Mild Cognitive Impairment

Abstract
A GREAT deal of interest has been generated concerning the topic of a boundary or transitional state between normal aging and dementia, or more specifically, Alzheimer disease (AD).1 This condition has received several descriptors including mild cognitive impairment (MCI), incipient dementia, and isolated memory impairment.2-4 Reviews of several studies have indicated that these individuals are at an increased risk for developing AD ranging from 1% to 25% per year.5 The variability in these rates likely reflects differing diagnostic criteria, measurement instruments, and small sample sizes.5
