Mild cognitive impairment (MCI) is viewed as a transitional stage from normal elderly to dementia. MCI has been identified as an at-risk condition, with an annual conversion rate to dementia of 10% to 20%. As the recent remarkable progress in neuroimaging, some patients with Alzheimer's disease and Lewy body disease are able to be diagnosed at MCI stage. MCI represents neuropsychological test performance below age-, sex, and education-adjusted normal ranges. In this talk, we discuss the pattern of cognitive impairment in these representative neurodegenerative dementias at MCI stage.
