Brain Affected By Alzheimers Disease

Alzheimer's disease is a progressive neurodegenerative disorder of the brain that results in impairment of memory and reduction in the ability in reasoning, planning, language, and also perception.[3] It is considered as one of the most common types of dementia and it accounts for an estimated 60 to 80 percent of cases. This is due to the increasing number of deterioration of nerve cells in the brain. Thus, number of synapses decreases and causes the information transfer at the synapses begins to fail lead to cells die. [2] There are several risk factors in this case. Most experts agree that the greatest risk factor for Alzheimer's disease is advancing age but it is not a normal part of aging.[2]"The likelihood of having Alzheimer's disease increases substantially after the age of 70 and may affect around 50% of persons over the age of 85.

Nonetheless, Alzheimer's disease is not a normal part of aging and is not something that inevitably happens in later life. For example, many people live to over 100 years of age and never develop Alzheimer's disease."Medicine Net on Alzheimer's diseasehttp://www.medicinenet.com/alzheimers_disease/article.htm#tocc,retrieved on 3 September 2010Besides, it has been proven that Alzheimer's disease is caused by a combination of factors, including genetic inheritance, environmental factors, diet and overall general health meaning that no single cause for it. [7]There has no current cure for Alzheimer's disease and no proven treatment to slow its progression. However, treatments for symptoms can then be used to delay its onset. [5] Therefore, to overcome the increasing number of developing Alzheimer's disease, I have considered the use of cholinesterase inhibitors.
