Background: Alzheimer’s disease is a fatal neurodegenerative disease that becomes more prevalent with age. Discovered by German psychologist Alois Alzheimer in 1906, it is associated with a memory loss, speech impediment, and dementia. In Canada alone, 500,000 people suffer from this terrible disease and the number of cases is predicted to double by 2031[7]. Worldwide, nearly 44 million people are believed to be experiencing Alzheimer’s disease and every 68 seconds, someone in the United States of America develops Alzheimer’s [8]. Alzheimer’s disease is also the sixth leading cause of death in North America. Furthermore, it is the only leading cause of death that is still increasing in prevalence. Not only fatal, Alzheimer’s is also severely crippling for all the friends and family that are affected by the patient. The memory loss and dementia that is directly linked to Alzheimer’s disease can cause the patient to forget the identity of their loved ones. For the people that have known the patient for many years, this can be very devastating. The long and terrible journey from an able-bodied and functioning member of society to a barely self-sufficient person is not a pleasant one. Undoubtedly, Alzheimer’s disease needs to be cured not only for those suffering from the affliction, but for their loved ones who have to endure the fateful journey as well. Stages of Alzheimer’s: Alzheimer’s disease progresses at a very slow rate. Changes in the brain may begin to develop as much as twenty years before diagnosis [2] (Figure 1a). Mild to moderate Alzheimer’s (Figure 1b) may last two to ten years [2]. In this stage, there is very mild cognitive impairment including memory lapses in association with familiar words or location of objects... ... middle of paper ... ...neurons. As a result, many of the functions most humans take for granted such as eating, dressing, and remembering names is lost to those whose brain is impeded by the beta-amyloid plaques. Conclusion: Alzheimer’s is a terrible disease, the diagnosis of which marks a long and painful journey through neurofibrillary degeneration. Unfortunately, there are so many factors that lead to and expedite the disease that synthesizing a cure is no simple task by any means. Whether the cause of the disease is hyperphosphorylation of tau or beta-amyloid plaques, current medical technology can only delay the symptoms. Hopefully the future of medical research will yield a method for reversing the progression of the neurological degeneration because far too many victims and their friends and family are forced to embark on the long and painful journey of Alzheimer’s.
Think about it, an average teen in this world has just been diagnosed with a type of incurable dementia which will forever change his or her life. Frontotemporal dementia (FTD) is one of the less common forms of dementia. It is when the nerve cells in the frontal lobe die and over time the brain tissue shrinks. Frontotemporal dementia is mostly found in people who are in their teens or twenties. It can affect young people in a very negative way. They start to get aggressive and as the disease gets worse they lose friends and have a difficult time in school and understanding things. Frontotemporal dementia is a rare disease that is on the rise and affects the people of the younger generation.
Clinically, Alzheimer’s disease is characterized by the accumulation of beta-amyloid plaque between living neurons in the brain (Sabbagh, 2008). This results in an excessive calcium influx inside the neurons and the breakdown of a protein called tau. Normally, the rol...
Dementia is a significant health issue in Australia (Australian Institute of Health and Welfare 2012) (AIHW 2012). Whilst Dementia primarily affects older members of the community, it can also affect young people and has a significant influence on overall health and quality of life (AIHW 2012). The type of Dementia is a determinant in the severity and development of symptoms in individuals (Department of Health 2013) (DoH, 2013). The gradual, progressive and irreversible nature of Dementia has a considerable social and physical impact not only on the individual, but also on family and friends.
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.
People with dementia may have problems with short-term memory, keeping track of their belongings, keeping up with plans, remembering appointments or travel dates. Many dementias are progressive. This means that symptoms start out slowly and gradually get worse with time. Alzheimer’s and other types of dementia are diagnosed based on careful medical history, a physical examination, laboratory tests, and the characteristic changes in thinking, day-to-day function and behavior related to each
While there is little difference between dementia and Alzheimer it is important to distinguish the two. Dementia is, “ a general term for a decline in mental ability severe enough to interfere with daily life” (Alzheimer Association, 2014). While Alzheimer is, “is a ...
Disease is so persistent, disabling, and costly. Based on postmortem examinations of remaining brain tissues in Alzheimer’s patients, Amyloid plaques, and neurofibrillary tangles are the two main characteristics involved with Alzheimer’s disease. (5) Amyloid-B is a protein that accumulates on the inside and outside of neurons. High levels of amyloid proteins damage axons and dendrites. (3) These damaged axons and dendrites cluster into structures called amyloid plaques, which begin to form before any behavioral symptoms appear (3). As the plaques accumulate, the cerebral cortex, hippocampus, and other areas atrophy or waste away (3). In addition to amyloid-B, these neurofibrillary tangles accumulate from tau proteins (3). Tau proteins are the intracellular support structure for neurons. Tau proteins help assemble and maintain microtubules that transport nutrients along axons (5). However, in Alzheimer’s disease, tau undergoes changes that cause it to bind to itself, resulting in neurofibrillary tangles (5). Therefore, the combination of amyloid and tau produces the behavioral deficits seen in those who suffer from Alzheimer’s disease ...
