Transient Ischemic Attack (TIA)
1 AnswerRealAge answeredHaving 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:
3 AnswersA transient ischemic attack (TIA), also called a mini-stroke, can be a warning sign for future strokes. If you have a TIA, your risk of having a full-blown stroke is 10 times greater. The risk is highest in the first 48 hours, then remains high over the next three months. There is still a higher risk of stroke three to five years after a mini-stroke.
So if you have had a TIA, it’s very important to see a doctor to find out why it happened and have the problem treated.
1 AnswerDr. Natalia S. Rost, MD , Neurology, answeredAs 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.
2 AnswersIntermountain Healthcare answeredA 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
5 AnswersThe 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.

5 AnswersA 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.
2 AnswersThe 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.
1 AnswerPiedmont Heart Institute answered
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.
