Vascular dementia

Dementia is caused by different diseases of the brain. These diseases affect the parts of the brain which are used for learning, memory and language.

Vascular dementia is a common type of dementia caused by reduced blood flow to the brain.

Vascular dementia tends to get worse over time. But it is sometimes possible to slow it down.

Symptoms of vascular dementia

Vascular dementia can start suddenly or begin slowly over time.

Symptoms include:

  • slowness of thought
  • difficulty with planning and understanding
  • problems with concentration
  • changes to your mood, personality or behaviour
  • feeling disoriented and confused
  • difficulty walking and keeping balance
  • problems with memory and language – these can also be symptoms of Alzheimer’s disease

These problems can make daily activities increasingly difficult. Someone with the condition may eventually be unable to look after themselves.

Many people with vascular dementia also have Alzheimer’s disease.

Outlook for vascular dementia

Vascular dementia will usually get worse over time. This can happen in sudden steps, with times between where the symptoms do not change much. But it’s difficult to know when this will happen.

Home-based help will usually be needed. Some people will eventually need care in a nursing home.

Although treatment can help, vascular dementia can significantly shorten life expectancy.

But this varies, 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.

Causes of vascular dementia

Vascular dementia is caused by reduced blood flow to the brain. This damages and eventually kills brain cells.

This can happen 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 cut off
  • lots of ‘mini strokes’ (also called transient ischaemic attacks, or TIAs) – these cause tiny but widespread damage to the brain

Often, these problems are linked to underlying conditions. These could be things like high blood pressure and diabetes, or lifestyle factors, such as smoking and being overweight.

Tackling these may reduce your risk of vascular dementia in later life. But it’s not yet clear exactly how much your risk of dementia can be reduced.
