The disease of Alzheimer’s disease, named after German psychologist Alois Alzheimer, appears to be a disease of the 20th century, but degeneration of the brain, cognitive impairment and behavioural problems worrying and psychiatric that characterize the disease probably have for centuries. A brief history of Alzheimer’s disease lesson tells us that while Dr. Alzheimer is namesake of the disease, Alzheimer’s Emil Kraepelin colleague played an equally important role in the identification of the disease. Isolated Kraepelin and brings together the symptoms of the disease, suggesting were a single disease process, while Alzheimer’s was the first to really understand what was happening in the brains of Alzheimer’s patients. He discovered unusual plaques and tangles in the brain of one of his patients, a woman of 50 year of age, who exhibits symptoms of the disease identified by Kraepelin.After Kraepelin, and the identification of the disease at the turn of the century XXLa Alzheimer’s disease Alzheimer’s disease history shows that many no progress was made in understanding and treating the disease, which could only be had been diagnosed with post mortem with an autopsy, until the end of the 20th century. The disease was diagnosed in patients between the ages of 45 and 65, and labeled as “presenile dementia”. The name of Alzheimer’s disease only gained popularity in the 1970s and 80 as a label for patients older than 65. The disease is now recognizable and diagnosable, symptoms that may appear in patients over the age of 30. Normally, an aggressive type of Alzheimer’s disease that occurs in patients under the age of 65 has a known genetic factor, while the emergence of the disease in patients over 65 years of age has a number of other factors in regard to their developmentsuch as health, occupation and the environment.Recent advances in science and technology have led to a promising new era in the history of Alzheimer’s disease. Cognex, the first drug approved by the FDA, used to slow down the process of the disease, hit the markets in 1990 and three other followed. Drugs slow deterioration cognitive in patients with mild to moderate Alzheimer’s to boost poor levels of acetylcholine in the brain, which are crucial for the healthy functioning of neurons. Other investigations are made on ways to prevent the development of Alzheimer’s disease. Certain hormones such as estrogen and anti-inflammatory drugs as aspirin have found an effect of mediation and environmental factors, such as mentally challenging occupations, dance, and chess have been found to decrease the chances of older people develop Alzheimer’s disease. Even something as simple as using a belt of security or town could be crucial for the prevention of the disease of Alzheimer. early detection techniques are being perfected to improve the treatment of the disease. For example, genetic research has discovered genetic markers of relatives of Alzheimer’s disease, as well as Alzheimer’s disease not family. In addition, advanced technology, such as MRI and PET images, analysis, are being used to detect structural changes in the brain that may indicate the development of Alzheimer’s disease before symptoms begin. As the Baby Boomer generation begins to age, scientists fear the pressure that a large number of dementia patients could be accommodated to the systems of health and social welfare; Therefore, researchers are struggling to eradicate Alzheimer’s disease.
