(A) A significant correlation (r=0.86, P<0.001) was found between expression values of the Groningen and original North Shore Parkinson's disease (PD)-related cognitive patterns (PDCPGR and PDCPNS) in the derivation cohort of 19 Groningen PD subjects. (B) A similar correlation (r=0.82, P<0.001) was also present in the prospective group of 86 non-demented PD patients from North Shore, including 20 patients with no cognitive impairment (MCI(−)), as well as 34 with single-domain (MCI(s)) and 32 with multiple-domain (MCI(m)) mild cognitive impairment (MCI).
