Alzheimers disease Essay -- Alzheimers Disease Essays

Alzheimers DiseaseAlzheimers disease is a form of dementia, a outlook overturn that seriously affects a persons ability to carry out daily activities (Shenk 14). Alzheimers is a progressive and irreversible brain disorder that slowly destroys a persons memory and ability to learn, make judgments, communicate, and accomplish daily activities. As Alzheimers progresses, individuals may also experience changes in personality and behavior, such as anxiety, suspiciousness or aggravation, as well as illusions or hallucinations. Alzheimers disease is named after a German doctor, Dr. Alois Alzheimer. In 1906, Dr. Alzheimer became aw ar of changes in the brain tissue of a woman who had died of an unusual mental illness. Dr. Alzheimer found irregular clusters and tangled bundles of fibers. Today, these plaques and tangles in the brain ar considered signs of Alzheimers (Shenk 12-14). Scientists have also found former(a) brain changes in plurality with Alzheimers. Nerve cells die in areas o f the brain that are vital to memory and other mental abilities. There also are lower levels of some of the chemicals in the brain that carry messages back and forth between nerve cells. Although many things are known about Alzheimers, there are still many things that remain a mystery, such as causes, and how to cure Alzheimers.Alzheimers disease affects the brain cells which are called nerve cells. Neurons send messages from one to another, which allows us to think, remember and speak. In each of the neurons there is a branch like structure. Some carry impulses away from neurons (afferent), and some fill impulses to the neurons (efferent). The relaying of impulses from neuron to neuron in the brain makes it possible for one to carry out physical and mental tasks. When plaques and tangles form in the brain, they disrupt the flow of messages to the neurons. This happens when people age, but with an Alzheimers patient there are many more than that disrupt, which allows them to forge t simple tasks. Plaques are abnormally sticky clusters of protein. They disrupt pathways that carry signals from neuron to neuron. Plaque is a deposit of protein mixed with fragments of dead or dying neurons found in the brains of patient who have Alzheimers. A tangle is a counterbalance of twisted nerve cell fibers found in the cell bodies of neurons in the brains of the patients who ha... ...urrently incurable, and only two drugs--tacrine (Cognex) and donepezil hydrochloride (Aricept)-- have been approved by the FDA for its treatment. Several other drugs are being prescribed more often as their benefits are demonstrated in wider testing. Nonetheless, the mainstay of treatment for a person with Alazheimers continues to be grave nursing care, providing both physical and emotional support for a person who is gradually able to do less and less for himself, and whose behavior is becoming more and more erratic. Modifications of the home to increase safety and security are often neces sary. The caregiver also needs support to prevent anger, despair, and burnout from becoming overwhelming. Becoming beaten(prenominal) with the issues likely to lie ahead, and considering the appropriate financial and legal issues early on, eject help both the patient and family cope with the difficult process of the disease. Regular health check care by a practitioner with a non-defeatist attitude toward Alzheimers is important so that illnesses such as urinary or respiratory infections can be diagnosed and treated properly, rather than being incorrectly attributed to the inevitable decline seen in Alzheimers.
