With the 25/26 cutoff of the original MoCA, discrepancy further increased to ≤74.3%.Ĭonventional single cutoff scores are associated with substantially high rates of misclassification especially in older and less-educated patients with stroke. Discrepancy increased with higher age and lower education level, with the majority being false positives by single cutoffs. Cognitive health was defined using the Mini-Mental State Examination (score 27/30 points) and the Consortium to Establish a Registry for Alzheimer’s Disease-Neuropsychological Assessment Battery (total score 85.9 points). Using classification with norm-derived cutoff scores as reference, locally derived cutoff score of 21/22 yielded a classification discrepancy of ≤42.4%. Methods: Subjects were recruited from a registry of healthy volunteers. Only 65.1% and 25.7% healthy controls and 45.2% and 19.0% patients scored above the conventional cutoff scores of 21/22 and 25/26 on the MoCA. Sensitivity, specificity and cut-off scores of the MoCA to detect mild cognitive impairment or Alzheimer’s disease and distinguish it from normal aging. Test retest and item by item performance. The norms for the Hong Kong version of the MoCA total and domain scores and the total score of the MoCA 5-minute protocol are described. Consult the latest education and age based norms of the test, average scores for normal, mild cognitive impairment and Alzheimer’s disease. MoCA performance in 919 patients with stroke or transient ischemic attack was classified using the single and norm-derived cutoff scores. Cutoff scores at 16th, 7th, and 2nd percentiles by age and education were derived for the MoCA and MoCA 5-minute Protocol. Using classification with norm-derived cutoff scores as reference, locally derived cutoff score of 21/22 yielded a classification discrepancy of 42.4. magnetic resonance imaging was used to exclude healthy controls with significant brain pathology and medial temporal lobe atrophy. Only 65.1 and 25.7 healthy controls and 45.2 and 19.0 patients scored above the conventional cutoff scores of 21/22 and 25/26 on the MoCA. MoCA norms were collected from 794 functionally independent and stroke- and dementia-free persons aged ≥65 years. The objective of this study is to examine the discrepancy between single versus age and education corrected cutoff scores in classifying performance on the Montreal Cognitive Assessment (MoCA) in patients with stroke or transient ischemic attack. ![]()
