The Global Population Is Ageing At An Alarming Rate

Alzheimer disease (AD) is the most common cause of dementia in the elderly, accounting for 65–70% of all cases (Jellinger, Janetzky, Attems, & Kienzl, 2008). The other dementias are of the Parkinson 's group, the fronto-temporal group and the vascular group. The total worldwide yearly costs for the treatment and care of patients suffering from dementia are estimated to be around 250 billion US dollars. The lifetime risk for AD between the ages of 65 and 100 is 33% for men and 45% for women with an annual increase of 1–2% in the seventh decade to almost 60% in the 10th decade with doubling every 5 years (Jellinger et al., 2008). AD is incurable, and thus represents a major public health problem. AD represents a challenge to humanity due to its relatively recent discovery, progressive nature of the illness, and complex diagnosis.

The disease called Alzheimer’s is the fourth leading cause of death in the United States (Weiner, 1987). It is estimated that the elderly population will double between now and 2030. During this period, the number of elderly will grow by an average of 2.8% annually (U.S. Census Bureau, 2001). By 2050, the number of people with Alzheimer’s is estimated to range from 11.3 million to 16 million (Alzheimer’s Association, 2005). These startling numbers should prompt an examination into one of the leading causes of death among this group of people. Understanding what Alzheimer’s is and the known causes of the disease are a good starting point. For those who have aging family members, knowing the risk factors and warning

Research conducted by the Australian government in 2011, estimated that 298,000 Australians have been diagnosed with dementia and based on current projections, this number will exceed 400,000 by 2020. (1) Although forecast methods vary, the number of people with dementia is expected to triple between 2011 and 2050 and is estimated to reach approximately 900,000 by 2050. (1)

Dementia can be defined as a decline in mental ability severe enough to interfere with daily life (alz.org). More than often, individuals affected by dementia are over the age of 65. In the United States, there are more than three million cases of dementia each year. According to World Health Organization, the number of people living with dementia is currently estimated at 47.5 million worldwide and is expected to increase to 75.6 million by 2030 (World Health Organization 2015). Dementia is caused by physical modifications in the brain and is known for loss of memory and mental abilities. It’s a progressive disease which means it gets worse over time. If diagnosed early on, the quality of life for people with dementia as well as their family members can be significantly improved. There are many different types of dementias although some are far more reciprocal than others. One of the most common types of dementia is Alzheimer’s disease. Other few types of dementias are “Vascular dementia, Mixed dementia, Parkinson 's disease and Frontotemporal dementia (Krishnan, D. S)”. All of the various forms of dementia tend to have similar symptoms which consequently makes it hard to determine the type of dementia a patient may be suffering from.

In the United States there are approximately 5.4 million people living with Alzheimer’s. Every sixty-nine seconds a person is diagnosed. This is an ongoing issue, and unless something is done, sixteen million people will be affected by 2050 (Latest).

By 2015, it is estimated that there will be a number of 850,000 dementia sufferers in the UK and about 225,000 people develop dementia every year in which it is roughly about one person in every three minutes. It is predicted that the number of people with dementia will exceed 2 million in 2050 if preventative measures are not taken. In brief, dementia can be described as a persistent and progressive loss of mental ability due to brain diseases or injuries in which the symptoms can be recognized by memory disorders, perception and personality changes and also impairments of body functions. Alzheimer is the most common type of dementia which contributes about 62% of the cause of dementia and had become a global prevalence disease. By 2015, it

Alzheimer’s disease is a complex illness that affects the brain tissue directly and undergoes gradual memory and behavioral changes which makes it difficult to diagnose. It is known to be the most common form of dementia and is irreversible. Over four million older Americans have Alzheimer’s, and that number is expected to triple in the next twenty years as more people live into their eighties and nineties. (Johnson, 1989). There is still no cure for Alzheimer’s but throughout the past few years a lot of progress has been made.

An estimated 47.5 million people suffer from dementia. Every 4 seconds one new case of dementia is diagnosed. Dementia is a term that describes certain symptoms such as impairment to memory, communication and thinking. It is a group of symptoms and not just one illness. Even though one‘s chance of getting dementia increase with age, it is not a part of aging. Dementia is usually diagnosed after a series of assessments that includes a physical evaluation, memory tests, imaging studies and blood work. It affects three aspects of one’s mental function, cognitive dysfunction (Problems with memory, language, thinking and problem solving), psychiatric behavior (changes in personality, emotional control, social behavior and delusions) and difficulties with daily living activities (driving, shopping, eating and dressing). “The median survival time in women is 4.6 years and in men 4.1 years” (Warren, 2016).

One of the most prominent and perhaps most feared condition associated with aging is dementia. The family of disorders can cause individuals to lose their mind, reducing one from being a complex, thinking, feeling human being to being confused and vegetative, unable to recognize their loved ones. Serious dementia affects nearly 37 million people globally, but predictions of how those numbers will change over the next few decades are conflicting (textbook). Although we know dementia as to do with damage to nerve cells in the brain, there are ongoing studies looking at correlations between other health issues and these types of diseases.

Dementia is a disease which causes mental debility and affects one’s way of intelligent, attentiveness, recollection and problem-solving (NHS, 2013). As a result of dysfunction of brain cells in some parts of the brain it affects the thinking process then dementia occurs and it usually comes with age (Ibid). It is estimated that 560

The incidence of dementia increases as the general population ages and one source estimates approximately two billion individuals being affected by the year 2050 (Vasionyte & Madison, 2013). The nature of dementia results in cognitive decline that may lead to inappropriate behaviors, such as aggression, agitation, mood disorders, and eating problems, which can be a severe impairment when treating these patients

It is also projected that this number is to rise to a nearly three times larger number, fourteen million by 2050. Often, the changes that the brain undergoes

Alzheimer's disease (AD, the most common form of dementia) accounts for 60% prevalence in LDCs (Kalaria et. al., 2008). A survey led by experts commissioned by Alzheimer's Disease International estimated that 24.3 million people suffered from dementia in 2005, and 4.6 million new cases were reported annually (Kalaria et. al., 2008). Projections by Alzheimer's Disease International and WHO propose that by 2050, 115 million people will be living with AD/ dementia globally, of which a growing proportion will reside in LDCs (approximately 55 million by 2020 according to WHO) (Kaneda, 2006). There is a common awareness about its final stages which comprise of: loss of reasoning, memory, speech, along with other cognitive functions. In most LDCs,

Synopsis: The ageing of the population has become on of the major talking points of modern economics and its implications for world growth in the future. This essay examines the causes of the demographic shift by focusing

We are living in the global society where our families are our major support. Our population is growing. We have already get used that people have few or many siblings or cousins and big families are not rare. However, it is unlikely to last long. The fact is that the number of youth among the global population is decreasing. Moreover, it did not start to decrease recently. As stated in the “Demography Is Not Destiny: The Challenges and Opportunities of Global Population Aging” the proportion between the young people and seniors has started to change since 1950s and is still changing now. It is predicted that in next forty years older people will become “more numerous than children”. (Uhlenberg 1) Those changes in the structure may have a negative impact on both societies and economies. It may be hard for people to adapt to an “updated” society as it changes so fast that they may not be ready to face it. (Lutz, Sanderson, Scherbov 2) It is predicted that by the end of this century people of age 80 will outnumber other age categories. (Geohive) It means that the number of people younger than 80 will either decrease or remain same. It is hard to predict the exact changes, but I feel like this is unlikely to happen. I think governments will somehow find a way to increase fertility. They may provide some benefits to families that raise more than two children, such as free or inexpensive houses and less taxation. It may help to support families, especially families with low
