Recent studies suggest the existence of executive dysfunctions in Mild Cognitive Impairment (MCI). The aim of this work was to verify the presence of executive dysfunctions in patients with MCI. The instruments used were the Wisconsin Card Sorting Test (WCST) and the Iowa Gambling Test (IGT). Ten patients with and 27 without MCI were assessed. The data were analyzed through Student t test for independent samples and analysis of variance (ANOVA) for repeated measures. The results did not show significant difference between groups in the answer rates of WCST and in the number of cards withdrawn from each pack of cards in the IGT. The study of the performance evolution in the IGT revealed a qualitative difference between the groups. Elderly without MCI learn along the task, while elderly with MCI did not, suggesting an interference of memory systems in decision making.Downloads
