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.
Stroke-Related Disorders. MRI can be used to diagnose stroke, which occurs when blood flow to the brain stops. Two major types of strokes are ischemic, caused by a lack of oxygen reaching brain tissue due to artery narrowing or blockage, and hemorrhagic, caused by a broken vein or artery.RI brain scans can diagnose several types of disorders.

However, their ability to diagnose conditions such as mental illness is still limited.
