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.
Outline and evaluate one or more explanations for sleep disorders (24 marks) Some sleep disorders are serious enough to interfere with normal physical, mental, social and emotional functioning. Insomnia can cause problems with sleep patterns and in particular difficulties falling asleep or maintaining sleep. Some people who have very little sleep suffer no ill consequences and so a diagnosis of insomnia is not based on the number of hours slept but when the resulting daytime fatigue causes severe distress of impairs work, social or personal functioning for more than one month. Insomnia may be either secondary or primary. Secondary insomnia is when insomnia is caused by a psychiatric or medical disorder and is therefore often a symptom instead of another disorder.
Bipolar disorder is a brain disorder that causes unusual shifts in mood, energy, activity levels, and the ability to carry out daily tasks. The symptoms of bipolar disorder are severe; they are very different from the normal ups and downs that everyone goes through. The results of bipolar disorder symptoms can result in damaged relationships, poor performance in work or school, and even suicide. However, bipolar disorder can be treated and people with the illness can lead full lives as if they did not even have the disorder. The disorder usually develops between the late teens and the early adult years; most cases start before the age of twenty five.
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.
Describe and evaluate lifespan changes in sleep (24 marks) As humans grow from infancy to old age, there are major changes in the amount and type of sleep that they experience. During infancy, babies tend to sleep about 16 hours a day, but their sleep is not continuous. They usually wake up every hour or so as a result of their sleep cycles being shorter than the adult 90-minute cycle. Infants have quiet and active sleep which are immature versions of SWS and REM sleep. There are differences between adult and infant sleep.
Experimental Research PSY/285 February 17, 2013 Experimental Research Pharmaceutical Research: Sleeping Aids There are many different kinds of sleeping aids that can help someone fall asleep today. Insomnia is when a person has a hard time falling asleep, staying asleep, or a disturbance in the quality of sleep a person gets that will make them feel they are not well rested when they do wake. Insomnia is more common today then we think, about 10% of adults suffer from severe insomnia. Lack of sleep may cause someone to have no motivation, mood swings, and not be able to function to their full potential. Insomnia has also been known to cause depression, anxiety, and stress, which in turn can cause other health problems.
Running head: Module D Test Module D Test Jason Robertson PSYCHOLOGY 1101 – Module D Test Dr. Ewing 2/10/13 Module D Test Sleepwalking is probably the most common sleep disorders. Sleepwalking is most commonly seen in children, although it can be seen in adults and the elderly. Boys are more likely to be sleepwalkers than girls are, and the disorder usually runs its course before the teen years. The rates of the occurrences can vary from person to person, some may only sleep walk once a month, while others may sleep walk nightly. I have never experienced sleep walking or know anyone who has so it’s hard for me to understand it.
While many parents claim that they know there children’s sleeping patterns and make sure they get enough sleep, more than one half (56%) of adolescents say they get less sleep than recommended. Many teens claim they get to bed on time but the quality of sleep is horrible. Many factors contribute to this weather
Trinh Le Larry Bounds AP Language and Composition 26 August 2014 Amount of Sleep Required Everybody goes through a 24-hour cycle for each and every day. Within those 24 hours people can choose to be lazy, active, productive, adventurous, studious, or even curious. No matter what the answer is, one thing we all have in common is that we all need sleep. Sleep is a condition when our body and mind recurs for many hours every night, in which the body system is inactive and relaxed. Therefore, after a long day of doing nothing or work, the human body has to be fatigued and needs rest or even better the body and mind needs sleep.
It is through this research that scientists have recognized the differences in brains of people with bipolar and those with healthy brains who are not exhibiting signs of the illness. It is these differences in brain function that are assisting scientists in developing insight into the underlying causes of the disorder to gain insight into which treatments will be most effective in treating each type of the disorder. (Soares, 1997) Despite the extensive research, Bipolar Disorder remains one of the most difficult disorders to diagnose and
