Symptoms of vascular dementia
Vascular dementia can start suddenly or come on slowly over time.
- slowness of thought
- difficulty with planning and understanding
- problems with concentration
- mood, personality or behavioural changes
- feeling disoriented and confused
- difficulty walking and keeping balance
- symptoms of Alzheimer's disease, such as problems with memory and language (many people with vascular dementia also have Alzheimer's)
These problems can make daily activities increasingly difficult and someone with the condition may eventually be unable to look after themselves.
Getting medical advice
See a GP if you think you have early symptoms of dementia, especially if you're over 65 years of age.
If it's spotted at an early stage, treatment may be able to stop the vascular dementia getting worse, or at least slow it down.
If you're worried about someone else, encourage them to make an appointment with a GP and perhaps suggest that you go with them.
Your GP can do some simple checks to try to find the cause of your symptoms. They can refer you to a memory clinic or another specialist for further tests if needed.
Tests for vascular dementia
There's no single test for vascular dementia.
The following are needed to make a diagnosis:
- an assessment of symptoms – for example, whether there are typical symptoms of vascular dementia
- a full medical history, including asking about a history of conditions related to vascular dementia, such as strokes or high blood pressure
- an assessment of mental abilities – this will usually involve a number of tasks and questions
- a brain scan, such as an MRI scan or CT scan, to look for any changes that have taken place in the brain
Treatments for vascular dementia
There's currently no cure for vascular dementia and there's no way to reverse any loss of brain cells that occurred before the condition was diagnosed.
But treatment can sometimes help slow down vascular dementia.
Treatment aims to tackle the underlying cause, which may reduce the speed at which brain cells are lost.
This will often involve:
- eating healthily
- losing weight if you're overweight
- stopping smoking
- getting fit
- cutting down on alcohol
- taking medicines, such as those used to treat high blood pressure, lower cholesterol or prevent blood clots
Outlook for vascular dementia
Vascular dementia will usually get worse over time. This can happen in sudden steps, with periods in between where the symptoms do not change much, but it's difficult to predict when this will happen.
Although treatment can help, vascular dementia can significantly shorten life expectancy.
But this is highly variable and many people live for a number of years with the condition or die from some other cause.
If you or a loved one has been diagnosed with dementia, remember that you're not alone. The NHS and social services, as well as voluntary organisations, can provide advice and support for you and your family.
Causes of vascular dementia
Vascular dementia is caused by reduced blood flow to the brain, which damages and eventually kills the brain cells.
This can develop as a result of:
- narrowing and blockage of the small blood vessels inside the brain
- a single stroke, where the blood supply to part of the brain is suddenly cut off
- lots of "mini strokes" that cause tiny but widespread damage to the brain
In many cases, these problems are linked to underlying conditions, such as high blood pressure and diabetes, and lifestyle factors like smoking and being overweight.
Tackling these might reduce your risk of vascular dementia in later life, although it's not yet clear exactly how much your risk of dementia can be reduced.
