A brain attack that resolves on its own within 24 hours. Sometimes called a mini-stroke or TIA, a transient ischemic attack is often an early warning sign of an impending stroke.

A brief attack (from a few minutes to an hour) of cerebral dysfunction of vascular origin, with no persistent neurological deficit.

A transient ischemic attack (TIA) is a stroke that lasts only a few minutes. It happens when the blood supply to part of the brain is briefly blocked. Symptoms of a TIA are like other stroke symptoms, but do not last as long. They happen suddenly, and include Numbness or weakness, especially on one side of the body; Confusion or trouble speaking or understanding speech; Trouble seeing in one or both eyes; Difficulty walking; Dizziness; Loss of balance or coordination. Most symptoms of a TIA disappear within an hour, although they may last for up to 24 hours. Because you cannot tell if these symptoms are from a TIA or a stroke, you should go to the hospital right away. TIAs are often a warning sign for future strokes. Taking medicine, such as blood thinners, may reduce your risk of a stroke. Your doctor might also recommend surgery. You can also help lower your risk by having a healthy lifestyle. This includes not smoking, not drinking too much, eating a healthy diet, and exercising. It is also important to control other health problems, such as high blood pressure and cholesterol.

Recurring, transient episodes of neurologic dysfunction caused by cerebral ischemia; onset is usually sudden, often when the patient is active; the attack may last a few seconds to several hours; neurologic symptoms depend on the artery involved.

A transient episode of cerebral dysfunction of vascular origin with no persistent neurological deficit.

(ischemic attack, transient) Brief reversible episodes of focal, nonconvulsive ischemic dysfunction of the brain having a duration of less than 24 hours, and usually less than one hour, caused by transient thrombotic or embolic blood vessel occlusion or stenosis. Events may be classified by arterial distribution, temporal pattern, or etiology (e.g., embolic vs. thrombotic). (From Adams et al., Principles of Neurology, 6th ed, pp814-6)

A disorder characterized by a brief attack (less than 24 hours) of cerebral dysfunction of vascular origin, with no persistent neurological deficit.

A transient ischemic attack (TIA) is focal brain ischemia that causes sudden, transient neurologic deficits and is not accompanied by permanent brain infarction (eg, negative results on diffusion-weighted MRI). Diagnosis is clinical. Carotid endarterectomy or stenting, antiplatelet drugs, and anticoagulants decrease risk of stroke after...

A transient ischemic attack (TIA) is an acute episode of temporary neurologic dysfunction that results from focal cerebral, spinal cord, or retinal ischemia, and is not associated with acute tissue infarction. The clinical symptoms of TIA typically last less than 1 hour and often last for less than 30 minutes, but prolonged episodes can...

A transient ischemic attack (TIA) is a temporary period of symptoms similar to those of a stroke. A TIA usually lasts only a few minutes and doesn't cause permanent damage.

A transient ischemic attack (TIA) is a transient episode of neurologic dysfunction caused by focal brain, spinal cord, or retinal ischemia, without acute infarction. This replaced the former definition of focal neurologic impairment lasting less than 24 hours. The majority of TIAs resolve within the first hour, and diagnostic imaging...
