In old age you may forget a few things here and there, but it is only when the symptoms affect the person’s daily life that it can be called Dementia. The exact cause of Dementia is damage to the brain cells; it affects the way the brain cells are able to communicate with one another. When the cells aren’t able to communicate, it commonly disturbs thinking, behavior, and feelings. Synapse or neuron to neuron functioning is dismal which results in confusion and communication problems. Many things can cause damage to the brain cells such as, diseases that cause deterioration in the brain like Alzheimer’s and Parkinson’s.
Alzheimer’s disease Holly Salyards Cincinnati State Technical & Community College Alzheimer’s disease is a progressive brain disease which slowly destroys thinking and memory skills. These changes are severe enough to interfere with day to day life. This irreversible disease is the most common cause of dementia amongst the elderly, with an appearance of first symptoms after age 60. In 1906, Dr. Alois Alzheimer, noticed some changes in the brain tissue of a woman who had died of an unusual mental illness. Her symptoms were comprised of memory loss, language problems, and unpredictable behavior.
Dementia and Delirium are perplexing conditions both to differentiate and experience. Dementia is a progressive intellectual function and other cognitive skills decline condition which results to a decline in an individual’s performance of their daily activities. Unlike dementia, delirium also known as acute confusional state is an acute medical condition which results in confusion and other disruptions in a person’s thinking and behavior including attention, activity level and perception. It is very important to distinguish between the two conditions because, delirium can be found in a person that already has dementia. A study done by Fick and Mion (2008) indicated that, about 22% of adults with dementia develop delirium.
It is said that memory declines as people age, and this can be just a natural part of life. However, in many cases as people grow older, they develop a mental disorder known as Alzheimer’s disease. Alzheimer’s is a disease that causes problems with memory, thinking, and overall behavior, and progressively becomes a bigger problem. Alzheimer’s is the most common form of dementia and is a very common disease in people over the age of 65. This terminal disease puts tremendous stress on the victim and the victim’s family.
Introduction Alzheimer’s is a disease that effects older people’s brains. It is usually not a part of aging. A long time ago, people would call memory loss hardening of the arteries. This paper talks more about Alzheimer’s, signs and symptoms, has the causes, treatment, and diagnosis. Description Alzheimer’s is a disease which makes people lose memory.
One of the major illnesses that are effecting our elderly population is the illness of dementia, or cognitive impairment. According to the Webster dictionary dementia is “a mental illness that causes someone to be unable to think clearly or to understand what is real and what is not real”. In reality dementia is so much more than this, it is more clearly defined on the Alzheimer’s Association website, “ Dementia is not a specific disease. It’s an overall term that describes a wide range of symptoms associated with a decline in memory or other thinking skills severe enough to reduce a person’s ability to perform everyday activities”. Dementia is most commonly seen in those who are over the age of 60, and the older a person gets the higher their risk of developing dementia becomes.
Dementia worldwide is a common cause of death for the elderly. Dementia is a syndrome – usually of a chronic or progressive nature – in which there is deterioration in cognitive function beyond what might be expected from normal ageing. (WHO). Dementia can affect many things from memory, thinking, orientation, comprehension, and calculation, learning capacity, language and even judgment. ““Dementia” is an umbrella term describing a variety of diseases and conditions that develop when nerve cells in the brain die or no longer function normally.
Alzheimer’s Disease Alzheimer’s disease is a form of dementia, “a brain disorder that seriously affects a person’s ability to carry out daily activities (Shenk 14)”. Alzheimer’s is a progressive and irreversible brain disorder that slowly destroys a person’s memory and ability to learn, make judgments, communicate, and accomplish daily activities. As Alzheimer’s progresses, individuals may also experience changes in personality and behavior, such as anxiety, suspiciousness or aggravation, as well as illusions or hallucinations. Alzheimer’s disease is named after a German doctor, Dr. Alois Alzheimer. In 1906, Dr. Alzheimer became aware of changes in the brain tissue of a woman who had died of an unusual mental illness.
Neurological Etiology Mild cognitive impairment (MCI) or mild memory loss is a neurological disorder that develops due to deterioration of the normal cognitive capability of a person during the aging process. Mild Cognitive Impairment (MCI) can be defined as a condition where an individual suffers a decline in his/her cognitive abilities beyond the expected in normal aging. However, it is important to understand that these abilities are not obviously identified in daily living activities. It is considered to be an intermediate condition between decline in memory in normal aging and severe memory loss, such as dementia. Nonetheless, MCI has also been closely associated with dementia, as it is seen as a progression towards it (Petersen, 2004).
Alzheimer’s disease (AD) is a severe, incurable form of dementia that causes impairment and cognitive deficits such as language, speech, memory and basic motor skills (Buckley, 2011). Currently in the United States, there are 5.2 million individuals living with AD (Alzheimer’s Association, 2013). AD is a deterioration of one’s cognitive functions that prevents the ability for daily function and unfortunately has no known cure or preventative methods (Buckley, 2011).The main deficit that AD has on the brain is the deterioration of different areas of the brain. Not only does a physical toll contribute to patients with AD, but there is also a social stigma that impedes on the normal daily function of life. In this literature review, I will discuss the different effects that AD has on the brain and the outcome of what various repercussions can occur.
