Learn About Transient Ischemic Attack (TIA)
A transient ischemic attack (TIA) occurs when blood flow to a part of the brain stops for a brief time. A person will have stroke-like symptoms for up to 24 hours. In most cases, the symptoms last for 1 to 2 hours.
A transient ischemic attack is a warning sign that a true stroke may happen in the future (often near future) if something is not done to prevent it.

A TIA is different than a stroke. After a TIA, the blockage breaks up quickly and dissolves on its own. A TIA does not cause brain tissue to die.
The loss of blood flow to an area of the brain can be caused by:
- A blood clot in an artery of the brain
- A blood clot that travels to the brain from somewhere else in the body (for example, from the heart)
- An injury to blood vessels
- Narrowing of a blood vessel in the brain or leading to the brain
High blood pressure is the main risk factor for TIAs and stroke. Other major risk factors are:
- Irregular heartbeat called atrial fibrillation
- Diabetes
- Family history of stroke
- Being male
- High cholesterol
- Tendency to have abnormal blood clotting
- Increasing age, especially after age 55
- Ethnicity (African Americans are more likely to die of stroke)
- Smoking
- Alcohol use
- Recreational drug use
- History of prior TIA or stroke
People who have heart disease or poor blood flow in their legs caused by narrowed arteries are also more likely to have a TIA or stroke.
Symptoms begin suddenly, last a short time (from a few minutes to 1 to 2 hours), and go away. They may occur again at a later time.
The symptoms of a TIA are the same as the symptoms of a stroke, and include:
- Change in alertness (including sleepiness or unconsciousness)
- Changes in the senses (such as hearing, vision, taste, and touch)
- Mental changes (such as confusion, memory loss, difficulty writing or reading, trouble speaking or understanding others)
- Muscle problems (such as weakness, trouble swallowing, trouble walking)
- Dizziness or loss of balance and coordination
- Lack of control over the bladder or bowels
- Sensation problems (such as numbness or tingling on one side of the body)
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. You will be encouraged to make lifestyle changes to reduce your risk of further symptoms. Changes include quitting smoking, exercising more, and eating healthier foods.
You may receive blood thinners, such as aspirin, heparin, warfarin (Coumadin), or direct acting oral anticoagulants (DOACs) to reduce blood clotting. Some people who have blocked neck arteries may need surgery (carotid endarterectomy). If you have an irregular heartbeat (atrial fibrillation) or other heart problems, you will be treated to avoid future complications.

TIAs do not cause lasting damage to the brain.
But, TIAs are a warning sign that you may have a true stroke in the coming days or months. Some people who have a TIA will have a stroke within 3 months. Half of these strokes happen during the 48 hours after a TIA. The stroke may occur that same day or at a later time. Some people have only a single TIA, and others have more than one TIA.
You can reduce your chances of a future stroke by following up with your provider to manage your risk factors.
A TIA is a medical emergency. Call 911 or the local emergency number right away. Do not ignore symptoms just because they go away. They may be a warning of a future stroke.
Follow your provider's instructions on how to prevent TIAs and strokes. You will likely be told to make lifestyle changes and take medicines to treat high blood pressure or high cholesterol.
Summary: The purpose of this study is to learn more about stroke and obtain information that may serve as the basis for future investigations. It will 1) establish a registry of patients with cerebrovascular disease (stroke); 2) characterize the natural history of acute stroke and transient ischemic attacks (TIA)-an interruption of blood flow to the brain that causes stroke symptoms for a short period of t...
Summary: The primary objective is to describe in the real-world setting patient characteristics and outcomes of patients with primary hypercholesterolaemia (heterozygous familial and non-familial) or mixed dyslipidaemia using bempedoic acid and/or its fixed-dose combination with ezetimibe in managing plasma levels of low-density lipoprotein cholesterol (LDL-C). Secondary objectives are to document and eval...
