The social environment and cognitive aging over the life course: laying out critical concepts and research gaps.
Social relationships, work, and neighborhood conditions shape how our brains age and dementia risk—identifying modifiable factors to potentially prevent cognitive decline.
This conceptual review synthesizes the evidence linking social environmental factors—including interpersonal relationships, occupational exposure, and neighborhood characteristics—to cognitive aging outcomes and Alzheimer's disease risk, while laying out critical research gaps needed to establish causal pathways. The framework has direct public health implications given the potential preventability of a significant proportion of dementia cases through modifiable social determinants.

Why it surfaced
Conceptual framework for social determinants of cognitive aging addresses a high-population-burden modifiable risk factor; relevant for AD prevention research agenda and public health policy targeting cognitive decline.
