What are the main differences between Vascular Dementia and Alzheimer's Disease?

A member of my family has been diagnosed with Vascular Dementia so the more detail someone can give me, the better. Many thanks.

Vascular dementia is caused by narrowing arteries cutting off oxygen supply to the brain cells - proper medication can really help/even improve mental function IF brain cells haven't been impaired by a stroke. No one yet knows what causes Alzheimer's, but there are connections to the brain not being able to rid itself of waste materials the same way "normal" brains do and that's what many of the meds work on. An Alzheimer's diagnosis is more discouraging because the medications are still all pretty new/experimental and only slow down the progress of the disease, at best. Chances are, with Vascular Dementia, if your family member is able to exercise a little, gets really good nutrition and treatments that clear out arteries, there's a chance for a better quality of life than with Alzheimer's. Good for you for caring enough to search out answers!

Dementia is the start of alzheimers Its not quite in to the first stages of alzhimers but as the diseases progresses you will see the first stages of alzheimers. Do a little resarch on the inter net it helps a lot I found out alot about it!
Good Luck

A big difference is that Alzheimer's can't learn new things and they forget the near present, but Vascular patients don't always have these symptoms. They are just confused about reality.
