Mild cognitive impairment and cognitive impairment, no dementia: Part A, concept and diagnosis.

Mild cognitive impairment (MCI) and cognitive impairment, no dementia (CIND) are controversial emerging terms that encompass the clinical state between elderly normal cognition and dementia. This article reviews recent work on the classification of MCI and CIND, their prognosis, and diagnostic approaches and presents evidence-based recommendations approved at the meeting of the Third Canadian Consensus Conference on the Diagnosis and Treatment of Dementia (CCCDTD3) held in Montreal in March, 2006. New short tools such as the Montreal Cognitive Assessment are making it easier for family physicians to confidently attach the label of MCI.
