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 therapeutic 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. 

Extensive Collaboration with the Research Community

The Cogmed method is a result of many years of successful collaboration with the research community. If your research team contacts with an attached IRB (or the equivalent ethics committee body) approval we can evaluate if the study qualifies for a free research license. The evaluation is based on what level of value and uniqueness the study can contribute to the field, in combination with methodological considerations.

published articles

"Cogmed’s research is spectacular. For the amount of time that Cogmed Working Memory Training has been available, the research has blown everybody else away and has really changed what neurologists think about working memory."

Ph.D. specialized in treatment of ADHD

"...the impact has been tremendous from the standpoint of people’s willingness to look at things differently to improve processing information, linear thinking, and memory systems"

M.D. specialised in developmental problems

"Cogmed has been one of the best programs I have come across in my 20 year career. It develops the pivotal and yet often untreated cognitive skill of working memory"
