1 in 10 healthy adults has had 'silent stroke'

Authors say that silent stroke was probably not severe enough to cause recognizable symptoms such as vision problems, facial weakness or trouble walking, but it was still a blockage of a brain artery and it reduced your thinking powers just a bit.

The study looked at the MRI scans of more than 2,000 people over age 62.

To reduce the risk of silent strokes, experts say, people should control high blood pressure, diabetes, cholesterol and watch their diets.
