Vascular dementia is a type of dementia. It is caused by disease of the small blood vessels in the brain. Parts of the brain called white matter along with grey matter are injured by multiple small strokes.
Vascular dementia occurs when cells below the surface of the brain's cortex die because they do not receive enough oxygen and nutrients. This process is due to hardening and narrowing of the blood vessels within the white matter of the brain. This affects the blood supply.
Factors that may increase your chance of vascular dementia include:
In some people, symptoms appear suddenly with neurological changes like those caused by a stroke. Sometimes, the small strokes that lead to vascular dementia can happen without other symptoms. This makes the condition difficult to detect.
In some cases, symptoms may stabilize or even improve. However in most people, the disease continues to progress.
The main symptoms of vascular dementia include:
Other symptoms that may be present include:
The symptoms of vascular dementia can resemble other causes of dementia, such as Alzheimer's.
Your doctor will ask about your symptoms and medical history. A physical exam will be done.
Pictures may be taken of your brain and bodily structures. This can be done with:
Your heart and brain activity may be evaluated. This can be done with:
Your bodily fluids may be tested. This can be done with blood tests.
There is no known cure for vascular dementia. Reducing risk factors and symptoms are important in trying to slow disease progression and improve quality of life.
Medications can be given to help limit or control symptoms and possibly slow progression of the disease. These include:
There are no definitive guidelines to prevent vascular dementia. However, the following may help reduce your risk:
