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.
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.
Most TIAs result from narrowing of the major arteries to the brain, such as the carotid arteries. These blood vessels provide oxygenated blood to brain cells. These arteries can become clogged with fatty deposits, called plaques. Plaques partially block the artery, and can lead to the formation of a blood 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).
Although the symptoms of a transient ischaemic attack (TIA) resolve in a few minutes or hours without any specific treatment, you'll need treatment to help prevent another TIA or a full stroke from happening in the future. A TIA is a warning sign that you're at increased risk of having a full stroke in the near future.
Streib recommends that all patients visit an emergency room during or immediately after a TIA to receive imaging of their brain and blood vessels. These scans can inform patients and providers of the cause of their TIA and their immediate stroke risk. Scans also help them decide upon a treatment plan.
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.
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.
The signs of a stroke often appear suddenly, but that doesn't mean that you won't have time to act. Some people will experience symptoms such as headache, numbness or tingling several days before they have a serious stroke.
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.
TIAs are often an early warning sign that a person is at risk of stroke. 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 .
A transient ischemic attack (TIA) is a stroke that usually lasts under five minutes, and symptoms and the cause (blood clot) resolve on their own. But just because the symptoms disappear, does not mean a TIA should be ignored.
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.
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.
Always treat a TIA as seriously as you would a stroke. "Even though the symptoms resolve, there might be damage to the brain, so you need to see a neurologist," Dr. Rost advises.
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.
Taking blood-thinning medication is often one of the main ways you can reduce your risk of a stroke if you have had a stroke or TIA, or have a heart condition. By reducing the risk of clots forming, they give you a much greater chance of recovering and staying healthy after a stroke.
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).
The short answer is “no.”
TIA is a temporary blockage of blood flow to the brain. It causes brief stroke-like symptoms, such as weakness or facial drooping that go away, and the brain starts working normally again. It doesn't cause permanent damage, so patients often ignore it.
A transient ischaemic attack (TIA or mini-stroke) is the same as a stroke, but the symptoms last a short time. You get stroke symptoms because a clot is blocking the blood supply in your brain. When the clot moves away, the stroke symptoms stop.
Sometimes a TIA is caused by a sharp drop in blood pressure that reduces blood flow to the brain. This is called a "low-flow" TIA. It is not as common as other types.
