The idea that “your body warns you a month before a stroke” is a common headline, but there is no reliable countdown of specific symptoms that happens exactly one month before a stroke. A stroke can occur suddenly. However, some symptoms can be warning signs of an increased stroke risk or a transient ischemic attack (TIA, sometimes called a “mini-stroke”) and should not be ignored.
Possible stroke warning signs (remember FAST)
- F — Face drooping: One side of the face feels numb or looks uneven.
- A — Arm weakness: Sudden weakness or numbness in one arm (or one side of the body).
- S — Speech difficulty: Slurred speech, trouble understanding, or confusion.
- T — Time to call emergency services: These symptoms require urgent evaluation.
Other warning signs that need prompt medical attention
- Sudden vision changes (loss of vision or double vision)
- Sudden severe headache unlike usual headaches
- Sudden dizziness, loss of balance, or trouble walking
- Sudden numbness or tingling on one side of the body
- New confusion or difficulty understanding
- A brief episode of stroke-like symptoms that goes away (possible TIA)
A TIA can be a warning that a more serious stroke may follow, sometimes soon afterward, so it should be treated as an emergency even if symptoms disappear.
If you or someone nearby is having sudden stroke symptoms right now, seek emergency help immediately.
