type="bibr" rid="CR89">2010</xref>), forced effort, or writing (Adi-Japha et al. <xref ref-type="bibr" rid="CR4">2007</xref>) all of which are difficult in ADHD. Individuals with ADHD tend to seek enhanced stimulation of the reward pathway (Volkow et al. <xref ref-type="bibr" rid="CR90">2009</xref>). Video gaming has been shown to increase striatal dopamine release (Koepp et al. <xref ref-type="bibr" rid="CR53">1998</xref>) activating this reward pathway. Further evidence for this hypothesis is found in a study by Han et al., which showed youth with Internet addiction had higher reward dependency and increased prevalence of specific polymorphisms of the dopamine receptor gene implicated in alcoholism and pathologic gambling, when compared with normal controls (Han et al. <xref ref-type="bibr" rid="CR34">2007</xref>). There is no research that has examined whether Internet addiction in youth is associated with increased risk for Internet gambling in adulthood, but assuming that Internet addiction is comparable to other addictions, one might anticipate that childhood exposure may be a gateway to more serious problematic Internet use in adulthood such as pornography or gambling.</p><p>ADHD symptoms and Internet or gaming addiction may share a bidirectional relationship where the symptoms of ADHD make gaming attractive, while gaming itself exacerbates ADHD symptoms by providing an activity that continuously reinforces the exact disinhibition, quick responsiveness, need for immediate reward, and inattention that are areas of concern. In this sense, the prolonged hours of Internet and gaming use may further reinforce and consolidate the child’s proclivity to impulsive, rapid, hyper-focused reactivity. This is also in contrast to the types of activity that might have otherwise filled the same leisure hours such as complex play, sports, music and arts, or organized youth clubs, which would help develop attention, self-control, behavioral inhibition, self-discipline, team skills, and socialization. Even if Internet addiction is not responsible for worsening ADHD symptoms, lack of exposure to these activities might be associated with a decrease in practice opportunities for working memory, patience, attention, and executive functioning (Diamond <xref ref-type="bibr" rid="CR27">2007</xref>; Diamond et al. <xref ref-type="bibr" rid="CR28">2007</xref>). There are then several pathways that might explain the bidirectional association between Internet addiction and ADHD.</p><sec id="Sec3"><title>Risks and benefits of video gaming</title><p>Children may feel proud of the level they have achieved in a particular game. There are now Internet games available in which children can play online with their friends and use a headset to interact by voice while playing. Parents often perceive their child’s perseverative video gaming as a sign of <italic>good</italic> attention and frequently report their children as having higher than average gaming skills. There is, in fact, research that suggests that some forms of computer gaming may build attentional and visual spatial skills (Green and Bavelier <xref ref-type="bibr" rid="CR32">2003</xref>). This raises the question as to whether there may be some skill-building benefit to video gaming in children with ADHD. It is possible that some games will augment reading skills, if reading is required, or fine motor coordination. Computer programs have been developed to improve working memory (Klingberg et al. <xref ref-type="bibr" rid="CR43">2005</xref>), but this does not necessarily apply to recreational games that were not designed for this purpose. In fact, in controlled studies, ADHD is as much an impairment to recreational video gaming as it is to most areas of functioning (Lawrence et al. <xref ref-type="bibr" rid="CR56">2002</xref>, <xref ref-type="bibr" rid="CR57">2004</xref>), with children with ADHD performing more poorly on video games than controls. Thus, parental perception that gaming is what their child does well is likely based more by comparison with their difficulties in many other areas. Other research, however, has demonstrated that children with ADHD, who demonstrated specific problems with impulsive responding on a standardized measure, did not show the same difficulty on a more game-like task, indicating that video games may be a context in which inhibitory performance is consistently reinforced since it is required in most games (Shaw et al. <xref ref-type="bibr" rid="CR79">2005</xref>).