Transient Ischemic Attacks
Transient ischemic attacks (TIAs), or “mini-strokes,” happen when blood flow to the brain is temporarily blocked. Sufferers may experience blurry or lost vision on both eyes; tingling or numbness of the mouth, or are unable to speak clearly.
Effects of Transient Ischemic Attacks
The effects of TIAs may last only a few minutes, but this does not mean they should be ignored. TIAs may be predictors of strokes. It’s estimated that about 15 percent of those who have a stroke first experienced a TIA.
Warning signs of a stroke include:
- Sudden numbness or weakness of face, arm or leg, especially on one side of the body.
- Sudden confusion or trouble speaking or understanding speech.
- Sudden trouble walking, dizziness, or loss of balance or coordination.
- Sudden severe headache with no known cause.
- Blurred or double vision, drowsiness, and nausea or vomiting.
Remember, not every stroke sufferer will have all of these signs, and sometimes the symptoms will go away only to return again. Call 911 right away if you or someone you know has one or more of these symptoms. The sooner medical treatment is given, the better the chances for survival and healing.
