Transient Ischemic Attack (TIA)

Transient Ischemic Attack (TIA)

Transient Ischemic Attack (TIA)
A transient ischemic attack (TIA) is also called a mini-stroke or warning stroke. You may have stroke-like symptoms, but they usually go away and cause no permanent damage. If you seek prompt treatment, you may be able to reduce your risk of a permanent stroke later. TIAs happen as a result of a blood clot that clogs an artery in your brain, but unlike a stroke, the symptoms last usually about a minute and then dissipate. It's important to recognize TIA symptoms and seek treatment from your doctor. Sometime called a "pre-stroke," TIAs can occur just days or many months before a stroke. Symptoms include sudden numbness or weakness in the face, arm or leg on one side of your body; sudden confusion; inability to speak or understand someone else; vision problems in one or both eyes; trouble walking, dizziness or a sudden severe headache.

    Having a transient ischemic attack (TIA), also called a mini-stroke or a warning stroke, raises your risk for a full stroke. This is especially true in the first few days after a TIA. If you've had a TIA, your doctor will prescribe treatment and lifestyle changes to prevent a future stroke. After a TIA, see your doctor regularly for follow ups, to be sure your medications and other treatments are working, and to check for any warning signs of a stroke. Get emergency help immediately if you have any of these signs of a stroke:
    • Sudden numbness or muscle weakness, especially on one side of your body
    • Confusion or problems with understanding
    • Trouble speaking or seeing
    • Sudden, severe headache
    • Dizziness or loss of balance

    Dr. Carolyn Brockington - What should people know about a transient ischemic attack (TIA)?
    A transient ischemic attack (TIA), often called a mini-stroke, is an interruption of blood flow to the brain that is not long enough to cause injury. Watch me explain how a TIA can be a key warning sign for a stroke.

    Dr. Carolyn Brockington - Can a transient ischemic attack (TIA) cause brain damage?
    A transient ischemic attack (TIA) doesn't interrupt blood flow long enough to cause injury to the brain, but it's a major warning sign for stroke. Watch me explain the symptoms, and why a TIA should never be ignored.

    As many as 10% to 20% of people who have a transient ischemic attack (TIA), will suffer a full-blown stroke within 90 days, with the greatest risk in the first week. That's why it's so important to seek medical help promptly because the fact that symptoms have disappeared does not mean that the danger is over.

    A study in The Lancet underscored the importance of prompt treatment of TIA. In the study, patients who were promptly diagnosed and began preventive treatments (drugs to prevent clotting and to lower blood pressure and cholesterol) within one day of a TIA were 80% less likely to have a stroke within the next 90 days as patients who did not start preventive treatments until three weeks after a TIA.

    The American Heart Association and American Stroke Association (AHA/ASA) stroke guidelines, which provide direction for physicians throughout the nation, reflect the urgent need to determine the cause of a TIA so that damage can be minimized. The AHA/ASA consensus is that someone with a TIA should be evaluated with MRI within 24 hours and hospitalized if found to be at high risk for an impending stroke.

    A transient ischemic attack (TIA) is a stroke-like attack that lasts for a few minutes to an hour and can involve one or more of these symptoms:
    • Weakness, numbness, or tingling on one side of the body
    • Inability to speak clearly
    • Inability to control the movement of an arm or leg
    • Losing vision in one eye
    Don't ignore these symptoms, even if they go away quickly -- see a doctor. A TIA is a warning sign of carotid artery disease and a possible stroke in the future.

    The symptoms of migraine aura may be visual, sensory or motor and may be mistaken for a TIA, as both can be associated with a headache. Generally speaking TIA symptoms are more abrupt in onset and occur in individuals with more cardiovascular risk factors. TIA symptoms are more likely to consist of a loss of function, such as loss of vision, loss of sensation, limb paralysis, and difficulty speaking or swallowing.

    Migraine aura symptoms are more gradual and consist of positive visual symptoms like bright lights, zigzag patterns, kaleidoscope-like or blurred vision. Tingling and heaviness may occur in the limbs on one side, while a complete paralysis is rare. Speech disturbance is also uncommon.

    TIA vs. Stroke
    A transient ischemic attack (TIA), or mini stroke, differs from a full stroke. In this video, Samuel Rougas, MD, explains the difference and why you should seek help immediately if you believe you or a loved one are showing signs of either condition.

    A mini-stroke, also called a transient ischemic attack (TIA), is a stroke that lasts for a few seconds to a few hours. Stroke symptoms come and then disappear. A mini-stroke can happen when a blood clot temporarily blocks a blood vessel in your brain. Your body may release certain proteins to dissolve the clot. If it is successful, your symptoms may go away.

    A mini-stroke should not be ignored. It can be a warning sign that a larger stroke is going to happen.

    Transient ischemic attacks (TIAs) are often warning signs that a person is at risk for a more serious and debilitating stroke. About one-third of those who have a TIA will have an acute stroke sometime in the future. Many strokes can be prevented by heeding the warning signs of TIAs and treating the underlying risk factors. The most important treatable factors linked to TIAs and strokes are high blood pressure, cigarette smoking, heart disease, carotid artery disease, diabetes, and heavy use of alcohol. Medical help is available to reduce and eliminate these factors. Lifestyle changes, such as eating a balanced diet, maintaining healthy weight, exercising, and enrolling in smoking and alcohol cessation programs can also reduce these factors.

    Since there is no way to differentiate between the symptoms of a transient ischemic attack (TIA) or an acute stroke, patients should assume that all stroke-like symptoms signal an emergency and should not wait to see if they go away. A prompt evaluation (within 60 minutes) is necessary to identify the cause of the TIA and determine appropriate therapy. Depending on a patient's medical history and the results of a medical examination, the doctor may recommend drug therapy or surgery to reduce the risk of stroke in people who have had a TIA. The use of antiplatelet agents, particularly aspirin, is a standard treatment for patients at risk for stroke. People with atrial fibrillation (irregular beating of the heart) may be prescribed anticoagulants.
