Expanded Brain Network Linked to Depression Identified

Researchers find that a larger frontostriatal salience network may increase risk of depression, offering potential for early diagnosis and personalized treatment.

• Study reveals the frontostriatal salience network is significantly larger in people with depression.
• This brain network's size remains stable over time, regardless of mood changes.
• Research suggests the network's expansion could be a risk factor for developing depression.
• Findings are consistent across multiple datasets, including children who later developed depression.
• Potential for using network size as a biomarker to predict and prevent depression.
