Employment which requires frequent shift rotation may lead to the development of specific sleep disorders. Delayed sleep phase (DSP) insomnia, a syndrome identified recently, can greatly impair an individual's circadian rhythm-dependent functions; it can occur when shift work disrupts normal sleep-waking schedules. Disorders of excessive daytime sleepiness, such as narcolepsy, occur in some subjects after they have been subjected to frequently rotating shifts. Understanding the problems associated with circadian rhythm disturbances and their interaction with sleep disorders is particularly important in industrial medicine; any clinician whose patients are subjected to frequent shift rotations should consider the effects of disrupted sleep-waking schedules.

We describe a new syndrome called "delayed sleep phase insomnia." Thirty of 450 patients seen for a primary insomniac complaint had the following characteristics: (1) chronic inability to fall asleep at a desired clock time; (2) when not on a strict schedule, the patients have a normal sleep pattern and after a sleep of normal length awaken spontaneously and feel refreshed; and (3) a long history of unsuccessful attempts to treat the problem. These patients were younger than the general insomniac population and as a group did not have a specific psychiatric disorder. Six patients' histories are described in detail, including the successful nonpharmacological chronotherapy regimen (resetting the patients' biological clock by progressive phase delay). Delayed sleep phase insomnia is proposed to be a disorder of the circadian sleep-wake rhythm in which the "advance" portion of the phase response curve is small.

Delayed sleep phase type sleep disorder is a circadian rhythm disorder that results in symptoms of sleep-onset insomnia and difficulty awakening at a desired time. Patients with delayed sleep phase-type sleep disorder can be treated with chronotherapy, light therapy, vitamin B12, or melatonin. Chronotherapy is a behavioral technique in which sleep time is systematically delayed. Herein we report a 48-year-old woman that presented with delayed sleep onset and describe chronotherapy as a treatment approach.

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.

Up to 50% of children will experience a sleep problem. Early identification of sleep problems may prevent negative consequences, such as daytime sleepiness, irritability, behavioral problems, learning difficulties, motor vehicle crashes in teenagers, and poor academic performance. Obstructive sleep apnea occurs in 1% to 5% of children. Polysomnography is needed to diagnose the condition because it may not be detected through history and physical examination alone. Adenotonsillectomy is the primary treatment for most children with obstructive sleep apnea. Parasomnias are common in childhood; sleepwalking, sleep talking, confusional arousals, and sleep terrors tend to occur in the first half of the night, whereas nightmares are more common in the second half of the night. Only 4% of parasomnias will persist past adolescence; thus, the best management is parental reassurance and proper safety measures. Behavioral insomnia of childhood is common and is characterized by a learned inability to fall and/or stay asleep. Management begins with consistent implementation of good sleep hygiene practices, and, in some cases, use of extinction techniques may be appropriate. Delayed sleep phase disorder is most common in adolescence, presenting as difficulty falling asleep and awakening at socially acceptable times. Treatment involves good sleep hygiene and a consistent sleep-wake schedule, with nighttime melatonin and/or morning bright light therapy as needed. Diagnosing restless legs syndrome in children can be difficult; management focuses on trigger avoidance and treatment of iron deficiency, if present.
