Screen viewing now begins in infancy with new research finding that the prevalence of screen viewing in children aged under two years ‘is high and appears to increase steadily across age groups’ . Early screen exposure has been facilitated by the advent of infant/toddler products such as the ‘Newborn-to-Toddler Apptivity Seat for iPad ®’ [baby crad...
‘Addiction’ is a term increasingly used to describe the growing number of children engaging in a variety of different screen activities in a dependent, problematic manner. The concept and diagnostic criteria derive from pathological gambling and substance-related addictions and are often based on the amount of time spent engaging in a screen activi...
Prevalence of SDD varies according to the screen activity, the diagnostic tool used, world region, and age of subjects. Studies of 8 – 14 yr. old computer game players in different parts of the world have reported that 8 – 9 % fulfilled diagnostic criteria for ‘pathological video game use’ [25,26]. A recent US study found that among young adolescen...
Various screen activities are reported to induce structural and functional brain plasticity in adults [30,31,32]. However, childhood is a time of significantly greater changes in brain anatomical structure and connectivity . It has been suggested that SDD and even extensive exposure to videogame playing during childhood can lead to neuroadaptation ...
Dopamine is implicated in reward processing and addiction. Hypodopaminergic functioning and a resultant overall reward deficiency characterize SDD. Videogame playing has been associated with dopamine release similar in magnitude to that of drugs of abuse . Nuclear imaging research indicates that SDD is associated with dysfunction of dopaminergic sy...
Individuals with IAD are reported to exhibit reduced dopamine D2 receptor availability in the striatum compared to controls. The greater the severity of IAD, the lower dopamine receptor availability was found to be . Potential presynaptic abnormalities are also observed in subjects with IAD, who exhibit a significantly lower dopamine transporter ex...
Longitudinal studies have found functional changes in the ventral striatum reward system among healthy non-addict-ed subjects engaged in video game training. In contrast to control subjects, those undergoing training exhibited strong activation of the ventral striatum which was maintained for 2 months in response to a non-video game reward task. Th...
Extensive research is increasingly finding that adolescents and young adults with SDD exhibit microstructural and volumetric differences in, or abnormalities of, both grey and white matter compared to healthy controls [50,51,52,53,54 ,55,56,57,58,59]. Differences in brain structure and function are observed in many of the same regions implicated in...
A recent systematic review of fMRI studies involving older adolescents/young IAD adults, without any comorbid psychiatric condition concluded that in the task-related fMRI studies ‘all of them found significant differences in cortical and subcortical brain regions involved in cognitive control and reward processing: Orbitofrontal cortex, insula, an...
Reduced functional connectivity between the ventral tegmental area and nucleus accumbens has been shown in internet gaming addiction as is the case in substance use which is thought to play an important role in the development of substance addiction . The insula has been implicated in salience processing, craving, and interoception, all of which ar...
