You may have more than one TIA , and the recurrent signs and symptoms may be similar or different depending on which area of the brain is involved.
The length of TIAs differs for individuals but symptoms do not last more than 24 hours. 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).
Approximately one in three American adults has experienced a symptom consistent with a “mini-stroke,” sometimes called a transient ischemic attack (TIA).
The disruption in blood supply results in a lack of oxygen to the brain. This can cause sudden symptoms like those of a stroke. However, a TIA does not last as long as a stroke. The effects only last for a few minutes or hours and fully resolve within 24 hours.
If the person researches what causes mini-strokes, they will discover that 90 percent are caused by plaque-filled blood vessels blocking the blood flow to the brain or by a blood clot that travels from other parts of your body — like the heart — to the brain. The above mentioned can be caused by: Smoking.
TIAs look like strokes in terms of signs and symptoms, but they are temporary. In other words, they leave no lasting brain damage or residual symptoms. However, they serve as a warning sign that a person is at higher risk of a major stroke and should seek immediate medical attention.
Key points. 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.
Most people who have a mini-stroke feel fine after the event. In fact, many people don't even realize they've had one! Symptoms might include weakness, numbness, tingling, vision changes or difficulty speaking. Most symptoms are temporary and dissipate within minutes but sometimes can last up to 24 hours.
Some people have strokes without realizing it. They're called silent strokes, and they either have no easy-to-recognize symptoms, or you don't remember them. But they do cause permanent damage in your brain. If you've had more than one silent stroke, you may have thinking and memory problems.
Mini strokes can occur before larger ones as a warning. Both have the same risk factors, including high blood pressure, high cholesterol, diabetes, smoking, and obesity – all of which can cause plaque buildup in the arteries that can lead to blood clots.
“Ignoring any stroke sign could be a deadly mistake,” says Mitch Elkind, M.D., chair of the American Stroke Association. The Association recommends calling for emergency help immediately, even if the symptoms go away. Acting fast can improve your chances of accurate diagnosis, treatment and recovery.
You will likely have a head CT scan or brain MRI. A stroke may show changes on these tests, but TIAs will not.
Chronic stress can indirectly cause a stroke or TIA (transient ischemic attack or mini stroke). For instance, chronic stress can lead to high blood pressure, which is a known risk factor for stroke and heart disease. Stress can also cause inflammation in the arteries all over the body.
Here's something you probably won't hear in the emergency room: A transient ischemic attack (TIA, or mini-stroke) can have symptoms that last for months or years afterward. Many healthcare providers think these symptoms are rare or at least short term, but a 2013 survey from the UK Stroke Association showed otherwise.

Benefits and risks of blood-thinning medication
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.
age – although TIAs can happen at any age (including in children and young adults), they're most common in people over 55.
One of the most common stroke mimics is a seizure, which researchers believe account for as many as 20% of all stroke mimics. Other common stroke mimics include migraines, syncope, sepsis, brain tumor and metabolic derangement (low sodium or low blood sugar).
Once your provider has determined the cause of the TIA , the goal of treatment is to correct the issue and prevent a stroke. Depending on the cause of the TIA , your provider may prescribe medication to reduce the tendency for blood to clot or may recommend surgery or a balloon procedure (angioplasty).
A TIA is a temporary clot in your brain, so it doesn't always cause damage that would show up on a scan. If doctors are not sure what caused your symptoms, you may have a magnetic resonance imaging scan (MRI). This can rule out other causes of the symptoms, such as bleeds or abnormalities in the brain.
TIAs are sometimes called “warning strokes” and tend to happen multiple times. In many cases, TIAs are followed by strokes, usually within a year of the first attack. TIAs may be caused by a variety of factors, including: Narrowing of the arteries, usually caused by atherosclerosis.
If a person has several smaller strokes over time, multiple infarcts will build up in their brain. They may eventually develop dementia if the combined damage of all these infarcts is enough to cause problems with memory, thinking or reasoning.
Although a TIA should not have a long-term impact on your daily activities, you must stop driving immediately. If your doctor is happy that you have made a good recovery and there are no lasting effects after 1 month, you can start driving again.
