A population-based study in community-dwelling elders living in rural Ecuador. Global cortical atrophy (GCA) associates with worse performance in the Montreal Cognitive Assessment (MoCA). 2013 61:2181–5.ĭel Brutto OH, Mera RM, Zambrano M, Soriano F, Lama J. Criterion and convergent validity of the Montreal cognitive assessment with screening and standardized neuropsychological testing. Lam B, Middleton LE, Masellis M, Stuss DT, Harry RD, Kiss A, et al. The Montreal Cognitive Assessment, MoCA: a brief screening tool for mild cognitive impairment. Nasreddine ZS, Phillips NA, Bédirian V, Charbonneau S, Whitehead V, Collin I, et al. The MoCA is freely accessible for clinical and educational purposes ( and is available in 56 languages and dialects. MoCA Memory Index Score is a newly devised score that can help clinicians better predict which patients with MCI are most likely to convert to dementia. A new version of the MoCA called MoCA-Basic (MoCA-B) was developed to fulfill the limitation of the MoCA among the low educated and illiterate population. MoCA was developed in a memory clinic setting and normed in a highly educated population. Executive functions, higher-level language abilities, and complex visuospatial processing can also be mildly impaired in MCI participants of various etiologies and are assessed by the MoCA with more numerous and demanding tasks than the MMSE. MoCA’s memory testing involves more words, fewer learning trials, and a longer delay before recall than the MMSE. There are several features in MoCA’s design that likely explain its superior sensitivity for detecting MCI. MoCA is also sensitive to detect cognitive impairment in cerebrovascular disease and Parkinson’s disease, Huntington’s disease, brain tumors, systemic lupus erythematosus, substance use disorders, idiopathic rapid eye movement sleep behavior disorder, obstructive sleep apnea, risk of falling, rehabilitation outcome, epilepsy, chronic obstructive pulmonary disease and human immunodeficiency virus infection. MoCA’s sensitivity and specificity to detect subjects with MCI due to Alzheimer’s disease and distinguish them from healthy controls are excellent. Its validity has been established to detect mild cognitive impairment in patients with Alzheimer’s disease and other pathologies in cognitively impaired subjects who scored in the normal range on the MMSE. It is a simple 10 min paper and pencil test that assesses multiple cognitive domains including memory, language, executive functions, visuospatial skills, calculation, abstraction, attention, concentration, and orientation. A conversion formulation was MoCA= 5.91-1.61(age)-1.51(years of education) +0.61(RUDAS score) where age <70 years scores 0 and age 70 years or over scores 1, and 6 years of education or lower scores 0 and more than 6 years of education scores 1.Ĭonclusion: The RUDAS and MOCA had a positive correlation, and the conversion table was developed to simplify the smooth transition of the scores in patients with mild NCD.The Montreal Cognitive Assessment (MoCA) is a cognitive screening instrument developed to detect mild cognitive impairment (MCI). The RUDAS-MoCA conversion score was developed where age and educational level were the independent factors associated with those tests. The Pearson correlation coefficient between the tests was 0.4 (p<0.00). Results: A total of156 patients were recruited and mild NCD was identified in 117 patients (75%). Subsequently, geriatricians assessed each patient for mild NCD according to the diagnostic criteria of the Diagnostic and Statistical Manual of Mental Disorders-5. Baseline information was collected, and the MoCA and RUDAS were administered to each patient by a clinical psychologist. Materials and Methods: A cross-sectional study of outpatients aged >60 years of the general geriatric clinic of Ramathibodi hospital, Thailand between February 2020 to March 2021 was conducted. Objective: To demonstrate the correlation and develop conversion scores between the Montreal Cognitive Assessment (MoCA) and Rowland Universal Dementia Assessment Scale (RUDAS) in patients with mild neurocognitive disorder (NCD).
