ABSTRACT: Background
Because of the COVID-19 pandemic, the ongoing D-CARE pragmatic trial of two models of dementia care management needed to transition to all data collection by telephone.Methods
For the first 1069 D-CARE participants, we determined the feasibility of administering a short 3-item version of the Montreal Cognitive Assessment (MoCA) to persons with dementia by telephone and examined the correlation with the full 12-item version.Results
The 3-item version could be administered by telephone in approximately 6 min and was highly correlated with the full MoCA (r = 0.78, p < 0.0001).Conclusions
This brief version of the MoCA was feasible to collect by telephone and could be used as an alternative to the full MoCA, particularly if the purpose of cognitive assessment is characterization of study participants.

Project description:OBJECTIVES:While various short variants of the Montreal Cognitive Assessment (MoCA) have been developed, they have not been compared among each other to determine the most optimal variant for routine use. This study evaluated the comparative performance of the short variants in identifying mild cognitive impairment or dementia (MCI/dementia). DESIGN:Baseline data of a cohort study. SETTING:Alzheimer's Disease Centers across the United States. PARTICIPANTS:Participants aged ≥50 years (n = 4606), with median age 70 (interquartile range 65-76). MEASURES:Participants completed MoCA and were evaluated for MCI/dementia. The various short variants of MoCA were compared in their performance in discriminating MCI/dementia, using areas under the receiver operating characteristic curve (AUCs). RESULTS:All 7 short variants of MoCA had acceptable performance in discriminating MCI/dementia from normal cognition (AUC 87.7%-91.0%). However, only 2 variants by Roalf et al (2016) and Wong et al (2015) demonstrated comparable performance (AUC 88.4-88.9%) to the original MoCA (AUC 89.3%). Among the participants with higher education, only the variant by Roalf et al had similar AUC to the original MoCA. At the optimal cut-off score of <25, the original MoCA demonstrated 84.4% sensitivity and 76.4% specificity. In contrast, the short variant by Roalf et al had 87.2% sensitivity and 72.1% specificity at its optimal cut-off score of <13. CONCLUSIONS/IMPLICATIONS:The various short variants may not share similar diagnostic performance, with many limited by ceiling effects among participants with higher education. Only the short variant by Roalf et al was comparable to the original MoCA in identifying MCI or dementia even across education subgroups. This variant is one-third the length of the original MoCA and can be completed in <5 minutes. It provides a viable alternative when it is not feasible to administer the original MoCA in clinical practice and can be especially useful in nonspecialty clinics with large volumes of patients at high risk of cognitive impairment (such as those in primary care, geriatric, and stroke prevention clinics).

Project description:BACKGROUND AND PURPOSE:Face-to-face cognitive testing is not always possible in large studies. Therefore, we assessed the telephone Montreal Cognitive Assessment (T-MoCA: MoCA items not requiring pencil and paper or visual stimulus) and the modified Telephone Interview of Cognitive Status (TICSm) against face-to-face cognitive tests in patients with transient ischemic attack (TIA) or stroke. METHODS:In a population-based study, consecutive community-dwelling patients underwent the MoCA and neuropsychological battery >1 year after TIA or stroke, followed by T-MoCA (22 points) and TICSm (39 points) at least 1 month later. Mild cognitive impairment (MCI) was diagnosed using modified Petersen criteria and the area under the receiver-operating characteristic curve (AUC) determined for T-MoCA and TICSm. RESULTS:Ninety-one nondemented subjects completed neuropsychological testing (mean±SD age, 72.9±11.6 years; 54 males; stroke 49%) and 73 had telephone follow-up. MoCA subtest scores for repetition, abstraction, and verbal fluency were significantly worse (P<0.02) by telephone than during face-to-face testing. Reliability of diagnosis for MCI (AUC) were T-MoCA of 0.75 (95% confidence interval [CI], 0.63-0.87) and TICSm of 0.79 (95% CI, 0.68-0.90) vs face-to-face MoCA of 0.85 (95% CI, 0.76-0.94). Optimal cutoffs were 18 to 19 for T-MoCA and 24 to 25 for TICSm. Reliability of diagnosis for MCI (AUC) was greater when only multi-domain impairment was considered (T-MoCA=0.85; 95% CI, 0.75-0.96 and TICSm=0.83, 95% CI, 0.70-0.96) vs face-to-face MoCA=0.87; 95% CI, 0.76-0.97). CONCLUSIONS:Both T-MoCA and TICSm are feasible and valid telephone tests of cognition after TIA and stroke but perform better in detecting multi-domain vs single-domain impairment. However, T-MoCA is limited in its ability to assess visuoexecutive and complex language tasks compared with face-to-face MoCA.

