Study Published in Brain Injury Demonstrates Benefits of Cogmed Working Memory Training for Stroke Victims

In January 2007, a team of researchers sponsored by the Karolinska Institute published in Brain Injury the results of a study investigating the rehabilitative affects of working memory training on victims of traumatic brain injury, who often experience attention problems as a result of impaired working memory. The study was conducted in 2005 and led by Helena Westerberg. The results appear in the journal Brain Injury under the title “Computerized working memory training after stroke – A pilot study.”

Eighteen participants suffering from traumatic brain injury and exhibiting working memory problems were randomly assigned to either a control group, or a treatment group performing Cogmed Working Memory Training. Participants in both groups were evaluated before and after the training sessions and also completed a self rating test regarding the symptoms of cognitive failure before and after training.

Participants in the treatment group demonstrated strong improvements in all tasks related to working memory after the training was completed. The self rating test revealed that the treatment group experienced beneficial effects from the training in their daily lives. They reported being less easily distracted when listening to others, less likely to daydream and less likely to lose focus when reading.
