Please describe what vascular dementia is?

Mini strokes: Vascular dementia refers to a kind of dementia that is caused by problems with the blood vessels in the brain (usually plaque formation, just as in cardiac disease) which results in loss of brain tissue due to lack of adequate oxygen and blood flow. In a sense it is like having very tiny strokes.

Following TIA/CVA: Vascular dementia is a general term describing problems with reasoning, planning, judgment, memory and other thought processes caused by brain damage from impaired blood flow to your brain.
