Developed by Cogstate, the CBB is a scientifically validated digital tool that enables cognitive function self-checks and consists of four tests evaluating psychomotor function, attention, learning and memory, and working memory. In?the United States,?Europe,?Australia,?New Zealand?and?Canada, the CBB has been adapted as a medical device named "Cognigram^TM" that has achieved marketing authorization by regulators in these jurisdictions and provides informative results for healthcare professionals to support clinical examination to aid in the diagnosis of MCI and dementia.

In its medium-term business plan, EWAY2025, Eisai is aiming to become a "Medico Societal Innovator" (a company that changes society through creating medicines and providing solutions). Eisai is creating next-generation medical remedies focused on the neurology and oncology areas as well as building disease ecosystem platforms, in order to provide environments and solutions including digital solutions for early diagnosis and early treatment. Cogstate aims to make assessment of brain health as simple, common and informative as assessment of blood pressure. Cogstate's technology, which is easy to use and available in over 70 languages, is supported by extensive scientific validation, including more than 600 peer reviewed publications. Cogstate technology has been used extensively in clinical trials, including trials conducted by Eisai. The global agreement between Eisai and Cogstate will allow the two companies to replicate many of the advancements that have already been launched in?Japan, where Eisai has developed and launched a new digital tool using the CBB, named "NouKNOW^TM" (pronounced "NOH-NOH"), a non-medical device for self-assessment of brain performance (brain health). Eisai is currently investigating the possibility of developing a medical device using the CBB in?Japan. In recent years, various research has demonstrated the possibility that decline in brain performance may be mitigated through major readjustments to lifestyle, such as regular exercise and sleep, a well-balanced diet, and social interaction. However, according to a survey by Eisai, the number of people taking correct preventive actions or habitually performing self-checks of cognitive function are few, with disparities ("chasms") existing against the incorporation of these habits into daily lifestyle. As a result of these findings, in?Japan, Eisai is constructing a dementia platform, called "Easiit", with the goal of erasing these chasms. Core to this platform will be the brain-performance self-check tool "NouKNOW" and the "Easiit App" which aims to contribute to the promotion of health practices through data visualization of brain and body health insights. It can be expected that the use of "NouKNOW"?to perform periodic self-assessments of brain performance among the generation currently in their prime working years, along with the use of the "Easiit App" for the adjustment of lifestyle and practice of preventive measures in daily life, will become an opportunity for the creation of better brain and body health. Through this agreement, Eisai and Cogstate will work together for the development of digital tools for simpler self-checks of cognitive function and diagnostic tool development for healthcare professionals to promote greater awareness of brain performance globally, thus contributing to the realization of well-being for all.
