A stroke is a medical emergency that happens when blood flow to part of the brain is interrupted or when a blood vessel in the brain bursts. Some people experience warning symptoms days or weeks beforehand, often from a transient ischemic attack (TIA), sometimes called a “mini-stroke.” A TIA is temporary, but it can be a serious warning that a full stroke may follow.
Important: there is no guaranteed “one month before” timeline. Some people have no warning signs at all, while others may have symptoms shortly before a stroke. Still, certain symptoms should never be ignored.
1. Sudden Weakness or Numbness on One Side
Temporary weakness, heaviness, or numbness in the face, arm, or leg—especially on one side—can be a TIA warning sign.
2. Brief Trouble Speaking
Sudden slurred speech, difficulty finding words, or not understanding speech—even if it resolves quickly—needs urgent evaluation.
3. Temporary Vision Changes
Blurred vision, double vision, or sudden loss of vision in one eye can be linked to circulation problems.
4. Sudden Dizziness or Loss of Balance
Unexpected vertigo, unsteadiness, or trouble walking can sometimes signal stroke risk, especially with other symptoms.
5. Severe Headache Unlike Usual
A sudden intense headache, especially if unusual for you, may need urgent medical attention.
6. Facial Drooping That Comes and Goes
Even brief facial asymmetry or drooping can be a serious red flag.
7. Episodes of Confusion
Sudden confusion, trouble thinking clearly, or unexplained disorientation should not be dismissed.
8. Sudden Trouble Swallowing
Difficulty swallowing without another explanation can sometimes occur with neurological events.
9. Repeated Mini Episodes That Resolve
Short bursts of weakness, speech trouble, or numbness that go away may be TIAs.
10. Uncontrolled Risk Factors + New Symptoms
If you have high blood pressure, diabetes, smoking history, atrial fibrillation, or prior stroke and develop any neurological symptoms, act quickly.
Use FAST for Stroke Recognition
F – Face
Ask the person to smile. Is one side drooping?
A – Arms
Ask them to raise both arms. Does one drift downward?
S – Speech
Is speech slurred or strange?
T – Time
Call emergency services immediately.
Don’t Wait for Symptoms to “Pass”
A TIA may last minutes and disappear, but it can be a warning sign of a major stroke soon after. Temporary symptoms still require urgent medical care.
