Prevalence of Mild Cognitive Impairment by Multiple Classifications: The Monongahela-Youghiogheny Healthy Aging Team (MYHAT) Project

The manner in which criteria for MCI are operationalized determines the proportion of individuals who are thus classified and the degree of overlap with other criteria. Prospective follow-up is needed to determine progression from MCI to dementia and thus empirically develop improved MCI criteria with good predictive value.
