Abstract
The writer of this article notes that in order to understand the pathogenesis of sleep disorders, the normal sleep cycle must be understood in a neuro-physiologic context. The writer points out that sleep disorders such as insomnia can be especially distressful in children and adolescents. The writer discusses that aside from the normal developmental circadian adaptations and drift of the sleep-wake cycle in these individuals, secondary causes can inhibit initiation or maintenance of sleep, particularly chronic diseases and mental disorders. While most causes are self-limited and treatment conservative, more elaborate diagnostic and therapeutic interventions may be warranted. The writer concludes that the role of the polysomnography technician is to ascertain the cause of the disorder as well as justify the need for sleep studies while providing useful input for the health care team.
From the Paper
"Sleep disorders can arise from several causes that disrupt the normal sleep cycle in spite of its seemingly grounded cyclic variation in physiology. It can be disrupted when the number of hours required for the individual were not met or were met but with frequent wakeful states in between (sleep fragmentation). The cause must be ascertained first by the technician through a perusal of the patient's history and physical examination with particular emphasis on past and present sleep patterns, aggravating or relieving factors, medications taken, co-morbid diseases, psychiatric co-morbidities such as depression, among others. A polysomnography may be warranted when sleep hygiene strategies fail or an apparent cause is not apparent."

Abstract
This paper examines the physiological and psychology aspects of sleep. It opens with a comprehensive overview of normal sleep and its physiological basis and then details over a dozen of the most common sleep disorders (their basis, diagnosis, treatment, etc.), including insomnia, narcolepsy and sleepwalking.
From the Paper
"The ancient Greeks ascribed the need for sleep to the god Hypnos ("Sleep"), the child of Darkness and Night and the brother of Death, whose power, as he swept across humanity, was so great that even the gods were forced to succumb to him. The prominent place of sleep in ancient mythology serves as a testament to the unequivocal importance it plays in everyday life. Everyone needs to sleep. Although researchers today have devised sophisticated means to define, describe, and detail sleep they still do not fully understand its function. However, when sleep is disturbed, the effects are dramatic and clear. Without sleep we become tired, disoriented, lethargic, mentally dulled, confused, or in extreme cases hallucinatory or assume a state resembling psychosis. Current research on sleep focuses on two main areas: basic sleep mechanisms and sleep physiology and sleep disorders in clinical medicine."

Abstract
The paper introduces, discusses, and analyzes the topic of sleep disorders in the United States, specifically discussing sleep apnea and insomnia, and the treatments available to help patients suffering from these disorders. The paper explains that sleep disorders are one of the most common afflictions affecting Americans today and are caused by a wide variety of issues. The paper concludes with a summary of treatment options to help patients experience restful sleep.
From the Paper
"People experiencing occasional insomnia can try several lifestyle modifications to see if they affect their sleep patterns. For example, they should try to go to bed at the same time every night. If they cannot sleep, they should get up and engage in an activity, such as reading or knitting, until they are tired. They should avoid sleeping during the day. They should also avoid alcohol, coffee, and nicotine before retiring, and they should avoid heavy meals and heavy physical exercise right before bedtime, too."

Abstract
This paper discusses sleep disorders in the elderly and focuses on insomnia. In order to understand the pathogenesis of sleep disorders, the paper begins by describing the normal sleep cycle in a neurophysiological context. It then looks at the causes that may disrupt the normal sleep cycle and discusses the effects of the aging process on sleep disorders.
From the Paper
"In conclusion, sleep disorders such as insomnia can be especially distressful in older adults, particularly the elderly. Aside from the normal circadian drift of the sleep- wake cycle in these individuals, secondary causes can inhibit initiation or maintenance of sleep, particularly chronic diseases and diseases presenting at advanced ages. The use of medications versus non-pharmacologic approaches has been debated, with promising results from clinical trials advocating a non-pharmacologic approach to initiating and maintaining sleep in this population of patients (Sivertsen, Omvik, Pallesen, Bjorvatn, Havik, Kvale et al., 2006). While promising, future studies replicating these results at multiple sites with varied day-night cycles are recommended."

