Background:
Few imaging studies investigated frontal dysfunctions in Parkinson's disease.
Objectives:
We investigated relationships between Wisconsin Card Sorting Test (WCST) and brain perfusion in patients with non-demented Parkinson's disease.
Methods:
Patients were divided into two groups according to WCST score: (1) CA (number of category achieved)
Results:
Hypoperfusions of the bilateral posterior cingulate, rostrodorsal prefrontal, and left frontopolar cortices were shown in CA
Conclusion:
Data indicated participations of various regions in task achievement. Careful interpretation of WCST scores is required.
