Suivi à long terme des effets d’un entraînement de la mémoire de travail (Cogmed) auprès d’enfants présentant un TDA/H

Abstract

BackgroundAttention-deficit/hyperactivity disorder (ADHD) is a prevalent neurodevelopmental disorder associated with working memory deficits. In that optic, new interventions designed to train working memory have been developed. Cogmed Working Memory Training (CWMT) is a popular online training program that is said to increase working memory (WM) and related skills in the ADHD population. However, follow-up measures are not systematically included, and long-term effects of CWMT are controversial. Also, the number of studies examining transfer of learning and controlling for medication or comorbidities are limited. ObjectivesThis study investigates the long-term effects of CWMT combined with psychostimulant medication on WM and related skills. MethodsThis study included 31 participants aged 7 to 13 years, diagnosed with ADHD (mixed subtype) associated with learning disorders, oppositional-defiant disorder and/or Tourette syndrome. Participants first completed CWMT and were evaluated at follow-up six months later. We used a randomized, double-blind, placebo-controlled design. ResultsThe results found no significant impact of CWMT at follow-up. There were no improvements of WM nor transfer effects on related skills, academic achievement or ADHD symptoms at six months’ follow-up. ConclusionLong-term efficacy of CWMT is not demonstrated. We can’t support CWMT as an effective complementary treatment for children with ADHD and associated comorbidities.
