A diet rich in polyphenols — plant-based compounds found in foods like nuts and berries — and online speed-of-processing cognitive training could improve cognition among adults with 12 or fewer years of education. The study, also known as the MINDSpeed trial, recruited 180 participants 60 years of age and older in Marion County, IN. Recipients received a combination of home-delivered snacks and online games using a study-provided tablet and custom app to play. Participants were sorted into four groups: having polyphenol-rich snacks and cognitive training; having polyphenol-rich snacks and control games; having control snacks and cognitive training; and having control snacks and control games. It is feasible to deliver cognitive training and brain healthy snacks to older adults in the community, even to those who are often underserved.”
