A Neuropsychological Battery for the Evaluation of Dementia Among Mandarin-Speaking Older Adults in the United States.

ABSTRACT

OBJECTIVE: Asians of Chinese origin are the largest single Asian origin group in the United States and are also the third largest group in Harris County, TX (i.e., the Houston metropolitan area). Mandarin speakers constitute the majority of the group. The linguistic gaps between Chinese (Mandarin) and English make it essential to use appropriate tests and normative data when working with the Mandarin-speaking population. Although it is ideal to develop original tests and/or normative data for Mandarin-speaking patients residing in the United States, the process can be lengthy. Although these indigenous tests are being developed, a neuropsychological battery with tests validated in Mandarin-speaking regions (e.g., Mainland China, Taiwan, and Singapore) can provide valuable information for Mandarin-speaking patients who identify with their home culture/country/region. METHODS: A systematic review of two electronic databases (PubMed and PsycInfo) was conducted. RESULTS: A neuropsychological battery to assess cognitive domains, including global intellectual function, attention/processing speed, executive function, visuospatial/visuoconstruction, language, learning and memory, and emotion, was developed. Cognitive screeners and performance validity measures were also included. The battery consists of core and supplementary measures validated in the Mandarin-speaking population. A case illustration is provided. CONCLUSION: Strengths and limitations of the battery and the role of interpretation in service delivery are discussed. The battery is recommended to clinicians for the evaluation of Mandarin-speaking older adults residing in the United States and other non-Mandarin-speaking regions where local norms are not available.
