Abstract and Keywords

Delayed sleep phase disorder (DSPD), common among adolescents, is characterized by an extreme “eveningness” circadian preference. Various etiologies have been proposed for this presumably multifactorial condition. As those afflicted frequently present during a time of transition to earlier school start times, sleep restriction can be profound, which may mediate described associated emotional and mental health difficulties, poor academic performance, and increased risk of unintentional injuries or death. A thorough assessment is required for accurate diagnosis and appropriate treatment. More studies are needed to establish evidence-based clinical guidelines for this young population, particularly as implementation of adult-based therapies are met with numerous barriers.

Keywords: circadian, delayed sleep phase disorder, adolescents, light, melatonin, sleep
