When a person struggles to fall asleep or stay asleep without any obvious cause, it is referred to as insomnia, [2] which is the most common sleep disorder. [3] Other sleep disorders include sleep apnea , narcolepsy , hypersomnia (excessive sleepiness at inappropriate times), sleeping sickness (disruption of the sleep cycle due to infection ...
Narcolepsy is a chronic neurological disorder that impairs the ability to regulate sleep–wake cycles, and specifically impacts REM (rapid eye movement) sleep. [1] The pentad symptoms of narcolepsy include excessive daytime sleepiness (EDS), sleep-related hallucinations, sleep paralysis, disturbed nocturnal sleep (DNS), and cataplexy. [1]
The condition can be triggered by sleep deprivation, psychological stress, or abnormal sleep cycles. The underlying mechanism is believed to involve a dysfunction in REM sleep. [2] Diagnosis is based on a person's description. Other conditions that can present similarly include narcolepsy, atonic seizure, and hypokalemic periodic paralysis. [2]
Stress often leads to difficulties falling asleep and staying asleep, however, a lack of sleep can also contribute to one's stress levels.

Morvan's syndrome is an example of a rarer autoimmune illness that can also lead to hypersomnia. [23] Celiac disease is another autoimmune disease associated with poor sleep quality (which may lead to hypersomnia), "not only at diagnosis but also during treatment with a gluten-free diet."
However, SRED should not be confused with nocturnal eating syndrome, which is characterized by an excessive consumption of food before or during sleep in full consciousness. [ 22 ] [ 23 ] Since sleep-related eating disorders are associated with other sleep disorders, successful treatment of the latter can reduce symptoms of this parasomnia.
Subjects undergo a series of five 20-minute sleeping opportunities with an absence of alerting factors at 2-hour intervals on one day. The test is based on the idea that the sleepier people are, the faster they will fall asleep. [15] [16] The Maintenance of Wakefulness Test (MWT) is also used to quantitatively assess daytime sleepiness. This ...
