Strong Support
An older woman who had a stroke before suddenly got a terrible headache that came out of nowhere, then started having trouble with dizziness, numbness on one side of her face, and swallowing. A scan five days later finally showed a new stroke in her brainstem, even though two earlier scans had come back normal.

This study tells the exact same story as the claim: an older woman had a sudden, awful headache, then got sick with dizziness and trouble swallowing, but her first two brain scans looked normal — only the third scan showed a stroke in the brainstem. So yes, it supports the claim.
