The claim that “your body warns you one month before a stroke” is a popular health headline, but it is misleading. A stroke can happen suddenly, and there is no reliable one-month warning period. However, some people may experience warning signs (especially from a transient ischemic attack, or TIA—sometimes called a “mini-stroke”) in the days, weeks, or even months before a major stroke.
Here are 10 signs that should not be ignored:
- Sudden weakness or numbness
- Especially on one side of the face, arm, or leg.
- Face drooping
- One side of the face may feel weak or look uneven when smiling.
- Speech problems
- Slurred speech, trouble finding words, or difficulty understanding others.
- Sudden vision changes
- Blurred vision, loss of vision in one eye, or double vision.
- Severe, unusual headache
- A sudden “worst headache of your life,” especially with other symptoms.
- Dizziness or loss of balance
- Trouble walking, coordination problems, or unexplained falls.
- Confusion or trouble thinking clearly
- Sudden difficulty understanding what is happening.
- Temporary symptoms that disappear
- Symptoms lasting minutes and then resolving can still be a TIA and require urgent medical attention.
- New difficulty swallowing
- Trouble controlling swallowing can occur with certain strokes.
- Unusual fatigue or weakness
- Persistent or unexplained weakness may be a warning sign, especially with other risk factors.
A simple way to remember the emergency signs is FAST:
- F — Face: Is one side drooping?
- A — Arms: Can both arms be raised?
- S — Speech: Is speech strange or unclear?
- T — Time: Call emergency services immediately.
If stroke symptoms appear, do not wait to see if they improve. Early treatment can greatly affect outcomes.
