Institution: Université Paris Ouest Nanterre La Défense, Université du Québec à Montréal, CMME, Hôpital Sainte-Anne

Program: Cogmed RM

Background & Aim: Fifty to seventy percent of ADHD children will have symptoms that persist into adulthood (Barkley, Murphy, & Fischer, 2008). The estimated prevalence of current adult ADHD is 2,9-4% (Fayyad et al., 2007; Kessler et al., 2006) and adults with ADHD are more likely to exhibit symptoms of inattention than hyperactivity-impulsivity (Blondeau, Rénéric, Martin-Guehl, & Bouvard, 2009). Adults with ADHD may also be more prone to job loss, to have unstable social relationships, to divorce and low-self-esteem (Goodman, 2007). Overall, ADHD significantly affects the quality of life for many individuals (Adler et al., 2006). The primary aim of this research is to investigate the impact of Cogmed Working Memory Training in adults with ADHD on measures of working memory and ADHD symptoms. The secondary objective is to examine the impact of the working memory training (Cogmed) in adults with ADHD on symptoms of anxiety and symptoms of depression.

Population & Sample Size: N = 40 ADHD adults, ages 18- 49 years
• n = 20 adults in adaptive Cogmed training group
• n = 20 adults in non-adaptive (placebo) Cogmed training group

Design: Randomized, placebo controlled, test-retest, 6 month follow-up
