Effect of Cognitive Training Programs Based on Computer Systems on Executive Functions in Children With ADHD: A Systematic Review.

BACKGROUND

The purpose of this systematic review is to synthesize the existing literature reporting the effects of computerized cognitive trainings on the executive functions of children with ADHD.

METHOD

A systematic review was carried out following the PRISMA statement; the primary sources used were five electronic databases (Scopus, Science Direct, Pubmed, Springer, Taylor & Francis).

RESULTS

20 articles met the eligibility criteria, data on the training characteristics and the effects on executive functions were extracted, followed by an analysis of bias and the methodological quality of the studies. The results of the studies were widely heterogeneous, largely associated with the variety of training programs and the measurement instruments used. The most studied executive functions were working memory and inhibitory control. Some of the studies reported that the intervention led to significant effects on working memory and attention (

CONCLUSION

Some training based on computer systems showed positive effects on the executive functions of working memory, attention, and inhibitory control in children with ADHD. However, other training sessions did not show significant effects. In general, the evidence shows mixed results, a high diversity of measurement instruments, and high risks of bias between the studies. Therefore, the evidence has not been consistent about the general benefits of computerized training on the executive functions of children with ADHD.
