The elderly population has been increasing over the past decade and now with the baby boomers entering into this population it only applies more pressure to an ever increasing dilemma on how to improve their health. Sleep is essential to a person’s well being and cognitive function. Research studies have shown that there is significant decline in a person’s cognitive function when they do not receive an adequate night’s sleep. The secret to aging healthfully is getting enough sleep to allow the body to heal and rejuvenate from the day’s experiences and traumas. This paper is a review of the literature in response to sleep and its effects on cognitive function in the elderly population with a brief discussion on nursing implications.
Sleep is defined according to Bombois et al, 2010 as a “psychological process characterized by several cycles of different sleep states within a twenty-four hour period.”( Bombois et al, 2010) The article describes that people with these disturbances are at an increase risk for “mortality, cardiovascular changes and neurobehavioral co-morbities as well.” This article describes dementia patients and also lists the different reasons elderly people may have that cause sleep disturbances.
The cyclical process of sleep is moving through four phases, according to Hall, 1998 Rapid Eye Movement (REM) being the most important of these. A person enters REM sleep every ninety to one hundred twenty minutes in their sleeping cycle depending on what article one may read. REM is where the brain processes the day’s events and the body heals. Interestingly this is also where the skeletal muscles of the body become paralyzed and the only functioning muscle is the pharyngeal ones holding the airway open. “A perso...

The article "Causes and consequences of sleep deprivation in hospitalized patients" written by Stephanie Pilkington is exploring the causes and consequences of sleep deprivation in hospitalized patients. The author provides a brilliant summary of factors that affect the level of sleep experienced by patients in hospitals and the effects of sleep deprivation on the health and the wellbeing of these individuals. The article goes on to state that for sleep-deprived patients, there were bio-cognitive consequences for their health and recovery, with particular effects on immune functioning, inflammation, parasympathetic equilibrium, carbohydrate metabolism and cognitive performance.
Chronic sleep loss is becoming more common in modern culture and less restricted to sleep-deprived diseases such as insomnia. Suggested to be the result of a number car, industrial, medical, and other occupational accidents, sleep deprivation is beginning to be recognized as a public concern. As a result, the Centers for Disease Control

When most people think of sleep, they think of it as a relaxed but yet not a very important part of our daily lives. What most people don’t understand is although we are not up and moving around and getting tasks completed, our brains are still very active. Without sleep our bodies do not function correctly on a daily basis, and our mental state is at risk.

