This paper is on dementia, a late-life disorder, as it pertains to the geriatric population. “It is

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.

Alzheimer 's disease (AD) is a progressive degenerative disease of the brain from which there is no recovery. There are three brain abnormalities that are the hallmarks of the Alzheimer’s disease is initially caused by plaques buildup in the brain’s neurons as illustrated in figure 1. The support structure that allows the flow of the nutrients through the neurons gets damaged and ultimately there is loss of connection among the neurons and they die off (National Institute of Health, 2015). This causes the brain tissue to shrinks, which is called atrophies. All this ultimately lead the victim of this disease to face difficulties in governing emotions, recognize errors and patterns, coordinate movement, and remember. Ultimately, a person with AD loses all memory and mental functioning.

In advanced stages, loss of speech entirely can occur, though emotional signals can still be cognitive and recognizable. At this point, pertinent exhaustion and apathy are presented as the patient loses the ability to perform the most simplest of tasks. Because the patient becomes bedridden at this point, they are completely dependent on the caregivers. Death usually occurs at this point, not directly due to the disease, but from outside sources such as pneumonia.

The term ‘dementia’ is used to describe a syndrome associated with an ongoing decline of the brain and its abilities. This includes problems with memory loss, thinking speed, mental agility, language, understanding, and judgment. People with dementia can become apathetic or uninterested in their usual activities, and have problems controlling their emotion. They also fine social situation challenging, lose interest in socialising and aspect of their personality may change. The majority of people who are diagnosed with dementia have either Alzheimer’s disease or vascular dementia, or a combination of the two. (Source 1) As the disease progresses, the person experiencing dementia becomes more vulnerable and their needs often complex; which requires appropriate care and management (Kitwood, 1997).this leads me to the next distinctive feature of patients with dementia.

Dementia is a term used to describe the symptoms of a number of illnesses which effect the function of the brain. It is an umbrella term describing the progressive decline in a person’s cognitive ability. The type and severity of symptoms varies with each type of dementia and is usually has a gradual onset, is progressive and irreversible. (1)

Dementia can be defined as a decline in mental ability severe enough to interfere with daily life (alz.org). More than often, individuals affected by dementia are over the age of 65. In the United States, there are more than three million cases of dementia each year. According to World Health Organization, the number of people living with dementia is currently estimated at 47.5 million worldwide and is expected to increase to 75.6 million by 2030 (World Health Organization 2015). Dementia is caused by physical modifications in the brain and is known for loss of memory and mental abilities. It’s a progressive disease which means it gets worse over time. If diagnosed early on, the quality of life for people with dementia as well as their family members can be significantly improved. There are many different types of dementias although some are far more reciprocal than others. One of the most common types of dementia is Alzheimer’s disease. Other few types of dementias are “Vascular dementia, Mixed dementia, Parkinson 's disease and Frontotemporal dementia (Krishnan, D. S)”. All of the various forms of dementia tend to have similar symptoms which consequently makes it hard to determine the type of dementia a patient may be suffering from.

Dementia refers to a syndrome which results in deterioration in thinking, memory, behavior, and ability to execute everyday activities and duties. Despite the fact that the syndrome is mainly associated with the older people, it is not a normal aspect or part of ageing. One of the major causes of dementia is the aspect of Alzheimer's disease. This disease contributes to about 60 to 70 percent of the cases of dementia. Dementia possesses psychological, physical, economic, and social impacts in relation to the family, caregivers, and the entire society. Dementia affects each individual in a diverse or different way with reference to the impact of the disease and personality following the development of the syndrome (Gao et al, 2013 p. 447).

An estimated 47.5 million people suffer from dementia. Every 4 seconds one new case of dementia is diagnosed. Dementia is a term that describes certain symptoms such as impairment to memory, communication and thinking. It is a group of symptoms and not just one illness. Even though one‘s chance of getting dementia increase with age, it is not a part of aging. Dementia is usually diagnosed after a series of assessments that includes a physical evaluation, memory tests, imaging studies and blood work. It affects three aspects of one’s mental function, cognitive dysfunction (Problems with memory, language, thinking and problem solving), psychiatric behavior (changes in personality, emotional control, social behavior and delusions) and difficulties with daily living activities (driving, shopping, eating and dressing). “The median survival time in women is 4.6 years and in men 4.1 years” (Warren, 2016).

