The claim “Your body warns you one month before a stroke: 10 signs you shouldn’t ignore” is a common online headline, but it is misleading.
A stroke usually happens suddenly, and there is no reliable set of symptoms that appears exactly one month before a stroke. However, some people may experience warning events—especially a transient ischemic attack (TIA), sometimes called a “mini-stroke”—which can occur before a major stroke. TIAs are temporary episodes caused by reduced blood flow to the brain and should be treated as a medical warning.
Possible stroke warning signs include:
- Sudden weakness or numbness of the face, arm, or leg (especially on one side)
- Sudden trouble speaking or understanding speech
- Sudden vision problems in one or both eyes
- Sudden dizziness, loss of balance, or trouble walking
- Sudden severe headache with no known cause
- Sudden confusion
- Facial drooping or an uneven smile
A quick way to remember key signs is FAST:
- F — Face: Ask the person to smile. Is one side drooping?
- A — Arms: Ask them to raise both arms. Does one drift down?
- S — Speech: Is speech slurred or unusual?
- T — Time: Call emergency services immediately if these signs appear.
Risk factors that increase stroke risk include high blood pressure, diabetes, smoking, high cholesterol, atrial fibrillation, and previous stroke or TIA.
If someone has sudden stroke symptoms, seek emergency medical help immediately—waiting to see if symptoms improve can be dangerous.
