Types of dementia vascular dementia

Previously known as multi-infarct or post-stroke dementia, vascular dementia is less common as a sole cause of dementia than Alzheimer's is, accounting for about 10% of dementia cases.

Brain changes

Brain imaging can often detect the blood vessel problems implicated in vascular dementia. In the past, evidence for vascular dementia was used to exclude a diagnosis of Alzheimer's disease (and vice versa).

That practice is no longer considered consistent with pathologic evidence, which shows that the brain changes of several types of dementia can be present simultaneously. When any two or more types of dementia are present at the same time, the individual is considered to have 'mixed dementia'.

Symptoms

Impaired judgement or ability to make decisions, plan or organise is more likely to be the initial symptom, as opposed to the memory loss often associated with the initial symptoms of Alzheimer's. This occurs because of brain injuries such as microscopic bleeding and blood vessel blockage. The locations, number and sizes of brain injuries determine how the individual's thinking and physical functioning are affected.
