What is the purpose of polysmnography?
It can help diagnose sleep apnea, narcolepsy, parasomnias, and seizures.
What are the signs of parasomnia?
I'm also asking about the signs of this sleep disorder(parasomnias)because i don't know if i have it already.
What are the symptoms of parasomnias?
Abnormal behaviors or movements during sleep, such as sleep walking, talking in one's sleep, nightmares, and bedwetting.
How does one know if they have the condition called parasomnia?

Secondary parasomnias are things that occur regardless of being asleep, but can cause a person to wake up, such as indigestion or reflux.

Do people know what they are doing when they are asleep?
Typically, people are not aware of their actions or surroundings when they are asleep. While it is possible to perform automatic behaviors or engage in activities while asleep, known as sleepwalking or parasomnias, individuals are usually not conscious or in control of these actions.
Do you ever wake yourself up sleeptalking?
Okay, so the question sounds a bit confusing, so let me explain it. Last night I had an incredibly vivid lucid dream, about sleepwalking and talking. God knows why, but when I was dreaming of sleepwalking, I could feel things in complete detail and it felt real but I knew I was asleep, then about an hour later I was still dreaming, I knew I was asleep but like I felt almost awake. Then very suddenly, I felt my door open - which isn't possible as I lock it from the inside, and loud music began to play. Suddenly, I screamed "F**K OFF" At this point I woke up with a snort, confused. I don't know if I actually was sleepwalking and talking and I don't have a roommate or anything so there's no way of someone telling me. Has anyone else experienced this, and how can I find out for sure if I suffer from parasomnias.
Sleep disorders - overview?
DefinitionSleep disorders are problems with sleeping, including trouble falling or staying asleep, falling asleep at the wrong times, too much sleep, or abnormal behaviors during sleep.Causes, incidence, and risk factorsThere are more than 100 different sleeping and waking disorders. They can be grouped into four main categories:Problems falling and staying asleep (insomnia)Problems staying awake (excessive daytime sleepiness)Problems sticking to a regular sleep schedule (sleep rhythm problem)Unusual behaviors during sleep (sleep-disruptive behaviors)PROBLEMS FALLING AND STAYING ASLEEPInsomniaincludes trouble falling asleep or staying asleep. Episodes may come and go, last up to 3 weeks (be short-term), or be long-lasting (chronic).PROBLEMS STAYING AWAKEPeople with excessive daytime sleepiness feel tired during the day. Symptoms that are not caused by a lack of sleep or interrupted sleep are called hypersomnia.Causes of this problem include:Medical conditions such as fibromyalgia and low thyroid functionMononucleosisor other viral illnessesNarcolepsy and other sleep disordersObesityWhen no cause for the sleepiness can be found, it is called idiopathic hypersomnia.PROBLEMS STICKING TO A REGULAR SLEEP SCHEDULEProblems may also occur when you do not stick to a regular sleep and wake schedule. This occurs when people travel between time zones and with shift workers who are on changing schedules, especially nighttime workers.Disorders that involve a disrupted sleep schedule include:Irregular sleep-wake syndromeJet lag syndromeParadoxical insomnia (the person sleeps a different amount than they think they do)Shift work sleep disorderSLEEP-DISRUPTIVE BEHAVIORSAbnormal behaviors during sleep are called parasomnias. They are fairly common in children and include:Sleep terrorsSleepwalkingREM sleep-behavior disorder (a person moves during REM sleep and may act out dreams)Reviewed ByReview Date: 08/16/2011David B.

What are some common sleep disorders?
There are many types of sleeping disorders. You'll be surprised to know that some of them are still a mystery to doctors and being researched upon. The more common ones are : 1. Restless Leg Syndrome - where there is an urge to move the limbs continuously, often in an uncontrollable manner 2. Periodic Limb movement - an involuntary rhythmic movement of the limbs that happens at random 3. Insomnia - inability to sleep for any fair length of time 4. Sleep Apneas - A gasping for air, chocking, loud snoring or never getting a refreshing sleep 5. Night eating syndrome - characterized by frequent night waking in which the patient is unable to fall back to sleep unless he/she eats something. 6. Narcolepsy - Uncontrollable urge to fall asleep unexpectedly in the middle of an activity or conversation. If you are having trouble sleeping or sleeping and finding that you do not feel refreshed when you awake, consider seeking help from a professional.
Isolated sleep paralysis?
DefinitionIsolated sleep paralysis is a type of paralysis associated with a sleep disorder. Sleep paralysis is the inability to perform voluntary muscle movements during sleep.See also: NarcolepsyAlternative NamesSleep paralysis - isolatedCauses, incidence, and risk factorsIsolated sleep paralysis is more likely to happen during the first two hours of sleep. Not getting enough sleep or sleeping on the back may cause more frequent episodes.Though this condition may be associated with narcolepsy, many people who do not have narcolepsy have isolated sleep paralysis. It is common in adults and is also seen in children.Most people with isolated sleep paralysis do not have any mental health problems. However, these episodes seem to occur more often in people with:Bipolar illnessDepressionAnxiety disordersPost-traumatic stress disorderRarely, it runs in families.SymptomsPeople with isolated sleep paralysis have episodes that last from a few seconds to 1 or 2 minutes in which they are unable to move or speak.These spells end on their own or when the person is touched or moved.Rarely, the person may have dream-like sensations or hallucinations, which may be scary to them.Signs and testsIf you do not have other symptoms of narcolepsy, there is usually no need to perform sleep studies.ReferencesStores G.
