Changes in neighborhood disadvantage over 18 years contributes to racial disparities in later‐life cognition

Neighborhood disadvantage (NDis) is a well‐studied contextual and local indicator of Black‐White health disparities, including cognitive health. Trajectories of NDis are less commonly studied but may be important for understanding how investment and disinvestment in neighborhoods with predominately Black residents may contribute to disparities in cognitive aging. This study characterizes 18‐year trajectories of NDis and examines whether trajectories of NDis mediate Black‐White disparities in cognitive function.
