Thanks for the input tod, when I'm more awake I would like to read more on this. Vascular dementia is aggressive, and when its done its work it leaves only the shell of the person, coma and death, and this comes quickly, unlike Alzheimer's death can be years or decades away after its affliction, even worse imo. I watched a rather healthy person who had a brilliant mind succumb to vascular dementia brought on by many-mini brain strokes that can happen without detection creating holes in the brain somewhat like swiss cheese. This stuff is scary. I hope a care someday is found for these awful things. A person can be otherwise be healthy, but if the brain is either effected or stops working with memory loss other vitals and organs may or will shut down.
