Key Points

This research aims to explore how racial discrimination affects age-related changes in serum neurofilament light chain levels among African American women.
Examined serum neurofilament light chain levels from midlife to older adulthood.
Focused on African American women to assess the impact of racial discrimination.
Analyzed the relationship between external stressors and increases in serum neurofilament light chain.
Identified that racial discrimination is linked to accelerated increases in serum neurofilament light chain with age.
Suggests that elevated levels of sNfL may indicate greater neurodegeneration risks among affected individuals.

Abstract

These findings suggest that racial discrimination may contribute to the acceleration of age-related changes in sNfL, a biomarker of neurodegeneration. They further indicate that magnitude of increases in sNfL with age may be sensitive to external stressors and so highlight the potential for targeted interventions to mitigate stress-related risks for accelerated sNfL among African American women.
