Transient ischemic attacks (TIAs) have been shown to be a strong predictor of subsequent stroke and death. Transient ischemic attacks usually last a few minutes. Most signs and symptoms disappear within an hour. The signs and symptoms of TIA resemble those found early in a stroke and may include sudden onset of: • Weakness, numbness or paralysis in your face, arm or leg, typically on one side of your body • Slurred or garbled speech or difficulty understanding others • Blindness in one or both eyes or double vision • Dizzinessor loss of balance or coordination Hill et al found that the risk of stroke after TIA in Canada was 9.5% at 90 days, and 14.5% at 1 year. A transient ischemic attack has the same origins as that of an ischemic stroke, the most common type of stroke. In an ischemic stroke, a clot blocks the blood supply to part of your brain. In a transien Anti-platelet drugs. These medications make your platelets, one of the circulating blood cell types, less likely to stick together.
When blood vessels are injured, sticky platelets begin to form clots, a process completed by clotting proteins in blood plasma. The most frequently used anti-platelet medication is aspirin. Aspirin is also the least expensive treatment with the fewest potential side effects. An alternative to aspirin is the anti-platelet drug clopidogrel (Plavix). Your doctor may consider prescribing Aggrenox, a combination of low-dose aspirin and the anti-platelet drug dipyridamole, to reduce blood clotting. The way dipyridamole works is slightly different from aspirin. t ischemic attack, unlike a stroke, the blockage is brief, and there is no permanent damage.
