Official title: Effects of bilingualism in the presence of ADRD risk factors

Funded at University of California, San Francisco · NIH-11223966 · Data updated 2026-11-12

This study is looking at how speaking more than one language might help older adults, especially those at risk for Alzheimer's and similar conditions, keep their brains healthy and strong as they age.

Who could benefit from this research

Could help

Ideal candidates for this research are older adults who are bilingual or monolingual and may be at risk for Alzheimer's disease or related dementias.

Less likely to help

Patients who are not at risk for cognitive decline or who do not speak more than one language may not benefit from this research.

What this research studies

This research investigates the potential protective effects of bilingualism on cognitive health in older adults, particularly those at risk for Alzheimer's disease and related dementias (ADRD). It aims to understand how managing multiple languages may enhance brain function and resilience against cognitive decline. The study will analyze a cohort of both monolingual and bilingual individuals to explore the relationship between language use, executive functioning, and brain health. By examining various sociocultural factors and types of executive functioning tasks, the research seeks to clarify the nuances of bilingualism's impact on aging and dementia.

Why it matters

Potential benefit: If successful, this research could provide insights into how bilingualism may help protect against cognitive decline and improve brain health in aging populations.

How similar studies have gone: Previous research has shown mixed results regarding the cognitive benefits of bilingualism, indicating that this area is still being explored and holds potential for new insights.
