The type of dementia caused by small strokes, vascular dementia, is also sometimes referred to as âsmall vessel diseaseâ or multi-infarct dementia because it is caused by small strokes (infarcts) caused by blood clots in the small blood vessels of the brain.
Dementia causes. Dementias can be caused by brain cell death, and neurodegenerative disease - progressive brain cell death that happens over time - is associated with most dementias. However it is not known if the dementia causes the brain cell death, or the brain cell death causes the dementia. But, as well as progressive brain cell death, like that seen in Alzheimer's disease, dementia can be caused by a head injury, a stroke, or a brain tumor, among other causes.
