A transient ischemic attack (TIA) is like a stroke, producing similar symptoms, but usually lasting only a few minutes and causing no permanent damage.
Often called a ministroke, a transient ischemic attack may be a warning. About 1 in 3 people who have a transient ischemic attack will eventually have a stroke, with about half occurring within a year after the transient ischemic attack.
A transient ischemic attack can serve as both a warning and an opportunity — a warning of an impending stroke and an opportunity to take steps to prevent it.

Transient ischemic attacks usually last a few minutes. Most signs and symptoms disappear within an hour. The signs and symptoms of a TIA resemble those found early in a stroke and may include sudden onset of:
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.
Since TIAs most often occur hours or days before a stroke, seeking medical attention immediately following a possible TIA is essential. Seek immediate medical attention if you suspect you’ve had a transient ischemic attack. Prompt evaluation and identification of potentially treatable conditions may help you prevent a stroke.
A transient ischemic attack has the same origins as that of an ischemic stroke, the most common type of stroke. In an ischemic stroke, a clot blocks the blood supply to part of your brain. In a transient ischemic attack, unlike a stroke, the blockage is brief, and there is usually no permanent damage.
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 your brain.
Plaques can decrease the blood flow through an artery or lead to the development of a clot. A blood clot moving to an artery that supplies your brain from another part of your body, most commonly from your heart, also may cause a TIA.
Some risk factors for a transient ischemic attack and stroke can’t be changed. Others you can control.
You can’t change the following risk factors for a transient ischemic attack and stroke. But knowing you’re at risk can motivate you to change your lifestyle to reduce other risks.
You can control or treat a number of factors — including certain health conditions and lifestyle choices — that increase your risk of a stroke. Having one or more of these risk factors doesn’t mean you’ll have a stroke, but your risk particularly increases if you have two or more of them.
Knowing your risk factors and living healthfully are the best things you can do to prevent a TIA. Included in a healthy lifestyle are regular medical checkups. Also:
