Dipyridamole and aspirin — Dipyridamole is a medication that may be given after a TIA to reduce the risk of stroke. It is often given as an extended-release form, combined with aspirin (aspirin-extended-release dipyridamole, brand name: Aggrenox). It is taken two times per day.
Aspirin and other antiplatelet medicines
You'll probably be given low-dose aspirin straight after a suspected TIA. Aspirin works as an antiplatelet medicine. Platelets are blood cells that help blood to clot. Antiplatelet medicines work by reducing the ability of platelets to stick together and form blood clots.
If you have had a TIA or an ischaemic stroke you will almost always need to take blood-thinners. There are two types of blood thinners: Antiplatelet medication. Antiplatelet medicines stop tiny blood cells called platelets from sticking together and forming a blood clot.
The difference is TIA symptoms resolve within minutes, although they can last as long as 24 hours. Doctors call TIAs mini-strokes or warning strokes, because if you have a TIA, you are at higher risk for stroke later. TIA recovery is quick—as soon as symptoms stop.
The underlying cause of a TIA often is a buildup of cholesterol-containing fatty deposits called plaques (atherosclerosis) in an artery or one of its branches that supplies oxygen and nutrients to the brain. Plaques can decrease the blood flow through an artery or lead to the development of a clot.
Some people might have more than one TIA and it is possible to have several TIAs in a short space of time (for example, several TIAs within a day).
If you have had a TIA within the last 48 hours, you will likely be admitted to the hospital so that doctors can search for the cause and monitor you. High blood pressure, heart disease, diabetes, high cholesterol, and blood disorders will be treated as needed.
How long you stay in the hospital depends on your symptoms and the treatment received. The average amount of time to stay in the hospital after a TIA is 2 to 3 days.
The clot dissolves on its own and all symptoms resolve within 24 hours. Although TIA isn't a stroke, the condition should be treated just as seriously. Experiencing TIA is a warning that you may be at high risk for a stroke. To address this risk, it should be treated immediately.
Higher levels of stress, hostility and depressive symptoms are associated with significantly increased risk of incident stroke or TIA in middle-aged and older adults.
A type of irregular heartbeat called atrial fibrillation can also cause a TIA. It can lead to the formation of blood clots that escape from the heart and become lodged in the blood vessels supplying the brain.
In a previously reported study, 31% of TIA patients showed an acute infarction visualized by MRI including DWI. A strong association was found between neurological symptoms, speech dysfunction and weakness and an evidence of acute infarction by MRI including DWI (Al-Khaled and Eggers, 2013).
However, mounting evidence suggests that an MRI within 1 to 2 days of a TIA could spot evidence of a stroke that may disappear in time. MRIs can detect tissue damage even when symptoms are temporary. The sophisticated imaging technique can detect stroke lesions that may become less apparent quickly.
You will likely have a head CT scan or brain MRI. A stroke may show changes on these tests, but TIAs will not.
Unlike a stroke, TIA symptoms do not persist and resolve within 24 hours – and often much faster. A TIA doesn't leave any permanent brain damage or cause lasting neurologic problems.
About 1 in 3 people who has a TIA goes on to experience a subsequent stroke. The risk of stroke is especially high within 48 hours after a TIA . The symptoms of a TIA are similar to those of a stroke and include: Numbness or muscle weakness, usually on one side of the body.
TIA reduces survival by 4% in the first year and by 20% within 9 years. TIA has a minimal effect on mortality in patients <50 years but heralds significant reduction in life expectancy in those >65 years.
A TIA is a warning that you're at risk of having a full stroke in the near future. An assessment can help doctors determine the best way to reduce the chances of this happening.
Call 9-1-1 immediately if any of these signs of stroke appear: Numbness or weakness in the face, arm, or leg; Confusion or trouble speaking or understanding speech; Trouble seeing in one or both eyes; Trouble walking, dizziness, or problems with balance; severe headache with no known cause.
A TIA has the same symptoms as a stroke, but they are temporary as the clot naturally dissolves or is dislodged from the blockage. While it is sometimes called a mini stroke, a TIA does not usually cause long-term brain damage. A person who has had a TIA is at greater risk of having a stroke or heart attack.
You must stop driving for at least 1 month after a transient ischaemic attack ( TIA ) or mini-stroke. This includes amaurosis fugax or retinal artery fugax. You can restart only when your doctor tells you it is safe.
Transient ischemic attack and minor stroke are highly predictive of a subsequent disabling stroke within hours or days of the first event. The risk of subsequent stroke after a transient ischemic attack is between 2% and 17% within the first 90 days after the initial event.
