|533 |1.1 |There are many causes of dementia. Dementia is caused by changes to the brain; there are different |
| | |types of Dementia. Vascular dementia is caused when the brains blood supply is disrupted, the brain|
| | |does not get enough oxygen and brain cells die off. Lewys Body dementia is caused by lumps of |
| | |protein in the brain which interfere with chemicals of the brain ‘dopamine’ and ‘acetylcholine’ |
| | |These two chemicals play a role in the function of the brain such as memory, mood etc. Therefore |
| | |when they are interfered with, interfere with the person’s memory, mood and attention span. |
| | |Frontotemporal dementia is caused when the brain is damaged and shrinking of two areas of the brain|
| | |occurs which are the frontal lobe, and temporal lobe. Other causes of dementia can be due to long |
| | |term illnesses such as HIV, CJD and Huntington’s disease which can affect the brain. Brain tumours |
| | |and long term alcohol misuse are amongst other causes of dementia. |
| | | |
| | |People with dementia suffer with different types of memory loss. Long term memory loss, short term |
| | |memory loss etc. It is different for each person but a lot of similar patterns emerge with the |
| | |types of dementia.
