Hypersomnia can be secondary to disorders such as clinical depression, multiple sclerosis, encephalitis, epilepsy, or obesity. [17] Hypersomnia can also be a symptom of other sleep disorders, like sleep apnea. [17] It may occur as an adverse effect of taking certain medications, of withdrawal from some medications, or of substance use. [17]
A sleep disorder, or somnipathy, is a medical disorder affecting an individual's sleep patterns, sometimes impacting physical, mental, social, and emotional functioning. [1] Polysomnography and actigraphy are tests commonly ordered for diagnosing sleep disorders.
Idiopathic hypersomnia (IH) is a neurological disorder which is characterized primarily by excessive sleep and excessive daytime sleepiness (EDS). [1] Idiopathic hypersomnia was first described by Bedrich Roth in 1976, and it can be divided into two forms: polysymptomatic and monosymptomatic.
An overnight sleep study is usually not needed to detect this disorder, but may be indicated if other sleep disorders, such as sleep apnea and periodic limb movement disorder, seem likely. The overnight sleep study is called polysomnography. It charts brain waves, heart beat, muscle activity, and breathing during sleep.
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 Multiple Sleep Latency Test (MSLT) measures a person's physiological tendency to fall asleep during a quiet period in terms of sleep latency, the amount of time it takes for someone. An MSLT is normally performed after a nocturnal polysomnography to ensure both an adequate duration of sleep and to exclude other sleep disorders. [10]
A flying hack making the rounds on TikTok that suggests travelers should buckle their seatbelts around their ankles for a more comfortable sleep has experts alarmed.
A circadian rhythm is an entrainable, endogenous, biological activity that has a period of roughly twenty-four hours. This internal time-keeping mechanism is centralized in the suprachiasmatic nucleus (SCN) of humans, and allows for the internal physiological mechanisms underlying sleep and alertness to become synchronized to external environmental cues, like the light-dark cycle.
