Can silent strokes cause dementia?

But some strokes don't cause any noticeable symptoms. These silent strokes still increase dementia risk.

How do you test for silent stroke?

If you have a brain CT scan or anMRI, the image will show white spots or lesions where your brain cells have stopped functioning. That's how doctors will know you've had a silent stroke. Other signs are so subtle that they're often mistaken for signs of aging, like: balance problems.

Are there warning signs days before a stroke?
