While a transient ischemic attack (TIA) may increase your risk of stroke in the future, prompt medical treatment may minimize this risk and increase the likelihood of a long, full life.
A transient ischemic attack (TIA), also called a “ministroke,” is caused by a temporary blockage of a blood vessel in or around the brain. A TIA can cause stroke-like symptoms that usually resolve within
Although a TIA typically doesn’t cause lasting symptoms, it may put you at an
Read on to learn more about how having a TIA affects your life expectancy.
The symptoms of a transient ischemic attack (TIA) usually resolve in less than an hour, though, in some situations, the symptoms may persist for up to 24 hours. Because it’s not possible to tell the difference between a TIA and stroke symptoms, it’s vitally important to get prompt medical attention.
Even though TIA symptoms usually don’t cause long lasting complications, getting evaluated soon after your symptoms begin may help a medical team find the underlying cause of your TIA. Accurate diagnosis of your condition and treatment can go a long way toward reducing your risk of a sudden, possibly life threatening, stroke in the future.
The risk of a stroke after a TIA seems to be particularly high within the first
TIA and long-term stroke risk
In a large
Out of this large group of people, 435 experienced a TIA. The researchers matched these people with a control group of 2,175 people who didn’t develop a TIA.
The authors found that 130 people (29.5%) who had a TIA went on to have a stroke. The time period between a TIA and stroke among this group was as follows:
- 28 strokes (21.5%) occurred within 7 days
- 40 strokes (30.8%) occurred within 30 days
- 51 strokes (39.2%) occurred within 90 days
- 63 strokes (48.5%) occurred after more than 1 year
The researchers found that the risk of having a stroke was 4.37 times greater (95% confidence intervals of 3.30–5.71) in people who had a TIA than in people who didn’t.
TIA and risk of stroke death
In a 2022 study, researchers examined the outlook of 20,633 people who experienced a TIA between 1986 and 2017.
The researchers found that the risk of death was higher in all age groups among people who experienced a TIA compared with people in the same age range who didn’t have a TIA:

A variety of factors may influence your life expectancy after you have a TIA. Let’s look at these factors more closely.
Urgent assessment and treatment
Receiving a prompt medical evaluation and treatment after a TIA may significantly decrease your risk of having a future stroke.
In the follow-up study, researchers found that stroke risk continued to be reduced even after 10 years.
Younger age of first TIA
In a 2022 study, researchers found that people who had their first TIA between the ages of 39 and 60 were at the highest risk of dying during a follow-up period of up to 30 years compared with people who had their first TIA when they were older.
Aspirin, antiplatelet, or anticoagulation medication
In the same 2022 study as above, the researchers found that people between the ages of 39 and 60 who were prescribed aspirin after a TIA had a reduced risk of stroke compared with people who weren’t prescribed any antiplatelet therapy.
For people whose TIA may have been caused by atrial fibrillation, anticoagulation medication (blood thinner), such as Eliquis or Xarelto, is often prescribed. Blood thinners can lower the risk of a blood clot forming if the heart starts beating in an irregular rhythm in the future.
People with overweight or obesity are at an increased risk of having a stroke, but there’s

“Revascularization” refers to a group of procedures that can restore proper blood flow to blocked arteries.
If a TIA is caused by a buildup of plaque in the carotid artery, known as “carotid artery stenosis,” blood flow to the brain can be restored with procedures such as carotid endarterectomy or carotid stenting.
Many people who experience a TIA go on to live a long life and never experience a stroke. Getting prompt medical attention and treatment can help minimize your risk of developing a future stroke.
Taking steps to reduce your risk of a stroke can also help minimize your risk of premature death.

It’s possible to have multiple TIAs. TIAs can occur many years apart or within hours to days.
TIAs are called “dual TIAs” when they occur twice. TIAs are known as “crescendo TIAs” when they occur multiple times in succession.
Crescendo TIAs are reported in less than 5% of people who have TIAs, but they have a high risk of developing into a stroke.
Having a TIA puts you at an elevated risk of having a more severe stroke in the future, especially in the 3 months after a TIA. Getting immediate medical attention and receiving a timely diagnosis and treatment are important steps in helping to reduce your risk of a future stroke.
Many people who have a TIA go on to live a long, full life. Following a doctor’s advice, making specific lifestyle changes, and managing other health conditions such as diabetes, hypertension, or heart disease, are key steps in reducing your stroke risk and prolonging your life.
