Cogmed offers an evidence-based intervention invented by Torkel Klingberg, Ph.D., M.D. and other neuroscientists at the Karolinska Institute in Sweden. Working memory is the cognitive function responsible for keeping information accessible, manipulating it, and using it in thinking and solving problems. Research reveals that individuals with attention problems, such as ADHD, a traumatic brain injury, or even normal aging, have a working memory deficit. This often results in poor academic performance and struggles at work and at home. Delivered to individuals via computer in their own homes, Cogmed Working Memory Training consists of 25 sessions of 30-40 minutes each over a five week period. A Cogmed coach leads the training for each user, tracks their results, and provides them with support.Cogmed Working Memory Training is based on the concept that working memory can be improved with intensive, systematic training. Rigorous scientific research has been conducted and published in leading, peer-reviewed scientific journals, such as Science, Nature Neuroscience and the Journal of the American Academy of Child and Adolescent Psychiatry, demonstrating that Cogmed training is effective. No other brain training product or attention training method has Cogmed's extensive foundation of research validation. This is evidence-based cognitive training.In June 2010, Karolinska Development divested Cogmed to Pearson where it became part of Pearson's Clinical Assessment business. Karolinska Development and other owners will receive an up front payment, as well as tiered royalties up to double digit levels until June 2012 on Cogmed sales. Karolinska Development held 51.83 percent of Cogmed. Pearson will take possession on June 29, 2010.
