Late-life depression (LLD) with high prevalence accelerates cognitive impairment and becomes a risk factor for dementia, yet the pathogenesis of LLD is still largely unclear. Delineating the neuromolecular mechanism of LLD is of great significance to its etiology, early diagnosis, and precision treatment. This study included 35 patients with LLD and 41 age-matched healthy controls (HCs). Brain entropy (BEN) and functional connectivity (FC) were used to assess the abnormalities in brain functional system irregularity and couplings in LLD, using resting-state functional magnetic resonance imaging. Additionally, transcriptome and neurotransmitter data were employed to investigate the neuromolecular mechanisms underlying these changes. Compared with HCs, patients with LLD exhibited significantly reduced BEN in the temporoparietal junction (TPJ) and decreased FC between TPJ and the middle frontal gyrus (MFG). Moreover, the changes of BEN were closely associated with the genes’ expression pr
