Study Reveals Brain Network Changes Linked to Depression
A new study published in Nature reveals that depression alters communication patterns in the brain, even when symptoms are absent. Using fMRI technology, researchers discovered an enlarged salience network, crucial for processing stimuli and regulating emotions. This enlargement was observed in both individuals with depression and children who later developed it, suggesting it could be a predictive marker. While the salience network’s remapping may offer insights into depression risk, some scientists caution against viewing it as a universal biomarker, as depression results from the complex interplay of multiple brain circuits. Exercise may help modify the affected brain areas.
