Suprachiasmatic nucleus functional connectivity related to insomnia symptoms in adolescents with major depressive disorder

Links

Summary

This study identifies altered functional connectivity between the suprachiasmatic nucleus (SCN) and the precuneus as a potential neural mechanism linking insomnia and depression in adolescents with major depressive disorder. These findings suggest that SCN-targeted interventions, potentially including circadian lighting strategies, could serve as personalized treatment approaches for sleep-related symptoms in depressive youth.

Key Findings

Altered functional connectivity between the SCN and precuneus was associated with insomnia symptoms in adolescents with major depressive disorder.
The SCN-precuneus connectivity disruption was identified as a potential neural biomarker and treatment target for comorbid insomnia and depression in adolescents.
