Mild cognitive impairment (MCI) as pre-dementia syndrome has not been thouroughly studied in underdeveloped regions with cultural and social-economic backgrounds different from Western countries. This study was designed to characterize cognitive profiles of MCI prodromal for vascular dementia (VaD) among an elderly Chinese population.
Moreover, MCI as pre-VaD syndrome has rarely been well studied in underdeveloped regions with cultural and social-economic backgrounds different from Western countries, such as China, in which the social costs for dementia, particularly VaD, may be as sizable as that of developed countries. Recently, reports based on a large, population-based, epidemiological investigations of Chinese elderly has revealed that prevalence of dementia subtypes in China, mainly AD and VaD, is comparable to the prevalence in Western countries
