Sleepwalking :: Biology Essays Research Papers

Sleepwalking Many people have heard of sleepwalking and even know about symptoms that surround the disorder, moreover is there more to the story than just waking up during the night and wandering around in an unaware state? What actually causes someone to sleepwalk? To learn to understand the answers to these questions it is important to understand not only what kind of disorder it is, but who has the disorder, how frequently it occurs, what the symptoms are, as well as what the treatments are. By exploring these areas, it may be possible to better understand the disorder as well as dispel old notions about it.The Parasomnias are disorders that intrude into the sleep process and pretend disruptive sleep-related events. Arousal disorders are parasomnia disorders presumed to be due to an abnormal arousal mechanism. These arousals occur when a person is in a mixed state of existence both asleep and awake, generally coming from the deepest stage of nondreaming sleep, stages 3 and 4. This means a person is awake enough to act out complex behaviors but still asleep and not aware or able to remember these actions (1).One of the most common types of arousal disorders is sleepwalking, more commonly known as sleepwalking. Somnambulism affects children much more regularly than adults. In fact, sleepwalking affects approximately 1% to 17% of children and is more frequently seen in boys. Interestingly, 15% of children aged 5-12 geezerhood sleepwalk at least once, but only 3-6% sleepwalk more than once (5). It has been noted that the incidence of sleepwalking decreases with age. Although the exact prevalence of sleepwalking in adults is not known, it is estimated to be as high as 10%.(4). It has also been noted that those individuals who start to sleepwalk as adults are more prone to expert problems with it. Because it is found more commonly in children, who are undergoing many physical and chemical changes, if it is seen to start in adults it is thought to be linked to mental disturbances new(prenominal) than fatigue or anxiety. However, mental disturbances can be present without counting as a symptom(3). No one seems to know exactly what the cause of somnambulism is, but there are theories that have been suggested. Once asleep, it is thought that the part of the brain that controls muscle function is aroused and the sleepwalker begins to move even though he or she is still asleep (2).
