Circadian Rhythm Sleep-Wake Disorders are sleep disorders that involve a change in the timing of when an individual sleeps and is awake. The human body has a master circadian clock in a control centre of the brain known as the suprachiasmatic nucleus (SCN).
A persistent or recurrent pattern of sleep disruption that is primarily due to an alteration of the circadian system or to a misalignment between the endogenous circadian rhythm and the sleep-wake schedule required by an individual’s physical environment or social or professional schedule.
The sleep disruption leads to excessive sleepiness or insomnia, or both.
The sleep disturbance causes clinically significant distress or impairment in social, occupational, and other important areas of functioning.
