According to the DSM-5, CRD is a sleep disorder characterized by a discrepancy between the internal setting of one’s circadian clock, and the sleep wake schedule required by one’s occupational/educational or social obligations . The sleep disruption leads to fatigue and/or insomnia.
307.45 (G47.21) Delayed sleep phase type: Delayed onset of sleep and poor maintenance of sleep, with an inability to fall asleep or wake at the desired time (American Psychiatric Association, 2013). This is more commonly seen in adolescents (Martinez, and Lenz, 2010). Other specifiers are: Familial: A family history of delayed onset of sleep. Overlapping with non-24-hour sleep-wake type circadian rhythm disorder.
CRSD (Circadian Rhythm Sleep Disorder) is a DSM-5 (Diagnostic and Statistical Manual of mental Disorders, fifth edition) class of sleep disorders in which one’s internal sleep wake clock is disrupted, resulting in disturbed sleep and consequential daytime fatigue (American Psychiatric Association, 2013).
Onset of Circadian Rhythm Sleep Disorder. The DSM-5 does not specify an age of onset for CRSD. As noted in the diagnostic criteria in the DSM-5, Advanced sleep phase type CRSD typically occurs in older adults. In teens and young adults, Delayed sleep phase type is more common (American Psychiatric Association, 2013).
The DSM-5 does not specify diagnostic rule-outs for CRSD (American Psychiatric Association, 2013). A polysomnograph, or overnight sleep study, should be performed to properly diagnose the type and severity of the sleep disorder.
It is also noted that poor sleep hygiene (e.g., texting or eating in bed, or an irregular bedtime) can contribute to CRSD. A flex-time work schedule, or working swing-shift can lead to CRSD, as can napping during the day, or sleeping past one’s usual rising time.
The DSM-5 does not specify risk factors for the development of CRSD, but the diagnostic subtypes imply there is a genetic link. Having a first order relative with CRSD is a risk factor (American Psychiatric Association, 2013).
