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 MTX 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: MemTrax speed and MemTrax correct. 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. 1045-1054, 2019Ĭognitive impairment is a leading cause of dysfunction in the elderly.
