Z-scores of EEG resting-state network (RSN) activities in AD and ADMCI patients, and healthy subjects.

EEG-RSN	RSN activity in AD and ADMCI	RSN activity in Healthy subjects	P-value
Occipital alpha activity	− 0.36 ± 1.0	0.0 ± 1.0	0.020
Visual perception network	− 0.076 ± 1.0	0.0 ± 1.0	NS
Self-referential network	0.29 ± 1.2	0.0 ± 1.0	NS
Memory network	− 0.74 ± 0.89	0.0 ± 1.0	< 0.001
Sensorimotor network	− 0.054 ± 0.92	0.0 ± 1.0	NS

Data are mean ± standard deviation of z-scores of EEG-RSN activities after healthy age-related changes were corrected using linear regression analysis. RSN, resting state network; AD, Alzheimer’s disease; ADMCI, Mild cognitive impairment due to AD; NS, not significant. The differences between age-corrected RSN activities of the patients (90 AD and 11 ADMCI) and 147 healthy subjects were assessed by independent Student’s t-test with Holm correction.
