Alzheimer disease - Research Paper Example Some symptoms include decline in memory and cognitive abilities of the affected individual. This paper will discuss the causes of Alzheimer, its prevalence, the risk factors, signs and symptoms of the disease. The paper will also look at the prevention and treatment options available to the affected people. Alzheimer’s disease Introduction Ballenger (2006) asserts that Alzheimer is the most common form of dementia that leads to memory loss and cognitive decline. Alzheimer is a neurological disorder associated with degeneration of brain cells among individuals aged 65 years and above. The gradual loss of brain cells results from tangles in nerve cells and beta-amyloid plaques that develop in the brain. Some risk factors that contribute to the disease include having a history of high blood pressure, trauma and stress. Ballenger (2006) asserts that â€Å"some symptoms of the disease as memory loss, impaired thinking, changes in personality and disorientation thus ultimately cont ributes to decline in cognitive functioning and damage of brain cells in the cerebral cortex, p 89. Medical scientists assert that Alzheimer is caused by a combination of lifestyle, genetic and environmental factors that impair the brain over time. However, less than 5 percent of the cases result from genetic changes. In the US, more than 5 million people aged 65 years and above are believed to be living with the disease. According to the 2013 statistical report of Alzheimer’s Association, one-tenth of the citizens aged 65 years and above suffer from the disease while one-third of the citizens aged 85 years and above are living with the disease. According to the Association, the disease accounts for over 60 percent of all cases of dementia (Morgan & Carrasquillo, 2013). Alzheimer disease statistics It is estimated than 5 million Americans of all ages are suffering from the disease with an approximately 200,000 under the age of 65 suffering from the disease. One-tenth of peopl e aged 65 years and above is suffering from the disease while one-third of the people aged more than 85 years old have Alzheimer’s disease (Morgan & Carrasquillo, 2013). The prevalence of the disease among women is high than in men since two-thirds of the individuals suffering from the disease are women (Morgan & Carrasquillo, 2013). The deaths attributed to the disease increased by 68 percent between 2000 and 2010 while those attributed to other heart-related diseases declined by 16 percent. The number of people living with Alzheimer is estimated to increase by 40 percent to 7.1 million by 2050 (Morgan & Carrasquillo, 2013). Currently, the disease is the sixth largest cause of death in the US. The causes of Alzheimer disease Alzheimer is a neurodegenerative disease that is caused by death of brain cells that happens over a long period of time. According to Dash and Villemarette-Pittman (2005), the postmortem or autopsies of victims of the disease often show tiny inclusions o f in the nerve tissue thus suggesting the disease leads to death of the brain cells. Genetic, environmental and lifestyle factors that lead to death of brain cells thus leading to memory loss and decline in cognitive functioning of the individual (Welsh, 2006). Risk factors One of the risk factors that lead to Alzheimer is family history and genetics of an individual. Risk genes and deterministic genes influence the likelihood of developing the disease (Welsh, 2006). The risk genes is the apolipoprotein E-e4
