Incident dementia in a defined older Chinese population.

ABSTRACT:

Background

Current knowledge about incident dementia is mainly derived from studies undertaken in the West, showing that dementia is related to older age, low socio-economic status, lack of social network, depression and cardiovascular disease risk factors.
