Transient Ischemic Attack (TIA)
|
| Definition |
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.
|
| Causes |
Transient ischemic attacks occur
when blood flow to certain areas of the brain is slowed.
|
| Treatment |
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.
|
| Comments |
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.
