10 Early Warning Signs of a Stroke Everyone Should Know
A stroke happens when blood flow to part of the brain is interrupted or when a blood vessel in the brain breaks. Fast treatment can save brain function and improve outcomes, so recognizing warning signs quickly is important.
A helpful way to remember common stroke symptoms is BE FAST:
1. Balance problems
- Sudden dizziness, loss of coordination, trouble walking, or unexplained falls.
2. Eye or vision changes
- Sudden blurred vision, double vision, or loss of vision in one or both eyes.
3. Face drooping
- One side of the face may feel weak or numb.
- Ask the person to smile—one side may not move normally.
4. Arm weakness
- Sudden weakness or numbness in one arm (or leg), especially on one side of the body.
- Ask the person to raise both arms—one may drift downward.
5. Speech difficulty
- Slurred speech, trouble finding words, or difficulty understanding others.
6. Sudden severe headache
- A sudden, intense headache that is unusual for the person may be a warning sign, especially if it occurs with other symptoms.
7. Numbness or tingling
- Sudden loss of feeling or weakness in the face, arm, or leg, particularly on one side.
8. Confusion
- Sudden trouble understanding what is happening or difficulty thinking clearly.
9. Trouble swallowing
- Difficulty swallowing can occur if certain areas of the brain are affected.
10. Sudden loss of coordination
- Problems with movement, balance, or performing normal tasks.
What to do if you suspect a stroke:
- Call emergency services immediately.
- Note the time symptoms started (or the last time the person was known to be well).
- Do not wait to see if symptoms improve.
- Do not give food, drink, or medication unless advised by medical professionals.
Remember:
Stroke symptoms can appear suddenly, but they can also come and go (such as in a transient ischemic attack, or “mini-stroke”). Even if symptoms disappear, urgent medical evaluation is still needed because it may be a warning sign of a future stroke.
