Small, symptomless strokes more than double the risk of developing Alzheimer
disease, according to a large study by Dutch researchers (N Engl J Med. 2003;348:1215-1222).
In a population-based study of 1015 people aged 60 to 90 years and free
of dementia and stroke, participants underwent magnetic resonance imaging
and cognitive testing in 1995-1996 and were retested in 1999-2000. The researchers,
from Erasmus Medical Center, Rotterdam, the Netherlands, found that participants
who had silent strokes revealed during the first testing period were more
than twice as likely as those without such lesions to develop dementia.
