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.
These two conditions constitute the vast majority of cases, and although their symptoms can sometimes be managed, they are irreversible. Dementia associated with Altzheimers disease progressively worsens. In addition, symptoms of dementia vary depending on the cause, but it includes some common signs and symptoms such as loss of memory, difficulty in communicating, inability to learn or remember new information, difficulty with planning and organization. The signs of dementia can also include symptoms like difficulty with coordination and motor functions, changes in personality, inability to reason, inappropriate behavior, paranoia, agitation and hallucinations.

Unit 13 1.1 The term Dementia is described by a number of symptoms such as memory lose, changes in mood, and unable to communicate normally. A mental decline in the ability to function in every day life. 1.2 Key functions of the brain affected by dementia are frontal lobe, temporal lobe, parietal lobe, occipital lobe, cerebrum and hippocampus. 1.3 Dementia can be mistaken for depression, delirium and age-related memory impairment because they are very similar in appearance. 2.1 The medical model sees the patient with dementia as a problem.
Vascular dementia which occurs after a stroke, is the second most common dementia, but there are many other conditions that can cause symptoms of dementia, including some that are reversible, such as thyroid problems and vitamin deficiencies. Dementia is often incorrectly referred to as

As well as these cognitive symptoms, a person with dementia will often have changes in their mood. For example, they may become frustrated or irritable, withdrawn, anxious, easily upset or unusually sad. Dementia is progressive which means the symptoms gradually get worse over time. How quickly dementia progresses varies greatly from person to person. As dementia progresses, the person may develop behavior problems which may seem out of character.
How fast dementia progresses will depend on the individual person and what type of dementia they have. Each person is unique and will experience dementia in their own way. It is often the case that the person's family and friends are more concerned about the symptoms than the person may be themselves.

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.
2 How dementia affects decision-making Dementia is the umbrella term for a number of conditions which cause damage to the brain cells. The most common form is Alzheimer’s disease which has a gradual progression. The next most common type is vascular dementia which has a step-like progression. About one in four people with Parkinson’s disease also develop dementia. Short-term memory loss, disorientation and loss of concentration are common symptoms.
The term dementia is used to describe a group of symptoms, a person with dementia is a person with a range of disabilities which can be more difficult to recognise than physical disabilities dementia is more of a generic term and includes a vast range of conditioms and there causes this is because dementia is more tham just memory loss it is also effects the cognitive function so things like remembering, comprehension, awareness, judgement etc this is due to damage or disease in the body more than what is expected from normal ageing. The key functions of the brain that are affected by dementia include the cerebrum, dementia with Lewy bodies (DLB) affects the cerebrum. In DLB small, round lumps of proteins build up in the grey matter. These spheres harm nerve cells,
