Alzheimers - Research Paper ExampleDuring the autopsy the doctor noted dense deposits of neuritic plaques surrounding nerve cells and perverse bands of nerve fibers inside the cells. The presence of plaques and tangles during a originator autopsy is now taken as a definitive diagnosis of the condition. There have been some(prenominal) additional researches that have been carried out by scientist around the world since the discovery of the disease. In the 1960s researchers found connectivity between the cognitive decline and the number of plaques and tangles give up in the brain. Since the 1970s scientists have made major discoveries pertaining to the complex functioning of the nerve cells in these patients and also with increasing developments in the field of genetics, genes responsible for skill to this disease both in the early stages and later in life have also been unraveled. Apart from the genetic factors other lifestyle related and environmental risk factors are also being widely being explored (A History, 2009 Alzheimers disease, 2010).Alzheimers is a progressive disease and before the symptoms are noticed adequate damage to the brain would have already taken place. Studies reveal that this damage could occur anywhere between 10 to 20 years before the invasion of the clinical signs and symptoms. Beginning with the development of tangles within the entorhinal cortex and plaques in other regions of the brain, the disease affects the functioning of neurons that eventually results in lost communication between the brain cells. When such damage occurs within the hippocampus region of the brain as the disease progresses, it affects the memory and processing skills of the individual (Alzheimers disease, 2010). Thus most full-grown early sign of the disease is memory loss (Alzheimers disease, 2010 Alzheimers symptoms, 2009 Symptoms, 2009). Other common early symptoms include confusion, attention disorders, personality changes, difficulty with languages
