circadian rhythm sleep disorder, shift work type
MONDO:0024382
A circadian sleep disorder that occurs when work schedules force people to be awake when their circadian rhythms dictate that they should be sleeping. It is classified as a Circadian Rhythm Disorder (CRD) and is extrinsic, i.e. caused by external behavioral factors.
Disease research snapshot
CureCurrent currently links 4 distinct registered clinical trials to circadian rhythm sleep disorder, shift work type through its MONDO disease mappings. 3 of those studies have the registry status “recruiting” (75%). These are registry statuses, not availability guarantees, study results or evidence of effectiveness.
The leading sponsor shown in this linked dataset is First Affiliated Hospital of Zhejiang University, associated with 1 distinct linked trials. This is a count of records, not a ranking of the sponsor's scientific quality.
The highest-count mapped research city in the current result is Adelaide, Australia. Only site locations available in the published registry projection are counted; some trial sites may be missing or outdated.
Numbers are derived from CureCurrent's current ClinicalTrials.gov projection and conservative MONDO/RxNorm mappings. See sources, counting rules and limitations and verify eligibility or clinical findings with the original study record.

Shift work sleep disorder
Shift work sleep disorder (SWSD) is a circadian rhythm sleep disorder characterized by insomnia, excessive sleepiness, or both affecting people whose work hours overlap with the typical sleep period. Insomnia can be the difficulty to fall asleep or waking up before the individual has slept enough. About 20% of the working population participates in shift work. SWSD commonly goes undiagnosed, and it is estimated that 10–40% of shift workers have SWSD. The excessive sleepiness appears when the individual has to be productive, awake and alert. Both symptoms are predominant in SWSD. There are numerous shift work schedules, and they may be permanent, intermittent, or rotating; consequently, the manifestations of SWSD are quite variable. Most people with different schedules than the ordinary one (from 8 AM to 6 PM) might have these symptoms but the difference is that SWSD is continual, long-term, and starts to interfere with the individual's life.
