To investigate the occurrence and risk factors of mild cognitive impairment (MCI) and the conversion rates to dementia in Chinese people over 80 years of age.
Two hundred and two participants (>80 years old) without dementia were assessed clinically using neuropsychological tests; they were re-assessed at 1, 2, and 3 years.
The results revealed that 30.2% of the study population was classified as having MCI at baseline. Multivariate linear regression analysis showed that coronary heart disease, hypertension, and stroke were risk factors of MCI. During the 3 years follow-up, the occurrence of MCI increased, and 21.8% of the participants with MCI progressed to dementia.
These results suggest that in the older elderly, prevention and early treatment of cardiovascular and cerebrovascular diseases may be effective in lowering the risk of MCI. MCI is a high risk factor for dementia. Copyright © 2011 John Wiley & Sons, Ltd.
