Brief cognitive assessment in a UK population sample – distributional properties and the relationship between the MMSE and an extended mental state examination

摘要

BackgroundDespite the MMSE's known flaws, it is still used extensively as both a screening instrument for dementia and a population measure of cognitive ability. The aim of this paper is to provide data on the distribution of MMSE scores in a representative sample from the UK population and to compare it with an extended cognitive assessment (EMSE) which covers a wider range of cognitive domains and provides a wider range of difficulty levels.
