Quick F.A.S.T. Checklist (From the American Stroke Association):
- Face Drooping: Does one side droop when smiling?
- Arm Weakness: Raise both arms—does one drift down?
- Speech Difficulty: Is speech slurred or strange?
- Time to call 911: Note the time symptoms started and get emergency help immediately, even if symptoms fade.
Why These Signs Matter: The Science Behind the Warning
Organizations like the CDC and Mayo Clinic stress that acting on these signs early improves outcomes dramatically. For instance, TIAs are medical emergencies because they signal underlying problems like narrowed arteries, blood clots, or high blood pressure. Research shows that prompt evaluation after a TIA can help prevent up to 80% of subsequent strokes through lifestyle changes, medications, or procedures.
Women, in particular, sometimes report more nonspecific signs like sudden fatigue or confusion, which can delay recognition. No matter your age or gender, these changes deserve attention.
