The following paper focuses on Alzheimer’s disease, the disease which is a devastating brain disease and is one of the most typical forms of dementia, a general term that is most commonly used for memory loss and the diminishing in mental and physical abilities. It is most frequently diagnosed in the elderly although there have been some cases of the disease affecting people of middle age. There is not one known single cause for Alzheimer's, however, scientists believe that due to the structural and chemical changes in the brain eventually gradually destroy brain cells thus effecting reasoning, learning and memory. If it continues to advance, the result is body failure. The disease affects the body in different stages, and as the stages become higher the symptoms become worse. Though the disease is incurable there are medications that can keep symptoms under control, and help the individual maintain a regular lifestyle.
The overall purpose is to provide an explanation of Alzheimer’s disease and its stages. Alzheimer’s disease affects the elderly, and in some rare cases individuals that are in their middle ages. The disease’s severity is diagnosed by stages. The higher the stage the worse the symptoms can be. In the first stages, friends and family members might notice changes in behavior, mood and communication patterns. Most common signs of the first stage include forgetting events and social withdrawal and forgetting where things are placed. During the middle stages of Alzheimer's, the main sign is being unable to perform daily task and needing assistance. A person in this stage has decreased judgment and skills in maintaining good hygiene. The individual’s memory will become worse. However, they can recall their own name, but may have trouble remembering family members and can become disoriented. The main symptom, which occurs in, the late stages of Alzheimer’s, is severe personality and behavior changes. According to the Alzheimer’s Research Foundation, “Cognitive function are accompanied by changes in the brain, including the build-up of amyloid plaques and tau-containing neurofibrillary tangles, which result in the death of brain cells and the breakdown of the connections between them.” When the severity of the disease reaches its maximum potential the brain deteriorates, as well as, the body until it is unable to function any longer. Stages 1-3
Studies have demonstrated that the pathological processes of the disease are present in the brain for years before the appearance of symptoms (e.g., Bennett et al., 2006; Morris et al., 1996; Petersen, 2004; Price et al., 2009; Rubin et al., 1998; Storandt, 2008) indicating that early symptoms of the disease are likely to be present in some adults who appear to be normal. Doctors and Researchers have diagnosed the disease with having 7 stages. Throughout the first stage, individuals are still what appear to be normal. They are able to do normal task with no difficulties at all. In the stages 2-3, the individual may begin to realize that they are having issues with their memory. This is especially more apparent with recent memories. The hypothalamus, which is part of the brain responsible for changing experiences into memories, is the first part of the brain attacked by Alzheimer's disease. In this stage, words become unfamiliar and difficult to recall, and items get misplaced frequently. According to Alzheimer’s Disease Research Foundation,” there is an overall shrinkage of brain tissue. The grooves or furrows in the brain, called sulci (plural of sulcus), are noticeably widened and there is shrinkage of the gyri (plural of gyrus), the well-developed folds of the brain's outer layer. In addition, the ventricles, or chambers within the brain that contain cerebrospinal fluid, are noticeably enlarged.” As you continue to age, the disease changes your brain’s regular patterns and forming.
Within stages 4-5 the symptoms become...
