Background: Over the last decade, Alzheimer's disease research has shifted its focus from finding a pharmaceutical intervention to treat or delay pathological cognitive decline to identifying how multidomain lifestyle interventions may provide a solution to preserving cognitive health and reducing the risk of or delaying Alzheimer's disease. Maintaining a healthy lifestyle that includes lifelong learning, physical activity, a healthy diet, social engagement and support, restorative sleep, effective coping skills to manage stress and depression, and avoidance of toxins and pollutants has demonstrated a protective effect on cognitive function in healthy older adults. Together, these health behaviors make up a brain healthy lifestyle that is theorized to promote cognitive reserve and reinforce the brain in such a way that it can function optimally in spite of the presence of pathology. The purpose of this study was to determine whether adhering to recommended healthy lifestyle practices and brain health-related behaviors, has a stabilizing effect on cognitive decline in older adults diagnosed with mild neurocognitive disorder due to Alzheimer's disease. The investigator specifically examined the relationships between degree of adherence to treatment recommendations and degree of change in verbal memory performance, and degree of adherence to treatment recommendations and degree of involvement of a supporting person (e.g., spouse, family member, or caregiver).Methods: A quantitative, non-experimental correlational research design was used to examine these relationships in a community-dwelling sample of older adults diagnosed with mild neurocognitive disorder due to Alzheimer's disease. Data on degree of adherence and degree of informant involvement were obtained through a treatment adherence survey. Data on change in verbal memory performance were collected from participant results on recurrent administrations of a word list memory test.Results: Test of linearity revealed a negative linear relationship between total adherence scores and change in verbal memory performance scores, such that, greater adherence to multidomain treatment recommendations was associated with less decline in verbal memory score over time. A hierarchical multiple regression analysis revealed that being married and having high household income explained 16% of the change in verbal memory performance, adding adherence to a healthy diet explained an additional 40%, adding daily brain health-related habits explained an additional 13%, and adding adherence to regular physical activity explained an additional 1% of the change in verbal memory performance. Taken together, these predictor variables accounted for 63% of the variance in verbal memory performance from baseline to follow-up test administration. There was no significant relationship found between degree of informant involvement and degree of adherence to treatment recommendations. Conclusion: Adhering to a brain healthy lifestyle is associated with less decline in verbal memory performance in a small sample of older adults with mild neurocognitive disorder due to Alzheimer's disease. Of particular importance, adherence to a brain healthy diet had the greatest impact on preserving their memory and suggests that this could be a primary target for lifestyle intervention in this population.
