Facts about and introduction to Alzheimer's disease
Alzheimer's disease (AD), senile dementia of the Alzheimer type (SDAT) or simply Alzheimer's is the most common form of dementia. This incurable, degenerative and fatal disease named by the German psychiatrist and neuropathologist Alois Alzheimer who in 1906 was the first to describe it. Generally diagnosed disease in people over 65, although the less prevalent early-onset Alzheimer's can occur much earlier. In September 2009 the number of people worldwide with Alzheimer's Diagnosis more than 35 million. The incidence of the disease is supposed to reach about 107 million people in 2050.
Symtoms of Alzheimer's disease
Although the course of Alzheimer's disease is unique for every individual, there are many common symptoms. The earliest observable symptom is often mistakenly thought to be 'age-related anxiety', or signs of stress. In the early stages of the disease, is the most commonly accepted symptom is loss of memory, such as difficulty remembering newly learned facts. When Alzheimer's disease is suspected, the diagnosis is usually made by behavioral and cognitive tests, often followed by some form of tomographic imaging of the brain. As the disease progresses appears common symptoms such as confusion, irritability and aggression, mood swings, stress sensitivity, memory disorders and signs of aphasia and apraxia, and a general withdrawal when the psychic functions gradually deteriorate. Gradually deteriorate the bodily functions, ultimately leading to death. Individual prognosis is difficult to assess, as the duration of disease varies. It may take several years before a person with Alzheimer's may clear symptoms and a diagnosis. The average life expectancy after diagnosis is approximately seven years. Fewer than three percent live more than fourteen years after diagnosis.
Development and cause of Alzheimer's disease
The cause and development of Alzheimer's disease is not well understood. Research shows that the disease associated with plaque and tangels in brain tissue. Currently, they offer treatments that are given a small symptomatic benefit, but there is still no treatment that can delay or halt disease progression. By 2008, more than 500 clinical studies have been done to identify a possible treatment for Alzheimer's, but it is not known if any of the tested action strategies will show promising results. A number of non-invasive, life style habits have been suggested for the prevention of Alzheimer's disease, but sufficient evidence that these recommendations will lead to the dough ring decreases, missing. Mental stimulation, exercise and balanced diet proposed, both as a possible prevention and a sensible way to manage the disease.
Because Alzheimer's is degenerative and can not be cured is patient care important and often takes a loved role as the primary caregiver. Alzheimer's disease is known to be a heavy burden on the caregiver. Social, psychological, physical and economic factors can affect the caregiver's life. In developing countries, Alzheimer's is one of the most costly diseases to society.
