Validation of Revised Chinese Version of PD-CRS in Parkinson’s Disease Patients

Figure 1

Comparative progression of impairment of “frontal-subcortical functions” and “instrumental-cortical functions” in PD-NC, PD-MCI, and PDD subgroups (mean ± SE). Cortical functions (confrontation naming and copying a clock) are relatively normal in PD-MCI, but had abrupt decline in the PDD group (a and b). Sustained attention and action verbal fluencies were used as examples to show marked decline of subcortical functions in both PD-MCI and PDD (c and d).
