A transient ischemic attack (TIA), often called a “mini-stroke,” happens when blood flow to part of the brain is temporarily disrupted. Its symptoms can disappear within minutes or hours, but a TIA is a serious warning sign and needs urgent medical attention.
1. Sudden Facial Drooping
One side of the face may suddenly become weak or droop. The person may have difficulty smiling normally.
2. Sudden Weakness or Numbness
Weakness or numbness, particularly in one arm or one side of the body, can be an important warning sign.
3. Trouble Speaking
Sudden slurred speech, difficulty finding words, or trouble understanding what others are saying should never be ignored.
4. Sudden Vision Problems
Temporary blurred or double vision, or sudden loss of vision in one or both eyes, can occur during a TIA.
5. Sudden Dizziness or Loss of Balance
Unexpected dizziness, difficulty walking, or loss of coordination can sometimes signal a TIA or stroke.
What Should You Do?
Remember FAST: Face, Arms, Speech, Time. If any of these symptoms appear suddenly, seek emergency medical help immediately—even if the symptoms disappear. It is not possible to reliably tell at home whether symptoms are a TIA or a full stroke.
The Bottom Line
A mini-stroke may be brief, but it should never be ignored. Prompt medical assessment can help identify the cause and reduce the risk of a future stroke.
