Sleepwalking :: Biology Essays Research Papers

Sleepwalking Many throng have heard of noctambulism and even know roughly symptoms that exceptt against the disorder, but is there more to the story than just waking up during the night and wandering around in an unaware state? What real causes someone to sleepwalk? To try to conceive the answers to these questions it is important to understand not that what kind of disorder it is, but who has the disorder, how frequently it occurs, what the symptoms are, as soundly 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 create disruptive sleep-related events. rousing 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 being 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 have in mind these actions (1).One of the most common types of arousal disorders is somnambulism, more ordinarily know 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 years 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 get hold of prevalence of sleepwalking in adults is not known, it is estimated to be as blue as 10%.(4). It has also been noted that those individuals who start to sleepwalk as adults are more prone to serious 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 b e linked to mental disturbances other 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 brainpower that controls muscle function is aroused and the sleepwalker begins to move even though he or she is still asleep (2).
