Presentation
The HLA DQB1*05:01 allele was present in 41% (29/71) compared to 24.2% in the regional-matched reference allele group (p 0.05). This haplotype prevalence did not differ within the NREM parasomnia type. [ncbi.nlm.nih.gov]
The DQB1*06:02 allele was present in 22 (31.9%) of patients. Five patients were heterozygous for both DQB1*05:01 and DQB1*06:02. [jcsm.aasm.org]

Excessive Daytime Sleepiness
Excessive Daytime Sleepiness Excessive daytime sleepiness refers to the inability to stay alert during the major awake period of the day, resulting in falling asleep at inappropriate times. [clevelandclinicmeded.com]
This finding underlines the reports of other authors that excessive daytime sleepiness is not only an important characteristic of sleepwalking, but NREM parasomnia itself. [jcsm.aasm.org]
In extreme cases, these brief arousals following the leg movements disturb sleep so much that they cause excessive daytime sleepiness. [healthysleep.med.harvard.edu]

Tachypnea
This can evolve into spells including intense autonomic activation with vocalization, tachycardia, tachypnea, mydriasis, diaphoresis, and sleep terrors or sleepwalking. [psychiatrictimes.com]
Nightmares are frightening dreams that occur during REM sleep and are associated with an increase in heart rate (tachycardia), an increase in the rate of breathing (tachypnea), profuse sweating, and arousal. [emedicinehealth.com]
The autonomic hyperactivity includes tachypnea, tachycardia, mydriasis and diaphoresis. The patients usually appear terrified and inconsolable and are amnestic or may have a vague recollection of the event. [ncbi.nlm.nih.gov]
They consist of arousals from deep NREM sleep and are characterized by intense behavioral manifestations of fear and autonomic hyperactivity (eg, tachycardia, tachypnea, pupillary dilation, and diaphoresis). [clevelandclinicmeded.com]

Suggestibility
Attarian suggests scheduled or anticipatory awakening as a behavioural technique to prevent these events [12]. [hindawi.com]
Additionally, 42.6% of the 417 patients had a history suggestive of RBD [11]. [documents.tips]
Another theory suggests that RMD is a learned, self-stimulating behavior to alleviate tension and induce relaxation, similar to tic movements. [14] An alternative theory suggests that the rhythmic movements help develop the vestibular system in young [en.wikipedia.org]
While many studies over the years have associated obstructive sleep apnea with a higher risk of heart attacks and stroke, the Loyola study suggests sleep apnea also increases parasomnia symptoms. [belmarrahealth.com]
One theory suggests that parasomnias are caused by abnormal electrical discharges coming from deep within the brain. [suburbansleep.com]

Night Terrors
Night terrors are just bad dreams. Eating cheese can give you nightmares and night terrors. [thehumanthebody.com]
Sleep Terrors / Night Terrors: A person experiencing a night terror or sleep terror abruptly awakes from sleep in a terrified state. [sleepdisordersguide.com]
They include night terrors, nightmares, sleepwalking, and bedwetting. Night Terrors Night terrors (also known as Pavor Nocturnus) are characterized by a sudden arousal from sleep with a piercing scream or cry. [m.rossa-editorial.kidshealth.org]
People with night terrors don’t remember the experience in the morning. Due to limb movements during night terrors, people experiencing night terrors can be a danger to themselves and others. [emeraldsleep.com]
Most often, the child will not remember the night terror the next morning. Night terrors are not nightmares caused by a bad dream. [jamanetwork.com]

Screaming
In night terrors, patients arouse from deep sleep and scream. They look frightened. If awakened, they are confused. This also usually happens in children. In c onfusional arousals, patients wake up from sleep and are confused. [sleepandattentiondisorders.com]
Sleep terrors are like severe nightmares but with intense fear often accompanied by screaming and fighting. Fifteen per cent of children experience night terrors after general anesthesia, occurring anywhere up to 2 weeks after surgery. [medicinenet.com]
Night terrors—These severe attacks cause people, usually children, to appear to wake up and scream in fear or panic. However, these individuals are typically inconsolable, and tend to have no recollection of the event the following day. [brighamandwomens.org]
They can cause the sleeper to cry, scream, walk, move about and or curse. These seizures can be treated with medications. REM Behavior Disorder REM Behavior Disorder is the ability to act out your dreams. [nithra.com]

