Vascular dementia, otherwise referred to as multi-infarct dementia, is the second most fundamental cause of dementia in more experienced persons. Since it has a lower profile than Alzheimer's, many people do not speculate that vascular dementia is noticeably dangerous when neglect occurs. It is also difficult to analyze, so it is difficult to know exactly how many people experience the ill effects of vascular dementia. Current assessments account for 15% to 20% of cases of dementia in more established adults with vascular dementia. Vascular dementia occurs when blood supplying vessels to the brain are significantly blocked or limited. Strokes occur when the blood supply that transmits oxygen to the mind is suddenly cut. However, not all people with a stroke develop vascular dementia. Vascular dementia may occur as " noiseless " strokes heap up after some time. Vascular dementia often attracts attention just when the effect of so many strokes means a notable handicap. Staying away from and controlling hazardous factors such as diabetes, hypertension, smoking and high cholesterol can help to control the risk of vascular dementia.
