Validity of the Georgian Montreal Cognitive Assessment for the Screening of Mild Cognitive Impairment and Dementia

Montreal Cognitive Assessment (MoCA) test has been shown to be a reliable tool to detect mild cognitive impairment (MCI), however, no Georgian language version exists. The goal of this study is to determine the validity, reliability, and accuracy of Georgian version of MoCA in the evaluation of amnestic MCI (aMCI) and Alzheimer’s disease (AD). Montreal Cognitive Assessment was translated into Georgian language and was administered to healthy participants (HP) and patients with aMCI and AD. We studied 46 HS, 20 patients with aMCI, and 20 patients with AD. There was significant difference in MoCA scores between HP, patients with aMCI, and patients with AD (P = 0.04). The area under the receiver operating characteristic curve for the aMCI and AD groups by MoCA was 0.88 and 0.95, respectively, compared to 0.43 and 0.67 by Mini-Mental State Examination (MMSE). The Georgian version of MoCA is a valid, reliable, and sensitive screening tool to detect aMCI and AD in Georgian-speaking population and is superior to MMSE.
