Senile Dementia

Throughout this line of study, Alzheimer’s disease is a specific form of dementia. According to Alzheimer’s Association, dementia is a general term for a decline in mental ability that is severe enough to hinder daily life. Memory loss is a symptom of dementia and the most common type of dementia is Alzheimer’s. One of the most common and severe symptom of Alzheimer’s is difficulty remembering newly learned information. The changes of Alzheimer’s normally begin in the part of the brain that affects learning (Overview Alzheimer's Association). Some other symptoms of Alzheimer’s include gradual memory loss, the decline in capability to carry out everyday tasks and the loss of their language skills. According to Bialystok the rate of

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

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.

The person may become confused when handling money and undergo personality changes, appearing to no longer care about those around them. Swings are common and the person may become tearful for no apparent reason, or become convinced that someone is trying to harm them.In advanced cases people may also adopt unsettling behaviour like getting up in the middle of the night or wander off and become lost. Some people lose their inhibitions and sense of what is acceptable behaviour, undress in public or make inappropriate sexual advances. The person may become incontinent, have difficulty eating and drinking and may become completely dependent on others.2. Symptoms usually develop suddenly and progress in a step like way where a sudden worsening is followed by a period of stabilisation. Common symptoms include poor concentration and difficulties with communication. memory loss may also lead to confusion.As vascular dementia does not affect all of the brain, the individual may be able to retain more of their abilities and memory loss may not appear until later in the progression of the disease. This means that the individual may be more aware of their deteriorating health and may therefore be more at risk of depression.3. Dementia with Lewy Bodies is a

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 is caused when the brain is damaged by diseases, such as Alzheimer’s disease, vascular dementia, Lewy body disease, a series of strokes or even a group of symptoms which may result from brain injury, vitamin/hormonal imbalance, drugs and alcohol. These diseases have factors in common and can cause a person to have their mental

4. Vascular Dementia – This form of dementia results from many strokes. When a patient has a stroke, the blood flow is interrupted to the brain and the result is brain tissue damage (Types of Dementia, 2011). These patients normally lose their cognitive ability before their memory.

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).

The term dementia is used to describe an illness that affects the memory. Patients can suffer from forgetfulness, loss of memory and the inability to remember new information. As well as being unable to speak and be understood by others and be unable to carry out general tasks. Patients can also suffer from mood changes and all reasoning. This all has an effect on daily routines and people become unable to look after themselves properly and manage their own personal care.

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).

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.

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

Vascular Dementia can occur after a person has a stroke due to major blood vessels being blocked.

Dementia is a "clinical syndrome, or condition that presents several different symptoms of which memory problems and impaired intellectual functioning are the hallmark" (Lillrank). Dementia is actually a term used to describe a wide range of symptoms. Two of the most common types of dementia are: Vascular dementia and Alzheimer's. Some symptoms of dementia include loss of short-term memory. Other initial manifestations can include confusion,

There are many disease processes that culminate in the onset of dementia; the most common of which is Alzheimer’s disease. The syndrome is frequently associated with a progressive decline in brain function and the associated physical and mental abilities, including memory, language and cognitive function.
