A stroke can sometimes be preceded by warning signs, but the idea that “your body always warns you exactly one month before a stroke” is not medically accurate. Some people have temporary warning episodes called transient ischemic attacks (TIAs)—often called “mini-strokes”—that can happen hours, days, or sometimes weeks before a major stroke. Other people have no warning symptoms at all.
Possible warning signs that should not be ignored include:
- Sudden weakness or numbness
- Especially on one side of the face, arm, or leg.
- Face drooping
- One side of the face may feel weak or look uneven.
- Speech problems
- Slurred speech, trouble finding words, or difficulty understanding others.
- Sudden vision changes
- Loss of vision, blurred vision, or double vision in one or both eyes.
- Sudden severe headache
- Especially a “worst headache ever” or a headache with other neurological symptoms.
- Dizziness or loss of balance
- Trouble walking, coordination problems, or unexplained falls.
- Confusion or unusual difficulty thinking
- Sudden problems with memory, awareness, or understanding.
- Weakness or clumsiness in a hand or arm
- Dropping objects or inability to lift an arm normally.
- Numbness or tingling
- Particularly if it appears suddenly and affects one side of the body.
- A sudden change in usual abilities
- Any rapid, unexplained change in movement, speech, vision, or behavior.
A useful emergency reminder is FAST:
- F — Face: Is one side of the face drooping?
- A — Arm: Can the person raise both arms?
- S — Speech: Is speech strange or unclear?
- T — Time: Call emergency services immediately.
If these symptoms appear—even if they disappear after a few minutes—medical evaluation is important because a TIA can be a warning of a possible stroke.
