The Intersection of Social Determinants of Health and Post-stroke Aphasia Outcomes: A Need for Intersectional Analysis.

Abstract

Aphasia is a disorder that results from damage to portions of the brain that are responsible for language and can vary significantly by type and severity. Differences in aphasia outcomes are influenced by the social determinants of health (SDOH). The SDOH are structural, environmental, and personal determinants that influence health outcomes. Intersectionality, or how one's social and political identities interact to influence individual life outcomes and/or advantage in our society, provides a way to examine the varying levels of the SDOH. However, intersectionality is complex, difficult to measure, and has not yet been explored in post-stroke aphasia outcomes. This article reviews the relationship of race and aphasia outcomes and the SDOH and aphasia outcomes. Additionally, we provide a novel current approach to examine the SDOH and aphasia outcomes. Lastly, we discuss the need for evaluation of intersectionality in aphasia and aim to provide a leveled social-ecological framework to examine aphasia-related outcomes. With notable individual differences among aphasia outcomes, we present a framework to support optimizing research and clinical aphasia care in speech-language pathology.
