Where is the cure for Alzheimer’s disease?

The most common form of dementia is, Alzheimer’s disease (AD). Alzheimer’s can be defined as a disease that includes memory loss and inabilities that affect daily life. A common misconception is that aging comes with Alzheimer’s. Although majority people affected with this disease are 65 and above, there is also a 5% of people who are in their 40s or 50s affected by Alzheimer’s. AD is a disease of progression. There are three stages of AD and by the third stage one affected loses the ability to converse. Alzheimer’s is the sixth leading cause of death in the United States (Overview | Alzheimer 's Association). Once a person is diagnosed with AD they can live for an additional four to twenty years

AD consists of three stages. The first stage known as the on-set or early stage, a person is still independently functional with a few memory lapses. Conversing may become difficult for the person and work performance may slowly deteriorate which leads to new changes in behavior. This stage can last up to five years. The second stage, known as the progressive or moderate stage, is typically the longest stage and can last for many years. At this stage the person diagnosed with Alzheimer’s will become more dependent on a caregiver. The symptoms of the first stage become more obvious, along with agitation caused by constant confusion. The nerve cells in the brain slowly deteriorate causing difficulty to express thoughts or perform daily routine. The last stage known as the late-stage, the individual loses their ability to respond to their environment. Communicating becomes nearly impossible and memory and cognitive skills worsen. By the time an individual reaches the third stage they have lost both short and long-term memory and 24-hour assistance becomes necessary. Because they become inactive their immune system weakens and increases the chance of disease or infection, which often times leads to death. (Alzheimer’s Disease …show more content…
The leading factor to cell death and tissue loss of a brain affected by Alzheimer’s is plaques and tangles. These dead nerve cells made up of another protein are known as tangles. In the areas where tangles are formed nutrients and other necessities can no longer move through the cells. This causes a build up of a protein, beta-amyloid, between nerve cells known as plaques. . (Alzheimer’s Disease Genetics) These clumps of beta-amyloid block communication amongst other cells sometimes leading to inflammation of the brain. The tangles consist of a protein called tau. Tau allows food molecules to travel along “tracks”. When tangles are formed the “tracks” no longer remain straight and fall apart and disintegrate. This causes the depletion of the cortex, which eventually leads to death. (Dimitrios

    In individuals which have progressed to a severe stages of Alzheimer’s disease, they can find themselves unable to recall their own history, difficulty communicating, and are vulnerable to infections such as; pneumonia. These stages of Alzheimer’s disease correlate to the amount of cellular damage to areas of the brain which control the particular cognitive functions such as; emotions, memory and coordination etc. Alzheimer’s disease effects the brain in different ways but the causative factor is brain atrophy, research by (Thompson et al., 2003) showed a grey matter decrease of ~2.3% in Alzheimer’s patients per year, compared to 0.9% of the control. This brain atrophy can be seen by eye, brain gyri become narrower and sulci grooves between the gyri become wider. The ventricles increase in size as they contain more cerebrospinal fluid to counter the brain size loss, seen in…

    At the time that it was first documented, it was thought to be a rare disease. Dr. Alzheimer found many amyloid plaques and neurofibrillary tangles in her brain upon investigation (“Alzheimer’s Disease Fact Sheet”). Currently, Alzheimer’s is the most common form of dementia, and it accounts for 60-80 percent of dementia cases. There is a current belief that damage to…

    Alzheimer’s disease is a progressive brain disorder that slowly destroys your ability to think and your ability to remember certain events. A person who has Alzheimer’s will eventually not be able to complete simple tasks. Currently, Alzheimer’s is the ranked as the sixth leading causes of death in the United States. Alzheimer’s is the most common cause of dementia. Dementia is the loss of cognitive functioning, which includes, thinking, remembering, and reasoning.…

    Alzheimer’s also causes the brain the shrink. “When doctors examine Alzheimer 's brain tissue under the microscope, they see two types of abnormalities: plaques and tangles. Plaques are clumps of a protein called beta-amyloid may damage and destroy brain cells in several ways, including interfering with cell-to-cell communication. Tangles occur because brain cells depend on an internal support and transport system to carry nutrients and other essential materials throughout their long extensions. This system requires the normal structure and functioning of a protein called tau” (Mayo Clinic Staff).…

    The cause of Alzheimer’s disease is when both amyloidplaque and tau build up, which contain neurofibrillary tangles and resulting in the death of brain cells and the connections between them. Around the nerve cell where there are dense deposits of protein build up, is known as plaque. Tangles are twisted fibres that build up in the cell. As the disease progresses the brain cells shrink and die. (Alzinfo, 2014) Vascular dementia is when there is damage to the blood vessels in the brain from a stroke and this impairs the cognitive function.…

    The amyloid plaque becomes embedded in the cell membrane. Once those plaques are on there, the plaque gets attached to the brain and is hard for it to be reversed; however this process can be slowed down. In a normal non-diseased brain, the tau proteins are functional, which stabilize the microtubules. In Alzheimer’s, the neurofilbrillary tangles become distortions of the tau proteins in the neurons, which become all tangled up and those microtubules lose their function (Mastroeni 2013). That then affects the person’s ability to function and work in life and it damages…

    This causes memory loss, behavioral issues and problems with critical thinking (Fact). Causes Amyloid plaques are essential when it comes to Alzheimer 's disease. Plaques are abnormal clusters of protein fibers between the nerve cells, as seen in Figure 1. They can be formed when pieces of a protein, also known as, beta-amyloid, begin to bundle together. The beta-amyloid are smaller pieces to a large protein that is found in the fatty membrane surrounding the nerve cells.…

    They will not be able to recognize their family and the surroundings they are familiar with. The definition of Alzheimer’s disease is “a progressive, irreversible brain disorder that is characterized by a gradual deterioration of memory, language, and eventually physical function.” Since women live longer than men do, they are the ones who are more likely to develop the disease. Researchers are stepping up their efforts to find the causes of Alzheimer’s and how to treat it. This disease triples the cost of health care for anyone 65 years and older. A protein called an Amyloid beta was found in the spinal fluid of individuals who have mild cognitive impairment and they developed Alzheimer’s disease within five years.…

    Plaques on the brain may cause some of the cells to die, as well as a tangle. Alzheimer 's is the leading cause of premature senility. There are three different forms of Alzheimer 's: Early-Onset Alzheimer 's, Late-Onset Alzheimer 's, and Familial Alzheimer 's Disease [FAD]. Now, two percent to five percent of people over the age of sixty-five have this disease. Twenty percent of people eighty years old have the disease.…

    This progressive disease happens in people who are 65 years old and older. Though it is thought to be a disease of old age, there is a small percentage of early onset AD in people who are only 30 to 60 years of age. According to the Alzheimer’s Association, Alzheimer’s disease in the sixth leading cause of death in the United States. After symptoms are noticeable, one can live an average of 8 years. Although survival can range from four to twenty years it mostly depends on their age and how bad their symptoms and health can be.…
