Circadian rhythm disorders among adolescents: assessment and treatment options

Summary Delayed sleep phase disorder (DSPD) — a circadian rhythm sleep disorder — is most commonly seen in adolescents. The differential diagnosis between DSPD and conventional psychophysiological insomnia is important for correct therapeutic intervention. Adolescent DSPD sleep duration is commonly 9 hours or more. Depression may be comorbid with DSPD. DSPD has a negative impact on adolescent academic performance. DSPD treatments include bright light therapy, chronotherapeutic regimens, and administration of melatonin as a chronobiotic (as distinct from a soporific). Attention to non‐photic and extrinsic factors including healthy sleep parameters is also important to enable better sleep and mood outcomes in adolescents.
