Findings from Second Xiangya Hospital of Central South University Provide New Insights into Bipolar Disorders (Treatment-related changes in functional connectivity of anterior cingulate cortex subregions and their genetic associations in...).

This article focuses on recent research from the Second Xiangya Hospital of Central South University in Hunan, People's Republic of China, investigating functional connectivity changes in anterior cingulate cortex (ACC) subregions in patients with bipolar disorder (BD). Using resting-state functional magnetic resonance imaging (rs-fMRI) on 82 BD patients and 88 healthy controls, the study identified abnormal ACC connectivity patterns that partially normalized following pharmacological treatment over three months. The research also linked these connectivity alterations to gene expression related to synaptic signaling and neurodevelopmental pathways. These findings highlight subregion-specific ACC abnormalities in BD and suggest molecular mechanisms underlying treatment-related brain network changes. [Extracted from the article]
