Ask the doctor: What to do about TIAs?

What to do about TIAs?

Q. For the last few years, I have been experiencing what I think are mini-strokes. The first time it happened, I lost the sight in one eye for about a minute. Sometimes the vision in both eyes gets blurred for a few minutes. A few weeks ago I could not think of the word "battery" while talking with a friend.