Project description:The Montreal Cognitive Assessment (MoCA) is one of the most common screening instruments for mild cognitive impairment. However, the standard MoCA is approximately two times longer to administer than the Mini-Mental State Examination. A total of 699 Czech and 175 American participants received the standard MoCA Czech and English versions and in the clinical part, a sample of 102 nondemented patients with Parkinson's disease (PD). We created a validated Czech short version (s-MoCA-CZ) from the original using item response theory. As expected, s-MoCA-CZ scores were highly correlated with the standard version (Pearson r = .94, p < .001). s-MoCA-CZ also had 80% classification accuracy in the differentiation of PD mild cognitive impairment from PD without impairment. The s-MoCA-CZ, a brief screening tool, is shorter to administer than the standard MoCA. It provides high-classification accuracy for PD mild cognitive impairment and is equivalent to that of the standard MoCA-CZ.

Project description:Background: There is a strong need for short and effective methods to screen for cognitive impairment. Recent studies have created short forms of the Montreal Cognitive Assessment (s-MoCA) in English-speaking populations. It is also important to develop a validated Chinese short version to detect cognitive impairment. Methods: Item response theory and computerized adaptive testing analytics were used to construct abbreviated MoCAs across a large neurological sample comprising 6,981 community-dwelling Chinese veterans. Results: Six MoCA items with high discrimination and appropriate difficulty were included in the s-MoCA. The Chinese short versions (sensitivity 0.89/0.90, specificity 0.72/0.77) are similar in performance to the full MoCA in identifying cognitive impairment (sensitivity 0.91, specificity 0.82). Conclusions: These short variants of the MoCA may serve as quick and effective instruments when the original MoCA cannot be feasibly administered in clinical services with a high patient burden and limited cognitive testing resources.

Project description:IntroductionShort forms of the Montreal Cognitive Assessment (MoCA) have allowed quick cognitive screening. However, none of the available short forms has been created or validated in a Swedish sample of patients with stroke.The aim is to develop a short-form Swedish version of the MoCA (s-MoCA-SWE) in a sample of patients with acute and subacute stroke. The specific objectives are: (1) to identify a subgroup of MoCA items that have the potential to form the s-MoCA-SWE; (2) to determine the optimal cut-off value of s-MoCA-SWE for predicting cognitive impairment and (3) and to compare the psychometric properties of s-MoCA-SWE with those of previously developed MoCA short forms.Methods and analysisThis is a statistical analysis protocol for a cross-sectional study. The study sample will comprise patients from Väststroke, a local stroke registry from Gothenburg, Sweden and Efficacy oF Fluoxetine-a randomisEd Controlled Trial in Stroke (EFFECTS), a randomised controlled trial in Sweden. The s-MoCA-SWE will be developed by using exploratory factor analysis and the boosted regression tree algorithm. The cut-off value of s-MoCA-SWE for impaired cognition will be determined based on binary logistic regression analysis. The psychometric properties of s-MoCA-SWE will be compared with those of other MoCA short forms by using cross-tabulation and area under the receiving operating characteristic curve analyses.Ethics and disseminationThe Väststroke study has received ethical approval from the Regional Ethical Review Board in Gothenburg (346-16) and the Swedish Ethical Review Authority (amendment 2019-04299). The handling of data generated within the framework of quality registers does not require written informed consent from patients. The EFFECTS study has received ethical approval from the Stockholm Ethics Committee (2013/1265-31/2 on 30 September 2013). All participants provided written consent. Results will be published in an international, peer-reviewed journal, presented at conferences and communicated to clinical practitioners in local meetings and seminars.

