ESTEVES, Cristiane Silva et al. Performance of elderly with and without mild cognitive impairment in the WCST-64 test. Est. Inter. Psicol. [online]. 2018, vol.9, n.3, suppl.1, pp. 149-164. ISSN 2236-6407.

Mild Cognitive Impairment (MCI) is a clinical condition which presents greater cognitive loss than expected for their age or education, do not meeting diagnostic criteria for dementia cases. This article compared the performance of elderly in the reduced version of the Wisconsin Card Sorting Test (WCST-64) in a sample of 56 elderly with an without MCI (n=28 per group) matched by age and by education (mean age=68.93; SD=5.06; education mean=13.21; SD=5.06). The instruments applied were: a sociodemographic questionnaire, a battery of neurocognitive tests and functional capacity, and WCST-64. Data were analyzed through descriptive and inferential analyzes. The DCL group had a worse result only in the WCST-64 error score (p = 0.029). The results suggest that the WCST-64 has the potential to distinguish the performance of adults with and without MCI, indicating the possibility of using this instrument as a screening tool and as a support of this population diagnostic process.

Keywords : elderly people; cognition; neuropsychological tests.
