There isn’t strong proof that strokes always give clear, reliable warning signs exactly 90 days in advance. However, research and clinical reports suggest that some people experience early or “prodromal” symptoms weeks to months before a stroke, especially mini-strokes (TIAs).
Here are 9 warning signs that may appear weeks or months before a stroke and should never be ignored:
-
Sudden numbness or weakness
Especially on one side of the body (face, arm, or leg), even if it goes away. -
Brief trouble speaking or understanding speech
Slurred speech, confusion, or difficulty finding words that resolves after minutes or hours can be a TIA. -
Sudden vision problems
Blurred, double vision, or temporary loss of vision in one or both eyes. -
Severe or unusual headaches
Especially if they are sudden, intense, or different from past headaches. -
Dizziness or loss of balance
Trouble walking, poor coordination, or unexplained falls. -
Sudden fatigue or weakness
Extreme tiredness without a clear cause, sometimes reported before strokes. -
Confusion or memory problems
Sudden difficulty thinking clearly, focusing, or remembering things. -
Chest discomfort or shortness of breath
These can be related to heart problems that increase stroke risk. -
Mini-strokes (TIAs)
Temporary stroke-like symptoms that fully resolve — these are one of the strongest warning signs and greatly increase stroke risk in the following days or months.
🚨 Important to know
-
TIAs are medical emergencies, even if symptoms disappear.
-
A major stroke often occurs within days to months after a TIA if untreated.
-
Not everyone gets warning signs — some strokes happen suddenly.
🧠 What to do
If any of these symptoms appear, even briefly:
-
Tell a trusted adult immediately
-
Seek medical care right away
-
In emergencies, call emergency services