Forgetful
People who experience sleep terrors usually forget the experience afterwards, although they may have a partial memory of it. Further Reading Parasomnias - What are Parasomnias? REM Parasomnias [news-medical.net]
Workup
[…] studies are indicated in the workup of routine parasomnias No imaging studies are required Polysomnography (PSG), with or without multiple sleep latency testing, is reserved for the few cases in which the diagnosis is still unclear after the history [emedicine.medscape.com]
A complete sleep history and diagnostic workup including polysomnography is important to rule out the differentials and reach a conclusive diagnosis of parasomnia. [ncbi.nlm.nih.gov]
Importance of Polysomnography in the Work-up of Parasomnia The finding that at least subtle behavioral abnormalities were observed during a one-night V-PSG underlines the importance of V-PSG in the workup of NREM-parasomnia, as it does not only serve [jcsm.aasm.org]
C 29, 30 If restless legs syndrome is suspected in a child, management should include a workup for iron deficiency and avoidance of triggers. [aafp.org]
Treatment

Treatment Being the least studied parasomnia, little is known about treatment possibilities. [hindawi.com]
Therefore, both psychological and pharmacologic approaches are necessary for the management and treatment of nightmare disorders. [countingsheep.net]

Prognosis
The book uncovers the professional issues that clinical neuropsychologists deal with daily, including neurogenerative disorders, acquired disorders, ethical practice issues, interviewing, testing, prognosis and treatment planning, drug prescriptions, [books.google.com]
Prognosis Most children with sleepwalking disorder grow out of it. Adult sleepwalkers tend to have more protracted waxing and waning phases of the phenomenon. [patient.info]
[33] The prognosis for other parasomnias seems promising. [en.wikipedia.org]
Etiology
The onset of Sleepwalking Disorder in adults with no history of sleepwalking as children should prompt a search for specific etiologies such as substance use or a neurological condition. [sleep.health.am]
It is possible that complex (sexual) behaviour in sleep is multifaceted in its etiology. [ww1.cpa-apc.org]
Etiology Genetic factors Sleepwalking occurs more frequently in monozygotic twins and is 10 times more likely if a first-degree relative has a history of sleepwalking. An increased frequency of DQB1*04 and *05 alleles is reported. [emedicine.medscape.com]
Epidemiology
Epidemiology Prevalence of RLS could be as high as 10-20% in the older age group and it is increasingly common with age. [patient.info]

Review Epidemiology Parasomnias are more often seen in children than in the adult population. In children, the NREM parasomnias are more common than REM parasomnia. [ncbi.nlm.nih.gov]
Other epidemiological evidence suggests some association between sleepwalking, major depression, and obsessive-compulsive disorder, although again with no established causal relationship.3 Generally, there is no need for interventions when confusional [psychiatrictimes.com]

Prevention
Prevention The best way to prevent sleepwalking is to get a better night’s sleep. In some cases, stress or certain medications can contribute to sleepwalking. [columbianeurology.org]
It also might be wise to install gates at the top of staircases to prevent dangerous falls. Alcohol use can sometimes trigger sleepwalking episodes. Avoiding alcohol might help to prevent sleepwalking in some people. [elcaminohospital.org]
But precautions should be taken to prevent injuries such as falling down stairs or climbing out of a window. You probably do not need to visit your provider. [medlineplus.gov]
In addition, they should undergo appropriate treatment and management in order to prevent future parasomnia behaviors. [utmb.influuent.utsystem.edu]
To prevent falls, don't let your sleepwalker sleep in a bunk bed. Remove sharp or breakable things from around your child's bed. Keep dangerous objects out of reach. [kidshealth.org]
