Less commonly, a non-degenerative condition may have secondary effects on brain cells, which may or may not be reversible if the condition is treated. The causes of dementia depend on the age at which symptoms begin. In the elderly population, a large majority of cases of dementia are caused by Alzheimer's disease, vascular dementia or both. It is rare to have dementia in young people 1.2 Describe the types of memory impairment commonly experienced by individuals with dementia. The memory impairment may result in lack of attention, forgetting language, forgetting names and identity of friends and relatives and lose of ability to solve problems.
Alzheimer’s disease accounts for 60% to 80% of cases. Vascular dementia; this is the second most common form of dementia after Alzheimer’s. It is caused by problems in the supply of blood to the brain, which usually occurs after a stroke. Vascular dementia also occurs because of brain injury or a blood vessel blockage to the brain. Parkinson’s disease; the brain changes caused by Parkinson’s disease begin in a region that plays a key role in movement.
Alzheimer’s disease By: Sheryl Powers D1MA101011 January 16 2012 Alzheimer’s disease is a slowly progressive disease of the brain that is believed to be cause by an increase of beta-amyloidal protein, which leads to nerve cell death. The nerve damage in the brain affects memory, reasoning skills, language and also perception. Alzheimer’s is a form of dementia and is thought to be the most common cause for dementia in patients over the age of 60. Patients over the age of 70 are considered to be at higher risk, with Alzheimer’s affecting the lives of about 50% of elderly over the age of 85. Alzheimer’s findings can be dated back to the 1900’s.
Most experts believe they somehow block communication among nerve cells and disrupt activities that cells need to survive. Introduction Alzheimer’s disease is a brain disorder named for German physician Alois Alzheimer, who first described it in 1906. Scientists have learned a great deal about Alzheimer’s disease in the century since Dr. Alzheimer first drew attention to it. Today we know that Alzheimer’s: * Is a progressive and fatal brain disease. As many as 5.3 million Americans are living with Alzheimer’s disease.
At Any Given Time, anyone can become vulnerable, the composition of the population has changed demographically and the elderly population has increased in recent years because of the development of the science and technology, but with this increment of the elderly population the vulnerability increases as well, due to some factors that this vulnerable population is exposed to, such as increase of the needs, physical and mental limitations, and lack of financial resources. Chronic illnesses increase vulnerability in elderly patients because patients become more dependent of assistance from family and require more medical care and health services to manage their physical limitations and disease. These most common diseases are: Alzheimer disease, heart disease, respiratory diseases, stroke, poor vision and hearing
This will also increase the amount of people that are retired from 12 percent of the United States population to almost 20 percent. With the rise of the aging population there is a need for more professional health and social service expertise. According to the Institute of Medicine’s landmark report, the is a shortage of health care professionals to care for the aging population in the current time and this number will grow faster as the Baby Boomers retire. One of the fastest growing employment sectors would be the eldercare. .
Disease Trends and the Delivery of Healthcare Services Disease Trends and the Delivery of Healthcare Services The United States population is increasing in age because of the increasing infertility rates, and also people are living longer these days. There has been a 20 year increase in the average life span since the second half of the 20th century. We are often left with questions such as where does that leave my children and I in the future? How will this impact health care services? Aging Trend The United States population is increasing in age because of the increasing infertility
An ischemic stroke is usually characterized by a reduction or obstruction of blood supply to the brain due to blocked blood vessels caused by atherosclerosis or a blood clot. Up to twelve percent of ischemic strokes often cause death within thirty days and is among the largest health burdens in developed countries. It is worth noting that the epidemiology of stroke has been changing because of several factors, with the most important being an ageing population, as well as advancements in the treatment of the condition. Stroke prevalence is projected to increase globally as the population of individuals aged above sixty-five years augments (Ovbiagele et al., 2013, p. 2363). Ovbiagele et al.
Aging populations also bring on new patterns of work and retirement. People will spend more time in retirement which will strain our existing health and pension programs. On top of it, currently 80% of older Americans are living with one chronic condition, and 50% with at least two. Among Americans, close to 95% of healthcare expenditure is for treating chronic illnesses, which answers why the cost of providing care for people of age 65 or older is three to five times more expensive than that of someone younger than
Demographic Paper Becky Perez HCS/490 November 6, 2011 Kathy Loy The aging population today has grown considerably according to the aging statics given by USA.gov, 2011. “The older population has grown, which includes persons 65 years or older, and has reached 39.6 million in 2009” (USA.gov, 2011, p. 1). The older population represents 12.9% of the United States population and by the year 2030 will average 72.1 million. There were 64, 024 person who aged 100 years or more in 2009, (p. 1) and this growth in population can become a problem for the health care market. The United States has had the most spending for health care for persons age 65 and older (CDC.gov, 2011).
