symptoms occur when the brain is damaged by certain diseases, including Alzheimer's disease and damage caused by a series of small strokes.
Dementia is progressive, which means the symptoms will gradually get worse. 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.
Symptoms of dementia may include the following:
- Loss of memory − this particularly affects short-term memory, for example forgetting what happened earlier in the day, not being able to recall
- Mood changes − people with dementia may be withdrawn, sad, frightened or angry about what is happening to them.
- Communication problems − including problems finding the right words for things, for example describing the function of an item instead of naming it.
conversations, being repetitive or forgetting the way home from the shops.
Long-term memory is usually still quite good.
In the later stages of dementia, the person affected will have problems carrying out everyday tasks and will become increasingly dependent on other people.

What causes dementia?
There are several diseases and conditions that result in dementia. These include:
- Alzheimer's disease − The most common cause of dementia. During the course of the disease the chemistry and structure of the brain change,
- Vascular dementia − If the oxygen supply to the brain fails due to vascular disease, brain cells are likely to die and this can cause the symptoms of
- Dementia with Lewy bodies − This form of dementia gets its name from tiny abnormal structures that develop inside nerve cells. Their presence in the
- Fronto-temporal dementia (including Pick's disease) − In fronto-temporal dementia, damage is usually focused in the front part of the brain. At first,

usually the first noticeable sign.

stroke, or over time through a series of small strokes.

disorientation and hallucinations, as well as problems with planning,
reasoning and problem solving. Memory may be affected to a lesser degree.
This form of dementia shares some characteristics with Parkinson's

Rarer causes of dementia
HIV/AIDS, and Creutzfeldt−Jakob disease (CJD). Some people with multiple sclerosis, motor neurone disease, Parkinson's disease and Huntington's disease
may also develop dementia as a result of disease progression.
Mild cognitive impairment
disease or another type of dementia, particularly if a person is still managing well. When this occurs, some doctors will use the term 'mild cognitive impairment' (MCI).
Recent research has shown that individuals with MCI have an increased risk of developing dementia. The conversion rate from MCI to Alzheimer's is 10-20 per cent
each year, so a diagnosis of MCI does not always mean that the person will go on to develop dementia.
Who gets dementia?
- There are about 750,000 people in the UK with dementia.
- Dementia mainly affects people over the age of 65 and the likelihood increases with age. However, it can affect younger people: there are over
- Dementia can affect men and women.
- Scientists are investigating the genetic background to dementia. It does appear that in a few rare cases the diseases that cause dementia can be

than others of developing dementia.
Can dementia be cured?
can temporarily alleviate some of the symptoms of some types of dementia. These drugs include the three acetylcholinesterase inhibitors:
- Aricept (donepezil hydrochloride)
- Exelon (rivastigmine)
- Reminyl (galantamine).
moderate stages of Alzheimer's disease should be given treatment with one of the acetylcholinesterase inhibitors.

drugs are effective for symptoms of vascular dementia. Treatment should be aimed at the underlying cardiovascular (heart and circulatory) problems.
How can I tell if I have dementia?
forgetful does not necessarily mean that you have dementia: memory loss can be an effect of ageing, and it can also be a sign of stress or depression. In rare cases,
dementia-like symptoms can be caused by vitamin deficiencies and/or a brain tumour. If you are worried about yourself, or someone close to you, it is worth
discussing your concerns with your GP.
Having a diagnosis may also mean it is possible to be prescribed drugs for Alzheimer's disease. Whether you are someone with dementia or a carer, a
diagnosis can help with preparing and planning for the future.
Dementia can be diagnosed by a doctor - either a GP or a specialist. The specialist may be a geriatrician (a doctor specialising in the care of older people), a
neurologist (someone who concentrates on diseases of the nervous system) or a psychiatrist (a mental health specialist). The doctor may carry out a number of tests
to check basic thinking processes and the ability to perform daily tasks. They may request further tests, such as a brain scan or a more in-depth assessment of
memory, concentration and thinking skills.
Can dementia be prevented?
indicate that a healthy diet and lifestyle may help protect against dementia. In particular, exercising regularly, avoiding fatty foods, not smoking, drinking alcohol in
moderation and keeping mentally and socially active into old age may help to reduce the risk of developing vascular dementia and Alzheimer's disease.
