TIA

Transient Ischemic Attack (TIA)

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.

Often called a ministroke, a TIA may be a warning. About 1 in 3 people who has a TIA will eventually have a stroke, with about half occurring within a year after the TIA.

A TIA can serve as both a warning of a future stroke and an opportunity to prevent it.

Transient ischemic attacks usually last a few minutes. Most signs and symptoms disappear within an hour, though rarely symptoms may last up to 24 hours. The signs and symptoms of a TIA resemble those found early in a stroke and may include sudden onset of:

Weakness, numbness or paralysis in the face, arm or leg, typically on one side of the body
Slurred or garbled speech or difficulty understanding others
Blindness in one or both eyes or double vision
Vertigo or loss of balance or coordination

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 TIA. Prompt evaluation and identification of potentially treatable conditions may help you prevent a stroke.

If you or someone you know is experiencing symptoms of TIA, please take it seriously and seek immediaate medical attention as soon as possible. Prompt evaluation and identification of potentially treatable conditions may help you prevent a stroke.
