Strokes are often described as sudden, catastrophic events—one moment you’re fine, the next your world changes. But here’s what many people don’t know: the body often sends warnings weeks before a stroke happens.
These warnings are called transient ischemic attacks (TIAs) or “mini-strokes.” They’re caused by temporary blockages in blood flow to the brain, and they resolve within minutes or hours. But they are not “just a passing spell.” They are your brain’s desperate attempt to tell you something is terribly wrong.

Ignoring a TIA is like ignoring a fire alarm because the flames aren’t visible yet. Up to 15% of people who have a major stroke experience a TIA first—often within days or weeks beforehand.

Here are 10 signs your body may send in the month before a stroke. If you or someone you love experiences any of these, do not wait. Do not dismiss. Seek medical help immediately.
