Abstract Background Parkinson’s disease (PD) is a neurodegenerative disorder that causes motor and nonmotor symptoms including cognitive symptoms. This study examines cognition, in particular visuoconstruction with fine motor skills, visuospatial relations and memory. The Vienna Visuoconstructive Test 3.0 (VVT 3.0) using three tasks (VVT3.0 Screening Copy - VVT3.0-SCO, VVT3.0 Screening Delayed Recall - VVT3.0 - SDR, VVT3.0 Screening Quotient - VVT3.0SQU) to test these abilities. The aim of the study was to evaluate the potential of the VVT 3.0 screening by comparing the visuoconstructive abilities of PD patients and control subjects (HC) and examining differences in other neuropsychological tests and sociodemographic characteristics. Material and methods A retrospective study with 287 participants (74 PD, 213 HC) was conducted. Descriptive and inferential statistical analyses were performed. An ROC analysis assessed the discriminatory power of the VVT 3.0 screening scores. Results A significant difference in VVT3.0-SCO was found between the groups (r=0.25). The difference showed a small effect (r=0.23). VVT3.0-SQU showed a large effect (d=0.74). Conclusion The main finding of the present study was that PD leads to a decrease in test performance in VVT3.0-SQU.
