Background: Sleep is vital for adolescents’ physical and emotional development; however, sleep disturbances and disorders frequently occur in this age group and affect their health and well-being. In this review, we investigated the prevalence, etiology, diagnosis, clinical characteristics, and treatment of sleep disorders observed among adolescents.Current Concepts: The diagnostic criteria for insomnia disorder among adolescents include difficulties in falling asleep, maintaining sleep, or waking up too early and feeling unrefreshed, which are observed at least 3 days per week over 3 or more months. Cognitive-behavioral therapy for insomnia typically includes identifying and addressing negative thoughts and behaviors associated with sleep and establishing a consistent sleep-wake schedule. Delayed sleep phase syndrome is diagnosed in individuals in whom sleep onset and wake times are persistently delayed by 2 or more hours beyond the desired or existing sleep schedule, which leads to excessive daytime sleepiness or impaired functioning. Behavioral interventions comprise sleep hygiene education, relaxation techniques, and phototherapy. Symptoms such as pronounced snoring, apnea observed by others, and gasping or pauses in breathing during sleep may indicate sleep apnea. Continuous positive airway pressure therapy is an effective treatment strategy for sleep apnea. A history of excessive daytime sleepiness and cataplexy suggests narcolepsy, and treatment options include pharmacotherapy, behavior modification, and lifestyle adjustments. Restless leg syndrome treatments include behavioral therapy, as well as anticonvulsant and dopamine receptor agonist administration.Discussion and Conclusion: Addressing sleep disorders is important to promote optimal health and well-being of adolescents and requires a multidisciplinary approach. Early detection, accurate diagnosis, and individualized treatment improve sleep and overall health outcomes and promote academic and social success.