</p><p>The risks of Internet use and gaming have been investigated in terms of correlations between use and negative outcomes such as obesity, aggression, and poor school outcome (Mark and Janssen <xref ref-type="bibr" rid="CR61">2008</xref>; Ko et al. <xref ref-type="bibr" rid="CR52">2009d</xref>). The limitation of all such studies is that they are based on correlations and do not establish cause. The children studied are at risk for many of these problems already and so the correlation may reflect an attribute of the population rather than problematic Internet use or games.</p></sec><sec id="Sec4"><title>Treatment for “internet addiction”</title><p>Although excessive use of the Internet and off-line gaming has been demonstrated to be a common, problematic and global problem, the lack of a standardized definition and assessment measures for Internet addiction limits treatment information. As stated in a recent review by Weinstein and colleagues, “Due to the lack of methodologically adequate research, it is currently impossible to recommend any evidence-based treatment of Internet addiction” (Weinstein and Lejoyeux <xref ref-type="bibr" rid="CR92">2010</xref>). There are reports of treatment trials reporting success using many different treatment modalities. Most focus on CBT and CBT groups (Pujol Cda et al. <xref ref-type="bibr" rid="CR74">2009</xref>; Young <xref ref-type="bibr" rid="CR100">2007</xref>), whereas others have looked at a multilevel counseling program (Orzack and Orzack <xref ref-type="bibr" rid="CR71">1999</xref>; Shek et al. <xref ref-type="bibr" rid="CR80">2009</xref>), pharmacotherapy (Dell’Osso et al. <xref ref-type="bibr" rid="CR25">2008</xref>; Han et al. <xref ref-type="bibr" rid="CR35">2009</xref>), empowerment education (Joo and Park <xref ref-type="bibr" rid="CR40">2010</xref>), abstinence (Kalke and Raschke <xref ref-type="bibr" rid="CR41">2004</xref>), and family therapy with ongoing counseling and follow-up along the model of alcoholics anonymous (Orzack and Orzack <xref ref-type="bibr" rid="CR71">1999</xref>). While these reports suggest that Internet addiction may be treatable, we have no research to suggest which treatment is most effective, and no randomized controlled trials to demonstrate that any of these treatments have been effective. Furthermore, we have no guidelines for advising families what risks and benefits typical use carries, or guidelines for how much time should be spent in media that to parents may seem “a waste of time,” but for children reflects the way their peer group relates.</p></sec><sec id="Sec5"><title>Limitations of the literature</title><p>The literature on Internet and off-line video gaming addiction is riddled with methodological problems, several of which have been outlined in recent reviews (Abreu et al. <xref ref-type="bibr" rid="CR3">2008</xref>; Byun et al. <xref ref-type="bibr" rid="CR11">2009</xref>; Weinstein and Lejoyeux <xref ref-type="bibr" rid="CR92">2010</xref>). All of the research described above is based on the use of self-report measures designed for adults and used in youth. This raises a serious concern, since this is something like asking an alcoholic how much he drinks—in any addiction, there is a tendency to minimize the problem.</p><p>There is no current accepted definition for Internet addiction (although many have been proposed (Beard <xref ref-type="bibr" rid="CR8">2005</xref>; Demetrovics et al. <xref ref-type="bibr" rid="CR26">2008</xref>; Fu et al. <xref ref-type="bibr" rid="CR30">2010</xref>; Ko et al. <xref ref-type="bibr" rid="CR45">2005b</xref>, <xref ref-type="bibr" rid="CR51">2009c</xref>; Shaw and Black <xref ref-type="bibr" rid="CR78">2008</xref>; Tao et al. <xref ref-type="bibr" rid="CR87">2010</xref>) making comparison between studies difficult. Different studies focus on different activities, with most focusing exclusively on Internet use, not including off-line computer and gaming station use, which is common in children who tend to do a wide variety of these activities. There is little work on excessive texting, which is now extremely common. With the exception of one prospective study (Ko et al. <xref ref-type="bibr" rid="CR50">2009b</xref>) and the study by Lam and Peng (<xref ref-type="bibr" rid="CR55">2010</xref>) studies are limited to correlations, which do not address causality.