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.
DWI MRI can detect ischemia much earlier than standard CT scanning or spin echo MRI can and provides useful data in patients with stroke or transient ischemic attack (TIA). (See the image below.)
