Racial and ethnic differences in post-stroke subjective cognitive decline exist

Abstract

Background: Racial and ethnic minorities consistently demonstrate disparate post-stroke outcomes. However, there is a paucity of literature related to whether this disparity exists specifically in post-stroke cognitive decline.

Objective: To determine if racial and ethnic disparities exist in post-stroke subjective cognitive decline (SCD) among non-Hispanic Blacks (Blacks), American Indians or Alaska Natives (AI/ANs), Hispanics, and non-Hispanic Whites (Whites) in the United States using data from the Behavioral Risk Factor Surveillance System (BRFSS).

Methods: A retrospective analysis was completed using the 2016 BRFSS data in adults who self-reported stroke and SCD. Descriptive statistics were completed for baseline comparisons using chi squared tests for categorical variables. A binary logistic regression controlling for baseline differences was completed to examine racial and ethnic differences in SCD.

Results: Significant differences in SCD were identified across all racial and ethnic groups. When compared to Whites, Blacks, AI/ANs, and Hispanics more frequently reported worsening confusion or memory loss that interfered with day-to-day activities and the ability to work, volunteer, and engage in social activities outside of the home. AI/ANs who reported SCD were more likely than Whites to have help available. Hispanic persons with SCD or their family members were most likely to discuss SCD with a healthcare provider.

Conclusion: Although persons from all racial and ethnic groups in this study experienced some degree of SCD, Blacks, AI/ANs, and Hispanics most frequently reported worsening confusion or memory loss impacting engagement in day-to-day activities and the ability to work, volunteer, and engage in social activities outside of the home.
