Abstract

ABSTRACT: Objective: African Americans and Latinos/Hispanics have a higher prevalence of dementia compared to non-Latino Whites. This scoping review aims to synthesize non-pharmaceutical interventions to delay or slow age-related cognitive decline among cognitively healthy African American and Latino older adults. Design: A literature search for articles published between January 2000 and May 2019 was performed using the databases PubMed, CINAHL, PsycINFO and Web of Science. Relevant cited references and grey literature were also reviewed. Four independent reviewers evaluated 1, 181 abstracts, and full-article screening was subsequently performed for 145 articles. The scoping review consisted of eight studies, which were evaluated according to the peer-reviewed original manuscript, non-pharmaceutical intervention, cognitive function as an outcome, separate reporting of results for African American and Latinos, minimum age of 40, and conducted in the US. A total of 8 studies were considered eligible and were analyzed in the present scoping review. Results: Eight studies were identified. Four studies focused on African Americans and four focused on Latinos. Through the analysis, results indicated cognitive training-focused interventions were effective in improving memory, executive function, reasoning, visuospatial, psychological function, and speed among African Americans. Exercise interventions were effective in improving cognition among Latinos. Conclusion: This scoping review identified effective non-pharmaceutical interventions among African American and Latinos. Effective interventions focused on cognitive training alone for African Americans and exercise combined with group educational sessions for Latinos. Future research should explore developing culturally appropriate non-pharmaceutical interventions to reduce disparities and to enhance cognition among older African American and Latinos.
