(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.
