Transient ischemic attacks, or TIAs, should no longer be thought of as mere “mini-strokes,” but rather harbingers of a bigger stroke to come, according to the American Heart Association.
In new guidance, the group says that at least 240,000 Americans experience a TIA each year and calls on medical providers to treat TIAs as emergencies.
The statement gives medical providers guidelines on how to evaluate patients who suspect they’ve had a TIA. The condition occurs when a temporary blockage of blood to the brain produces strokelike symptoms that swiftly resolve.
Because symptoms tend to disappear within an hour, it can be hard to diagnose suspected TIAs, according to the guidance.
