Transient Ischemic Attack (TIA)


Transient ischemic attacks are episodes of temporary loss of certain parts of brain function. They are followed by rapid and complete return to normal brain functioning. Death of brain tissue does not occur. Symptoms are gone within 30 minutes to 24 hours.


Transient ischemic attacks occur when blood flow to certain areas of the brain is slowed.


Testing is often performed to determine the cause of the TIA. Treatment is aimed at the cause and often involves use of a type of blood thinner.


Transient ischemic attacks are important because they may be an early warning sign that a stroke may occur. A full evaluation is warranted. Many people die from strokes each year. Brain cell death does not occur with TIA, whereas brain cell death does occur with stroke.
