(NewsNation) — Often called a mini stroke, transient ischemic attacks (TIAs) occur when blood flow to the brain is briefly blocked, causing a few minutes of stroke symptoms.
Although a TIA doesn’t cause long-term damage, about one in three people will have a stroke. Of those, about half will have one within a year after the mini stroke, according to the Mayo Clinic.
What are symptoms of a TIA stroke?
Symptoms appear suddenly and resemble those of a stroke. But TIAs often last a few minutes, and symptoms should disappear within an hour.
- Numbness or weakness in the face, arm or leg, especially on one side of the body
- Confusion, trouble speaking or difficulty understanding speech
- Trouble seeing in one or both eyes
- Difficulty walking, dizziness, loss of balance or lack of coordination.
