The review also reported a cut-off of 27 or 28 points for MMSE to detect mild cognitive impairment (with a low and wide range of sensitivity rates). A systematic review 11 reported that a large body of studies suggested a general cut-off between 23 and 24 or between 24 and 25 to screen for dementia, which could be appropriate for most primary care populations. 11 Clinical significance is considered to be a change in score of 1.4 to 3 points. 9 – 11 The MMSE has a raw score range of 0 to 30 and typically uses a cut-off of scores below 23 to suggest likely cognitive impairment, 12 although the specific cut-off that is recommended varies based on age and education level. 6 – 8Ĭognitive impairment is commonly assessed using screening tools such as the Mini-Mental State Examination (MMSE), the Montreal Cognitive Assessment (MoCA) and the cognitive subscale of the Alzheimer’s Disease Assessment Scale (ADAS-cog). Studies from the United States have reported prevalence ranging from 9.9% to 35.2% among adults aged 70 or older. 5 Published Canadian cohort prevalence rates for mild cognitive impairment are not available. 4 The reported prevalence of mild cognitive impairment varies because of several factors, such as the diagnostic test score (i.e., cut-off) used to define mild cognitive impairment, age at the initial assessment and length of follow-up. 1 The incidence of dementia among Canadian adults aged 65–79 years is population and rises with age (to 2 among those aged 85 or older). 2, 3 Although some people with mild cognitive impairment may be at higher risk of dementia than others with the diagnosis, over time some will remain stable and a few will show improvements in their cognitive abilities. Mild cognitive impairment is noticeable but does not substantially affect daily function, whereas dementia involves cognitive changes that are severe enough to affect daily function. 1Ĭognitive impairment occurs in a continuum, starting with aging-related cognitive decline, transitioning to mild cognitive impairment and ending with dementia. 1 The most common cognitive functions affected by age are memory and perception, which in some cases may have an impact on more complex cognitive functions such as decision-making and language. Older adults may perform as well as younger adults in some or all cognitive domains, and some may even perform better. These changes, however, do not equally affect all cognitive domains or all people. MCI MoCA adults cognitive decline cutoff highly educated neuropsychological tests.As people age, changes to the structure and the function of the brain may result in cognitive decline. Therefore, it is crucial to use the age- and education-related norms for the MoCA in order to avoid misdiagnosis of cognitive decline. Our study demonstrates that the currently used MoCA cutoff is too high even for highly educated, cognitively normal older adults. However, in substantial contrast, all other neuropsychological scores and the MoCA standardized scores were within the normal range and even above in all years. From the second year and forward, the average MoCA total score was below the cutoff of 26/30. Repeated-measures ANOVA for MoCA raw scores yielded significant decline across the years ( P <. Repeated measures analysis of variance (ANOVA) was used to analyze all standardized scores as well as MoCA standardized and raw scores across all years. ![]() The cognitive assessment included MoCA Rey Auditory Verbal Learning Test Rey Osterrieth Complex Figure test Wechsler Adult Intelligence Scale Information and Digit Span Subtest Trail Making Test Verbal Fluency Test and Beck Depression Inventory questionnaire. Twenty-seven participants aged 68 to 83 (mean = 75.07, standard deviation = 4.62), with high education level (mean = 17.14 years, SD = 3.21) underwent cognitive assessment once a year for 5 consecutive years. To identify whether the MoCA cutoff is too stringent for cognitively normal older adults. Although, age and education-related norms have been published, the vast majority of diagnostic clinicians use the MoCA cutoff score to identify patients with cognitive impairment. The Montreal Cognitive Assessment (MoCA) is widely used to evaluate cognitive decline in older individuals.
