A transient ischemic attack (also called a TIA or mini-stroke) occurs when there is a temporary lack of blood to the brain. Symptoms can appear quickly and may even go unnoticed. They are similar to signs of a regular stroke and can include a sudden onset of:
- Difficulty speaking or understanding speech
- Trouble seeing in one or both eyes (such as double vision, blurred vision, or blindness)
- Trouble walking or dizziness.
This is a serious medical condition, and 911 should be called immediately if you think you or someone else may be experiencing a mini-stroke. Of the approximately 50,000 Americans who have a TIA each year, about one-third will have an acute stroke sometime in the future.
