DEM-301 Understand the Process and Experience of Dementia 1.1 Describe a range of causes of dementia syndrome. Fixed cognitive impairments are due to a single incident.traumatic brain injurys may cause generalised damage to the white matter of the brain or localised damages. A brief reduction in the supply of blood and oxygen to the brain may lead to this type of dementia. A stroke or brain infection can also be the cause of dementia. Excessive alcoholic intake results in alcoholic dementia.
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

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.
If it is genuine dementia it won't get better. There is medication to ease the symptoms but no cure. 2.1: A medical model for dementia would be when a persons memory is affected by a medical disease or a condition as a result of brain trauma which affects the area of the brain that is responsible for memory. Dementia is an umbrella term that covers a wide variety of ailments that affects a person ability to remember. It can range from a bump to the head to a medical disease that attacks the brains ability to function correctly, such as vascular dementia that alters blood flow to the brain.
Dementia with Lewy Bodies can be closely related to Parkinsons Disease and there is a theory that Dementia with Lewy Bodies interferes with two neurotransmitters called dopamine and acetylcholine which assist in the brains functions. In Frontotemporal dementia – Picks Disease, the brain shrinks in the frontal and temporal lobes and a build of specific protein’s occur in these areas. Once the proteins come together, they become toxic and cause brain cells to die. It is not understood why these proteins build up. There are other dementia types too, namely Creutzfeldt-Jakob Disease (CJD) caused by an abnormal infectious protein call Prion which cause nerve damage to
Dementia is basically damage in the brain where there is a build-up of abnormal proteins which causes a decline in mental ability. The decline can be either rapid or a gradual process. Typical causes of Dementia can be one specific disease such as Alzheimer’s which accounts for 60-80% of cases, or Parkinson’s or motor neurone disease, however Dementia is not a specific disease but rather describes a wide range of symptoms. In most cases, dementia is not inherited directly from family members, although a small number of cases can be inherited from family members. Other less common causes of dementia may include depression, head injuries, alcohol misuse, brain tumours, infections of the brain such as HIV, Strokes, or lack of Vitamin B in the diet.
Lesley Chubick PS124 Introduction to Psychology Alzheimer’s, Disorder of the Brain Unit 7 Assignment The mental disorder I chose for this assignment is on Alzheimers. Alzheimers is a form of dementia that is a disease that attacks the brain’s intellectual functions such as memory, orientation and calculation. This degenerative brain disease attacks one in ten men and women over 60. The question many of us have is what is Alzheimers, what is its effect on the brain and is there a cure? Being a degenerative disease Alzheimers attacks the brain through exponentially greater cell death and tissue loss which results in decreased brain size and brain activity.
1.1 Dementia is a term used to describe a broad range of between 100-150 diseases which affect the brain. Some of the conditions are better than others, while some show more symptoms then others. You can get symptoms of the disease to slow its progress; however dementia is not currently reversible. There are many types of dementia such as; Alzheimer’s- which is the most common type of dementia. Lewy body dementia Picks disease Multi-infarct Dementia Huntington’s Creutzfeldt Jacob Disease 1.2 The brain consists of three main sections: the hindbrain, the midbrain and the forebrain.
Other symptoms include aggression, compulsive behaviour, being easily distracted and language problems. Outline the risk factors for the most common causes of dementia. Alzheimers Risk Factors Most people affected by this type of dementia are aged 65 or older and the likelihood of developing this disease doubles about every 5 years. So after 85 years old the risk is nearly 50% Also if you have family who have this disease, the risk to yourself increase. Genes also play a role in the risk to you developing this disease.
