- TIAs are often indicative of underlying health problems that can cause real strokes in the future. More than 10 percent of TIA patients have a stroke within three months. It is important to take mini strokes seriously to prevent a possible life-threatening event.

What is a transient ischemic attack (TIA)? When the doctor has identified what caused the TIA his/her aim is to treat it, thus minimizing the risk of a subsequent stroke. The doctor may prescribe medication which lowers the risk of a blood clot, or recommend surgery or an angioplasty; this will depend on the cause of the TIA.

- A transient ischemic attack (TIA) results from a sudden, temporary lack of blood flow to your brain. This can cause symptoms similar to a stroke, such as weakness, difficulty speaking, and numbness. The main difference between a TIA and a stroke is that the symptoms of a TIA occur quickly and last for a short amount of time.

Transient ischaemic attack (TIA) A transient ischaemic attack (TIA) is caused by a temporary cut in blood supply to the brain, due to the partial blockage of an artery by a blood clot or debris. 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.

- This stops blood flow through the artery and damages brain cells. Heart conditions and blood disorders also can cause blood clots that can lead to a stroke or TIA. For example, atrial fibrillation (A-tre-al fi-bri-LA-shun), or AF, is a common cause of embolic stroke. In AF, the upper chambers of the heart contract in a very fast and irregular way.

Causes Transient ischaemic attacks (TIAs) occur when one of the blood vessels that supply your brain with oxygen-rich blood becomes blocked. This interruption in the flow of blood to the brain means that the brain cannot carry out some of its normal functions properly, leading to symptoms such as slurred speech and weakness.

- Symptoms of a TIA are the same as symptoms of a stroke. But symptoms of a TIA don't last very long. Most of the time, they go away in 10 to 20 minutes.

Stroke and Traumatic Brain Injury TIAs are “mini strokes” that produce fleeting, stroke like symptoms, but no lasting damage. People who experience TIAs are 10 times more likely to have a stroke. Stroke is the third leading cause of death in the United States-someone has a stroke every 53 seconds. It is a leading cause of disability.

Slideshow: A Visual Guide to Understanding Stroke 'Mini-Stroke' (TIA). A transient ischemic attack, often called a mini-stroke, is more like a close call. Blood flow is temporarily impaired to part of the brain, causing symptoms similar to an actual stroke. When the blood flows again, the symptoms disappear. A TIA is a warning sign that a stroke may happen soon. It's critical to seek emergency medical help if you think you've had a TIA.

WARNING SIGNS OF HEART ATTACK, STROKE & CARDIAC ARREST A TIA or transient ischemic attack is a warning stroke or mini-stroke that produces stroke-like symptoms. TIA symptoms usually only last a few minutes but, if left untreated, people who have TIAs have a high risk of stroke. Recognizing and treating TIAs can reduce the risk of a major stroke.

Transient Ischemic Attack (TIA) - Topic Overview A transient ischemic attack (TIA) happens when blood flow to part of the brain is blocked or reduced, often by a blood clot. After a short time, blood flows again and the symptoms go away.With a stroke, the blood flow stays blocked, and the brain has permanent damage.fter the clot dissolves, blood flow returns, and the symptoms go away. 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.

Transient Ischemic Attack (TIA) - Topic Overview A blood clot is the most common cause of a TIA. Blood clots can be the result of hardening of the arteries (atherosclerosis), heart attack, or abnormal heart rhythms. The clot can block blood flow to part of the brain. Brain cells are affected within seconds of the blockage. That causes symptoms in the parts of the body controlled by those cells.

- TIAs are usually caused by a clot that blocks blood flow. Plaque, often called atherosclerosis, can build up in your arteries, narrowing the space blood flows through or causing a clot to develop. Some other conditions that can cause TIAs include: 1  A weakened, bulging heart wall (ventricular aneurysm). 2  A rapid, irregular heartbeat (atrial fibrillation). 3  Narrowing of the main artery in your neck, the carotid artery. 4  Blood clotting problems.

Overview You may have experienced TIA, an important sign that you're at risk of a full-blown stroke. Talk to your doctor if you have risk factors for carotid artery disease.

Stroke TIAs have the same symptoms as a stroke, but they are temporary and do not usually cause long-term brain damage. A TIA, or mini-stroke, is a warning of an impending stroke. It may appear hours, days, weeks or months before a full stroke, but is more common within days or a few weeks. Just like full strokes, TIAs need emergency treatment and should not be ignored.
