ADHD in children: promising digital interventions, but varying effects

Four categories of interventions, two types of outcomes

The review brings together trials of computer-based interventions, serious video games, games combining physical activity and digital technology, and virtual reality. It distinguishes core ADHD symptoms, including inattention, hyperactivity and impulsivity, from cognitive difficulties.

This distinction matters: improvement on a cognitive assessment does not automatically demonstrate an improvement in symptoms or daily functioning. The abstract does not detail the tests used or the changes observed in the children's lives.

The researchers pooled the results using a random-effects model and assessed the trials' risk of bias. However, the excerpt provides neither the total number of participants nor the detailed findings of that assessment.

Serious games and computer-based training stand out

According to the abstract, digital interventions produce statistically significant improvements in symptoms and cognitive difficulties. The symptom findings are mainly attributed to serious games. The cognitive findings primarily concern computer-based interventions and serious games.

This is not enough to identify any one tool as the best choice. The excerpt does not provide effect sizes, their uncertainty intervals or absolute differences between groups. It therefore does not establish whether the gains are modest or large enough to be noticeable in everyday life.

The findings specific to virtual reality and games incorporating physical activity are not detailed in the abstract. Their inclusion in the review does not, on its own, constitute evidence of effectiveness.

Age, duration and the comparator affect the results

Subgroup analyses report stronger effects in children under 10 and for interventions lasting eight weeks or less. These observations do not establish an optimal duration or demonstrate that extending an intervention would reduce its effectiveness.

The results also vary depending on the comparison group and assessment method. Without details of the comparators, it is difficult to know how much of the benefit is specifically attributable to the digital intervention.

The review therefore supports an avenue for research, not a recommendation for any app or game. Nor does the abstract establish whether benefits persist after the intervention.

What we can take away

Serious games and some computer-based interventions appear promising for children with ADHD. However, this synthesis does not allow a specific product to be selected or establish that a measured improvement translates into a lasting benefit in everyday life.
