Vascular dementia is a common type of dementia caused by reduced blood flow to the brain. It's estimated to affect around 150,000 people in the UK.
Dementia is the name for problems with mental abilities caused by gradual changes and damage in the brain. It's rare in people under 65.
Vascular dementia tends to get worse over time, although it's sometimes possible to slow it down.

Vascular dementia can start suddenly or begin slowly over time.
These problems can make daily activities increasingly difficult and someone with the condition may eventually be unable to look after themselves.
See a GP if you think you have early symptoms of dementia, especially if you're over 65 years of age.
If it's found at an early stage, treatment may be able to stop 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.

There's currently no cure for vascular dementia and there's no way to reverse any loss of brain cells that happened 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:
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 several 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.
Vascular dementia is caused by reduced blood flow to the brain, which damages and eventually kills brain cells.
This can happen as a result of:
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.
