Study on children with ADHD show that working memory training effects last

New Study Finds Working Memory Training Produces Lasting Improvements in Kids with Attention Deficits

Clinical psychologist uses neuropsychological measures to verify effectiveness of training after six months

Naperville, Ill. and Westlake Village, Ca., Nov. 29, 2007 – Stephen Bozylinski, Ph.D, a clinical psychologist and director of the ADHD Clinic of Southern California, released findings from a new open label study demonstrating the effectiveness of Cogmed Working Memory Training to sustainably improve attention and executive processing in children with ADHD. The study found that significant improvements in working memory, mental stamina, and inhibition and significant decreases in ADHD symptoms remained six to eight months after the training. The research supports and augments previous placebo-controlled and peer reviewed findings from Sweden’s Karolinska Institute that revealed a breakthrough in the way attention problems are understood and treated. Cogmed  is a pioneer in neurotechnology and a developer of software-based working memory training products.

Bozylinski, a Cogmed qualified practitioner, studied 35 ADHD children ranging in age from seven to 17 years, who were trained on the Cogmed Working Memory Training program. The students used video-game software developed by Cogmed to perform verbal and spatial working memory tasks five days a week, for five weeks. Each student was screened positively for ADHD based on a battery of neuropsychological tests. The tests were applied to all 35 children before training and four weeks after training, with more than 90 percent demonstrating significant improvements. The same tests were also applied to 17 of the children six to eight months after training, with 80 percent retaining significant improvements. In addition, parent behavior checklists were also administered with results showing significant improvement in impulsivity, task initiation, working memory, and planning. The children were assessed while off their medication.

“The findings validate that working memory training makes significant and lasting improvements in the lives of students who suffer from attention problems,” said Bozylinski. “This is very promising for a range of people who would otherwise struggle with these debilitating issues for the rest of their lives.”

“We are very proud that Cogmed continues to be the subject of meticulous evaluation and research,” said Jonas Jendi, chief executive officer of Cogmed. “Dr. Bozylinski’s work confirms that working memory training improves a person’s daily life for a long period of time, well beyond the duration of the training.”

Bozylinski presented the results during the CHADD (Children and Adults with Attention Deficit/Hyperactivity Disorder) annual conference in Crystal City, Virginia on November 8th. For more information about the study, please contact Charles Thornton at 630-310-5190 or
