Cogmed Working Memory Training is validated by clinical, neuropsychological tests and published in peer-reviewed scientific papers.

Proven Effect on Working Memory and Attention

Cogmed is a personalized digital training program, designed to improve the brain systems responsible for attention and working memory.

Working memory is closely related to control of attention, and uses, in part, the same regions of the brain. Cogmed training is specifically developed to target these brain regions (1). It is the only digital tool that has been shown to improve attention in everyday life. The improvements are equivalent to two years of normal cognitive development of working memory in children.

Long-lasting Clinical Effect

Many clinical diagnoses are associated with cognitive impairments affecting working memory and attention. Through clinical, peer-reviewed studies, using neuropsychological testing, it has been shown that Cogmed training can significantly reduce these cognitive impairments in individuals (2).

This includes children and adults with ADHD, children who have received cancer treatment, children born prematurely and adults who have suffered a stroke. In many cases, the behavioral improvement remediates the cognitive function into the normal range (3, 4). The effect on the brain’s working memory systems is stronger from Cogmed training than after treatment with methylphenidate. Most importantly, research shows that the effects of Cogmed training are long-lasting (5).

Improves Academic Performance

Working memory is key for academic performance, including in mathematics. In a recent study of 572 typically developing children, randomized to training or teaching as usual, Berger et al. found that one year after Cogmed training, the difference in mathematical performance between the training group and control group was equivalent to 1 year of normal improvement in secondary school (6). This is about twice as large as the improvements seen after reducing the number of students in a classroom. Three years after the Cogmed training, the children in the training group had a 16 % higher chance of getting into the academically more advanced school-track compared to their control-group peers.

"In our practice, we saw student after student go through the Cogmed program and find that they could now better manage their lives."

"I started feeling the benefits pretty quickly. I was staying engaged and focused for much longer in class, my memory was getting sharper, and that kind of brain fog that comes with a concussion was clearing up."

"Coming across this program was really a blessing, because it's hard to find
something that's as scientifically based as Cogmed is."
