Abstract

Circadian rhythm sleep disorders may affect up to nine different clinical diagnoses.

Common symptoms of insomnia and excessive sleepiness can be associated with circadian rhythm sleep disorders.
These disorders result from a misalignment between sleep patterns and the 24-hour environmental cycle.
Delayed sleep phase is commonly observed in adolescents, while advanced sleep phase is often seen in the elderly.
Blind individuals and those with non-traditional work schedules may have an increased risk of developing these disorders.
A new international classification system for circadian rhythm sleep disorders is presented.

Insomnia and excessive sleepiness are common in the investigation of sleep-disordered breathing. Circadian rhythm sleep disorders are perhaps the most often overlooked conditions in the differential diagnosis of these symptoms. Circadian rhythm sleep disorders manifest as misalignment between the sleep period and the physical/social 24-h environmental cycle. The two most prevalent circadian rhythm sleep disorders are delayed sleep phase (common in adolescents) and advanced sleep phase (common in the elderly), situations in which the sleep period is displaced to a later or earlier time, respectively. It is important to keep these two disorders in mind, since they can be confused with insomnia and excessive sleepiness. However, there are nine possible diagnoses, and all nine are of clinical interest. Since light is the principal cue used in synchronizing the biological clock, blind individuals and night-shift/swing-shift workers are more prone to develop circadian rhythm sleep disorders. In this article, the new international classification of circadian rhythm sleep disorders is reviewed.
