Peer-reviewed research shows that Cogmed training provides significant benefits

Listed below are studies of Cogmed Working Memory Training that have been published in peer-reviewed scientific journals since 2002. These include several randomized, double-blind, placebo-controlled trials (Klingberg et. al., 2002 & 2005; Thorell et. al., 2008), studies documenting changes in brain activity following training (Olesen et al., 2004; McNab et al., 2009), and evaluations of Cogmed training by scientists with no affiliation to Cogmed (both papers by Holmes et. al., 2009; Mezzacappa et al., 2010).

The populations studied include youth with ADHD and/or working memory deficits, adult stroke victims, typically developing preschoolers, and healthy adults. The software and protocol used in the studies is the very same as used everyday by the Cogmed network around the world – review our research strategy.

In addition to the published studies shown below, a table summarizing work presented at peer-reviewed scientific meetings along with ongoing studies can be found here.
