The risk of getting dementia increases with age, but it is important to remember that the majority of older people do not get dementia. It is not a normal part of ageing. Dementia can happen to anybody, but it is more common after the age of 65 years.
When people between the age of 40 and 60 do develop dementia, it is called younger-onset dementia.
There are many different types of dementia. The most common include:•Alzheimer’s disease is the most common form of dementia, accounting for between 50 and 70 per cent of all cases.
•Vascular dementia is the broad term for dementia associated with problems of circulation of blood to the brain.
•Lewy body disease is a form of dementia caused by abnormal structures in the brain called Lewy bodies,
There are lots of factors which could cause dementia. Those who have someone in the family with Dementia are at a higher risk of developing Dementia because Dementia can be in the genes and those genes are passed to the next generation. Someone with Downs Syndrome is also at high risk of developing Dementia in earlier years of life. Others factors which could cause dementia are: Stroke, Diabetes, High cholesterol, smoking and alcohol-Korsakoff’s Syndrome.
Even though I knew my grandmother for 17 years before she died my mother told me that I had never met her. According to her my grandmother had not been "herself" for years because the affects of her advanced age had basically destroyed the person she once was and turner her into a living zombie. Although humans live an average of 85 years, things such as memory loss and lack of motor control can completely change a person and in a way kill her years before she dies. Vascular Dementia has the same general symptoms as "old age" only it typically occurs in younger people. Binswanger's Disease is a specific type of vascular dementia, probably the most common form, which affects people at approximately age 60. Most people diagnosed with this disease do not live past five years of its onset(1). Currently, not much is known about Binswanger's Disease; in many ways it resembles various other neurological disorders making it difficult to diagnose. The trademark of this disease is damage to the blood vessels in the deep white matter of the brain(1),(4),(5). The pons, basal ganglia, and thalamus are typical sites for these lesions(5),(7). A Magnetic Resonance Imaging scan is one of the most reliable ways to see this damage(5),(6). However, with outward symptoms such as depression, strokes, and disease of heart valves(1),(2),(3),(5) an MRI is not typically one of the first diagnostic tool used and the disease proceeds unchecked.
clumps of abnormal proteins insides the brain cells. These proteins are called the Tau proteins they take a form of picks bodies. This slowly leads to frontotemporal dementia.
Alzheimer’s Disease is the most common cause of dementia. Alzheimer’s is a type of dementia that causes problems with memory, thinking and behavior. Symptoms usually develop slowly and get worse over time. It can become severe enough to interfere with daily tasks. Allie Hamilton is suffering from dementia.
Alzheimer’s is a result from a combination of factors that cause progressive brain deterioration that affects the memory and behavior of an individual. There are two known risk factors. The first risk factor is age. Alzheimer’s usually affects people older than 60, and rarely affects those younger than 40. The average age
Contrary to common belief, Dementia is not a disease, it is a term that encompasses a collection of symptoms. These symptoms are associated with numerous diseases that involve the impairment of cognitive functions (DoH, 2013).

Alzheimer’s disease, named after Dr. Alois Alzheimer, is a disease that is on the rise in America and the rest of the world. People should learn as much as they want about this disease, because as you age, your chances of becoming an Alzheimer’s Disease, or AD, patient increases. It is estimated that approximately 3 percent of Americans between the ages of 65 and 74 have the illness, and more than half of all people over age 85 have the ailment.
Alzheimer disease generally occurs in people over seventy five years of age; however it does strike people in their forties, fifties, and sixties, but this is rare. When Alzheimer’s disease occurs prior to the age of sixty five, it is referred to as early onset Alzheimer’s.
