RESUMEN
Objective To investigate the characteristics of resting-state functional magnetic resonance imaging (fMRI)in patients post-stroke depression (PSD).Methods Resting-state fMRI scans were performed in 13 patients with and without post-stroke depression.A regional homogeneity (ReHo) approach was used as an indicator.The brain function was analyzed in patients with post-stroke depression.Results Compared to a control group,the ReHo values decreased significantly in a PSD group in the left middle frontal gyrus,right superior frontal gyrus,right middle frontal gyrus,right anterior cingulate gyrus,right posterior cingutate gyrus,left insular lobe,left caudate nucleus,and left hippocampus.Conclusions The patients with PSD had restingstate neural circuit dysfunction,suggesting that the need to focus on the emotional state of stroke patients in the clinical treatment process.
