Abstract
We present 2 cases of delayed sleep phase disorder (DSPD) in adolescents. DSPD is the most frequent circadian rhythm sleep disorder, which often starts in teenage years . However, it frequently goes unrecognized or is misdiagnosed as attention deficit disorder or mood disorder. Incorrect diagnoses lead to inappropriate therapy and persistence of symptoms. DSPD in adolescents often results in a wide range of secondary problems, including school problems (poor school results, concentration problems, absenteeism), behavioral problems, mood swings, and substance abuse.
With this case report, we intend to increase awareness and recognition of this disorder.
