The Impact of Adverse Childhood Experiences on Cognition in African American Older Adults: An Integrated Literature Review.

The current integrative literature review examined the existing evidence on the connection between adverse childhood experiences (ACEs) and cognitive changes in African American older adults. Using the Covidence platform, several databases were searched, resulting in 266 publications dated 2008-2020. Ten articles met inclusion criteria and were reviewed. Findings indicate that four ACEs (physical, sexual, and verbal abuse, and low socioeconomic status) are associated with impaired cognition in African American older adults. Four gaps were identified: lack of (a) older adult participants in research investigating original and expanded ACEs; (b) exclusively African American samples of participants in studies examining the relationship between ACEs and cognition; (c) consensus about what specific ACEs contribute to changes in cognition in older adults; and (d) information about successful interventions created to prevent and mitigate the effects of ACEs in older adults. This review provides a synthesis of the limited evidence on the effects of ACEs on cognition among other outcomes. Findings on the effects of ACEs on African American older adults' cognition are limited, thus making a compelling case for further investigating the role of childhood adversity in the disparity of cognitive changes in African American communities.
