Alzheimer’s disease or AD is an incurable disorder of the brain that results in loss of normal brain structure and function. In an AD brain, normal brain tissue is slowly replaced by structures called plaques and neurofibrillary tangles. The plaques represent a naturally occurring sticky protein called beta amyloid and in an Alzheimer’s brain, sufferer’s tend to accumulate too much of this protein. Neurofibrillary tangles represent collapsed tau proteins which, in a normal brain along with microtubules, form a skeleton that maintains the shape of the nerve cells. In Alzheimer’s disease, the tau proteins break loose from their normal location and form tangles. Without the support of these molecules, nerve cells collapse and die. As normal …show more content…
There are few people who do not worry about getting AD as they get older. Indeed, the incidence of AD increases with each successive year of life after age 60. Currently, scientists estimate that “4.5 million people have AD in America alone and 22 million worldwide” (Willett 63). The disease affects about “five percent of people ages 65 to 74 and nearly half the population of people 85 and older” (“Alzheimer” 1). Disturbingly, the disease is becoming even more common. Statistics now show that the number of people with the disease doubles every five years among older people. Using this as a rule, Dr. Robert Katzman of the University of California “estimates the total could be 45 million worldwide by 2050” (qted in Willett 13).
With these future projections of the incidence of AD, the financial cost of supporting the afflicted will be exorbitant as well. Lifetime societal costs for an individual afflicted with Alzheimer’s disease are “$174,000 in the United States” (Willett 13). The cost to businesses that “lose productivity of their employees who must care for their relatives afflicted with AD is 26 billion”(Willett 13). Economists also state, “the total cost to the United States per year for the care of AD patients is estimated to be 100 billion” (Willett 13). With these kind of costs financially, it is mandatory that public health programs be instated to decrease the
Alzheimer 's disease (AD) was discovered by a German doctor Alois Alzheimer in 1906 when he found amyloid plaques and neurofibrillary tangles in the autopsy of a woman who died of an unknown mental disease. The extracellular amyloid plaque deposits, composed of insoluble amyloid-Beta peptide were hypothesized to be the main etiological factor. “The most important abnormality is an excess of Amyloid-beta peptides brought about through either overproduction or failure in degradation.” (Uzun, Kozumplik, & Folnegović-Smalc, 2011) Later, it was discovered that intracellular neurofibrillary tangles composed of hyper-phosphorylated, helically-paired tau
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
Alzheimer’s Disease is a disease of the future. With the growing aged population, this disease, which affects primarily the elderly, will become of increasing relevance to the medical profession. Also, the high frequency of Alzheimer’s, and the high cost in labor, money, and material of caring for its victims shall put considerable burden on the society as a whole. Here, however, these issues are not going to be debated. Instead the pathology of Alzheimer’s will be reviewed to the extent it is known today.
Alzheimer’s Disease is an irreversible, genetically linked illness. This disease was chosen for the topic of this essay under the consideration that in many families the illness can be incredibly tragic, passing down for generations without mercy. It is not rare to encounter families in which each member is afflicted with a form, mild or severe, of Alzheimer’s. The disease is a progressive brain disease which comes in two separate types: Early-Onset Alzheimer’s Disease and Late-Onset Alzheimer’s Disease. These will be discussed in full later on in the paper.
get it, but most cases are the only ones in a family. Some patients who develop
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).
Those diagnosed with Alzheimer’s disease usually end up in nursing homes or hospice care centers, because, as the disease evolves to its later stages, the patient typically becomes unable to care for themselves and is required to have around-the-clock care. Nursing care is very expensive and can be estimated to cost “…approximately $47,000 per patient per year” (Cummings and Cole 1). Patients are plagued with not only memory loss, but also abnormalities of the motor system, problems assessing new information, trouble speaking and disorientation. “Patients with AD usually survive 7-10
A brain deteriorates, slowly being engulfed by a mysterious disease. The neurons being cut off and destroyed by two abnormal structures. First memory is affected gradually getting worse. Then one is unable to think properly, reason, and lacks of self control. Gaps are formed in the brain 's ventricles, due to the amount of dead tissue. In the end, it will lead to death. All of this may sound like something from a science fiction movie but infact its very real. These are all known possible symptoms of a common disease that affects about millions of Americans. It is known as Alzheimer 's disease (AD), and I plan on explaining it a bit more in this paper. First I will explain the disease and list some facts about it,then I will talk about some commonly asked questions about it.
