Linear regression analysis revealed BMI and morning cortisol after overnight 1 mg dexamethasone (DST) were mostly associated with BDNF (P &amp;lt; .05). No significant difference was found in MoCA scores between MACS and NFAA groups (P = .967), whereas those were lower than the control group (P = .004). When the cognitive subdomains were examined separately, MACS group performed higher memory score than NFAA (P = .045), but lower language scores than both the NFAA (P = .024) and control groups (P &amp;lt; .001). In the whole group, BDNF concentration was positively correlated with memory score (r = 0.337, P = .002), whereas DST was negatively correlated with language score (r = \u22120.355, P =
