  1. Results for Spearman’s correlation analyses between mean FC-st of each main cluster (mθTPA, mδTPA, and mδMVPA) and a series of AD markers (rho and p values) are shown. The list of variables includes the following: working memory (Forward and Reverse Digit Span—forward and reverse digits); episodic memory (Logical Memory II—delayed recall; for units and gist—logical mem. units and gist); anxiety (Goldberg’s test); depression (Geriatric Depression Scale); total gray matter volume (GM, in cubic millimeter); hippocampus, amygdala, and precuneus volumes (left plus right, in cubic millimeter); global fractional anisotropy (FA); and uncinate and parahippocampal fasciculus fractional anisotropy (left and right weighted arithmetic mean). Outcomes that were significant for α < 0.05 and FDR q = 0.1 are bolded
