Symptoms Of Dementia Essay

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

There are several causes of dementia some of them are; a stroke, brain disease, MS, certain medications, shrinkage of the brain, too many opiates over a long period of time and severe alcoholism

As people age, it is natural for them to experience a mild degree of memory loss. However, some cases can be much more severe, and can have a variety of causes. When loss of memory and other mental functions becomes more severe, the condition is known as dementia. Dementia is caused by a variety of disorders, but

There are many different types of dementia and causes of dementia. The first cause is Alzheimer’s disease, which is caused by nerve cells dying in certain areas of the brain. This therefore also affects the connection between the affected nerve cell causing them to deteriorate. Alzheimer’s disease is the most common cause of dementia.

Even diet or illness can affect their abilities or needs. One day a person with dementia will remember, and be quite able, to complete certain tasks but then may be incapable another. This is not their choice it is because the brain is a very complex organ and the chemical changes vary from person to person. The information is still in the memory but the neurotransmitters are able to send messages one day but maybe not the next. If an individual has a water infection they may be more confused and their needs go up whilst their abilities go down. Medication may produce more hallucinations or tremors therefore once again their needs are increased.

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 affects the brain by stopping communication between the nerve cells causing them to die which will have an impact in the way the brain works.

There are many different forms of dementia and each has its own cause. Some of the main type of dementia is Alzheimer’s disease, which is the most common form of dementia affecting 50%-70% of dementia patients (Alzheimer's australia, 2005). This is a degenerative illness which attacks the brain, this is achieved buy tangles which are in the middle of shrunken brain cells and plaques which eventually cause the brain cells to die meaning information can no longer be recalled or assimilated. There are also other types of dementia which include vascular dementia which is caused by circulation of the blood to the brain, Parkinson’s disease which is a disorder of the

Alzheimer 's disease causes 50% to 60% of all cases of dementia (National Institute of Neurological Disorders and Stroke). In addition, researchers have found that two other nervous system conditions, Lewy body disease and Pick 's disease, which were originally incorrectly diagnosed as Alzheimer 's, are emerging as major causes of dementia (National Institute of Neurological Disorders and Stroke). Dementia is considered a late-life disease because it tends to develop mostly in elderly people; as many as half of all people over the age of eighty are suspected of suffering from Alzheimer 's disease (National Institute of Neurological Disorders and Stroke).

Dementia is not considered a specific disease because it is such a broad disease there are many different types.

Dementia is characterized as a condition where the mental processes of cognition and memory start to deteriorate. It is described as a syndrome that hinders the daily lives of those who have it and is characterized by memory and thinking impairment. The most common form of dementia is Alzheimer’s Disease and the second most common is vascular dementia. Dementia is a syndrome occurring usually, but not limited, to people over the age of 40 and is due to brain damage caused by natural deteriorating, stroke or can be brought on by factors such as excessive drinking or drug abuse. Dementia is best cared for in its early stages and, therefore, an early diagnosis is essential. Recognizing the symptoms by both the dementia patient and the

Although some kinds of memory loss are very normal in the aging process, the changes that are caused by aging are not that extreme enough to conflict with it. A number of certain diseases and conditions can cause dementia. These conditions and diseases consist of Parkinson’s disease, strokes, brain tumors, blood clots and Multiple Sclerosis, but the most common disease to cause this is Alzheimer’s disease (Crystal, 2009).

Also, many who have dementia also suffer with high blood pressure, thyroid problems, and vitamin b12 deficiency in folate and thiamine (Mercola)

VD is the second most common type of dementia; consisting of 10 to 30 percent and it is due to dead nerve cells in infected vessels. This is often caused by transient ischemic attacks (Miller, 2009). The two widely known forms of vascular dementia is Multi-infarct dementia (MD) and Binswanger’s disease (BD) also known as sub cortical vascular dementia. MD is a result of Transient Ischaemic Attacks (TIA) that harms the cortex of the brain which is involved with memory. BD is related to stroke and high blood pressure and affects the “white matter” in the brain causing movement difficulties and emotional imbalances (Alzheimer’s Association, 2011). Late adulthood, diabetes mellitus, recurrent strokes and low education are common risk factors of VD however there are preventive measures like smoking, diabetes and sedentary lifestyle (Miller, 2009).
