The MoCA assesses seven cognitive functions: executive, naming, attention, language, abstraction, memory/delayed recall, and orientation. One of the most frequently used tools for clinical assessment of mild cognitive impairment (MCI) in academic settings is the Montreal Cognitive Assessment (MoCA). To perform clinical assessments of cognitive and behavioral functions of the elderly, clinicians and researchers have developed hundreds of screening and brief assessment tools, and several tests have come into common use.
Therefore, better tools are needed to monitor cognitive function in the elderly. Early detection and identification of cognitive disorders can improve patient care, decrease health care costs, and could help in delaying the onset of more severe symptoms, thus potentially helping to ease the rapidly developing burden of dementia and AD. With increasing age, there is a well-established progressive, exponential increase of the development of cognitive impairment, dementia, and Alzheimer’s disease (AD), which is leading to a huge increase in the number of people with these conditions. The worldwide population, led by Europe, North America, and Northern Asia, is aging, causing a rapid increase in the proportion of elderly persons. These methods showed that for the outcome MemTrax speed a score below the range of 0.87 – 91 s -1 is an indication of MCI, and for the outcome MemTrax correct a score below the range of 85 – 90% is an indication for MCI. Two methods, computing the average MemTrax score and linear regression were used to estimate the cutoff values of the MemTrax test to detect MCI. All MemTrax outcome variables were positively associated with the MoCA. Mean MemTrax scores were significantly lower in the MCI than in the normal cognition group. Based on the results of the MoCA, subjects were divided in two groups of cognitive status: normal cognition ( n = 45) and MCI ( n = 37). Subjects were administered the MoCA and the MemTrax test. Two outcome measures are generated from the MemTrax test: MemTraxspeed and MemTraxcorrect. This study was designed to evaluate the performance of a computerized memory test (MemTrax), which is an adaptation of a continuous recognition task, with respect to the MoCA. However, this test requires a face-to-face administration and is composed of an assortment of questions whose responses are added together by the rater to provide a score whose precise meaning has been controversial. The Montreal Cognitive Assessment (MoCA) is a commonly used tool to screen for MCI. When mild cognitive impairment (MCI) occurs in elderly, it is frequently a prodromal condition to dementia.

For the present, applying a broader and flexible screening procedure in order to detect MCI seems a more useful method than the interpretation of one test result in particular.Authors: van der Hoek, Marjanne D.
However, in this study, insufficient sensitivity and poor specificity were found. The MoCA-D distinguishes between healthy elderly, MCI patients and dementia patients. Specificity for dementia was 81%, PPV 94% and NPV 55%. With a cut-off score of < or = 20, sensitivity to detect dementia in relation to MCI was 100% for severe dementia and 75% for mild dementia. PPV and NPV were 84% and 56%, respectively. With a cutoff score of < or = 25, sensitivity and specificity to detect MCI in relation to healthy controls were 72% and 73%, respectively. Sensitivity, specificity and predictive values (positive: PPV and negative: NPV) of the MoCA-D were assessed.Ī significant effect of group was found on MoCA-D total score (F (2.95) =67.9 p < 0.01). Neuropsychological testing was part of the standard procedure for patients to diagnose MCI. We administered the MoCA-D to healthy control subjects and to elderly with MCI or dementia from a memory disorder outpatient clinic and a geriatric (outpatient) clinic (n = 30, 32, 37 respectively, age > or = 60). Purpose of this study is validating the Dutch version (MoCA-D). The MoCA is a new screening test to detect Mild Cognitive Impairment (MCI).
