Abstract

Cognitive impairment in older adults is a major public concern for Singapore's aging population. The study aimed to (1) examine the effects of age, gender, and education on neuropsychological test performance, and (2) establish regression-based norms in the Singapore older adult (≥ 60 years) population. Data on neuropsychological test performance was extracted from the Well-being of the Singapore Elderly (WiSE) study (n = 2033). Participants who met criteria for dementia were excluded. The data included scores from the 10/66 Dementia Research Group neuropsychological test battery measuring verbal fluency, immediate memory recall, delayed memory recall, and global cognitive function. The General Linear Model (GLM) was used to examine the effects of age, gender, and education on neuropsychological test performance. Stratified weighted means and standard deviations by age, gender and education were reported to establish regression-based normative data. Results from GLM showed that older age and having lower education were associated with poorer performance on all four neuropsychological test measures, and females showed better performance on the tests for immediate memory recall and delayed memory recall. The current study provides useful information on cognitive functioning based on the 10/66 neuropsychological test battery in the older adult population in Singapore. This may help to improve neuropsychological assessments for older adults.
