Parkinson's disease-related cognitive pattern (PDCP) identified by scaled subprofile model/principal component analysis (SSM/PCA) from a group of 15 non-demented PD patients. PDCP is characterized by bilateral hypometabolism in the supplementary motor area (preSMA), precuneus, the dorsal premotor cortex (PMC), inferior parietal lobule and left prefrontal region and relative increases in the cerebellar vermis and dentate nuclei (DN). Voxels showing metabolic increases are color-coded red and those showing metabolic decreases are color-coded blue. Reprinted with permission from Huang et al. (101).
