Vascular Dementia

Vascular dementia, also known as multi-infarct dementia, is the second most common dementia type in older people. It's caused when reduced blood flow damages brain tissue. Blood flow to brain tissue may be decreased. Or it may be completely blocked by a blood clot. There are two types

  • Mixed dementia. This type occurs when symptoms of both Alzheimer and vascular dementia continues.
  • Multi-infarct dementia. This may occurs after repeated small, often "restrained" blockages affect blood flow to different parts of the brain. The changes that occur after each blockage may not be apparent, but over time, the combined effect starts to cause symptoms. This is also called vascular cognitive impairment.
