Pediatric bipolar disorder (PBD) is linked to altered brain connectivity in youth. Specifically, PBD affects the anticorrelation between default mode and salience networks during adolescent development.
Area of Science:
- Neuroscience
- Psychiatry
- Developmental Psychology
Background:
- Pediatric bipolar disorder (PBD) is a severe developmental brain disorder in youth.
- Brain connectivity alterations are known in adult bipolar disorder, but less understood in PBD.
Purpose of the Study:
- To investigate functional brain connectivity differences in youths with PBD compared to healthy controls.
- To explore age-related changes in functional connectivity within PBD and control groups.
Main Methods:
- Cross-sectional resting-state functional MRI study.
- Included 32 youths with PBD and 48 healthy controls (HC).
- Compared functional connectivity between intrinsic networks and 333 brain regions.
Main Results:
- Increased inter-network functional connectivity between default mode and salience networks in PBD.
- PBD youth showed a failure to develop age-related anticorrelation in negatively correlated connections.
Conclusions:
- Youth with PBD exhibit reduced anticorrelation between default mode and salience networks.
- Further research is needed to determine if this atypical connectivity is a PBD trait biomarker.
