Asian Americans represent the fastest-growing segment of older adults in the United States, yet many encounter persistent linguistic and cultural barriers when seeking care for dementia-related conditions. These challenges can delay diagnosis, limit access to appropriate services, and contribute to disparities in outcomes. For Mandarin-speaking older adults in particular, standard assessment tools—largely designed for English-speaking populations—may fail to capture important nuances in language, cognition, and cultural context.
In response, a research team led by Rutgers Health has collaborated with leading clinicians and scientists from institutions including the National Institute on Aging-funded Rutgers-NYU Resource Center for Alzheimer’s Disease and the Stanford Alzheimer’s Disease Research Center. Their work focuses on addressing gaps in dementia care for older adults from China and Taiwan living in the United States, offering a culturally and linguistically appropriate solution tailored to this population.
Published in Alzheimer’s & Dementia, the study introduces a newly developed suite of neuropsychological assessments specifically designed for Mandarin-speaking older adults. Rather than relying on direct translations of English tests, the researchers created tools grounded in the structural and cultural characteristics of the Chinese language. These assessments consider the non-alphabetical writing system, the frequency and familiarity of characters used in everyday life, and the cultural experiences of individuals before immigration.
The research was conducted through the Chinese Older Adult Study (COAST), which included 208 participants aged 60 to 90 across regions such as New Jersey, New York City, and the San Francisco Bay Area. Participants represented a spectrum of bilingual abilities, allowing researchers to examine how language proficiency might influence test performance. Over six months, the team evaluated the reliability of the new assessments, their equivalence to established English-language tests, and their alignment with recognised domains of memory and cognitive function.
According to William Hu, professor of neurology and chief of Cognitive Neurology at Rutgers Robert Wood Johnson Medical School, traditional translation tools often fall short. He notes that direct translation can overlook critical linguistic and cultural subtleties, resulting in underdiagnosis, clinical misunderstandings, and diminished trust between patients and healthcare providers. The newly validated toolkit represents a significant advance, as it is the first of its kind rigorously tested among older adults from China, Taiwan, and the broader Chinese diaspora.
The findings show that the Mandarin-based assessments demonstrate strong reliability over time, correlate well with English-language benchmarks, and align with emerging blood-based biomarkers for Alzheimer’s disease. Looking ahead, researchers aim to digitise these tools for use on tablets and immersive platforms such as virtual reality, enabling more accessible and standardised testing without requiring Mandarin-speaking clinicians. Further validation in Cantonese and other Chinese dialects is also planned, with the broader goal of improving diagnostic accuracy, expanding clinical trial participation, and ensuring more inclusive approaches to dementia care and research.
