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.

Prosopagnosia

Prosopagnosia

Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...

Visual Agnosia

Visual Agnosia

Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round...