Alzheimer’s disease (AD) is a form of dementia that causes problems with memory, thinking, and behavior. AD typically involves the development of a progressive neuropsychiatric disorder that is characterized by gradual memory impairment, loss of acquired skills and emotional disturbances (Lee, Y. J., Han, S. B., Nam, S. Y., Oh, K. W., & Hong, J. T.). Every 67 seconds an individual in the United States develops AD. AD is the sixth leading cause of death in the United States. There are 5.3 million Americans diagnosed with AD (Latest Alzheimer's Facts and Figures). AD is one of the few degenerative diseases that cannot be prevented, stopped, or cured (Latest Alzheimer's Facts and Figures). Post-mortem examination of the brain of AD patients usually
Alzheimer’s disease affects the lives of over 5 million Americans today. The cost that it has placed on the U.S is a staggering $203 million dollars. Researchers have reported that those numbers are expected to triple by 2050. However draining that this disease may seem, the real question is whether there is a solution. To this day there is still no cure to stop or even slow down th progression of the brain disease but there are treatments that help cover the symptoms. While the majority of the people who suffer from Alzheimer is generally over the age of 65, about 200,000, of the estimated 5 million, are in the age range of 30-40.
Health care needs become more challenging every day; in fact, it is one of the biggest problems the American economy faces today. However, within the next 20 years the population of adults ages sixty-five and older is expected to increase and “age is the key factor for development in later life” (Dilworth-Anderson, Pierre & Hilliard, 2012, p. 27). Recent studies have shown there are approximately 5.3 million Americans that have Alzheimer’s disease and it is expected to increase over
“Alzheimer’s disease is an irreversible, progressive brain disorder that slowly destroys memory and thinking skills, and eventually the ability to carry out the simplest tasks individuals with AD may start having symptoms their mid-60s” (nih.gov). AD is a multifactorial and progressive neurodegenerative disease. “Parts of AD, for example, increased oxidative state, amyloid plaque deposition, and neurofibrillary tangle of tau protein in the central cortex the limbic system of the brain, have been related with Alzheimer 's disease. The disease was once thought to be a natural part of aging; it is an extremely incapacitating type of mental dementia. Albeit, some dementia
The research into Alzheimer's Disease has come a long way since 1906 when it is was discovered by Alois Alzheimer. He detected microscopic brain tissue changes called senile and neuritic plaques in deceased patients. These are chemical deposits consisting of protein molecules called Amyloid Precursor Protein(APP) that are fundamental components of a normal brain. However in the brain of an Alzheimer patient, an enzyme cuts the APP apart and leaves fragments in the brain tissue. These combined with degenerating nerve cells cause the plaques or lesions. These lesions are found in many sections of the brain including the hippocampus which regulates emotion and memory, the basal forebrain, and especially the basal nucleus of Meynert and the cortex, where the memory function is located.(2) Another sign of a diseased brain are neurofibrillary tangles, which are malformations within nerve cells.
Although Alzheimer’s disease (henceforth: AD) has been around since the 19th century or possibly even earlier and was at a point in time classified as senile dementia, it wasn’t until 1906 following Dr. Alois Alzheimer’s encounter with Auguste Deter at a Frankfurt asylum that the name of the disease was finally coined. Since then, major developments relating to the disease has taken place. In our report, we addressed some of the areas of the history, contemporary and prospects of the disease.
Alzheimer is a disease that affects the elderly most. The disease was discovered by Dr. Alois Alzheimer in the year 1906 when he was examining a female’s brain. He found out that the woman displayed memory loss, language problems and some inexplicable changes in behavior. The disease was named after the doctor who was a German psychiatrist and a neuropathologist. Alzheimer’s disease is a degenerative brain disorder that leads to memory loss, personality changes, and language problems (Gilbert & Julie 2). The disease is mostly diagnosed in people over the age of 65 years, though there is a small minority of people under the age of 50 who get the disease. Studies show that 1% of a whole population aged between the ages 65-75 have severe
