Feasibility of lifestyle interventions for cognition in adults with low education.

ABSTRACT:

Introduction

We report the feasibility and cognitive outcomes of a stage 1b randomized trial testing 3 months of home-delivered high polyphenol snacks (e.g., nuts, berries) and online speed of processing training among older adults with 12 or fewer years of education.

Methods

One hundred eighty participants were randomized to polyphenol-rich snacks and online cognitive training, polyphenol snacks and online control games, control snacks and cognitive training, or control snacks and control games. The outcomes were feasibility of recruitment, retention, and adherence (RRA) and change in a cognitive composite score.
