"TIA (Transient Ischemic Attack)"

At the first facility where I worked they had a poster describing this hanging on the wall of the break room I found it very interesting and then one day I witnessed these signs for myself and knew immediately what was happening.  
You don't have to be a nurse like me to understand and know what these signs are.
I love learning and growing and I also love sharing if it will at one point help someone else learn the signs. 
Thanks again to the AHA for sharing this information.  I hope you too find it a useful tool. 




TIA


Excerpted from “Why Rush?”, Stroke Connection January/February 2009 (Science update October 2012)
While transient ischemic attack (TIA) is often labeled “mini-stroke,” it is more accurately characterized as a “warning stroke,” a warning you should take very seriously.
TIA is caused by a clot; the only difference between a stroke and TIA is that with TIA the blockage is transient (temporary). TIA symptoms occur rapidly and last a relatively short time. Most TIAs last less than five minutes; the average is about a minute. Unlike a stroke, when a TIA is over, usually causes no permanent injury to the brain.

The warning signs of a TIA are exactly the same as for a stroke:
numbness
Sudden numbness or weakness of the face, arm or leg, especially on one side of the body
confusion
Sudden confusion, trouble speaking or understanding
trouble-seeing
Sudden trouble seeing in one or both eyes
dizziness
Sudden trouble walking, dizziness, loss of balance or coordination
headache
Sudden, severe headache with no known cause
F.A.S.T. is an easy way to remember the sudden signs and symptoms of a stroke:
  • Face Drooping
  • Arm Weakness
  • Speech Difficulty
  • Time to call 911
Why do some clots dissolve while others don’t? According to Dr. Emil Matarese, director of a primary stroke center at St. Mary’s Medical Center in Langhorne, Pa., the body has naturally occurring clot-busting agents. “Eventually all clots will dissolve, but whether there is damage depends on how long the clot is in place,” Dr. Matarese said. However, because there is no way to predict when a clot will dissolve on its own, time is of the essence. “Whenever you have stroke symptoms, dial 9-1-1 immediately and get to the emergency room so you can be evaluated. Don’t wait to see if the symptoms go away.”
While the vast majority of strokes are not preceded by TIA, about a third of people who experience TIA go on to have a stroke within a year. “TIA is a warning stroke and gives a patient time to act and keep a permanent stroke from occurring,” Dr. Matarese said. “By recognizing TIA symptoms and getting to the hospital, the patient can get help in identifying why the TIA occurred and get treatment — either through medication or surgery — that can prevent a stroke from occurring.”
If a survivor experiences TIA after they have had a stroke, they should go to the emergency room immediately because something in their treatment plan has not worked.
In essence, according to Dr. Matarese, there should be no difference in response to a TIA or a stroke. Although a TIA resolves itself before there is damage, there is no way to predict which clots will dissolve on their own. Stroke — and TIA — are medical emergencies; dial 9-1-1 and tell the operator you think it’s a stroke and note the time the symptoms started. Remember: Time lost is brain lost.