Dementia is a long-term condition that normally affects people aged 65 and over, younger people can be affected. Having dementia can cause loss of key functions to the brain, such as; loss of memory; confusion; speech and language problems; loss of ability to make judgements; loss of concentration; difficulty in processing information; changes in behaviour and personality. These all lead to a person not been able to function properly. The person’s ability to function deteriorates over a period of time and is usually at least 6 months before positive diagnosis of dementia can be made. Dementia is caused when the brain is damaged by diseases such as Alzheimer’s which is the most common of dementia, vascular which is a series of mini strokes,
Delirium, Depression, and Dementia are some of the most common psychological diagnoses in the elderly today. The three D’s are difficult to differentiate between in older adults because they overlap with each other and can all exist in the same patient at once. Delirium, Dementia, and Depression all affect the elderly’s quality of life and often increase the risks for one another (Downing, Caprio & Lyness, 2013). For the purpose of this paper I will be focusing primarily on the diagnosis of Dementia, the prevention, and nursing measures associated with it, but first I would like to differentiate between Delirium and Depression because Dementia is often associated with the two in the older adult population.
Alzheimer's disease is the most common cause of dementia. People may develop symptoms after age 60. Some people may have early-onset forms of the disease do to a defective gene. Alzheimer's disease usually progresses slowly over about eight to 10 years. The cognitive abilities slowly decline. The affected areas of the brain includes memory, language, judgment, and spatial abilities. Another type of dementia is Lewy body dementia. It affects approximately 10 percent of people with dementia, making it one of the most common types of dementia. Lewy body dementia becomes more common with age. Lewy body dementia symptoms are similar to symptoms of Alzheimer's disease. Its unique features include fluctuations between confusion and clear thinking (lucidity), visual hallucinations, and tremor and rigidity (Parkinsonism) (Dementia.
The clinical picture in dementia is very similar to delirium, except for the course. Delirium is an acute transitory disorder. By contrast Dementia is a long term progressive disorder (with the exception of the reversible dementias). The course of AD can range anywhere from 1.5 to 15 years with an average of about 8.1 years (Terry , 1988). AD is usually divided into three stages mild, moderate, and severe. Throughout these stages a specific sequence of cognitive deterioration is observed (Lezak, 1993). The mild stage begins with memory, attention, speed dependent activities, and abstract reasoning dysfunction. Also mild language impairments begin to surface. In the moderate stage, language deficits such as aphasia and apraxia become prominent. Dysfluency, paraphasias, and bizzare word combinations are common midstage speech defects. In the severe stage the patient is gradually reduced to a vegetative state. Speech becomes nonfluent, repetitive, and largely non-communicative. Auditory comprehension is exceedingly limited, with many patients displaying partial or complete mutism. Late in the course of the disease many neuropsychological functions can no longer be measured. Also primitive reflexes such as grasp and suck emerge. Death usually results from a disease such as pneumonia which overwhelms the limited vegetative functions of the patient.
This usually occurs in older adults aged above 65; however, it is a disability and not a normal symptom of aging. Chances of inheritability are present, but it depends on the individual and the type of dementia (Alzheimer Australia, 2011). The Global Deterioration Scale provides a detailed explanation of the seven stages of cognitive decline in dementia (Alzheimer’s Association of Canada, 2005). Types of Dementia There are four main types of dementia, with AD being the most widespread form. It accounts for almost two thirds (50 -70 percent) of the cases and thus more extensively studied (Miller, 2009)....
Dementia is a major neurocognitive disorder that interferes with the independence of the elderly by inhibiting memory and thinking skills. Fifty to eighty percent of dementia cases constitute of Alzheimer’s diagnoses; consequently Alzheimer’s disease is the most common type of dementia and currently affects 5.2 million Americans. Most of these cases are patients above the age of 65 and by 2050; 13.8 million Americans in total will suffer Alzheimer’s due to aging of the general population, specifically the baby boomers. Total cost to society ranges from $157- $215 billion (Associated Press). Some would assume the cost of Alzheimer’s to be incurred by pharmaceuticals or medical costs, however RAND Corp suggests dementia cost to society is from care rather than treatment. Therefore, assistance provided by informal providers and directs caregivers incur a majority of the financial and social cost. Currently, the workforce does not have the capacity or training to care for these unique patients; the delivery system needs to address Alzheimer’s as the population ages and more and more fam...
