Abstract Objective This study aims to systematically review evidence of the accuracy of the Montreal Cognitive Assessment (MoCA) for evaluating the presence of cognitive impairment in patients with Huntington’s disease (HD) and to outline the quality and quantity of research evidence available about the use of the MoCA in this population. Methods We conducted a systematic literature review, searching four databases from inception until April 2020. Results We identified 26 studies that met the inclusion criteria: two case–control studies comparing the MoCA to a battery of tests, three studies comparing MoCA to Mini-Mental State Examination, two studies estimating the prevalence of cognitive impairment in individuals with HD and 19 studies or clinical trials in which the MoCA was used as an instrument for the cognitive assessment of participants with HD. We found no cross-sectional studies in which participants received the index test (MoCA) and a reference standard diagnostic assessment composed of an extensive neuropsychological battery. The publication period ranged from 2010 to 2020. Conclusions In patients with HD, the MoCA provides information about disturbances in general cognitive function. Even if the MoCA demonstrated good sensitivity and specificity when used at the recommended threshold score of 26, further cross-sectional studies are required to examine the optimum cutoff score for detecting cognitive impairments in patients with HD. Moreover, more studies are necessary to determine whether the MoCA adequately assesses cognitive status in individuals with HD.

Introduction: The Montreal Cognitive Assessment (MoCA) is a cognitive screening test widely used in clinical practice and suited for the detection of Mild Cognitive Impairment (MCI). The aims were to evaluate the psychometric properties of the Persian MoCA as a screening test for mild cognitive dysfunction in Iranian older adults and to assess its accuracy as a screening test for MCI and mild Alzheimer disease (AD). Method: One hundred twenty elderly with a mean age of 73.52 ± 7.46 years participated in this study. Twenty-one subjects had mild AD (MMSE score ≤21), 40 had MCI, and 59 were cognitively healthy controls. All the participants were administered the Mini-Mental State Examination (MMSE) to evaluate their general cognitive status. Also, a battery of comprehensive neuropsychological assessments was administered. Results: The mean score on the Persian version of the MoCA and the MMSE were 19.32 and 25.62 for MCI and 13.71 and 22.14 for AD patients, respectively. Using an optimal cutoff score of 22 the MoCA test detected 86% of MCI subjects, whereas the MMSE with a cutoff score of 26 detected 72% of MCI subjects. In AD patients with a cutoff score of 20, the MoCA had a sensitivity of 94% whereas the MMSE detected 61%. The specificity of the MoCA was 70% and 90% for MCI and AD, respectively. Discussion: The results of this study show that the Persian version of the MoCA is a reliable screening tool for detection of MCI and early stage AD. The MoCA is more sensitive than the MMSE in screening for cognitive impairment, proving it to be superior to MMSE in detecting MCI and mild AD.

Objective: Compare a telephone version and full version of the Montreal Cognitive Assessment (MoCA). Methods: Cross-sectional analysis of a prospective study. A 20-point telephone version of MoCA (Tele-MoCA) was compared to the Full-MoCA and Mini Mental State Examination. Results: Total of 140 participants enrolled. Mean scores for language were significantly lower with Tele-MoCA than with Full-MoCA (P = .003). Mean Tele-MoCA scores were significantly higher for participants with over 12 years of education (P < .001). Cutoff score of 17 for the Tele-MoCA yielded good specificity (82.2%) and negative predictive value (84.4%), while sensitivity was low (18.2%). Conclusions: Remote screening of cognition with a 20-point Tele-MoCA is as specific for defining normal cognition as the Full-MoCA. This study shows that telephone evaluation is adequate for virtual cognitive screening. Our sample did not allow accurate assessment of sensitivity for Tele-MoCA in detecting MCI or dementia. Further studies with representative populations are needed to establish sensitivity.

ABSTRACT:Background:Although cognitive deficits are frequent in multiple sclerosis (MS), screening for them with tools such as the Montreal Cognitive Assessment (MoCA) test is usually not performed unless there is a subjective complaint. The Multiple Sclerosis Neuropsychological Questionnaire (MSNQ) is among the instruments most commonly used to assess self-reported subjective complaints in MS. Nonetheless, it does not always accurately reflect cognitive status; many patients with cognitive deficits thus fail to receive appropriate referral for detailed neuropsychological evaluation. The objective of this study was to examine the validity of the MoCA test to detect the presence of objective cognitive deficits among patients with MS without subjective complaints using the Minimal Assessment of Cognitive Function in MS (MACFIMS) as the gold standard.Methods:The sample included 98 patients who were recruited from a university hospital MS clinic. The MSNQ was used to select patients without subjective cognitive complaints who also completed the MACFIMS, MoCA test and MSQOL-54.Results:23.5% of patients without subjective cognitive complaints had evidence of objective cognitive impairment on the MACFIMS (z score < -1.5 on two or more tests). The MoCA had a sensitivity of 87% and a specificity of 68% for detecting objective cognitive impairment in this patient population using a cut-off score of 27.Conclusion:A significant proportion of patients without self-reported cognitive impairment do have evidence of cognitive deficits on more exhaustive cognitive assessment. The MoCA is a rapid screening test that could be used to target patients for whom a more detailed neuropsychological assessment would be recommended.

