Dementia with Lewy bodies is closely related to Parkinson's disease and often has some of the same symptoms, including difficulty with movement. Front temporal dementia (including Pick's disease) – In front temporal dementia, the front and side parts of the brain are damaged over time when clumps of abnormal proteins form inside nerve cells, causing them to die. At first, changes in personality and behavior may be the most obvious signs. Depending on where the damage is, the person may have difficulties with fluent speech or may forget the meaning of words or objects. 2) Memory problems are usually the most obvious symptom in people with dementia.
People with lewy bodies often suffer hallucinations. Frontal lobe dementia Frontal lobe dementia including Picks disease , in this form of dementia damage to9 brain cells is more localised than in Alzheimers disease , usually beginning in the front part of the brain . Initially personality and behaviour are more affected than memory but in later stages symptoms are similar to Alzheimers. An early sign that someone's language is being affected by dementia is that they can't find the right words – particularly the names of people. The person may substitute an incorrect word, or may not find any word at all.
Although there a small amount of cases of Alzheimer’s and frontotemporal dementia can be inherited from a previous generation. Vascular dementia is where the blood supply to the brain is interrupted, if there is restricted or stopped blood supply to the brain that’s when the cells being to die which results in brain damage. * Alzheimer’s disease Alzheimer’s is the most common form of dementia, this form of the disease is the loss of cells in brain which causes the brain to shrink. The medical term for this is ‘Atrophy’. The most affected part of the brain is the Cerebral Cortex; this part
The cause of the brain cells dying and the deterioration of the connectors is not fully known. Vascular dementia is a form of dementia caused by damage to the brain through deprivation of oxygenated blood. Causes are preventable and include high blood pressure, heart problems, diabetes and high cholesterol. Rarer forms of dementia are Creutzfeldt-Jakob disease (CJD) and Biswanger’s disease. 1.2 Types of memory impairment Whilst long term memory loss is experienced, short term memory loss can cause more problems, although it is not the same in every case.
1. UNDERSTAND THE NEUROLOGY OF DEMENTIA 1.1 Describe a range of causes of dementia syndrome Dementia syndrome is caused by damage to the brain cells; this damage interferes with the ability of brain cells to communicate each other. The most common causes of dementia are called neurodegenerative diseases, and include Alzheimer’s disease, frontotemporal dementia, and dementia with Lewy bodies. When brain cells can no longer communicate normally, thinking, behaviour and feelings can be affected. Dementia is an umbrella term for number of diseases; "over 130 are known today" that affect the memory, behaviour, and motor skills.
For instance people with dementia can be affected by grief as in the most common of circumstances they are elderly and may have suffered the loss of a partner. Greif can affect people in a variety of ways and emotionally it can suppress a person’s appetite leading to dehydration and mal nutrition, or someone comfort eating and eating excessive amounts leading to weight gain and possibly someone becoming obese. 2. Explain how poor nutrition can contribute to an individual’s experience of dementia. If someone has poor nutrition
Your risk of developing dementia increases as you get older, and the condition usually occurs in people over the age of 65. Dementia is a syndrome (a group of related symptoms) associated with an on-going decline of the brain and its abilities. This includes problems with: • memory loss • thinking speed • mental agility • language • understanding • judgement People with dementia can become apathetic or uninterested in their usual activities, and have problems controlling their emotions. They may also find social situations challenging, lose interest in socialising, and aspects of their personality may change. A person with dementia may lose empathy (understanding and compassion), they may see or hear things that other people do not (hallucinations), or they may make false claims or statements.
Subcortical vascular dementia, this is caused by a series of small changes to blood vessels deep inside the brain. A person usually does not notice these changes but they can overtime damage parts of the brain that are important for attention, memory and language. Dementia with Lewy bodies can cause common dementia symptoms these include,
Unit 533 - Understand the process and experience of dementia Learning outcome 1 - Understand the neurology of dementia 1. Describe a range of causes of dementia syndrome There are many different forms of dementia and each has its own causes. Dementia may also be a symptom that develops in the later stages of some illnesses. Some of the most common forms or causes of dementia include: • Alzheimer’s disease • Vascular dementia • Parkinson’s disease • Dementia with Lewy bodies • Huntington’s disease • Alcohol related dementia – Korsakoff’s syndrome • AIDS related dementia • Fronto Temporal Lobar Degeneration (FTLD) • Creutzfeldt-Jakob disease. Alzheimer’s disease Alzheimer’s disease is the most common form of dementia and accounts for between 50 and 70 per cent of all cases.
Unit 40 Working With Dementia Milestone 1 P1 + P2 the types of dementia includes Alzheimer's disease, this the most common cause for dementia. Dementia is a group of symptoms associated with a decline in the way the brain functions which affects the memory and the way people behave. In alzheimer's disease there is a large loss of brain cells it is unknown to how it is caused the thoughts to the increased risk of developing this is increasing age, a family history of the condition so in the genes, previous severe head injuries and lifestyle factors and conditions associated with vascular disease, which is also another type of dementia. There is also other forms of dementia such as pick's disease, this is a dementia with Lewy bodies which is also a common form of dementia affecting over 100,00 people, although it affects a lot it is still relatively rare and causes slow shrinking of brain cells due to excess protein build up. The term dementia describes the loss of mental ability associated with gradual death of brain cells.
