For anyone who has had a stroke, “time lost is brain lost,” according to Dr. Jeffrey L. Saver, a professor of neurology at the University of California, Los Angeles, and a member of the American Stroke Association/American Heart Association.
In fact, during every minute immediately following a stroke, two million neurons (brain cells) die, making immediate medical intervention critical.
A “mini-stroke” – a transient ischemic attack (TIA) – may serve as a life-saving and critical early warning sign of a greater and more devastating stroke to follow.
That’s the word from Dr. Peter M. Rothwell, a professor of clinical neurology at the University of Oxford (England) and senior author of a study in the June 2, 2009 issue of American Academy of Neurology’s journal Neurology.
The study authors note that if you’ve had a TIA you should “seek medical attention immediately, particularly if you have either weakness or speech disturbance that lasts more than ten minutes.
“Don’t wait until the next day – it may be too late.”
A Tia is a momentary blockage of blood flow in an artery of the brain and researchers found that about half of all the recurrent strokes in the seven days after a TIA occur in the first 24 hours – highlighting the need for emergency medical/neurological assessments.
An emergency assessment should include the “ABCD” stroke risk factors:
· A – Age over 60
· B – Blood pressure reading that is high
· C – Clinical symptoms of physical weakness
· D – Duration of the TIA
A stroke is a medical emergency in which every second counts. Among the signs of a stroke are:
· –Sudden numbness or weakness of the face, arm or leg, especially on one side of the body.
· –Sudden confusion, trouble speaking or understanding
· –Sudden trouble seeing in one or both eyes
· –Sudden trouble walking, dizziness, loss of balance or coordination
· –Sudden, severe headache with no known cause

The risk of a major stroke can be reduced by up to 80 percent by initiating standard treatment – aspirin plus or minus clopidogrel [Plavix], statin therapy, blood pressure reduction – immediately after a TIA. Clopidogrel and aspirin are aimed at the clots that cause a stroke by blocking a brain artery. Statins are drugs such as Crestor, Lipitor and Zocor that lower blood cholesterol levels.

According to a new analysis published in the May 28 online issue of Stroke, a potent blood clot-dissolving drug – tissue plasminogen activator (tPA) – can be given up to four-and-a-half hours after the symptoms of a stroke. The study extends by 50 percent the previous 30 hour recommendation.
