The correlation between abnormal functional connectivity values and neuropsychological variables. A The correlation between GDS and dFC between the left anterior hippocampus and the left caudate nucleus (r = 0.182, p = 0.035). B The correlation between GDS and dFC between the right anterior hippocampus and the right caudate nucleus (r = 0.201, p = 0.019). C The correlation between MES and dFC between the left anterior hippocampus and the left caudate nucleus (r = 0.199, p = 0.021). D The correlation between MES and dFC between the right anterior hippocampus and the right caudate nucleus (r = 0.179, p = 0.037). E The correlation between SDMT and dFC between the left anterior hippocampus and left precuneus (r = 0.257, p = 0.003). ∗Statistically significant at the 0.05 level (2-tailed); ∗∗Statistically significant at the 0.01 level (2-tailed); ∗∗Statistically significant at the 0.001 level (2-tailed). LAHP, left anterior hippocampus; LPHP, left posterior hippocampus; RAHP, right anterior hippocampus; RPHP, right posterior hippocampus; HC, healthy controls; SCD, subjective cognitive decline; MES, memory and executive screening; SDMT, Symbol-Digit Modality Test; GDS, Geriatric Depression Scale
