BANGKOK, Thailand -- Alzheimer's and dementia can be triggered by
small silent strokes caused by high blood pressure, but "birthdays are
dangerous" and can be fatal for elderly people, warned a World
Federation of Neurology former president.
"We can begin preventing some dementia by preventing strokes.
That's the big news," said Dr. Vladimir Hachinski, a clinical
neurological sciences professor at Canada's Western University.
"The cutting edge, the big thing about Alzheimer’s disease, is that
with Alzheimer’s disease, pathology is very common -- a lot of people
have [Alzheimer’s] pathology -- but you need a trigger. And the
trigger is stroke," Dr. Hachinski said in an interview.
"It doesn't necessary have to be clinical stroke. There are little
silent strokes.
"So the big news is that you can prevent the Alzheimer’s pathology
from becoming dementia by treating the risk factors and preventing
stroke."
Dr. Hachinski specializes in stroke, vascular dementia and
Alzheimer's, and helped establish Canada's first acute stroke unit.
