Shannon entropy: A novel tool for assessing pentagon drawing in Parkinson's disease
Original language description
Objective: We used a digitizing tablet during PCT as a potential tool for assessing early cognitive deficits in PD yet without major cognitive impairment. We also aimed to uncover neural correlates of identified parameter(s) using whole brain MRI. Background: Impaired copy of intersecting pentagons from MMSE (Pentagon Copy Test, PCT) has been shown to predict dementia in PD. Methods: We enrolled 27 PD patients without major cognitive impairment (median age 67.0, median disease duration 4.0.) and 25 age-matched healthy controls (HC) (median age 67.1). During parametrisation of drawing, we focused on the commonly used features and compared both groups using the Mann-Whitney U test. We further focused on parameters with significant correlation with cognitive domains’ z-scores. Selected parameters were used as covariates in the whole brain voxel-wise analysis using 3T MRI and voxel-based morphometry. Results: PD patients differed from HC only in attention domain (p<0.0001).
