Delayed Sleep-Wake Phase Disorder (DSWPD) is a circadian rhythm sleep disorder characterized by a significant delay in the timing of the major sleep episode relative to the desired or socially acceptable sleep-wake schedule. This disorder often emerges during adolescence and can persist into adulthood, leading to various symptoms that impact daily functioning.

Delayed Sleep-Wake Phase Disorder is characterized by a significant delay in sleep onset and difficulty waking up early, leading to chronic sleep restriction and various daytime impairments. While sleep duration and quality are normal when unrestricted, the disorder often results in excessive daytime sleepiness, cognitive deficits, and mood disturbances. These symptoms can severely impact daily functioning, particularly in academic and work settings. Effective management requires a comprehensive approach, including behavioral, environmental, and possibly pharmacological interventions.