Montreal Cognitive Assessment (MoCA) is among the most commonly used screening tools worldwide. Objective: The aim of the study was to provide normative data for the MoCA in a Greek cohort of people older than 60 years who meet criteria for subjective cognitive decline (SCD), mild cognitive impairment (MCI), or dementia in order to optimize cutoff scores for each diagnostic group. Method: Seven hundred forty-six community-dwelling older adults, visitors of the Day Center of Alzheimer Hellas were randomly chosen. Three hundred seventy-nine of them met the criteria for dementia, 245 for MCI and 122 for SCD. Results: Initial statistical analyses showed that the total MoCA score is not affected by gender ( P = .164), or age ( P = .144) but is affected by educational level ( P < .001). A cutoff score of 23 for low educational level (≤6 years) can distinguish people with SCD from MCI (sensitivity 71.4%, specificity 84.2%), while 26 is the cutoff score for middle educational level (7-12 years; sensitivity 73.2%, specificity 67.0%) and high educational level (≥13 years; sensitivity 77.6%, specificity 74.7%). Montreal Cognitive Assessment can discriminate older adults with SCD from dementia, with a cutoff score of 20 for low educational level (sensitivity 100%, specificity 92.3%) and a cutoff score 23 for middle educational level (sensitivity 97.6%, specificity 92.7%) and high educational level (sensitivity 98.5%, specificity 100%). Conclusion: Montreal Cognitive Assessment is not affected by age or gender but is affected by the educational level. The discriminant potential of MoCA between SCD and MCI is good, while the discrimination of SCD from dementia is excellent.

AbstractBackground/Aim Mini mental state examination (MMSE) is a widely accepted tool till date to investigate cognitive status; however, its sensitivity is questioned by few studies. Alternately, Montreal cognitive assessment (MOCA) is considered more effective with high sensitivity to assess cognitive status than MMSE. The usefulness of MOCA is well established in assessing cognitive status in patients in various disorders. Apolipoprotein E (APOE) ɛ4 allele is identified as one of the risk factors associated with cognitive impairment on MMSE; however, the usefulness of MOCA on the association between APOE ɛ4 allele and cognitive impairment is not clearly established and hence the present study.Methods This prospective study recruited 123 subjects diagnosed as tonic-clonic seizures in the study site during the study period.Results Gender and educational status showed normal cognitive function on MMSE but showed cognitive impairment on MOCA. Among epilepsy patients, all APOE ɛ4 carriers showed mild to severe cognitive impairment on MOCA but differences in cognitive status were observed in this population as well as in APOE ɛ4 non-carriers on MMSE.Conclusion Thus, the present study demonstrates the sensitivity of MOCA over MMSE in detecting cognitive impairment in epilepsy.

Background: The involvement of neuropsychiatry is reported in 6% to 91% of Systemic Lupus Erythematosus (SLE) patients. It can cause fatal morbidity and mortality. Memory impairment is one of the most common symptoms of neuropsychiatry involvement. This study aims to find out the performance of memory test in SLE patients using Indonesian version of Montreal Cognitive Assessment (MoCA-Ina).Method: This cross sectional study recruited 30 SLE patients. Cognitive abilities and patient’s memory were examined using Indonesian version of Montreal Cognitive Assessment (MoCA-Ina). Cognitive impairment was determined when total MoCA-Ina score was below 26. For memory evaluation, immediate recall or delayed recall impairment was determined when the patient failed in each memory subtests.Results: The mean of total MoCA-Ina score was 24.97 (SD±3.14). Fifty percent of the SLE patients had cognitive impairment, with the domain involved being delayed recall (86.67%), attention (60%), language (56.67%), abstraction (53.33%), and visuo-spatial/ executive function (36.67%). Most patients (86.67%) could completely repeat immediate recall. Whileonly 4 (13.33%) subjects could repeat delayed recall completely without any clue. Of the 26 SLE patients who failed to recall completely, 24 (92.3%) of them succeeded to recall completely after getting clue(s).Conclusion: Memory impairment is the most frequent cognitive impairment in SLE patients, especially in delayed recall. By using the memory subtests of MoCAIna, more than four fifth of patients with SLE was detected having delayed recall memory impairment and almost all of them could recalled completely after getting clue(s). This findings indicated that the finalstep of memory process retrieval in SLE was interrupted while being encoded, but retention pathway were stillintact.Keywords: Systemic Lupus Erythematous, Memory, MoCA-Ina
