Vascular Dementia


Vascular dementia is the broad term for dementia associated with problems of circulation of blood to the brain and is the second most common cause of dementia.


In this form of dementia brain cells are deprived of oxygen and die. This can occur in distinct parts of the brain, leaving other areas relatively unaffected.


There are a number of different types of vascular dementia. Two of the most common are multi-infarct dementia and Binswanger's disease.


Multi-infarct dementia is caused by a number of small strokes, called mini-strokes or Transient Ischaemic Attacks (TIA) and is probably the most common form of vascular dementia.


Binswanger's disease (also known as subcortical vascular dementia) is associated with stroke-related changes to the brain. It is caused by high blood pressure, thickening of the arteries and inadequate blood flow.


Vascular dementia may appear similar to Alzheimer's disease, and a mixture of Alzheimer's disease and vascular dementia can occur in some people.
