To preserve mental function in aging adults, we propose developing and promoting a data-driven ecosystem (called Tri-Neuro) that leverages: 1) data-driven interventions; 2) collective feedback; and 3) a social accountability network. The data-driven interventions include a combination of off-the-shelf memory games, quizzes, puzzles, etc. designed to keep seniors engaged with the active use of their mind. Assessment performance will get collected into a database so that tailored interventions are pushed to users based on their performance metrics in specific categories (eg, memory, cognition, etc.). The collective feedback is driven by both users, health care professionals (including health care providers, social workers, psychologists, counselors and others) who have access to this information, and members of the social accountability network. The feedback will help to encourage ongoing participation and also identify potential signs of memory or cognitive impairment. Crowdsourced feedback from users and the accountability network will also help in identifying which available interventions are yielding the most benefit. The social accountability network includes friends, family, and others who wish to support the individual as he/she participates. This network will help to minimize attrition and can also offer inquire further about any potential signs of memory or cognitive impairment. These individuals will also be able to collaborate and discuss the care of their loved ones. They will be able to see how others on the network are designing care plans for their loved ones. The social network with link to existing online support communities and provide access to mental health, social work, and counseling resources.
