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
Sleep apnea is the second most frequent cause of secondary hypersomnia, affecting up to 4% of middle-aged adults, mostly men. Upper airway resistance syndrome (UARS) is a clinical variant of sleep apnea that can also cause hypersomnia. [8] Just as other sleep disorders (like narcolepsy) can coexist with sleep apnea, the same is true for UARS.
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]

Sleep apnea is a serious medical condition that causes interruptions in your sleep leading to a wide range of symptoms. Learn more about the condition and how to get diagnosed.
Individuals with IH share common symptoms including excessive daytime sleepiness, sleep inertia, brain fog, and long sleep periods. [10] [11] [12]Excessive daytime sleepiness, characterized by persistent sleepiness throughout the day and often a general lack of energy, even during the day after apparently adequate or even prolonged nighttime sleep.
Some of those people had sleep problems, but they could mostly be explained by age, sleep apnea, or other causes. But the 50 subjects in the study whose brains had Alzheimer's-related proteins all ...
In individuals deprived of sleep, somnolence may spontaneously dissipate for short periods of time; this phenomenon is the second wind, and results from the normal cycling of the circadian rhythm interfering with the processes the body carries out to prepare itself to rest. The word "somnolence" is derived from the Latin "somnus" meaning "sleep".
