Can you suffer a stroke and not know?

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.
