Studies in animals suggest that a hypernyctohemeral syndrome could occur as a physiologic aftereffect of lengthening the sleep–wake cycle with chronotherapy". [7] According to the American Academy of Sleep Medicine (AASM), "patients with free-running (FRD) rhythms are thought to reflect a failure of entrainment ".
Insufficient quality or quantity of night time sleep [5] Obstructive sleep apnea [6] Misalignments of the body's circadian pacemaker with the environment (e.g., jet lag, shift work, or other circadian rhythm sleep disorders) [7] Another underlying sleep disorder, such as narcolepsy, sleep apnea, [8] idiopathic hypersomnia, or restless legs syndrome
The most common sleep-related symptom of bipolar disorder is insomnia, in addition to hypersomnia, nightmares, poor sleep quality, OSA, extreme daytime sleepiness, etc. [27] Moreover, animal models have shown that sleep debt can induce episodes of bipolar mania in laboratory mice, but these models are still limited in their potential to explain ...
The surgical treatment for velopalatal insufficiency may cause obstructive sleep apnea syndrome. When velopalatal insufficiency is present, air leaks into the nasopharynx even when the soft palate should close off the nose. A simple test for this condition can be made by placing a tiny mirror on the nose, and asking the subject to say "P".
Individuals who are overweight or obese can experience obstructive sleep apnea, gastroesophageal reflux disease (GERD), depression, asthma, and osteoarthritis, all of which can disrupt a good night's sleep. [92] In rats, prolonged, complete sleep deprivation increased both food intake and energy expenditure, with a net effect of weight loss and ...
Absence of insufficient sleep syndrome; Absence of cataplexy; Absence of other causes of hypersomnia; The presence of positive MSLT tests. [32] [33] [34] The latest ICD-10 defines IH with long sleep time as a neurological disorder that is a rare sleep disorder characterized by prolonged sleep at night and extreme sleepiness during the day ...
Also, researchers have shown that disrupting stage IV sleep consistently in young, healthy subjects causes a significant increase in muscle tenderness—similar to that experienced in "neurasthenic musculoskeletal pain syndrome". This pain resolved when the subjects were able to resume their normal sleep patterns. [22] Chronic kidney disease is ...
In contrast, sleep-related hypoventilation occurs when there is a malfunction of the brain's drive to breathe. [18] The underlying cause of the loss of the wakefulness drive to breathe encompasses a broad set of diseases from strokes to severe kyphoscoliosis. [18]
