The claim that “your body warns you exactly one month before a stroke” is misleading. A stroke can happen suddenly, and there isn’t a reliable set of 10 symptoms that predict a stroke specifically one month in advance.
However, there are warning symptoms that should never be ignored, particularly symptoms of a transient ischemic attack (TIA)—sometimes called a “mini-stroke.” A TIA can cause stroke-like symptoms that disappear within minutes or hours, but it is still a medical emergency because it can precede a major stroke.
10 warning signs to take seriously
-
Sudden weakness or numbness, especially on one side of the face or body.
-
Sudden facial drooping or an uneven smile.
-
Sudden difficulty speaking or slurred/garbled speech.
-
Sudden difficulty understanding what other people are saying.
-
Sudden vision changes, including loss or blurring of vision in one or both eyes.
-
Sudden dizziness or loss of balance/coordination.
-
Sudden difficulty walking or unexplained stumbling.
-
Sudden severe headache with no known cause, particularly if it is unusual for you.
-
Sudden confusion or difficulty thinking clearly.
-
Sudden difficulty swallowing.
The most important part
Don’t wait to see whether these symptoms go away. Use BE-FAST:
-
B — Balance: sudden loss of balance
-
E — Eyes: sudden vision changes
-
F — Face: one side droops
-
A — Arms: one arm becomes weak or numb
-
S — Speech: speech becomes strange or difficult
-
T — Time: call emergency medical services immediately
Even if the symptoms completely disappear, they could represent a TIA and require urgent medical assessment. If symptoms are happening now, call your local emergency service immediately rather than waiting for them to improve.
