Cogo is a patented, scientifically validated game-based digital therapeutic attention training program that aims to effectively improve children's attention abilities. The technology is based on Brain-Computer Interface (BCI). Researchers have demonstrated, in various clinical trials, Cogo's efficacy. A randomised clinical trial involving 172 children with inattentive tendencies showed significant improvements and is supported by Functional Magnetic Resonance Imaging (fMRI) brain scans, results of which were published in the prestigious journal ""Nature-Translational Psychiatry"". Brain scans showed positive post-training effects observed in areas associated with attention. In a more recent trial using Cogo in home-based settings, clinicians likewise observed overall improvements in 78% of children with #attention problems.
