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

    A transient ischemic attack (TIA) is like a “near miss.” Strokes are caused by loss of blood flow to the brain from plaque build-up in brain arteries, or a blood clot formed elsewhere that lodges in the artery flowing into the head. Lost blood flow causes stroke symptoms with permanent damage if the artery remains blocked. If blood flow returns quickly symptoms dissipate. When the body restores blood flow without brain damage this is a transient ischemic attack, or TIA. It increases the risk of having a future stroke.

    A transient ischemic attack (TIA) usually last several minutes to hours and is caused by partial or temporary obstruction of an artery by the same process that causes an ischemic stroke.

    Sometimes a TIA lasts longer, and in such cases there is more significant potential for brain damage even if the TIA never progresses to a full-blown stroke with persistent symptoms. If the TIA's symptoms last as long as 24 hours, it technically becomes a full-blown stroke, and it most likely has caused some type of brain infarction, or tissue death. However, advances in brain imaging have revealed that brain infarction may occur even in TIAs that end much earlier -- and even if symptoms have abated. In these cases, the infarcted tissue is in a "silent" area of the brain, so that damage there produces no symptoms. Or the damaged area may be adjacent to a part of the brain that produced symptoms following the initial injury, but then recovered, so that the symptoms disappeared.

    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.

    A mini stroke, or transient ischemic attack (TIA), is different from a migraine headache. A TIA usually manifests with a sudden onset of loss of function that is transient. Headaches are usually not associated with mini strokes.

    A transient ischemic attack (TIA) occurs when there is a temporary loss of blood flow to a brain region, usually lasting under one hour, causing temporary loss of function but not permanent damage. In a TIA, the patient was lucky – blood flow was spontaneously restored before lasting injury occurred. It is important for patients who have had TIAs to have medical evaluation to find and treat the underlying causes before a permanent stroke occurs.

    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.

    The signs and symptoms of a transient ischemic attack (TIA) go away within 24 hours and there are no remaining deficits or impairments in mental or physical functioning. However, a TIA should be an alarm to start treatment to prevent a stroke, which can lead to long-term deficits or death. The risk of having a stroke within 48 hours after a TIA is 4% to 10%. The risk of having a stroke 6 months after a TIA is approximately 13%. Therefore, a TIA should not be taken lightly. It is important to start medical management to help reduce your chance of stroke. Tests should be done to determine if something led to the TIA that can later lead to a stroke.

    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.
