• Sleep–wake behavioral characteristics associated with depression symptoms: findings from the Multi-Ethnic Study of Atherosclerosis (2024) · SLEEP · cited 3× · doi

  CONCLUSIONS: These correlative observations suggest that experimental studies are warranted to test if: broadly promoting 24-hour sleep-wake functioning reduces depression even in people without severe insomnia, and if advancing timing leads to depression symptom reductions in people with insomnia.

• 0283 Structural Changes in Visual Cortex and Cognitive Decline During Sleep Deprivation (2025) · SLEEP · doi

  Future studies should examine the reversibility of these structural alterations with recovery sleep and investigate their broader implications for chronic sleep deprivation and associated neurocognitive deficits, potentially identifying novel targets for therapeutic interventions and preventive strategies.

• Association of sleep symptom burden with default mode network homogeneity in first-episode drug-naïve adolescents with major depressive disorder (2026) · Frontiers in Psychiatry · doi

  The relationship between sleep disturbances and major depressive disorder is bidirectional, but the neural mechanisms underlying this relationship are not fully understood. There is a need for studies investigating the association between sleep symptom burden and default mode network homogeneity in adolescents with major depressive disorder.

  Future studies should investigate the longitudinal relationship between sleep disturbances and major depressive disorder. Future studies should explore the neural mechanisms underlying the relationship between sleep disturbances and major depressive disorder. Future studies should develop novel therapeutic strategies targeting sleep disturbances in major depressive disorder.