</p><p>In addition, terminology varies between studies. Multiple measures have been used to assess Internet and gaming addiction (Beard <xref ref-type="bibr" rid="CR8">2005</xref>; Davis et al. <xref ref-type="bibr" rid="CR24">2002</xref>; Demetrovics et al. <xref ref-type="bibr" rid="CR26">2008</xref>; Johansson and Gotestam <xref ref-type="bibr" rid="CR38">2004</xref>; Khazaal et al. <xref ref-type="bibr" rid="CR42">2008</xref>; Ko et al. <xref ref-type="bibr" rid="CR44">2005a</xref>; Meerkerk et al. <xref ref-type="bibr" rid="CR63">2009</xref>; Nichols and Nicki <xref ref-type="bibr" rid="CR67">2004</xref>; Tejeiro Salguero and Bersabe Moran <xref ref-type="bibr" rid="CR88">2002</xref>). Many of these scales focus exclusively on Internet use. One scale looks exclusively at video gaming (either on or off-line) (Tejeiro Salguero and Bersabe Moran <xref ref-type="bibr" rid="CR88">2002</xref>). Much of the research on Internet addiction has taken place in Asia, and some of the most widely used measures, e.g., the Chen Internet Addiction Scale (Ko et al. <xref ref-type="bibr" rid="CR51">2009c</xref>, <xref ref-type="bibr" rid="CR44">2005a</xref>), are not available in English translation. One of the most widely used English language measures, the Internet Addiction Test (IAT) (Young <xref ref-type="bibr" rid="CR98">1998a</xref>, <xref ref-type="bibr" rid="CR99">b</xref>) has only been validated in adults (Chang and Law <xref ref-type="bibr" rid="CR19">2008</xref>; Widyanto and McMurran <xref ref-type="bibr" rid="CR93">2004</xref>) and includes questions that are inappropriate for children. One validation study included some youth, but mean age of the sample was just over 25 (Widyanto and McMurran <xref ref-type="bibr" rid="CR93">2004</xref>). Furthermore, in developing an Internet and games abuse scale for youth, one would have to be wary of child self-report that might underestimate time spent, such that a parent version would also be needed. Since such a scale has an obvious halo effect, it would be helpful to embed the questions in a more neutral information gathering context.</p><p>Finally, there is little research looking at positive effects of Internet use. For example, a child with selective mutism may be able to “chat.” A child with social phobia may begin the process of meeting people. Even in the area of ADHD, children who are rejected and cannot handle the complexity of social cues may do very well in conversations that rely on a delay and online conversation. Lastly, the obvious potential of these media for teaching has just begun to be explored.</p></sec></sec><sec id="Sec6"><title>Summary</title><p>This review of the literature suggests that there is a correlation between Internet and off-line video gaming use and psychiatric disorders, particularly ADHD. While the condition of “internet addiction” remains controversial (Shaffer et al. <xref ref-type="bibr" rid="CR76">2000</xref>), the consensus of the global literature to date, is that Internet addiction is a disorder in its own right, and that for those who are vulnerable it presents a serious risk with demonstrable impairment and increased psychiatric symptomatology. It remains unclear whether the Internet use itself is the causal factor for increasing psychiatric symptoms and impairment or a simply a reflection of underlying difficulties. We additionally do not yet know whether there is a potential for these media to improve the lives of children, for example by opening up new avenues of learning or increasing opportunities for socialization. However, the evidence presented in this review makes a strong case for a connection between ADHD and Internet, and off-line video gaming use, suggesting that the clinician assessing children with ADHD should routinely inquire about these activities. Stronger conclusions await better definitions of terms such as “internet addiction” and the development of standardized, validated assessment measures for youth. We are in immediate need of systematic research into the etiology of the relationship of computer use and abuse and ADHD, its risks, possible benefits, and treatments. Specifically, future research is required to determine whether there is increased engagement in social and developmentally enriching activities when screen time is decreased; a cohort study of ADHD children versus normal controls for total screen time and further exploration of measurement of the relationship between screen time and functional impairment. We need the answers to the questions every parent is asking.</p><p>Key Points:<list list-type="order"><list-item><p>Recreational electronic activities including Internet use and off-line gaming have
