What this research studies

You would join a long-term group of older adults who are seen once a year and asked about their relationships, activities, and daily life. Researchers map your personal social network using in-home interviews and combine that information with yearly memory testing, brain scans, and genetic data. The study follows people with mild cognitive impairment, early Alzheimer’s or related dementias, and similar-age people without memory problems to compare outcomes over time. The team uses these combined social and biological measurements to learn how social connection may build mental resilience.

Who could benefit from this research

Good fit: Ideal candidates are adults with mild cognitive impairment or early-stage Alzheimer's disease or related dementias, as well as age-matched adults without cognitive impairment who can complete annual visits.

Not a fit: People with advanced dementia who cannot participate in interviews or regular visits, or individuals unable to travel to the study site, are unlikely to benefit directly from participation.

Why it matters

Potential benefit: If successful, this work could point to practical ways to strengthen social ties that help slow memory decline or improve quality of life for people with early dementia.

How similar studies have performed: Earlier findings from this same program and other research suggest social engagement is linked to better cognition and cognitive reserve, but targeted social interventions are still being tested.
