Investigating the efficacy of Cogmed in children ADHD

Institution: GGZ Meerkanten

Investigator(s): Dr. Meinte Vollema, Nick Damhuis

Program: Cogmed RM

Background & Aim: ADHD is a developmental disorder with a prevalence of 3 to 7 percent. Defining characteristics include hyperactivity, impulsiveness and difficulty retaining attention for a long period of time. Executive functions, particularly working memory (WM) are key deficits in ADHD. Although originally a developmental disorder, ADHD does not necessarily disappear when a patient reaches adulthood and it is estimated that between 4 to 75 percent of the individuals with childhood diagnoses of ADHD retain these symptoms into adulthood. The most effective intervention for ADHD to date is medication such as methylphenidate. However, this type of stimulant medication alone does not have long term effectiveness and is also marked by poor compliance. The aim of the current study is to assess the complementary effect of Cogmed on WM, executive functions and ADHD symptoms in medicated ADHD children.

Population & Sample Size: N =50 children with ADHD (all medicated/Ritalin), ages 7 -14 years

Design: Randomized, Placebo controlled, Double-blinded, Test-retest, 3 month follow-up
