Answer from Ted Lowenkopf, M.D. , medical director of Providence Stroke Center: Yes, you can have a stroke and not know it. A stroke's effects can be undetectable if the stroke is small or if the tissue damaged does not serve a critical function. Evidence of the stroke would show on a CT scan or an MRI of the brain, but it might not produce symptoms. But you really may be asking if a stroke can occur without your realizing, at the time, that it's happening â such as when you are asleep or when the effects are minor. Letâs look at those two scenarios separately.
Less commonly, one or more tests may be done in specific situations to identify conditions that contribute to risk of stroke. Non-laboratory tests may include a CT scan or MRI of the brain to look for any injury as well as tests of electrical activity and blood flow in the brain.
