Thus, sleep-wake cycle disruption (7/19 subjects) may have resulted from neurodegeneration in locus coeruleus, raphe nuclei, pedunculopontine tegmental nucleus, laterodorsal tegmental nucleus and pontine reticular formation, as well as in the limbic system, all regions known to be important for sleep-wake cycle regulation (Sakurai, 2007).
Common behavioral symptoms include sleep-wake cycle disturbance, irritability, hallucinations, and delusions [28].
Common behavioral symptoms include sleep-wake cycle disturbance, irritability, hallucinations, and delusions [ 28].
Besides, it could occur oxyhemoglobin desaturation, altered sleep-wake cycle, insomnia, disruption of sleep architecture, thus, resulting in hypoxia events during sleep.
Furthermore, owing to poor nutrition [ 18], disruption to their sleep-wake cycle [ 15], and disruptions in their natural defenses [ 19], patients with delirium may be more prone to develop sepsis with any given infection.

During delirium, a disruption of the sleep-wake cycle is frequently observed.
During delirium, disruption of the sleep-wake cycle, such as fragmented sleep during the night and sleepiness during the day, is frequently observed [ 9].
Although they may be observed throughout the course of the disease, neurological signs are most often described during stage 2, with a wide panel of sensory, motor and psychiatric disturbances, and the development of disruptions of the sleep-wake cycle, a most characteristic sign that gave its name to the illness [2].
Disruptions in the sleep-wake cycle can be a trigger of manic episodes in bipolar disorder [ 13].
Misalignment of the sleep-wake cycle may lead to sleep disturbance, insomnia, difficulty waking in the morning, and daytime sleepiness.