Abstract
This paper presents an overview of rapid eye movement (REM) sleep behavior disorder (RBD). The paper first explains that RBD causes abnormal motor behavior during REM sleep, mainly affects older males and can be associated with neurodegenerative diseases. The paper also looks at treatment options and presents a case study. The paper points out that current limitations with studies on RBD prevent us from knowing all we can about RBD and treatment options.
Outline:
RBD Background
Associations with Neurodegenerative Diseases
Treatment Options
Case Study
Conclusion
From the Paper
"REM sleep behavior disorder, a parasomnia is illustrated by the irregular loss of normal skeletal muscle atonia during REM sleep and is accompanied by complex motor activity while dreaming (Ferini-Strambi, Fantini, Zucconi, Castronovo, Marelli, Oldani, & Cappa, 2005). The loss of REM sleep atonia has been associated with the loss of the inhibition of motor activity that normally is controlled by pontine centers (Mazza, Saucy, Gravel, Michaud, Postuma, Massicotte-Marquez, Decary, & Montplasir, 2006). Behavior release during REM needs the disinhibition of brainstem motor pattern generators, therefore resulting in over-excitation of phasic motor activity; this supplies an anatomic foundation for REM behavior disorder (Mazza et al., 2006)"

Abstract
This paper discusses sleep deprivation in children and refers to studies conducted on the topic. The paper states that children with insufficient sleep showed a lower performance on tests associated with complex tasks as well as a significant correlation between sleep quality and neuro-behavioral functioning. The paper states that these children also had a higher rate of behavioral problems as reported by their parents. The paper continues by relating that there is a relationship linking ADHD with poor sleep since daytime symptoms of insufficient sleep in children overlap with those of ADHD. The paper questions the primary problem and further asks whether ADHD results in behavioral and other sleep disorders, or do primary sleep disorders result in ADHD? The paper concludes that a thorough evaluation of the problem and a treatment plan is required.
From the Paper
" One study suggests that preteens are not getting enough sleep to meet their daily physical and mental needs. This comes from a study of 140 Israeli students in grades two, four, and six. The results show that sleep onset time in second grade was more that one hour earlier than that in sixth grade. The sixth graders reported increased morning drowsiness compared with those of the younger grades. The researchers state the reason for the later sleep onset time is not due to their physiological needs as much as psychosocial reasons. They have increased school demands, a need to feel more like adults by having a more active night life, and there are incentives to stay up later like late-night television shows and internet surfing. The study also links poor sleeping habits with lower maternal education, and adds family stress, illness, and emotional turmoil to the causes."

Abstract
This paper explains that the objectives of the study were to describe the general sleeping habits of College of Arts and Sciences students and to evaluate if the student's course is a factor in his or her sleeping habits (defined as the number of hours of sleep and sleep quality). The author points out that the methodology of the study was a descriptive survey of college students using a stratified random sampling design with the sample size set at a 90% confidence level. The paper concludes that, although statistically the students' courses do not have bearing on what time and how long the students sleep, the respondents themselves believe that their courses affect their sleep. The paper includes several tables, figures and the survey used in the study.

From the Paper
"Sleep deprivation causes emotional disturbances in people. It may also lead to aggressiveness, apathy; result in fluctuations between euphoria and depression and vice versa. One can also experience pain in joints, hallucinations and visions. People also lose their ability to think straight and act quickly. Those who have been sleep deprived for long, usually find it hard to finish a sentence or find an appropriate word to describe something. One's short-term memory also tends to fail. Therefore, one should never economize additional time for sleep. A sleep-deprived individual does everything twice as slow."

From the Paper
"This paper will examine the physiological and psychological interpretations of sleep and dreaming. Prior to the 1940s, scientists considered sleep to be "a passive phenomenon during which major elements of the brain rested" (Long, 1987, p. 796). It has since been discovered that the brain is actually very active during certain periods of sleep. Physiologists have noted two distinct cycles which occur in sleep: the slow wave sleep (SWS) cycle and the rapid eye movement (REM) cycle. During sleep, these two cycles alternate from one to the other approximately once every ninety minutes. During the SWS phase, the sleeper's brain wave patterns slow down dramatically. During the REM phase the brain wave patterns become so active at times that they resemble those of a person who is fully awake (Palca, 1989, p. 352)."

Abstract
Evidence gathered from research suggests a strong and positive correlation between sleep and memory consolidation. Based on these research results, this paper argues that it is clear that sleep is not only essential for consolidating what is learnt but also a prerequisite for imbibing new knowledge. A brief outlook into the nature of sleep and memory followed by a review of some of the available research studies provides the reader with a better understanding of the role of sleep in the process of memory.

From the Paper
"Sleep is an important natural physiological process that consumes almost a third of our lifetime. Many early researches have helped our understanding of the importance of sleep in regulating hormones and other metabolic functions of the body. Researchers have also devoted much attention to understanding the effects of sleep on one of the important functions of the brain, namely memory. Ever since the pioneering research by Jenkins and Dallenbach, which showed positive evidence for the role of sleep in augmenting the memory process researchers have made considerable progress in understanding the process of memory. [C. Smith] Recent Neuroanatomical studies have shed more light on this subject clearly suggesting a positive role of sleep in improving the memory and learning process. In view of these evidences, there are valid reasons to strongly correlate the existing trend of sleep deprivation in the society to the cognitive deficits."

