What this trial studies

This observational study aims to assess the prevalence of Alzheimer's Disease and Related Dementias (ADRD) among the Samoan population aged 50 and older. Participants will undergo cognitive assessments to evaluate their cognitive status and will provide blood samples for genetic and plasma biomarker analysis. The study will utilize culturally adapted instruments and the Uniform Data Set from the National Institute on Aging to ensure accurate prevalence data. Additionally, the study will explore factors related to ADRD resilience and vulnerability within this community.

Who should consider this trial

Good fit: Ideal candidates for this study are Samoans aged 50 and older who are community-dwelling and can communicate in English or Samoan.

Not a fit: Patients residing in assisted living or skilled nursing facilities, or those with unstable medical conditions or psychiatric diagnoses, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the prevalence and risk factors of ADRD in the Samoan population, potentially guiding future interventions.

How similar studies have performed: While studies on ADRD prevalence exist, this specific focus on the Samoan population using culturally adapted methods is novel.
