Comparison of the Montreal Cognitive Assessment and 7minute Screen Test to Assess Mild Cognitive Impairment Among Geriatric Population

Abstract

Background: Ageing is associated with various cognitive changes which can differ considerably both inter- and intra-individually. Mild cognitive impairment is an intermediate clinical state between normal cognitive ageing and mild cognitive impairment is a precursor to Alzheimer Disease. Screening for Mild Cognitive Impairment is an important aspect when it comes to neurological rehabilitation. TheMoCA and 7MS have shown to be superior to the MMSE in detecting Mild Cognitive Impairment. However there is lack of information on comparison of 7MS withMoCA which could be considered in screening mild cognitive among geriatric patients. Aim of the Study: To compare the 7MS to the MoCA for assessing MCI in a geriatric population. Methods: An Observational Prospective type of study was conducted with sample size of 95 geriatric populations. On day one the MoCA was administered and on day two screening was done using the 7MS. The scores were compared for data analysis. Dataanalysis: Descriptive statistical analysis of total score of the MoCAand 7MS was carried out and results were expressed in terms of mean and standard deviation. Diagnostic test to validate 7MS test for sensitivity and specificity was calculated. Results: The sensitivity of 7MS was found to be 100% but the specificity was only 1.8% compared to the MoCA which has a sensitivity of 100% to a very good to excellent specificity of 87%.Conclusion: The results indicate thatMoCA is a more sensitive and specific tool than the 7MS to assess Mild Cognitive Impairment in a geriatric population.
