Cogmed is a cognitive training software program created in the lab of Torkel Klingberg, a neuroscientist at the Karolinska Institute.

Torkel Klingberg was using it to present working memory challenges to people while he studied their brains using fMRI, to try to learn about neuroplasticity.

[1][2] When the studies appeared to show that the challenges improved working memory, Klingberg founded Cogmed in 2001, with financial backing from the Karolinska Institute and venture capitalists.

[16][17] The largest Cogmed study to date(a randomized, controlled trial by independent researchers, including close to 600 typically developing children) found that Cogmed training led to improvements in "geometry skills, reading skills, Raven’s fluid IQ measure, the ability to inhibit prepotent impulses and self-regulation abilities".

[18] The study also found that, "3–4 years after the intervention, the children who received training [had] a roughly 16 percentage points higher probability of entering the academic track in secondary school".