One of the most prominent and perhaps most feared condition associated with aging is dementia. The family of disorders can cause individuals to lose their mind, reducing one from being a complex, thinking, feeling human being to being confused and vegetative, unable to recognize their loved ones. Serious dementia affects nearly 37 million people globally, but predictions of how those numbers will change over the next few decades are conflicting (textbook). Although we know dementia as to do with damage to nerve cells in the brain, there are ongoing studies looking at correlations between other health issues and these types of diseases.

Alzheimer’s disease is the progressive loss of memory and mental functions. The disease affects memory, thought control, language, and other cognitive functions. The disease typically appears with old age and is often found age 60. Alzheimer’s causes the brain to develop clumps and tangles fibers in the brain tissue along with the loss of neuron connections. Throughout the brain, proteins are abnormally distributed and they form tangled bundles of fibers and amyloid plaques. Some neurons fail to function properly and lose their connections, which are necessary for the transmission of messages to the body. The hippocampus is the key brain structure in the formation of memories and often experiences the first signs of damage.

Dementia is a condition resulting from obtained brain disease and distinguished by progressive decay in memory and other cognitive fields such as judgment, abstract thinking, language, and executive functioning. This disease is usually caused by degeneration in the cerebral cortex, the part of the brain responsible for thoughts, memories, actions, and personality. Death of brain cells in this area leads to the impairments that distinguish dementia. Though the cognitive outline of single diagnosed with dementia vary somewhat by etiology, the degree of deterioration stands for a decrease from previous levels of cognitive functioning and is enough to impede with social and occupational functioning. This downfall is beyond what might be expected from normal aging in a person. It can cause impairment with everyday activities such as dressing, feeding, and bathing.

There are four main types’ dementia, Alzheimer’s disease, vascular dementia, frontotemporal dementia and other dementia disorders. Dementias are considered to be neurodegenerative because of the death or nerve cells in the brain. These disorders are caused by toxic proteins stored in the brain. The abnormal proteins will cause the brain function to weaken, which will eventually lead to dead cells. The proteins also damage the spaces in between the nerves causing them to transmit improperly. Alzheimer’s disease is the most common type of dementia, named after Alois Alzheimer, a German neurologist. In one case, there was a woman who began having hallucinations, disorientations, and memory loss. It increased over the years until her death at the age of 55. Vascular dementia, the second most common dementia. A disease when the blood vessels become affected in the brain. It is similar to the Alzheimer’s disease because it has been called to be the ‘forgotten’ dementia. In contrast to the Alzheimer’s disease, vascular dementia results from multiple causes, like “haemodynamic (blood flow to the brain) disorders (for example, strokes), thromboembolism (small blood clots originating mainly from the carotid artery or heart that block small blood vessels in the brain), small blood vessel disease in the brain (which results in a gradual reduction in blood supply to the brain), and heamorrhage (bleeding) into or around

Dementia is a disease which causes mental debility and affects one’s way of intelligent, attentiveness, recollection and problem-solving (NHS, 2013). As a result of dysfunction of brain cells in some parts of the brain it affects the thinking process then dementia occurs and it usually comes with age (Ibid). It is estimated that 560

Dementia is a vague term used to describe a person that has loss of memory and change in behavior and activities. It goes beyond the forgetfulness and absent minded. It is commonly used In reference to the elderly, when cognitive abilities start to slip from one’s own control. Dementia cannot be diagnosed due to memory loss alone. It must be accompanied by two or more interruptions of brain function. Individuals who suffer from a disease that causes dementia undergo a number of changes. Simple daily tasks such as dressing or bathing may also become a problem. Anything can be a cause for dementia, a stroke, a car accident or even another disease. Here, I will compare four most frequent causes of dementia with four least

###To begin with, the begging stage to Alzheimer's disease is called mid alzheimer's disease (early-stage). (Stages) This stage tends to last for two to four years. (Alzheimer's) At this stage the person can still function independently, and be part of social events and activities, but some things start to become difficult. He or she may start having memory lapses. They may start forgetting familiar words and may start to forget where they set objects
