Circadian Rhythm Sleep Disorders (CRSD) are a group of sleep disorders characterized by a malsynchronization between a person's biological clock and the environmental 24-h schedule. These disorders can lead to harmful psychological and functional difficulties and are often misdiagnosed and incorrectly treated due to the fact that doctors are unaware of their existence. In the following review we describe the characteristics of CRSD, diagnosis, treatment as well as their relationship to… 

Figures from this paper

A circadian rhythm sleep disorder: melatonin resets the biological clock.
TLDR
A patient with a long history of sleep disturbance is diagnosed as having delayed sleep phase syndrome by history and measurement of urinary melatonin metabolite excretion, and the relation of the neurohormone melatonin to circadian rhythm and its other physiological roles are described.
Diagnosis of circadian rhythm sleep disorders.
TLDR
The new international classification of circadian rhythm sleep disorders is reviewed and it is important to keep these two disorders in mind, since they can be confused with insomnia and excessive sleepiness.
A clinical approach to circadian rhythm sleep disorders.
Misdiagnosing sleep disorders as primary psychiatric conditions
Sleep disorders are relevant to psychiatric practice in a number of ways, including the possibility that they may be misdiagnosed as fundamentally psychiatric conditions in patients of all ages. This
The circadian rhythm in adult attention-deficit/hyperactivity disorder: current state of affairs
TLDR
This review focuses on the link between ADHD symptoms and the evening typology through multiple pathways, which involves psychoeducation on sleep hygiene, melatonin in the afternoon or evening and bright light therapy in the morning.
Headache and Sleep: Also Assess Circadian Rhythm Sleep Disorders
TLDR
Evaluation of headache patients for CRSD is especially warranted given the link between mutations in CK1δ (a component of the molecular circadian clock) and migraine, and DLMO is used to determine whether abnormal sleep timing is associated with abnormal circadian rhythm timing (and thus DLMO can confirm the presence of aCRSD).
[Delayed sleep phase type sleep disorder and chronotherapy].
TLDR
A 48-year-old woman is reported that presented with delayed sleep onset and chronotherapy is described as a treatment approach, a behavioral technique in which sleep time is systematically delayed.
A practical approach to circadian rhythm sleep disorders.
SLEEP-WAKE SCHEDULE DISORDER DISABILITY: A LIFELONG UNTREATABLE PATHOLOGY OF THE CIRCADIAN TIME STRUCTURE
TLDR
This work describes two cases of SWSD, the first following head trauma and the second originating during childhood, that had been misdiagnosed by physicians for many years and proposes new medical terminology for such cases—SWSD disability.
Parkinson's disease and sleep.

Clinical characteristics of circadian rhythm sleep disorders
TLDR
Difficulty in adapting to social life was more severe in patients with non‐24 than in those with DSPS, and it was of psychiatric interest that a considerable number of patients had depressive states in the course of their circadian rhythm sleep disorders.
Demography of sleep disturbances associated with circadian rhythm disorders in Japan
To clarify the demography of delayed sleep phase syndrome (DSPS), non‐24‐h sleep–wake syndrome, and irregular sleep–wake pattern in Japan, a cross‐sectional nationwide epidemiological survey was
Circadian Rhythm Sleep Disorders as a Possible Side Effect of Fluvoxamine
TLDR
It is speculated that FVA-induced CRSD is caused by the effect of FVA on serotonin and melatonin levels in the central nervous system, and can be treated by replacing the suspected FVA or adding melatonin to a beneficial FVA treatment.
Delayed sleep phase syndrome. A chronobiological disorder with sleep-onset insomnia.
TLDR
A new syndrome called "delayed sleep phase insomnia" is described, which is proposed to be a disorder of the circadian sleep-wake rhythm in which the "advance" portion of the phase response curve is small.
Circadian rhythm sleep disorders: toward a more precise definition and diagnosis.
TLDR
A survey of the characteristics of patients suffering from circadian rhythm sleep disorders, a case-control study comparing a group of 50 CRSD patients and 56 age- and gender-matched normal subjects, and a proposal for new guidelines for improving the diagnosis of CRSDs are presented.
Posttraumatic delayed sleep phase syndrome
TLDR
Circadian rhythm sleep disorders may occur after traumatic brain injury and delayed sleep phase syndrome was confirmed by sleep logs and actigraphy, which revealed sleep onset in the early morning hours and awakening around noon.
Use of melatonin in the treatment of phase shift and sleep disorders.
TLDR
Both in field and simulated studies of jet lag and shift work suitably timed melatonin improved sleep and, in some cases, hastened readaptation of the circadian rhythms following the phase shift.
SLEEP-WAKE SCHEDULE DISORDER DISABILITY: A LIFELONG UNTREATABLE PATHOLOGY OF THE CIRCADIAN TIME STRUCTURE
TLDR
This work describes two cases of SWSD, the first following head trauma and the second originating during childhood, that had been misdiagnosed by physicians for many years and proposes new medical terminology for such cases—SWSD disability.
Melatonin, sleep, and circadian rhythm disorders.
TLDR
The well-established phase-shifting and sleep-promoting effects of melatonin are documented and some implications for neuropsychiatrists when the neurophysiology ofmelatonin goes array are discussed.