Project description:BackgroundThe Montreal Cognitive Assessment (MoCA) is known to have discriminative power for patients with Mild Cognitive Impairment (MCI). Recently Cognitive Reserve (CR) has been introduced as a factor that compensates cognitive decline. We aimed to assess whether the MoCA reflects CR. Furthermore, we assessed whether there were any differences in the efficacy between the MoCA and the Mini-Mental State Examination (MMSE) in reflecting CR.MethodsMoCA, MMSE, and the Cognitive Reserve Index questionnaire (CRIq) were administered to 221 healthy participants. Normative data and associated factors of the MoCA were identified. Correlation and regression analyses of the MoCA, MMSE and CRIq scores were performed, and the MoCA score was compared with the MMSE score to evaluate the degree to which the MoCA reflected CR.ResultsThe MoCA reflected total CRIq score (CRI; B = 0.076, P < 0.001), CRI-Education (B = 0.066, P < 0.001), and CRI-Working activity (B = 0.025, P = 0.042), while MMSE reflected total CRI (B = 0.044, P < 0.001) and CRI-Education (B = 0.049, P < 0.001) only. The MoCA differed from the MMSE in the reflection of total CRI (Z = 2.30).ConclusionIn this study, we show that the MoCA score reflects CR more sensitively than the MMSE score. Therefore, we suggest that MoCA can be used to assess CR and early cognitive decline.

Project description:OBJECTIVE:Cognitive impairment is common among hemodialysis patient, but still lack adequate screening in clinical settings. The Montreal Cognitive Assessment (MoCA) is reportedly to be a sensitive screening tool for cognitive impairment, but its clinical value in patients undergoing hemodialysis is not well established. We aimed to validate the utility of the Beijing version of the MoCA (MoCA-BJ) for detecting cognitive impairment in comparison to a detailed neuropsychological battery as the gold standard. METHODS:We assessed 613 patients undergoing hemodialysis using the MoCA-BJ, the Mini-Mental State Examination (MMSE), and a comprehensive neuropsychological battery. Cognitive dysfunction was defined by the fifth version of the Diagnostic and Statistical Manual of Mental Disorders (DSM-V). Spearman's correlation and linear regression were used to estimate the performance of the MoCA-BJ and MMSE in predicting cognitive impairment. A receiver operating characteristic (ROC) curve analysis was used to evaluate the utility of various cutoffs of the MoCA-BJ and MMSE for predicting cognitive impairment. RESULTS:Cognitive impairment was diagnosed in 80.91% (496/613), 75.69% (464/613), and 61.34% (376 /613) of the patients using the DSM-V, MoCA-BJ, and MMSE, respectively. Spearman's rank correlation analysis indicated that the MoCA-BJ was significantly correlated with the neuropsychological battery (rs = 0.639, p<0.001), whereas the MMSE had a weaker correlation with the battery. The area under the ROC curve for cognitive impairment diagnosis using the MoCA-BJ was 0.891 (95% confidence interval: 0.859-0.924) while using the MMSE was 0.823 (95% confidence interval: 0.786-0.860). The optimal MoCA-BJ cutoff score in discriminating patients with and without cognitive impairment was 24 points with a sensitivity of 0.877 and specificity of 0.752. CONCLUSION:The MoCA-BJ offers good sensitivity and specificity levels in detecting cognitive impairment in hemodialysis patients. These findings support the utility of the MoCA-BJ as a screening tool for cognitive impairment in Chinese patients undergoing hemodialysis.

Project description:Mild cognitive impairment (MCI) is a common and pivotal non-motor symptom in Parkinson's disease (PD). It is necessary to use the appropriate tools to characterize the cognitive profiles and identify the subjects at risk of MCI in clinical practice. A cohort of 207 non-demented patients with PD and 52 age- and gender-matched cognitively normal controls (NCs) underwent the Chinese Version of Montreal Cognitive Assessment-Basic (MoCA-BC) evaluation. Patients with PD also received detailed motor and non-motor evaluation by serial scales. Cognitive profiles were investigated in patients with PD-MCI, relative to patients with normal cognition (PD-NC) and cognitively NCs. In addition, differences in demography, major motor and non-motor symptoms were compared between patients with PD-MCI and PD-NC. There were 70 patients with PD-MCI, occupying 33.8% of the total patients. Patients with PD-MCI had impairment in multiple cognitive domains, especially in executive function, memory and visuospatial function on MoCA-BC, relative to cognitively NCs or PD-NC. Compared with PD-NC patients, PD-MCI patients were older (p = 0.002) and had a later onset age (p = 0.007) and higher score of the Unified Parkinson's Disease Rating Scale (UPDRS) part III (p = 0.001). The positive rate of clinical possible rapid eye movement sleep behavior disorder (cpRBD) in the PD-MCI group was significantly increased relative to the PD-NC group (p = 0.003). Multivariate logistic analysis showed that older age (OR = 1.06; p = 0.012), higher score of UPDRS-III (OR = 1.03; p = 0.018) and the presence of cpRBD (OR = 2.10; p = 0.037) were independently associated factors of MCI in patients with PD. In conclusion, executive function, memory and visuospatial function are the main impaired cognitive profiles in PD-MCI via MoCA-BC. Aging, motor severity and RBD may be independently related factors of MCI in PD.

