Abstract
We report a pilot investigation into the utility of screening tools in Mild Cognitive Impairment (MCI). The Addenbrooke's Cognitive Examination-Revised (ACE-R), Montreal Cognitive Assessment (MoCA) and the novel Computer-Administered Neuropsychological Screen for Mild Cognitive Impairment (CANS-MCI) were administered to 20 elderly controls and 15 MCI cases. Non-parametric Mann–Whitney U-tests showed significant differences between groups (p < .0001) on the CANS-MCI and MoCA. The ACE-R and MoCA total scores showed high sensitivity (90%) to MCI. Area under the curve was consistently significant in discriminating controls and MCI for memory scores across all screening instruments. A useful profile of quantitative and qualitative information pertaining to cognitive functioning in MCI can be obtained with the MoCA, ACE-R, and CANS-MCI.
