The primary goals of the research projects within the Li Lab are to improve diagnostic accuracy for Alzheimer's Disease and related dementias (ADRD) in Asian American and other ethnically diverse populations by developing culturally sensitive and linguistically appropriate neuropsychological assessments. The lab aims to identify early biomarkers and cognitive or behavioral indicators of dementia in diverse populations, particularly among older Asian Americans, to facilitate earlier detection and intervention. Additionally, the lab seeks to enhance the understanding of how dementia symptoms manifest and progress in racially and ethnically minoritized groups by creating diagnostic tools that consider cultural nuances. Interventions based on research findings will be developed to meet the unique needs of older Asian Americans and other underserved populations, thereby improving care quality and health outcomes. A comprehensive database of neuropsychological and clinical data from ethnically diverse populations will be built to advance understanding of dementia risk and progression in these groups. The lab also aims to share findings with the global scientific community to contribute to broader research applications and inform policy recommendations regarding dementia diagnosis and treatment in diverse populations.