Project description:IntroductionPostoperative delirium (POD) affects 10-70% of patients 60 years or older and has been linked to increasing length of hospitalization, mortality, and morbidity. Pre-existing cognitive impairment is a predictor of POD. COVID-19 restricted use of in-person cognitive screens. The Telephone Montreal Cognitive Assessment (T-MoCA) can screen for cognitive dysfunction remotely. We evaluated the feasibility of administering T-MoCA in a multiethnic population during pre-operative testing televisits.MethodsPatients scheduled for surgery between July 2020 and August 2020 were asked to participate in the T-MoCA at the end of their preadmission testing (PAT) televisit. A retrospective chart review was conducted to collect patient comorbidities and demographics. Patients were stratified by negative (T-MoCA≥19) or positive (T-MoCA<19) for mild cognitive impairment (MCI) and compared using 2-tailed χ2-tests. Univariate logistic regression was used to identify associations between patient characteristics and positive T-MoCA result.ResultsFifty out of 65 (77%) patients who consented to the T-MoCA completed the test. The average time to complete the assessment was 10.5 mins. Twenty two (44%) had a negative score and 28 (56%) had a positive score. Patients who had a positive T-MoCA were older (70.04±7.61 yrs) compared to those with a negative T-MoCA (67.68±4.69 yrs, p=0.007), although the distribution of patients above and below age 65 was not different (p=0.243). The two groups did not vary by gender, race/ethnicity, obesity, surgery type, or medical co-morbidities. When we examined our population for predictors of a positive T-MoCA, we found a trend toward men being less likely to score positive on T-MoCA (OR=0.33, 95% CI: 0.10-1.10, p=0.07) compared to women; and that patients with Hispanic race/ethnicity were more likely to test positive on the T-MoCA (OR=4.13, 95% CI: 0.84-20.28, p=0.08) compared to Non-Hispanic Whites.ConclusionsImplementation of the T-MoCA in a telemedicine-based PAT setting is feasible. In our cohort, most people who consented to the assessment completed it, and more than half scored positively, which may have important implications on the surgical plan and post-operative recovery. There may be limitations in using T-MoCA in certain populations, such as non-English preferred language, hearing difficulties, lack of focus, and use of external aids, which would need to be explored in a larger sample size.

Project description:OBJECTIVE:To compare the Short Test of Mental Status (STMS) with the Montreal Cognitive Assessment (MoCA) for predicting and detecting mild cognitive impairment (MCI). PARTICIPANTS AND METHODS:Participants from the community-based Mayo Clinic Study of Aging (MCSA) (November 24, 2010, through May 19, 2012) and an academic referral Alzheimer's Disease Research Center (ADRC) (March 16, 2015, through September 5, 2018) were analyzed. All participants were evaluated using a standardized neuropsychological battery, and a multidisciplinary consensus diagnosis was assigned. The MCSA and ADRC samples included 313 and 106 stable cognitively normal (CN) participants, 72 and 8 CN participants at baseline who developed incident MCI or dementia, 114 and 96 participants with prevalent MCI, and 25 and 132 participants with dementia, respectively. RESULTS:There were no statistically significant differences between the 2 tests in 6 of 7 diagnostic comparisons across academic referral and community populations. The STMS had a better area under the curve (0.90; 95% CI, 0.87-0.93) for differentiating prevalent MCI from CN participants in the MCSA cohort compared with the MoCA cohort (0.85; 95% CI, 0.81-0.89; P=.01). In addition, 53% of the stable CN participants (222 of 419) scored less than 26 on the MoCA, with specificity of 47% for diagnosing prevalent MCI. CONCLUSION:We provide evidence that the STMS performs similarly to the MoCA in a variety of settings and neurodegenerative syndromes. These results suggest that the current recommended MoCA cutoff score may be overly sensitive, consistent with previous studies. We also provide a conversion table for comparing the 2 cognitive tests.
