I often hear people say that a person suffering from Alzheimer’s is not the person they knew. I wander to myself. Who are they then? –Bob DeMarco.
What is Alzheimer's disease?
Alzheimer's disease is a disease that slowly and little by little destroys brain cells. It is neither transmittable nor contagious, but is the single most common cause of dementia. A condition that affects about 10 percent of those aged over 65 and about 20 percent of those aged over 75. In the UK, up to 750 000 people suffer from dementia, costing billions of pounds mostly for institutional care, and causing countless distress and upset to the careers and relatives of patients. What is dementia?
Dementia is the term used to describe a general decline in all areas of mental ability. The symptoms involve worsening in cognitive processes memory, language, thinking and so on. With important repercussions on behavior. About 50 per cent of people with dementia are suffering from Alzheimer's disease, about 20 percent from vascular dementia caused by blockages in the supply of blood to the brain, and about 20 percent from lower body dementia characterized by tiny spherical deposits in the brain. Only about 10 percent of dementia cases are treatable or potentially reversible. Being caused by illnesses such as vitamin B12 deficiency, a brain tumor, syphilis, alcohol dependence or a subdural hematoma. Usually, demanding illnesses were divided into presenile under 65 years of age at onset and senile over 65 years. Although this is now seen as rather an illogical division, it has helped in the search for genes that might underlie early-onset Alzheimer's.
Who discovered it?
Alois Alzheimer (1864–1915), who first describe the disease, was a German psychiatrist and pathologist. In 1906, he approved an autopsy on the brain of a 56-year-old woman, Auguste D Frankfurt. Auguste had died after several years of progressive mental deterioration characterized by confusion and memory loss. In her cerebral cortex, the part of the brain responsible for reasoning and memory, he found strange bundles of nerves, which he termed neurofibrillary tangles, and accumulations of cellular debris. He offered his findings at a meeting in late 1906, and published them in 1907; speculate that the nerve tangles and plaques were responsible for Auguste's dementia. Dementia is a disease in mental ability, its bad enough to affect a human’s everyday life style. There are plenty of symptoms when it comes down to dementia such as lost of memory, lack of communication, language, lack of focus, judgment, and visual perception. Alzheimer’s is a memory loss and other academic abilities. Alzheimer’s disease accounts for fifty to eighty percent of dementia cases. There are plenty of warning signs to signal that you could be dealing with Alzheimer’s like memory loss, hard time planning of solving problems, difficulty completing simple tasks such as putting on clothes or tying your shoes, having trouble understanding visual images, new problems with words or speaking, misplacing things and remembering where you placed them, poor judgment, withdrawal from work, and change in mood and personality.
Who is likely to get Alzheimer's disease?
A number of risk factors for the disease have been identified, so some people are more likely to be affected than others, but it is unlikely that the disease could be traced to a single cause. It is more likely that a combination of factors lead to its development, with the importance of particular factors differing from one person to another. Although age obviously plays a major role less than one person in a thousand under the age of 65 suffers from Alzheimer's. Raising to about one person in 20 over 65 most people over 80 stay mentally alert. So while the chance of suffering from the...
