Mild cognitive impairment (MCI) is a diagnosis that reflects an intermediate stage of cognitive impairment that is often, but not always, a transitional phase from cognitive changes in normal aging to those typically found in dementia, [1] especially dementia due to Alzheimer's disease (Alzheimer's dementia).

There are a variety of disabilities affecting cognitive ability.This is a broad concept encompassing various intellectual or cognitive deficits, including intellectual disability (formerly called mental retardation), deficits too mild to properly qualify as intellectual disability, various specific conditions (such as specific learning disability), and problems acquired later in life through ...
The informant interview is to be conducted if further information about the patient's function is required (i.e. cognitive test score 5 to 8). It consists of six questions which can be answered with “yes” (=impairment), “no” (=no impairment), “don’t know” or “N/A”. Each question is worth one point.
Unlike delirium, mild neurocognitive disorders tend to develop slowly and are characterized by a progressive memory loss which may or may not progress to major neurocognitive disorder. [11] Studies have shown that between 5-17% of patients with mild cognitive disorder will progress to major neurocognitive disorder each year.
The Montreal Cognitive Assessment (MoCA) is a widely used screening assessment for detecting cognitive impairment. [1] It was created in 1996 by Ziad Nasreddine in Montreal, Quebec. It was validated in the setting of mild cognitive impairment (MCI), and has subsequently been adopted in numerous other clinical settings. This test consists of 30 ...
[37] [38] People with objective signs of cognitive impairment, but not more severe symptoms, may be diagnosed with mild cognitive impairment (MCI). If memory loss is the predominant symptom of MCI, it is termed amnestic MCI and is frequently seen as a prodromal or early stage of Alzheimer's disease. [ 39 ]
However, the MMSE scores may be used to classify the severity of cognitive impairment or to document serial change in dementia patients. The following four cut-off levels should be employed to classify the severity of cognitive impairment: no cognitive impairment 24–30; mild cognitive impairment 19–23; moderate cognitive impairment 10–18 ...
The Cognitive Abilities Screening Instrument (CASI) is a cognitive test screening for dementia, in monitoring the disease progression, and in providing profiles of cognitive impairment by examining abilities on attention, concentration, orientation, short-term memory, long-term memory, language abilities, visual construction, list-generating fluency, abstraction, and judgment with score ranges ...