In this day and age, it seems as though almost everyone has experience a loved one taken away form a very serious disease known as Alzheimer’s disease. Alzheimer’s disease is unbelievably devastating for everyone affected by it. This disease is causing major economical problems such as less occupancy in the nursing homes, and hospitals due to the rising population of elderly men and women being diagnosed with it everyday. Because there is not yet a cure for this disease and the percent of the population being diagnosed keeps rapidly rising, more time and money needs to go towards Alzheimer’s research.
Alzheimer's disease is a neurological disorder which kills the brain cells, causing memory loss and cognitive decline. This leads to severe psychological impairments which changes how people think, behave and other complications such as paranoia, disorientation and unprovoked aggression. These psychological impairments reduce people’s functional ability and therefore reduce their quality of life.
In the field of Psychology you can find an abundance of mental disorders that can have an affect on people all throughout the world. Out of all the mental disorders that can be found around the world, some of them are more well-known and more widespread than others. The following disorders could be described as being well-known and widespread disorders: depression, bi-polar disorder, Alzheimer's, and OCD, which could also be called Obsessive Compulsive Disorder. All of these mental disorders can be very dangerous and possibly deadly if people don't receive the proper care in order to be able to contain these disorders. Out of these very dangerous and possibly deadly disorders, I believe that Alzheimer's is the most interesting disorder. I think that Alzheimer's is the most interesting disorder, because I think we have the least about of knowledge of the Alzheimer's disorder. As a society we still to this day don't have a cure that totally stops this disorder.
Alzheimer’s disease (AD) is one of the leading causes of death in America and there are currently more than five million people living with the disease (Alzheimer’s Association, 2014). What may be most troubling about these numbers is the fact that Alzheimer’s disease has no current cure. Alzheimer’s disease is a neurocognitive disorder and a common form of dementia that will affects a person’s memory, way of thinking and their behavior (Alzheimer’s Association, 2014). AD typically develops slowly and the more time a person has the disease the worse the symptoms will become. AD in its later stages becomes so severe that people with the disease cannot even do simple daily tasks. Although there is no cure there are still ways to prevent, delay, and possibly treat the disease.
Alzheimer's disease is the most common form of dementia, and this terminal, progressive brain disorder has no known cause or cure. Its greatest known risk factor is increasing age which is why is it is infamous for developing in the elderly, typically in ages 65 or over, however for the 5%(1) that develop Alzheimer’s in their 40s or 50s it is known as early Alzheimer’s. Because Alzheimer’s worsens over time, those with it tend to struggle with completing daily tasks especially elderly people. Given that there is no cure for Alzheimer’s, the treatments available slow the worsening of dementia symptoms and improve quality of life for those with Alzheimer’s and their caregivers. It is not known what causes Alzheimer's, however, those with Alzheimer's have been found to have abnormal amounts of protein (amyloid plaques) and fibres.(The amyloid plaques and fibres are found in regions of the brain where problem solving and thinking take place e.g The cerebrum.) Due to the unusual amounts of amyloid plaques and fibres, it reduces the effectiveness of healthy neurons and eventually, destroying them.
In 1906, a German physician named Dr. Alois Alzheimer dealt with a patient that had been battling severe memory and confusion problems and had tremendous difficulty understanding questions and basic functions. Alzheimer suspected that the ailment had more to it than inherent memory loss. During an autopsy of the brain, he discovered that there were deposits of neuritic plaques surrounding the nerve cells and twisted fibers, known as neurofibrillary tangles, inside of the nerve cells. These observations became the definitive diagnosis of Alzheimer’s disease. The plaques and tangles that develop are a natural part of aging; however, they develop far more aggressively in Alzheimer’s victims. The plaques and tangles then block communication among nerve cells and disrupt the cells processes, eventually killing them. This destruction causes memory failure, personality changes, and problems carrying out everyday functions. Alzheimer’s especially attacks the memory. A victim in the later stage of the disease can...
The elderly represents a large amount of the population in our society and continues to grow each day. As the population grows, it is important to meet the demands and resolve the challenges that we encounter in regards to the overall quality of health and well-being of the elderly. Mental health of the elderly is a major issue but majority of the time goes unnoticed and untreated by caregivers and loved ones. About 20 percent of adults 55 and older are suffering from some type of mental health disorder, and one in three elderly adults do not receive any type of treatment (The State of Mental Health, 2008). Those suffering from mental illness are hesitant to seek out help or any type of treatment because of the stigma, services and cost for care that then comes with mental health disorders. Mental health issues that affect elderly include dementia, delirium, and psychosis. Some of the most common conditions include anxiety, mood disorders such as depression and bipolar disorder and cognitive impairment such as Alzheimer’s disease. Mental health is essential to the
This paper is on dementia, a late-life disorder, as it pertains to the geriatric population. “It is estimated that 24.3 million people around the world have dementia and that, with an estimated 4.6 million new cases every year, we can expect about 43 million people and their families to have to handle the challenge of dementia by 2020.” (McNamera, 2011) I will cover three relevant points concerning this disorder that cause changes in the brain.
