Mild cognitive impairment (MCI)
Also known as:
Age-related cognitive decline, Mild neurocognitive disorder, ARCD
Some older people have greater memory and cognitive difficulties than do those undergoing normal aging, but their symptoms are not so severe as to justify a diagnosis of Alzheimer's disease. Some of these people go on to develop Alzheimer's disease; others do not. Authorities have suggested several terms for this middle category, including "mild cognitive impairment"14 and "mild neurocognitive disorder." Risk factors for ARCD include advancing age, female gender, prior heart attack and heart failure.