The paper also provides ways of avoiding sleep deprivation. The writer emphasizes the importance of good sleeping habits to ensure a well-balanced, healthy life.
From the Paper
"Sleep. We cannot live without it, but sometimes, it seems like we would like to. Sleep deprivation has become much more common in our hectic and demanding society. "Like the religious ascetics of medieval times, many people today regard sleep as 'time lost.' They regret that the day is only twenty-four hours long and that they do not have time to do all the things they should do or would like to do" (Borbaely 158). One report notes that most people would rather sleep an hour more than they usually do, and in another study, people who slept less that six hours a night displayed the tendency to fall asleep during the day, or complain of being tired during the day."

Abstract
After a general outline of sleep and what happens while we are sleeping, this paper goes on to discuss the body's biological need for sleep, the sleeping problem known as insomnia, and how it can affect one's health. The paper also looks at some possible causes of insomnia and how it can be treated.
From the Paper
"We spend about one third of our life sleeping. Sleep is defined as the suspension of consciousness during which the powers of the body are restored (ThinkQuest, 2003). The brain is not at rest during sleep as popularly thought, but is extremely active and it is the brain that tells us when it is time to sleep. Sensations of light taken in from the retina are transferred through the nerves to an area of the brain determines the amount of light exposure and adjusts the body accordingly. The exact purpose of sleep remains a mystery, but researchers speculate that during certain stages of sleep, the brain is testing, strengthening, or somehow improving our neurons."

Abstract
This paper explains that women with premenstrual dysphoric disorder (PMDD) complain of irritability, anger, tension, marked depressed mood, mood lability, lethargy, sleep disturbance, limited concentration and many physical symptoms to such a degree of severity that their quality-of-life is seriously compromised. The author points out that inhibitors of serotonin reuptake, fluoxetine (Sarafem), may be an effective therapy. The paper states that PMS and PMDD are far more common in a woman's later years of fertility because these syndromes are caused by the lower estrogen levels and higher progesterone levels found more commonly in the latter half of a woman's reproductive life.

From the Paper
"Rubinow and Schmidt note that unlike mood disorders associated with the abnormal function of other endocrine glands (e.g., the adrenal or thyroid glands), PMS occurs in the context of normal ovarian function. The question then is why different women have different responses to what is ostensibly the same stimulus. This question is central to understanding behavior and is currently best addressed by studies in animals. Pharmacologic sensitization, kindling, and conditioning provide experimental models in which both the biologic and behavioral responses to a given stimulus are profoundly altered and determined by past experience with the stimulus. In these models, a stimulus that originally produces little or no effect may change the biologic substrate in a way that dramatically increases the severity of behavioral effects, purely as a function of repetition and the passage of time. Although the relevance of these models to PMS is uncertain, it is noteworthy that PMS is most frequently observed more than a decade after the initiation of ovarian cyclicity."

Abstract
This paper explains that the tendency of adolescents to stay up later at night and sleep later in the morning, as compared to prepubescent children and adults, is not caused by choice but rather a natural circadian phase delay experienced by adolescents. The author points out that the ability to effectively interact with peers while learning and processing novel information may be diminished in many sleep-deprived adolescents. The paper states that a series of surveys and questionnaires will be used to gather relevant data will be gathered from parents, teachers and school administrators exploring the negative relationship of early start times and the health and well-being of adolescents.

"Approximately every 90-minute during sleep, the brain goes through four stages of sleep, from light sleep to deep sleep. The most important stage is Rapid Eye Movement (REM) sleep, also called "the dream stage." As you sleep, your brain become aware of the situation and take measures to solve it. Schools are to provide all students with knowledge and the opportunity to achieve regardless of limitations. Schools need to ensure good conditions in which learning takes place. If schools opened later, it would help the grades, attitudes and health of the students."

Abstract
Paper deals with sleep deprivation in America?s youth and students. Sleep is defined and the process is briefly explained. Includes explanations of poor sleep habits, sleep mechanisms and past catastrophic events relating to sleep deprivation.
From the Paper
"Sleep deprivation among teens and adolescents has long been an overlooked problem in this country. According to the National Highway Traffic Safety Administration, there are as many as 100,000 car crashes each year that are linked to drowsy driving. Over half of those crashes involved adolescent drivers ages 15-24. (NTSA, 1999) Furthermore, those numbers are increasing each year at an alarming rate."
