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.
