A-E Pearson’s correlation analyses were performed between the functional connectivity of the SMA-IFGorb in the left hemisphere and cognitive performances in MMD patients. The results show that the functional connectivity was significantly correlated with MMSE, MoCA, working memory, and TMT-B. Abbreviations: SMA = supplementary motor area, IFGorb = orbital part of the inferior frontal gyrus, MMSE = Mini–Mental State Examination, MoCA = Montreal Cognitive Assessment, TMT-A/-B = Trail Making Test parts A and B