Based on the 5 studies above, a modest observation is seen between sleep deprivation and CVD. These study findings are of clinical importance as they suggest the probable usage of sleep duration as an additional risk marker for prevalence of CVD, regardless of ethnicity. Although implication of short sleep duration on CVD is consistent in various populations, it still differs within gender, age groups and race. Future research, using current studies as a framework, is needed to further prove the complex mechanisms underlying the causal relationship between sleep deprivation and CVD. Health authorities should also continuously promote the importance of adequate sleep as it is vital for better physical health and cognitive functioning.
Health is a complex concept, and when we talk about health we refer to body health and to the health of the mind, the health of relationships between us and those around us, the spiritual health. Looking online on one of the additional resources recommended, www.nimh.nih.gov, I have noticed that one of the symptoms of most diseases that affect a person's mental health is lack of sleep. Lack of sleep not only worsens man's mental health, but also causes serious imbalances in metabolism, immunity, general mood, and last but not least, affects the ability of learning and memorizing among students. The sleep fulfills a number of vital functions for both our mind and body. We spend about a third of our lives sleeping, which is a valuable and useful
According to (Miller, 2009), dementia is the most accurate expression which illustrates the development of cognitive impairment. ¬¬¬¬¬¬¬¬¬¬It exemplifies the diverse brain anarchies which ultimately lead to severe brain dysfunction (Alzheimer Australia, 2011). Dementia is the leading cause of disability in older adults in Australia accounting for 17 percent of the cases (Australian Institute of Health and Welfare, 2004). Alzheimer’s disease (AD), Vascular Dementia (VD), Frontotemporal Dementia (FD) and Dementia with Lewy Bodies (DLB) are the well known forms of this disease. This usually occurs in older adults aged above 65; however it is a disability and not a normal symptom of aging. Chances of inheritability are present but it depends on the individual and the type of dementia (Alzheimer Australia, 2011). The Global Deterioration Scale provides a detailed explanation regarding the seven stages of cognitive decline in Dementia (Alzheimer’s Association of Canada, 2005).
The authors and scientists from a different study by the U.S National Library of Medicine National Institutes of Health on long and short-term sleep deprivation state directly that “in certain jobs, people face sleep restriction. Some professions such as health care… require working at night. In such fields, the effect of acute total sleep deprivation (SD) on performance is crucial” (Alhola & Polo-Kantola, Sleep deprivation: Impact on cognitive performance). Depending on their schedule, nurses can often be susceptible to sleep deprivation and are no exception, especially if they are working long hours. The study performed research on how acute and chronic sleep deprivation can affect the brain and how it can slow down or worsen thought process and rationality throughout the day for working adults. The authors also explain that “motor function, rhythm, receptive and expressive speech, and memory ...deteriorated after one night of SD.” (Alhola and Polo-Kantola, Sleep deprivation: Impact on cognitive performance) Although everybody is affected by a lack of sleep differently, some might have the ability to handle it a lot better than others, but it is fair to say that no one can perform their jobs perfectly if their brains are being affected by sleep deprivation. This organization concludes this study by explaining that there is still much research that needs to be
Sleep deprivation is a commonplace occurrence in modern culture. Every day there seems to be twice as much work and half as much time to complete it in. This results in either extended periods of wakefulness or a decrease in sleep over an extended period of time. While some people may like to believe that they can train their bodies to not require as much sleep as they once did this belief is false (1). Sleep is needed to regenerate certain parts of the body, especially the brain, so that it may continue to function optimally. After periods of extended wakefulness or reduced sleep neurons may begin to malfunction, visibly effecting a person's behavior. Some organs, such as muscles, are able to regenerate even when a person is not sleeping so long as they are resting. This could involve lying awake but relaxed within a quite environment. Even though cognitive functions might not seem necessary in this scenario the brain, especially the cerebral cortex, is not able to rest but rather remains semi-alert in a state of "quiet readiness" (2). Certain stages of sleep are needed for the regeneration of neurons within the cerebral cortex while other stages of sleep seem to be used for forming new memories and generating new synaptic connections. The effects of sleep deprivation on behavior have been tested with relation to the presence of activity in different sections of the cerebral cortex.
Sleeping is something that is an essential part of human nature and is a must in order for one to be a functional human being. Sleep is an idea that is accompanied by many wives’ tales, including the ideas that one needs seven to eight hours of sleep each night and alcohol helps one fall asleep and sleep more soundly. One myth about sleep is that during sleeping, one is in a state of nothingness. In truth, however, it has been discovered that during sleep the brain is active, variations in heartbeat and breathing occur, and the eyes and ears are active throughout the time of sleep. These activities during a person’s sleep are important because they help that person be more aware, awake, and alert during consciousness. If all of these important activities occur during sleep, why is it that people are so willing to short themselves of this vital activity? Although much about sleep still remains a mystery, research and experiments continue to show how important sleep is to each and every person. Throughout this paper, I will discuss sleep and the effects that it has on performance and health, especially in college students. A college student’s sleeping pattern is a reliable indicator to their level of performance in the classroom and other school-affiliated activities, as a lack of sleep leads to decreased performance. Sleep is directly related the level of performance and health in an individual; the more rested a person is, the better that person will perform and feel (Dryer, 2006).
Sleep is a very important factor in the human function. Our body and brain is able to reset itself and rejuvenate while we sleep. When we do not get the required amount of sleep, we start to feel lethargic and foggy minded, because our mind and body wasn’t able to replenish itself. Sleep is imperative that an insignificant rest deficiency or lack of sleep can affect our ability to remember things; decisions and can affect our temperament. Chronic sleep deficiency can get the body to feel agitated and it could lead to serious health problems such as, heart problems, stress, acne, and obesity.
