Wisconsin Card Sorting Test Variables in Relation to Motor Symptoms in Parkinson's Disease

BackgroundWe recently demonstrated that decline in fluid intelligence is a substantial contributor to frontal deficits. For some classical ‘executive’ tasks, such as the Wisconsin Card Sorting Test (WCST) and Verbal Fluency, frontal deficits were entirely explained by fluid intelligence. However, on a second set of frontal tasks, deficits remained even after statistically controlling for this factor. These tasks included tests of theory of mind and multitasking. As frontal dysfunction is the most frequent cognitive deficit observed in early Parkinson's disease (PD), the present study aimed to determine the role of fluid intelligence in such deficits.MethodWe assessed patients with PD (n=32) and control subjects (n=22) with the aforementioned frontal tests and with a test of fluid intelligence. Group performance was compared and fluid intelligence was introduced as a covariate to determine its role in frontal deficits shown by PD patients.ResultsIn line with our previous results, scores on the WCST and Verbal Fluency were closely linked to fluid intelligence. Significant patient–control differences were eliminated or at least substantially reduced once fluid intelligence was introduced as a covariate. However, for tasks of theory of mind and multitasking, deficits remained even after fluid intelligence was statistically controlled.ConclusionsThe present results suggest that clinical assessment of neuropsychological deficits in PD should include tests of fluid intelligence, together with one or more specific tasks that allow for the assessment of residual frontal deficits associated with theory of mind and multitasking.

Abstract This study aimed to elucidate the role of sex in neurocognitive function in patients with Parkinson’s disease (PD). Ninety-four idiopathic PD and 167 healthy elderly as normal controls (NCs) were recruited and underwent comprehensive neuropsychological assessments. The sex difference were found in NCs but not in PD. In male, PD patients had worse performance on the Digit symbol substitution (DSS) (p < 0.001) and the Symbol Searching (SS) (p < 0.001) than NCs. In female, PD patients had the worse score on the category score of the Modified Wisconsin Card Sorting Test (p < 0.001), the SS (p < 0.001), and the pentagon copying (p < 0.001) than NCs. After controlling age and years of education, Hoehn and Yahr Stage can predict the performance of the Color Trail Test part A (βA = 0.241, pA = 0.036), the Stroop Word-Color Test (β = -0.245, p = 0.036), and the DSS (β = -0.258, p = 0.035) in male PD patients. Sex differences were found in NCs but not in PD. The mental flexibility and visuospatial function are susceptible to female in the PD course. Male PD patients’ working memory and processing speed can be predicted by the disease severity.
