Normative data on a battery of neuropsychological tests in the Han Chinese population

In order to develop normative data of a battery of neuropsychological tests in the mainland Chinese population, we examined the performance of 15 neuropsychological tests in 465 healthy subjects (231 males and 234 females) in a population-based cohort study. The years of education were ranged between 1 and 23 years, and ages were ranged between 16 and 75 years old. The 15 neuropsychological tests cover five domains of neurocognitive functions including attention and speed of information processing, memory and learning, verbal function, visual constructive abilities, and executive function. We also assessed the effects of gender, age, educational attainment on the performance of these neuropsychological tests. The results showed that, as expected, educational attainment and age are the two main factors affecting performance in these tests. Educational attainment has the strongest predictive effect on all tests, while the majority of tests selected in this study are also affected by age at examination to varying degrees. The presented normative data will be useful for future studies in related clinical research, and be of value in transcultural neuropsychological studies.
