Nevertheless, in the color-word incongruent test, compared to HC and PD-NC, PD-MCI showed an increasing trend of all the FC measures and the differences in RS l ( p = 0.030), RS r ( p = 0.009), and GE ( p = 0.007) reached statistical significance between the PD-MCI and HC groups, and RS r was the only parameter that differed significantly between the PD-MCI and PD-NC patients ( p = 0.044).
