dementia unit 33 Essay

Dementia can cause the sufferer to experience loss of mental ability, loss of memory, a reduced understanding, and judgement. Dementia can also cause problems with language.

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.

Abnormal changes happen in the brain, and it appears as a sponge-like holes and gaps, causing deterioration in the areas of the brain. This can turn into spongiform degeneration that results in the progressive neurological and neuromuscular symptoms that are associated with CJD. This disorder is a result from a mutation in the gene that regulates the production of the human protein or direct transmission with abnormal protein in infected brain tissue. Scientist believe that there is a transmissible agent that is responsible for causing CJD. This is a slow virus, since it can take many years from exposure to the appearance of

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.

Alzheimer’s: Scientists know that during Alzheimer’s two abnormal proteins build in the brain. They form clumps called either ‘plaques’ or ‘tangles’. These plaques and tangles interfere with how brain cells work and communicate with each other. The plaques are usually first seen in the area of the brain that makes new memories. A lot of research is focused on finding ways to stop these proteins in their tracks and protect brain cells from harm.

A loss of neurons due to amyloid plaques consisting of proteins and neurofibrillary tangles, which is a modified protein, along with free radicals is the cause of this disease. More than often, the patient’s brain with atropy, but this is not always the case. (MedScape) It results in memory loss as well as intellectual disabilities that affect an individual’s daily ADL’s. It is most often found in individual’s over the age of 65, but a small 5% of occurrences happen in one’s 40s or 50s.

Alzheimer’s is when a person has short term memory loss with progressive, irreversible confusion and disorientation. This progressive deterioration of the brain is caused by the destruction of neurons in the central nervous system (CNS) neurons. The destruction of these neurons lead to problems with memory and language, thinking and behavior”. Celular destrucyion is related to the buildup of analoid plaques ans neurofibrillary tanglwa in the brain” (Kinn’s) The body system that is affected when a patient has Alzheimer’s Disease is the Neurological System. Alzheimer’s is a form of dementia. Some forms of dementia

Dementia effects your memory and a person’s ability to achieve a normal everyday task and activities.

1.1 neurodegenitve disease is a common cause of dementia . which means the brain cells known as neurons are dieing quicker then the rest of the brain which leads to more of a decline in the persons mental health such as memory loss language and some of there physical abilitys. it dpend on what part of the brain is affected by the dementia. also other causes of demtia are brain tumors head injurys

Alzheimer’s Disease is the gradual mental depreciation that can happen in middle to old age because of degeneration or damage to the brain.

There are many types of Dementia such as Vascular Dementia, Dementia with Lewy bodies (DLB), Mixed Dementia, Parkinson 's disease, and as mentioned before Alzheimer’s disease. Each form effects the person in a slightly different way and can be hard to diagnose at first.

Alzheimer’s disease: this is most common cause of dementia.Brain cells are surrounded an abnormal protein and internal structure also damaged.In time chemical connection are between brain cells are lost and some cells die. Symptoms may include difficulties with find right words,solving problems,making decision or understand things in three dimension

Once the disease hits the hypothalamus life expectancy is greatly reduced because a person becomes unable to tell when they need sustenance. This is all caused by abnormal deposits of proteins from amyloid plaques and tau tangles throughout the brain, and once-healthy neurons stop functioning, lose connections with other neurons, and die (Site this). Finally the brain has shrunk and damage is widespread throughout the brain.

Dementia is a broad term for a brain disease that is acquired. It develops when nerve cells in the brain deteriorate and do not regrow. The disease affects an individual’s memory, behavior, and their ability to comprehend and clearly think. Although the rate of deterioration varies, dementia causes a decline in an individual’s vocational and social functions. The most common form of dementia is Alzheimer’s disease (ASHA, 2015).

The research shows that these symptoms are common among the older people. The most common disease is Alzheimer but there are some diets that help the person to prevent the condition.
