Summary
Functional connectome analysis reveals altered brain connectivity in panic disorder (PDO) patients. This study highlights changes in fear networks, suggesting new insights into PDO pathophysiology.
Area of Science:
- Neuroscience
- Psychiatry
- Medical Imaging
Background:
- Functional connectome analysis is an emerging research area for panic disorder (PDO).
- Understanding brain network alterations is crucial for refining the fear network model in PDO pathophysiology.
Purpose of the Study:
- To investigate functional connectome alterations in panic disorder patients.
- To re-evaluate the precision and role of the fear network model in the pathophysiology of panic disorder.
Main Methods:
- Enrolled 53 PDO patients and 54 controls with imaging data.
- Calculated whole-brain functional connectivity matrices.
- Utilized network-based statistics for group comparisons and correlated network measures with illness duration/severity.
Main Results:
- One significant network survived multiple corrections, showing decreased functional connectivity.
- Key affected regions include the left parahippocampal gyrus, bilateral precentral gyri, and others.
- The left parahippocampal gyrus and left precentral gyrus were identified as central hubs.
Conclusions:
- Findings suggest altered functional connectivity in panic disorder patients.
- The involvement of limbic areas and sensory/motor regions may necessitate revisions to the fear network model for PDO.
- This research provides a deeper understanding of the neurobiological underpinnings of panic disorder.
