Vascular dementia

Vascular dementia is caused by reduced blood flow to the brain. The lack of blood flow can cause damage to, or even kill brain cells.

Reduced blood flow has several potential causes, including:

• Narrowing of blood vessels.
• After a stroke, which is a blockage or a burst of a blood vessel. This is known as a post-stroke dementia.
• Mini strokes, also known as transient ischemic attacks (TIA), cause tiny widespread damages.

Symptoms are similar to other dementia. These can occur suddenly after a stroke, or slowly after some time.
