Story summary

Researchers have uncovered a potential breakthrough in understanding major depressive disorder (MDD). By examining brain activity through functional MRI, they discovered that reduced regional homogeneity (ReHo) correlates with diminished blood flow in the brain. This finding suggests that ReHo could be a powerful new biomarker for assessing the severity of MDD.
