The purpose of this study is to examine the effects of modifiable lifestyle factors including
exercise and healthy living on brain health. The investigators will compare 2 types of
interventions, moderate aerobic walking vs. healthy living education, over 6 months to
evaluate changes in brain health, cognition, and physical function in older adults with
cognitive concerns.

cognitive concerns.
Cognitive decline in older adults is a major public health issue. The cost of caring for
older adults with substantial cognitive impairment, like those with Alzheimer's Disease in
the US is approximately $200 billion a year, causing major societal, economic, and caregiving
burden. Despite great advances towards diagnosing these problems, the discovery of effective
treatments has been minimal. Exploring non-pharmacological interventions, such as exercise
and healthy living, have gained momentum. These promising, modifiable lifestyle interventions
have the potential for delaying disease onset and slowing decline in cognition. However, the
therapeutic effect of lifestyle interventions in patients with mild cognitive impairment, a
prime intervention period for treatment, is not well understood. Therefore, in this study,
the investigators will examine brain, body, and cognitive changes in older adults who engage
in moderate-aerobic walking or healthy living education.
