How loneliness and social surroundings affect the brain and dementia risk
Identifying ADRD intervention targets by characterizing neurobiological mechanisms of social isolation, loneliness, and social environment using novel imaging, molecular markers, and machine learning
Researchers will link loneliness, social isolation, and neighborhood factors to brain changes and dementia risk in adults using brain scans, molecular markers, and machine learning.

What this research studies
This project uses decades of data from the Framingham Study to track how social isolation, loneliness, and your social environment relate to brain biology and dementia risk. Scientists will combine brain imaging, blood and other molecular markers, and advanced machine-learning tools to find biological patterns tied to cognitive decline. The team will relate long-term social exposures across generations to dynamic profiles of Alzheimer's vulnerability. If you are a Framingham participant, your imaging and biospecimens may be analyzed to help map these connections, but the project does not test a new drug or treatment.
Who could benefit from this research
Good fit: Ideal candidates are adults—especially middle-aged and older people—who are part of long-term cohorts like the Framingham Study or who can provide imaging and blood samples alongside detailed social and health information.
Not a fit: People seeking an immediate treatment or cure for dementia are unlikely to receive direct clinical benefit because this is an observational, mechanism-focused project.
Why it matters
Potential benefit: If successful, the findings could point to new ways to prevent or slow Alzheimer’s by targeting social and biological risk pathways.
How similar studies have performed: Previous studies have linked loneliness and isolation to higher dementia risk, but combining large-scale multi-omic data, imaging, and machine learning to map mechanisms is relatively new.
