validation of the montreal cognitive assessment versus mini mental State Examination against hypertension and hypertensive arteriopathy after transient ischemic attack or minor stroke
Stroke, 2014Co-Authors: Alastair J S Webb, Sarah T Pendlebury, Z Mehta, Michela Simoni, Nicola Lovett, Peter M RothwellAbstract:Background and Purpose—Lack of reduced cognitive impairment with blood pressure (BP) lowering in trials may reflect use of the Mini-Mental State Examination (MMSE), which is insensitive to mild cognitive impairment after cerebrovascular events compared with the Montreal Cognitive Assessment. We determined relationships between impairment on MMSE versus Montreal Cognitive Assessment (MoCA) with the major physiological determinant of vascular cognitive impairment: hypertension and hypertensive arteriopathy. Methods—Cognitive impairment in consecutive patients 6 months after transient ischemic attack or minor stroke was defined as significant, mild, or none (MMSE<23, 23–26, ≥27; MoCA<20, 20–24, ≥25) and related to 20 premorbid systolic BP readings, home BP measurement (3 measurements, 3×daily for 1 month), and hypertensive arteriopathy (creatinine, stroke versus transient ischemic attack, leukoaraiosis) by ordinal regression. Results—Of 463 patients, 45% versus 28% had at least mild cognitive impairment on t...

underestimation of cognitive impairment by mini mental State Examination versus the montreal cognitive assessment in patients with transient ischemic attack and stroke a population based study
Stroke, 2010Co-Authors: Sarah T Pendlebury, Z Mehta, Fiona C Cuthbertson, Sarah J V Welch, Peter M RothwellAbstract:Background and Purpose— The Mini-Mental State Examination (MMSE) is insensitive to mild cognitive impairment and executive function. The more recently developed Montreal Cognitive Assessment (MoCA), an alternative, brief 30-point global cognitive screen, might pick up more cognitive abnormalities in patients with cerebrovascular disease. Methods— In a population-based study (Oxford Vascular Study) of transient ischemic attack and stroke, the MMSE and MoCA were administered to consecutive patients at 6-month or 5-year follow-up. Accepted cutoffs of MMSE <27 and MoCA <26 were taken to indicate cognitive impairment. Results— Of 493 patients, 413 (84%) were testable. Untestable patients were older (75.5 versus 69.9 years, P<0.001) and often had dysphasia (24%) or dementia (15%). Although MMSE and MoCA scores were highly correlated (r2=0.80, P<0.001), MMSE scores were skewed toward higher values, whereas MoCA scores were normally distributed: median and interquartile range 28 (26 to 29) and 23 (20 to 26), resp...

concurrent validity of spanish language versions of the mini mental State Examination mental status questionnaire information memory concentration test and orientation memory concentration test alzheimer s disease patients and nondemented elderly com
Journal of The International Neuropsychological Society, 1996Co-Authors: Maribel I Taussig, Wendy J Mack, Victor W HendersonAbstract:One-hundred fifty-eight elderly Spanish-speaking U.S. residents (81 patients diagnosed with Alzheimer's disease and 77 subjects without dementia) were tested with Spanish-language versions of four brief cognitive assessment instruments: the Mini-Mental State Examination (S-MMSE), the Mental Status Questionnaire (S-MSQ), the Information-Memory-Concentration test (S-IMC), and the Orientation-Memory-Concentration test (S-OMC). Within-group performances were highly correlated for all four instruments. All tests distinguished between the demented and nondemented groups, but best discrimination was achieved with the S-IMC, which correctly classified 98% of subjects. This version was also the best predictor of functional disability, as measured by impairments in instrumental activities of daily living. Within the normal comparison group, neither gender nor a subject's monolingual/bilingual status affected test performance. These four Spanish-language cognitive screening tasks may aid in the evaluation of dementia among Spanish-speaking patients.

the montreal cognitive assessment is superior to the mini mental State Examination in detecting patients at higher risk of dementia
International Psychogeriatrics, 2012Co-Authors: Yanhong Dong, Wah Yean Lee, Nur Adilah Basri, Simon L Collinson, Reshma A Merchant, Narayanaswamy Venketasubramanian, Christopher ChenAbstract:Background: To examine the discriminant validity of the Montreal Cognitive Assessment (MoCA) and the Mini-Mental State Examination (MMSE) in detecting patients with cognitive impairment at higher risk for dementia at a memory clinic setting. Methods: Memory clinic patients were administered the MoCA, MMSE, and a comprehensive formal neuropsychological battery. Mild cognitive impairment (MCI) subtypes were dichotomized into two groups: single domain–MCI (sd–MCI) and multiple domain-MCI (md–MCI). Area under the receiver operating characteristic curve (ROC) analysis was used to compare the discriminatory ability of the MoCA and the MMSE. Results: Two hundred thirty patients were recruited, of which 136 (59.1%) were diagnosed with dementia, 61 (26.5%) with MCI, and 33 (14.3%) with no cognitive impairment (NCI). The majority of MCI patients had md–MCI ( n = 36, 59%). The MoCA had significantly larger AUCs than the MMSE in discriminating md–MCI from the lower risk group for incident dementia (NCI and sd–MCI) [MoCA 0.92 (95% CI, 0.86–0.98) vs. MMSE 0.84 (95% CI, 0.75–0.92), p = 0.02). At their optimal cut-off points, the MoCA (19/20) remained superior to the MMSE (23/24) in detecting md–MCI [sensitivity: 0.83 vs. 0.72; specificity: 0.86 vs. 0.83; PPV: 0.79 vs. 0.72; NPV: 0.89 vs. 0.83; correctly classified: 85.1% vs. 78.7%]. Conclusion: The MoCA is superior to the MMSE in the detection of patients with cognitive impairment at higher risk for incident dementia at a memory clinic setting.

the montreal cognitive assessment moca is superior to the mini mental State Examination mmse for the detection of vascular cognitive impairment after acute stroke
Journal of the Neurological Sciences, 2010Co-Authors: Yanhong Dong, Narayanaswamy Venketasubramanian, Vijay K Sharma, Bernard Poonlap Chan, Hock Luen Teoh, Raymond C S Seet, Sophia Tanicala, Yiong Huak Chan, Christopher ChenAbstract:Abstract Background The majority of patient with post-stroke Vascular Cognitive Impairment (VCI) have Vascular Cognitive Impairment No Dementia (VCIND). The Mini-Mental State Examination (MMSE) has been criticized as a poor screening test for VCIND due to insensitivity to visuospatial and executive function impairments. The Montreal Cognitive Assessment (MoCA) was designed to be more sensitive to such deficits and may therefore be a superior screening instrument for VCIND. Methods Stable patients within 14 days of their index stroke without significant physical disability, aphasia, dysarthria, active psychiatric illness or pre-existing dementia were eligible. Cognitive and neurological measures were administered after informed consent. Results 100 patients were recruited. Of the 57 patients with unimpaired MMSE scores, 18 (32%) patients had an impaired MoCA score. By comparison, only 2 out of the 41 (4.9%) patients with unimpaired MoCA scores had impaired MMSE scores. Moreover, MMSE domain subtest scores could not differentiate between groups of differing screening test results, whilst MoCA domain subtest scores (Visuospatial/Executive Function, Attention and Recall) could. Conclusion The MoCA is more sensitive than the MMSE in screening for cognitive impairment after acute stroke. Longitudinal studies are required to establish the prognostic value of MoCA and MMSE evaluation in the acute post-stroke period for cognitive impairment as defined by the standard method of formal neuropsychological evaluation 3–6 months after stroke.
