Dementia Memory Impairmentia

Dementia is a cognitive disorder which causes a loss of brain functions which mainly affect memory .

Dementia is a term used to describe a collection of signs and symptoms that happen to the brain when it is affected by the progression of certain diseases such as vascular dementia (when brain cells die due to lack of oxygen) and Alzheimer’s disease (a specific brain disease). Some of the affects these diseases have are on a person’s memory, language and communication abilities, behaviour and ability to make rational judgements.

The term ‘dementia’ describes a set of symptoms which can include loss of memory, mood changes and problems with communication and reasoning. These symptoms occur when the brain is damaged by certain conditions and diseases, including Alzheimer’s disease, vascular dementia and Creutzfeldt-Jakob disease. 
Age is the greatest risk factor for dementia. Dementia affects one in 14 people over the age of 65 and one in six over the age of 80. However, dementia is not restricted to older people: in the UK, there are over 17,000 people under the age of 65 with dementia, although this figure is likely to be an underestimate.

Dementia is a type of disorder that affects the central nervous system. It’s not a disease itself but a group of symptoms that characterize disease and conditions. It’s commonly defined as a decline in intellectual functioning that is severe enough to interfere with the ability to perform routine activities. It causes significant loss of intellectual abilities, such as memory capacity, severe enough to interfere with social or occupational functioning. Dementia‘s a general term that also includes specific disorders like vascular dementia as well as others.

Alzheimer 's disease is a progressive deterioration of cognitive function sufficient to cause functional disability (Hannaman, Mitchell, Cross, 2011). It is the most common cause of dementia after age 60 with initial signs reflective of hippocampal dysfunction, with poor immediate recall and short-term memory. "As the disease progresses, visuospatial dysfunction (including with directions and geographic disorientation), due to parietal lobe involvement, and executive dysfunction (including difficulty initiating and completing tasks, reduced spontaneity, and apathy). due to frontal dysfunction typically appear" (Hannaman, Mitchell, Cross, 2011, p. 11-6). Median survival rate is 3 years because of

This disease is not considering to be the part of normal ageing, while it becomes more prevalent when age increases and therefore, it affects older people (“Dementia (AIHW)”, 2016).

Dementia is a disorder of the mental processes caused by brain disease or injury. It is marked by memory disorders, personality changes and impaired reasoning.

The term dementia means a serious loss in memory and other intellectual abilities in a formally unimpaired person, further than what might be expected from normal ageing (Dhanani & Wilkins, 2008). The origin of the word dementia is from a latin word

Dementia is not exactly a disease, but rather a large group of symptoms. These symptoms all relate to the decline of memory and thinking skills due to damage of the brain. Memory loss is often confused with dementia, but other symptoms must be present for a dementia diagnosis. Dementia patients suffer from a combination of cognitive, behavioral and psychological symptoms.

Dementia is not a disease but rather a group of symptoms caused by disorders that affect the brain (National Institute of Neurological Disorders and Stroke, n. d). The hallmark of dementia, memory impairment, is accompanied by deficits in language, motor function, recognition, or executive function (Stahl, 2013). The most common forms of dementia are caused by Alzheimer’s disease (AD), vascular dementia, Lewy body dementia, and frontotemporal lobar degeneration (Prince et al., 2013). The risk of dementia increases with age. Dementia is rare below the age of sixty but affects about 17% of those between 80 and 85 years of age, 33% of those between 85 and 90 years old, and 50% of those over 90 years of age (Tom et al., 2015). As the

Dementia is a syndrome caused by multiple progressive illnesses that affects memory, thinking, orientation, behaviour, comprehension, calculation, judgement, learning capacity, language, and loss of motivation and emotional control. The syndrome is characterized by Alzheimer’s disease, dementia with lewy bodies, vascular dementia, and frontotemporal dementia. Dementia mainly affects older people. Alzheimer disease is the most common form of dementia.

Dementia is “The loss of intellectual function, such as thinking and memory, which interferes with daily function. It is not a disease in itself, but a group of symptoms that may accompany a condition, all of which produce a gradual decline in intellectual function and almost always a significant deterioration of memory.”(Health Reference Center)

One of the most common forms of dementia, Alzheimer’s disease is a brain disorder which impacts activities of daily living through cognitive changes and memory loss. This is a progressive, neurodegenerative disease which is characterized by language deterioration, poor judgment, confusion, restlessness, mood swings, memory loss, and the inability to mentally manipulate visual information. The onset of Alzheimer’s disease generally begins around the mid-60s, but early signs may occur as early as in the early 40s. Some initial symptoms appear as memory decline, but as the illness progresses it starts to destroy cognition, personality, and the individual’s ability to function, along with restlessness and confusion. The severity, type, sequence,

The dementia statistics Within the United States are not promising, there are at least 5 million people currently living with age-related dementias. As the population increases, these numbers are expected to rise. To put this into perspective, it’s

The National Institutes of Health reports that, “According to their calculations, 13.9% of Americans age 71 and older have some type of dementia.” (National Institutes of Health 1). Dementia is a generic term used in reference to a wide group of symptoms. The disease has no cure and is different in every patient. There are many different definitions and forms of dementia; consequently, while not on purpose, there have been many misdiagnoses and negligence of dementia. Although studies show that dementia is prevalent in 30 to 47% of people over the ages of 85, it is not an inevitable part of aging.
