Understanding how difficult social experiences affect memory and dementia risk in diverse twins

The impact of adverse interpersonal experiences (AIE) on mild cognitive impairment (MCI) and risk for Alzheimer's disease and related dementias (ADRD) in ethnically diverse twins

NIH-funded research University of Minnesota · NIH-11128644

What this research studies

We are exploring how difficult social experiences, like loneliness or conflict, might affect your memory and thinking as you get older. This project builds on an existing study of 800 diverse twin pairs, where we previously gathered information about their social lives. Now, we are adding new tests to check for mild memory problems and using daily diaries to see how everyday social interactions might influence brain function over time. Our goal is to understand how these experiences might increase the risk for conditions like Alzheimer's disease.

Who could benefit from this research

Good fit: Ideal participants are ethnically diverse monozygotic and dizygotic same-sex twin pairs who have previously participated in the Minnesota-Carolina Twin Study of Aging.

Not a fit: Patients who are not part of the existing twin study or who do not meet the age and health criteria for the follow-up assessments may not directly benefit from participation.

Why it matters

Potential benefit: If successful, this work could help us understand how social connections impact brain health, potentially leading to new ways to prevent or delay memory decline and dementia.

How similar studies have performed: Previous studies have shown a link between social experiences and cognitive health, but this project aims to further detail this association with a greater diversity of adverse interpersonal experiences and a daily-level focus.
