Several specialized tests, which can be performed in a sleep disorders clinic or sleep lab, usually are required before a diagnosis can be stated. The two most essential tests in confirming a diagnosis of narcolepsy are the polysomnogram (PSG) and the multiple sleep latency test (MSLT). The PSG is an overnight test that takes continuous measurements while a patient is asleep in order to document abnormalities in their sleep cycle. A PSG reveals REM sleep that occurs at abnormal times in the sleep cycle and eliminates the possibility that particular individual's symptoms coming from another condition. The MSLT is performed during the day to measure a person's tendency to fall asleep and to determine whether isolated elements of REM sleep intrude at inappropriate times during the waking hours.
Researchers have been puzzled by the many features of how and why the brain works the way it does. Scientists have been performing sleep and dream studies for decades and I want to learn more about dreams and the psychology behind it. In my research paper I will show statistics of dreams being remembered as well as the different sleep disorders that effect dreams. I will also go through the science behind REM and the different stages of sleep. I also want to show an example of different people going through tests to show when they are at REM sleep.
Despite their appearance, sleep terrors are not nightmares. Nightmares are vivid dreams that occur during REM sleep, and most people can recall most or all of their nightmares. ( http://stanfordhospital.org/clinicsmedServices/clinics/sleep/sleep_disorders/nighttime-sleep-behaviors.html) On the other hand, sleep terrors occur during the deepest stages of sleep when dreaming does not occur. Commonly one who has a sleep terror cannot recall what was so frightening to them. It is typical during a sleep terror for a person to scream, sweat, have a rapid pulse and sit up in bed.
Outline and Evaluate one explanations of sleep disorders Narcolepsy is caused by disruption of sleep wake cycle, where sufferers fall asleep randomly, often whilst engaging in some kind of activity. It is a long-term neurological condition that disrupts normal sleeping patterns which affects 1 in 2000 individuals. The two main symptoms are excessive daytime sleepiness and episodes of cataplexy which is loss of muscular control which often happens when laughing. Other symptoms include sleep paralysis and hallucinations, both experienced when falling asleep and waking up, and disturbed night-time sleep. Narcolepsy usually begins in adolescence and the type of severity of symptoms vary from person to person and may either worsen or improve with time.

Bad habits can cause many sleep problems. Health issues of all kinds can effect sleeping. Lack of exercise or stress are common problems as well. 2. How does alcohol affect sleep?
We try to fit everything into one day and then work into the night to accomplish the impossible. According to “How Sleep Debt Hurts College Students”, by June J. Pilcher and Amy S. Walters, “College students are not aware of the extent to which sleep deprivation impairs their ability to complete cognitive tasks…”. Even if we get only a few hours of sleep, we college students use a variety of methods to try and beat Mr. Sandman. From coffee to energy drinks to pinching ourselves, there are many ways we try and cram as much as possible into a 24-hour period. One question I have come across in my years as a student isn’t the how we say awake, but the why we stay awake.
