Outcome 1

1.1 Describe a range of causes of dementia syndrome
Dementia is a term for the progressive disease of brain and describes a serious deterioration in mental function, as memory, language, orientation and judgement , The causes of dementia are still not fully understood. Research in dementia is an ongoing and to date number of types of dementia and their causes have been identified. The brain contains billions of cells, in dementia some of these cells stop working properly. Depending what part of brain this occurs in it will affect the way an individual thinks, remembers, walks and communicates. There is a range of causes of dementia here are son of them:-

Mixed dementia Mixed dementia is a condition in which abnormalities characteristic of more than one type of dementia occur simultaneously in the brain. Physicians may also call this condition “Dementia multifactorial.” In the most common form of mixed dementia, the abnormal protein deposits associated with Alzheimer's disease coexist with blood vessel problems linked to vascular dementia. Alzheimer’s brain changes also often coexist with Lewy bodies, the abnormal protein deposits characteristic of dementia with Lewy bodies and Parkinson’s disease dementia. In some cases, a person may have brain changes linked to Alzheimer’s disease, vascular dementia and dementia with Lewy bodies.
Alzheimer’s disease is the most common cause of dementia. It is caused by nerves cells dying in certain parts of the brain and the connection between affected nerve cells deteriorates. As dementia progresses it spreads and affects other parts of the brain. The cause of brain cells dying and deterioration of the connectors is not fully known yet.
Vascular dementia is caused by deprivation of oxygenated blood to the brain. Oxygenated blood is carried around
