Understanding delayed sleep-wake phase disorder (DSWPD): Mechanisms, comorbidities, and evolving approaches to diagnosis and treatment

Key Points

• Delayed sleep-wake phase disorder requires a nuanced integration of circadian biology and behaviour, along with psychiatric comorbidities, for effective treatment.
• Findings suggest that an individualized and multidimensional diagnostic model enhances functioning for those affected by DSWPD, potentially leading to better outcomes.
• The analysis emphasizes the importance of understanding the heterogeneous nature of DSWPD, which can manifest alongside various mental health issues.
• Implementing a comprehensive approach could help optimize diagnosis and treatment pathways for individuals experiencing DSWPD.
