Wenjun Li, B. Douglas Ward, Chunming Xie, Jennifer L. Jones, Piero G. Antuono, Shi-Jiang Li, Joseph S. Goveas
2015 Journal of Psychiatric Research  
However, the overlapping and diverging amygdala network function abnormalities underlying two clinical LLD phenotypes (i.e., LLD alone and LLD with mild cognitive impairment [LLD-MCI]) are unknown.  ...  The amygdala, a crucial hub of the emotional processing neural system, has been implicated in late-life depression (LLD) pathophysiology.  ...  In addition, depression often coexists with mild cognitive impairment (MCI) in the elderly (Bhalla et al., 2009 ).  ...
