There is evidence that computerized cognitive training can improve cognition in healthy older adults and in people at risk of developing dementia, although an effective model to implement the training in the daily life of people and to ensure engagement is missing. This project studies the adherence, engagement and progress on computerized cognitive training exercises that were offered by the Association of Retirees from the Telecommunications (ASASTEL) to its associates. One hundred subjects in three different cities (Rio de Janeiro, Belo Horizonte and Brasilia) received licenses to perform the exercises on line and were followed by a team of psychologists. We will evaluate adherence, engagement and progress on the computerized cognitive training exercises of those subjects.
