Vascular dementia is considered to be the second most common prevalent type of dementia after Alzheimer’s disease. This is caused due to the low blood flow that damages the brain or neural tissues. Reduction of blood flow can be due to partial blockage by a clot. Symptoms can be seen either gradually or in the form of a stroke or maybe after major surgery. While it is mainly caused due to obstruction in blood flow to the brain, no cure is known for vascular dementia.
