Sleep-related hallucinations, also known as hypnogogic (going to sleep) and hypnopompic (on awakening) are vivid hallucinations that can be auditory, visual, or tactile and may occur independent of or in combination with an inability to move (sleep paralysis). Narcolepsy is a clinical syndrome of hypothalamic disorder, [6] but the exact cause ...
Episodes of sleep paralysis, regardless of classification, are generally short (1–6 minutes), but longer episodes have been documented. [8] It can be difficult to differentiate between cataplexy brought on by narcolepsy and true sleep paralysis, because the two phenomena are physically indistinguishable. The best way to differentiate between ...
Sleep paralysis, characterized by temporary paralysis of the body shortly before or after sleep. Sleep paralysis may be accompanied by visual, auditory or tactile hallucinations. It is not a disorder unless severe, and is often seen as part of narcolepsy.
Presenting with the tetrad of symptoms (excessive daytime sleepiness, sleep-onset paralysis, hypnagogic hallucinations, and cataplexy symptoms) is strong evidence of the diagnosis of narcolepsy. A multiple sleep latency test [clarification needed] is often conducted to quantify daytime sleepiness. [14] Cataplexy can sometimes be misdiagnosed as ...
The major feature of RBD is loss of muscle atonia (i.e., the loss of paralysis) during otherwise intact REM sleep (during which paralysis is not only normal but necessary). The loss of motor inhibition leads to sleep behaviors ranging from simple limb twitches to more complex integrated movements that can be violent or result in injury to ...
Humans may suffer from various sleep disorders, including dyssomnias, such as insomnia, hypersomnia, narcolepsy, and sleep apnea; parasomnias, such as sleepwalking and rapid eye movement sleep behavior disorder; bruxism; and circadian rhythm sleep disorders. The use of artificial light has substantially altered humanity's sleep patterns. [10]
Narcolepsy, idiopathic hypersomnia, circadian rhythm sleep disorder, sleep apnea, others Excessive daytime sleepiness ( EDS ) is characterized by persistent sleepiness and often a general lack of energy, even during the day after apparently adequate or even prolonged nighttime sleep.
Sleep paralysis occurs when your mind is awake, but your body can’t move, Xue Ming, a sleep expert and professor of neurology at the Rutgers New Jersey Medical School, tells me. You can ...
