What You Should Know About Transient Ischemic Attacks - Oren Zarif - Transient Ischemic Attack

If you've experienced a TIA, you should seek medical attention immediately. Though the symptoms usually subside after an hour or two, some may persist up to 24 hours. Depending on the circumstances, your doctor may prescribe a blood-thinner or recommend surgery to reduce the risk of further complications. You should also live a healthy lifestyle, including eating a nutritious diet and exercising regularly. A good TIA prevention strategy involves controlling high blood pressure, quitting smoking, and following a healthy diet.

Although transient ischemic attacks usually do not cause permanent damage, they can serve as warning signs for future strokes or other conditions. A transient ischemic attack, in fact, can be a precursor to an underlying heart problem. In the latter case, a heart problem may be the culprit. It's vital to get immediate medical help, and follow up with regular checkups to make sure you don't develop another TIA.

While a transient ischemic attack does not usually result in permanent brain damage, it is an important warning sign of a more severe stroke. A TIA is characterized by an episode of sudden neurologic deficits in a specific arterial territory. In general, a TIA resolves within one hour. You should seek medical attention immediately if you suspect you may have had a transient ischemic attack.

A TIA usually occurs because a large artery, called the carotid artery, has narrowed. Over time, plaque forms and partially blocks these arteries. Blood clots then form, causing the artery to become completely blocked. The clot travels through the bloodstream to other smaller branches of the artery and ultimately blocks blood flow to the area of the brain that the artery supplies.

Despite its short duration, a TIA is an important warning sign that you may be at risk for a stroke. It can reduce your chances of a stroke by identifying the symptoms early and seeking medical attention. A TIA may be a precursor to a major stroke and, thus, should be treated immediately. The symptoms of a transient ischemic attack are similar to those of a stroke, so you should seek medical attention right away.

Diagnosis is important for people suffering from TIA, so a physician will perform an examination and diagnostic tests. The doctor will test your vision, muscle strength, and ability to think and speak. A scan of the brain is also helpful. A carotid endarterectomy may be necessary if the blockage is severe. Other tests may include a heart ultrasound. An ultrasound scan can also reveal blocked blood vessels in the neck.

While TIAs are self-resolving and temporary, they are associated with increased risks of subsequent ischemic strokes. As a result, treatment for TIAs is focused on preventing a recurrence of stroke. Optimal management depends on the underlying cause of the transient ischemic attack. When a TIA occurs in a person, it is important to identify the cause and correct it as soon as possible.

Symptoms of TIA can be similar to those of a stroke, but with a different diagnosis. A temporary clot lodged in an artery carrying oxygenated blood to the brain causes a decrease in brain function. The clot, however, usually breaks up within a few minutes, so the affected part of the brain only suffers a brief period of lack of oxygen. This is very different from a stroke, in which brain tissue dies.

If you are concerned about your TIA symptoms, it is important to seek medical attention immediately. This is vital because if the symptoms persist for more than a few days, a stroke could occur. A medical professional can investigate the cause of your symptoms and offer treatment and reassurance. They will also give you long-term medication. You should take these medications if they are prescribed by your doctor. You may also be given a temporary medication to prevent further symptoms.

A TIA diagnosis should be made by a physician with experience in treating these cases. The symptoms of transient ischemic attack (TIA) are often similar to those of a stroke. Diagnostic tests should include carotid stenosis and cardiac sources of emboli. The patient should also be tested for hematologic abnormalities and screening for stroke risk factors. The evaluation process for TIA is rapid, and the risk of a stroke is highest in the first 24 to 48 hours following the onset of symptoms.

Treatment of TIA depends on the cause and severity of the underlying disease. Ultrasound testing is the safest, quickest, and least expensive means of evaluating extracranial cerebrovascular disease. It has been recommended as the initial test for identifying significant carotid stenosis. Duplex ultrasonography (DUS) and Doppler flow-velocity measurements are helpful tools during carotid territory ultrasounds.
